For Shūichi, this was just a minor accomplishment, hardly worth dwelling on.
With a few strokes of his pen, he recorded the formula for his new Fire Nether Chains and then stored it away. This would be a valuable asset for the the future.
Afterward, his attention turned to the Tag Tree.
The new Fire Nether Chains had been recognized by the Tag Tree as an S-rank sealing technique, which meant he could now activate the Sealing Master tag.
As the tag leaf was filled with a red glow, its effects came into play: sealing and curse mark talent increased by 100%, thought processing speed increased by 100%, and the ability to crystallize a sealing technique into a kekkei genkai with no barriers to learning any non-bloodline-based sealing or curse marks.
"A red tag… So, even Master-level tags can have different ranks!"
Shūichi was overjoyed.
Currently, the strongest tag on his Tag Tree was Prodigy, his only golden tag so far.
But solidifying a sealing technique as a kekkei genkai was astonishing in itself.
Without hesitation, Shūichi chose the Fire Nether Chains, his own S-rank sealing technique.
Immediately, intense pain seared through his body.
It felt like every cell was being branded by fire.
And he could feel his chakra transforming into symbols, forming the Fire Nether Chains formula, compacted a thousand times over and forced directly into his genes.
"So intense…"
Shūichi couldn't help but suck in a cold breath.
This was nothing like his previous experience of learning Lava Release, where the power permeated gradually, quietly making itself known.
But once the pain faded, Shūichi realized a benefit.
By crystallizing the Fire Nether Chains as a kekkei genkai, the Tag Tree had perfected the information, something he couldn't achieve on his own.
This meant that his descendants would inherit the Fire Nether Chains as close to his own level as possible.
And future generations would also have a higher chance of awakening it.
After all, genetic information can lose its integrity through generations.
Of course, for Shūichi himself, having the Fire Nether Chains as a bloodline limit wouldn't enhance his strength directly.
"Even so, the Fire Nether Chains have not yet reached their full potential. There's still room for growth."
Shūichi had high hopes for this sealing technique.
Currently, the Fire Nether Chains were based on Fire Release and Yin Release.
He had considered integrating Yang Release to further enhance its sealing power, aiming to make it Yin-Yang Release.
One day, it might even rival the Six Paths Chibaku Tensei.
Of course, that goal was still a ways off.
Putting that thought aside, Shūichi continued sorting through his latest achievements.
Second goal: Yang Release.
With a clap of his hands, Shūichi was suddenly surrounded by a brilliant green chakra glow.
Instantly, the vitality in each of his cells surged, and his life force skyrocketed.
One times... two times... three times!
At three times the normal level, he reached his limit. He then released his hands, pulled out a kunai, and sliced his arm. The wound opened immediately.
But before any blood could flow, it healed in an instant.
"Not bad—it's not as good as the First Hokage, but it's certainly on par with the lower White Zetsu."
Nodding in satisfaction, Shūichi deactivated the technique.
This time, he had used only his own chakra, as his chakra level had already reached the level of a Tailed Beast, eliminating the need for Yin Seal support.
The drawback was that, once activated, the technique's healing became uncontrollable.
Even minor injuries would trigger rapid cell division and accelerated healing, risking overuse.
This technique's effect was similar to Tsunade's original Creation Rebirth.
"I'll call it Creation Rebirth, then!"
Not putting much thought into naming, Shūichi began drafting the technique on a blank scroll. He intended to give this to Tsunade.
However, he added the Hundred Healings technique to the scroll's formula.
This was not just because Tsunade and others lacked sufficient chakra; even Shūichi himself would combine it with the Yin Seal in future use.
Once he finished writing the formula, Shūichi paused and continued writing down his future thoughts and directions for the technique.
The healing effect of Creation Rebirth was beyond question, but Shūichi saw some shortcomings.
First, it only worked on himself.
Second, it lacked control.
Moving forward, Shūichi aimed to enhance cell vitality—or, rather, the power of Yang Release—to reach or even surpass Hashirama's level.
Second, he wanted to study Asuka's cells to refine Creation Rebirth, making it controllable and allowing it to heal others.
Finally, he hoped to make these enhancements permanent, forming a bloodline limit.
After finishing, another thought struck him: "Making these effects permanent is actually achievable for me since my body is already as strong as a Tailed Beast, with Yang Release properties meeting the requirements for self-healing without seals."
"It's Tsunade and the others who would struggle. Both Tsunade and the director have sufficient talent, with mastery over the Hundred Healings Technique and the Yin Seal, so they can use Creation Rebirth without issue, but solidifying it as a bloodline would be out of their reach."
"Then there's Shizune. She doesn't have Tsunade or the director's talent. Forget about solidifying it; I'm not even sure if she can master it."
"To enhance their physical capabilities without transplanting Hashirama's cells, there may only be one path left."
The Bijuu Sealing mark!
Or, in other words, Sage Transformation!
The fire-based enhancement he named Bijuu Sealing mark might need a different name if adapted to boost cell vitality.
"Combining the Natural Curse Mark, Hundred Healings, Yin Seal, and Creation Rebirth…"
As he pondered, Shūichi stored the scroll for Creation Rebirth and pulled out another blank scroll to start writing.
He'd only spent three minutes on Creation Rebirth, so the remaining three minutes didn't allow him to reach his ideal goal with the Bijuu Sealing mark, but it was progress.
He had managed to outline a basic formula.
Quickly, he completed the formula.
Shūichi then laid the scroll out on the floor and sat in the center of the formula.
With a clap of his hands, Shūichi closed his eyes, bringing his focus to its peak, and then activated the formula on the scroll.
The next moment, Shūichi felt an immense flow of natural energy surging into his body, merging with every cell, transforming into a powerful life force that rapidly boosted his cell activity—surpassing the effects of Creation Rebirth in an instant, reaching four times his usual baseline!
Moreover, he sensed a substantial increase in his strength, physical resilience, and reaction speed.
This far outperformed Creation Rebirth in that regard.
The Amplification of Yang Release!
However, this formula lacked the ability to store natural energy.
But Shūichi was confident that he could merge it with the Bijuu Sealing mark.
Disabling the technique, Shūichi stood and stored the scroll. "Still needs a step-by-step refinement."
"But I should also try out Sage Mode myself."
Putting the scroll away, Shūichi stood in the center of his study, closed his eyes, and easily sensed the vast natural energy all around him.
Immediately, he began to absorb a large amount of natural energy, combining it with his own spiritual and physical energy in a 1:1:1 ratio, refining it into Sage Chakra.
Sage Mode, activated in an instant!
Opening his eyes, Shūichi picked up a mirror to check, and sure enough, there was no sage mark on his face.
His chakra control was so refined that the Sage Chakra caused no visible effects on his body.
Just as he could fully activate the Hundred Healings Technique without developing curse mark patterns on his skin, Shūichi noted with satisfaction, "From an enhancement standpoint, Sage Mode is undoubtedly superior to the Bijuu Sealing mark."
"Especially in sensory range—it surpasses my Listening technique, and combining them makes it even more remarkable, not only broadening the perception field but also making it more precise."
"However, Sage Mode relies on absorbing natural energy in one go to refine it into Sage Chakra, and once it's exhausted, I have to reabsorb, which can be dangerous during combat."
"The Bijuu Sealing mark, however, can store natural energy and sustain itself continuously."
"When using Fire Release Chakra Mode, Blaze Release Chakra Mode, or Lava Release kekkei genkai, the Bijuu Sealing mark still outperforms Sage Mode."
Of course, for Shūichi, the two techniques didn't conflict.
"So, I should keep optimizing the Bijuu Sealing mark to enhance it comprehensively, making it comparable to Sage Mode. This way, it would be like Sage Mode in curse-mark form, allowing me to maintain it for extended periods—up until my own stamina is depleted."
With that in mind, Shūichi gathered his things and used the Flying Thunder God Technique to teleport directly to the research base.
In an office at that moment, Tsunade was frowning as she examined recent experimental data.
Shūichi stepped forward and handed her a scroll.
Tsunade looked up, frowning. "What's this?"
