Lin Zhiyuan, a top student in psychology, accidentally entered a strange apartment filled with death rules and spatial distortion due to a bizarre lease. Here, the only rule of survival is the "Tenant Code", but behind it lies the intertwined conflict of multiple consciousnesses and purposes. The apartment is not only a prison, but also a hotbed of "apartmentization" transformation, blurring the boundaries between life and death, humans and "rule enforcers". With the unique talent of hyperamnesia, can Lin Zhiyuan unravel the layers of puzzles, use high-IQ games and interactive design to crack the traps of folk suspense, reveal the ultimate truth under the anti-routine setting, and escape this high-dimensional survival game? Every seemingly ordinary rule may lead to irreversible death punishment or unexpected vitality. Welcome to this mysterious building that has been "activated". The lease term has been determined, and life and death are determined by fate.
