Unemployed young man Lin An accidentally inherited an abandoned apartment on the outskirts of the city (No. 404 Xingfuli), and was bound to the "weird landlord system" the moment he stepped into the apartment. In order to pay off the huge debt he was carrying, he was forced to start an outrageous career in rent collection. Unlike others who struggled to survive in a strange world, Lin An found that as long as he was in the apartment, he had absolute control over all residents. As a result, he transformed into a ruthless capitalist and turned the horrific stories into beating workers:
Long-haired Sadako was arrested and worked as a 24-hour network administrator (who could also scare netizens who evaded their orders);
The vampire becomes a night shift security guard and works part-time as a blood bank supplier;
The girl with a cracked mouth is forced to do mukbang because she has a big mouth and can eat more.
