The story focuses on Ying Zhao, a descendant of the distant branch of the Qin royal family who was demoted to Daijun on the northern frontier. He is responsible for supervision, but he is caught in a fierce conflict between local forces and the new regime.
In Dai County, Ying Zhao not only had to face the restoration conspiracy of Zhao Jia, the leader of the aristocratic forces of the old Zhao state, but also had to deal with Xu An, the county governor who was submissive on the surface but actually had ulterior motives. From the "rebellion of weights and measures" to the "obstruction of trains on the same track", to the "difficulty of writing the same text" and the "disaster of taxation", Ying Zhao gradually grew up in crisis after crisis, transforming from a decadent and frustrated nobleman into a resolute official who adhered to Qin's laws and cared about people's livelihood. With the assistance of his loyal servant A Shi, he implemented the New Deal in a dangerous political situation, won the hearts of the people with the rule of law, and finally exposed the conspiracy and defended the foundation of national unity.
