Programmer Su Chen is bound to the "Fear Safe House" system and is forced to travel through a world of strange rules and weirdness. His mission is not to escape, but to build an absolutely safe hut in the center of terror in each world to shelter the creatures chased by fear. Collect fear and strengthen himself. When countless weird things roared outside his door, Su Chen sat on the soft sofa in the house, drank hot tea, smiled at the door and said: "Don't worry, line up and come one by one." This book tells the story of how he used fear to create safety in various worlds and used weirdness as fuel.
