In the first year of Yongxi's reign, the general family of the Yu family was convicted overnight, and all of them were taken to the execution ground, and the streets were stained with blood.
As the orphan of a guilty minister, Yu Wanning managed to survive three years without her last name, dormant in the palace, and found the position of a female imperial official. Holding the incomplete account pages in her hand, she traced the clues of the unjust case step by step, vowing to clear the family's name.
The domineering eldest princess Sima Mingshu was the mastermind behind the Yu family's murder. She secretly amassed dead men and squandered the treasury's money. When she became aware of Yu Wanning's pursuit, she repeatedly set up traps and ambushes to eliminate the source.
The emperor Sima Jingyuan, who was sitting high on the throne, watched the chess game with cold eyes. Back then, in order to check and balance his relatives, he acquiesced in the secret court's special edict to accuse Luo Zhi, and now he deliberately used Yu Wanning's hands to weaken the eldest princess's authority. He secretly protects her life, but is also afraid that she holds the secret evidence that could shake the imperial power. There is a game between the monarch and his ministers, and affection is wrapped up in calculations.
Xie Yunlan, a Qingliu civil servant, abides by national laws, discovers suspicious points in old border disputes, and becomes Yu Wanning's secret ally. He works in many ways to preserve personal and material evidence for her.
Autumn hunting in the Western Mountains, among the withered pines on the cliffs, a fragment of a secret courtyard appears.
This thin piece of paper is not only a sharp blade that can overthrow the relatives, but also a forbidden object that can overturn the emperor's authority.
On the one hand, there is a blood feud that must be avenged, and on the other hand, it is the price of turmoil in the country.
Yu Wanning stands in the deep palace and the court, not clinging to the powerful, not longing for the throne, but holding the certificate to enter the game, as an orphan girl, playing against the emperor, fighting against relatives, seeking justice and settling the world in the turbulent imperial city.