Shūichi grinned. "An S-rank medical ninjutsu—completed!"
Tsunade froze, then exclaimed in shock, "How… is that possible?"
"How did you finish so quickly?"
Shūichi raised his chin smugly. "Now you see how amazing I am?"
"Take a look. Paired with the Yin Seal and the Hundred Healings Technique, you shouldn't have any trouble using it."
"Of course, it's not perfect yet; once activated, the self-healing is uncontrollable."
Tsunade hurriedly took the scroll, and as she reviewed it, her shock only grew. "You… you really managed to pull it off."
"But you just said yesterday that you still had a bit left to complete."
Shūichi nodded, "I did. So today, I completed that bit."
Tsunade gave him an exasperated look, then blinked in surprise. "It requires only one hand seal?"
Shūichi chuckled, "That seal is for your use."
Tsunade clenched her fist, tempted to punch him. "You really have a way of getting on my nerves with that attitude."
Shūichi sighed, "One must recognize reality; certain gaps are inevitable."
Tsunade gritted her teeth, resisting the urge to throw a punch.
After nearly half an hour, Tsunade finally put down the scroll. "It's extremely well-crafted and more than enough for our use."
With that, Tsunade stood up. Instantly, the Yin Seal symbol on her forehead lit up, followed by the Hundred Healings Technique's curse markings spreading across her body, and she formed the hand seal.
Ninja Art: Creation Rebirth!
"The vitality is on par with White Zetsu cells, though it still falls short of my grandfather's cells, but it's enough to handle most injuries," Tsunade observed.
Shūichi replied, "Our research still has to continue, like making this technique usable on others."
"And also, finding a way to control self-healing."
The first part, in fact, he had a rough solution for: merging it with the Yang Release natural energy amplification formula he had recently completed.
Clearly, the curse mark is best suited for those close to me.
Tsunade nodded and, after deactivating the jutsu, asked, "Do you have any ideas on solidifying cellular activation?"
Shūichi replied, "Once Yang Release's nature transformation is strong enough, it can be solidified, but it also requires sufficient energy, meaning a strong enough physique and chakra reserves."
Tsunade understood instantly. "Yes, that makes sense."
Shūichi added, "Of course, there's one more way."
"You must know about Sage Mode, right, Tsunade?"
She nodded. "Of course."
"Shikkotsu Forest has a Sage Art inheritance, but I never mastered it."
Mentioning Shikkotsu Forest, Tsunade continued, "Shūichi, you should make time to form a summoning contract with Shikkotsu Forest."
Shūichi thought for a moment, then replied, "It's better if Shizune and Asuka handle that."
"I'll focus on combat, and you all can handle the healing."
Tsunade didn't insist and nodded in agreement. "That works."
Shūichi steered the conversation back. "You already know about the Bijuu Sealing mark. I've managed to develop a new jutsu formula that can further amplify Yang Release."
"We could use the Hundred Healings Technique to link the Yin Seal and curse mark, solidifying cell activation—essentially enhancing your current state with my curse mark."
"Though it may not reach the full level of Creation Rebirth, the effect will still be impressive."
Currently, Tsunade's chakra is subtly nurturing her cells to slow down aging and maintain her physical state.
"Is that so?"
Tsunade was intrigued. "With that curse mark's amplification, the effect should be promising. When do you think you can finish developing it?"
Shūichi felt a bit speechless.
When it comes to beauty and youth, women seem to have zero resistance—especially older ones!
Of course, he dared not voice this thought, lest he get punched.
"It shouldn't be too difficult," he assured, then promised, "After New Year's, definitely before my birthday."
"Speaking of which, Tsunade, what do you plan to get me for my birthday?"
Tsunade's expression shifted instantly. "Why would I get you a gift?"
Shūichi pouted, "Stingy!"
She glanced at the necklace Shūichi wore.
That necklace was her most cherished possession, and this brat was still so greedy!
Birthdays weren't that important for a shinobi, anyway.
"Tsunade, you have hemophobia, don't you?"
Shūichi suddenly asked.
Tsunade replied, "Did Shizune tell you?"
Shūichi shook his head. "Just a guess."
"That's probably why you've avoided the battlefield, unable to even work as a medical ninja in the Konoha Hospital or on the frontlines."
Tsunade remained silent.
Shūichi continued, "I might have a way to cure you."
Tsunade raised an eyebrow. "What method?"
"It's not a physical condition, after all."
Shūichi nodded. "I know that, of course. As for the method, I'll keep it under wraps for now—saying it out loud might lessen its impact."
"All you have to do is decide whether or not to let me try."
Tsunade was quiet for a moment before saying, "If you want to try, go ahead. Just don't get your hopes up."
Shūichi grinned. "Don't worry; I'm not that fragile."
"Alright then, it's decided."
The last day of Konoha Year 45.
On a cliff, after an intense sparring session, Shūichi and Kakashi sat side-by-side on the ground, watching the sunset.
Not far away, under a waterfall created by Shūichi, Guy was training hard, wielding nunchaku and shouting passionately.
"Shūichi, do you have any advice on my training direction?" Kakashi asked after catching his breath.
Shūichi drained his salty glucose water and replied, "Your Lightning Style skills are already exceptional in the shinobi world. With Chidori, Chidori Current, Raikiri, and the Hatake swordsmanship, you have a very solid combat framework."
Kakashi nodded.
Shūichi continued, "You clearly have talent in Lightning Release. Since you've mastered Chidori and Raikiri, you can develop other Lightning Style techniques tailored to you to diversify your offensive and defensive options."
"Of course, that's secondary and won't increase your maximum combat power."
"Kakashi, you know about my Fire Release Chakra Mode, right? And how the Cloud ninjas have their Lightning Release Chakra Mode. The way I raised my power ceiling was through the Fire Release Chakra Mode."
"So, are you suggesting I train in the Lightning Release Chakra Mode?" Kakashi asked.
Shūichi grinned. "Kakashi, do you know what my first hurdle was when training in the Fire Release Chakra Mode?"
Kakashi thought it over. "Both Fire and Lightning Release are notoriously hard to control. Actually, Fire Release is likely harder, requiring immense chakra control, even for a medical ninja."
Shūichi shook his head. "No."
"It was chakra quantity."
Kakashi was taken aback. "That… how is that possible?"
He remembered Shūichi's chakra being almost terrifyingly vast.
Shūichi smiled. "I didn't start with such massive chakra reserves."
He tapped the blue mark glowing on his forehead, indicating the Yin Seal mark. "I learned this sealing technique from Lady Tsunade, specifically for chakra storage."
"Of course, the chakra control issue you mentioned was also a challenge."
"So, Lady Tsunade and I collaborated on the development of the Hundred Healings Technique, specifically to support chakra distribution and control."
"Only then did I manage to create the Fire Release Chakra Mode."
Kakashi couldn't help but be impressed. "I see… all that effort behind the scenes is truly admirable."
Shūichi nodded—he might have certain advantages, but he certainly worked hard too!
"Take the Fourth Raikage, for example. His chakra reserves are at Tailed Beast levels."
"That's one foundation of his Lightning Release Chakra Mode's power. The other is his physical strength, which can withstand the destructive nature of Lightning Release."
Kakashi nodded in agreement, having experienced how cellular activation can boost reaction time through his Chidori Current.
Shūichi continued, "The Raikage's Lightning Release Chakra Mode is only B-rank in difficulty. With your knowledge of Lightning Release and chakra control, it wouldn't be a problem for you."
"But right now, you lack the physical durability to endure that kind of energy. It would take a decade of gradual training, and that's assuming you have enough chakra to sustain it."
"I once considered training in the Lightning Release Chakra Mode but gave it up due to physical limitations. So instead, I developed Chidori Body Flicker based on your Chidori."
Standing up, Shūichi activated the Chidori technique, lightning enveloping his limbs and then spreading across his entire body.
"I created this movement technique to compensate for my lack of attack speed," he explained to Kakashi. "My neural response speed is high, but my limbs couldn't keep up, so with Chidori Body Flicker, I can quicken my reflexes without affecting my ability to use other jutsu."
