When the high-energy particle storm swept across the earth like a sky collapse, all life became experimental subjects in the genetic furnace. The military base "Ark" has become the last bastion of mankind. Soldier Lu Chen clenched the butt of his gun and stared at the twisted figures in the surveillance camera - those former comrades were growing scales, and in the laboratory, scientist Su Rui was recording the 73rd distortion mode of particles on DNA with trembling hands. Mutations spread quietly within the steel walls. Some people turned into monsters that devoured their own kind, and some awakened incredible abilities. Lu Chen had to hold on to the physical defense line, and Su Rui had to crack the particle code. When the base's oxygen supply system was chewed out by mutants, and when the research data pointed to the wisdom signal behind the storm, the man and woman with conflicting positions realized that the real enemy was never the out-of-control genes, but the shaky trust of mankind in the apocalypse.
