[Lord + Western Fantasy + Lord + Slow Burn + Conquest + Multiple Races + Animal Girls + Technological Overpowerment]

As the king's marshal father was defeated and disappeared, Leon Auster was demoted from heir to duke to baron overnight and exiled to the northernmost part of the kingdom, to the wild swamp where he lived among barbarians and monsters.

He starts with a barren land, three jingling silver coins, and a delicate and beautiful wife.

Leon: "Okay, okay, so you're going to play it this way?"

You think exile will destroy me? You've invited a god into the newbie village!

You consider it cursed black swamp soil? Sorry, that's my vast fertile land!

A savage tribe feared by all? Sorry, from now on they're my loyal soldiers!

The royal family, high and mighty? Wait, I'll be up there soon and we'll talk about what "divine right of kings" really means!

Soon after—

The Emperor: "Where's the useless lord we were promised? How come his grain can feed the entire continent?"

Duke Firehawk (father-in-law): Daughter, are you sure Lyon still needs my protection? I have a feeling he's about to buy my duchy.

Abyss Demon God: "??? Where is my demon army? Why are they all digging potatoes in that baron's territory?"

Lyon: Exile me? The biggest mistake you ever made was giving me a piece of land.
