I Ended Up in the World of Murim

Did you not wish to see me, My Lord? I've taken over a man's body in the world of Murim, and to make things even more complicated, it's the body of an extra in a world where everything is determined by strength and skills. There's only one way to survive and make it out of this place. Women? Power? I will take everything away from the original protagonist and rewrite the novel!
