At the end of the Ming Dynasty, Bing Wang rubbed the core with his hands to flatten it.
My name is Qin Ziying, the king of Chinese soldiers and weapons maniac in the 21st century, who traveled through the late Ming Dynasty and became a dying soldier. The hungry people exchanged their sons for food, the frontier troops were as thin as firewood, and Chongzhen was still extorting pay and killing people. I went into the mountains in anger: Give me three months to build a standardized flintlock production line with my bare hands! Just when I trained the first modern firearms battalion and prepared to bring peace to the troubled times. However, the imperial guards from the capital rushed over overnight to report in panic: "Your Majesty is surrounded by King Chuang at Meishan. The situation is critical. Please help him quickly!" I sneered and picked up my self-developed nuclear Ping-1 rifle: "Tell Chongzhen that I have a new emperor here who I want to talk to."
