Random Climbing in the Late Ming Dynasty

The reason for the demise of the Ming Dynasty was that Chinese history had reached the beginning of the era of heavy industry. The glaciers and weathering in high latitudes acted like centrifuges of liquids and gases, purifying the iron ore in the Northeast. When the Manchu Qing Dynasty obtained Kong Youde's firearms manufacturing technology, they used high-quality iron ore to make better firearms than the Ming army, and gradually gained military superiority. Neither Li Zicheng nor Zhang Xianzhong, who were competing in the Central Plains, would have a chance to dominate the world in the era of heavy industry. Ask the world who is the hero, nobody.
