I like the novel wher the mc is the shou but op like: I Was Once a Legend And of course the sweet ML :3 i don't mind the setting whether it is interstellar modern ancient etc. As long as it's good novel But i'm not really like ABO world so you could exclude it Ah but also too much drama isn't my thing.. usually this kind of plot is the most common one And i don't really prefer QT it's better like the novel I mentioned wher they go to 'box' to complete stories rather than QT Oh it's better if the mc has some kind of dark past which is leave a shadow on his mind :3 cuz it's nice to know when he is op af but there's still a time where he is vulnerable hahaha..

The Earth is Online Game Loading card room the shou are strong and independent in these novels puzzle solving in multiple room like stuff Game Loading is in this list for some reason I don't remember
I recommend The Founder of Diabolism. The mc is the shou and basically everyone in the book except for the ml is at least somewhat afraid of him. He's got a really dark past where some terrible things happened to him and he also committed some sins, which is slowly revealed when the plot progresses. The book is heavily based on cultivation, ghosts and exorcism, but there's also some mystery involved. You said you don't like drama, so you might not like this book since it can be quite heartwrenching, however I can assure you, there's no dogblood or things like that. All the drama focuses on his dark past and the mystery they are solving.
Well, can't help it in that case. Another book I could recommend is One Useless Rebirth, though it's not the protaginst but the ml with the dark past. It's got way less drama.
