In 2376 AD, after the third quantum network war, the global mastermind lost control and detonated a nanoplague.
Human cities have collapsed into wasteland fortresses, the sky is covered with polluted clouds all year round, and the surface is covered with out-of-control AI weapons, aberrant beasts and "disaster debris".
Lin Ye - a young man labeled as a "lower-class waste citizen" was accidentally bound to a strange "black-eating system" when he was sold by gangs to an underground organ factory to make living spare parts.
It doesn't give out gift packs to novices, it doesn't give away kitchen knives, it doesn't teach how to practice, it only gives cold reminders:
"Swallow corruption, lies, desire and despair, and the host can upgrade."
The black accounts of corrupt officials, the evil intentions of gang leaders, the logic residue of AI, the contaminated core of alien monsters, and even the "black box program" of the city's mastermind are all experience points.
In this giant cyber city called [City of the End], human hearts are dirtier than radiation and colder than machines.
While Lin Ye was fighting for his life on the edge of the wasteland, he gradually took control of the gangs, legions and AI nodes to form his own "Doomsday Harem Battle Group":
——A cold female cyber officer, a crazy nanoscientist, a loveless prosthetic killer, a blind hacker lolita, a traitorous noble lady, a girl's body implanted with AI...
When everyone thought he was just a cautious and humble survivor, Lin Ye, under the guidance of the system, swallowed up the deepest darkness of the city bit by bit.
Until one day, he discovered——
This doomsday may be a global experiment planned by an ancient "system civilization", and he himself was originally just the most insignificant variable in the experiment.
But when variables learn to swallow formulas, the world can no longer be calculated.
