Thousands of years ago, the demon clan caused trouble in the three realms. The God of War went to pacify it, and Fairy Chun'an, the youngest daughter of the Immortal Emperor, came to help. The demonic chaos was calmed down, the Fairy Queen returned, and the God of War disappeared. Immortal Fairy moved into the Mansion of the God of War, and gave birth to twins, Zixuanmo and Zixuanyu. They were born with golden eyes of pure immortals. Zixuanmo was born with the ability to speak and prophesy, and inherited the ability of the God of War. Zi Xuanyu is inferior to him, but he can communicate with animals and plants and has the ability of an immortal queen. Just after Zi Xuanmo gave birth, she said, "The father is in the Demon Realm." Immortal Fairy left her brother and daughter in Prince Zhan's Mansion and left.
