Tianyanxian City, covering an area of nearly 20 million miles, can be said to be a real super ancient city.
at least Ye Chu hasn't been to such a large ancient city, but compared with the vast immortal city, the inner part of Yanxian city is not so subdivided or refined.
there are lots of places where there are no buildings, and even a lot of sand can be seen everywhere in the city. It can be said that this place covers a large area, but the real place for people to live and have fun is far less than the vast fairy City, which is not half prosperous there....
