To create Honkai Impact 3rd in a world where Kallen exists.

I never imagined that something buried by history could be brought up again and slapped in the face.

Shouldn't that have been forgotten by now?

And... even Senior Sister Klein couldn't persuade her?

"Tell me honestly, did you do it on purpose that time?"

Danzhu, hands on his hips, arrogantly criticized the other party.

That's right... this is the leverage.

Unfortunately, it's a weakness that everyone in the world knows about.

"...I just mentioned what the Doctor was doing unintentionally, it doesn't really concern me. But...is there really anyone who can change the Doctor's decision?"

She sighed.

"If even Senior Sister Klein can't do it..."

"I think Alicia can definitely do it, or... when Qianjie stood on the side that made the decision for Mebius, she would definitely have taken a detour!"

Danzhu said confidently, having thoroughly read about Ying Jie's deeds, she became increasingly engrossed in them.

It's worth noting that even Luo Mo's offer to serve as a consultant for the Yingjie series of comics and films was accepted.

In Cang Xuan's view, this was a suicidal act that would inevitably lead to his elimination sooner or later.

If you get involved with that Luo Mo.

"..." Cang Xuan glanced at the other person subtly, and had to admit that what she said was indeed reasonable.

But that's not the kind of change she wanted.

It's the kind of change that allows for normal communication... although it probably won't happen anymore.

...

Now, across 50,000 years, the same choice is once again placed before Klein.

However... in her view, the person she was facing was no longer the PhD she once knew.

"...What, haven't you made up your mind yet?"

Before her stood the memory that should have been corrupted and ceased to exist.

It is speaking to itself in a mocking tone.

She made the right judgment once again—connecting the paradise of the past with reality under the watchful eye of the Herrscher of Corruption was a near-impossible task…

Only Paradise itself can make it possible... or the person who calls himself Paradise itself.

Aponia's departure brought Mebius's message to Klein.

This is something only her unique circumstances could enable her to do.

"So, you had already solved the problem that no virus could control back then, Bo... Mebius?"

Klein looked at the projected phantom of the Doctor in front of her and lowered her head slightly as she spoke.

"Through... a replica of the former Twelfth Herrscher."

"A counterfeit? A mere Herrscher of Erosion..."

"What I create will only be something that surpasses her."

Mebius's projection narrowed its eyes and said arrogantly.

"However, there are currently no anomalies in the data at the Paradise of the Dead..."

Klein was still hesitant.

Should she trust him?

"Enough, Klein. Since when have you become so opinionated?"

Mebius snapped, she had to act quickly, before the Herrscher of Corruption could react. "I don't have time to answer your questions, you just need to do as I say."

"If it were so easy for outsiders to detect the presence of a Herrscher... then meeting you wouldn't be as complicated as it is now."

"..."

"I can tentatively assume that the Herald of Corruption of this era exists in Paradise."

"But according to what you just said... your current state of corruption is intentional."

"In this way, you implanted that replica into the Herrscher of Corruption's data."

"Otherwise what? Is there a simpler method that would not arouse suspicion?"

"And stop using that stupid argument. Or... in your eyes, am I really just a counterfeit?"

"As I said before, what I implanted at that time was myself—the first experimental subject of the artificial Twelfth Herrscher."

"It was also...the first success story."

"You think she corrupted me? Actually... quite the opposite."

"But now it seems that you don't have the ability to self-replicate, otherwise... coming here would have been pointless."

Klein looked at the other person and said calmly.

"It's all because of Vilvi's doing. If she hadn't used the backdoor to delete those viruses under my control, we wouldn't be in such a mess now."

Mebius spoke with a hint of sarcasm, realizing that Virvie's useless actions back then had only bound him, forcing him to rely on external people to replicate his work.

"So, that's why you need me to complete the final step?"

"Using the permissions of the hardware facilities, can those counterfeit viruses be propagated in Paradise?"

"That's right, using the former Twelfth Herrscher to fight against the current Herrscher of Corruption, don't you think... the outcome is very exciting?"

"This is...an unprecedented attempt."

"..." Klein remained silent.

They simply gazed at each other silently.

"What are you still hesitating about?"

"Is this yet another plan you've devised to bring someone back to life?"

"If you succeed, you will not only return to reality, but you will even possess powers similar to those of the Herrscher of Corruption..."

Upon hearing this, Möbius chuckled twice, showing not a trace of anger.

She had seen far too much betrayal and distrust.

“It’s alright, you don’t need to believe me, Klein.”

"You can choose to leave, tell others what happened here, or personally dismantle Paradise's system and end it all."

"You just need to admit that we don't have many options right now... and this is one of them."

"As for my immortality, it's just some... insignificant side effects."

Klein knew she was right.

In the data space, there is only one Herrscher of Corruption who can rival the Herrscher of Corruption.

Finally, Klein's hands moved on the control panel as Mebius had instructed.

That's how it is.

Mebius encouraged her from the sidelines, and in the midst of the confrontation, Klein chose to believe what she said.

"Please don't disturb me, Mebius."

Klein looked down at the buttons on the control panel and quickly and skillfully performed the operations.

"You want me not to bother you? I never thought this day would come... What's this, a role reversal?"

Möbius said with great interest, unhurriedly, "Don't worry, we still have plenty of time..."

"Klein?!"

The phantom looked at Klein, who had paused for a moment, and frowned slightly.

Just now... it seems something else did happen.

Has it been noticed?

"Um……?"

"It's the Herrscher of Corruption. Has she already discovered us?"

The small, green-haired figure paused for a moment, Klein's gaze darkened, but his hands moved faster involuntarily, as the other person's words carried even more weight.

Therefore, we can no longer give up.

"Klein, get off that machine."

"The phantom of Mebius said anxiously,"

But Klein did not react.

"...Since she is trying to stop us, then this is indeed an effective solution."

"Please don't disturb me... Doctor."

For the first time, the person who never went against her advice and always supported her expressed his opposition.

In other cases, even those only slightly better than this... Mebius might be happy to see them.

But not now.

It cannot be at this moment when the other person is about to die.

Moreover… that form of address also bothered her somewhat, even though she could easily find similar instances of it in her past by casually flipping through her long memory.

—In the laboratory, it was often just the two of them tackling difficult problems.

But she had thought... that her previous attempt to seize the Herrscher's body meant that the Herrscher was no longer her only confidant.

"……Why?"

"Fine... Stop right now, Klein. At least for now... I still have a way to save you."

“I don’t need you to copy the virus anymore. Get out of here—destroy all of Paradise’s hardware facilities, and then get far, far away.”
