Urban God of Magic: Infinite Mana Blows Up the World

Title

“After awakening an eternal magic core, Lin Ye becomes a BUG-level mage in the city. While others exhaust their mana casting fireballs and collapse from fatigue, he casually unleashes forbidden spells that blanket the land. While ability users show off their shields, he stacks a hundred layers of Thunder Judgment and blasts them and their shields to smithereens. Demonic beasts invade? Rifts to other worlds open? Sorry, the God of Magic with infinite mana is only here to turn everyone who dares oppose him into fireworks!”
