When student Falion wakes up in the body of twelve-year-old slave Ethan, he finds himself aboard a ship bound for Purgatory Island—a secret research outpost where the empire's greatest alchemist, Darragh, forges war golems from rare magical resources. Falion quickly realizes the horrifying truth: servants disappear monthly, their numbers matching the golems shipped out. Armed with a scientist's mind from his past life, he outsmarts his captors at every turn—cultivating rare magical plants, earning library access through literacy, and trading cooking skills to the elite warrior Hadrian for combat training. As Falion masters Dou Qi energy and rises to head servant, he uncovers a paper trail linking missing children to flesh golems. The chapter ends with Falion slipping into the forbidden valley at night, determined to confirm what he already knows.
