Virus Outbreak: A mysterious virus suddenly breaks out around the world, turning those infected into bloodthirsty monsters. As an ordinary employee of the Biological Research Institute, Cheng Mo witnessed the collapse of civilized society on the first day of the disaster.
Accidental awakening: Cheng Mo was bitten during his escape but did not mutate. Instead, he acquired a "gene plundering system" and was able to acquire special abilities by killing infected people.
Tough choice: Cheng Mo rescues the beleaguered medical student Su Yuqing. The two establish initial trust during their escape. At the same time, Cheng Mo must hide his special abilities.
Ability test: Cheng Mo actively used the system ability for the first time to kill special infected people to obtain "dynamic visual enhancement", which made him realize that he might be the key to human survival.
Doomsday Alliance: Cheng Mo and Su Yuqing decided to cooperate to survive and marched towards the military isolation zone outside the city, and Cheng Mo's system began to show more complex potential functions.
