A sudden and strange epidemic, like a raging black tide, instantly swallowed up the originally prosperous and orderly world. The infected person's body twisted and screamed in pain. There seemed to be countless insects squirming under the skin, and his eyes were full of madness and chaos - it was the despair after the spirit was polluted.
The city has been reduced to ruins, the streets are filled with the smell of putrid stench and despair, blood-colored mist floats among the ruins, and every inch of air is telling the lament of doomsday. In this desperate situation, Shen Che, who was once a technician in a biogenetic laboratory, became a special "epidemic chaser" in the darkness. Not only is he good at using self-made equipment to detect the mutation trajectory of the epidemic virus, he also has the rare ability of "epidemic resonance": by touching the remaining traces of infected people, he can vaguely perceive the direction of the spread of the epidemic, and even avoid deadly traps hidden in the epidemic fog.
Some say he is paranoid, and dares to sneak into a research institute occupied by "abnormals" alone in order to test a hypothesis about the mutation of the epidemic virus; others believe that he is reliable. Even if supplies are exhausted and his teammates are shaken, he can still find a way out with his keen perception of the epidemic virus, and has never given up on tracking down "a batch of experimental samples that suddenly disappeared before the outbreak of the epidemic." In this era rewritten by the epidemic, hope is like a candle in the wind, and human nature is struggling between good and evil. Shen Che led a group of survivors with their own specialties, while avoiding the "abnormals" who evolved special abilities due to the epidemic, while tracking down the "Ashes Organization" that secretly controlled the spread of the epidemic - the marks they left were actually related to the unfinished experiments that Shen Che had participated in.
