Gongsun Sheng
Angry over the injuries of his men but appreciative of Zhang's stone-flinging skill, Song Jiang is determined to capture and win over the commandant. Wu Yong, Liangshan's chief strategist, proposes setting up an ambush. When told that a convoy of ration is approaching Song Jiang's camp, Zhang, seeing a chance to cut off Liangshan's food supply, leaves the city to intercept it. Lu Zhishen, who is leading the convoy, is knocked over by Zhang's stone. Wu Song drags Lu away. Thinking he could succeed a second time, Zhang Qing moves to attack Liangshan's ration-loaded boats moored at a riverbank. But Gongsun Sheng engulfs him in darkness with his magic. Losing his way, Zhang Qing falls into the river and is captured.
