After his defeat by the bandits of Liangshan Marsh, the imperial general Huyan Zhuo flees to Qingzhou (in present-day Shandong) in hope of redeeming himself by wiping out the bandits there. One of the strongholds is Mount Twin Dragons, which, finding Huyan a tough opponent, requests help from Liangshan. Song Jiang, Liangshan's then second-in-command, comes to Qingzhou with a force and captures Huyan. The bandits of Mount Twin Dragons, led by Lu Zhishen, are absorbed into Liangshan.
