When I Traveled Through Time, I Opened a Convenience Store in Liangshan

Zhou Heping's convenience store has been open for half a year, but it is not operating well and is about to close. But that night, when he was about to jump into the river, he was selected by the system. The system asked him to travel through the Water Margin and Liangshan Mountains, and then asked him to open a convenience store there. Since there is a surplus of materials in modern society, then the materials should be transported to ancient society. Earn the gold bars and silver of the ancients.
