Cai Jiu nearly falls for the ruse. However, Huang Wenbing points out that the seal on the letter is not an appropriate one between father and son -- a sign that the letter is fake. Furious that Dai Zong has betrayed him, Cai Jiu orders his arrest. At Huang‘s urging, Cai Jiu sentences both Dai and Song to death. Meanwhile, Wu Yong has realised the mistake in the letter. He sends several chieftains to rescue the two in Jiangzhou. Just when the executioners are about to swing their knives in the public execution, Li Kui jumps out and kills them. The Liangshan chieftains surrounding the place also rush forth to fight off the soldiers. Dai Zong follows the outlaws back to Liangshan.
