In AD 2491, the universe is folding. Every irregular period, certain dimensional areas will be compressed and collapsed, and all matter and energy in them will be turned into "dimensional debris" - a strange substance between existence and non-existence. Scavengers are the most dangerous profession of this era. They go deep into the folding area and salvage valuable information fragments and technological heritage from the wreckage. During a routine mission, low-level scavenger Shen Jibai accidentally obtained an abnormal piece of debris from the "zero dimension". Hidden in the wreckage is a secret that is enough to subvert human cognition - dimensional folding is not the natural evolution of the universe, but the "information harvesting" of the lower-dimensional world by higher-dimensional beings. The target of the next large-scale folding is precisely the three-dimensional space where humans live. Shen Jibai was forced to get involved in the game between the Scavengers Union, the Dimension Research Institute and the mysterious Fold People. His father died in the Fold years ago, leaving clues that point to a possible plan to counter the Harvest. With little time left, Shen Jibai must piece together the answer to human survival from the scattered wreckage before the dimension is crushed.
