Today, Uchiha Shin had finally mastered everything he needed to and was now heading to Mount Myoboku to complete his final Sage Mode.
Afterward, he planned to use the unique ability of his left Mangekyō Sharingan, [Reflection], to merge and construct an entirely new Sage Mode.
Given that he could already use both the Sage Modes of Ryūchi Cave and the Shikkotsu Forest simultaneously, Uchiha Shin was confident in his ability to create something unparalleled.
"Then, this is where we part ways for now, White Snake Sage. I am grateful for your guidance during my time here.
And to you three—Tenka, Ichikishima, and Tsujinji—thank you for taking care of me during my stay.
I've been here long enough. It's time for me to move on."
Uchiha Shin expressed his gratitude to the three snake princesses standing before him. For the past two months, they had been tending to his daily needs in Ryūchi Cave.
Had it not been for them, he might have ended up sleeping out in the open, much like how things had been during his time in the Shikkotsu Forest.
The three snake princesses wore expressions of reluctance upon hearing that he was leaving.
"You're going? Shin-sama, I hope you visit often. I'll be waiting for you always," Tenka said with a sultry smile.
"Why not stay a little longer and have some fun? It's rare to meet a human who's interested in me. If you leave, I'll be so bored again," Ichikishima pouted, wrapping her tail around his wrist playfully.
"Ichikishima, don't make things difficult for Shin-sama. He has his own path to follow. However... Tsujinji would also love for you to visit often," Tsujinjihime said, her words smooth yet carrying an undeniable undertone of expectation.
Uchiha Shin found himself momentarily speechless, uncertain how to respond to the attention of the three beauties.
At that moment, the White Snake Sage chuckled and interjected, "If you three feel so strongly, then why don't I officiate a summoning contract between you and Uchiha Shin?
That way, you'll always be connected, and he can summon you whenever he wishes. What do you think?"
The White Snake Sage's slitted eyes turned toward Uchiha Shin, gauging his reaction.
Hearing this, Uchiha Shin naturally had no reason to refuse. There was no limit to the number of summoned creatures a shinobi could contract, and this would only be beneficial to him.
Tenka, Ichikishima, and Tsujinji exchanged glances and smiled in satisfaction.
Under the White Snake Sage's supervision, the contract was swiftly established.
Without further delay, Uchiha Shin activated the Reverse Summoning Technique and vanished, heading straight for Mount Myoboku.
Once he was gone, the White Snake Sage turned to the three princesses with a knowing smirk.
"I know what you three are thinking. If you truly desire him, then go ahead and capture his heart. I won't stop you."
The sage had noticed how the trio had grown attached to Uchiha Shin during his stay.
Of course, this wasn't entirely a coincidence—she had subtly orchestrated it. After all, the best way to ensure loyalty was through deep personal bonds.
If the three princesses closest to her were to develop a relationship with Uchiha Shin, then he would be bound to Ryūchi Cave forever.
"The old toad and the slug queen can teach him Sage Mode at best, but I? Heh, I can send my most trusted people straight into his bed. This is my advantage!"
The White Snake Sage tossed her flowing orange hair back, her expression one of smug satisfaction.

It didn't take long for Uchiha Shin to reach Mount Myoboku.
In just a single day, he had completely mastered the Myoboku Sage Mode.
The elders of the mountain, including Gamafukasaku and Shima, nearly had their eyes pop out of their sockets in disbelief.
Upon learning that Uchiha Shin had already mastered the Sage Modes of Ryūchi Cave and Shikkotsu Forest, they were slightly less shocked, but even so, his speed was simply incomprehensible.
It had taken him less than a day to go from absorbing natural energy to perfecting the Myoboku Sage Mode!
The toad markings on his face were the undeniable proof.
While Gamafukasaku was still questioning the very foundations of the world, Uchiha Shin took the opportunity to slip away.
Deep within Mount Myoboku, the Great Toad Sage, who had long been in slumber, slowly opened his ancient eyes.
"A descendant of the Uchiha clan... Since his arrival, my dreams have been thrown into chaos.
The path of the future... it is no longer what I once foresaw.
Now, everything depends on fate."
The Great Toad Sage murmured, his voice filled with deep uncertainty.
His prophetic dreams had been altered by Uchiha Shin's existence.
He no longer knew whether this change was for the better or worse, and at this point, he lacked the power to intervene.
All he could do was watch as events unfolded.

Upon returning to Konoha, Uchiha Shin decided to visit Tsunade.
However, when he arrived in her quarters, she was nowhere to be found.
Running a finger over the dust gathered on the wooden desk, he raised an eyebrow. "No one's been here for about two months... Did she head to the battlefield?"
Before he could contemplate further, a soft "pop" sounded beside him, and a small slug appeared on the table.
"Master Uchiha Shin, Lady Tsunade has gone to the Shikkotsu Forest to train. She won't be back for some time."
"..."
"Huh?"
Uchiha Shin was momentarily stunned.
Hadn't it been said that Tsunade lacked the aptitude for Sage Mode?
How was she suddenly capable of learning it now?
Noticing his confusion, the small slug explained further:
"A substantial amount of natural energy had accumulated in Lady Tsunade's body. Over time, it began altering her physique, awakening her Senju lineage to its full potential.
As a result, she became qualified to practice Sage Mode.
She is now progressing rapidly, adjusting to her new abilities within the Shikkotsu Forest."
As the slug finished its explanation, Uchiha Shin turned his head away awkwardly.
He had a sneaking suspicion as to why so much natural energy had gathered within Tsunade's body.
After all, he had personally pumped her full of it...
He hadn't expected his 'enhancement sessions' to have such a side effect!
This... needed further testing.
He had to see if the same effect applied to Mikoto, Kanako, Kushina, and the others.
Suppressing the smirk creeping onto his face, Uchiha Shin watched as the little slug vanished, its task complete.
Shaking off his thoughts, he decided it was time to share his latest accomplishments with Mikoto and the others.
After all, while he had informed them beforehand that he would be away for a while, his two-month absence had still left them worried.
Having spent the day reassuring each of his beloveds, Uchiha Shin shifted his focus back to himself.
"With my mastery over [Yin Release], my ocular energy replenishes at an incredible rate.
I should have just enough power now to use [Soul Reflection] and construct my very own Sage Mode."
His words were quiet, yet filled with conviction as his eight-pointed star Mangekyō spun wildly in his left eye...
