Rules for Building No. 7, Yongan Lane

On the city map, Building 7 in Yong'anli was reduced to rubble ten years ago. But in the midnight fog, it wakes every night. To find his missing younger sister, former forensic examiner Xu Ce signs a contract to patrol the building on the night shift. In the security office, the bloodstained black rules clash with alluring red words written in blood. Remember: don't count the shadows in the hallway, and whatever you do, don't look back. Those who break the rules become bricks made of flesh and bone.