Kakashi listened thoughtfully.
He knew Shūichi wasn't boasting about his achievements but showing him a path to growth.
"Of course, now that I've grown stronger, I can use the Lightning Release Chakra Mode as well," Shūichi said as he activated it. Lightning chakra flooded his body, forming an armor-like layer, flickering with electricity.
With his current physical prowess, he no longer needed years of training to handle it.
"Incredible chakra!" Kakashi was still awestruck seeing the Lightning Release Chakra Mode for the second time.
Shūichi deactivated it and smiled. "Kakashi, with your current physique and chakra, a technique-centered approach suits you best."
"Your swordsmanship combined with Lightning Release will be potent. At the very least, it won't be any weaker than Sakumo-senpai's. I'm confident of that."
"Regarding the direction of Lightning Release in the shinobi world, the Lightning Release Chakra Mode is probably the pinnacle."
But clearly, the path wasn't feasible for Kakashi due to his limited chakra reserves.
While having vast chakra didn't necessarily make someone a strong ninja, it was still a foundational asset for achieving strength.
Kakashi understood this deeply now, especially seeing how Shūichi's abilities were all built upon his large chakra reserves.
Shūichi added, "By the way, combining Lightning Release with Flying Thunder God would be an excellent option."
"Lightning Release's cellular activation will improve your reaction time, making it easier to use Flying Thunder God."
Kakashi nodded, now considering training in the Flying Thunder God Technique.
"As for your chakra issue… I might have a solution," Shūichi said with a smile.
Kakashi looked at him, surprised. "Besides the Yin Seal, is there another way?"
"One word," Shūichi said slowly. "Tailed Beast."
Kakashi's eyes narrowed. "You mean the one inside Rin?"
Shūichi nodded. "I'm not suggesting you become a Jinchūriki."
"Rather, I propose that you acquire a portion of the Tailed Beast's chakra. While it wouldn't be as potent as a true Jinchūriki, it could significantly boost your chakra."
"But, of course, this approach is very risky. Tailed Beast chakra isn't easy to control. One mistake, and you might be consumed by the Tailed Beast's malice and go berserk."
Kakashi was silent for a moment, then looked up at Shūichi with firm resolve. "Shūichi, I'm willing to take that risk!"
Shūichi shook his head. "There's no need to rush your decision. Consult with Minato-sensei first."
Kakashi immediately agreed.
Shūichi smiled again. "Kakashi, don't let your talent go to waste."
"Apart from Lightning Release, you should master other jutsu as well. That way, you can handle any situation and won't be easily countered by an enemy."
"Mastery and focus, then breadth and refinement."
This was Shūichi's own philosophy.
Of course, it was also a path that only a true genius could follow.
...
The Last Day of Konoha Year 45 Passes, and the New Year Begins
On the second day of the New Year, Shūichi visited the orphanage with Nonō Yakushi and Asuka. Due to the ongoing war, many new orphans had arrived there—some were the children of Konoha ninjas who had fallen, while others had lost their families due to the ravages of war.
After three days at the orphanage and another two days visiting his seniors for New Year's greetings, Shūichi finally arrived at the research base on January 7th, Konoha Year 46.
And there he found Tsunade, fast asleep, drooling.
Tsk!
What kind of daydreaming was this?
Shūichi approached, studying her intently. This was a rare opportunity.
Tsunade, don't blame me for taking advantage of the situation!
He cast a genjutsu.
Demonic Realm – Palace of Memories!
...
It was unclear how much time had passed before Tsunade slowly woke up, only to find Shūichi across from her, smirking.
She quickly wiped her mouth, feigning nonchalance. "When did you get here, you rascal?"
"Been here a while," Shūichi replied with a playful smile. "You looked like you were having a nice dream. Was it a good one?"
"Did it have me in it?" he teased.
Tsunade rolled her eyes, scoffing, "Brat!"
Ugh!!!
Fine, not going to embarrass myself further. Just wait till I'm older...
Shūichi changed the subject, "Tsunade, starting today, I'll begin researching Asuka's cells."
"Regarding the First Hokage's cells, I need you to continue your work. One application we're exploring is merging them with White Zetsu's cells to try and cultivate targeted growth. I'll get Hayate's consent to use his cells to see if we can grow a pair of lungs for transplant, which might alleviate his Kekkei Genkai disease."
Tsunade quickly entered research mode, nodding. "That's the plan, then!"
As time passed...
In June of Konoha Year 46, Konoha, the Sand Village, and Iwa reached an initial ceasefire agreement. Konoha would return the Four-Tails, while the Sand and Iwa would divide the resources of Land of Bird.
In August, Shūichi extracted the Four-Tails' chakra and returned half of it to Iwa.
By September of the same year, the One-Tail was prematurely returned to the Sand Village.
However, the war across the shinobi world was far from over.
Mist Shinobi continued their assaults along the coast of the Land of Fire, while the Cloud ninjas fought battles against Iwa and Konoha alike.
Finally, in December, Tsunade's research on the cells of the First Hokage made a breakthrough. By combining Hayate's cells with White Zetsu's and the First's cells, they successfully cultivated a pair of lungs.
Just before the New Year, the surgery succeeded, giving Hayate a new lease on life. Although his Kekkei Genkai disease couldn't be cured completely, the First's cells in his new lungs would stave off the illness's encroachment for a time.
Based on their month-long observation, they estimated the lungs would remain effective for over ten years before signs of fibrosis might reappear.
March 18, Konoha Year 47 – Kakashi's Tailed Beast Experiment at the Lab
"Isn't this his first live experiment? Is it a bit premature?" Tsunade asked with a frown. "Kakashi's body is still maturing."
Shūichi smiled. "It's not the first, actually."
"To be precise, this is the third."
"The first was Kinkaku and Ginkaku of the Cloud Village. They gained Nine-Tails chakra after consuming parts of its flesh."
"The second was me. After eating part of the Four-Tails' flesh, I acquired Four-Tails chakra and gained the Lava Release."
Tsunade shook her head, "But Kakashi is different from you. You have the strength to suppress the Tailed Beast's power."
Shūichi looked at Kakashi in the lab, preparing for the procedure. "Don't underestimate Kakashi, Tsunade. He's also mastered sealing techniques."
"Besides, I've had him experience Tailed Beast chakra several times before this, exposing him to its malevolent intent so he could learn to counter it."
"This experiment wasn't started on a whim."
Tsunade stopped objecting and asked instead, "If Kakashi succeeds, will he be the first?"
Shūichi nodded. "Indeed. But it's foreseeable that very few will ever be able to control Tailed Beast chakra."
Soon, the preparations were complete.
Kakashi sat in the center of a sealing formation, and a shadow clone of Shūichi handed him a tray holding slices of the Eight-Tails' horn.
This had been cultivated for the experiment.
Under Shūichi and Tsunade's watchful eyes, Kakashi began eating the slices, one by one.
Soon, red Tailed Beast chakra surged around him.
"What powerful chakra!" Tsunade gasped, "And it's incredibly violent."
In the lab, Kakashi's body started trembling uncontrollably as the Tailed Beast chakra assaulted him, flooding him with pain. Worse yet, the chakra's malevolence kept bombarding his mind, testing his mental resilience.
Quickly, Kakashi couldn't continue eating and was forced to fully engage with the Eight-Tails' chakra, clashing with its hostile will.
If he succeeded in subduing it, he'd gain control over the Eight-Tails' chakra.
How much he could control would depend on his own constitution.
Inside the lab, Shūichi's shadow clone stood ready. If Kakashi faltered, he'd immediately activate the sealing formation.
As time passed, an hour slipped by. Kakashi's pained expression finally began to soften.
Tsunade sensed it as well. The once-violent Tailed Beast chakra had calmed down. "Did he succeed?"
Shūichi smiled, "It appears so!"
Inside the lab, tails began to materialize behind Kakashi as the Tailed Beast chakra condensed.
One tail… two tails…
Reaching the limit of two-tails!
Shūichi nodded approvingly, "Not bad at all!"
...
