盧俊義
Liangshan's chief Chao Gai was ambushed and killed by Shi Wengong. His fellows vow to avenge him. The current "de facto" leaders of Liangshan, Song Jiang and Wu Yong, decide that given Shi Wengong's skill, Lu Junyi (Shi's former fellow student) will be the best person to assist them in taking revenge. The outlaws also note that if they succeed in recruiting Lu Junyi, they will also win over Lu's servant, Yan Qing, who is also a formidable martial artist.
