Supreme Spouse System.

Leon Walker, a jaded genius from the modern world died… embarrassingly, thanks to the notorious Truck-Kun. But fate wasn't done by his death.
Born again in war-torn Galvia, he finds himself inside the powerful, yet decaying body of Duke Leon Moonwalker, one of the great and powerful Dukes of Moonstone kingdom.
Just as hope is lost, a cheeky voice purrs in his brain:
"[Supreme Spouse System Activated]"
The Rules are simple: seduce. conquer. rise.
Each woman he conquers makes him stronger — gifting him their abilities, bloodlines, and precious talents. The stronger (and more deadly) the woman, the better the reward.
With a wicked smile and a system designed for power and pleasure, Leon dances through lethal politics, seduces war lady’s, Nobel-woman and queens alike, and brings down empires with a wink and a sword.
Strength is the law in Galvia.
Leon?
He'll rewrite the rules — one stolen kiss, one conquered throne at a time.
Because when you're charming, deadly, and a little bit crazy.
why just survive, when you can own everything?