Under Tsunade's Witness, the Tailed Beast Weapon Project Achieves Initial Success
As Konoha Year 47 arrived, research on Asuka's cells also reached a breakthrough. Shūichi and Tsunade, working together, managed to fuse the First Hokage's cells with Asuka's by using White Zetsu's cells as a buffer. This reduced the hyperactive nature of the First's cells without diminishing their Yang Release capabilities.
This development confirmed Shūichi's prior hypothesis: the First's cells and Asuka's cells could indeed complement each other.
...
By the end of Konoha Year 47, after repeated persuasion from Shūichi, Tsunade finally agreed to undergo a transplant of the fused cells from the First and Asuka. When she awoke from the procedure, it was already Konoha Year 48, and Shūichi shared some unexpected news:
Kushina Uzumaki was pregnant!
On this day, Jiraiya returned to Konoha and invited Tsunade out for a drink. When they arrived at the tavern, she was surprised to find Orochimaru there as well.
"Tsunade, I see... Looks like Shūichi-kun's research has made great strides recently," Orochimaru remarked with a knowing smile.
He could see the difference in her right away.
He was far too familiar with the power of the First Hokage's cells.
Tsunade sat down, grabbing Orochimaru's untouched cup and downing it. "You're becoming less human yourself, Orochimaru."
Orochimaru merely smirked.
Then Tsunade turned to Jiraiya, who seemed a bit down. "Hey, what's wrong with you?"
Jiraiya took a sip, sighing. "I heard... the three kids I trained back then—apparently, they're dead."
Tsunade blinked in surprise. "You mean those three from the Land of Rain?"
She scoffed slightly, "Wasn't that bound to happen?"
"They became ninja; it was only a matter of time before someone killed them."
Jiraiya was indignant, "Hey, Tsunade, I'm grieving here! You could at least comfort me a little—a hug, maybe?"
Tsunade rolled her eyes. "You never should have stayed to teach them ninjutsu in the first place."
"Trying to end wars through peaceful means—too naïve!"
"Instead of moping, maybe you should focus more on Minato. Kushina is pregnant."
She then looked at Orochimaru. "Seems like Minato is about to surpass you in your little rivalry."
Orochimaru chuckled mildly. "A bit embarrassing to be bested by a younger generation, but if it leads to change, it's worth it."
Tsunade, recalling what she'd heard from Shūichi, added, "Just be wary of Danzo. He has plenty of leverage against you."
Orochimaru gave a sly grin. "Tsunade, you and Shūichi-kun seem more in sync than ever."
Jiraiya perked up in shock. "Tsunade, you haven't started pursuing younger boys, have you?"
Humiliated, Tsunade's fury burst forth. "Go to hell!"
Boom!
Jiraiya was sent flying, crashing through the tavern wall and disappearing from sight.
With a deadly glare, Tsunade turned to the grinning Orochimaru. "Don't look at me like that. It's disgusting!"
"Oh, but Shūichi-kun is already 15, you know."
Before Tsunade could retort, Orochimaru vanished.
Meanwhile, Jiraiya, stuck in the shattered wall, coughed up blood. "Four ribs broken... Tsunade's gotten even stronger; a single strike…"
By the time he pulled himself free and reentered the tavern, Tsunade had already finished her drink and left without paying.
"Honestly… terrible friends…"
Seeing the server waiting for him to cover the tab, Jiraiya was despondent. Seeking comfort only to get beaten up and saddled with the bill…
After paying, Jiraiya stepped outside and sighed.
Nagato and the others were dead. Even the wielder of the Rinnegan... not fated to change things?
...
Konoha Year 48, October 10
As Tsunade worked at the research base, she suddenly looked up. "What's going on?"
The ground was trembling violently.
"Wait…"
Her expression changed, and using the Body Flicker Technique, she appeared outside the base, where she spotted an enormous creature in Konoha's core.
"That's…"
"The Nine-Tails!"
Her heart skipped a beat, and she immediately rushed toward the battle.
Halfway there, her pace slowed.
"Lady Tsunade!"
Shizune came sprinting toward her, holding a person covered in blood. "Please, Lady Tsunade, we have to transplant the First's cells into Shūichi… he…"
Her voice broke, and tears streamed down her face.
Tsunade froze, staring at the person in Shizune's arms—Shūichi Hoshita, his chest pierced through, arms gone, blood everywhere.
Even the necklace she'd given him was stained red.
"No… how can this be?"
"He has Creation Rebirth…"
Her entire body shook with terror as memories of her dead lover, Dan, and her brother's broken body flashed in her mind.
"Lady Tsunade!"
"You're the only one who can save him now!"
Shizune was sobbing. "Shūichi was critically injured by a space-time jutsu…"
"I…"
Tsunade took a shaky step forward, reaching out.
Blood from Shūichi's severed arm dripped onto her hand.
It was still warm.
A shudder ran through her. "Damn it…"
Tsunade, you're the most powerful medical ninja in Konoha.
You're a Senju…
Clenching her teeth, she took Shūichi from Shizune's arms.
Shūichi's eyes fluttered open, and he gave her a faint smile. "Tsunade… looks like I can't keep my promise to protect you all forever."
"Please… take care of Nonō, Asuka, and Pakura for me…"
Tsunade choked back tears, snapping, "Take care of your own lovers yourself!"
"And don't think I'm going to let you die!"
"I'm Tsunade, the world's best medical ninja!"
Without another word, she carried him at full speed back to the lab. Her poise and confidence returned as she directed Shizune to assist with the First Hokage cell transplant procedure.
Once the operation was complete and Shūichi's life was saved, Tsunade received the tragic news from Jiraiya:
The Third Hokage had died.
He'd used the Reaper Death Seal to contain the Nine-Tails.
Three days later, Minato Namikaze would be inaugurated as the Fourth Hokage.
After hearing Jiraiya's words, Tsunade fell silent. A moment later, she finally replied, "Being Hokage often leads to this kind of fate—it's something you get used to."
"Who was the enemy?"
Jiraiya responded, "The mysterious person who previously took Uchiha Obito, suspected to be Uchiha Madara!"
Tsunade's gaze sharpened. "Jiraiya, stop chasing after that elusive 'destiny' of yours. Just stay focused. That guy will show up again."
She paused and added, "And when he does, don't let it end up costing the Fourth as well…"
With that, Tsunade turned and waved him off, saying, "I understand. I'll be there when the time comes. Right now, I need to rest."
Entering her quarters, Tsunade quickly drifted into a deep sleep, finally free of the weight she'd been carrying.
...
Inside the illusion, years passed, but in reality, only a few minutes had gone by.
Her eyelids trembled, and Tsunade slowly opened her eyes, still drowsy and drooling a bit—only to find a smiling face right in front of her.
"Shūichi?"
"What are you doing here…?"
Tsunade murmured, still half-asleep. But then she snapped to attention, startled. "Your body hasn't fully recovered yet—why are you wandering around…"
She cut herself off mid-sentence, realizing something was wrong.
The boy in front of her looked taller and older than she remembered, and this wasn't her resting room!
Focusing on Shūichi Hoshita, Tsunade's eyes narrowed. "That was… an illusion, wasn't it?"
Shūichi blinked innocently. "Tsunade, what are you talking about?"
"Did you have a dream? I could hear you calling my name nonstop!"
Tsunade blushed, gritting her teeth. "It's definitely because of something you did, you little rascal… You're dead meat!"
With a kick, she smashed a large crater into the ground.
Shūichi jumped back, startled. "Hold on! This is the research base!"
"And don't you want to check if your hemophobia is really gone?"
Tsunade stopped in her tracks, frowning as she recalled the dreamlike scenario she'd just experienced.
Shūichi took out a kunai, made a small cut on his hand, and flicked droplets of blood toward her before it healed.
Tsunade instinctively dodged, but to her surprise, she felt no symptoms of hemophobia.
As the wound closed, Shūichi grinned. "Seems like you're cured."
"Good thing it was a psychological issue, huh?"
The method he'd used was certainly targeted for her specific problem.
If it had been physiological, he clearly wouldn't have taken such a risky approach.
