Synopsis:
In the third year of the apocalypse, Lu Chen is still one of the lowest-ranking survivors in this dead city. While other Awakened ones command the elements by devouring crystal cores, he risks his life for half a piece of moldy bread. He has no awakened System, and no matter how many zombies he kills, he can't absorb a trace of energy.
Everyone says he's useless.
Until the day an S-rank Corpse King corners him. On the brink of death, he carves open its head with his own hands. Three dark golden crystal cores burn in his palm, and at last, those blood-red words appear on his retina, three years late:
"Devourable gene chain detected. Host aptitude assessment: SSS rank."
"System notification: You aren't unable to awaken. You're just too picky."
From that day on, every zombie in the world becomes part of his menu.
And the mysterious woman who hunted him all the way here from the Eastern Base suddenly stops after he devours his first S-rank crystal core. She narrows her eyes at the mutant energy surging through him. "That Corpse King you ate was my prey for three years. We'll settle this score, slowly."
