My Light Magic Is Outrageously Overpowered

Song Jie, a loyal fan of All-Time Mage, thought transmigrating into its world was a dream come true. Until he awakened the weakest element: Light magic. Mocked and dismissed as useless, his excitement quickly turned to despair. But just as humiliation set in, an \"Outrageous System\" activated. His first basic Light spell, \"Purification,\" mutated into \"Glory: Explosion\"—then \"Double Explosion,\" \"Continuous Explosion,\" consuming almost no mana but rivaling high-tier attacks! Now, a hidden powerhouse, Song Jie must navigate a world of powerful mages while concealing his absurd strength. What happens when the world’s true dangers force this 'useless' Light Mage to unleash a power that can literally blow up mountains?
