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

Expelled from the Concord of the Tribes, Light gets betrayed by his closest allies and then is left all alone for dead. He barely escaped from there and got into the deepest dungeon known as the Abyss. With monstrous beats closing in his surroundings, he only depended on his magical power of Unlimited Gacha. 

This magical power was useless and produced only junk now it grants him Mei, a breathtaking level 9999 maid warrior. Three years later, Lights defeated every monster and ruled over the Abyss with his faithful army of Summons. Now a level 9999 overlord himself, he ascends to the surface and takes revenge on the aliens who betrayed him.
