In the 2.5Th century, human "reality" is redefined by the three-layered world. The upper level is the "Sky City", where the elites enjoy the eternal tranquility of the post-material era under the perfect care of the AI "Gaia"; the middle level is the "Relay City", where billions of citizens are wrapped in a hive society constructed of data and credit points, providing power for the operation of the entire world; and the bottom level is the forgotten "settlement zone", where there are only rust, acid rain and "remnant people" scavenging in the ruins.
Chu He, a remnant struggling to survive in the subsidence zone, managed to survive with his cleverness and optimism engraved in his bones. His biggest dream is to save enough credit points to buy a water purifier that can filter heavy metals in acid rain.
Until that day, he accidentally picked up a strange crystal that could not be recognized by any system in the wreckage of a "Messenger" that crashed in Sky City.
From that moment on, the world in Chu He's eyes began to "drop frames." He can see the gleaming "cracks" at the edge of the real world, and can hear the weird murmurs deep in the data stream. He was targeted by the powerful corporate giant "Omniscient Group" and the mysterious regulator "Silent Order" at the same time, and was forced to embark on a crazy escape.
In this pursuit that spans the physical world and the information dimension, Chu-He will get to know a group of "deviants" who have also been abandoned by the world. Together, they will pry open a corner of this seemingly perfect "cocoon city" and spy on the ultimate truth about the survival of human civilization that has been concealed by the elite and super AI.
