In the forty-seventh year of Wanli, at the battle of Saerhu, all the elites of the Ming Dynasty were lost. The iron cavalry of the Later Jin Dynasty knocked on the pass, and the war broke out in Liaodong. The factions in the court were raging, Wanli was neglecting his administration, the treasury was empty, and the signs of national subjugation were already apparent. Shen Ce, a graduate student in the History Department of the Military Academy, passed through the body of hundreds of Tieling Guards. It happened that the commander-in-chief wanted to frame the remaining soldiers as deserters and kill them in the name of "camp field ordering". In a desperate situation, he took the military knowledge base in his mind and used his ancestral workshop to improve firearms, gather remnant soldiers, appease the refugees, and build a military stronghold. Use modern tactics to defeat the Eight Banners cavalry, and use thunder to clear out the traitors in the court. He turned the tide before it fell and helped the building to collapse. He vowed to use his passion to reverse the destruction of the remaining Ming Dynasty and recreate the prosperous Ming Dynasty!
