The Evolution of the Weakest Ghoul

Ronan had already died once. After transmigrating into a world of magic and monsters, he believed fate had finally given him a second chance. Then the Abyss invaded. As humanity awakened powerful Traits to fight back, Ronan awakened... nothing. He died as just another forgotten casualty. But death wasn't the end. He opened his eyes as the weakest of all Abyssal Creatures—a Ghoul. Surrounded by monsters that saw him as nothing more than prey, the only thing keeping him alive was a mysterious ability that allowed him to extract and evolve the Core Traits of the races he killed. Ghouls. Vampires. Demons. Dragons. Angels. Gods. In a world where every race is bound by its own limits, Ronan will carve out an evolution that has never existed before. After all... If he can survive today, he can become stronger tomorrow. — Description from novelcodex.org
