Anti-Japanese War: Bring Out the Submachine Gun at the Beginning and Kill the Japanese

[Anti-Japanese War] [Military Industry] [Gun Making] [Guerrilla Warfare] [Travel] [System] [Explosive] [Not the Holy Mother] [Taihang] [Iron-Blooded Strong Army] Lin Yan, a modern military engineer, traveled through the war-torn years of the Anti-Japanese War. He was broke and broke, but he took the military industrial space and manufacturing system with him. No gun? Make flower mechanisms by hand, modify rifles, and make sniper rifles. No cannon? Build mortars, grenades, and directional mines, and bury them all over Taihang. No soldiers? Collect ruthless bandits, unite martyrs, build an iron-blooded detachment, and raise an elite anti-Japanese force from scratch. A front-line ambush, annihilation of the Japanese squad with zero casualties, road bombing, coal transportation interruption, counter-mopping up... When the Japanese come, let him be buried in the Taihang Mountains. The gun towers were blown up, the strongholds were demolished, the roads were destroyed, and the Japanese cried. In this life, we will not be aggrieved, uncompromising, or attached, and rely on our military industry to kill through North China and sweep away the Japanese invaders!
