A vision came from the sky when the fox girl Chi Heng was born. She had a strange fragrance since she was a child, and she was also a nine-tailed red fox. Legend has it that since her birth, she was invulnerable to all poisons and had deep internal strength. But there have been very bad rumors about her, saying that she was born with a demon seed in her body, and her birth was unknown, so her mother died when she was born. After her birth, the tribe was defeated, and the Fox King was poisoned and became disabled. Since then, the snake tribe has dominated the demon world, and she has become a disaster star in the eyes of the tribe. In order to save her people, she went to Yunshan to become an apprentice and seek the stone of longevity. Until she met Cang Jiuchen, the god Jiuchen respected by all nine states, was it her fate or her fault?
