The orphan of the Nine-tailed Fox "Su Wanying", in order to find the Nine-tailed Lotus to save her life, disguised herself as a servant disciple of Lingxi Mountain and sneaked into the mountain gate. She originally wanted to avoid the villain Ye Shenyuan, but when she went down the mountain to get rid of evil spirits, she accidentally saved him who was seriously injured. At that time, Ye Shenyuan was disguised as an ordinary monk, and Su Wanying did not recognize his identity. During the relationship, Ye Chenyuan was moved by Su Wanying's innocence, changed from his previous cruelty, and secretly protected her. But the elder of Lingxi Mountain discovered Su Wanying's nine-tailed fox bloodline and wanted to sacrifice her to the "Demon Suppressing Pillar" to strengthen the seal. At the critical moment, Ye Shenyuan appeared, not hesitate to become the enemy of the three realms, and protected Su Wanying behind him. Su Wanying was shocked to realize that the "ordinary monk" she had always relied on was actually the rumored murderous villain. Behind Ye Chenyuan's abnormal behavior, there is a secret from a hundred years ago: he was saved by Su Wanying's ancestor, and this approach was not only to repay his kindness, but also to make him moved.
