Shen Yi, the owner of a car repair shop, accidentally traveled to the battlefield of Liaodong in the late Ming Dynasty. He carried with him an unlimited weapons space that could be used to unlock supplies based on the energy of killing enemies, including pistols, grenades, cans, and modern medicines. At that time, the Ming Dynasty's border army was in a state of decay, and the Later Jin Dynasty's iron cavalry was rampaging across the border. Shanxi merchants colluded with Donglin boss Qian Qianyi to smuggle iron materials and gunpowder to support the enemy.
Shen Yi, who was on the battlefield for the first time, relied on advanced weapons to scare away the troops, and recruited desperate low-level veterans such as Qian Er and Zhao Tiezhu to rescue Liu Ruyan, who had a secret life experience. He intercepted a convoy of smuggled enemy goods, but was framed by Jin Yiwei and profiteers. His brother died tragically, his companion was imprisoned, and he became a wanted criminal in the city. When he was desperate, Shen Yi met Sun Chuanting, the former head of the Ministry of War who was wronged and demoted, and a group of veterans who were down and out. Armed with advanced weapons and proficient in modern tactics, he decided not to hold back any longer.
Based on the dilapidated beacon tower, Shen Yi used cans to win people's hearts and trained troops with modern firearms. He dealt with hundreds of corrupt households, ruthless bosses, smuggling Shanxi merchants and Donglin power traitors, while rescuing captured companions, cutting off the enemy's profit chain, and cracking the tampered Liaodong border defense plot. On the inside, he has to clean up the traitors in the court and the worms in the army, and on the outside, he has to resist the menacing Houjin cavalry. Shen Yi, who has an unlimited arsenal in his hands, is determined to tear apart the many shady curtains of the troubled times in the late Ming Dynasty, and find a way to protect the people and fight against the wolves in the devastated land of Liaodong.
