I Opened a Supermarket on the Anti-Japanese Road

I have bound a Wanjie system, which allows me to open the supermarket at any time and at any place. The system said, "Our goal is to earn gold coins." I opened the supermarket business location next to my grandfather's team without any hesitation. The system told me that I was going to lose money. This supermarket has everything you want but everything needs to be exchanged. A shabby cotton jacket was exchanged for a 98K, a pair of fried noodles was exchanged for the latest pistol, and a Japanese head was exchanged for a tank. System: Okay, okay, this is how you play it, right? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
