Miss Gao tells the gang about the mole on her eye. The mole is one of her clients, who is responsible for the death of her daughter. He even threatened her with her death, and she even wanted him to marry her. Gao says that he is only alive because he is lucky. He says that because of his talent, he has been regarded as an obstacle to be eliminated. He guesses that she has avoided the other person's name because she has been afraid of losing her job. He also guesses that the mole is the one who got pregnant. He asks Gao if he knows about a private club, called "Dengxian," where the mother and daughter had kidnapped him. The club has a membership card with the three-digit code.
