Anti-Japanese War: Start with a German Weapons Arsenal

When he woke up in a war-torn era, Lin Su just wanted to quietly make some weapons in the arsenal to protect the country and the people. But the strength doesn't allow it! Friendly Army: "Commander Lin, where did you get these 88 guns? Masturbating is like shooting birds!" Lin Su: "It's passed down from our ancestors, it's been passed down from our ancestors." Japanese Army: "Report to the Division Commander! We were bombed by a large number of enemy aircraft!" Lin Su: "Don't talk nonsense, I modified it with a tractor." Okamura Neiji (lifting the table): "Enough! Baga! This unit has more firepower than one of our front troops? How can we fight this battle?!" Lin Su spread his hands and looked innocent: "I'm just a patriot who knows a little bit about science. As for my troops... They are just ordinary Chinese soldiers, but they are only a little better equipped."
