Another Tang Song

I was on a date, but I was kidnapped into an infinite world to participate in a game of an ancient civilization that lasted for tens of thousands of years. Uncover a corner of history and come to the Tang Dynasty in 744 AD. The task is to become the actual controller of the Tang Dynasty and occupy at least three cities: Chang'an, Edo, Constantinople, Damascus, London, and Rome. The occupation time must be more than one year! The dream started from a building on the Northern Silk Road. This is my life, this is my story.
