Hangye Jjinneun Cheonjaemabeopsa

Verden, a first-tier mage with a genius intellect but no innate magical talent, is condemned to life as a secret test subject after a devastating betrayal at the Magic Tower. Driven by a thirst for revenge and survival, he develops the "Theory of Celestial Reversal," unlocking limitless potential. But with the tower’s dark forces still looming and mysterious organizations entwining with his fate, will Verden’s quest for vengeance and self-discovery lead to triumph, or will he be shackled once more by inescapable limitations?
