In the Dahuang Kingdom, where women are superior to men, a legendary story about power and love unfolds. Yun Zhao, the daughter of the Third Emperor, is extremely powerful but knows nothing about government affairs. She is dressed in red with a ponytail and a scar between her eyebrows. She can kill tigers with her bare hands but is only afraid of spiders. She was urgently recalled from the border and accidentally rescued Xie Qinglan, the most talented man who was as gentle as jade but concealed a sinister conspiracy. This "male Durban" top student with an abacus hanging around his waist is actually a master of hidden weapons and has a photographic memory. Since then, the fate of Yun Zhao has been intertwined.
After returning to the palace, Yun Zhao faced a cruel political struggle. The empress was seriously ill, and the two imperial sisters fought openly and secretly for the throne. She made a fool of herself in court because she didn't understand government affairs, but with the secret help of Xie Qinglan, she was ordered by the empress to participate in political affairs. Faced with the rumors of being a "bastard", Yun Zhao reached a deal with Xie Qinglan: she would protect him and he would help her pervert the government. From court arguments to late-night sparring, from spotting a beautiful spy to jointly investigating household deficits, the two develop a secret love in crisis after crisis, and their ambiguity continues to heat up in famous scenes such as night talks in the library and rides together.
As the plot progresses, Yun Zhao goes south to investigate the salt tax on the order of the empress, and goes deep into the rivers and lakes with Xie Qinglan disguised as a caravan couple. On the way, they encountered mountain bandits who robbed the road, stayed overnight in a ruined temple, and experienced jealous cold wars at a Jiangnan banquet. However, they also became more and more deeply attached to each other while protecting each other. And as the secrets of their life experience are exposed one after another - Xie Qinglan's son of the former imperial master and his mixed-race identity, and the truth that Yun Zhao's biological father "died in battle", the two not only have to deal with the conspiracy of the court, but also fight against the threats of Tingxuelou and southern Xinjiang forces.
After experiencing the test of life and death, Yun Zhao grew from a political novice to a wise ruler of the country.