As Tsunade landed, she hesitated, frowning. "Your genjutsu… I didn't detect any flaws at all. How did you pull that off?"
Shūichi grinned mysteriously. "That's classified."
There was no way he was going to admit to her that he'd set up a scenario in the genjutsu that involved role-playing. If he did, she'd probably chase him through three districts. The consequences would be… severe.
"Well, now that you're healed, I'll get back to my work."
With a casual wave, Shūichi vanished.
Tsunade opened her mouth to call after him, but stopped herself.
The illusion had felt too real, and since she couldn't pinpoint the mechanics of Shūichi's technique, she couldn't dismiss the idea that it might have tapped into some deeper reflections within her mind.
...
In another lab, Shūichi didn't immediately get back to work. Instead, his attention turned to his Tag Tree.
A new tag had just arrived.
Tag: [PUA Expert]
Requirement: Successfully PUA at least three people.
Effect: Talk no Jutsu effectiveness +100%, Mental Willpower +100%.
Looking at the new tag, Shūichi's expression instantly changed.
This was slander!
Libel!
The Tag Tree was making outrageous accusations!
All he'd done was cure Tsunade's phobia and help Pakura avoid being consumed by hatred, and now it labeled him a "PUA." Too much!
Although… the boost to persuasion skills and the doubled mental resilience were admittedly tempting.
"Guess I need to PUA three targets to fully activate it…"
Sighing inwardly, Shūichi focused himself again, shaking his head. "The Tag Tree's turning me into more of a freak every day…"
"Better focus on research and training…"
Refocusing, he retrieved a sample of Asuka's blood he'd prepared earlier and began his study.
...
Meanwhile, in his usual training ground, Shūichi's Shadow Clone was practicing Magnet Release when Kakashi approached him.
"Shūichi, I've decided to start training in the Flying Thunder God Technique. Do you have any tips?"
"Minato-sensei said you mastered it in under six months—faster than he did."
Shūichi opened his eyes and smiled. "It's true I mastered it in under six months, but what Minato-sensei probably didn't mention is that I was already skilled in sealing techniques, along with several other space-time ninjutsu."
"Also, I had solid grasp of sensory ninjutsu—those were all part of my preparation."
Kakashi nodded. "I see. No wonder Minato-sensei told me to ask you—he must have known your background."
"By the way, Shūichi, about the Tailed Beast Chakra—I've decided to give it a try."
Shūichi nodded thoughtfully. "I'll report this to the Third Hokage. When everything's ready, I'll reach out to you."
"Understood. I'll head out, then."
With that, Kakashi departed.
Watching Kakashi leave, Shūichi thought to himself, Kakashi should be able to master the Flying Thunder God Technique, but reaching the level where he can use it as seamlessly in battle as Minato-sensei and I… that'll be tough.
Even with his Lightning Blade technique, Kakashi's reflexes might not be fast enough.
That said, the Flying Thunder God would still be useful for him.
After all, it's a space-time ninjutsu!
And as for the Tailed Beast Chakra… Shūichi was curious to see how far Kakashi could go without the Sharingan.
Would he still live up to his reputation as "Copy Ninja Kakashi," the legendary "Kakashi of the Sharingan"?
…
A full day went by in the blink of an eye.
After receiving the feedback from his shadow clone, Shūichi finished his daily training and headed to the Hokage's office. Even though he had the authority to proceed with the tailed beast experiment on his own, it was still necessary to inform the Hokage formally.
Once he left the Hokage Building, Shūichi sent a shadow clone to Kakashi's place while he returned home.
In the kitchen, Asuka was already preparing dinner. After freshening up, Shūichi entered the kitchen, where Asuka looked at him with a hint of frustration. "Shūichi, it's so hard to improve the Adamantine Sealing Chains; I can't find any breakthroughs at all!"
Shūichi had previously suggested that she integrate the power to seal souls into her Adamantine Sealing Chains. Unfortunately, he had overestimated Asuka's ability; several days had passed, and she still hadn't found any progress.
Seeing her struggling expression, Shūichi smiled and said, "If that's the case, I'll develop a separate sealing technique for binding souls first. Once you've mastered it, then you can try integrating it into your Adamantine Sealing Chains."
Asuka's eyes lit up at the idea, nodding eagerly. "That could work! Thanks, Shūichi!"
At that moment, Nonō Yakushi's voice called out, "Asuka, that's not the right mindset for training!"
"You're depending too much on Shūichi."
Hearing this, Asuka stuck her tongue out playfully, quickly replying, "It's just that I'm not very good at it, Nonō-senpai!"
Nonō entered the kitchen, shooed Shūichi out of the way, and joined Asuka in preparing dinner. Shūichi lingered at the kitchen door, watching the two busy themselves while they chatted casually.
After dinner, he left a shadow clone in the study to continue working while he himself used the Flying Thunder God technique to teleport to a research base near the Land of Fire's Daimyo's palace.
When Shūichi arrived, Pakura promptly reported, "Lord Shūichi, the ninja selected by the Daimyo has arrived. Do you want to meet them?"
"Will send a shadow clone; we'll continue with our training."
Shūichi sent a clone to handle the matter and joined Pakura in the training room. They sat facing each other, holding hands, their chakras linked together. Shūichi was using a mind-link technique to help him understand the secrets of Pakura's Scorch Release.
It wasn't the first time he'd trained this way with Pakura, but this was the first session since unlocking the "Prodigy" Tag, and the efficiency had noticeably increased.
Before they knew it, it was nearly 10 p.m. Reluctantly ending the training, Shūichi said to Pakura, "Your chakra reserves may not be high, but with the help of the Bijuu Sealing Mark, you'll have enough to sustain the Scorch Release Chakra Mode."
"From now on, focus all your efforts on mastering this mode to maximize your Scorch Release power and enhance your combat effectiveness."
Pakura nodded. "Rest assured, Lord Shūichi. I'll do my best."
Shūichi couldn't resist throwing in a little PUA technique: "If you don't give it your all, I'll end up leaving you far behind."
"You don't want to become an irrelevant subordinate, do you?"
Pakura's expression turned resolute. "I won't disappoint you, Lord Shūichi. I will master the Scorch Release Chakra Mode!"
Satisfied, Shūichi nodded. "My Fire Release Chakra Mode incorporates Wind Release, so it should serve as a good reference for you."
"Additionally, I'll teach you several techniques: Fire Clone, Lotus Inferno, Flame Dragon Breath, and the Fiery Lotus Steps. When performed with Scorch Release, they'll be even more powerful. Scorch Release's properties should also enable you to fly once you master its chakra mode. The Fiery Lotus Steps will enhance your speed and agility in the air."
Though difficult to master, these techniques would be easier with a Kekkei Genkai.
Pakura, eager for the new jutsu, promised, "I won't let you down, Lord Shūichi!"
"I'll be watching."
With that, Shūichi vanished.
---
The following day…
Shūichi brought Kakashi to the experimental base.
Seeing Kakashi, Tsunade blinked in surprise. "Is this for the tailed beast experiment?"
Shūichi nodded. "Yes. We'll begin by letting Kakashi gradually acclimate to the tailed beast's chakra."
Tsunade, recalling the experience from the Genjutsu world, merely nodded. "Be careful. Take it slow; don't rush things."
Shūichi grinned. "Relax, Tsunade. I'm not one to rush."
Tsunade nodded and walked away.
Kakashi, however, looked intrigued. "Shūichi… you and Lady Tsunade…?"
Shūichi tilted his head with a grin. "Kakashi, what do you think about me courting Tsunade?"
Despite his suspicions, hearing Shūichi say it so bluntly left Kakashi momentarily speechless.
"You idiot! Do you have a death wish?" Tsunade's voice suddenly echoed.
Shūichi instantly grabbed Kakashi, and they teleported into a room shielded by seals and barriers.
Kakashi, finally composed, chuckled. "You're really something, Shūichi. Bold, to say the least."
Shūichi scoffed. "Kakashi, this is a trait you should learn from me. If you like someone, be bold about it! Only by facing your desires head-on can you avoid being controlled by them."
