What happened afterwards was a natural progression. Moved by the fate of their acquaintance and his selfless act of saving others, Shirou collected the remaining souls and prepared to give him a chance, which could be considered as good things happening to good people.
After some investigation, Shirou found that this soul had amazing adaptability to time travel. Thinking of the anime that this guy always mentioned, and Shirou himself had his own layout in the Type-Moon universe, and was also friends with the professional time traveler "Jewel Man" there, he sent him over, and this is how the current story came about.
Shinji was not surprised by this explanation. Shirou was obviously close to "Jewel Man", and many details in his words also showed that he did know himself in his previous life. However, Shinji still had some doubts in his heart.
"Can I ask a question?"
"Ask. At this point, there's nothing to hide."
"Why did you let me travel through time instead of just resuscitating me? Is the latter more difficult than the former?"
"Well, in terms of difficulty, resurrection is similar to time travel, but for individuals, the difference is huge. For example, it is easier to time travel a hundred times than to resurrect you, because you are dead and have no body left, and your soul has lost its carrier."
"From what you said, can you really do it if you want to?"
"It is possible, but the cost is too high and not worth it. Let me put it this way, the underlying rules of each universe are different, and the concept of the Earth is much more complicated than you know. On the Earth where you live and where I was born, extraordinary powers would be greatly limited. On this Earth under our feet, I can save you before you are hit and killed, and even if I die, I have a way to change the situation so that you are not dead. Do you understand what I mean?"
Shinji thought carefully for a few minutes and nodded: "I understand most of it, but... things have changed. Can you do something so exaggerated?"
"It's limited to a small number of universes. I'm a combat specialist, so my major is not suitable for this. I was able to do it because of the help of special equipment."
"Special equipment?"
"Yes, you should have heard of it too - Mooncell, a computer and observation device left on the moon by a civilization far superior to Earth. The space we are in and the fact that I was able to replace Amakusa Shiro Tokisada are all due to the power of Mooncell."
Shinji understood after hearing this.
Mooncell, formally known as Mooomaton, is an energy storage body found inside the moon, a photon crystal with a diameter of 3,000 kilometers. It is an ancient relic made by an intelligent life form different from humans, and the oldest mysterious object in the solar system.
The moon-sized supercomputer, also known as the "Eye of the Moon" and the "Eye of the Earth", interprets everything on Earth. It is a database of human beings, a huge memory that records everything from ecology, history, thoughts, and even souls. It remembers all the past and predicts all the future. Its calculation scale can rival that of a universal computer in the solar system.
It is one of the two most powerful entities known in the Type-Moon Universe. The Fate/Extra series, one of the Type-Moon branches, is centered around it. In a sense, it is the true all-powerful wish-granting machine, the "Holy Grail of the Moon". Using its power, it is easy to change things and create different spaces.
"It's Mooncell? But if I remember correctly, the world line magic of the Moon Holy Grail should have declined a long time ago. Here..."
"I said Mooncell because it's easier to understand. The name Mooncell may be unique to the Moon Holy Grail line, but that computer-shaped Moon Universe exists in all world lines, but it may not be given this name."
"I see. Then what authority do you hold? The 'royal authority' of the master?"
There is a huge fictional world inside Mooncell, and the "royal power" is the supreme dominance of this world, just like the omniscient and omnipotent "only God".
"Neither." Shirou smiled and shook his head. "I have user rights. The 'royalty' of the master is this observation device - it's really uncomfortable, I'd better use Mooncell - that is the permissions and functions automatically generated inside Mooncell. User rights are operated from the outside, just like we usually operate a computer. In terms of permissions, it is still lower than 'royalty'. After all, I don't know and can't change the program code."
"That's an exaggeration. What exactly is the reason for you to go to such great lengths to organize this Holy Grail War? You can't just do it to mess with me, can you?"
The more they get in touch, the more Shinji feels Shirou's unfathomable nature, and the more suspicious and curious he becomes about his intentions.
"I'm not that bored. I have several purposes. Let me start with the one about you. I sent you here, so I naturally don't want you to live too badly. The old man Gem sent you to the Matou family with full consideration. The Matou family is a family between mystery and secularity. If you don't want to be associated with mystery, and just want to be an ordinary winner in life. The Matou family can satisfy you very well. You also know how diligently Matou Shinji changed his girlfriend in the original world line. As for that old bug, it's not worth mentioning because he has the support of the old man Gem."
"So my initial fear was totally unnecessary?"
Hearing Shirou say this, Shinji's expression froze and he almost fainted.
"What on earth am I fighting so hard for?"
Shirou was unmoved: "Don't you have any idea why? To become stronger, to gain power, this is an impulse that everyone has. Although you always say that you have no ambition, you are actually quite strong-willed, especially in adversity. The second postgraduate entrance examination, the huge pressure and a group of newcomers to complete the project is the best manifestation - placing you in the Matou family also has this consideration. Facts have proved that the old bug has given you a lot of motivation. With the desire to become stronger, the rest can be easily solved."
"Then Justisa..."
"It's an opportunity arranged by the old man Gem. It's also an opportunity to visit the Shadow Kingdom to give Queen Scathach her spirit. Of course, the opportunity is given to you, and whether you can seize it depends on your own ability. If you seize it, you will take off. If you don't, you will live a stable life - we are not your babysitters, and we can't help you become a god."
"I understand." People need to help themselves before they can be helped by others. If you have given up on yourself, how can you expect others to help you
"In the end, you didn't disappoint us, and even set an almost unrealistic goal of defeating Queen Scathach and ending her eternity. Really..."
"Ahaha." Shinji scratched his head in embarrassment. "I was just too excited at that time. Besides, people should always have some dreams in life. Life without dreams is no different from salted fish."
"So, I decided to give you another chance, which is this trial."
