The End of the World: Supermarket System, Supplying the World

Just when everyone was desperate, Yun Jing descended from the sky with a supermarket system. The goods in the supermarket were of high quality and low price, attracting everyone to grab them. "Boss, do you still have instant noodles?" Yun Jing categorically said: "All products are endless, please don't worry!" A person with superpowers: "Call out all the supplies and spare your life!" The next moment, superpowers appeared in the pile of zombies and became zombie rations. Director of a certain base: "We have requisitioned your supermarket!" Within two days, the entire base disappeared. As a result, everyone was quiet and bought the goods obediently, not daring to make any mistakes again. (Business story, no male protagonist)
