Evolve by Devour: The Ultimate Dragon

Yale Carter transmigrates to a beast-contracting world, and becomes a mangy F-rank trash beast, despised by school belle Quella Lynn and ridiculed by everyone. On the brink of death, he activates the devouring evolution system. Starting with the Shadow Wolf, he devours his way forward, transforming from snake to serpent, and ultimately evolving into a world-shaking creation dragon. Facing the doomsday beast tides sweeping the globe and powerful enemies from other worlds, he joins forces with humanity, fighting through blood and fire, devouring gods, and stepping onto the path toward ultimate evolution.
