In the Arsenal at the Beginning, I Make Equipment for Li Yunlong

Veteran Lin Feng traveled through the mountain city in 1937 and obtained a "universal arsenal system" at the beginning. Others rely on flesh and blood to fight the war, but he relies on technology! As long as you complete "orders" or collect supplies, you can unlock blueprints and upgrade production lines. You can build everything from grenades to tanks and aircraft. While Li Yunlong was still worrying about a few kilograms of grenades, Lin Feng's arsenal had already mass-produced German-made MG42, Tiger tanks, and even jet fighters! Li Yunlong: "Brother Lin, where did you get this new rifle?" Chu Yunfei: "Director Lin, when will your factory's Katyusha be able to support our unit?"
