Repay the Favor? Can I Teach You Step by Step?

When I came out of seclusion, I found out that my benefactor had turned into a little bean curd. He was hacked to the point of losing his consciousness because he helped me transform. For a small problem, I will demote you and become your mother. The ancients said that I can't repay the kindness of saving my life. I should give you my life. You are not here to repay the kindness. You are here to avenge me. After I become successful, I have never married a wife and had children. I have never seen a beautiful woman or a luxury car.
