The Empress Sent Me to Get Married? Watch Me Restore My Country and Become Emperor!

Plan➕Kill➕Hot-Blooded➕No System As a prince of orthodox blood, he was sent by the Demon Queen to marry a foreigner. Then I have no choice but to grant peace to Heaven and restore the country and proclaim myself emperor! What? Rebel? My name is justifiable! Successfully fixed the bug that the prince has no military power and foreigners have no orthodoxy! Is it a precedent for a prince to marry? That the Turks helped the Han Dynasty was also a precedent!
