Story is just very slow and drawn out. If your selling a book as a cultivation book, you dont have to spend 3-4 chapters explaining what it is and how it works. The characters are very childish and immature in a very serious and mature setting. The clash just feel strange and makes everything hard to follow.
Really what killed it for me is all the exposition and no hook. I kept waiting for something to appear, whispers of a dark evil or something but the writer was to interested in explaining what cultivation is.
