looking for an mc who is op that is actually open about it... you have no idea how angry i've gotten from some shitty novels, where for some reason the dumbass author decides to force the MC to be very low-key, for literally no fucking reason. god it infuriates me. like for example The Luckiest Son-in-law or Abandoned Son-in-law. it's easier to find novels like this in the "son-in-law" genre where the mc's retarded mother-in-law bullies him for no reason, mc gets some sort of power, then decides to lay low because... he was previously weak so he shouldn't be allowed to have power? like what? so basically, looking for: any genre except novels where the main focus is romance op mc (can be a zero-to-hero type who grows into being op, but it can't take too long. this doesn't just mean regarding cultivation or martial ability. business, medical, etc is included) modern world only mc who is not a coward who hides his power for literally not a single reason except for forced plot also, it doesn't have to be action or cultivation novels, hell it can even be medical stuff like Great Doctor Ling Ran. stuff like business is fine, for example The Luckiest Son-in-law. note: it must be modern world, or something similar. no cultivation worlds as stated below, this includes worlds of magic, etc. cultivation is fine if it's in the modern world like Dragon Emperor, Martial God, but no cultivation worlds. ALSO, NO CULTIVATION NOVELS. Cultivation itself is fine, but not in cultivation worlds please. every novel with the characteristics i'm listing that is in a cultivation world, is 90% of the time a novel where endless arrogant young masters pop up, MC defeats them, arrogant young masters swear to get revenge, repeat for some reason, at least in my personal opinion, every cultivation novel can be categorized into an mc who lays low, or an mc who doesn't lay low but always goes up against young masters who he beats up, threatens, (for some reason rarely killing them despite them trying to kill him and his loved ones?) releases them, and then they come back to try and kill mc again, and this repeats countless times throughout the novel.
After analysing your requirements and deliberating with peers of same interest, I found that Invisible Dragon is the embodiment of what you are looking for.
If you don’t mind a future world(universe) then I recommend Star Rank Hunter. It definitely does not follow the common tropes, and the MC is very OP.
Try a novel from I eat tomatoes or Er Gen. These novels are almost free from arrogant young masters and other things that many people hate in CN. I know you dont like cultivation novels but those are worth a try. If you dont want too, you can try any of these: Returning from the Immortal World My Wife is a Beautiful CEO Forty Millenniums of Cultivation Raising a fox spirit at home I have a Mansion in the Post-apocalyptic World Epoch of Twilight
