I, a Legitimate Prince, Actually Asked Me to Get Married?

I, Li Nian, traveled through time and became the crown prince of the Zhou Dynasty. I thought I could live a happy life with three thousand beauties in the harem. When I found out that my mother rebelled and seized power, I was deposed as the crown prince. I originally thought that it would be good to be a free prince, but unexpectedly I was sent to the grassland to get married according to an imperial decree. ….. I am the Great Khan of Mongolia. I thought that the Central Plains Dynasty would send a palace maid pretending to be a princess to deal with us. Who would have thought that it would be a deposed former prince who married me? Now I am the orthodox one! Son-in-law, no, Your Majesty, it's getting cold. I'll give you some extra clothes! Your Majesty, when will we send troops to attack the rebels? Your Majesty, don't forget me, the father-in-law, when the time comes. Li Nian: Mother, if I don't punish the rebellious, this is what I will be like?? If you don't run away, this is what you will be?? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
