Mirror of the Demon Concubine

Under the desperate plea of ancient concubine Nan Yue across time and space, modern girl Xu Xiaoyue agrees to swap bodies with her for a year to help her out of trouble. After a year, when Xu Xiaoyue returns to her own body, she finds her savings squandered, she is pregnant with a vagrant's child, and she is sick with a fatal disease. Meanwhile, Nan Yue, who rose to become the Empress with her help, mocks her kindness and low status. On the brink of death, Xu Xiaoyue discovers she has been reborn back to the very day she first swapped bodies with Nan Yue to become the concubine.
