The Ming Cult is a fictional cult and martial arts sect in a few of Jin Yong's wuxia books especially The Heaven Sword and Dragon Saber.
Fight with Huang Chang Edit
Huang Chang, a high ranking Song commander who had a high knowledge of marital arts led men under the order of the Song Emperor to wipe out the Ming Cult. Huang Chang and his army attacked the Ming Cult, killing several Wulin Martial artists in the process. This caused Huang Chang to have many enemies in the Jianghu (martial arts community) and these enemies killed his family for revenge. As a result, Huang Chang eventually hides and learns all his enemies' wugong, eventually writing the Nine Yin Manual.
