I! The All-Elemental Mage! Sign-In at the Imperial Academy!

When Du Wei opened his eyes, he discovered that he had transmigrated to a world of swords and magic.

He was a janitor at the Magic Empire Academy in the Emerald Empire.

This was a world where everything else was inferior, and magic reigned supreme. In this world, mages stood above all others.

Just as Du Wei was about to despair, a god-tier sign-in System suddenly awakened, and so Du Wei began his sign-in journey.

"Ding! Congratulations, Host, you have successfully signed in at the Magic Aptitude Testing Ground. Reward: perfect affinity with all elements of magic."

"Ding! Congratulations, Host, you have successfully signed in at the Fire Magic Tower. Reward: the Fire God's divine core."

"Ding! Congratulations, Host, you have successfully signed in at the Magic Library. Reward: the ultimate forbidden spell, Fall of the Gods."

"Ding! Congratulations, Host, you have successfully signed in at the Imperial Divine Armory. Reward: the sacred magic artifact, Kingdom of the Undead."

And so, fifty years later, when the billions-strong Orc Empire marched into the Emerald Empire, Du Wei appeared before the world with all kinds of divine artifacts in hand and the power of a God of Magic.
