I Transmigrated as a Princess Sent Away for a Political Marriage and Opened a Hot Pot Restaurant

The heroine transmigrates into the role of a princess sent away for a political marriage, but flees halfway there and opens a hot pot restaurant on the border. When enemy troops invade, she splashes a bowl of spicy malatang at them. The soldiers are so overwhelmed by the heat that they howl and flee the battlefield for good. When the emperor hears about it, he flies into a rage: “I sent you to marry for peace, and you drove them away? Get yourself to the harshest, coldest frontier!” The heroine takes her hot pot recipes to the frontier, opens branches, develops trade, builds cities, and eventually helps the second male lead rebel, kicking the original male lead to the curb...

The pitch in one line: I won’t marry for peace, I’ll just open restaurants. I won’t get married, I’ll be the empress’s boss!
