Du Letian was originally an astute but lazy "grassroots" detective in the rural market. He was accidentally involved in an unsolved case. In order to save the people, he exposed the crimes of the powerful and was promoted to the position of county magistrate. With the help of Song Xueyi and other partners, Du Letian solved bizarre cases one after another, and gradually attracted the attention of the court. As the case escalates, Lotte is caught in the dangerous decision between officialdom's intrigues and civilian suffering, and uncovers his mother's unjust case in the past and a greater conspiracy. In the intertwining of positive and negative, humor and bitterness, Du Letian continued to grow between officialdom and the people, writing a story of laughter and tears in which grassroots counterattacks and wise decisions were made.
