Han Qiu transmigrates to the Great Yu Dynasty and becomes the lowest-ranking Iron Guard in the Imperial City Directorate, holding the lowly rank of ninth grade, junior. Dirt poor, he also finds himself caught up in a new imperial policy urging marriage: any man who does not take a wife must be sent to serve in the army and guard the frontier. With no other choice, he follows his uncle to the imperial prison to 'pick' a female prisoner as his bride. Who could have guessed that when her red bridal veil is lifted, she would turn out to be a beautiful, refined young lady fallen on hard times? From then on, Han Qiu solves bizarre cases and battles powerful nobles while inventing new things, publishing newspapers, and promoting political reforms. Rising from an Iron Guard to an official in charge, and advancing from the countryside to the imperial court, he uses modern knowledge and a practical, results-oriented spirit to forge a path of effective governance in this ancient world. And the wives in his household, each of whom has emerged from prison, turn out to have backgrounds more extraordinary than the last.
