The First Prince of the Tang Dynasty

Li Qing looked at himself in the bronze mirror in front of him, and he still felt like he was dreaming. Five years ago, he accidentally traveled through time and became Li Chengdao, the second son of the current prince Li Jiancheng. Of course, after his eldest brother Li Chengzong died of illness, he became Li Jiancheng's eldest son. At the same time, he is also the nominal grandson of the current emperor and the future third emperor of the Tang Dynasty!
