Recommendations, I Want a Satisfying Read. Male- or Female-Oriented Is Fine, Variety Show Crossover or Quick Transmigration

I want to read something like Quick Transmigration: Romance Only Slows Down My Sword-Drawing. I'd like a more self-interested protagonist. Don't mindlessly bash the original female lead, and don't make the protagonist depend too much on some System. A villainous protagonist is fine.
