"Um, I have to go report on my work situation to the Overseer."
These words came from the young man's mouth, making Miss Mei's expression stiffen slightly.
"What work?"
The girl, who had originally wanted to have a heart-to-heart talk with Li Zihan, felt the corner of her mouth twitch as she asked the question.
"I've told you about Chaldea before, right?"
The young man, feeling that having a heart-to-heart with Miss Mei right now would be very bad for him, narrowed his eyes and then spoke, bringing up the name of an organization.
He still hadn't maxed out Miss Mei's affection level. If he let her know he had plans for a harem, he would very likely be slapped across the face.
"Chaldeas."
The girl, vaguely remembering that it was a very powerful organization, nodded.
"A special agency that interferes with the past through spiritron transfer, making a certain degree of adjustments to the past without affecting the grand scheme of the world."
Li Zihan stuck his hands in his pockets. Relying on his outstanding memory, he very easily found Otto's contact information and sent a message.
(The most important device for spiritron transfer—the spiritron calculator—has been obtained. Let's discuss the benefits and crises of establishing Chaldea in detail next.)
He was unlikely to escape the interrogation process that was coming. Once Mei started asking a full set of questions for grilling a Sea King, he would have absolutely no way out.
He had to find an external force to interrupt that process.
"I've already found the most crucial item for establishing Chaldeas. The next step is to form Chaldea."
Miss Mei fell silent. This matter was indeed very important.
But when she remembered Li Zihan and Bronya casually walking into the kitchen, her expression turned hostile.
"Are you in that much of a hurry?"
"It is quite urgent."
Hearing these words, the young man's expression became slightly troubled.
But very quickly, his tone became cheerful again.
"However, if it's you who needs me for something, Mei, I can push the Overseer's matter back a bit."
Raiden Mei was stunned.
Li Zihan didn't choose to evade. His expression was calm as he waited for her question.
This development was somewhat out of her expectations.
"Is-is that okay?"
"I'm just a Vice-Commander of the Far East Branch in name only. There's no clear subordinate-superior relationship between me and Schicksal's Overseer, Otto."
Very relaxed words came from the young man's mouth.
"Everything has to be prioritized. Compared to Otto, your business is clearly a bit more important, isn't it?"
Is my business more important than an alliance with the Schicksal Overseer, who controls more than half of the hidden world?
This meaning easily entered the girl's mind.
A brilliant crimson blush rose on the girl's jade-like face, like a drunken red cloud.
"Won't the Schicksal Overseer give you trouble for slacking on the job?"
The one who panicked first was, contrary to expectations, the girl who was supposed to be the interrogator.
She didn't know Otto personally, but as the daughter of the high-ranking Anti-Entropy executive, Raiden Ryoma, she had learned some things from her father and her elders after coming into contact with the other side of the world.
He was the most terrifying man in this world.
Calm, cunning, cruel, and insane.
Simply because of a difference of opinion, he would possess the body of the strongest Valkyrie of the time and attack the First Herrscher who stood on humanity's side—Welt Joyce—and then drop a Honkai fission bomb on all of New York.
For his own unknown purposes, he would allow the Second Herrscher to create a natural disaster in Siberia, and even launch a surprise attack on Welt Yang, who had stepped forward to protect humanity, when he was exhausted, nearly killing him.
Without a doubt, Otto Apocalypse was the most dangerous man in this world.
Every contact with that dangerous man meant the reaper's scythe was grazing the neck of the one who contacted him.
And Li Zihan was one of the people in this world who contacted him most frequently.
"Zihan, you should go handle the Chaldeas matter sooner."
Raiden Mei bit her lip and struggled for a moment before speaking to the young man beside her.
Angering the Schicksal Overseer was a very dangerous thing. She couldn't let Li Zihan take such a risk because of her.
If she wanted to get clear answers about him, Bronya, Seele, and even Kiana, it would take a very long time.
But Li Zihan's time was tight right now. His willingness to come to this welcome-back banquet was probably him stealing a moment of leisure from his busy schedule. She shouldn't be asking questions at such a critical moment and wasting his time.
"That sort of thing is not urgent."
Looking at the slightly anxious expression of the girl beside him, the young man who should have been in a hurry to run away chuckled lightly, simply sat down, and waited for the questions.
"Zihan, be serious!!"
The tone of Miss Mei, who always spoke gently, suddenly rose by several octaves.
"I'm really not busy."
Before these words could even land, the phone in his pocket began to ring.
Someone was looking for him.
Li Zihan took out the phone from his pocket, and his face instantly became unpleasant.
