Shang Tian accidentally traveled through a parallel world with no system, no plug-ins, and no adventures. When he was penniless and desperate, he accidentally broke into the time and space building that connects different time and space. There are residents from different eras living in this building, and he accidentally became the manager. From then on, his life was completely filled with this group of neighbors across time and space: today he has to persuade ancient poets not to fight for the Internet with counselors, and tomorrow he has to stop martial arts masters from using the elevator to practice Qing Kung Fu. He is surrounded by all kinds of weird situations every day, and a hilarious career as an administrator begins.
