The red mist descends and the world changes.
When order collapsed and morals declined, Chu Tianhe, who was struggling to survive, accidentally activated the "cell phagocytosis" system in a life-and-death crisis.
By killing zombies, he can gain greater strength and speed; by devouring mutant creatures, he can analyze their genes and gain all kinds of strange abilities.
Claws, carapace, camouflage, regeneration... While others are still fighting for a bite of food, Chu Tianhe has already reached the top of evolution through infinite devouring.
This is a story of a step-by-step evolution from an ordinary person to a "natural disaster" in a doomsday wasteland.
