In this chapter, we learn that the young master of the Luo family has been forced to leave the dungeon by his master. The young master asks the butler of his hand if he can cure his father. The butler answers that he can, but that he must obey him in the future. He tells the butler that he has come to find out that his father has a foreign substance in his body. He says that the foreign substance is a snow silkworm, a rare species of poison worm that lives in very cold lakes. Only a few people knew that the snow silkworms were used as a poison, and that it would stay inside a host until the host was dead. This is why it was called a poison worm. The old man is carried out of the dungeon.
