Shen Ye is bound to the "Order Maintenance" system, and her mission is to go to various out-of-control rule-based worlds and play the most basic security role. While other chosen ones are struggling to survive in ghost stories, he has to clock in and patrol on time, issue employee rules to the cracked girl, define the office area for Bixian, and make attendance sheets for the red ghost. Until one day, he discovered that these strange worlds were connected to each other, and the original source was waiting for him to close the last door.
