It's bl where mc transmigrates to different worlds and has system to help him conquer the male leads. It's kinda like "Cheating Men Must Die" if you've read that one. I can't remember much of the plot but there were some arcs where he's in murim as a young lord and some kind of "female" in a primitive world.
