Liangjian: I'll Take Li Yunlong to Rub Italian Cannon

Time Travel + War of Resistance Beacon + Military Industry + Bright Sword + Hard Core Technology Zhang Mingyong, a doctor of chemistry, traveled through the battlefield of the Anti-Japanese War and saw the bloody battle of Li Jiapo when he opened his eyes. Li Yunlong grabbed his collar: "Are you a fucking Japanese spy?" Zhang Mingyong looked at the misfire grenades scattered all over the mountains and plains, pushed up his glasses: "Captain Li, give me a pot, I can make the Italian artillery explode in the border area." From home-made saltpeter to seamless gun steel, from gunpowder improvement to the implementation of the production line. When the first "Jin-made" mortar roared and tore apart the Japanese positions, Li Yunlong clapped his legs and laughed wildly: "This guy is better than his wife!" On Zhang Mingyong's laboratory blackboard, there is a periodic table of elements drawn leading to the future - this is just the beginning of a dimensionality reduction attack.
