The Zhou Dynasty was prosperous on the surface, but in reality there was an undercurrent. The prince Li Ke was arrogant and domineering, and the ministers in the court were divided into the princeling party and the Qi prince party. The two factions were at odds with each other. Although the King of Qi, Zhao Yu, was a prince, he was neglected since his childhood because his biological mother was from a lowly background. In order to change his destiny, he had to be cautious and step by step. He gathered many wise men, secretly accumulated strength, and launched a thrilling battle for imperial power with the prince. In this struggle, he not only has to face the overt and covert attacks from the prince, but also has to be wary of the conspiracies and intrigues in the harem, as well as the game between the various forces in the DPRK and China. In the end, Zhao Xun relied on his extraordinary wisdom and firm will to climb to the pinnacle of power step by step and became the emperor of the Zhou Dynasty. However, when he ascended the throne, he discovered that there was more loneliness and helplessness hidden behind power.
