It's late, and Lady wu yang still hasn't woken up. Young Master weiyang asks if she's going to study the poisoning, and she says she isn't going to. He tells her that he'll be able to give her some advice, since he's a member of the prince's court and knows about medicine. He also tells her about the "deformation rock" and "insanity powder" poisons, which are used in political struggles among the nobility. He explains that the deformation rock causes a person to lose blood, while the other two can cause a person's face to become ugly. The deformation rock is the last resort of his grandfather, who wants to protect him, so he asks about the other poisons, since they're all very complicated to make and refine. He doesn't know if they can be divided into good or bad grades, but he does know that the person who poisoned him with the "insane powder" and the "icecold heat powder" could be a noble or a royal member.
