In ancient times, the God of Chaos fell, the Yang soul was reincarnated as an immortal, and the Yin soul was reincarnated as a demon. And Su Nian, the legitimate daughter of the Su family, carries this demigod's body alone.
At the Hairpin Spiritual Testing Ceremony, Su Nian was found to have lost all his spiritual roots. His engagement was canceled in public by Xuan Yan, the elder brother of the Taixu Immortal Sect, and he became a laughing stock. No one knew that the black and red light on her fingertips was a sign of the awakening of the yin and yang symbiote.
Being bullied, humiliated, and robbed, Su Nian gritted his teeth and endured, rubbing his mother's hairpin every night - the cracks in the hairpin's body hid the truth about his life experience and the destruction of his family. She is not a loser, but the only destined person in the Three Realms who can cultivate both Yin and Yang.
She began to tear off the good-for-nothing cloak with her own hands: refuting those who broke off the engagement in public, joining the Immortal Sect, fighting saints, crushing geniuses from all sides, investigating the cause of her mother's death, and avenging the family's destruction. On the day when the dual cultivation of immortals and demons was first achieved, the three realms were shaken.
Immortals, demons, humans, and ancient times, four eyes fell on her one after another - Xuan Yan, the elder brother of the Taixu Immortal Sect, broke off the engagement with his own hands, but saw the light change again, and regretted it too late; Mo Yuan, the demon king from the demon world, came on the moon and recognized her as an old acquaintance from the past life; Xiao Jingheng, the emperor of the human world, regarded her as a pawn, but was trapped; Wuming, a mysterious ancient existence, called her "old friend", but her real name is unpredictable.
Four husbands chased their wives at the crematorium, lining up from the human world to the ninth heaven. But Su Nian just wanted to ask: What did her mother leave behind? Who killed her? Who is living inside her?
In Chapter 50 of the first season, the secret of the half-body will be revealed to the world; the door of chaos will be opened in the direction of her true hometown.
