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!"

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.

(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.

"Down! Too down!" It was clearly meant to be a down simulation, but the system, looking at the man before it, couldn't help but fall into deep thought. Seele and Bronya, Silver Wolf, Shenhe and Kafka, even to round up allotropes, they'd added Little Grass God, Bailu, and Yae Shenzi... Luo Ran hugged them and said, "The life simulations in the down simulator are fake." "The down simulation, the richer the rewards." "NPCs in the down simulation won't resist." "Then this isn't a buffet!" "By the way, what other attractive female characters are there? I can't wait!" "They're just NPCs! Get a grip!"

Why does Ryunosuke Yusheng commit suicide frequently?

Why did Tohsaka Tokiomi hunt down his disciple?

Why doesn’t Jin glitter cooperate with the emperor?

Why is my king homeless?

Behind all this, is the distortion of human nature or the loss of morality.

Please read this book, a man who plays tricks by comics.

In the two-dimensional world, Wang Chong, who is charged with the villain system,

stands on the rooftop and says with great emotion: "Actually, I want to be a good person."

System: "Stop it, Chong, there are all your creditors outside."

Irisviel: You polluted the Holy Grail and turned me into your shape with your own hands. Where are you going to escape now?

Toosaka Aoi: I have already lost my ex-husband, I can't lose you again.

Saber: Woo! All this is to protect Mrs. Elly, come at me! You bastard!

...

Various female characters appear together to ask for the debt of love committed by Wang Chong, and surround Wang Chong!

Wang Chong forced a smile and said: "Hey, can we reconcile?"

The universal wishing machine - the Holy Grail. Surrounding the Holy Grail, those who carry hatred, those who stick to their ideals, those who have dreams, and those who have missions, struggle in front of this "miracle".

Huo Yuhao: "Disrespectful people, disappear under the glory of the Pharaoh!"

Tang Ya: "The soul is weak, and the machine rises!"

Orange: "Go! Fight! And then win!"

The "Master" of another world and the "Heroic Spirit" of human history "See the roar of this monster!" "Come! Come and enjoy this forbidden feast!" "Go to hell! Damn God!"

And behind this, what is hidden is - "Hehe... Hahahaha, it's really pleasing!"

Xia Qing, who came to the Fourth Holy Grail War [Fuyuki City], opened the theocratic system, and obtained the substitute [Platinum Star], and began his journey to the realm of God.

In the collision between the heroic spirit and the substitute, who is better?

Why was Mr. Jin who was passing by so frequently beaten?

How cowardly did Oniwu Tsuji Muzan become?

Sister Pao's safety pants mysteriously disappeared, who did it?

An unscrupulous brave man actually brought a young raccoon girl and drove her around wantonly. Is this a loss of morality or a distortion of human nature?

What is the true purpose of the blue ribbon? The truth that makes the washboards angry is actually...
