Chang Yuchun brought clothes and red bean cakes to Wuji. Wuji asked Hu Qingniu why he didn't treat people from famous and upright sects, and Hu talked about his sad past. He had been alone for three days and three nights (the head of Huashan Sect, Qian Yutong), and even betrothed his sister to him, but that person turned his kindness into hatred and killed Hu's sister. In the middle of the night, Wang Nangu saw that there was an outsider (Wuji) in Qingniu's house, so she blew poison gas to knock him out. The next morning, Wuji brought food to Qingniu, and Qingniu pretended to have smallpox and didn't allow Wuji to get close. Wuji looked up smallpox in the Yellow Emperor's Classic of Internal Medicine. Jinhua Granny invited Xiaofu, Kongtong Senior Jian, Huashan Big Brother Xue, the Divine Fists, the Beggars' Gang, etc. to an inn, and beat them with golden flowers, asking them to go to Butterfly Valley to find Hu Qingniu for treatment. Everyone came to Butterfly Valley, but Hu Qingniu refused to treat them. Xiaofu and Buhui came later, and Wuji helped him treat them, but he refused to treat other people without authorization and asked Hu for instructions. Hu said that he was being treated outside the house but he didn't care. Wang Nangu (Qingniu's junior sister and wife) was dissatisfied with Wuji's actions and secretly poisoned the medicine, which made his condition worse. Fortunately, Wuji found out. Wuji came to see Qingniu's injury. Qingniu gave him a prescription, including Angelica (it's time to go back to China), Polygala (aspirations are far away), Shandi (only Shandi), Duhuo (only Duhuo), Saposhnikovia (to prevent the news from leaking out), and pangolin as the medicine guide at the second watch (the pangolin escaped at the second watch). He took it in a hurry, but in fact it let Wuji escape. Nangu thought Hu was against her, so she tied Hu up and took the poison herself. Hu knew that his wife was always against him and that life was boring, so he took the poison and wanted to die. At this time, Granny Jinhua arrived.
