In the imaginary dynasty, the dynasty under the rule of Emperor Jing seemed to be prosperous, but in fact there was an undercurrent. In order to compete for the throne, the princes fought openly and secretly, each showing his own special powers. Qi Ye, the seventh son of the emperor, looks as gentle as jade, but is actually very deep. He secretly cultivates his own power and moves towards the center of power step by step. Shen Qingyi, the daughter of the Taifu, is smart, courageous, and has the world at heart. She and Qi Ye know each other, but they are involved in the whirlpool of power. Murong Yan, the daughter of the general who governs the country, has a heroic appearance and dares to love and hate. She loves Qi Ye deeply, but she is unwilling to become a tool for Qi Ye to fight for power. Li Dequan, the eunuch in charge of the ceremonial department, is powerful and scheming. He secretly controls the government and even covets the throne. In the whirlpool of power struggle, everyone is fighting for their own interests, and love, friendship, and family relationships have become fragile. In the end, can Qi Ye ascend to the throne? Can Shen Qingyi realize his ambition? Can Murong Yan find her destination? What will happen to Li Dequan?
