Although there were no city walls or any similar protective constructions, at first glance, Peter Brown was clearly able to identify it as a city. Moreover, it was a city that was meticulously guarded.
Seeing the astonishment on Peter's face, Levi West burst out laughing, "Never seen anything like this, have you?"
"Yeah, it's surprising to see a city without any defensive walls."
Levi chuckled, "Think about it. What kind of place is the Cultivation World? It's where those who soar high and low dwell. What use would the city wall serve? Surely, you don't think the cultivators can't get into the city?"
Peter pondered for a moment and found it logical. Clearly, his understanding was influenced by the mortal cities on Earth. Obviously, cultivators could fly, they could easily get into a city, irrespective of how high the city wall is.
