Jiang Chen traveled through time accidentally and began his journey in anime.

The world is tentatively determined to be: Naruto - Attack on Titan - Demon Slayer - Sword Art Online - Detective Conan, etc.

————

In the Naruto world, Jiang Chen obtained a system that gives him a 10,000-fold return on his disciples. As long as he teaches his disciples, he can get corresponding high-fold return rewards.

As a reward, Jiang Chen taught Hinata the black coffin of the ghost way that he brought from the world of death.

During the Chunin Exam,

Neji: "Give up, Hinata, you are not fit to be a ninja."

Hinata: "I don't want to run away anymore, Neji-nii, let's have a showdown! A faintly turbid emblem reveals an unruly and arrogant talent...Hadō no 90: Black Coffin!!!"

Everyone: "She calls me brother, but she kills me. This girl is so scary!"
