It started with a bad start, and all the teammates were in trouble!
Lin Fu, a master of modern military industry, transformed into an auxiliary soldier in Liaodong of the Ming Dynasty who was so hungry that he chewed tree bark. All that was left of his possessions was a polished brass pot.
Japanese pirates are attacking? When he swung the pot, he used a "cooking squad's art of war": using blunderbuss and laying potato mines, so that the enemy would say he didn't have martial ethics! I wanted to make inventions safely, but I was dragged into a dead end in the court. The idiot boss in the Shenji Camp clings to the ancestral system, and the great eunuch Feng Bao's sword has reached his back; after Liaodong took office, the border wall collapsed, the army's pay was empty, Nurhaci's 50,000 cavalry pressed into the border, and the court's war order and the false accusation of "collaboration with the enemy" were sent at the same time...
In a desperate situation, Lin Fu polished the copper pot and smiled: "Since you can't win with your rules, use my rules to rewrite Liaodong!"
So——
Farming and stocking up on potatoes and trading cards with each other allowed the Eight Banners cavalry to sacrifice for food; hiding messages in medicine pouches to spread spy networks, inserting eyes and ears directly in front of the enemy chief's tent; casting cannons in melting pots to calculate ballistics, and technology to crush the hegemony of cavalry and shooting!
But when Saerhu was defeated, Chongzhen hanged himself, and the Ming Dynasty was about to die...
Everyone thought it was over. Only Lin Fu stood on the ruins of Ningyuan Fort, facing Hong Chengchou's persuasion to surrender and tens of thousands of Qing troops. He put on the official robe of the Ming Dynasty and raised the copper pot covered with arrow marks: "The dynasty will perish, but the soul of China will never be destroyed. This pot has protected food and blocked arrows. Today, use it to defend China... To the last moment!"
This is the dimensionality reduction attack of hard-core science and engineering thinking on the feudal era. See how a pot stirred up the storms of the late Ming Dynasty. Even if the mountains and rivers are broken, we must let the fire of civilization illuminate the future!
