Cringe garbage
Guy wants to become best in the world for no reason and then becomes the best in the world for no reason. In the process he creates an army of sicophant women that follow him around and do his bidding, but he has 0 sex drive so he doesn't think about it in a harem way.
The MC simply does not make sense. He is not human. His motivations, progression in power and character growth, all of it is either SKIPPED completely or it simply does not make sense. Why does he want to be the best? Why does he need the army of females? No clue. His motives are beyond mortals to understand.
