When his father brought him back from the outer space, he was timid and afraid of talking to others. Now, he wants to play a game with his friend. He asks if the boy has been living in the city, and the boy says yes. He tells him that he thought he hated him, but now that he's grown up, he can talk to him. He gives the boy his dirty clothes and tells him to pick them up. The boy picks one of the dirty clothes, which is black, and tells the boy that if he likes it, he may keep it. When the boy picks up the black one, he says that he doesn't like the black very much, but if he does like it, then he can keep it, as long as it's not too dirty. He says that his name is li-cheng yumo, and that he hasn't heard from anyone since he fell off a tree. He's looking for a "dumb guy" who wants to kill him every time they meet. He wants to ask his father for a birthday present, and he says he'll give it to the boy. The two of them decide to spend their birthday together, and they decide to be emperors of heaven.
