As the daughter of General Zhenyuan, Shen Zhaoning has been familiar with military books since she was a child and has a deep heart. In order to protect the peace of the border, she changed her name to "Mr. Zhao" and sneaked into the court as a counselor to assist the seemingly cynical sixth prince Xiao Jamyan. Jamel Xiao knew that the road to the throne was full of thorns, but through Shen Zhaoning's planning, he gradually revealed his imperial talents.
Above the court, there are undercurrents of forces from all sides. The prime minister formed a clique for personal gain and intended to control the young emperor; the queen mother did anything to protect the power of her relatives. Shen Zhaoning circled around in the whirlpool of power and conspiracy, and saw through the conspiracies again and again, but he also fell into dilemma because of it. When the war on the border becomes tense and her father sends a secret letter asking for help, and Jamel Xiao's ascension to the throne is at a critical moment, she must make a choice between her family and her ideal monarch.
As they get along day and night, Jamel Xiao and Shen Zhaoning gradually fall in love, but due to their status and situation, they have to bury their love deeply. They worked together to smash the prime minister's conspiracy to usurp the throne, but before the peak of their power, they were estranged due to their opposing stances. When Jamel Xiao finally ascended the throne, Shen Zhaoning took off his fine clothes and returned to the frontier. Inside and outside the palace walls, they used their own ways to protect the mountains and rivers, and the unspoken deep feelings turned into the mountains and rivers policy in each other's hearts that would never fade.
