Every Master who participates in the war knows that the "Holy Grail" will descend at the end of the Holy Grail War, but they do not necessarily know where it will descend.
Only the heads of the "Three Great Families" and the supervisors of the church know that the "Holy Grail" will not descend on its own, but requires a summoning ceremony to be held in a place with sufficient spiritual power.
In the land of Fuyuki, there are four places with enough spiritual power to be used as the locations to summon the Holy Grail.
The preferred spiritual vein node is Mt. Enzo, which has a large natural cave called the "Dragon Cave". The Holy Grail based on Justisia is set up here. As a secret altar known only to the three great families, this has been the best place since 180 years ago.
As the land provider, the Tousaka family originally had the priority to use the best spiritual vein node as their base, but the magic power in Enzo Mountain was too strong to be a place to cultivate the next generation of magicians, so they settled in the second spiritual vein node, which is now the Tousaka residence. Although it is not as good as the Holy Grail, it has enough spiritual support for the Holy Grail to descend.
The third spiritual vein node was originally given to the Makiri family who moved here, but it was later found that the land's spiritual energy was incompatible with the family's attributes, so the Matou residence was moved to another place, and the original spiritual vein was occupied by the later intervened Holy Church, which is now the hill where the Fuyuki Church is located. Although it is located in the suburbs of Shinto across a river, far from Enzo Mountain, the spiritual level there is not inferior to the second spiritual vein.
The fourth spiritual vein node did not originally exist on this land, but was adjusted through magic processing, resulting in the accumulation of subtle changes in the flow of the great source of mana (MANA) for more than a hundred years, which gathered at a certain point, that is, the spiritual land that was created later. After subsequent investigations, it was confirmed that there was enough spiritual power here to hold the ceremony, and since the third Holy Grail War, some people have used this place as a candidate location. Now this location is located in the center of the new residential area of the new city, and a new citizen activity center has been built.
Shinji naturally chose "Enzoyama" as the location to summon the Holy Grail, not because he was obsessed with first, second, or third place, but because it was the only choice.
The second spiritual vein node is Tōsaka Tokiomi's base, which is not suitable.
The third spiritual vein node is the base of Toshiomi Tōsaka's allies. Although there is no one in the church now, now that Kotomine Kirei has left, there is a high possibility that it will fall into Toshiomi Tōsaka's hands, which is not appropriate.
The fourth spiritual vein node has a lower spiritual level than the other three, and is located in a densely populated area. At the end of "Fatezero", Kotomine Kirei chose to summon the Holy Grail here, which resulted in a huge fire and killed countless people, including the protagonist of the Fifth Holy Grail War, Shirou Emiya's biological parents. Anyone with a normal outlook would not choose this place.
Although Shinji has already taken two lives, his world outlook, values and values have not been distorted. His choice from beginning to end has always been "Mt. Enzo", or to be more precise, Ryudo Temple on the top of Mt. Enzo.
In addition to being the most spiritually qualified and the most suitable for summoning the Holy Grail, choosing Ryudo Temple also has two other advantages:
First, it was sparsely populated. Liudong Temple was not a popular temple. The monks in the temple practiced hard, there were not many of them, and they did not understand the mystery. Scathach only took half an hour to hypnotize all the monks and gathered them in a room farthest from the summoning ceremony to avoid being affected.
Second, it is easy to defend but difficult to attack. The reason is certainly not because the floor is hard enough. The fact that the floor here is called EX hardness like the Fuyuki Bridge is just a joke. The floor here is just an ordinary bluestone slab, and the hardness is not even E. The real reason is that there is a strong barrier around Ryudo Temple, with Ryudo Temple as the center, covering the entire Enzo Mountain. The function of the barrier is to powerfully drive away spirits. Servants who are spirits can only enter from the shrine entrance. If they set up defenses at the mountain gate, it would be really a one-man defense against ten thousand men.
In fact, in the Fifth Holy Grail War, Caster Medea did just that, sending the illegally summoned pseudo-Assassin Sasaki Kojiro to guard the mountain gate. No one could enter Ryudo Temple unless Kojiro died or released him.
As night fell, Shinji, Scathach, Kariya, Lancelot, and the two captives, Maiya and Irisviel, gathered in the guest room next to the main hall of Ryudo Temple. Shinji, Kariya, and Scathach analyzed the possible situations that might arise tonight based on a map of Fuyuki City.
While arranging the rituals for summoning the Holy Grail and collecting magic power, Justisa selectively explained the whole story to Irisviel and Hisau Maiya.
Following Justissa’s narration, Irisviel and Maiya, who could only move their heads, fell into unprecedented panic.
The Matou family has two masters, and the two servants are the unfathomable Scathach, and Berserker, whose combat power is rated at the same level as Archer (mistakenly).
Lady Justisa did not disappear completely, but was still lurking beside her, watching her every move.
The one possessed by Justisa was Assassin's Master, a true monster.
He knew Emiya Kiritsugu and Saber very well and could predict almost all of their possible actions.
He knew the effect of releasing the real name of "Avalon", which was information that neither Irisviel nor Emiya Kiritsugu knew.
He knew Kiritsugu's exclusive magic "Inherent Time Control", knew the principle and effect of "Origin Bullet", and made targeted defenses in advance.
He also knew Archer's true trump card and developed a battle plan based on Archer's character weaknesses.
He has already spread a big net and is waiting for three more pairs of master and slave to come to him.
What makes the two feel even more desperate and incredible is that the Holy Grail that Kiritsugu relies on to achieve miracles and fulfill wishes has been contaminated, and the only way to fulfill wishes is to destroy them. If Kiritsugu really wishes to eradicate war, then a huge disaster will be waiting for mankind - there will be no war if all humans die.
If someone else had said this, Irisviel and Maiya would not have believed it, but the person who said this was the builder and core of the Greater Holy Grail system, so they had no choice but to believe it.
The two tried hard to ask Yustiza to tell Kiritsugu the news, but were stopped by Shinji.
The reason is simple -
"Kiritsugu's character is firm if you want to put it nicely, and stubborn if you want to put it bluntly. He won't stop until he realizes the true nature of the Holy Grail. With Emiya Kiritsugu's ability, it's only a matter of time before he reaches this point. By that time, he will realize the true nature of the Holy Grail. After that, whether Emiya Kiritsugu will collapse because his dream is shattered depends on whether you two ladies can keep his heart."
“I can only rely on Miss Maiya, because by that time, I will have already—” Irisviel’s expression was gloomy.
"You won't die." Justisa gently placed her hand on Justisa's forehead. "You will survive like me. You will live with your husband and daughter, watch your daughter grow up, and you will tell your husband those words."
"Lady Yustisa, what you mean is—" There was a sudden turn of events, and Irisviel could hardly believe her ears.
"Call me sister." Yustisa emphasized again.
"Justisa...sister..."
"That's right, let me, the elder sister, give my younger sister a meeting gift."
A brilliant and sacred light illuminated the entire room. It was a miracle above magic, it was the brilliance of the third magic.
PS: It is safest to keep Irisviel and Hisahi Maiya under Scathach's nose. Even if they know this information, it will not cause any waves.
PS2: It is impossible for the Holy Grail to destroy humanity, because the Guardian of Alaya will eliminate this factor before it starts. For details, please refer to the event of "Fategraezero". Xiao An ran out of the Holy Grail and found that Kiritsugu, who became the Guardian, was waiting outside to cut him.
