I, Li Anyu, a sophomore, was on the way to an outing organized by the school when the bus I was riding lost control and rushed off a cliff! Just when I thought I was dead, I miraculously woke up and became the third young lady of the Li Mansion... The third young lady of the Duke of Tang's Mansion! That's right! They are the third daughter of the founding emperor of the Tang Dynasty, Li Yuan, the famous Princess Pingyang Zhao, and the biological sister of Taizong Li Shimin! What the hell is this? What worries me the most is that at this time, I am still just a little baby with a height of three inches! And the slug I was holding in my hand turned out to be the future cannon fodder--Li Jiancheng! God! Help me!
