When she opens her eyes, Su Wanqing finds herself in an apocalypse plagued by sandstorms, where a little hamster recruits her to open a shop. The good news? She's invincible inside the shop, and all the money she earns belongs to her! Starting with selling water and instant noodles, she drives away troublemakers trying to seize her shop and refuses exclusive monopolies. She turns her earnings into new shelves, clean guest rooms, and a sheltered repair workshop. While everyone else just wants to survive another day, she intends to build a business that will last. As the sandstorms grow fiercer, this little shop with its lights still shining gradually becomes a place where people want to stay.
