On a bloody night when her family was destroyed, she was the only survivor in a murder case. From the daughter of a guilty minister to the official in the palace, Shen Yanqiu used forbearance as her armor and resourcefulness as her blade, navigating her way through the turbulent harem step by step, and finally became the minister who cared for the late emperor before his death.
The new emperor ascends the throne and a beauty comes to court. With an edict, the empress changed her from a female official in the harem to a "green hairpin censor" who was ordered to patrol the city. She traveled across nine states with Shangfang's sword: not only to redress the injustices of the people, but also to kill corrupt officials at the lower ranks; Searching for the orphans of the late emperor in the country - this is the last lifeline to maintain the legitimacy of the imperial power. It is also the ultimate mission hidden under the guise of "understanding the sentiments of the people", and it is her only bargaining chip to redress the injustice of the Shen family.
The road ahead is the trap of corrupt officials and the pursuit of hidden enemies. Behind him are the expectations of the empress and the undercurrent of the court. The green hairpin reflects the cold moon, and the horse's hooves trample on the wind and frost. She walks alone in the fog of injustice and conspiracy. When the truth gradually comes to light, and the hidden story of the family's destruction intertwined with the secrets of the royal family, she discovers: What she is pursuing is not only the traces of the prince, but also the truth that is difficult for her to face. And this life-threatening journey has long been destined to push her to the forefront of history. The road ahead is treacherous, and who can walk side by side with her.
The intention: to show loyalty and love to the common people by showing injustice to the lonely minister.
