It's difficult to judge a novel that has these few chapters but here I go.
*Writing Quality: The English usage is perfect, completely unexpected from a newcomer, it's obvious it has a wide knowledge of the language; proper use of synonyms, great distribution of content between paragraphs, nice delivery of sentence, a little too many censored curses, I'd recommend change for words with less weight if you're going to use that many to denote personality.
*Stability of Updates: 10/10 since it's new.
*Story Development: Can't tell much about this except that the story is advancing steadily, there is an antagonist, a love interest? and power... a system as well; the book doesn't have anything particular that might attract you at first instance other than the 'eat' power which I believe will be dwelled upon in advanced chapters; still, it's a good start.
*Character Design: Not much to say here, one problem is that you have ingratiated so much the curses into the monologues, that's almost difficult to distinguish the characters from one another were you not to point it out; I recommend having monologues a little more original that give the characters a lot more meaning than the cliché young master and a young lady as for MC not much is said as to why he's trash why he as no powers, how he came to the sect, family, etc etc...
*World Background: Minimal background descriptions, such as place, geography, geology; architecture of places, scenery; so on and so forth, needs to be considered for each scene to give further impact to them.
The 'eat' power is something that might keep readers hooked for the first few chapters; consider adding something else to have them engaged, the cover is a 10/10 although it could be better, it's great to start.
Best Regards!
