Gongsun Sheng
Liangshan is challenged by the outlaw band of Mount Mangdang (芒碭山; north of present-day Yongcheng, Henan) led by Fan Rui, Xiang Chong and Li Gun. Xiang and Li defeat Shi Jin, who is sent as the vanguard. Song Jiang arrives with the main force, which includes Gongsun Sheng. Gongsun arrays the Liangshan troops in a formation that traps Xiang and Li when they charge into it. Fan Rui, who has used his sorcery to aid the duo in their attack with strong winds and flying pebbles, could not extricate them. Gongsun also engulfs Xiang and Li in darkness causing them to fall into a pit. The two surrender moved by Song's warm treatment. They also persuade Fan to lay down his arms. In admiration of Gongsun's august magic power, Fan requests to be his apprentice to study sorcery and Taoism.
