S1·E13 Episode 13

Wu-chi has grown up and now knows some medical skill.

Chin Hua wants to take revenge on Chin-niu for he was not willing to cure her husband which caused his death. She injures Hsiao-fu and the others. But Chin-niu refuses to cure them. Wu-chi helps them but he fails.

Chin-niu has a wife called Nan Ku. He often cured the people who were poisoned by her. She was so angry that she left him. From then on, he decided not to cure the people other than that of Ming Clan.

Having known what Chin Hua has done, Nan Ku goes back to tell her husband. When she knows Chin-niu goes against her, she poisoned herself. Since Chin-niu cannot cure her of the poison, he is willing to die with his wife.
