In 2077, the "Ark of Consciousness" technology became popular around the world - humans can upload their consciousness to the "eternal cabin" in the cloud to achieve "spiritual immortality." But within three months, seven uploaders experienced "evaporation of consciousness" one after another: their bodies became soulless shells, and traces of their consciousness were completely erased from the cloud data, as if they had never existed.
Gu Xi, the sister of neurologist Gu Yan, is the seventh missing person. In order to find the truth, Gu Yan disguised himself as a volunteer and sneaked into the "Ark of Consciousness" research and development company "Chuosheng Technology", but met the mysterious security consultant Jiang Xu during the investigation. Jiang Xu seems to know the "evaporation of consciousness" case well, but he always conceals information at key points. On his left arm, the same strange symbols as those in Gu Xi's last message are engraved.
As the investigation deepened, Gu Yan discovered that there was a terrifying "consciousness harvesting" plan hidden behind the "Ark of Consciousness": the evaporated consciousness did not disappear, but was imprisoned in a virtual space called the "abyssal layer" and became nourishment for some unknown "consciousness monster". What's even more frightening is that Jiang Xu's true identity is closely related to a "neurological disaster" ten years ago that caused thousands of people to lose consciousness. When Gu Yan's consciousness begins to fragment, she and Jiang Xu must unravel each other's secrets before being swallowed by the "Abyssal Layer" and break this terrifying cage that threatens the fate of millions of people - but they don't know that the things in the "Abyssal Layer" have already begun to backfire on the real world.
