Awesome action/mystery story recommendations

I'm a bit frustrated by romance and story that aren't that all too interesting. Is there maybe a webtoon with an interesting premise in your opinion and gets objectively better further down the line? I perfer action, but mystery and comedy are also welcomed. I want my mind be blown and laugh.

(Best not to include romance in anyway, passible are side characters with not much screen time)
(And maybe if you know a webtoon with gorgeous art but a meh at best story is also ok, since I'll just shut my brain off and slurp the art)
