Shuttle Between Two Worlds: the Fire Machine Is Replaced by the Beast-Eared Girl at the Beginning

Bai Mo never imagined that one day he would be able to freely travel between reality and a game world called "Primitive Tribe". What's even more outrageous is that items from both worlds can be brought back freely! Then, everything changed. A two-dollar lighter was an artifact that could make fire out of thin air among primitive tribes. Three yuan a pack of refined salt can drive the entire tribe crazy. A stainless steel kitchen knife costing more than ten yuan is a peerless weapon that can cut iron like clay! And at the beginning, he exchanged his lighter for a beautiful and alluring girl with animal ears! ........ Relying on the huge price difference between the two worlds, Bai Mo was reselling supplies and making crazy money while developing his tribe and bringing the seeds of modern civilization into the wild world. Many years later. When a huge primitive empire sprang up in another world, and when Bai Mo's industries spread all over the real world, someone finally couldn't help but ask him: "Mr. Bai, how did you start from scratch and get to where you are today?" Bai Mo thought for a while, looked at the beast-eared girl nestled in his arms and smiled. "Probably..." "It started with a two-dollar lighter."
