It tells the story of modern young man Chen Mo who traveled through time to become the magistrate of Qinghe County, but was overwhelmed by the complicated official duties. After activating the "strongest fishing system", he continued to launch lazy-style reforms based on the belief of "getting off work on time" - decentralization of powers and responsibilities, dividing people into acres, grid security, deep well irrigation, etc. However, every act of laziness was overly interpreted as foresight by his subordinates, which made Qinghe County more and more prosperous, and he unexpectedly became "Chen Qingtian" among the people. The county magistrate who only wanted to be in peace has created a model county with his "lazy administration".
