Why was it called one of the Centers of the leaping Dragon World? it was because the leaping Dragon World was too large. There were a total of 81 big cities like Shangshan city. The first big city was built by a super sect in the true spirit world. It could be said that the first big city was the center of that area. Therefore, Shangshan city could only be considered one of the Centers of the leaping Dragon World.
Every big city was a super sect, and every super sect was the boss of their respective areas. This was the current situation in the leaping Dragon Realm.
Of course, this didn't mean that there was only one branch Hall of truth sect in Shangshan city. In fact, there were many branches of small sects and medium sects. But if these sects wanted to stay in Shangshan city, they had to serve the city, protect the city's security, resist the attack of demon beasts, and so on.
