Little does he know, the Divine Cultivation Tree System has bound itself to him! Every time he defeats an enemy, he can grow the Ultimate Battle Nizer, the Atrocious Form, and even the Mysterious Four Ultras! Using a body double to make a flawless escape, he descends straight into the world of Tiga and begins a crushing, dimension-spanning assault! This time, he won't be a stepping stone that hands out experience. He'll turn the entire universe into his personal ATM! Ancient monsters? Crushed with a single slap! The Kirieloid God? Blasted apart with one swing of his staff! Even the newly awakened Tiga gets pinned to the ground and relentlessly ground into the dirt, learning again and again what true despair feels like! From then on, Earth has a new dark overlord, one who makes all humanity and every monster tremble in fear. Watch Belial, a max-level powerhouse, rampage through the new world, reap the rewards, return to the Land of Light, and make every Ultra Warrior kneel in submission!
