In the third year of Hongwu's reign, the social animal Lin Yan stepped on the air and fell into a pile of refugees in Haozhou.
He originally wanted to stay alive, but he used modern first aid knowledge to save the emperor's grandson Zhu Xiongying, and was dragged into the power center of the Ming Dynasty as a "folk strange".
By improving agricultural tools and making simple fertilizers, he filled the warehouses of farmers in Jinling; by building telescopes and modifying gunpowder, he helped the Ming army beat the Northern Yuan Dynasty to the point where they could not find the north; by playing public opinion wars and making bamboo recorders, he dismantled the conspiracy of the poisoned queen Lu.
Zhu Biao bowed to him, Empress Ma loved him as a younger generation, Zhu Yuanzhang loved and feared him, and even the young Xiongying clung to him and called him "Uncle Lin".
It's just that this modern-day complainer always makes weird remarks about "KPI" and "check-in" in the court, which scares the veterans of the Hongwu Dynasty.
Watch an ordinary time traveler use practical knowledge to stir up the Hongwu situation, protect Zhu Biao and his son, and turn the Ming Dynasty, which focused on agriculture and suppressed commerce, into a prosperous Jianwen era of prosperous maritime trade!
