“…… I see, so I'll leave it to me to modify the Holy Grail system. The passage through which the Einzberren family replenished the magic of the Great Chalice a year ago could also be used by me, and if you had not obtained the key to open the system, even I could not guarantee that everything would be ready in a day or two.

Until the transformation of the Great Chalice is complete, our Archer must stay here to protect me, and it will be up to you to fight or join forces with other Servants.

Although we intend to extract as much of the leyline's mana as possible this time, in order to avoid the leylines being depleted, we will need to 'recycle' the mana of at least the three Servants except the Avenger into the Holy Grail, which will require you to work hard. ”

"No problem, we'll leave the rest to us, but we'll try to postpone the tricky battle until you're done."

"Opening the 'hole' to the 'root' is actually a passage opened when the Servant's soul returns to the 'Throne of the Immortal' located outside the world, and the vast amount of magic accumulated in the Holy Grail is used to secure this passage, thus creating a door to the outside world.

If you want to open that 'hole', a dead Servant soul is a must, and my wish requires nothing more than a huge amount of magic, so you are fighting for your own wishes, and I am just helping you by while fulfilling your own wishes. ”

"We won't always trouble you, but the enemy is the enemy of both of us, and we have provided an important key to hacking the Holy Grail system......"

After determining the general direction of the "Holy Grail Sealing Project", Caster Medea and Saber Ji Feng had a less heated discussion on the specific work undertaken by both parties, and finally reached a consensus and quietly left.

When Rin Tosaka and Libra Gold Saint Seiya, who seemed to be different from the "original" painting style, completely disappeared from their sight, Yanagito Isseri, whose expression was really complicated, finally lowered his voice and questioned Medea:

"Haven't we become allies with Tosaka! But why did you hide Marta's existence?

And Marta followed them so blatantly...... What's going on? Can't they see Marta at all? ”

"Ahh......h Ichisei-kun, don't you yourself understand why I'm doing this?

Although I don't intend to tear up this covenant that is very beneficial to me. But it is only natural to send spies to spy on them to prevent our allies from plotting against us behind our backs. ”

Hearing Yanagito's not very harsh questioning, Medea turned around and asked him a funny question, and then explained to him that Marta was a legendary female spy? Harry's special abilities:

"The strength of the Assassin is the weakest of all the Servants, if it is an assassination system, there are still some lethal moves, and the Assassin of the spy system is almost completely useless in frontal combat. Even the MASTER, who is a human, may not be able to die.

However, such an assassin is not completely devoid of a chance to win. Marta? Harriet has almost all of her lowest abilities, but she has an A++ level espionage skill. This skill does not shield the aura, but makes people not feel the hostile aura, reaching the level of A++, as long as no one in the friendly camp reports it, it is impossible for the other party to detect that they are hostile.

So Issei-kun don't be soft-hearted and go to the inform, although they can't do anything to me and the goddess Artemis if they know, but they may not be so polite to spies. ”

"I ...... Of course I'm not going to snitch. But I want you to fulfill your own wishes, and at the same time keep your promise to help the other person fulfill their wishes. ”

As a glasses character. Even if Yanagito Issei is righteous, he will not be stupid enough to believe others without doubt like a hot-blooded character, so he actually approves of Medea planting an eyeliner next to the other party in his heart.

It's just that he not only doesn't fully believe in the female fox of Rin Tosaka, but also doesn't fully believe in Medea, the "witch of betrayal". Although he didn't understand magic at all, he could also see that the plan made by the Tosaka side and his side just now was decided by Medea, and if she didn't want to waste the magic power that could allow her to stay in the world for a longer time, she just had to drain all the magic power when she finally implemented the plan and didn't open any doors for the Tosaka side. And she doesn't have to bother with the matter of "saving" Jack the Ripper, anyway, as long as the evil spirit is sealed.

If Tosaka's side knew that Caster on his side was actually the "witch of betrayal" Medea. Surely I dare not believe in her credibility or even her temperament so much. But before Medea was really treacherous, Yanato Kazunari still wanted to try to believe her. After all, she is indeed deeply affectionate to Soichiro's brother...... Something like that, so he'd just watch it now.

On the other side, Rin Tosaka, Joan of Arc and Ji Feng and others quietly walked out of the mountain gate, and after going down to the foot of the mountain, Rin Tosaka, who had almost let Ji Feng "turn over as the master" just now, finally opened his mouth to question the alliance agreement he reached with Caster:

"Na! Ji Feng, do you believe that Caster who didn't even show his face so much?

I don't care about the Holy Grail, though. But if we give full control of the Holy Grail to the other side, they can drain all the mana without opening the 'hole' for us, and even drain the leylines as well.

With such a huge amount of magical power, even if she is a weak Caster with a weak ability to fight head-on, she should not be afraid of you and Berserker...... Even with the combined attack of Miss Joan of Arc. What's more, we still enter her magic position to fight it.

YOU DON'T HAVE TO TRUST THE TWO MASTERS ON THE OTHER SIDE JUST BECAUSE THEY ARE MY CLASSMATES AND TEACHERS, IN FACT, YANAGITO IKSEI HAS ALWAYS BEEN QUITE HOSTILE TO ME, AND KAZUKI-SENSEI ...... It doesn't seem that simple. ”

"It's rare that the four Servants on both sides of us are not attached to the Holy Grail itself to reach such a pact, and if the other party's Caster is smart enough, it shouldn't ruin this win-win situation. I'm just afraid that she's not smart enough but she thinks she's smart and always wants to take all the benefits to herself, then we'll only have one battle at that time.

As for why I dare to believe that the wishes she told us were not lies...... Just take it as a man's instinct. ”

"Male, man's intuition...... Can you be serious at this time? ”

"I've always been serious!

But Joan of Arc, we're talking about modifying the Holy Grail system and ending the Holy Grail War once and for all, so why don't you, the Ruler, object to it in the slightest? ”

"Huh? This......

I......

I don't know. (To be continued.) )
