The concubine Su Qing rose to prominence by solving the mystery of Xuanji in the palace, but she was involved in the case of the disappearance of the imperial seal. The carnelian around her waist is involved in the mystery of the sudden death of the late emperor twenty years ago, and also reveals the truth about his bloodline as a saint of the witch clan. The dandy prince Zhao Wuji actually controls the Imperial City's dark network, and recognizes Su Qing as the masked girl who saved him from a fire when he was a child. The two play chess and rely on each other for life and death. Under the supervision of Empress Murong, they use poetry as a blade and power as a shield to tear open the chain of corruption in Jiangnan and dismantle the Xirong spy network.
When the red chalcedony illuminates the blood oaths of the previous life, and the Xuanji map hides the secrets of the people, Su Qing uses blood as a sacrifice on the burning ground to awaken the ancient formation, and finally destroys the jade seal to cast the monument of the people - the real eternal strength of the country does not lie in the golden seal of imperial power, but in the hearts of the people.
