Transmigrating to a mist-shrouded alien world, a former deliveryman is sold as a slave to twin sisters with a scandalous mission: producing an heir for an aging baron. This triggers a powerful system that grants him superhuman abilities. Fighting his way up from servitude to absolute sovereignty, he slaughters mutated beasts, forms unbreakable bonds with powerful women, and shatters the toxic fog cursing the planet—only to face an even deadlier, unknown threat emerging from the East.
