The story takes place in an imaginary ancient dynasty - the Daqian Dynasty. Crown Prince Xiao Changfeng appears as gentle as jade, but is actually very scheming. After experiencing the pain of losing his mother at a young age, he understands the importance of power. In order to ascend to the throne, he had to deal with all forces step by step. Xie Yun, the daughter of the Grand Tutor, gradually became the master of the harem by virtue of her talents and family power after entering the palace, and started a complicated relationship with Xiao Changfeng full of intrigues and love-hate entanglements. Border general Murong Jin was loyal and upright, but he was involved in palace struggles and became a victim of the power struggle. Concubine Ning Zhao Wanrou came from a humble background and did whatever it took to get the upper hand. In the end, she could not escape her tragic fate. Emperor Xiao Chengye was suspicious and jealous, which led to the corruption of Chao Gang, and he eventually paid the price for his actions. The story runs in parallel with multiple clues, showing the cruelty of palace machinations and the complexity of human nature, as well as the struggle and helplessness of personal destiny in the game of power. In the end, Xiao Changfeng succeeded in ascending the throne, but he also paid a heavy price and became a lonely emperor. Even if he stood at the pinnacle of power, he could not make up for the emptiness in his heart, and the Daqian Dynasty also ushered in a new era under his rule.
