They Made Humans Pets. He Made Them Prey!

By 3055 humans are livestock and slaves. The mutant beasts and the other races eat them, work them and use them for entertainment, and the species is running out of time. Liam Blaze grows up in the slums with nothing to distinguish him, and he awakens a system that lets him hunt beasts and consume them, taking their power each time. They put him on an operating table to have him neutered, and he got off it. They threw him into the Drakari Tower, and he climbed it, killing his way up. He eats gods and demons and absorbs what they had. Every humiliation done to his people he returns a hundred times over. With each kill humanity gains ground.
