To convey his gratitude, Chao Gai sends Liu Tang to deliver one hundred pieces of gold each to Song Jiang and Zhu Tong, who has also aided his escape. Liu also brings along a letter from Chao for Song. Song is shocked to find Liu greeting him on the street one night. He refuses to take all the gold, accepting only one piece as a token. That night he is forced to go to sleep with Yan Poxi by Yan's mother. Yan discovers Chao's letter, which reveals Song's involvement with the outlaws of Liangshan. She threatens to report him to the authorities unless he meets three demands: divorce her and allow her to marry Zhang Wenyuan; let her keep all the things he has given her; and hand over all the gold pieces he received from Chao. Song agrees to the first two but could not accede to the third as he has accepted only one gold piece. As Yan refuses to believe him and repeatedly threatens to expose him, Song becomes agitated and kills her with a dagger that he always carries in his bag. He flees to hide in a pit in the house of his father. Zhu Tong, who is sent to arrest him, locates him in the vault as Song has once told him about it. But Zhu lets him go. Song runs away from Yuncheng and becomes a fugitive.
