Instant-Cast Forbidden Spells with No Cooldown? I Am the Calamity That Ends the World

Games have descended into reality, and the whole world has entered the class-change era. Jiang Yuan changed class into an ice mage, but he’s just a tiny bit different from ordinary mages! What the heck!? Where are the Ice Spike and Frost spells I was promised!? Why does this mage have nothing but forbidden spells!? The ice-type forbidden spell Frostmourne, the fire-type forbidden spell Wrath of the Fire God, the wind-type forbidden spell Sigh of the Wind... Wait... What the heck is a wood-type forbidden spell? And why is Susanoo here!? On top of that, these forbidden spells can be cast instantly with no cooldown! Many years later. Jiang Yuan stood at the summit of the gods, looking calmly at those who came after him. “Have any of you ever seen what it means to carpet-bomb the land with forbidden spells?”
