From Death Row to Throne

A premier modern operative transmigrates into ancient antiquity, waking up chained in a damp dungeon cell as a condemned felon. His dire predicament reverses when he triggers a mystical combat interface that exponentially multiplies his physical strength with every hostile enemy he slays on the battlefield.

Enlisting in the frontier legions, he forms a covert alliance with a brilliant female general, pretending to switch allegiances to outmaneuver enemy command. When corrupt imperial ministers frame him out of fear, the unstoppable warrior marches directly into the throne room to depose the tyrant.
