Zombie Apocalypse: Infinite Evolution Through Core Devouring

The apocalypse arrived. Zombies ran rampant, and people with special abilities lived or died according to their rank.

From F to SSS, the nine-rung ladder meant the weak had to watch the strong even to catch their breath.

Lin Ye had a System, but after a skirmish left his mind badly damaged, his powers were nearly crippled, and he was reduced to a weak, unstable B-rank.

He couldn't unleash devastating attacks or recklessly exploit cheats. Every time he used a skill, it drained him, and a single burst of power left him exhausted.

While everyone else stuck to a single ability, he was determined to take a path of madness:

with martial arts as his foundation and supernatural powers as his blade, he would unite magic and martial arts.
