Anti-Japanese War: My Understanding Is Incredible, I Started Rubbing Katyusha with My Hands

Lin Feng traveled through the Anti-Japanese War and became an ordinary soldier in the logistics transportation team, awakening his heaven-defying talent! No guns or cannons? I can make it just by looking at it! You watched the Sanba Gai, suddenly understood the principles of firearms, and made a Garand semi-automatic rifle! You dismantled Japanese dumb bombs, analyzed the composition of gunpowder, and developed thermobaric bombs and cloud explosive bombs! You looked at the abandoned railway tracks, understood the mechanical structure, and built a Katyusha rocket launcher cluster! Li Yunlong: "I also want to keep a low profile, but all Lin Feng gave me are fully automatic firearms. It's hard for me not to make a fortune!" Boss: "I asked you to repair the gun, and you created a mechanized heavy armored army for me?" From hand-made rifles to Dongfeng missiles, from indigenous steelmaking to the establishment of the Northern Industrial Zone. When the 700,000 Kwantung Army moved south, they were completely shattered when they saw the sky full of jet fighters and the rising mushroom clouds. Lin Feng: "I'm really just a logistics guy. Is it reasonable to wipe out an entire island?" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
