The Humanity Order Continuation Security Organization, Finis Chaldea.
An observatory built to survey all of Earth from the void of space.
It was a research institute and observation station that gathered researchers from every field, regardless of magecraft or science, all for the sake of ensuring that human history could continue, long and resilient.
However, that was the Chaldea of the Type-Moon world.
The Chaldea that Li Zihan had established could not, of course, compare to that black-tech conglomerate.
But because the Honkai world lacked the "Quantum Record Strap"—that disgusting mechanism that constrained the unfolding of worldlines—the Chaldea Li Zihan built actually had a far greater potential to influence the world than the black-tech observatory of the Type-Moon world.
As long as he initiated a Spiritron Transfer to the past, he could alter history as easily as smearing paint on a blank sheet of paper.
Of course, the price was also quite steep.
A Herrscher symbolizing Time would sooner or later be born because of this. The Sea of Quanta would be stirred into turmoil by the main world, and the world bubbles adjacent to it would begin to influence each other.
Perhaps other Herrschers would even be born as a result, Li Zihan mused.
The domains Chaldeas touched upon were not limited to just time. Once the Will of Honkai had completely read its data, it could very well give rise to Herrschers corresponding to multiple fields, such as Mysticism, Imaginary, and the Soul.
But that had nothing to do with him.
If he were to be defeated, the worst that could happen was that he would take those connected to him and leave.
That was the thought process of the young man who, in truth, had barely considered resisting the Honkai.
Li Zihan's attributes as a magus were Imaginary and Wind.
Those with the Imaginary attribute love to explore the unknown, while those with the Wind attribute are never settled in one place.
A person's attributes will influence their temperament.
With such a combination of attributes, Li Zihan was a natural-born explorer. He obviously felt no particular attachment to the Honkai world, which was merely one stop on his life's journey.
Honestly, if it weren't for the girls here who were connected to him, he would have long ago thrown caution to the wind, wreaked havoc, scraped the land clean of anything valuable, and then made a grand escape.
It was hard to say if the young man was even serious about resisting the Honkai. He was now pulling along Seele, whom he had just found in the school building, and following Rita's lead into the control center of Chaldeas.
There, the strongest Valkyrie with long golden hair and the bishop with long green—bah, I mean—golden hair stood, having already waited for some time.
"Are we starting the experiment so soon?"
The young man, who had been on a date with Ana just moments ago only to be suddenly dragged here by Otto's proxy, Rita, let out a sigh.
With Otto Apocalypse personally overseeing the project, Chaldeas had been completed even faster than imagined.
This was understandable.
Thanks to the incredible energy source known as Honkai energy, construction in the Honkai world was already fast. With Schicksal's top boss personally acting as foreman, the construction speed of Chaldea had naturally skyrocketed.
"My dear friend, it seems I have disturbed your rest."
The handsome man, who had written to Li Zihan the very moment Chaldeas was completed, looked at the young man's seemingly unhappy expression and smiled faintly.
"You did, a little."
Li Zihan, who clearly preferred sticking close to girls over shooting the breeze with Otto, dispensed with all pleasantries.
His date with Ana wasn't even finished.
Mei and Kiana were also about to return, and they would probably want to hold him accountable. He needed to do away with Gilgamesh as soon as possible and take his eyes, which were guaranteed to see the final outcome as well as the immediate future.
Only then could he use his save-scumming methods and future sight to appease and conquer the girls who might turn dark, all in a cheat-like fashion.
He was a very busy man.
And now, Otto wanted to drag him off to conduct an experiment...
Li Zihan felt the urge to draw Jizo Mitama and send this man, whose consciousness resided in a Soulium body, to the Western Paradise.
"Honestly, after receiving the notice, it took a great deal of effort to suppress the urge to tear it to shreds."
It was hard to imagine anyone daring to speak to Otto in such a tone.
Otto Apocalypse was the most arrogant and conceited man in the world. He usually appeared gentle and refined, but once provoked, he would bare his fangs.
Speaking to Otto in Li Zihan's tone was incredibly dangerous; one could very well receive a physical account ban.
However, not a single trace of displeasure appeared on Otto's face.
"It is truly a shame to have disturbed you, my friend."
"However, today's situation is somewhat special. I hope you can participate in the experiment ahead of schedule."
The handsome man smiled, and in a casual tone, he stated a reward that even Li Zihan could not ignore.
"As an apology, after you complete the first experiment with Chaldeas, I can lend the Apocalypse family's Śarīra to you, my friend, for a period of time."
As a descendant of the Previous Era's super-soldier, Su, the Apocalypse family safeguarded their ancestor's relic—what they called the Śarīra of infinite wisdom.
And the true identity of that Śarīra was the Key of Revelation.
The First Divine Key, which stored all the knowledge of the previous era and could simulate every other Divine Key except Jizo Mitama.
—The Void Archives.
Li Zihan was very interested in the Divine Keys, a fact Otto knew well.
Since he liked Divine Keys, then he would give him a Divine Key as a gift. For Otto, trading a Divine Key for Kallen's earlier return was clearly a worthwhile bargain.
"I understand."
The young man, reluctantly accepting this reality, took the hand of a slightly blushing Seele and walked to the side of the Honkai world's strongest goose.
"Then let's start the experiment early."
"I will retrieve the soul of Saint Kallen as quickly as possible and have her resurrected in this world."
"I am truly grateful."
The man's smile, having received the answer he wanted, carried a hint of release.
Kallen could finally escape the fate of being tragically devoured by a Honkai Beast.
His nightmare was finally coming to an end.
"No need for thanks. It's my duty."
The young man, who was indeed just doing a job for pay, said this before turning his gaze to the strongest goose in history beside him.
"Miss Bianka, do you have any questions about this experiment? If you do, I would be happy to explain."
"I have already been briefed on the details of this experiment, Director."
The girl named Bianka Ataegina—Durandal—gave a solemn salute to the young man whom Rita had evaluated as a "perfect person."
She believed that this person, who could conceive of both the Human Order Security Project and the Artificial Herrscher Project, possessed qualities worth learning from.
"I will be in your care for the upcoming operation."
"And I in yours, Miss Bianka."
The young man, who had absolutely no intention of going to Europe, replied to Durandal with a smile.
