[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!

Perhaps it was the Star God's interest that led to the injection of chaotic fragments of memory from a higher dimension into the bewildered consciousness of "Star." The result was that this already despicable pioneer, with the addition of an inner monologue, became even more despicable. Star, who had committed countless evil deeds, stole the Black Tower doll, tried to matchmake Seele and Duck, and even wanted to be Duck's stepmother. She petted Tingyun's tail in the Immortal Ship, reenacted the Immortal Ship past with Xiao Guizi, and finally, her filial piety turned into a corrupting influence on Kafka. She even went to Teyvat, where she met Yingmei and went around flirting with girls and causing trouble—disrupting the Rock King's retirement plan, colluding with the fox woman to break Shadow Dao's heart and stop pursuing eternity, then abducting Nashida in Sumeru, and going to Fontaine to harass Frinina. But everything has a price. When countless girls who had been deceived stormed into the Dust Song Pot to confront Star and question her about why she was so despicable, Star could still stand tall with her hands on her hips and say righteously: I am just fighting for all the good things in the world! To make this world the way I envision it… Wait, what's that medicine in your hands? Herb resistance potion? Wait… wait a minute! Can we make peace? So many people… No, no way! -- Primarily set in the Iron Plains, with possible inclusion of other ACG worlds in the mid-to-late game.

Rhodes transmigrated to Beloberg, encountered a monster from a different world, and couldn't defeat it despite his best efforts. However, he transmigrated to countless worlds where soul fragments appeared, sharing his memories and power. But their art style seems a tiny bit off... Muzan Kibutsuji: Noble families never fight alone. Yoriichi Tsugikuni, go ahead and talk to my army of 100,000 demons! Esdeath: Forward, conquer, I will finally unify the world! Sirin: This is the complete Herrscher, the complete Sirin, the complete me! Talulah: In the name of the Red Dragon, Victoria, I will return like lightning! Morgan le Fay: Kings are never chosen by heaven. Foolish sister, return to my golden cage, sing my praises! Rin Tohsaka: Farewell, Father, and my cowardice. This is the time to ascend to godhood! ...Alright, alright, everyone seems to be quite troublesome. It seems I have to come out of seclusion and enjoy the company of the demoness. Eh, wait, you guys... Waaah!

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.

Luo Ning transmigrated to the world of Collapse Iron and unexpectedly obtained the Underworld Conquest System, but instead found himself being conquered by various older women using their Underworld abilities! Task 1: Kiss March 7th. But why did March 7th use the "Pear God Throw" and a hypnosis app to force a kiss on him?! Task 2: Have a semi-deep conversation with Himeko. Himeko: Want to join the Starry Sky Train? That depends on your performance. Task 3: Get Natasha to treat his swollen wound. What the hell? The dignified leader of Earth Fire, the life-saving Natasha, actually used an Underworld potion on him?! Seeing the increasingly outrageous tasks given by the system, Luo Ning initially wanted to conquer the older women himself, but discovered that they all seemed to have ulterior motives towards him! ... Himeko: Luo Ning, I don't want to teach you one last lesson; I want to keep teaching you. Bronya: From now on, you are the true Great Guardian. Clara: Brother Luoning, I can't stand up anymore, let my Shiva's clone come and help me~ Tingyun: My benefactor is really in a hurry~ I almost exhausted myself. Liuying: What?

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...

Finding Kiana and Bronya during my travels should have been a happy thing, but, Your Excellency, what's wrong with you?

The captain was dumbfounded when he saw the blonde girl in front of him.

Kiana and Bronya also seem off.

One day, the captain in the basement regretted his actions, saying, "I was so stupid. What kind of girl is so overly familiar, and only with you? Besides, Kiana even has a love interest in the story."

(A desperate attempt to win back her husband? + Restart, I'm the protagonist + Too many elements)

(There are quite a few out-of-character (OOC) elements, so remember not to use your brain while reading.)

System, a high-end, classy term, the golden thigh of the golden fingers. A mass-producer of cheats. Just as Li Zihan was overjoyed to discover he had a system, he received a message from the system. This system is about to shut down due to insufficient energy. Please work hard to gather enough energy and restart the system as soon as possible.

(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.
