Everyone Transmigrates: There's Something Wrong with My Identity

The Tower of Myriad Heavens can connect to countless minor worlds. Citizens who turn eighteen are forced to enter it and randomly take the place of a native in one of those worlds. After spending a set amount of time there or completing a mission, they return to reality with their gains. As for those who get killed off... well...

Li Dayuan, who transmigrated here, discovers that these minor worlds are made up of the movies, TV shows, and novels he has seen. Isn't this his chance to take off?

But why does he always end up in the role of either an extra or a villain?

Could it be that he's really bad at answering questions?

Still, with his God-Tier Choice System, he says there's no problem.
