Once Li Chengye activated the Secret Treasury, he rescued the fallen princess Yan Wushuang at the beginning. She is a legacy of the previous dynasty who was imprisoned in the palace and allowed to be slaughtered. He is an extremely powerful minister who possesses a secret treasure and can change his fate against the will of heaven. From then on, the male protagonist uses the secret treasury as a blade and power as a chess piece: kill traitorous ministers, quell palace rebellion, practice iron cavalry, destroy Beidi, establish the vassal king, and pacify the world! In the court, his words determine life and death; outside the battlefield, he defeats thousands of armies with one plan; when the empress comes to court, he protects the country with his hands. From a down-and-out concubine, to a king who stands side by side; from being precarious in the wind and rain, to uniting the world. The empress lowered her eyes: "My country is all given by you." Li Chengye bowed: "My lord, help the empress to conquer the world."
