Due to my lack of experience with the Cultivation genre beyond that one Worm fanfic I read months ago, I really have no right to criticize about the mary sue-ish nature of the characters. Σ(´∀`;). What I can say however is that the grammar could use some work. Some sentences feel incomplete, missing a word here and there. There's also some inconsistencies with the tenses being used in the same paragraph. The world is fairly detailed, and I can see the story going far with a bit more polish. Keep on keeping on ?
