Heroic Spirit: I, Shinji, have tried my best.

In the Einzbern castle, Illya and two maids gathered in a circle, staring at the small bottle on the table...

Lijielit: "Who's coming?"

Sera: "Let me and Lijelite do it, Miss, don't try it!"

Illya: "It doesn't matter. He won't harm me in this way..."

Sera: "No! It's not worth the risk, and if something goes wrong with you we'll lose our lives too."

Illya: So?

Sera: "Let Lijelite come."

Lijielit: “Huh?”

After leaving, Shinji returned to his base at the foot of the mountain behind, where various experimental equipment were placed. He had combined his own Sage Cells with the artificial human technology to produce high-concentration Sage Cells, whose effects were even better than Hashirama's cells, which were the bottle given to Illya.

However, this technology was originally intended to be used on Sakura, but it failed, and then he tried to use gene replication to create a pair of Mangekyō Sharingan to evolve him, but it still failed, as he could only create normal eyes even though the genes were exactly the same.

Although the experiment failed, at least the materials left behind are enough to extend the lives of Illya and the other two. It's a pity that he may not be able to witness the power of the Rinnegan.

"boom!"

A puff of white smoke dissipated, and a large pile of experimental equipment was sealed in several small scrolls. These things cannot be destroyed by the aftermath of the battle.

After packing up everything, he returned to Ryudo Temple. It was quiet all around. Sakura and the others had not returned yet. Sitting back at the tea table, Shinji suddenly found that he seemed to have nothing to do... He had been busy with the Holy Grail War and his private life was almost zero.

"This is really..."

So when Sakura and her group came back with a bunch of shopping bags, they saw Shinji lying on the table playing with a teacup with a bored look on his face...

"Nisan, what's wrong with you?"

Sakura immediately stepped forward and asked with concern.

"I think... I should enrich my private life..."

Several people didn't react at first, but then they suddenly realized what was happening. Sakura's face turned red, Medea frowned, and Medusa tilted her head.

“Eh? …Eh!”

……

"Rin, I think I found something!"

"Oh, is it so…"

Toosaka Rin responded perfunctorily to Shirou who looked serious. After Saber woke up, she thanked Shirou for saving her at the critical moment and was still willing to become Shirou's servant. Rin was so angry that she almost terminated her contract with Red A and went to find Saber.

"Do you still remember Yanagido Issei?"

"Remember, isn't he your good friend?"

"A few days ago he told me that he had moved away temporarily, and I didn't pay much attention to it. But when I went to see him later, I found that he had become a little strange, as if... he was controlled by someone."

"And he said that there are guests at Liudong Temple now, so we can't go there for the time being."

"Oh! I didn't expect you to be of some use... But let me ask around."

Rin came to the door alone and called the number Shinji left...

"Hey?"

"We seem to have discovered the enemy's base. Do you want to come?"

"Base? Where is it and how did you find it?"

Hearing Shinji's puzzled voice, Rin suddenly felt a little proud. It was rare that this guy would ask for help.

"It's in Ryudo Temple. I got it from Emiya..."

"..."

"Why are not you talking?"

"..."

"What's wrong? Are you so shocked that you can't speak?"

"…You… Forget it, you don't need to come to Ryudo Temple, this is my base, if you have nothing else, just hang up first."

"…ha?"

Toosaka Rin stood there in a daze, the smug smile on her face frozen, and an atmosphere of awkwardness surrounded Rin.

"Hey! Rin, you're back. How was your investigation going?"

As soon as Shirou finished speaking, a cell phone flew towards his face...

"Emiya, you're a robot!"

A few minutes later, Shirou touched his head which had been punched for no apparent reason.

"So why isn't it right?"

"Don't worry, don't ask, don't pry."

“…What should we do now?”

“…I don’t know. I’ll go ask Kirei tomorrow.”

"Oh... where should I sleep tonight?"

"You and Archer go make a bed on the floor, and leave the bed for Saber."

Red A, who was resting with his eyes closed, was not happy. What does your quarrel have to do with me? Based on the life principle of never standing when you can sit, Red A felt it necessary to fight for a bed for himself.

"I disagree."

"In the name of the Command Spell..."

“…I have no objection.”

In this way, the residents of Fuyuki City lived another day. What a peaceful Fuyuki!

The next morning, Ryudo Temple

"Huh, Nissan, you scared me to death yesterday, suddenly saying something that made no sense..."

Shinji, who was packing his luggage, listened to Sakura's complaints and said calmly:

"I'm going to Einzbern now, you guys should eat first."

"Okay, Nisan, remember to come back early. We agreed last night that we should go shopping together today!"

On the other side, a "big" incident just happened in the Einzbern family not long ago...

"This...this is!"

After Lijielit was injected with half a tube of green potion, a burst of vigorous life energy immediately burst out from her body.

"I feel a little stronger, and my body seems to be much more comfortable..."

“…It seems to be true.”

"Oops!"

"What's wrong, Lijelite!"

Hearing her maid's exclamation, Illya looked over quickly, only to see Lijelite puffing out her chest with a look of helplessness in her eyes.

"My breasts... seem to have grown bigger again..."

"..."

Illya: **

Sierra: *******

Looking at the remaining half tube of reagent, Sera couldn't hold back any longer before Illya said anything.

"Miss, the effect of this reagent is still unclear, and it may have strong side effects. Please let me do the experiment for you!"

“…Sera…”

"And Miss, you are already cute now, there is no need to make any other changes..."

"Sera, calm down..."

At this moment the head maid suddenly woke up. Why did she suddenly lose her mind? Was it really the conspiracy of that man?

"…I'm sorry Miss, I was rude just now."

Illya held the tube of reagent, thinking that the man might really be able to solve their problem.

……

"... Generally speaking, this is a product of highly active biological cells combined with Einzbern technology. I still have a whole can of this stuff, and I am 90% sure that you can reach or even exceed the lifespan of a normal human..."

"I understand. It seems that Mr. Shinji can indeed help us, but I still have a question... Even though the Matou family is one of the three great families, it should have fallen. Why do you still have so much information and knowledge, as well as your terrifying strength..."

"The Matou family does not have much wealth anymore. I got these things through various channels. As for the Einzbern technology... I sneaked into your main family for a while to check some things."

"…You are really bold, and you can't just say something like this…"

"Finally, the matter about my ability involves my privacy, so I am afraid I cannot tell you. The power I have shown now is my full strength, and you probably understand it."

"Okay, I hope we can have a pleasant cooperation in the future. If you need anything, Illya will definitely help you."

Across the coffee table, a big hand and a small hand were clasped together in mid-air, symbolizing that Berserker had officially joined Shinji's camp...