"This also applies to facing tailed beast chakra. The so-called malice of a tailed beast is nothing more than an intensification of negative emotions."
Kakashi listened intently as Shūichi's expression grew more serious. "Everyone has desires, both good and bad."
"No matter how righteous or optimistic someone is, they always carry some negativity deep inside. The tailed beast chakra's malice amplifies these negative parts."
"So first, you must confront this, or even if your body endures, you'll lose your mind to it and be unable to control the tailed beast's power."
"Human desire must be controlled; if left unchecked, it'll overwhelm you. But suppressing it constantly only makes the backlash stronger."
"Face it. Control it. Direct it. Dissolve it. Master it…"
Shūichi paused, then continued, "A ninja's chakra combines both spiritual and physical energy. Its strength depends not only on your body but also here—" he pointed to his head, "—and here." He pointed to Kakashi's heart.
"Spirit and mind."
"Your thoughts and your willpower."
Kakashi reflected deeply.
Shūichi added, "Kakashi, if you want to reunite with Obito or protect those you hold dear, you must first strengthen your spirit, your thoughts, and your heart."
"This is essential for breaking through your limits. Otherwise, you'll always be constrained by your body."
From his research, this was the closest he'd come to understanding chakra's relationship with the human body.
"I'll remember that."
Kakashi nodded solemnly. "Thank you, Shūichi."
Shūichi chuckled, "If you want to thank me, be my kid's teacher one day!"
Kakashi readily agreed, "Absolutely."
After a brief pause, he added seriously, "But, with whom will this kid be? Shizune, Lady Tsunade, or Asuka-san?"
Shūichi burst out laughing. "You sly Kakashi! Acting all serious, but secretly you've got jokes! Next time we treat Rin, I'll expose your true self."
"No wonder you wear that mask all the time!"
Kakashi almost rolled his eyes when he heard this.
After some banter, Shuichi had Kakashi sit cross-legged in the center of the formation, then carefully infused a portion of Eight-Tails chakra into Kakashi's body.
The experiment officially began!
However, Shuichi didn't stay for long himself; after three minutes, seeing that Kakashi was still holding on, he left a shadow clone to watch over him and quickly disappeared with the Body Flicker Jutsu.
Meanwhile, at the experimental facility in the Daimyo's compound, Shuichi's shadow clone was also conducting tests.
The Daimyo's selected ninja, however, were clearly no match for Kakashi. Out of the six candidates, not one managed to hold out beyond three minutes before losing control to the Tailed Beast chakra and going berserk.
Shuichi hadn't expected much from them. If Tailed Beast chakra was that easy to master, Jinchuriki would have no use at all.
He swapped in new candidates.
As for the failed subjects, Shuichi didn't return them to the Daimyo. Instead, he kept them as extra hands for Pakura.
Back on Kakashi's side, he endured a solid ten minutes during his first attempt. Each day, Kakashi would test himself once, enduring longer each time. Though it became increasingly difficult, his resilience proved truly extraordinary.
Time passed, and it was already March 4th, Konoha's 46th year, Shuichi Hoshita's 13th birthday.
Since everyone was here, Shuichi held a casual dinner party in his courtyard.
Along with friends like Kakashi, Kurenai, Guy, Shisui, and Sarutobi Shinnosuke, older figures such as Minato Namikaze, Kushina Uzumaki, and even the legendary Sannin were all present.
Of course, Tenka came too.
After giving him her gift, she pulled Shuichi aside to whisper, "My, Shuichi, you've gotten taller again!"
"Oh, and here's some happy news: my elder sister is pregnant!"
Shuichi's face lit up. "Please send my congratulations to your Sister! When the baby arrives, I'll visit to celebrate."
Tenka blinked playfully at Shuichi, "And?"
Shuichi blinked back, "And what?"
She pinched his cheek, "A present, of course! That's going to be your future nephew!"
Putting on a mock-serious look, Shuichi said, "But I'm only thirteen, Tenka-san; you're far too mischievous!"
Tenka laughed, gave him a quick peck on the forehead, and teased, "Oh, you're spoken for already, Shuichi-kun. A genius like you won't slip through my fingers. The kids we'd have are sure to be prodigies!"
Shuichi widened his eyes, "Tenka-san, that's heartbreaking; am I only good enough for the children?"
She laughed again, "It's also because you're amazing, Shuichi."
"And…" she leaned closer, whispering in his ear, her breath warm against his skin, "I won't force you to make it official, either."
"So, grow up soon; I'll be waiting!"
Despicable! Seducing a thirteen-year-old boy? Far too mischievous!
Shuichi decided he'd have to rein her in someday, firmly disciplining her to keep her out of trouble. But for now…
With a raised chin, he declared proudly, "Tenka-san, I'm a serious person."
She chuckled and nodded, "Oh yes, Shuichi-kun, a true gentleman—no wonder so many girls adore you."
"Speaking of which," she continued, "When your nephew is born, I'd like you to be his teacher."
Shuichi thoughtfully stroked his chin as though in deep contemplation, then, under her hopeful gaze, nodded slowly. "But only because it's you asking, Tenka-san."
She smiled, her eyes practically sparkling.
…
The dinner was lively and joyful, though a few familiar faces were missing.
Rin Nohara was still bedridden, Obito Uchiha was MIA, and Sarutobi Asuma was stationed in the Daimyo's palace.
At 9 p.m., as the dinner ended, Shuichi saw each guest out one by one.
---
The next day.
In his training ground, Shuichi sat with his hands clasped, eyes lowered in concentration as the wind and fire chakras within him collided and fused repeatedly. Gradually, a new form of power emerged.
A new nature transformation—Scorch Release!
After months of nightly training with Pakura, plus his pre-existing mastery over Wind and Fire, and his simultaneous use of the two chakra natures in his Fire Release Chakra Mode, he had finally mastered it today.
It was the third Kekkei Genkai he could call his own.
Lava Release, Fire Nether Chains, and now Scorch Release!
Rising to his feet, Shuichi's form was soon encased in a blue chakra cloak adorned with delicate purple lotus blossoms.
Slowly, he lifted off the ground.
The Scorch Release Chakra Mode!
Although it resembled his Fire Release Chakra Mode in form, the power within was vastly different.
It was noticeably stronger.
Without the assistance of the Bijuu Sealing Mark, the lotus patterns shone a striking purple.
Furthermore, as Shuichi had previously speculated, this new mode also granted him a limited ability to hover in midair.
However, upon closer inspection, Shuichi realized that the hovering ability was quite slow and not particularly agile.
On the other hand, using Fiery Lotus Steps felt even easier in this mode than in the Fire Release Chakra Mode, with noticeably better results.
"Still, this mode doesn't drastically enhance my combat power."
Shuichi mused, "The power of a jutsu depends on not only nature and shape transformation but most importantly on the chakra output."
"With nature transformation, there's no question. Scorch Release's attack power when using Flame Dragon Breath or Rasenshuriken will definitely surpass the previous combination of Fire and Wind."
"As for shape transformation, this Scorch Release Chakra Mode is more solid than before, but it still doesn't compare to the standard set by Susanoo."
Susanoo was indeed the pinnacle of form, representing an extreme that was hard to rival.
Although size doesn't always equate to strength, something larger is certainly not weak!
"So, I'll still have to try creating a 'Gundam' of sorts."
"It may not be something I rely on, but it's certainly something I need."
"Against something as formidable as Susanoo, matching its power seems like the best way to counter it."
Shuichi had already formulated the next step for his development or, at the very least, the direction to attempt.
If he were to create a 'Gundam,' Scorch Release seemed like a viable foundation for shaping it.
But it wasn't just Scorch Release; Lava Release could also be molded into a 'Gundam.'
In fact, from the perspective of shape transformation, Lava Release might even be better suited.
While combining Wind and Fire makes it easier to mold, it still falls short of Lava Release in terms of structural integrity.
"For defense, Lava Armor definitely outperforms Scorch Chakra Mode. But for offense, Scorch Release has the edge. In terms of raw power, though, Lava Style is superior…"
Shuichi pondered, "And it doesn't seem too challenging to combine Lava and Scorch Release."
