The leader of the Kunlun Xuansheng Sect, the largest sect in the Western Regions, is highly skilled in martial arts and ruthless. He massacred the entire clan but left behind a younger sister, Xuan Junxi, who had a face that brought disaster to the country and the people and an otherworldly dancing posture. After regaining the frontier fortresses, he unified the Western Regions under his command. The emperor of the Central Plains sent the prince to come and marry Xuan Jun's sister who was hiding in the church. On the way back to the Central Plains, Xuan Junli killed the prince's wedding team alone and killed the prince off his horse. He took his sister back to Kunlun, and the war between the Central Plains and the Western Regions was about to break out. In order to protect his sister, Xuan Junxi transformed from a weak woman with no strength to become a witch from the Western Regions who was good at psychedelic arts. Later, she used the identity of a dancer from the Western Regions to go to the Central Plains alone to assassinate Emperor Ming Youxian. However, she failed and was imprisoned in the Central Plains.
