Princess of the Western Regions

In her past life, the royal court identified Yan Xi, a Western Regions saintess possessing the Sacred Yin Body, and gifted her to Prince Mu Beiyun of the Northern Ling Kingdom as a concubine to cure his Yang Poison. However, Mu Beiyun only loved his wife, Jiang Xueyao, and treated Yan Xi with cold indifference. After an accident, Yan Xi became pregnant. To consolidate her status, Jiang Xueyao colluded with her lover and cousin, Wei Ping, to frame Yan Xi using poison arts. Reborn, Yan Xi cultivates the 'Peach Blossom Charm,' a poison that resists all poisons and can be turned back on its users. She then meets Mu Beiyun ahead of schedule.
