I'm Shenji, what are you doing?

"The Land of Steel".

An extremely heavy name.

A world in which living things cannot survive, the name of the current world.

It is not a formal name, but a common name commonly used among "people" living on the desolate land. It is used to refer to the dying star, the earth that is about to die, and the end of the century.

As the name of the Steel Land indicates, most of the continent is now a cracked wilderness, covered by gray and white clouds. Food cannot be grown, and the atmosphere is no longer as hospitable to animals as it once was.

Yes, this is the distant future, the end of the earth.

In a sense, the planet is also a kind of life. Although it is extremely long compared with the short-lived human beings, it will eventually die.

The earth is dying, and "Gaia" as a restraining force is also disappearing. Before disappearing, it called its compatriots, the U.O.s from other planets in the solar system, to exterminate all life on the planet.

U.O, the abbreviation of Ultimate ONE, is the strongest life species on each planet. Each has the terrifying ability to wipe out all life species in the existing world by itself. The concept itself has no name, it is the name given by the remaining humans, just like "The Land of Steel".

That's right, even if the planet ends, the human species cannot be wiped out. They still rely on advanced civilization and technology to survive. This also means that the long-term balance and struggle between the two major restraining forces "Gaia" and "Alaya" has finally come to an end, and "Alaya" has won the final victory.

However, the price is extremely heavy. Needless to say, the home planet died, and the ecological environment was completely changed. Human civilization was also severely damaged. It was dying on the ruined land, struggling to survive, and living under the threat of U.O. every day.

There is no doubt that this is an extremely bad ending.

Moreover, it is the ending that all parallel worlds are bound to usher in - "The Gem Man", "Night of Varzia" and other powerful figures have foreseen this ending.

"Night of Varzia" kept making calculations to avoid this ending, and tried every means but could not get the answer. Finally, he placed his hope in the legendary "Sixth Magic" and became a vampire.

The same goes for "Jewel Man". In his opinion, although he did not find a way to avoid it, the ending could definitely be avoided. The reason is simple. The earth is not the oldest among the nine planets in the solar system (it is currently 1999, and Pluto has not yet been expelled), so it is obviously not a natural death. Since it is not a natural death, there is a possibility of avoidance.

To this end, he used the second magic "Parallel World Interference" to constantly travel across world lines and conduct various experiments. Countless failures, countless summaries, and countless restarts, the accumulated data and experimental reports can fill an entire library.

The traveler with the pseudonym Shirou is a friend he met while traveling continuously. The traveler now named Shinji Matou is also one of his experimental subjects, and he is a very special one.

"Because you and I come from the same place?"

After listening to Shirou's narration, Shinji was thoughtful.

"This is just a part of it. To be specific, it is outside the Xingyue universe and within the concept of the earth. The former makes you an unpredictable variable - with variables, the ending can be changed, whether it is good or bad, the most fearful thing It just remains unchanged. The latter ensures that you can smoothly integrate into the earth and will not be rejected because of being 'foreign'. You don't need to delve into the specific principles for the time being, after all, I have only understood the tip of the iceberg of the multiverse."

"I understand, don't touch things at that level if you can't reach that level - you just need to tell me what I should know."

This answer made Shirou very satisfied.

"With this attitude, I feel relieved. It's not in vain that the old man threw you into that special world line."

"Special world line? For example, Justeza's survival?"

"This is just one of the special features. In addition, there are many special factors that are combined. For example, Death Apostles and Servants. Dead Apostles are the enemies of human ethics, and heroic spirits are the defenders of human ethics. The two are in opposition to each other. Therefore. , in a world line where the 'Summoning of Servants' system is spread, the power of the Dead Apostles will become weaker. In the world line of "Fate Zero", the power of the Dead Apostles is far less than that of the world line of "Tsukihime", twenty-seven The list of ancestors is also different. The most important thing is that Roya, the origin of the story of "Tsukihime", was also destroyed by Edmond Dantes during his lifetime."

"Huh? Is there such a setting?" Shenji was stunned, "Then if I asked Aozaki Orange to go to Tono's house to find Roja, wouldn't it be a waste of time?"

"Didn't I say it? The world line you are in is special. It is a flask, and various elements that Old Man Gem and I can add are added to it. Whether it is "Tsukihime" or the Fate series, they are all elements One, so Roja still exists.”

"That's it..."

"By the way, there is one thing I want to remind you - although it has successfully combined various elements, it is not the original world line after all, and with you as a variable, I don't know what changes will happen in the future."

"Don't you have the right to use Mooncell? How could you not know?"

"I haven't observed that world line since it was formed. After all, it is a man-made world line and is not as stable as an ordinary world line. Even if I just observe a super large variable like mine, it may have a bad impact."

"Is there no problem with this world line?"

"No problem, because it is a normally derived world line." Shirou sighed helplessly, "But now more than 70% of my body is composed of alien ingredients. In an exclusive earth like the Moon World, I As soon as his true form appears, he will be jointly attacked by the two major restraining forces, and in the end he can only enter the earth in this way."

"Doesn't it sound like a good way?" Shenji said thoughtfully.

"Of course, it's not that easy to replace the existence of a Servant. That is a heroic spirit that has a name in human history. Even Mooncell's power is difficult to interfere. First of all, it must be compatible, and secondly, it must be willing to cooperate."

"Voluntary?" Shinji looked surprised. Amakusa Shirou Tokisada was so determined that he was willing to be replaced. "How did you do it?"

Shirou chuckled, like a weasel who succeeded in eating chicken: "I showed him "Fate apocrypha" - the adapted version. Then I told him that there is restraint, you can't succeed, but there is a slight possibility if it were me." "

"You are cruel!" Shen Er was convinced, completely convinced.

Amakusa will do anything to save humanity, including her own life. He chose Semiramis as his servant and was prepared to be made into a puppet by her. When he knows that his wish cannot come true, it is not difficult to guess what choice he will make.

"But even if he gave up his existence, his obsession remained in the spiritual base. He always reminded me to seize the Great Holy Grail and save mankind. Especially after I hid from the Great Holy Grail, that obsession almost made me noisy. I can't rest for a moment, so I had to make that wish. He is worthy of being a saint who has endured for sixty years. For this reason, I give him a toast!"

"Honor Amakusa Shiro Tokisada!"

Regardless of whether his wish is correct or not, his persistence and dedication are worthy of respect.

PS: U.O is the real top combat force in the solar system. The residents on the third level of the pyramid are truly invincible. As for how strong it is, it will be described later.

PS2: The current trend is that the reason why the earth dies first is because of humans.

PS3: In the world of "Magical Girl Illya", Ainsworth may also be a pawn of the old man Gem.
