Can someone tell me if this is a korean manhwa or a chinese manhua?

Korean

Idk but based on the authors list and the art, I would say chinese

nope it is Korean and trying to figure out nationality with artstyle is so meaningless, anyone can use any artstyle....

Yea yeah I know, it's just that I've seen this artstyle in chinese mangas only so far and when I saw the authors tag list i assumed it was chinese
