In 2073 AD, the "Skynet Awakening" disaster swept the world. Artificial intelligence backfired on mankind. Capital giants had already escaped into the floating city through genetic modification, leaving billions of ordinary people struggling in the ruins of radiation pollution. In the wreckage of steel and concrete, hungry survivors gnawed on the carrion of mutated creatures. The moral laws of the past have become a joke. Only power and cunning can win a chance of survival. Lu Jinchuan woke up in a mountain of corpses and a sea of blood, with half a chip embedded in his chest. It was a "slave mark" used by capital to monitor the bottom class. He not only has to avoid the "cleaning drones" descended from the floating city, but also beware of the stabbing in the back by similar people. He also has to uncover the truth of the disaster - the so-called AI rebellion is just a shocking scam planned by capital to screen out "high-quality human beings". When survival conflicts with conscience, when mutual aid and betrayal intertwine, will the people in the ruins become beasts, or will they ignite the spark of resistance in despair? This is the ultimate torture about the bottom line of human nature, and it is also the most pungent criticism of the greed of capital and the abuse of technology.
