[Simulation + Dark + Non-Human + No Female Protagonist] Once an ordinary human, Oliver awakens in a dark world as the lowest and weakest monster: a goblin. Immediately, he falls victim to human adventurers and is ruthlessly killed. But death is not the end for him. With his demise, he activates the Life Simulation System, an ability that allows him to replay and manipulate his life’s events, learning from each failure to make better decisions. Moreover, as a goblin, he receives the rare divine blessing bestowed only on his kind, offering him opportunities to evolve into powerful forms. Through constant trial and error, Oliver begins to reshape his destiny. Every simulation brings new knowledge, whether in strategic battles, devouring powerful creatures to absorb their strength, or evolving into advanced goblin types. From his humble beginnings, Oliver relentlessly ascends, using his cunning and the system to outsmart enemies and grow stronger with each iteration. As Oliver evolves into fearsome forms—first a Goblin Warrior, then higher-tier beings—his ambition becomes clear: to conquer the world that once sought to exterminate him. Along the way, once-invincible entities, such as the revered Sword Saintess, the Mother of Dragons, and even angelic deities who once looked down on goblins, find themselves bowing before him. With no female lead or conventional protagonist, this dark, non-human narrative explores Oliver's rise from obscurity and his quest to become a figure of ultimate power in a brutal, unforgiving world, defying all odds and expectations.
