Over a hundred years ago, Hongye, the King of All Demons, met and fell in love with Ning'an, a human princess. Hongye, carrying the beautiful vision of peaceful coexistence between the two races, prepared to marry Ning'an, only to be betrayed at their wedding and stabbed to death by Ning'an. Over a hundred years later, human dynasties changed, but the fear and disgust towards the demon race only increased. Xiao Yao, a human woman traveling the world with her father, accidentally entered the Youning Cave, which sealed Hongye's primordial spirit, awakening the King of All Demons. Having regained his human form, Hongye vowed never to trust humans again and to find the Jade Spring, which could enhance the demon race's cultivation, leading them to rise again. However, he never expected that Xiao Yao, who looked exactly like Ning'an but had a completely different personality, possessed half-demon, half-human blood, stirring all his emotions. To uncover the truth about Xiao Yao and his past lives, Hongye detained Xiao Yao in the Spirit Race's territory, "Valley of Ten Thousand Spirits."
