In the last years of the Celestial Dynasty, the people were in dire straits. Liu Zhifei, a small county idler who calls himself "Idle Cloud Yehe", meets Su Qingwei, who is disguised as a man, and gets involved in the palace turmoil by mistake. Unexpectedly, it was discovered that Jia Hu, an important minister of the DPRK, was secretly planning to usurp the throne. Liu Zhifei had an attitude of watching the excitement, but repeatedly relied on whimsical ideas and strange methods to resolve crises, and became the core adviser of Su Qingwei's side. After the rebellion broke out, Su Qingwei tried to restore the country, but her brother Zhao Tianlin had ascended to the throne and became independent. The brothers and sisters recognized each other and had their own ambitions. Liu Zhifei and his friends joked and laughed at life, scattered around the country, and found their own self-worth and emotional belonging in addition to the struggle - between the tide of the times and personal choices, they continued to write a passionate and humorous legend of the country.
