Tang Yuan, the most unpopular third princess of the Rouran Kingdom, was treated as a substitute for the arrogant princess due to a marriage decree. She was married to the Jing Dynasty, a great country in the north, to marry the legendary Zhenbei Crown Prince Xie Wuyan, who was ruthless and violent, and killed three concubines.
Everyone was waiting to see this "little white rabbit" being torn apart by the big bad wolf. Unexpectedly, Tang Yuan, relying on the survival philosophy of "food first, life first", not only used the "Royal Pig Raising Method" to feed everyone in the palace to obedience, but also inadvertently discovered the only golden finger brought by his "pregnancy" - communication with animals. She took the prince's snow wolf and falcon with her and became prosperous in the north. From the initial indifference and suspicion, Xie Wuyan later discovered that this seemingly silly little wife was actually the only good medicine to cure his old illness and psychological trauma. Just as the relationship between the two was heating up, Tang Yuan unexpectedly became pregnant, but due to a political conspiracy, she ran away with the "wolf cubs". Xie Wuyan chased his wife for thousands of miles, and finally realized that he was the one who was saved by the "marriage" policy.
