My Key Connects Both Worlds

Wang Xuan obtained a magical key that can travel between two time and space at will. From then on, there was a magical businessman in Yuzhou City, selling sugar, mirrors, potatoes, corn, arms, flashlights... Every piece of his goods is sought after by thousands of people. No one knows how much money he has. They only know that he is the richest man in the Wei Dynasty. And there is a knight who is good at using sharp weapons in the world. He drives a Harley Drift and puts countless light kung fu masters to shame. Barrett takes my head with one shot from a thousand meters away, and the C4 device makes tall buildings collapse. His name is Wang Xuan, a story about an ordinary person who broke into the world and became a businessman.
