"Alright."

Without much hesitation, Li Zihan opened his mouth and agreed to Reines's request.

Although he didn't understand what his future self had done to get involved with this pleasure-seeking demon, since she mentioned love, she must be someone related to him.

At this thought, Li Zihan's mood brightened considerably. It seemed that in the game between him and Alice, he was the winner. If Alice had won, he wouldn't have been able to flirt with other girls.

"Well, thank you very much for that."

The delicate-faced, blonde girl smiled, her expression light and cheerful.

"Now that my private business is settled, it's time to talk about official matters."

"What official matters?" Li Zihan asked.

"I came here at the Doctor's request."

The girl, who had appeared in this world as a Pseudo-Servant, spoke.

"Chaldea is willing to share the data for 'Trismegistus' with you, on the condition that you agree to a few things."

"The people from Chaldea are willing to share the data for 'Trismegistus' with me?"

Li Zihan looked at the girl who seemed to be representing Chaldea, his expression a bit strange.

Spiritron Calculation Engine: Trismegistus

One of the advanced pieces of alchemical equipment that Marisbilly Animusphere, the builder of Chaldeas, had managed to acquire only by holding a contract from the Atlas Institute, which allowed him to unconditionally request technical support.

Through Trismegistus, it was possible to prove a Master's "existence in a Spiritron sense" in any era, thereby enabling interference with the past.

Without a doubt, this was one of the most advanced alchemical devices in this world.

And they were just giving away the data for something like this?

"Is my future self on good terms with the people at Chaldea?"

The young man, who had considered just coasting through the FGO world line, pondered for a moment before asking the girl who was acting as a matchmaker for her "current self's" fiancé.

"No, my dear, you're overthinking it."

Reines sighed.

"It's because if they don't give the data to you, my dear, you'll just lead a team to Chaldea and take it by force."

In the version of events she was aware of, Li Zihan did exactly that, leading a white-haired man, a squinty-eyed man, and another man who, despite being a blond, gave off a distinct green-haired vibe, to raid them for the data. And then he proceeded to clear a few Singularities for good measure.

"The Doctor's thinking was that it's better to just hand it over rather than wait for you to come and take it by force."

The girl, who had already secured a nominal marriage contract, smiled and then relayed the thoughts of Chaldea's acting director.

"Of course, it's not a free gift. We hope that you will use things like Jizo Mitama less often. At the very least, do not use that weapon's over-limit power up to the First Rated Power and provoke the Counter Force."

Miss Reines had been sent here to resolve the Singularity incident.

At this point in time, which characters could directly cause a crisis for the Human Order?

With almost no thought, the people at Chaldea had determined that the core of this event was a certain individual who had helped them before but had also caused a great deal of trouble.

That is, Li Zihan.

This man was someone who could travel between different worlds and carried a pile of high-risk items. Abusing his power could easily attract the attention of the Counter Force. If nothing else, Jizo Mitama alone was enough to put Alaya on high alert.

If Li Zihan did something bad to provoke Alaya, he would very likely be swarmed by a group of powerful men.

And then...

And then human civilization might just get a "gg" from the destruction wrought by the Key of Erosion—Jizo Mitama—unleashed at full power.

Chaldea should have summoned multiple powerful Heroic Spirits to, even if it meant using a certain degree of force, stop him from recklessly using high-risk weapons and prevent a conflict between him and Alaya.

Unfortunately, this man possessed an armament called the Oath of Judah.

In the Divine Grace Domain, which could suppress most forms of energy, Heroic Spirits, whose bodies were composed entirely of magical energy, were rather pathetic. It was a hard counter that was devastatingly effective against divine beings, a truly despair-inducing fact.

Therefore, the acting director, Dr. Romani, had chosen to send Reines to persuade this man who was practically a civilization-ender.

Reines thought about it, requested the data for "Trismegistus," and then promptly performed a Rayshift.

"Well, that's quite troublesome."

The young man, who had originally planned to use Jizo Mitama on Brother Red A, sighed. If that was the case, he would just have to use a gentler method to get Brother Red A to help him.

"So, my dear, are you willing to agree to the terms proposed by Dr. Romani?"

The girl, who would have given him the data regardless of whether he agreed or not, chuckled and spoke.

"Well, that can't be helped."

Li Zihan, who wasn't unable to persuade Red A but was just too lazy to, shrugged his shoulders. It was free data for Trismegistus; it would be a waste not to take it.

"I agree."

"That's wonderful."

The girl, who had completed both her private business and the mission assigned by Chaldea with just a few sentences, clapped her hands, a smile on her face.

"Yes, it is wonderful."

The young man, suddenly a bit curious about what he had done on the FGO timeline, also smiled.

After this Holy Grail War is over, I'll use the Grail to reproduce Trismegistus and complete the green-haired man's request, then I'll go check out the FGO world line.

The young man, who might just build a Chaldeas in the Honkai world, thought to himself.

Go to Vienna five hundred years ago, take Karen's soul at the moment of her death, and then return to the twenty-first century.

"Master, the situation has changed slightly."

Just as Li Zihan was contemplating what to do next, Karna's voice reached him through their contract.

"What's the problem?"

The young man, who was almost certain of victory, narrowed his eyes and asked.

"Without releasing my Noble Phantasm, I cannot gain an advantage in this melee."

Because of his Double Summon, Karna, who possessed the strongest combat power of the three powerhouses, was sometimes drawing his bow and shooting arrows, and other times swinging his spear. Even so, his situation was not optimistic.

Gilgamesh, who had almost been taken down by the rampaging Big Doggy's spear, had entered his serious mode after taking a potion. The heavily wounded Mad Dog had also become even more berserk after being injured.

Karna wanted to withdraw, but the two Servants who had started fighting because of his guidance had both noticed this and were intentionally holding him back, preventing him from escaping.

"Please allow me to release... a somewhat dangerous Noble Phantasm."

For a rare moment, Karna, his blood pumping, requested permission from his Master. Both Cú Chulainn and Gilgamesh were powerful warriors worthy of him fighting with all his might.

"In matters of combat, do as you see fit."

The affirmative answer reached Karna's ears.

"That is... wonderful."

Above the ruins of the Tohsaka estate, the noble son of the Sun God raised the spear in his hand.
