Ding! As the only descendant of the Uchiha clan on the continent of Teyvat, it is your unshirkable responsibility to revitalize the clan. Complete the quest by doing any of the following.

A. Economic revitalization: Become the richest man in Teyvat;

B. Strength revitalization: become the strongest force in Teyvat;

C. Political revitalization: unify the seven kingdoms of Teyvat;

D. Revitalization of Offspring: Within ten years, have ten children of Uchiha bloodline in Teyvat.

Uchiha Mijo stared at these four incredibly difficult options, struggling over and over again, and then asked weakly: "Can I choose D?" (This is a newbie's early self-entertainment, so there are many problems and the progress is slow. If you don't mind, you can skip to Chapter 48.)

Shirou: Huh? Messenger of Justice? What's that? If you love your sister, go fight in the Holy Grail War. If you can't even kill six people in a row, and you can't even take down an EA, what's the point of being a sister-con? I always take it with my face, understand? Excuse me, young man next door, but you actually need Saber to help you fight in the Holy Grail War? I always tear people apart with my bare hands, okay? You can't even tear a Servant apart with your bare hands, and you're still calling yourself Gudako's dad? Have some shame! Today, I'm going to teach you how to fight the Holy Grail War! ...

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.

Bai Ming, 20, is a time traveler from China, having journeyed to the Type-Moon world. A member of Chaldea's A-Team, he beats up werewolves, slaps lovers, argues with gloomy, withdrawn girls, intimidates schoolgirls, and knocks out insomniacs. He owns a simulator system and fears the world isn't violent enough.

"I traveled to Type-Moon and gained the recognition of the Root. As long as I can die an abnormal death, I can ascend to the Throne of Heroes and become the Lord of the Throne of Heroes, an existence that is stronger and freer than the Seven Crowns." "For this reason, I started to act like a fool in Type-Moon." "I scolded Gilgamesh to his face, challenged the almighty Zeus in Greece, openly kidnapped Skadi in Northern Europe, declared that Solomon was a demon god instead of the Son of God in Israel, and stood on Morgan's side in Britain..." "But why am I still alive now?" 1994, Fuyuki. A famous figure in history, the third friend of the Most Ancient King, the first prime minister of Mesopotamia, the man favored by the Greek gods, the king of giants in Northern Europe, the incarnation of God who awakened Solomon's humanity in Israel, assisted by Prince Camelot... The young but weathered-looking Lovi sat on the top of the Fuyuki Bridge, sighed, and looked at the scene in front of him: "Tell me, what went wrong here?" "Or, you kill me and let me ascend to the Throne of Heroes? Please!" Kiritsugu Emiya lit a cigarette, glanced at Artoria who was holding the Holy Spear next to him, the King's Treasure unfolded by Gilgamesh, the red spear tip extended from the Kingdom of Shadows... The hand holding the cigarette trembled slightly.

Su Ming, who stayed up late playing games, accidentally traveled to the continent of Teyvat and was trapped in a strange secret realm for ten years.

Since he was already here, he might as well make the best of it. After leaving the secret realm, Su Ming decided to have a good time in this world.

Hehe, Eula’s wife, Amber’s little angel, Jean with long hips, Klee’s girl, I’m coming to Mondstadt.

While traveling through the seven kingdoms, Su Ming gradually discovered the secrets of the entire world and was inevitably drawn into their respective troubles...

System + Yingmei + Multiple Heroines + Daily Life + Make Up for Regrets + Reject Knife

(No protagonist + secondary creation as the main part) The viewing screen suddenly came into everyone's sight. Before people could react, the secondary creation video that followed made everyone feel socially dead in different worlds.

Artoria: Arthur, my proud son, the glory of all Britain. As the Crown Prince of Camelot, you shall inherit all that I have: my throne, all my possessions, including but not limited to the Knights of the Round Table, my Holy Lance and Sword, the noble steeds of the Royal Stables, and all the treasures in the treasury.

Mordred: Mom, what about me? Ah, I see. My brother inherits everything from you, and I inherit everything from him. That's the happy end, right? So, when will you abdicate, Mom? How many tables will we have at the wedding? Can I use your scabbard as a surfboard?

Altria: Knight Mordred, I appoint you Earl of Glamorgan, and you must take up the post immediately!

Traveling to Arthurian Britain, Artorius faces only one question: a major traitor or a minor villain?

[Detective + FGO + Slice-of-Life; basically an otaku-style novel; beloved trope of Heroic Spirits falling in love; NOT a harem; Warning: MC’s presence is relatively low — if that bothers you, turn back!! Some Heroic Spirits’ genders follow historical records, and there will be CP pairings, e.g., Old Saber x Eriri, Oda Nobunaga x Miku Nakano. Personalities of Heroic Spirits are kept intact. If you can’t accept that, just… don’t read!]

Transmigrating into a world that’s a crossover of slice-of-life anime and Detective Conan, Aoki Makoto, with no knowledge of the plot, thought his life would be simple: rely on his phone from his past life, stay far away from trouble, focus on making money, and spend a rich but boring life.

Little did he expect that his real cheat would arrive… sixteen years late!

System: “Become a Master and save the world!”

Aoki Makoto: “Do I get a girlfriend?”

System: “…Huh?”

Aoki Makoto: “Why am I not interested in all those anime heroines? Because my ideal type is Gudako!”

System: “…Fine. If you succeed, I can help introduce you. But first, I have some bad news.”

Aoki Makoto: “In front of Gudako, nothing is a problem.”

System: “The detailed personality data of the Heroic Spirits has been lost, so you’ll have to play them yourself. In other words… have you read any ‘vest novels’*?”

Aoki Makoto: “…No problem, no problem. Oh, by the way, does your introduction come with a marriage guarantee?”

And so begins the story of wearing the “vest” of Heroic Spirits to save the world… while also, incidentally, falling in love.
