Datang: I Am a Time Traveler, What's Wrong with Building a City?

Datang + System + City + Technology + Formation of Forces Also known as "Datang: I have already planned my life, but you told me there is a system!" Late dog system. As soon as I got on the stage, I was given the "Two Iron Laws" and the "Four Points of Attention" System "Hosts please remember the iron rules of the system. Violators will be severely punished..." System "Iron Rule No. 1: Do not marry Princess Changle, Wu Zetian and other influential figures in history" The second iron rule of the system: "You are not allowed to serve as an official in the court"... They even suggested that I build an independent city! Ye Tianji looked at a series of instructions for using the system, and with his decades of cultivation, he couldn't help but break the defense!
