However, Li Gu bribes the guards escorting Lu Junyi to Shamen Island (沙門島; present-day Changdao County, Shandong) to murder him along the way. Lu's servant Yan Qing kills the escorts when they are about to finish him off in a wood. But Lu, who is weak from days of torture, is captured again at an inn when Yan goes look for food. This time, he is immediately sentenced to death. Just when Cai Fu is about to swing his sabre to chop off Lu's head at a public execution ground, the brothers are gladly stunned by Shi Xiu of Liangshan, who storms towards them in a lone attempt to save the squire. The Cai brothers, who do not want to be in the black book of Liangshan, subtly loosen the ropes on Lu and allow Shi Xiu to drag him away. But the two are overwhelmed by the soldiers and captured. Grand Secretary Liang Shijie, the governor of Daming, decides to keep them alive as bargaining chips should Liangshan mount an attack. The Cai brothers take good care of Lu and Shi in prison.
