Exiled with Prisoners, I Built a Sea Empire

A survival expert wakes as a disgraced prince exiled to a barren island with a group of female prisoners. With no food or fresh water, he uses modern knowledge to desalinate seawater, forge iron, produce salt, farm the land, and build a fortress. He transforms the prisoners into an elite naval force—and when pirates invade, gunpowder and bronze cannons turn their island prison into the heart of a new empire.
