My Grocery Store, Think of It as a Wishing Fountain

All worlds open, only my grocery store. Chenba is bound to the Wanjie Grocery Store System and serves as the top trading power in the world, but it has only one ultimate dream - to have enough food and endless snacks. The system rules are strict and the outing time is seriously insufficient. He is not greedy for all kinds of opportunities, he only covets the fireworks and delicacies of the world. While others practice cultivation to seek immortality, he opens a shop to stock up on snacks. While others compete for luck, he only asks his exclusive clerk to run errands and bring food. The red door leads to the present world, and the blue door leads to all realms. This store sells everything, but the store manager only wants to make a living and dominate the world. According to grocery store customers, the staff in the grocery store are very friendly, but their eyes often glow green, and they don't know why.
