Three hundred years after the war between gods and demons, the world of gods was sealed and the world of demons withered. The ancient demon god Jiang Yin proclaimed himself Dual Lineage and infiltrated among the disciples of the No. 1 Mountain in the fairy world. He repeatedly teased the cold and aloof god fox chief disciple of Beicong Mountain. She accidentally caught the divine fox showing its demonic form in a forbidden area. After that, the divine fox became a god and a demon. He stayed quiet during the day and avoided suspicion, but when he appeared as a demon, he would imprison and threaten her and question her. The divine fox will also secretly tolerate Jiang Yin and others' teasing. In the end, Jiang Yin connected both veins to restore the demon god to his rightful position, and entered the divine realm in wedding clothes. The god fox was actually dressed in white clothes stained with blood, and snatched the marriage under the blue sky.
