Yanmen Pass
Towards the end of the novel, Yelü Hongji plans to invade the Song Empire and wants Xiao Feng to support him, but the latter refuses and attempts to dissuade him to prevent bloodshed. The Liao emperor imprisons Xiao Feng and decides to proceed with the campaign. In the meantime, Azi escapes from Liao and seeks help from Duan Yu, Xuzhu and their allies. Impressed by Xiao Feng's righteousness, they manage to rally martial artists from throughout the "wulin" to join them in rescuing Xiao Feng. Even though the mission is successful, they are ultimately outnumbered and trapped by Liao forces at Yanmen Pass. Xiao Feng takes Yelü Hongji hostage and forces him to promise that there will be no war between Song and Liao for as long as he lives. He then commits suicide while Azi follows suit.
