Huyan Zhuo
The Song Court orders Huyan Zhuo to lead a military attack on Liangshan Marsh to stamp out the outlaws. The general deploys a special cavalry, which comprises groups of armoured horses linked by chains. As the horses charge forward as consolidated units, their stampede overwhelms the Liangshan force. Song Jiang, then Liangshan's second-in-command, has to hole up in the stronghold, relying on the marsh as a marsh, to find a way to counter the cavalry. Tang Long suggests his cousin Xu Ning, who is an ingenious user of the hooked lance, could fell the cavalry with the weapon. Agreeing with Tang's plan, Song sends him, Dai Zong, Shi Qian and Yue He to Dongjing to lure Xu Ning to Liangshan.
