In the Tianqing Dynasty, the throne was in turmoil and officials were constantly fighting for power. Xiao Zhimo, who has just been promoted, is surrounded by three main forces: the ruthless power minister Chu Cheng, the ambitious prince Duan Qi'an, and the illegitimate daughter of the royal family Lin Yuyao. Xiao Zhimo resolves court crises one after another through "hidden swords in smiles", and at the same time helps Huo Mingyuan, who comes from the market, to rise on the edge of power. Undercurrents are surging, and assassinations and counter-plots are emerging one after another. Lin Yuyao endured for many years and began to lay a revenge network, while Duan Qi'an grew up to be a hero in the dispute between brothers. In the end, the five story lines gradually converged, and the ultimate battle for power came. Under the vast political map, everyone will choose their destiny, whether it is the glory of swords and blood or the laughter and machinations.
