It could easily be either the same artist or a different one. Drawing a long ongoing series gives plenty of time to change your art style as you go, but some of the Chinese comic publishers also just change out the artists for whatever reason. The problem is that a number of series are poorly documented when this happens, so it might only end up with the one artist's name or using writer's name for both even when that person wasn't actually the artist. Personally I don't care enough to go digging around through Chinese websites to try and find out. I'm not exactly reading stuff like this on here because I'm well versed in the native languages of all the stuff on here, after all.I'm re-reading this, and compared to the latest chapter the art style is really different now?? Are there different artists for this? Or is it all drawn by a single person? Because I'd have to say, I like the art for this first arc the most, but the recent ones are kind of weirder looking? No offense but I'm just genuinely confused :/
