Hearing Chang Yuan's words, Vill-V quickly snapped back to reality.
Without delay, she used the tools she had prepared earlier to extract the core from the Herrscher of the Void.
Holding the core in her hands, Vill-V's eyes sparkled with excitement.
"Vill-V, this time, don't make a locomotive. Make something useful, like a weapon. If we really have no other options later, you can go back to making locomotives."
"Huh? How did you know I was planning to make a locomotive? Wait, no, has your ability to predict the future gotten stronger?"
Seeing Chang Yuan immediately guess her intentions, Vill-V was somewhat surprised.
After all, she had already known about Chang Yuan's ability to foresee the future.
So she wasn't too shocked by it.
"Good grief, so you really were going to make a locomotive, huh? Think about the Fourth Herrscher, Vill-V!
Her authority is over ideal fluids. Without the right means, our current human technology can't even scratch her!
So, take this Herrscher core and make a spatial weapon for me! Don't make a locomotive! Do you really think you can run over the Fourth Herrscher with a train?"
Hearing this, Chang Yuan's mouth twitched uncontrollably.
Oh, Vill-V, my dear 'Big V Teacher,' you were really going to make your locomotive, weren't you?
Do you know that in the original story, it was because you made that locomotive that Dr. Mei banned you from making Divine Keys?
"Alright, alright, I get it. My locomotive was already finished, and I just needed to install the core to make it work."
Hearing Chang Yuan's words, Vill-V pouted but eventually agreed.
After all, many of her recent inspirations had come from Chang Yuan.
So, in a way, he was half the creator of the Divine Keys.
Seeing that Vill-V had abandoned her whimsical idea, Chang Yuan breathed a sigh of relief.
"By the way, for the weapon, use a bow as the prototype. I believe that if Elysia had such a bow, she would be unmatched against future Herrschers, except for a few particularly troublesome ones."
Spatial abilities—this was the most terrifying offensive power, impossible to defend against.
Apart from the Ninth Herrscher's gravity, the Eleventh Herrscher of Binding, and the Twelfth Herrscher of Corruption, only the Herrscher of Death could withstand a few arrows.
The rest of the Herrschers would die the moment they were hit.
If Elysia had been given a bow-shaped Divine Key made from the Herrscher of the Void's core in the original story, human losses might have been reduced by at least half.
Unfortunately, due to humanity's lack of understanding of the Honkai in the original story, they chose to create a locomotive-shaped Divine Key to observe parallel worlds and uncover the true nature of the Honkai.
But now, since Chang Yuan already knew the truth, there was no need for a locomotive-shaped Divine Key.
"That works too. Give me about a month, and I should be able to make it. It'll be awesome, I promise."
With her preliminary experience, Vill-V was confident she could complete it within a month.
Unless it was a large-scale Divine Key, a small weapon like this would only take a month.
"So, what exactly did you leave for Vill-V when we left last time?"
Elysia had also picked up on many key details from the conversation.
But all these key details came from Chang Yuan.
Elysia had reason to suspect that Chang Yuan had left something significant with Vill-V when they parted ways.
Otherwise, why would Vill-V show up with anti-Honkai serum and Divine Keys right after meeting them?
"Hehe, hasn't Chang Yuan told you yet? Then I can't spill the secret for him."
Hearing this, Vill-V decided to keep Chang Yuan's secret for him, at least until he chose to reveal it himself.
"Yuan, how many more secrets are you hiding from me?"
"I don't know, but I think there are quite a few."
Looking at Elysia's expression, Chang Yuan smiled warmly.
"Alright, time is running out. Vill-V, you should leave now. I'll call you when I need you next time."
"Got it. I'll be waiting. See you later."
With that, Vill-V quickly disappeared using her small flight pack.
Watching Vill-V's retreating figure, the area was soon surrounded by Fire Moth personnel.
"Who are you? Did you kill that monster?"
Looking at the Herrscher of the Void, whose appearance matched the intelligence reports and who had died from an arrow piercing her brain, the Fire Moth support team members were astonished.
This monster had slaughtered countless of their comrades, yet it had been taken down by two unknown individuals.
"Us? We just joined Fire Moth, but our information hasn't been entered into the database yet. We were sent here to deal with the monster."
"I see. Having strong individuals like you join Fire Moth is a great boon for humanity."
Having experienced the feeling of life slipping away beside them, they knew just how terrifying the monsters they faced were.
So, they welcomed the addition of powerful individuals to Fire Moth.
"Alright, since you successfully took down the monster, the credit should go to you two.
But since your information hasn't been entered yet, come with me to get registered."
"Sure~?."
Seeing this, Elysia nodded with a smile.
She wasn't exactly lying—she was just using a bit of linguistic artistry. After all, wanting to join now counted as joining, right?
As for the Herrscher's body, other support personnel would handle that.
Seeing how easily they had slipped into Fire Moth, Chang Yuan couldn't help but facepalm.
After completing the registration, Elysia and Chang Yuan went to see Mobius again.
"Dr. Mobius, I'm sorry for deceiving you earlier. We weren't sent by the council to retrieve your badge. We just needed an identity to enter the perimeter and deal with the monster. Otherwise, the people outside wouldn't have let us in."
Handing Mobius's badge back to her, Elysia apologized sincerely.
Taking the badge, Mobius glanced at Elysia.
"I don't care. You survived, and that's your luck. But don't get too close to me. I hate people getting near me."
With that, Mobius went to prepare her sterilized lab coat.
Soon, she would personally dissect the second monster.
She hoped to gain some useful information or materials from it.
