My Gift Lvl 9999 Unlimited Gacha: Backstabbed in a Backwater Dungeon, I'm Out for Revenge!

Long ago, God created nine races, and humans were the weakest and most mocked among them. Light, a young human boy, was lucky enough to be invited to join the "Assembly of the Races," a group made up of all nine races. For a time, he was happy to be part of it-but that happiness didn’t last. His trust was betrayed by his own party members in the vast, monstrous dungeon known as the "Abyss." Left to survive alone at its depths, Light discovers the true power of his ability, "Unlimited Gacha." Now, he must climb out of despair and forge his own empire with the strongest fighters.
