The doomsday has come, the world has been reduced to ruins, and zombies and mutated creatures are rampant. At the critical moment of life and death, college student Lin Yuan was betrayed by his former friends and pushed into a group of corpses, but unexpectedly awakened the mysterious ability of "Swallowing Evolution".
By devouring the flesh and blood of zombies and mutated creatures, he can obtain gene points, continuously strengthen himself, and even plunder the opponent's abilities.
From the power of ordinary zombies, to the speed of speed walkers, to the defense of giant zombies... Lin Yuan embarked on a never-ending road of devouring evolution in life and death fights.
In this cruel new world, what he has to do is not only to survive, but also to stand at the top of the food chain and become the master of the doomsday.
