This is an era where gods actually exist. Yes, this is... Greece! The gods wield their power with impunity, regardless of gender, as long as they are good-looking. This is Greece! In short... you must survive! Greek Survival Rules: First, remember who's boss here? The gods. Second, remember, don't speak ill of the gods, they can hear you. Third, remember the previous point, the gods are incredibly petty and will really retaliate against you. Fourth, remember, don't mention gods when praising others (bottom line). Fifth, don't get involved with pretty women. Sixth, don't get involved with goddesses. Seventh, don't get involved with pretty things. Eighth, stay away from heroes, especially demigods! Ninth, keep your promises. Tenth, respect children, the elderly, and young people who talk to you on the street, because they might be gods. Eleven, return borrowed items. Twelve, don't be greedy. Thirteen, don't become a hero. The pure white hope will eventually be released in Pandora's Box, the Holy Grail War.

The six-year-old Shiro Weimiya has not yet started four battles and his parents are still alive.

very good! The next step is to stay away from the Four World Wars, refuse to be a partner of justice, rely on the grasp of the future direction, embrace huge wealth, and reach the pinnacle of life.

But–

Wipe out the evil of this world

Rescue the parallel world where Da Yuan is gradually disappearing

Smash the conspiracy of the Demon King

Save pan-human history

My path seems to be getting worse…

PS: Four battles → Garden of Avalon → Magic → FGO Five Wars → ? ? ?

I have a fiancée named Guye; I have a bunch of lolis at home, named Illya, Miyu, Chloe...

I also have a very large fan club named Type-Moon.

Life should have been very happy, after all, I have a house and a car, but - Guye: "Tianyang, the world will of XX world has sent a message, asking you to go there to solve the change."

Mashu: "Senior Tianyang, it's bad, Miss Nobunaga went to Honnoji to demolish the house!"

Holmes: "Master, I heard that Moriarty went to blow up the Reichenbach Falls, do you want me to stop him?"

Tianyang: "Oh my God! Can you guys just be quiet?"

After crossing over, I also turned into a slime named Rimuru… I thought I had crossed into the anime “Moe King”, but as a result, you actually told me that this is the world of “Xingyue”!

However… Rimuru immediately found out that it was not the “great sage” of the original “Meng Wang” that he acquired his unique skills, but a “great actor”!

Play the role of Enkidu in front of Ishtar and Jin Shining, the character is 100% compatible, and get the inherent Noble Phantasm: the wisdom of the people, the lock of the sky.

Play as the real person of Cihang in front of Shi Huangdi and Jing Ke, with a 100% character fit, and obtain the inherent skill: Immortal Body.

Playing Satan and confronting Jesus in Bethlehem, playing Zhao Yun and Lu Bu in the Three Kingdoms of Xingyue…

and many more……

Playing Guinevere in front of Arturia? Playing Saito Guidie in front of Oda Nobunaga? What’s happening here……

Am I not a man? !

…

So in a certain Holy Grail War, Rimuru, who came as a “Faker”, found that he had more and more acquaintances in the Holy Grail War circle, and he (she) looked at her as if something was wrong…

ps; there is a typo that may affect reading

In Rome, as a noble, I once engaged in verbal battles with the Senate! In Britain, I fought Germans alongside the Knight King! In the Tang Dynasty, I simply wiped out the aristocratic families and became emperor myself! In Greece, as a human, I danced with the gods on Mount Olympus! ...And now, in the Qin Dynasty, I serve as the Imperial Preceptor, assisting the First Emperor and ensuring the eternal reign of the Qin Dynasty. As a time traveler, I've reached the pinnacle! Unexpectedly, the Chaldeans accuse me of creating singularities and destroying human principles! Facing Gudako and the Chaldean Heroic Spirits, veteran time traveler Le Ang expresses his pity. "Listen, I never intended to destroy human principles!" The Chaldeans respond: "Do you think we'll believe your lies?!" PS: There are some secondary settings for plot reasons, so please don't get too hung up on them.

Tia transmigrated to Fuyuki City and became a red-haired boy. He originally thought he was just an ordinary person, but to his surprise, at the age of 7 during the Fourth Holy Grail War, he met Waver and learned that he actually had a magic circuit—and even accidentally awakened his Origin.

Tia never would have imagined that his Origin was actually sword! He turned out to be Shirou Emiya before the Great Fire of Fuyuki!

What shocked Tia even more was that his father and mother's Origins were Compassion and Return, respectively!

What the hell is going on here?! Is this really the Fourth Holy Grail War I know? This is way too absurd!

"Shocking! The French army surrendered to a young girl overnight!" "Shocking! The most popular person in Britain is actually her!" "Bizarre! A mummy emerged from the pyramid in the dead of night!" Lin Guan acquired a rather useless system, originally intending only to make videos to earn some pocket money. Unexpectedly, the characters he created began to appear in reality one by one. The Eternal King of Britain awakened. The French savior saint returned. The Egyptian Pharaoh, the Persian hero, the nine-tailed fox of a chaotic world—legendary figures appeared before people's eyes. (From the book [Azure Forest])

Waking up on the operating table. Durin had originally thought that saving humanity was all he needed. But then—Fuyuki's 'AI', BB-chan, who's trying to conquer the world, invades Chaldea, wanders the Far East, sharpening her knife to find the murderous woman I killed, and the Root Girl, who comes looking for Saber, is completely unreasonable—and then there's a silver-haired Leo woman who wants me to be her right-hand man and acting director of Chaldea. Hmm... This is probably a world where even messing around with Gudafu & Gudako won't be enough to survive!

I can't find the cover

End of the world.

The collapse completely came, and the only "human" in the vast land died at the hands of a breakthrough-level collapse beast.

His consciousness gradually faded away, and when he opened his eyes again, he saw only a grid of cells...
