My Interdimensional Supermarket

Ian Zhang's supermarket opens a cross-dimensional branch. One step takes you to the Jin Dynasty imperial city, the next back to a modern wholesale market. A pack of instant noodles makes a prince break down, and an iced drink exchanges for a priceless Dragon-patterned Jade Pendant. While ancient nobles fight over dirty ice, he achieves 'ice freedom' with an ice maker. A one-yuan ballpoint pen brings Jin Dynasty intellectuals to tears.
