Once he traveled through time, Shen Weixi became the koi carp that everyone in the Dayin Dynasty envied. Just because she had a face that resembled that of the former empress, the grief-stricken young emperor made her an unusual concubine and pampered her in the harem. Everyone said that she was lucky enough to be a substitute. Only Shen Weixi knew that this overwhelming wealth was a life-threatening talisman. Good news: The emperor is young, handsome, affectionate and dedicated, and the harem is as clean as a new house. Bad news: The object of his affection is not her. He always looked at the shadow of another person through her face at night. Even worse news: the Queen Mother regarded her as a demon concubine, the courtiers called her a disaster, and the concubines with prominent family backgrounds in the harem regarded her as a thorn in their side and a finger in their flesh, and greeting her every day was like being tortured. Shen Weixi (smiling): Okay, as long as the wages are paid in full, it's not impossible to be a substitute. During the day, she played the role of the gentle and conciliatory "first empress", coaxing the emperor to behave properly; at night, she closed the door, eating the eight-treasure snacks given by the emperor, and thinking about how to save her life in this weird palace and save some pension. Until one day, she discovered a diary of the late queen. There is no romantic romance in the diary, no imperial love, only shocking records line by line, revealing a huge conspiracy that swept through the harem of the previous dynasty. The death of the first queen was not an accident at all. Looking at the various forces behind her that were eyeing her, and then at the emperor in front of her who was "deeply in love" with her, Shen Weixi silently closed her diary. Forget it, I can't continue in this class. In order to survive, she decided to kill everyone and become her own boss!
