Horrible, misunderstandings and conflicts that can be solved with just a sentence or a call is stretched out to 3-6 chapters.
MC says that he's realized the importance of power, yet he doesn't actively do something to acquire it even though he has a cheat that can insta-learn everything with just a glance(in some ways it's more OP than LOHP). He doesn't surf the web for useful manuals i.e programming, other language, martial arts..etc. those things he can master in just 10 minutes but he doesn't seem to want them.
MC hesitates to join an organization that equals the military even though he says power is important.
People annoys him and wants to/tries to kill him yet he just leaves them with either a swollen face or at worst a broken arms or legs.
He says he doesn't want the limelight and doesn't want to show off, but his actions are everything but.
Spolier:
A perverted martial instructor was assigned to their class and was very unreasonable, feeling the girls and beating the guys with the slightest bit of disagreement. MC could have this instructor replaced and punished with just a call cuz he's a benefactor of someone higher in the organization but nooooo.
MC decided to challenge him to a duel, even though he doesn't want the limelight, doesn't want to show off. After he beat the instructor, comes the instructor's older brother, MC still decided to beat the guy even though he doesn't want the LIMELIGHT.
With his cheat the book could be more interesting, but the author wants his story to be about everything overused and wants nothing to do with originality.
Tl;dr
Op cheat, dumb mc, hypocrite mc, negative IQ villains, typical wuxia, overused tropes.
