Recommendation pls

One where the mc is op and he knows it but isn't evil or dumb. No harem just action, fantasy and adventure. I don't want no big boobies girls on my action manhwas ffs. Like no offense to girls with big boobs irl like I love yall and everything I just hate it when it's on manhwas cause 9 out of 10 chances they're dumb as fuck. And the flat girls are just an excuse to put loli but make them like older than mc. Anyways, adhd is shit again lol, pls recommend me a manhwas that's action fantasy and the mc is op but is kind and good. No harem but romance is fine aslong as the love interests isn't dumb and good for nothing. Oh and pls lots of chapters available only like 69+ and shit lol. That's all thanks in advanceeee!!!!!!
