During the Tianbao period of Tang Dynasty, the Anshi Rebellion broke out. Bai Yunfei, a disciple of Wanhua Valley, accidentally encountered An Lushan's minions when he came out of the valley due to what his master told him. He almost died, but was rescued by Murong Xue, a beautiful girl from Yiqi. Later, the two traveled together on horseback and fell in love with each other. Unexpectedly, Leng Yuechan, a disciple of Chunyang whom Bai had known since childhood, appeared. The relationship between the three people was entangled for a time, and Bai left Taiyuan in desperation and joined the ranks of the rebels against An Lushan.
