Guys what novel is Spirit Blade Mountain based on if it's based on a one because it feels like it is but I'm not sure which one, also I'm a lazy fuck who can't google and want to make a thread =D Ps: pssst pssssstt wanna know something funny kids? I actually wrote Spirit Balde Mountain when typing the title but noticed and changed it, yay.

It's not really all that different from the webtoon to be honest. I've read both to the most recent chapter and can only see a few minor differences between the two.
