Slave of the ???

My name is Reed, an orphan turned soldier forcibly facing several horrible laboratory tests. Facing imminent death, I stroke a desperate deal with the devil. Saved from the brink, I awaken to find Earth transformed—gone is the world of democracy and technology, replaced by one teeming with magical creatures and powers, where strength reigns supreme.

Driven by a desire to survive the cataclysm and discover my enigmatic savior, I embark on a quest for strength. But I soon learn my body is far from ordinary, and the path to power is shrouded in mystery. With no other option but to unravel these secrets, I set forth on a journey filled with both triumphs and trials.
