Cultivation from the Naruto World

Born into an ordinary family in the world of Naruto, Bai Sui has no kekkei genkai, no system, and not even any inherited knowledge of the ninja arts. To avoid becoming collateral damage in the Otsutsuki clan's future infighting-just another statistic used to demonstrate their power-he has no choice but to draw on the memories and knowledge in his mind to make himself and those around him as strong as possible. All he wants is to survive in this twisted world.

P.S. Beyond the Naruto world, I've currently selected the following settings based on your comments: One Piece, Demon Slayer: Kimetsu no Yaiba, Jackie Chan Adventures, the Primordial World, and (Harry Potter, Fate, The Mummy, Transformers, The Wandering Earth, several Call of Cthulhu scenarios...). The settings in parentheses will be combined into a single crossover world. This lineup is tentative, so if there's a world you'd like to see, leave a comment. If it's a good fit, I'll add it.
