Global Magic: I'm a Mage of Every Element, with Unlimited Power-Ups

[Magic + Invincible + Genius] This is a world of magic where mages reign supreme! At the Battle of Red Cliffs, Zhou Yu, a Saint-tier archmage, unleashes the ultimate forbidden spell, Heavenly Fire Across the Plains, and burns Cao Cao’s army of tens of thousands to the ground! At the Battle of Kunyang, Grand Magus Liu Xiu... Qin Cheng is reborn with the Infinite Enhancement System. Anything and everything can be enhanced without limit. From the start, he awakens every elemental affinity and becomes the only all-class mage in the world! And so, a terrifying all-class mage rises, striking fear into the hearts of all! Seeing a Fireball spell powerful enough to destroy an entire city, the mages cry out in disbelief: “You’re telling me that’s a low-level spell?!”
