Sorry, you scumbag woman, you can do whatever you want.

"...Having already made the decision to kill Theresa, is it necessary for you to care about these things?" Mebius chuckled. In the previous life's story, she already understood Kallen's choice, which was to die with Theresa.

Kallen made this difficult choice after realizing that Theresa's vampiric urges were uncontrollable and would constantly harm people.

Of course, she could also choose to take Theresa to the Fate Gate and ask Otto for help, but that would only lead to one outcome.

Theresa, who was already a caged canary, will be completely locked up by Otto, cutting off all possibility of escape.

In fact, to ensure Theresa could not escape, they chose to strip her of her consciousness or the limbs she used for action.

And in that case... Theresa would suffer more than if she were dead.

Therefore, Kallen chose to die with Theresa, ending their twisted and distorted lives.

“Please tell me, what do you want to do with Theresa?” Kallen’s tone softened.

Indeed, she had considered killing Theresa, but due to the change in her current situation, her stance has also changed.

More concern is directed at Theresa May and the innocent civilians.

Even if you know, you can't stop it; it will only cause you more pain. Are you sure you still want to know?

Mebius smiled and asked, looking into Karen's determined eyes, confirming her thoughts.

Therefore, she selectively revealed only parts of the truth.

A few minutes later.

"So, you're using Theresa's power to save lives?" Kallen looked troubled. "But the price is that Theresa's bacterial Honkai Beasts will uncontrollably spread among the human population until they infect all of humanity, right?"

“That’s right, exactly.” Nodding slightly, Mebius smiled. “Great Saintess, do you want to stop the spread of the bacterial Honkai Beasts, as long as you kill or control the infected people?”

She whispered in a seductive tone.

"Then humanity... is still the humanity you think it is."

Can't do it.

Kallen didn't answer, but she already knew the answer in her heart, even though she felt it wasn't good to let the bacteria-spreading Honkai Beasts go unchecked.

However, she could not stop people from living, nor could she stop them from helping their relatives and friends to live.

Could it be that she's being told by those who have her terminal illness that spreading bacteria and Honkai Beasts will cause humans to cease to be human?

So, should people with terminal illnesses just wait to die?

This... was clearly impossible; even her simple morals and sense of justice could not prevent people from being saved.

“That’s why I said knowing the truth would only cause you pain.” Mebius sighed helplessly, picked up the teapot on the table and poured Karen a cup of tea. “However, you can just try to comfort yourself by changing your perspective.”

She gestured for Karen to drink some tea, explaining to her with a smile.

"Civilization can continue to advance and accumulate strength, but people themselves are easily left behind by the rapidly advancing civilization."

"..." Karen held her teacup, listening intently. She felt that what Möbius was about to say would prevent her from making a painful choice.

"As people get older, the cost of accepting and learning about the creations of civilization as it progresses increases. The same is true for young people. As the human knowledge system continues to improve, the cost and effort required for learning also increase."

Mebius asked Karen.

"Karen, do you think that humans today are capable of learning all the subjects of knowledge?"

"I don't know." Karen shook her head; she wasn't very familiar with the knowledge system of human civilization.

If it's about fighting, then she can talk about it.

“The answer is, with the exception of a small number of people,” Möbius replied with a smile. “No one can learn the entire human knowledge system. During the time when they are most energetic and creative, they have to spend their time on the complex knowledge system of school, and this is only when it is limited to specific subjects.”

She gave a summary to Karen.

"Human civilization has advanced too fast, leaving humanity behind and making those who come after struggle to catch up."

"So, you want... to help humanity catch up with the pace of civilization?" Kallen understood Mebius's line of thinking, "...through the modification of humanity by bacterial Honkai Beasts?"

“After being modified by the bacterial Honkai Beasts, human lifespan and energy will no longer be an issue. Even if we have to spend decades or hundreds of years learning again, it is still possible.” Mebius pointed to the brain. “Moreover, during this period, people’s brains will also maintain corresponding vitality and creativity.”

"By extending human youth, people are able to keep up with the times."

"That is, to enable humanity, which lags behind civilization, to catch up with civilization."

"..." Karen fell silent. She felt that what Möbius said made a lot of sense, and she couldn't find any words to refute it.

However, something just feels off.

“Karen, if you still don’t feel it directly enough,” Möbius continued with a smile, “then please imagine yourself in a nursing home, teaching the elderly how to use a computer, or learning and absorbing knowledge of modern civilization.”

"It feels like it's going to be a lot of trouble." Karen bluntly expressed her feelings; both of these things were very difficult for her.

