It's a rebirth genre of course all of them are similar as fuck.
(づ￣ ³￣)づWhat I'm trying to point out is that the author, for example, has used the word 'muggles' for people that can't use magic. That has been taken from Harry Potter.
Actually, that bothered me because I think it's the translators rather than the author. It's been a while since I've read any of the novel, so I may be wrong, but I didn't remember there being any jarring words like that (why would he immediately use "Muggle" if he's come from a completely different world?). I can't remember what he did say, though. Maybe just something like "mortals" (vs immortal cultivator) or something?
You can tell the author has taken elements from other films, manga etc. To make this because most of its not that original.
