To become Shirou Emiya, there are only three things to do.

First: high jump in the sunset;

Second: Transform into Emiya Giant Warrior and defeat the Holy Grail War in one day.

Third: "Be prepared to be stabbed at any time."

"But why? The system is here. You're telling me the Holy Grail War doesn't exist? There aren't even any magicians?!"

This is a resort where there is only daily life and no tragedy.

In order to protect this peaceful world, Shirou had to become the strongest worker, transform into a nuclear swordsman, travel to other parallel worlds to fight through the Holy Grail War and solve the burning of humanity.

I will write about twenty chapters of daily life in the beginning.

If you want to see exciting battles, you can jump directly to the end of chapters 19-20.

Tōsaka Tokiomi: This Holy Grail War is a sure win. I will reach the Root, and the Tōsaka family's century-old wish will be fulfilled in my hands! Weber: I'll prove myself in the Holy Grail War. Thirty years in the east, thirty years in the west. Don't underestimate the young and poor! Kenneth, who had just traveled through time: If I can... survive two years, I'll win... Director Ken, even after traveling through time, was still destined for death by the God of Fungi. Upon regaining consciousness, Kenneth was paralyzed. Looking at the glittering Command Seals on the back of his hand, Kenneth felt a pain in his Magic Circuits... No, I must live. Aozaki Touko's doll, give me yours! Rita Rogian's collection, give me yours! Lidel's inheritance, give me yours! The incomplete Third Method to construct the Holy Grail, give me all of them! And so, in Fuyuki City in 1994, standing beneath the shattered Holy Grail, gazing at the hole leading to the outside world above, Kenneth raised his middle finger to the sky. "With just a mere inhibition, I, Kenneth, will enter and exit the Root today!!!"

Reborn in the Sea of Life.

Ian, who was raised by Tiamat as his offspring, felt the extraordinary gravity.

Tiamat:

"It's dangerous outside."

"Especially girls."

"It's safest here in the Sea of Life."

Ian:

"Mother, the more you say that, the more I want to go out..."

"And--"

"I really can't drink the Sea of Life anymore."

After a long time.

Facing the numerous girlfriends from different eras around Ian.

Tiamat revealed his true form, circling and roaring in the sky.

"Kill all of you!"

"Take Ian away, bad woman!"

"He is my son!"

In a deserted alley, the two Ritas stared at each other in bewilderment. In the city sky, Wuxiang slashed the heavens with a single blow. In the wind of freedom, how could Wendy and I fly together? Why are St. Freya's dorms constantly being burglarized? Why did the dean collapse unconscious? Why did the white-haired father become a mother? How did heterosexuality become homosexuality? Who will become the king of the Honkai Harem?... Is this a distortion of human nature or a decline of morality? Everyone: Who did this? Hanabi: What? Hanabi knows nothing. Hehehe, I'm just happy.

[You are the Master of Chaldea, the savior of humanity. ]

[Your evil deeds are known to everyone from Orleans to Camelot. ]

[Every singularity has left traces of being ravaged by you. ] [Your fierce reputation can make servants tremble in fear, and can also stop the little demon pillars from crying at night. ]

[And you like to use this sentence to encourage your comrades the most——] In a certain singularity, Xia You's voice is serious:

"The singularity determines the survival of humanity. The only question is how determined we are to defeat it——My dear servants, have you decided who will self-destruct next?"

An Zhiyu traveled to the Land of Shadows, training day after day, year after year, with his master Scathach. In the evenings, after martial arts training, he would receive instruction in magic from Morgan le Fay. Initially, he and Morgan le Fay got along well, and he formed a favorable impression of her.

Then, one day, Morgan le Fay suddenly said, "In a week, the King's Choice will begin. My sister Artoria will extract the Sword from the Stone and become king... I need your help with something."

"What?" An Zhiyu asked.

"Before her, extract the Sword from the Stone, and marry her."

"???"

