In this chapter, we learn that Dr. Su has found a remedy for elephantiasis, a disease that causes fever and nausea. We learn that this remedy is called "the thousand jungle grass" and that it has been grown in patches at his house. We also learn that Mi Yochu is suffering from white hair, which is a sign that he has been infected with elephantiasis. He is not sure what to do, since he is immune to "a hundred poison" , but he does know that if he were to die, he would have to drink the poison. Mi Yocha also tells us that the poison is a "wild rabbit- antidote" .
