In 2038 AD, Pengcheng was folded into three levels: the smooth and cold upper city, the noisy and crowded lower city, and the underground where the sun never shines all year round. The H virus released in the "Tashan Incident" ten years ago did not kill anyone, but it changed the human race - some people awakened to the ninth level of supernatural power, some people enhanced their bodies with technology and became weapons, and more people became the targets of "screening".
Legend has it that the H virus is a "civilization filter" launched by higher civilizations, leaving only seeds worthy of the new world.
One day, the young Wang Wang from the lower city was born with a scar under his left collarbone. It was a key that could reversely close the filter. A viral doomsday prophecy video, a crazy saying "There is something ringing in your body", and an unsent receipt of his father's medical examination dragged him into the prelude to collapse. When the city becomes a hunting ground within twelve hours, when the "Parliament of Evolution" and the "Parliament of Survival" draw swords for the destination of civilization, he must find out: Are he a defective product of the screening, or a person who ends the screening?
