A mage in the making: Unlocking my mage system

[ Congratulations, you have successfully acquired A Mage's System ]

Chuck Nectar, a boy who was born with the most unfortunate disability that one could ever have, lived in a world of mages where magic and cultivation was possible.

Being born without the ability to wield any magical affinities, he was bullied, pushed around, and treated like trash.

Chuck was forced to live as an outcast. That was until he stumbled upon a mystical energy that got absorbed into his being.

Unlocking a system that granted him numerous benefits, Chuck finally found a way to grow strong, exceeding everybody's expectations.

Unbeknownst to the people of Earth, an alien race from another dimension, sought out on a mission to conquer as many planets as they can, had chosen Earth as their next target to enslave.

From being a weak mage to a being surpassing any human limitations, Chuck must decide whether or not, if he is going to use the powers of his mage system to defend the earth from its invasive threat.

Is he going to defend the people that looked down on him, or let them suffer the wrath of other dimensional beings...
