Shennong in the Late Ming Dynasty: Barefoot Manual to Build the Strongest Iron Army

A doctor of history traveled through time and became a down-and-out scholar in the 17th year of Chongzhen. There is no system, no space, just a cover of "The Barefoot Doctor's Manual" and a head full of historical knowledge. He started from the ruined temple at the foot of Meishan Mountain, took a few children, and fled all the way to the deserted beach by the sea. Boiling salt, fishing, making gunpowder, fighting pirates, collecting refugees, and resisting the Qing army - in eight years, he grew from one person to 5,000 people. From having nothing to having guns, cannons, ships and food. But the real problem has just begun. It is difficult to conquer the world, but it is even harder to dominate the world. Call yourself king or emperor? Centralization or decentralization? Fight or build? What he wants to do is not to become the new emperor. But to build a world that can be turned around without him.
