It's the middle of the day, and Madame Mang-Tian is trying to teach her son how to make a machine. She's worried that he's too young, and she doesn't want him to try. She tells him to hit a piece of metal with his left hand, and he should use his right hand to do the same. He's not strong enough to finish the task, so he'll have to come back the next day. He tells her to stop patting him on the back, and to apply some medical cream to his red and swollen hand. He says that he passed the test, and that he plans to save money by buying "spirit souls" .
