Douluo: I Don't Rely on the System

Who knows how sad it is at dawn and dusk. With a system on his body, who can know how sad he is? It's so cold at high places, and when he dances to clear his shadow, it doesn't feel like he's in the human world. (This book is a Douluo fanfic. If you don't like reading it, don't read it. This book is a bit biased toward invincible writing. If you don't like it, don't criticize it. The author is rubbish anyway… In fact, I don't know how to write this novel. (*^▽^*)
