Lin Mo scores zero on the Awakening Test and is branded a failure. As he lies on the brink of death, the lingering soul of a future Martial Saint arrives: “I'll teach you to devour strange beasts.” From then on, with his eyes closed he's human, and when he opens them he's a beast. He can smell lies, hear people's thoughts, and see souls. When the Abyssal Lord begins harvesting all living beings, the world finally realizes that the creature they feared as a monster has been protecting them from the darkness all along.
