Dr. Liu is an average guy who broke my arm. He's a good fighter, but he doesn't know how to control insects. Mr. Liu wants to know what's up. He tells his mom that she's finally back in the city and that they're looking for her. He says that he heard that she sold them a green onion and that he's got a good sense of humor. Mrs. Liu tells him to stop pretending. She tells him that if he refuses to tell them the truth, they'll be rude to him. If he refuses, she says, he'll kill him. She says she'll let her son go once he shows her his secret technique. She asks him if he thinks he knows how to fight and he says he does. He asks if she thinks he can kill her son now, and she says he can, but she won't stop until he tells her the right way to do it. She wants to kill him, too.
