There seems to be a lot of copy/paste novels like these: It Turns Out I am a Dao Ancestor, I Turned Out To Be a Peerless Expert, where transmigrated MC gets a system that raises his non-combat skills to the top but he cannot cultivate. In all of them those non-combat skills are actually quite combat ones and extremely OP, but MC don't know this and author makes sure it stays this way. So I'm curious is there a similar novel but without that misunderstanding of MC about his skills or where he figures out their power quickly enough?
Just started this one but it sounds close enough so far: Disciple, don't cause trouble, master won't leave the mountain.
So you are NOT looking for: MC never realizes he is strong MC knows he is strong MC goes from weak to strong You ARE looking for: MC was strong from the beginning but underestimated himself, but he quickly realizes he is strong I don't know how fast you mean by 'quickly', but the MC in Never Die Extra fools himself into thinking he is weak before finally admitting he is strong about 150-200 chapters in. If I'm wrong about what you're looking for, then is it any different from a regular weak-to-strong MC?
Why do basically none of these show up searching them on this site? Peerless expert, and the mountain one I tried to lookup and can't find here.
Ode to Gallantry The story is about a boy who never gets a proper education in even the basics of society; no literacy, no proper training in martial arts, no understanding of etiquette, not even basic human interaction. So we get to see everything that he learns as he experiences it. And as he doesn't get any proper martial arts training, he fully understands that his actual fighting skills are poor. What he doesn't know though is that his inner strength is at an absurd level and this lets him overcome a ton of encounters that he'd otherwise lose. And so there are two layers o misunderstanding here: the protagonist's opponents and observers will underestimate him when they first meet, they tend to overestimate him after a fight, and he himself always underestimates his own abilities. Don't trust the tags on NU. They're user generated and they're often incomplete. Except that she always knows exactly how strong she is compared to her enemies. And whenever she learns new skills she'll experiment with them and with combos so she can always get the most out of them. In many ways, Kumo is the opposite of this topic in that she works harder to fully understand her powers than any other protagonist out there.
