I Am the Demon Lord of Fengyun Mountain

Don't ask me who I am, because you know who I am, the grave is half high. I once defeated the East Dragon Gate, the North Dragon Gate, the Five Sacred Mountains Temple and Fengtai Mountain with my own strength. I have three names, the first is "Lang Yan", the second is "Lang Si". This is the name given to me by people in the world, and the last one is "Before the sword is drawn, the man is destroyed"...
