Lin Lan, the lowest-level disciple of the Shaman Realm in Xuan Ming Que, was deprived of his cultivation resources by his elder sister Lin Wan in public, and even the lowest qualifications for sacrifice were deprived of him. The iron law of the Witch God Contract is there: without sacrifice, there is no way to be promoted. She has the blood of the Nine-tailed Sky Fox, but due to the curse of the Lone Star, her relatives and classmates suffered misfortune because of her, and everyone shunned her. Only Yin Jiuyou, the young handyman who was called the "dumb and loyal dog", silently shielded her from the open and secret attacks, and even did not hesitate to use his own blood and blood in exchange for a chance to sacrifice for her. Lin Lao thought she could survive by enduring to the edge, until Lin Wan designed her to be involved in the desperate battle of the Nine Que Trials - either sacrifice all her cultivation, or cut off her tail to survive. And having one's tail cut off means that one's cultivation level is halved, but one can perform forbidden witchcraft that only the nine-tailed sky fox can trigger. "If you cut off one tail, I can still kill you." She cut off the first tail in front of everyone, and the trial platform was stained with blood. From that moment on, the entire Immortal Palace fight in the Witch God Period was dragged step by step into the abyss of Nine-Tailed Duantian's revenge. And the secret of Yin Jiuyou that has been hidden for three hundred years will be gradually revealed with every cut of her tail...
