I Became a Fallen Kingdom's Princess, Emptied the Treasury, and Went into Exile

The modern world’s strongest female agent transmigrates into the body of a pitiful princess whose country has fallen and family been wiped out!?

Her prince consort father plotted a rebellion, the entire royal clan was massacred, and her ungrateful husband and scheming best friend join forces to mock her as a foolish airhead!?

Backstabbed and betrayed, she must flee into exile for a thousand miles with the few favored consorts left in her palace and her little brother!?

No problem. With a pocket dimension full of supplies, she turns around and empties the national treasury and the homes of the traitors, steals the imperial seal, and still eats like a queen on the road to exile!

Once she reaches the wilderness, she can build a fortune and raise children at the same time, turning the wilds into a paradise!

But why has the hostage prince from a neighboring country, whose engagement was once broken off, followed her here and refuses to leave?

What? He’s frail and needs adopting?

Help! She doesn’t want to! What should she do?
