Is this korean or Chinese?

Korean you can tell by the text on the cover if your familiar with the language.

But the more you read and look at the bottom of each chapter the authors/editors/artists/translators you have people writing in Chinese, Japanese, and Korean

Hope that helps

Here in the cover it's in korean but then on the chapters it's in chinese that's why I got confused, so I guess the translator used the chinese ver

Nevermind I reached chap 6 and it was explained(≧∀≦) still thanks
