In the twenty-third year of Yong'an, the new emperor Xiao Che made an exception and promoted Xinke Tanhua Shen Qingci to the position of Crown Prince and Tutor. This woman with a hidden edge is actually the daughter of the former Taifu Shen Zhixing who died unjustly. She steps into the palace whirlpool with an old case - she is not only a pawn of the new emperor to check and balance the court, but also the chess player of the self-revenge plan.
In the East Palace, she needs to tame the stubborn Prince Jingyan and deal with hidden attacks from all sides: Wei Yong, the powerful prime minister, regards him as a thorn in his side and wants to use the war in Beidi to bring down General Liu and Concubine Shu to shake the crown prince's foundation; the virtuous concubine Su, who seems gentle but keeps secret about the past of the late empress; even Xiao Che, who promoted her, has complex feelings and deep calculations about the late empress hidden in his eyes.
From the confrontation in the Golden Palace to the arrow testing in the paddock, from the medicine residue in the imperial hospital to the old news in Yeting, Shen Qingci used resourcefulness as his armor and worked his way through the cracks. She protects the prince, investigates the cause of the late queen's death, joins forces with concubine Shu and the old tribe, and forges a path to justice in the fog.
When the secret of Pisces Pendant emerges, and old and new grudges are entangled, her game has already gone beyond revenge - she wants to clear her father's innocence, protect the prince, and in the power game of Zichen Palace, she wants to seek clarity for the world and fight for justice for women. And if there is a seemingly invisible connection between her and Xiao Che, it will eventually become a variable that stirs up the situation...
