At the Beginning of Diaoyu City, I Made Firearms and Swept Through Mongolia.

Chen Du, a graduate student in the Department of History, wakes up and travels back to the late Southern Song Dynasty and becomes Zhao Boheng, a fourteen-year-old clan boy in Diaoyu City. At this time, Chongqing has been defeated, Zhang Jue was captured, the isolated city was besieged, and food and support were exhausted. The history books have determined that in the first month of next year, Kaicheng will surrender. With military knowledge that transcends the times, he will never let this iron-blooded lone city that has endured for thirty-six years come to an end. Make gunpowder, forge cannons, train new musket troops, and change the defense line of the city. One cannon blasted the Meng Yuan cavalry to pieces, a volley of firecrackers shocked all directions, firearms replaced magic weapons, and knowledge reversed the universe. The Mongolian and Yuan armies are approaching? Just in time to use it as a sacrificial cannon! Survive in a desperate situation in an isolated city? Directly launch a counterattack! Let's watch the young man rebuild the iron-blooded mountains and rivers on his own. Taking Diaoyu City as the starting point, use firearms to sweep across the world, regain the Song Dynasty, and go straight to Dadu! ——The beginning is a desperate situation, and firearms determine the situation!
