You're Sending the Crown Prince to Marry for Peace? I'll Take the Throne Instead!

Wei Heng transmigrates into the fourth prince of the Great Zhou Dynasty, a prince unloved by the emperor and humiliatingly sent to the northern desert to marry into a foreign tribe. Emperor Wu of Great Zhou: “That good-for-nothing will be put to use in the northern desert, at least.” The other princes: “At last, we’ve gotten rid of the greatest threat to the throne!” Wei Heng sneers: “You’re all delighted to send me off to marry. But once I unite the world, you’ll have no idea whether you’ll live or die!”
