In the third year of the Yongli reign, rain leaks through the ruined temple in Wuzhou, and the Southern Ming has fallen into the abyss of a dying dynasty. In the history books, Zhu Youlang will spend twenty years on the run, held hostage by warlords, caught in court infighting, and pursued by the Eight Banners, before Wu Sangui strangles him in Kunming, leaving behind the eternal lament of a fallen dynasty. Lin Yue, a modern graduate student with dual specialties in military history and metallurgical engineering, transmigrates into the body of this last emperor and binds himself to the [System for the Survival of China and Its State]. From the start, he faces a desperate situation: seventy battered soldiers and no food for three days. Yet he manages to extend the dying Ming dynasty's fortunes by two hundred years. He ruthlessly eliminates warlords and reforms the rotten military discipline, then trains the first elite force with improved flintlocks and three-rank volleys. He establishes military farms, improves agricultural tools, and promotes high-yield grains, building up the resources for a northern expedition in the southwestern wilderness. He averts Sun Kewang's rebellion ahead of time and saves loyal ministers such as Qu Shisi and Li Dingguo, ensuring that the legend of defeating two famous kings does not end in failure. He allies with the thirteen eastern Kuizhou families and joins forces with Zheng Chenggong's navy, drives out the Dutch and recovers Taiwan, and opens trade routes through the South Seas to fill the treasury. Three northern armies retake Nanjing, then encircle Yanyun and reclaim the capital, fighting all the way from Guilin back to the Forbidden City and driving the Eight Banners to their ancestral lands in Liaodong. But restoring the dynasty is not enough. He abolishes the garrison system and establishes a standing army, adds natural philosophy and naval studies to the imperial examinations, introduces a land tax reform, builds a nationwide epidemic prevention system, and develops water-powered workshops and ocean routes. He transforms the late Ming's tangled mess of long-standing ills into a new golden age of flourishing firearms, thriving agriculture and commerce, and tribute-bearing nations. From a ruined temple in exile to the imperial court in the Forbidden City, half a lifetime in chaos, half in prosperity. When the System's final reckoning arrives, will he return to the modern era or stay to protect the China he rebuilt with his own hands? An epic of Southern Ming revival, where iron-fisted power struggles intertwine with the everyday lives of the people. Witness how the last emperor of a dying dynasty turns the tide and rebuilds the realm.
