[Comprehensive] Self-cultivation of the villain master

In Fuyuki Church, Kotomine Chirei turned his back to the direction of the door, and stared at the statue in front of him with both eyes. The expression on his face couldn't tell what it was, but it wouldn't make people feel happy.

A golden light flashed, and a boy with brown hair and green eyes appeared behind Yanfeng Qili out of thin air. He glanced at the bow in his hand, but did not step forward.

"Acher, how about Einzbern?"

Yanfeng Qili turned around and asked his newly summoned servant with a blank expression.

Because he has a lot of command spells in his hand, even if the previous two servants were defeated, as long as the other masters have not had time to summon new servants, he can use up all the command spells given to him by Kotomine Risho at once. Summon new followers again and again.

"There's nothing unexpected about it."

The servant named Acher's tone was cold, and he didn't regard the person in front of him as his Master at all.

Faced with such an impatient attitude from his follower, Yanfeng Qili waved his hand, and the other party turned into golden shards of light and disappeared immediately.

"Tsk, I thought I could summon a servant who would not lose to Gilgamesh, but I didn't expect—"

The heroic spirit that has not been recorded in history and is not known to anyone is named Aiolos. Since there is no corresponding legend, it is very difficult for Kotomine Qili to use.

The power of heroic spirits comes from people's beliefs, and what people recognize are the treasures of servants. However, not only has Kotomine Chiri never heard of Acher's name, he doesn't even know what abilities he has.

Worst of all, he could see that the opponent's stats were extremely low.

"Well, it's fine if we can lure Emiya Kiritsugu out."

Even though he still doesn't know what he is looking for and what his wish is, Kotomine Chirei believes that as long as he can confront that man Emiya Kiritsugu head-on, he will always be able to find the answer.

After leaving the Fuyuki Church, Aiolos put away the golden bow in his hand.

Yanfeng Qili is not so easy to deceive. To achieve the condition that "the servant standing in front of you" is a "newly summoned servant", Aiolos has used all the spiritual abilities he knows, because It won't have much impact on this man after using it for a short time. As for the future... anyway, he can't see it.

A gust of murderous wind blew past, and Aiolos avoided it easily. Looking at the blue-haired boy with a gloomy face not far away, he couldn't help but smile.

"What a rude way to say hello, Astra."

"Aiolos, I haven't settled the account with you before!"

Astra looked at the other party's extremely confused look, and sneered endlessly.

"Saber, haven't you forgotten what you did before?"

"Well, let me think about it..."

What Astra didn't expect was that the other party really thought about it seriously, and judging from the way he tilted his head and frowned, he still couldn't remember it for a while? !

After a while, Aiolos blinked and said, "I'm sorry, I still don't remember what I did to apologize to you."

"You caused my body and soul to be separated, do you plan to let it go?"

Hearing this, Aiolos showed a look of sudden realization: "This matter really has nothing to do with me. You may have forgotten that the fit between your soul and body itself is very low, otherwise it will not matter." Something soul-splitting is going to happen."

Meeting Astra's puzzled gaze, Aiolos shrugged and said, "Didn't you have it once before? You obviously kept your consciousness, but found that it was another consciousness that controlled your body..."

Astra's expression froze: "...how did you know? Could it be that you were nearby??"

"Indeed, before Yanfeng Qili was settled, I did intervene in the battle between you and Rider, but it was through the hand of that child named Weber, and I didn't intervene directly. Anyway, that power belongs to him in the future, so give it now. It won't harm his body if he uses it once, and I don't need to do it myself, and I can seal that crazy part, which is a good result for you and me."

"You know me before amnesia?"

Astra found that not only the god named Naiji, but also Agas, and the servant in front of him seemed to be very familiar with him, so it was only possible that they knew their former self.

Aiolos' expression changed slightly, and he immediately pretended not to know anything.

"I don't know you, it's just that Agas told me. As for how he knew...you can ask him. Oh, but this is after you return to Chaldea."

"...Do you dare to look me in the eyes and say that?"

Deliberately ignoring Astra's words, Aiolos took out a small box and handed it to the resentful Caster.

"I have no intention of fighting with you, I just came here to give you something."

Astra took the box, opened it, and found something like a drop of water.

Seeing Astra's blank face, Aiolos explained: "This is the power of the ocean that can purify everything. As long as you release it, you can wash away the black mud in the Holy Grail."

"It's obviously a tough battle, why do you say that...it's so easy?"

Astra knew very well that what he was about to face was the "evil in this world". He was reluctant to imagine what it would be like to face the whole world's malice, but he had to face it.

Therefore, he does not agree with Aiolos's frivolous statement.

"In the final analysis, the malice of the world is actually the reversal of the goodness of human beings. It is not something that cannot be eliminated. It's just that each person's acceptance is different, which makes people feel that it cannot be dealt with."

"The method of use is similar to the concept dress, which is equivalent to the physical dress."

Staring at the drop-shaped crystal in his hand for a long time, Astra hesitated and said, "Using this...can really purify that thoroughly?"

"Yes."

After getting the guarantee, Astra was relieved. Although he had thought of various methods for the opponent's Holy Grail before, such as dragging out the anti-hero inside and beating him up... Now that Aio Ross provides a simpler method, which is also a guarantee of safety for him.

"Why do you help me so much?"

Astra is not a fool, except for the seemingly fatal arrow from the other party in London, basically he did not do anything excessive to him and everyone in Chaldea, instead he brought some suitable servants to him. to their side.And now, he came to this time and space deliberately, just to give him something that can purify all things.

Who would believe it if it was just a coincidence?

Aiolos thought for a while, and suddenly said: "Perhaps, I want to see changes."

Astra: "??"

"No, it's nothing. Irisviel doesn't have much time left, so hurry up and perform the ceremony."

Leaving this sentence, Aiolos disappeared, and Astra, who wanted to ask a lot of questions, had no direction. Instead, Merlin beside him, seeing that the servant had left, hurriedly appeared to remind Yu host.

"Aiolos is right, Master, you can really prepare."

Knowing that Aiolos was not Yanfeng Qili's assistant, Astra immediately rushed to the church, knocked the latter unconscious, bound him and threw him into a different dimension, and then brought Merlin back to Einzbern.

Throwing the unconscious Kotomine Chirei at the door, Astra asked Emiya Kiritsugu to teach him to be a good person, and then ran to the basement of the castle without looking back.

In the past few days when Astra was looking for Aiolos, all the required materials have been prepared.

Through the summoning array made up of gemstones of different colors, Astra held the purification crystal tightly in his hand, and whispered: "Come to me, Holy Grail."

In the sky, a huge black object quietly appeared.

Sensing the coming of the Great Holy Grail, Astra walked into another dimension and appeared in the sky.

"Purge the world of all evil."

Immediately, a large amount of ocean power surged out of the pure blue crystal, and in an instant, it rushed into the big black golden cup. With the scream of pain, the originally ominous Holy Grail gradually revealed its holy meaning. breath.

"Make a wish, Irisviel."

Through the connection between the Servant and the Master, Astra said to him.

"My wish is..."

The Fourth Holy Grail War ended, and the winner was the Caster group. Because the servants took away the Great Holy Grail, the Fuyuki Holy Grail ended.
