Суншань
The Mount Song Sect () is headed by Zuo Lengshan (左冷禪), who is also the nominal chief of the alliance. It is based on the same mountain as the Shaolin Sect but situated on a different peak. The ambitious and ruthless Zuo Lengshan wishes to consolidate power by intimidating the other four sects to submit to him and merge into the Mount Song Sect. He sends his spy Lao Denuo to infiltrate the Mount Hua Sect and steal Yue Buqun's Violet Mist Divine Skill manual, and instigates the exiled Sword faction members of the Mount Hua Sect to challenge Yue Buqun. He bribes members of the Mount Tai Sect to turn against their leader Tianmen, who is betrayed and killed by his own men during a special ceremony. Zuo Lengshan also sends his followers to assassinate Dingjing, one of the three leaders of the (North) Mount Heng Sect. In an earlier chapter of the novel, Zuo Lengshan confronts Liu Zhengfeng of the (South) Mount Heng Sect during the latter's retirement ceremony to force him to surrender. Zuo Lengshan is eventually defeated by Yue Buqun and blinded. He is killed by Linghu Chong during the chaotic scene when they are trapped by Yue Buqun in a cave.
