The Dayin Dynasty suffered from internal and external troubles, frequent natural disasters, corruption in the court, and the people were in dire straits. A draft sent the commoner girl Ling Yunxi to the deep palace. Ling Yunxi is born with a kind heart. She is a thoughtful planner, but she is willing to endure the turmoil of the harem, just to get a glimpse of the peak of power and turn the imperial power into a tool to save the world. Emperor Chu Yuanyao is cynical on the surface, but in fact he has seen through the corruption of the court, and is looking for a confidant who can walk side by side with him. He and Ling Yunxi hit it off like old friends, but they often had conflicts due to the collision of personalities and ideas. The two went from tit-for-tat to fighting side by side, becoming each other's support and salvation.
