If Nanming Defended the Yangtze River

A man from science and engineering travels to Chengnan, the deposed king of the Ming Dynasty, and uses scientific thinking to rebuild the mountains and rivers and start the Eastern Industrial Revolution!​​ ​​Desperate start​​ In the fourteenth year of Chongzhen's reign, Luoyang City was destroyed. The 300-pound good-for-nothing King Zhu Yousong was paralyzed on the escape carriage, his wounds festering, and behind him were the pursuers of the invading army. And the soul of the modern engineer awakens at this moment—— "This body can't live for three days? Will the Qing army enter the Pass in four years? Only one year left in the Southern Ming Dynasty?"​​ ​​Hardcore Breaking​​ A scalpel cuts through carrion, a thermometer improves the blast furnace. He sees Jiangnan not as a desolate mountain, but as an undeveloped industrial experimental zone: Saltpeter ore + sulfur = granular black powder assembly line Waterwheel forging hammer + coke crucible = standardized production of flintlock barrels Rotten catch + quicklime = local chemical fertilizer increases yield three times ​​When the Donglin Party was fighting for power, he was recording data in the laboratory; when Xungui was occupying the land, his ship was carrying potato seeds back to America.​​ ​​Changing fate against heaven​​ In 1645, when Duduo drank from his horse in the Yangtze River, what he saw was a line of defense that subverted cognition: Yangzhou City Wall: Flowering bombs smashed the ladder like a thunderstorm Guazhou Water Village: Chain bombs spun and tore apart a giant Qing ship New Army Formation: Three-stage flintlock attack crushed the Eight Banners cavalry "Your Majesty, the range of the Ming army's firearms... Is three times that of ours!"​​ ​​
