The whole book essentially is "went to class and learned something, trained, ate lunch, went to class and learned something, trained, went to sleep" and then rinse repeat for days on end. It is basically a daily journal of the main character's time at the magic academy, and being a super dedicated student is just not very exciting. The magic system isn't revolutionary - just a typical cultivation system from xianxia stories - but it is coherent and makes sense. using "drug" instead of "dragged"), but on the whole the editing is to be commended.
A few minor typos, and some strange word choices that I suspect are a result of the author's dialect (e.g. The good: the grammar and formatting is quite good for a self-published novel. The story doesn't make any real effort to get away from the tropes of the genre, so if you're familiar with stories like this you can predict how the plot goes.

This isn't awful for a first effort from a new author, but there is significant room for improvement.
