when he duels his friend in chapter 18-19 it doesnt make much sense. hes level 25,000 or something compared to level 99 and we already have seen the stat difference even between 10 levels is a large amount. his stats are high enough at level 25,000 where he can just move and punch him 3 times before he is even aware what happened. the only logical explanation is hes letting his friend hit him? guess we will see in chapter 20
