Bonnie's uncle is a strange eccentric who runs an old library by himself. There are three or two guests coming and going a day, but the library has never closed down. The uncle was dressed in rags, but he was unwilling to close the library from the beginning to the end. His mother once asked his brother why he was so obsessed with a library. Is there any secret inside? At midnight during the Mid-Autumn Festival, Bonnie and her friend Mary went to the library together. To be honest, she had known her uncle for a long time, but she had never been to this library. Her mother said the library was weird and wouldn't let her go near it, but she couldn't bear her curiosity and finally chose to come to the library on this day. The door to the library was still open at night. Bonnie and Mary boldly went inside. A mirror in the depth made them curious. They heard a "pop" sound and the lights turned on. But they are not in the library, but in another adversity. Where is this place? What will happen to them? What is waiting for them ahead? What's my uncle's secret again? They explored uneasily...
