The Revenge of a Serpent

He is a master of Duan family. How can he be willing to be manipulated as a pawn because he is naturally weak? Accidentally incarnated as a snake and reborn against the sky. I am not a mean person, but vengeance will be get. He who deceives me and defeats me will be punished even though he is far away! I was kind, but the world is complicated. If you insult me and bully me, you will be repaid ten times.
