The War of Resistance: My Warehouse Leads Directly to 1937

I had just been laid off and rented an abandoned warehouse. Unexpectedly, the back door of the warehouse is actually connected to the battlefield in 1937! When I saw the soldiers using crude Hanyang-made weapons, they were hungry and fighting the Japanese. I'm angry! Lighter, exchange for gold! Instant noodles, exchange for antiques! Penicillin, change to an elite guard! While others were still using telescopes, my drone had already locked onto the Japanese headquarters! While the Japanese were still chasing on horseback, my motorized infantry had already completed the penetration! They called me Mr. Jiang, thinking I was an outsider. Actually I'm just a warehouse manager. They say that I am uncanny and can always predict the enemy's movements. I smiled and said nothing, and opened the history book casually. Jaap: Where did his supplies come from? This is unscientific! Sorry, you are a bit green when it comes to talking about science with the modern industrial system! My goal is: let every soldier eat braised pork and use AK47! Build a business empire that spans two eras, and by the way, fight the Japanese back home!
