I Owe the System a Jar at the Beginning

Bai Mu accidentally bound the can-opening system of all things, but he started with 10,000 earthen cans and ended up eating dirt. He was forced to set up a stall and trick others into opening cans to earn reputation and gradually upgrade the cans and space. From the streets to the global spotlight, countless powerful people spend huge sums of money just for a jar in his hand. Eventually, he became a mysterious jar merchant connecting all realms, and the legend of jar opening spread throughout the world.
