Decent overall. Interesting world building and enjoyable power system if you're more into wuxia. I thought the earlier levels were more fun.
Characters give me mixed feelings. Side characters are definitely bland and power creeped out of relevance very quickly, but antagonists have a bit more depth than one might expect. It's not much, but there's something there, which can't be said for many novels.
Very good. Great worldbuilding. Interesting characters. Well developed plot. One of the few novels with such length that can hold interest for over 3000 chapters.
