The Qin family, a noble family in Dayan County, was plotted against by the Lin family. The head of the family became disabled, and the young master Qin Nan also had his dantian abolished. After losing all his power, Qin Nan came to Yuntian Sect alone to ask for the Qin family's treasure, the Burning Heaven Sword, but was insulted by Yuntian Sect and Lin Qinfeng. Qin Nan held the broken Burning Heaven Sword and cut off all ties with it. After going down the mountain, due to Qin Nan's tenacious character, the residual soul of the Qin family ancestor who was sleeping in the Burning Heaven Sword revived and taught Qin Nan the Shura Sword Technique, helping him awaken the blood of the Great Shura Supreme in his body and rebuild his dantian to continue his cultivation.
