Those Transmigrators from Back Then

The synopsis has been rewritten. Anyway, it's basically a story about someone who transmigrates through all kinds of worlds. At first, he's a warlock who has no intention of becoming a guide, but then he turns himself into a lunatic. Something like that!

P.S. The worlds he'll transmigrate to are from anime, games, and movies. If there's a world you'd like the protagonist to visit, feel free to suggest it.

Just don't ask for anything too over-the-top! Out-of-scale worlds like Dragon Ball and Doraemon are out!

P.S. I'm not Yiran Baozi. To reiterate, I'm not that Yiran Baozi who says he won't abandon a novel, then does just that.