"What's wrong?"
Miss Mei, who clearly sensed the change in Li Zihan's expression, suddenly felt her heart leap into her throat.
"It's nothing. Someone's looking for me."
The young man, whose phone's contact name was clearly written as "Otto," grinned.
Mei looked over. The contact on the phone was "Joker α"—a pen name Otto Apocalypse had once used.
"Mei, I'll come back and answer your questions later."
These words came from the young man's mouth.
He stood up, smiled at the girl, and then walked outside.
Raiden Mei watched the gradually departing figure, opened her mouth, wanting to remind him of something, but in the end, a thousand words all came to a halt.
"Come back soon."
Simple words, yet carrying a beautiful wish, came from the girl's mouth.
"Otto doesn't have many ways to deal with me."
The young man, who had already grasped Otto's fatal weakness and had an alliance with this world's strongest combat power—Kevin—smiled cheerfully.
With the girl's eyes following him, he left the dormitory and headed towards the distant library.
========Line Break========
"So, my friend, you have already brought the most important device for time travel to this world, as promised?"
In Vienna, somewhere in Schicksal's floating city, an extremely magnetic baritone voice rang out.
The source of the voice was a virtual library, transformed into the Vienna of five hundred years ago.
This world's biggest boss and top simp, Otto Apocalypse, bathed in the sunlight of five hundred years ago, was sitting at the table where he often had afternoon tea with Kallen as a child. He looked at the young man who had been gone for about twenty days and asked.
Just now, he had received a communication from the outlander with whom he had an alliance and had rushed over.
"Mhm. One of the most important instruments of Chaldea, the special service agency jointly established by various countries to prevent the extinction of humanity, the Spiritron Calculation Engine."
"Its specific function is to achieve intervention in the past by turning humans into spiritrons and deploying them to the observed era."
The magus from the Type-Moon world introduced the function of the Spiritron Calculation Engine: Trismegistus from Chaldea.
The Chaldea of the Type-Moon world had two main purposes: one was to observe the future, and the other was to change the past.
Observing the future used the Near-Future Observation Lens: Sheba.
The thing corresponding to changing the past was the Spiritron Transfer system.
Thanks to Reines's help, Li Zihan had very easily obtained the important item for the Spiritron Transfer system—the Spiritron Calculation Engine.
Interfering with the past to guide a new development, and then overwriting the old past?
What a terrifying power.
Otto, who knew very well what Li Zihan was talking about, felt his eyes flicker. His heart, which had been like stagnant water, was stirred by waves.
Kallen can finally be saved.
Experiment after experiment, failure after failure, followed by an endless cycle of experiment—failure—experiment again—failure again.
After he had grown accustomed to failure and forgotten the feeling of disappointment, had the dawn of reversing the past finally appeared?
A smile appeared on the face of the man who had lived in the shadow of causing Kallen's death for five hundred years.
"Honestly, it is very dangerous to use the Spiritron Transfer device in this world."
The young man who had brought the device to the Honkai world looked at the Schicksal Overseer and said.
"It is indeed very dangerous."
Otto smiled and nodded.
This was a fact.
The Honkai world was connected to the world bubbles of the Sea of Quanta. Once the past of the Honkai world changed, some of the world bubbles adjacent to the Honkai world in the Sea of Quanta would also be affected, and then they would interfere with each other, creating variables.
Furthermore, the Honkai Consciousness, that entity that arranges corresponding Herrschers according to the development of human civilization, would very likely create a Herrscher with authority over souls or a Herrscher who could interfere with time because of this.
If one thing went wrong, human civilization would get a "GG" and enter the Third Era.
Otto, who knew very well that the establishment of an organization called Chaldeas would bring an unprecedented crisis, calmly analyzed the possibility of human extinction.
But was that sort of thing important?
A mocking smile appeared at the corners of Otto's lips.
He, who had continuously added to his sins and committed countless evil acts to resurrect Kallen, how could he care about those possible crises?
"However, I think, my dear friend, that you have already brought the tool of time travel before me. If I were to abandon the establishment of Chaldea because of some small danger, wouldn't that be a great disservice to your goodwill, my friend?"
With a light and dismissive tone, the man named Otto categorized the possibility that could lead to human extinction as a "small danger."
"Feel free to list the materials needed to establish Chaldea."
The Overseer, who knew very well that the friend before him was helping him only to get something from him, chuckled lightly.
Since he came seeking profit, then he just needed to give him enough benefit.
"As your friend, I, Otto Apocalypse, am willing to provide all possible assistance for your experiment."
