In the capital of the Ming Dynasty, Du Jinyi, a young man from the city, accidentally became a Jinyiwei. When he first entered officialdom, he relied on his market wisdom to resolve many crises, and he was constantly involved in power struggles. Under Chu Xiyue's guidance and encouragement, he formed a humorous and high-powered team with his best friend Liang Zian and the eccentric Jianghu Li Sucao, and worked in the three worlds of officialdom, rivers and lakes, and temples. Faced with the pressing pressure of the powerful Zheng Dacheng, Du Jinyi used humor and courage to avoid danger, step by step towards the peak of growth, and finally exposed the machinations and conspiracy, kept his original intention in the dark and rainy days, and gained friendship and love. It is simple and clear but profound, and the whole process is full of laughter and excitement.
