Review Detail of mightoguy in The Favored Son of Heaven

I just read the reviews and i found that many people are saying that mc is op or its a basic plot but i dont think as mc first is not op at all even the best they consider him to be genius and while he is training harder than others if u read it u will know who i am talking about. Also instead of basic plot its not like MC does not do wrong things and doesn't kill people . He does kill people while romance, his family and his own rules r pretty nice and he is not dumb
