-(Science fiction apocalypse)+(Wasteland)+(System)+(Double heroines) Lin Mo traveled through a car accident and woke up in an abandoned street. He witnessed a mutant dog devouring a living person. When he was about to die, he awakened the "devouring evolution system" and gained the "primary regeneration" ability by devouring a mutant dog for the first time. A bloody data stream appeared on the system interface, and a mechanical sound prompted "Survival is the first priority."
