Gao Qiu
When Lu Zhishen passes by Cross Slope after leaving the imperial capital Dongjing to escape arrest by Grand Marshal Gao Qiu for thwarting his plan to murder Lin Chong, he eats in Sun Erniang's inn and is knocked out. Just when Sun is about to butcher the monk, Zhang Qing returns in time and stops her noticing Lu's unusual appearance. After reviving Lu and determining his identity, Zhang Qing suggests that he seek refuge with the outlaw band led by Deng Long at Mount Twin Dragons. Deng, however, blocks Lu‘s way to the stronghold. Lu kills and replaces him after getting into it with a ruse.