His Fire Release Chakra Mode already combined both Fire and Wind, while his Blaze Release Chakra Mode was a blend of Fire and Yin.
Combining two chakra natures was already second nature to him, and handling three would be a manageable challenge.
Quickly forming a plan, Shuichi split into two shadow clones to begin the development immediately.
"Next after Scorch will be Magnet Style—it's almost ready…"
This reminded him of the Eight-Tails' ink.
Could that be categorized under Water Release?
Once he mastered Magnet Style, could he evolve it into Electromagnetic Release by adding an electric charge? Shuichi then recalled possible advanced Kekkei Genkai like Wood Style, Storm Style…
"It's clear I'll need to acquire 'Earth Release Master,' 'Water Release Master,' and 'Lightning Release Master' to build a solid foundation."
Shuichi rubbed his forehead thoughtfully, "An electromagnetic railgun would likely be considered a Kekkei Genkai jutsu, separate from standard Lightning Release."
"For an S-rank Lightning jutsu, Kirin could work, but it's too situational."
"Wait… My thinking doesn't have to be confined to the Shinobi world's concepts; a railgun operates through electromagnetism, while pure Lightning Release generates electric currents and fields…"
Shuichi's eyes brightened. "An electric field!"
"Yes, an electric field!"
"A high-energy particle beam—or, to be precise, a stream of charged particles!"
"Creating this technique could establish a foundation in electric fields, and once I learn Magnet Release from the One-Tail, I can combine it further to master Electromagnetic Release."
A satisfied smile spread across Shuichi's face.
His path with Lightning Release was now clear.
Which left only Water and Earth Release.
S-rank techniques often reach extremes in both nature and shape transformations.
Take Water Release's Severing Wave, for instance, which achieves a high degree of shape transformation. Though not technically S-rank, it approaches that level.
For Earth Release, Ōnoki's Light-Weight Rock Technique exemplifies pure nature transformation.
Though Shuichi had no experience with Light-Weight Rock Technique, from what he understood, they worked by altering an object's density.
Since the affected object didn't change in volume, it was the density that changed.
For Earth Release, nature transformations could also involve hardening or softening.
For example, jutsu that harden the terrain, or softening jutsu like Swamp of the Underworld or clay-based techniques.
"For Water Release transformations… I need to broaden my thinking. Water Release isn't limited to just water; it encompasses liquids in general."
"If the Eight-Tails' ink isn't a Kekkei Genkai, it's Water Release."
With his eyes closed, Shuichi dove into his memory, extracting every bit of useful knowledge.
Soon, he had new ideas.
Heavy Water!
A dense variant of water, in which neither plants nor animals could survive.
Royal Water!
A highly corrosive yellow liquid that could dissolve metals like titanium and gold.
Shuichi recalled the production process of the former but couldn't fully remember the latter, so he'd need to conduct some tests.
Once he analyzed each substance and understood its nature, he'd be able to recreate them through chakra-based transformations.
Both of these would be far more potent than regular water.
As for Earth Release—
In terms of hardness, the first thing that came to mind was the hardest natural stone: diamond!
Diamond was even harder than steel.
"If my nature transformation goal is hardness, diamond would be the ultimate choice."
With his thoughts expanded, Shuichi saw the possibilities open up, realizing diamond's remarkable characteristics.
Its extreme hardness, high melting point, and non-conductivity were all major advantages.
The fact that it didn't conduct electricity could even counter the idea that Lightning Release always trumps Earth Release.
So really, all these supposed "counters" balance each other out!
Having determined various directions, Shuichi entered another busy phase. Each shadow clone focused on one direction, freeing Shuichi to concentrate his efforts on researching Hashirama cells and Asuka's cells.
Time passed, and March of Konoha's 46th year quickly ended.
The negotiations between Konoha, Sunagakure, and Iwagakure continued. Unwilling to concede, Iwagakure kept engaging in small skirmishes in the Lands of Rain and Birds.
With the arrival of April, the intensity of the war began to increase once more, and figures like Kakashi and Guy returned to the battlefield.
Meanwhile, Shuichi, keeping a close eye on the Land of Rain, received more and more intelligence on the Akatsuki from Sarutobi Shinnosuke. Yahiko and his companions were becoming increasingly active, their reputation spreading widely across the Land of Rain.
Yet Shuichi knew a dramatic shift was looming for the Akatsuki.
One day, while researching at Orochimaru's experimental base, Shuichi was suddenly notified by Orochimaru that Danzo wanted to meet him.
"I understand. Let him wait a bit," Shuichi replied nonchalantly.
Orochimaru didn't mind and asked with a smile, "How is your research on Hashirama's cells going? It looks like you really have no intention of implanting them."
Without looking up, Shuichi replied, "To gain the power of Hashirama's cells, implantation isn't necessarily required."
Orochimaru's eyes narrowed as he felt a sudden surge of vitality from Shuichi's cells—a vitality strikingly similar to Hashirama's. Though it couldn't quite match Hashirama's cells, it was the most potent life force he'd seen besides them, surpassing even the Eight-Tails.
"As expected of Shuichi-kun…" Orochimaru's gaze was intense. "You achieved this purely through Yang Release?"
Shuichi nodded. "Yes."
"Of course, it requires a vast chakra reserve, which depends on a strong physical foundation."
"Indeed, the nature transformation originates in the mind and is manifested physically."
Orochimaru couldn't help but praise, "Shuichi-kun, your understanding of chakra and jutsu's essence is astonishing!"
Even knowing the secret, Orochimaru's chakra reserves wouldn't suffice. Among the Sannin, Jiraiya had the largest chakra reserve, followed by Tsunade, with Orochimaru at the bottom.
Shuichi's words, though, proved invaluable to him.
Thus, even though Shuichi hadn't asked, Orochimaru proactively added, "Shuichi-kun, Danzo has fused Hashirama cells with a Sharingan bearing three tomoe. His strength is formidable."
Shuichi smiled, "Thanks for the warning. I'm quite looking forward to it."
…
"You're late!"
Danzo frowned at the belated arrival of Shuichi.
Shuichi chuckled, "I'm extremely busy. Coming and going as I please—what, do you think I'm Hokage?"
Danzo's face darkened.
However, he knew that Shuichi was no longer the child he once was; his strength could now rival the tailed beasts. Shuichi's extensive connections within Konoha also made him untouchable.
Suppressing his anger, Danzo took on a cooperative tone and asked, "What's the progress on your research with the tailed beasts?"
"Rest assured; I'll provide you with equivalent intelligence in exchange."
Shuichi nodded with satisfaction.
"This is what a partnership should look like!"
"The experiments in the Daimyo's territory were all unsuccessful. The theory remains intact, but finding suitable individuals is extremely rare."
Shuichi shared his information. "However, Kakashi's experiments show promising results."
"As it stands now, he is the most likely candidate to wield the power of a tailed beast."
Danzo's gaze sharpened. "Kakashi, huh…"
Shuichi looked at him. "Why, are you interested in Kakashi?"
"Seems all your Root experiments failed."
"Clearly, you haven't grasped the concept of spiritual will yet!"
"A killing machine without emotions doesn't equate to strong willpower."
"On the contrary, they're even more fragile than ordinary people!"
Danzo's expression soured. "So you knew this all along?"
Shuichi nodded honestly. "Of course. The theory originated from me."
In front of an old man, Shuichi saw no need for deception.
Danzo, however, could only seethe internally, wishing he could use his Sharingan to obliterate the smug young man before him!
"Alright, I've given my information," Shuichi said with a smile. "Now it's your turn."
"All research data on the Sharingan and Hashirama cells. I know you handed Hokage a diluted version."
Cursing Orochimaru in his heart, Danzo outwardly remained composed and nodded. "No problem."
"And if you need a Sharingan, I can also provide one."
Shuichi, however, remained unmoved. "That won't be necessary."
"I prefer to obtain power on my own!"
He wasn't foolish enough to let Danzo hold something over him.
