Ten Miles Sword God
I really want to enjoy this but it really gets frustrating. He is (or more rather was) a celestial lord (possibly most powerful) cultivator back in the other world. Even now at his weakest, he is still much stronger than any human (except certain martial artists for now). Why is he humbling himself so much, talking about his poor grades, working at a bar, talking about how he needs to work to survive, and worrying about his class mates looking down on him when he is a 500+ yr old powerhouse. These gaping plot and personality holes really get annoying.