"The curse has been activated. From today on, you must find a way to marry Artoria!"

This was a world where timelines intertwined. He had extracted the Sword from the Stone, resolved the conflict between Scathach and her sister, and aided Gilgamesh. An Zhiyu thought he would continue his adventures like this.

Until one day, he was summoned by the Holy Grail.

Looking at the group of old acquaintances in front of him, An Zhiyu waved his hands awkwardly: "Hello..."

Artoria smiled and raised the holy spear in her hand:

"Shine in the End of the World!

[Day 1 of the time travel: Wearing Adi King's battle suit and dark red hair, is Emiya Shirou actually me?]

[Day 3: Confirmed, this isn't the UBW questline, no Red A experience packs, so I'll have to rely on myself to master Unlimited Bladework.]

[Day 20: Strengthened my magic proficiency and began practicing Projection. During this time, I met an alchemist who asked me where I got all these alchemical weapons made from recycled metal.]

What the hell is recycled metal?

[Day 90: Finally mastered my first Noble Phantasm, Projection. They exclaimed, "This is the Seven Kingdoms," an outstanding achievement in alchemy."]

Huh? I don't really understand you alchemists.

...

[Day xxx: Huh, I finally mastered Unlimited Bladework! Their expressions were fascinating, and they asked where the Nibelungen was.]

How come you don't even know about the inherent barrier? Isn't this... Type-Moon!?

As a master who traveled through time, lan was not so familiar with Chaldea. But it didn't matter, he had a special ability that other masters didn't have - that was the

simulator.

This allowed him to leave his own footprints in history.

-Although it was not normal.

[You became the husband of the demon concubine, but at the same time you cheated on the Holy Knight King disguised as a man, and Britain was in a mess because of you. ] [You controlled Tamamonomae, and as a master, you let Minamoto no Raikou witness what physical demon exorcism was. The ghosts of the Heian era avoided you. ] [You made Medusa lose her mind, and the whole of Greece echoed her saying that she would take off her blindfold when she met you again. ] [You are Jeanne's soul mate, and only you know how to make this saint who is usually

very restrained achieve liberation and relaxation in various senses. ] lan had to say that this simulator that understands people's hearts is really suitable for

him.

Solve all problems in his favorite way.

Everything looks good.

Until the moment they came to him.

When the war ended and the cure for oripathy was discovered, Su Xia, a Rhodes Island doctor, retired from Rhodes Island and retired to Lungmen with his girlfriend, Miu Miu. Unexpectedly, his departure sparked a peculiar outburst among the Operators. Lin Yuxia, dressed in a black and purple dress, knocked on his door at night. "Doctor, you don't want the news of you and your wife's seclusion to be exposed, do you?" Shi Huaiya, the heir to the family business, arrived in a luxury car. "Doctor, you don't want to see your wife's eco-park fail, do you?" W produced a thick stack of intimate photos of herself, Theresa, and the Doctor. "Doctor, you don't want your wife to see these photos, do you?" Ghost Shark, dressed in a nun's uniform, gently shook a letter from Skadi. "Doctor, you don't want to see the swarm get out of control, do you?" "Doctor, you actually like it, don't you?" "..." For the sake of his and Miu Miu's peaceful married life, Su Xia found that sometimes he had to compromise with them. And some things only have zero times and countless times...

(The author wrote this for fun. It was inspired by a rage after eating a stone in other pre-Civilization fanfiction. And although this book is a pre-Civilization fanfiction, there is no yuri, no yuri, no yuri. The author himself hates yuri!)

A paranoid and arrogant time traveler, guided by a higher-dimensional will (the author), embarks on a journey to save the world in order to return home. He hates the tone of this world and everything in it, and scoffs at the idea that love can save everything. However, in order to return home and save the world, he is willing to give everything he has.

Maybe it's a multi-heroine romance? Probably. I wrote it with a magic tool, so don't expect it to be too logical.
