I Become an Evil Mage in the Middle Ages

A slap from his junior student sent Li Dong to a medieval continent, where his soul possessed the body of a young man. This world is full of brutal orcs, beautiful elves, holy knights, and an evil mage named Cassius.

Just how evil is he, you ask?

The orcs say he loves peace, the elves praise his respect for nature, and the knights commend his impeccable conduct.

He lifts the greatsword off the orc’s neck, cancels the forbidden spell he was about to cast with his right hand, and raises the foot he had planted on the knight’s back.

“So you’re saying none of you started calling me the Evil Mage Cassius?”

Everyone hurriedly nods.
