Let's begin with the grammar. No mistakes so far other than the confusing dialogue phrases, sometimes they end up becoming too confusing to understand and sometimes I even mistake the speechs thinking they were thoughts. Well, for me the biggest problem of this novel is in its pacing and lack of description. The story is moving way too fast at least for me, and even now I still don't know how Hade exactly looks and even the MC doesn't escape this thing. Due to the lack of description, the only characters that actually marked me were the dragon and the swordsman, other than that I can't say much about the others. For the good points, I really liked how descriptive you were about the MC's feelings, the sensation, the process... They were superb and I could easily imagine myself onto the MC's shoes. I would just recommend you to change some things while focusing more on the world building.
