I recommend the book " Farming in the Chaos of War ". The protagonist brought the cheat device to a special era where the economy was declining and productivity was lagging behind. He lived a life of men farming and women weaving. The entire village was a soldier. Farming, paying taxes, serving in the army, exorbitant taxes, miscellaneous taxes... It turned out that farmers had these additional items. The Liu family of three had led a farming life of men plowing and women weaving. They planted mulberry trees, raised silkworms, weaved cloth, and farmed all year round. They arranged agricultural production according to the seasons. Famine, bandits, military disasters, and escape…It was not easy to farm in peace.
