Yue He, a jailer in the prison, happens to be related to them, his sister being the wife of Sun Li, whose brother Sun Xin is married to Gu Dasao, a cousin of the Xies. Sun Li is the commandant of Dezhou's garrison. Yue takes the news of the Xies to Sun Xin and Gu Dasao. The couple rope in Zou Yuan and Zou Run to help in the rescue. They also pressure Sun Li to join in. On the day of rescue, Yue He opens the prison gate to let in Gu Dasao, who pretends to bring food to the Xies. After admitting her, Yue unlocks the manacles that shackle the Xies to a bed. Once released, the Xies are like tigers released, charging out of their cell and smashing the chief warden to death as Gu creates havoc in the jail compound. Meanwhile, Sun Li and the others launch attack from the outside. After pulling off the rescue, the group kill Squire Mao and his family and flee to join the outlaw band of Liangshan.
