Agricultural science PhD Lin Sui opens her eyes to find she has become the disgraced crown prince’s consort, soon to be exiled three thousand li away.

Her husband, Xiao Jingyu, has had both legs broken. Once a brilliant and celebrated heir to the throne, he is now utterly hopeless, waiting for powerful ministers to send him to a frigid land to die.

Lin Sui has no intention of waiting to die.

On the eve of the confiscation of their property, she brings her super-spatial department store, sounds the grievance drum, storms into the imperial presence, and lays a world map, high-yield potatoes, and firearm blueprints on the imperial desk.

“Your Majesty, beyond your realm lie thousands of miles of territory. Don’t exile us. Give me a fief, and I’ll fill your granaries and send your iron cavalry across the seas.”

The suspicious tyrant studies the map and seeds, then changes the imperial decree.

And so exile becomes a fief, and a frozen wasteland becomes an experimental farm.

Lin Sui grows potatoes, builds canals, opens workshops, and manufactures firearms, transforming the barren wilderness into the wealthiest fortified city on Great Yin’s northern frontier.

And one day, the disgraced crown prince she saved returns to the capital with a sword in hand.

“Sui Sui, you gave me a way to live. I’ll win an entire realm for you.”
