Sixteen-year-old Taoist priest Yuqing went down the mountain for the first time and was dragged by villagers to collect demons. When he went to the forest, he met an evil man. He saw that this man was a fox demon, so he thought he was right and wanted to take him in. The fox demon saw the little Taoist priest amused and easily subdued him. After teasing and taunting him for a while, he thought the Taoist priest was really cute and left without hurting him. Yuqing was left alone and was very angry and decided to go back to the mountain gate to practice harder. However, he didn't know that what he met was the fox king Chi Xiao who corrected the path and not the murderous fox he thought. And Chi Xiao was also passing by and heard that fox monsters were harming people in this area and planned to capture them and take them back to teach them a lesson. Ten years later, the little Taoist priest grew up to be a great Taoist master. The master calculated that someone who was destined to be both immortal and doomed appeared in his fate, so he asked him to come down the mountain again. At this time, Yuqing had already mastered Taoist swordsmanship. As long as he had this immortal fate, he could ascend to immortality. And when he went down the mountain again, he met the Chixiao that had provoked him back then. So the Taoist priest was so angry that he gritted his teeth and wanted to fight him. But he didn't know that this fox was his immortal calamity.
