Ling Xian'er, a modern career elite, unexpectedly transmigrates into the body of a disgraced consort in the cold palace of the Mo Kingdom, awaiting execution by imperial decree. She shares the body with its former owner's lingering soul. The original owner was gentle and devoted, but Emperor Liu Qufeng wiped out her family, and she died consumed by hatred. Their souls take turns asserting control, one cold and the other fierce, sharing a single body.
Meanwhile, Empress Shen Zhiwei, Noble Consort Su Wanli, Consort Shu Lu Xingyao, and Consort Li Song Ningshuang, four concubines who were abused by a foolish emperor and died tragic deaths deep within the palace, have all been reborn at the same time.
United by a shared blood feud, the five women form the most ruthless revenge alliance the imperial harem has ever seen.
