In the Late Ming Dynasty, the Frontier Army, the Small Banner Guaner Firearms Town in Liaodong

[Strengthening the Army with Firearms] [Border Army Counterattack] [Anti-Tatar Guarding the Border] [Liaodong Struggle for Hegemony] [Court of Monarchs and Ministers] In the eighth year of Chongzhen's reign, Liaodong was in ruins. The Hou Jin cavalry rampaged outside the pass. The border troops fled and the fortresses fell one after another. Lin Yan, a special soldier who crossed into the General Banner, was trapped in the dilapidated Lime Kiln Fort, relying only on advanced firearms technology and modern field tactics. Improved paper-shell firecrackers, Yingchoujian robbed four Hongyi heavy cannons; He used more than a hundred remnant soldiers to kill the ambush troops, burned the entire Tatar camp's food and grass, and killed nearly a thousand prisoners in half a year, which shocked the government and the public. The imperial edict came to the capital to call him to face the emperor and be promoted, but he resisted the edict and stayed at the border: the glacier was about to open, the Mongolian army went south, and Liaodong was not at peace, I will never enter the capital! The imperial court made an exception and allocated a thousand men. Each of the four powerful generals led a battalion to build forts and train troops. They guarded the entire Liaodong with firearms all over the sky!
