The method that Emiya Kiritsugu said is actually very simple, the two masters cancel the contract with their own servants at the same time, and then sign a contract with each other's servants. It stands to reason that the contract between the Servant and the Master is not self-canceling, but as the Einz Bellen family, who built the séance ritual in the Holy Grail War, will they leave themselves a little privilege in this? But the biggest variable in this process is that the Servant has untied the only shackles for them- After the spell, whether in magic or physical strength, the servants are not comparable to ordinary magicians, and most of the people who can be summoned are legendary heroes, and few are willing to be bound by ordinary people who are not as strong as themselves. It was these unknowns that led Einzberger to mothball this technology because the conditions were too harsh and the practicality was too low.

But now Einz Belen has a rare possession of two servants, and one of them is also known as the strongest rank "Saber", and this strongest servant also has a very strong desire for the Holy Grail and restraint against himself, and should not reject this opportunity to improve his own strength and be with a better master, the focus is Caster. Emiya Kiritsugu rubbed his eyebrows, Caster was an unexpected servant, and he didn't know his past at all, so it can be said that everything about him was unknown, and he thought he could get some useful information from his memories, but he didn't want to put Alice Phil in danger instead. All that can be said now is that this Caste will not go awry at the critical moment, or that Saber will be able to keep him at bay.

At night, it was still the Great Hall of Heroic Spirits, and the two began to exchange servants. There was no surprise expected by Emiya Kiritsugu, and not only did Caster not appear to have rebelled against the master, but he behaved better than Saber - although Saber had agreed to exchange the master, she would never accept the "knight king" as a commodity, on the contrary, John did not have this kind of self-esteem, and after hearing about this method, John was very expectant. Although John didn't care who his lord was, somehow, John always felt that if he followed Emiya Kiritsugu, he would see a lot of interesting things.

"That's right. In the middle of the termination, John suddenly spoke up and said to Emiya Kiritsugu: "When we reconnect later, there may be a situation where my magic will flow into your body, try not to accept them, you know? Emiya Kiritsugu raised his right hand and chanted a mantra and nodded slightly. I don't know what to expect, but since John has already explained it, it's better to follow it as much as possible. After all, according to what I saw last night, that amazing magic might fill his magic circuit in an instant, and what kind of damage that aggressive magic power would do to his magic circuit, even if he didn't have to feel it himself, just imagining it would make Emiya Kiritsugu face up to John's proposal.

At the moment of signing the contract, the magic that would have flowed to Emiya Kiritsugu's body was controlled by John, and the light was only slightly revealed by a trace of aura that made Emiya Kiritsugu feel threatened. Fortunately, John didn't play a magic blast halfway through, but continued to complete the contract with Emiya Kiritsugu very peacefully.

According to custom, after signing the contract with John, Emiya Kiritsugu is bound to check the attributes.

Noble Phantasm:

？？？

...... What are these things? Emiya Kiritsugu looked at this attribute, and couldn't hide a desire to complain. It's not that I haven't seen other Servant attributes, such as Saber, who has now become my wife's Servant, so I feel abnormal. If strength, agility, intelligence, and luck can still correspond to the previous strength, agility, magic, and luck, then what is left? And there is no evaluation of the Noble Phantasm, and even the Noble Phantasm is still invisible. If it weren't for the excellent production of positions and spellcasting props, and having seen Caster's real spellcasting and physical fitness, Emiya Kiritsugu would not have believed that he was a very powerful servant. But well, it can be seen that these attributes have been divided into very fine, and these numbers don't feel low, at least as a servant should be enough.

Turning his head to look in the direction of his wife, Emiya Kiritsugu could feel that Saber preferred the gentle Alice Phil to follow him. And Calder, who is now his own servant, still looks indifferent, and after the contract is completed, he has taken out the previous summoning book and continues to watch, as if he cares about the previous failure. Well, you can see that there is no objection to this result.

Thinking of this, and calculating that the time was almost up, Emiya Kiritsugu called everyone and said, "Prepare yourself, we will go to Japan in two days." But Caster and I won't be with you this time, Ellie. This time, you and Saber acted together, and it was the Master and Servant on the surface of Einzberger who attracted the attention of the other groups, and then Caster and I arrived in Fuyuki City to secretly support you. Alice Fell knew about the plan, which had been agreed upon before summoning Saber, only this time Caster would act with Emiya Kiritsugu.

It's a good plan, the two groups of people act separately, one bright and one dark cover each other, it can indeed play an unexpected situation, and because most of the servants summoned by the corresponding have the desire to complete, there is little possibility of joining forces, if there are two servants in the same camp, there may even be mutual restrictions resulting in a decline in combat power, so few people would have thought that this time Einz Belen would have two pairs of master and slave to participate in the battle. After hearing Emiya Kiritsugu's words, John also thought about the secret and nodded slightly.
