My Game of Destiny: I Know All the Anime Worlds

Two centuries of terror: the Game of Destiny devours humanity, claiming 70% of the population. Even the national hero is dead, and the blame falls on me, Tong Gu—the so-called \"Cheater.\" Tomorrow, I enter this death game. But they don't know my secret: every deadly \"Game of Destiny\" world is a familiar anime, manga, or game from my past life! I've spent years preparing, hoarding genetic enhancements, and meticulously mapping every plot point. I'm not a fraud; I'm a player who knows the script. My plan was to start in One Piece for easy power, but a last-minute betrayal shoves me into the blood-soaked world of Demon Slayer. The first demon I face? It thought I was prey. It learned I was a monster.
