At the end of the Northern Song dynasty, the Song and Jin armies clash, and turmoil sweeps through the martial world. Ten years after Qiao Feng took his own life at Yanmen Pass, Duan Yu rules Dali and reminisces about his old friends. Then Wang Yuyan suddenly disappears, and a jade pendant engraved with the words “Yanmen” casts suspicion everywhere. Xu Zhu, now master of the Vulture Palace, puts down a rebellion in the Tianshan Mountains and uncovers a secret letter signed “Xiao Yuanshan,” revealing the mystery of how the hero survived. The Xuanming Sect rises in the Western Regions, wielding sinister, secretive Gu sorcery and plotting to throw the Central Plains into chaos, while remnants of the Murong clan lurk in the shadows. Their descendants, Duan Xi, Xu Wu, and Xiao Lie, carry on their fathers’ unfinished mission and join forces to defeat their enemies. Before Shaolin Temple, the Dragon-Subduing Palms thunder once more. The mournful song of Yanmen Pass rings out, and the spirit of chivalry burns anew. What makes a hero? As long as the heart does not fall, the martial world will endure forever.
