In the tenth year after the outbreak of the scarlet virus, civilization fell into ruins, and mankind was struggling to survive under the threat of monsters called "abnormalities." Scavenger Xiao Yanchi lives in the heavily fortified "Safety Zone No. 7". He hides a deadly secret - he is naturally immune to the scarlet virus. This immunity is not a simple resistance, but a strange resonance with the aberrant body. In order to survive, he kept this secret deep in his heart. However, when a sudden disaster struck, his only relative, sister Xiao Zhiyuan, was infected in the chaos. The iron law of "purification" in the safe zone meant that her sister would be executed. In order to save his sister, Xiao Yanchi had no choice but to take her to escape from the last barrier of mankind and break into the wasteland ruled by death and monsters. In his desperate journey to find the legendary "antidote", he not only has to fight against bloodthirsty aberrations and unpredictable human hearts, but also faces the strange power that is awakening in his body and is closely related to this doomsday.
