Backstabbed in a Backwater Dungeon: My Trusted Companions Tried to Kill Me, but Thanks to the Gift of an Unlimited Gacha I Got LVL 9999 Friends and Am Out for Revenge on My Former Party Members and the World（Thai Dub）

Light's previous allies turn against him the moment he is expelled from the Concord of the Tribes. Light just escapes this evil act of treachery, only to discover that he is in the most perilous dungeon in the realm—the deepest section of the Abyss! He uses his one magical ability, the Unlimited Gacha, to keep from getting eaten by carnivorous beasts. However, Mei, a stunning Level 9999 warrior dressed as a maid, emerges this time, where it had previously simply generated garbage stuff! After three years, Light has established his own kingdom in this remote dungeon and called forth more stunning Level 9999 fighters who pledge unwavering loyalty to him. Light, who is now a formidable Level 9999 Overlord, intends to rise to the surface and exact revenge on his betrayers one by one!
