Zhou Lingfeng, a modern-day prodigy with encyclopedic knowledge, travels back to ancient times and is unjustly convicted and exiled to Mancheng, a barren and dilapidated frontier city. Plagued by famine, disease, and widespread poverty, this is a hopeless place that everyone avoids. With no system or supernatural assistance, he relies solely on knowledge a thousand years ahead of its time to survive in a chaotic age. He improves farmland, builds irrigation systems, prevents and treats epidemics, and revolutionizes people's livelihoods. Breaking through feudal ignorance, he gradually breathes life into the desolate border city, wins over its arrogant city lord, and gathers loyal subordinates. From a disgraced exiled official, he rises to become the lord of the city, overturning its seemingly inevitable downfall through nothing but ordinary human ingenuity and personally creating a prosperous golden age in this remote and desperate frontier.
