Su Wan, a modern forensic doctor, was reborn as a cowardly concubine of the Minister of Rites, but was forced to enter the palace draft to replace her sister Su Yao, who was secretly married to a pregnant woman. Carrying the crime of deceiving the emperor, she was walking on thin ice.
The palace is as deep as the sea, full of murderous intent. The plot to silence the eldest sister and her lover Liu Wenxuan goes hand in hand, and jealousy and strife among the beautiful women emerge one after another. Su Wan relied on her modern thinking and keen forensic insights to almost be framed during the primary election in Ye Ting. She endured and lay dormant, and cleverly broke through the frame-up plot. She also attracted the attention of the queen by accidentally saving a palace official.
Queen Shen's rewards and scrutiny are like double-edged swords, which not only bring her a moment of respite, but also draw her into a more treacherous whirlpool of power. Facing the drug-induced murder plot set up by the imperial doctor, Su Wan fought with her life and used the Ruyi jade gifted by the Queen to fight back, eventually forcing the mastermind behind the scenes to cut off her tail in order to survive.
After the storm, she was moved to the cold palace-like Qingyi Garden to "recuperate". Here, she meets a crazy palace maid who is unconscious but may know the shocking secret of "murdering the emperor's heir". A way out seems to be quietly emerging in the mist of this abandoned garden.
From a stand-in puppet to a chess player, in this deep palace of cannibalism, Su Wan could only use wisdom as a blade and tenacity as armor to fight step by step in the mountain of corpses and sea of blood, and blaze his own path to become a queen.
