Revival of Magic: Billion Times of Evolution

George transmigrated into a world with magical elements and a battle aura. Unfortunately, his talent was too low and he did not have any achievements.
To his surprise, on his 18th birthday, when he was playing an online game, he realized that he could evolve abilities.
The evolution of his fire attribute magic went as follows: Fireball → Flame Shock → Flame Storm → The Burning Gate of Hell!
The evolution of his light attribute magic went as follows: Illumination → Light Saber → Divine Light → The Sacred Curse of Light!
The evolution of his dark attribute magic went as follows: Inferno Fire Blast → Corrosion of the Dark → Domain of the Dark → Destruction of the Dark!
He could even evolve space attribute magic. It went as follows: Item Shifting → Space Quark → Teleportation
George unleashed 10 Fireballs. Immediately, the 10 Fireballs evolved into 10 Burning Gates of Hell.
When the intense flame set the sky ablaze, the demonic creatures were stunned. The humans were stupefied too.
