Lu Chen is bound to a system and takes out a loan of 100 million, with 48 hours to purchase supplies before traveling through time. In the modern world, he humiliates a gold-digging woman, teaches the underworld a lesson, empties fuel tanks, and forcibly teleports away while being surrounded by the police. In ancient times, he assumes the identity of the murdered magistrate of Qingyuan County, only to be challenged by the deputy magistrate, the military commandant, and the registrar as soon as he arrives. The system issues a chain of missions: helping an elderly man enter the city, buying a young woman being sold into servitude, and teaching Constable Qin a lesson. Each completed mission earns him points and strengthens his physique. However, the 100-million loan converts into 100 million points, which he must repay within one year—or be erased.
