People Are Engaged in Construction in Datang, and My System Is My Father

(Avatar history + Tang Dynasty + System + Relaxation + Ancient times) "My name is Li Ke, and I am now the third son of Emperor Taizong Li Shimin, King Wu Li Ke. Originally, I just came to the Tang Dynasty to collect historical information, but I ended up meeting my long-lost biological parents here and was forced to join the "God-making Project"!
