Start with Marriage and Fight for World Hegemony

Give him a wife, give him a prince, and give him a fief? If something goes wrong, there must be a pitfall! Li Yun once traveled through time and became the prince of the Great Zhou Dynasty, only to find out that he was about to be sold to the enemy's country for marriage. Isn't this bullying an honest person? Since you dare to grant me royal power and land, don't blame me for hiding my strength and biding my time while working hard! As long as everything is ready, when the time comes, thousands of troops and horses will come out of Beiyan, and the life and death of the princes, generals and ministers will all depend on the applause of this king!
