Datang: Married Princess Changle at the beginning

Traveling to the Tang Dynasty, Yang Fei relied on his ancestors to leave property, and his life was very nourishing.
On a one-day outing, a girl was rescued, but the girl wanted to make a promise with her body and get married that night.
Unexpectedly, just after the wedding night in the bridal chamber, the father-in-law led an army to kill him. The girl turned out to be the first princess of the dynasty, and the father-in-law was Li Shimin!
Helpless to become a son-in-law, they can only move to Chang'an City to live together.
Since then, Datang has changed.
Li Shimin: "My son-in-law, do you want to be the emperor? I will give you the throne."
Barbarian alien: "As long as there is Yang Shashen in the Tang Dynasty, we will bow down unconditionally."
