My Wife Said She Is Li Shimin's Daughter

[Love] [Relaxation] [Daily] My name is Liu Lingfeng, an ordinary history teacher. One day, I picked up a girl who claimed to be "Princess Li Mingda of Jinyang". She said that her father was Li Shimin and her brother was Li Zhi. She also said that she should have died at the age of twelve. I thought she was doing immersive cosplay until— While washing the dishes, she casually hummed the original score of King Qin's Breaking the Formation, and modified the errors in the "Old Book of Tang" with ease, and whispered to me: "Liu Lang, the historian made a mistake here." So, now comes the question: How should I prove to the Civil Affairs Bureau that my wife really came from 1,300 years ago? ………… Liu Lingfeng: Your Highness, in the Zhenguan era, who would a girl like you usually marry? Li Mingda (smiling slightly): "Well, I can marry a noble man, or a talented and famous minister. But... If I meet a gentleman who is willing to rewrite history for me, it seems that it would not be a bad idea."
