Hidden behind a glass showcase in a corner of the city is a magical supermarket that can connect all worlds. Lin Xiaocha and her "Human Encyclopedia" partner Gu Chen run this small shop that specializes in collecting rare treasures - from heart-reflecting beads formed from the tears of a deep-sea mermaid to mirror fragments that can reflect past lives, every item has a story that spans time and space. When fishermen from the tidal plane come to the door with smooth-grained "tide shells", and when messengers from the cloud plane come carrying marshmallows that make snow fall on their backs, this supermarket becomes a meeting point for the debris of the universe.
