Bright Sword: Create a Torrent of Steel from Hand-Made Flying Thunder Cannons

[No system + build a military industry system from scratch] Kong Jie, an eighth-level fitter, traveled back to the Yunling anti-mopping period with all human weapon information. At the beginning, the independent regiment of Bantian United was in danger. Kong Jie used a shovel to rub the cannon without conscience. The Japanese's crooked handle was difficult to use, and Kong Jie was using his Type 56 light machine gun. Making guns without machine tools is too slow, make them! Silencers, RPGs, rocket launchers,… When an eighth-level fitter has drawings in his hands, I can't even imagine what he can come up with. Brigadier: "From today on, Kong Jie will be my baby." Boss: "Xiao Chen, if you don't let Kong Jie go, I will congratulate you on getting rich."
