Xue Lanxi and Xue Jingshu are the twin daughters of the Duke's Mansion. The elder sister, Xue Jingshu, was prophesied at birth to be a lucky star sent by Heaven, beloved by all, yet plagued by illness. The Sage of Heaven claimed this was because her younger sister, Xue Lanxi, was born at an extremely Yin time, making her a malevolent star whose fate brings misfortune and clashes with Xue Jingshu's. The Celestial Master said that only by subjecting Xue Lanxi to endless suffering could Xue Jingshu's pain be alleviated. Moreover, he declared that if Xue Lanxi were killed on their 18th birthday, Xue Jingshu would be completely cured. On that fateful day, Xue Lanxi was cruelly murdered by Xue Jingshu. However, she encountered a fox spirit that allowed her to be resurrected and reborn to seek revenge. In this life, Xue Lanxi is determined to take everything from Xue Jingshu, including the man she loves most, Xiao Yu Heng, and ensuring that Xue Jingshu meets no good end.
