I Am the Real Crown Prince of the Tang Dynasty

I don't write novels, but in Chang'an City, a porter in parallel time and space, there appeared an outstanding young man who didn't know who his parents were. He sometimes dreamed of strange and weird pictures, and he learned a lot from the pictures. Li Shimin and Changsun didn't know that they actually had a child living among the people. That year, Li Shimin went on an expedition, and Li Jiancheng was still there. On the day when the eldest son gave birth to his son, he was taken to Tai Chi Palace and looked after by Li Yuan. What happened that year? The only person who knows is Li Yuan, but will he tell it? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
