Chen Mo, a modern-day overworked corporate employee, transmigrates into the body of a county magistrate. Hoping to take it easy and coast through life, he unexpectedly binds himself to the Ultimate Slacking System and the ancient divine beast Xiezhi. Determined to slack off once and for all, he invents cement for road construction, implements the policy of taxing households by land rather than population, introduces grid-based public security management, and uses alcohol for epidemic prevention. Although he only intends to avoid work, he repeatedly achieves astonishing feats. From governing a county to managing flood control, his seemingly effortless, overwhelmingly advanced methods leave his subordinates imagining all sorts of hidden brilliance and his colleagues utterly speechless. Meanwhile, he rises from a lazy county magistrate to ever-higher office, ultimately being forced to reach the pinnacle of his career.
