Magic, monsters, and powerful beings dominate the land, with ruthless forces waging war for supremacy. And Ricky? He possesses a terrifying ability—he can drain lifespan from any living creature and use it to evolve.A single bite can grant him hours. A feast?..... Years!!Now, in a forest filled with predators and beside a village on the brink of destruction, Ricky must climb the evolutionary ladder—from insignificant pest to a calamity that could devour the world itself.But when his first real meal triggers a mass sacrifice, the world mistakes him for a rising Demon Lord. Bounties are placed on his head. Armies march to hunt him down. And lurking in the shadows, a forbidden power calls to him, promising a path beyond mere survival—one that could reshape reality itself.In a world where everything is prey to something greater, something horrendous… he will rise to become the apex.
