This chapter opens with a conversation between an uncle and his son. The uncle tells his son that the man who invented the "reactor formula" was his friend, and that if the man were to die, the formula would be in his possession. He tells the son that he should not seek out the man, because he is his friend and the man is more important to him than the man. He then tells the boy to call Little wang back and thank him for his help. The boy says that he would like to thank the uncle for giving him the "suluoer model." The uncle says that the model will be a birthday present for little wang.