"...Have you felt the difficulty of catching up with civilization?" Möbius concluded. "Humanity needs to evolve, to evolve thoroughly and completely, in order to better adapt to and create the civilization."

"Is this really... alright?" Karen asked one last question. Helping humanity adapt and catch up with civilization is undoubtedly a good thing.

But is there really no risk involved?

“This is the problem we need to solve,” Möbius said with a smile to Karen. “To help humanity catch up with civilization, cooperate with my research.”

“If that’s the case, then yes!” Karen nodded, resolving to accept the decision.

Yes, the deception was successful.

-------------Chapter Dividing Line---------------

They were unwilling to revive Kallen.

After going through a complicated and troublesome inspection.

In the laboratory.

“…This is a bit troublesome.” Möbius sat in her office chair, wearing a researcher’s white lab coat, her long legs wrapped in black stockings crossed, staring at the final report in her hand, a troubled expression on her delicate face.

Meanwhile, Karen sat on a bench nearby, watching Möbius's somewhat troubled expression, and gave him a serene smile.

"Excuse me, is it true that my memories cannot be recovered?"

She had expected this outcome. If her memories were so easy to recover, she would have been cured by Otto long ago, and there would be no need to wait for Mebius to help with the treatment.

However, there's no need to be too disappointed. Her cooperation with Mebius was mainly to help him make the bacterial Honkai Beasts controllable.

It's simply to make it easier to treat more ordinary people with terminal illnesses.

“If it’s just about restoring your memories, I still have a way.” Mebius shook his head, and after Karen showed a surprised and delighted expression, he coldly stated the truth, “But that would be tantamount to killing you.”

"..." Kallen's surprised expression froze. She lowered her head slightly, obscuring her expression, then tilted her head back and smiled, "How could that be? It's just regaining memories, not..."

“Of course you are, do you think you are?” Möbius replied coldly, “a saint from five hundred years ago?”

She continued looking down at the documents.

“Your consciousness was born from the corpse of Saint Karen. If Saint Karen’s consciousness is revived, you… will cease to exist.”

"No, to be more precise, you died and a person who thought he was Kallen was born. It's just that this new consciousness is more like the Kallen in Otto's memory, nothing more."

"...Can you tell me how you plan to restore her memories?" Kallen asked Mebius. She still harbored a deep attachment to the saint Kallen from five hundred years ago; anyone possessing the same body, power... and some of her memories... would be a different story.

They must all have some special obsession with it.

“…” Mebius did not answer, meeting Karen’s calm and firm gaze, as if she had already made up her mind.

"In this generation of humans, all bodies have sacred marks, the only difference being the degree of awakening. And the sacred marks... happen to have a function that is not widely known: recording all the information of the body's owner, including memories."

She placed the report in her hand on the table.

"In other words, as long as you extract that memory and then delete all your memories, it's equivalent to resurrecting Kallen in a certain sense."

In this era, few people have a deeper understanding of Stigmata than she does, but she is an exception.

Not long ago, she acquired the knowledge of this incarnation of Mebius. Although she had not fully digested it, her understanding of the Stigmata was undoubtedly profound.

Therefore, it is possible to artificially awaken sacred marks and extract memories, as long as she feels there is a need for this.

"..." Karen raised her hand and touched her forehead. She was caught in an extremely difficult choice. It seemed that every time she met Mebius, she would be faced with an extremely difficult choice. This time... it was even more about her own life and death.

How to choose?

"Let me make it clear beforehand, I have no intention of extracting the memories of the Stigmata." Mebius glanced at Kallen, and amidst her puzzled yet somewhat relieved expression, he casually explained, "I have no intention of doing something so meaningless, as it is of little significance to both me and Otto."

In fact, she never intended to resurrect Kallen from 500 years ago, nor could she possibly do so.

Moreover, the current Kallen... is Theresa's sister. If she kills the current Kallen, how will she face Theresa?

Therefore, she never intended to resurrect Kallen from five hundred years ago; it was merely to get Otto to cooperate with her actions.

Of course, Otto himself must have understood this, but humans are strange creatures, even when they know the truth and the answer.

Yet, they still choose to deceive themselves.

She was willing to give it a try simply because she was using the identity of a hero from a previous civilization, one of the most powerful researchers of that era.

Although Otto himself knew the answer in his heart.

Yet they still choose to deceive themselves.

"Why?" Karen asked Möbius, expressing her confusion. She also realized why Otto was so lenient with Möbius, who had done something that threatened all of humanity, yet he still did nothing.

That was purely because Mebius had the hope of resurrecting Karen from five hundred years ago.
