Reborn as an Adventurer: I Gain a Skill From Every Monster I Eat

An overworked office drone dies with one regret: he never saw the world. Reborn in a fantasy realm of countless races and floating continents, he grows up an orphan in the slums of Greyhaven — until childhood memories of his old life resurface, and he vows this second chance won't be wasted. At eighteen, he joins the Adventurer Guild and awakens Predator's Feast: eating a monster's flesh can permanently grant its abilities. But power is only a means to an end — freedom to wander, taste, discover, and fill his journal with a world too vast for anyone to fully claim. — Description from novelcodex.org
