In this chapter, we're introduced to a new character, a young tennis player named Zhengzhou Mingyu. Mingyu is a young man who has just started playing professional tennis. He's a good player, but he doesn't have a great deal of experience in the world of professional tennis, so he's still learning how to play the game. He tells us that his biggest weakness is his lack of intelligence, and that's why he can't play the world's best player like he used to. He says that he'll have to use his newfound intelligence against William, who's not very good at defending himself.
