Zombie evolution system:
Ordinary zombies: rely on bites to spread the virus, their senses are degraded, and only their appetite remains.
Mutated zombies: Awakening of superpowers due to radiation, alien energy or special genes, such as infinite strength, strong acid body fluids, mimicry camouflage, etc.
Bloodline of the Corpse King: The male protagonist has the exclusive ability to devour high-level life forms (powerful humans, alien creatures, and cosmic races) to fuse their genes and gain evolution, while at the same time controlling the tide of corpses to form a "corpse nest network."