When he transplanted a Sharingan into Rin Nohara, it had been approved by the Third Hokage, so the responsibility ultimately rested with the Third. Additionally, with Obito Uchiha's involvement, even the Uchiha clan's reaction was tempered.
However, if Shuichi himself transplanted a Sharingan, especially a three-tomoe Sharingan, it might harm his friendship with Shisui.
Besides, a mere three-tomoe Sharingan was hardly of use beyond Izanagi or Izanami.
If he truly wanted a Sharingan, he'd bring the Divine Tree and unlock the Rinnegan directly, gaining both the Rinnegan and Sharingan powers.
After gathering the data he needed, Shuichi turned and headed to the Hokage Tower.
In the Hokage's office…
Handing the data to Hiruzen Sarutobi, Shuichi said, "It appears that Root's experiments have mostly failed, as expected."
"Danzo, however, has already gained the power of Hashirama's cells and the Sharingan. If the Sharingan becomes public knowledge, it could deepen the rift between the Uchiha and the village."
Hiruzen was used to Shuichi's relentless scrutiny of Danzo.
But at the moment, he couldn't act against Danzo; he needed him to handle certain matters.
Shuichi understood this well.
A chamber pot may smell foul, but it's quite useful when needed—keeps one's hands clean.
Unfortunately, Hiruzen's hold over Danzo was weakening.
"I will personally discuss this with Fugaku," Hiruzen decided with a sigh, feeling the frustration of having to clean up Danzo's mess.
Shuichi wasn't surprised by Hiruzen's decision, so he simply added, "Lord Hokage, I require the First Hokage's Wood Release techniques."
Hiruzen's eyes sharpened. "Shuichi, are you planning to transplant Hashirama's cells?"
Shuichi shook his head. "No, I intend to create Wood Release myself by combining Earth and Water Release."
"Wood Release is merely one of many Kekkei Genkai. The true strength behind the First Hokage's Wood Release lay in his immense Yang Release power."
Hiruzen nodded in understanding. "I see."
"Then Shinnosuke will escort you to the Scroll of Seals to copy the Wood Release techniques."
…
Upon leaving the Hokage Tower, Shūichi now held a scroll containing all the Mokuton techniques.
Studying Hashirama's cells alongside Mokuton techniques, and with the boosts of the [Prodigy] Tag, he didn't need to implant Hashirama's cells to gain Mokuton abilities. Whether his Mokuton could match the First Hokage's depended on his Yang Release mastery.
Although Shūichi's Yang Release was not as strong as the First's, in Sage Mode or Curse Mark state, he could rival the First's base form. Additionally, his research on Hashirama's cells continued, and with the [Prodigy] Tag's boost, acquiring knowledge from his studies to catch up with the First was merely a matter of time.
Back home, Shūichi created shadow clones to delve into the Mokuton techniques, then summoned a flock of crows and cast the Crow Clone Technique, sending them towards the Land of Rain.
With Akatsuki becoming increasingly active and Danzo likely ready to make his own moves, Shūichi sensed that a new act in this drama was about to unfold.
He had no desire or means to stop it. In fact, the day's events spurred him to revise his previous plans—Danzo was just too dangerous to let live.
After sending off the crows, Shūichi headed to visit his mentor, Minato Namikaze.
"Oh, Shūichi?" Kushina Uzumaki greeted him at the door. "Kakashi says you've been quite busy lately!"
As Kushina led Shūichi to the study, Minato looked up from studying the [Soul Sealing Seal] Shūichi had given him and smiled, "Shūichi, perfect timing! I could use your insight on something."
Shūichi stepped forward, smiling, "If you first learn the Spirit Transformation and Soul Binding techniques, it'll make it easier."
The Soul Sealing Seal, which Shūichi had developed to help Asuka better utilize her Adamantine Chains, allowed for soul-binding capabilities as a separate technique.
"Too much trouble; better to succeed all at once," interjected Kushina casually.
Shūichi didn't hold back, "That's just you being lazy, Kushina-san!"
Kushina laughed, "Hey, it's all about working smarter, not harder."
After answering Minato's question, Shūichi asked, "So, how's your progress with the Rasengan, or even the Wind Release: Rasenshuriken?"
Minato and Kushina exchanged a glance, their expressions growing serious.
"I'm comfortable with the Rasengan," Kushina said. "But I can't manage to throw the Rasenshuriken."
Minato nodded. "I've run into the same issue. But with my Flying Thunder God Technique, throwing isn't really necessary."
"That should be fine then," Shūichi replied. "The main concern is resisting the malice of the Nine-Tails—its negative energy is overpowering, but…"
Looking at Minato and Kushina, Shūichi grinned. "I trust you both to handle it!"
Kushina laughed, clenching her fist with determination. "Of course! I'm fully confident!"
"Now then…" Shūichi asked, "Sensei, have you decided where the other half of the Nine-Tails will be sealed?"
Minato answered, "We'll seal it in you."
"I've discussed it with the Third Hokage. Though we could give half to the Sand or Stone villages, we need to be prepared in case they discover it. Keeping half in you prepares us for anything unexpected."
This arrangement suited Shūichi perfectly, and he nodded. "Then it's settled. Starting today, Kushina-san can start sparring with the Nine-Tails' chakra."
Seeing them look a little tense, Shūichi laughed. "We'll take it step by step—first split the Nine-Tails, then adapt to its chakra, and finally, show it who's boss!"
Kushina's eyes lit up, her fist clenched in excitement. "Oh, I've been waiting to teach that beast a lesson!"
The Nine-Tails had been far from tame in her, frequently stirring trouble. Without the strength of her predecessor, Mito Uzumaki, she couldn't fully suppress it. It would be her pleasure to put it in its place—and avenge Minato for last time, no less!

With the decision made, Shūichi and Minato set out to prepare. They chose a secluded forested area in the mountains of Konoha, building a small cabin and erecting a barrier for extra security.
Although they were confident in subduing the Nine-Tails, they took every precaution. Three days later, preparations were complete.
Outside the barrier, Sarutobi Shinnosuke led a team alongside Shūichi's shadow clone, holding watch.
Inside the cabin, Shūichi and Kushina sat facing each other, while Minato held her hand, channeling chakra to form a mental connection.
With a soft, metallic clink, fiery chains extended from Shūichi's abdomen, snaking forward. He called out, "Kushina-san, release the seal!"
"Understood!" Kushina nodded firmly, lowering her gaze.
In the next instant, the outermost Eight Trigrams Seal on her abdomen was lifted.
With a loud whir, Shūichi's flaming chains shot forward, burrowing into Kushina's abdomen and pushing through the seal's gateway.
At last, Shūichi laid eyes on the Nine-Tails.
Hmm? It seemed a bit… subdued.
It was nothing like the unruly fox locked inside Naruto in the future; this one was pinned midair.
Beyond the chains, stakes pierced its body and tails, rendering it immobile—evidence of Konoha's or possibly even Hashirama's sealing techniques.
"Looks like nobody could handle this going forward…" Shūichi mused thoughtfully.
At that moment, Kushina and Minato's forms appeared beside him.
Suspended in midair, the Nine-Tails glared down at them, growling, "Cursed humans…"
Roar!
With a thunderous howl, it whipped up a furious gale, causing their hair and clothing to whip wildly.
Shielding her face, Kushina cast Shūichi a worried glance. "Shūichi, are you sure? This thing's power is overwhelming!"
Shūichi nodded solemnly; indeed, the Nine-Tails' strength was unmatched. In terms of sheer power, especially chakra volume, even Shukaku or the Four and Eight-Tails paled in comparison.
Moreover, Shūichi could sense the distinct potency of the Nine-Tails' chakra.
It wasn't just the quantity; it was the quality—chakra of unparalleled essence.
"No wonder it's the tailed beast closest to the Ten-Tails…" Shūichi thought in awe, before saying with resolve, "Since we're here, we have to give it a try."
"Kushina-san, unleash the seal!"
"Sensei, I'll be relying on you in a moment."
Minato nodded solemnly.
Kushina raised her hand decisively. "Let's begin!"
