Three years after the "Great Annihilation", the world became a hell on earth. Ah Feng, who once insisted on kindness, led the survivors to survive in the ruins, but was repeatedly slaughtered by scavengers. When his companion died tragically while protecting others, he finally understood that kindness could not buy life. Blood debt must be paid with blood. The former guardian put down his bottom line, grasped the blood-stained dagger, and used killing as the blade. He opened a bloody road to the safe zone in the desperate apocalypse, vowing to fight violence with violence and clean up the filth in the world.
