Under the neon lights of modern cities, strange rumors that no one can confirm are circulating. The elevator stops at a non-existent floor at midnight, the sound of chewing bones comes from the sewer, and unfamiliar faces are reflected in the glass windows of high-rise buildings. Lu Li knew that these were all true. His family has been dealing with the "filth" hiding in the shadows of the city for generations, driving them back into darkness.

When Lu Li was repairing an unknown ancient book, he found an old photo in the book, which was actually his sister Lu Xiaoyun who disappeared ten years ago. "Don't look for me" was written in blood on the back of the photo. That night, my sister's singing came from the library's underground stacks. Lu Li walked in carrying an ancestral bronze lantern, and the flames of the lantern illuminated the depths of the library. There was no sister there, just a girl in a blood-stained school uniform, squatting with her back to him. The girl slowly turned her head. Her entire face had no facial features, only a piece of wriggling black text. She grinned, and the words dripped down, forming a sentence on the ground. Brother, you are finally here.
