Xiao Zhang, a young clerk, worked the night shift alone, and it was windy and rainy outside the convenience store. From the surveillance camera, he saw a dark figure flashing next to the shelf in the corner. I thought I was mistaken, but then the product fell down on its own and the refrigerator door opened and closed automatically. He checked in fear, only to find that there was a blurry figure behind him in the surveillance screen, and in the rain curtain outside the store, there seemed to be a pair of eyes staring at him, and a terrifying adventure in the convenience store began.
