In the South Sea Territory, almost everything is oceans, and even between the islands, there are vast expanses of sea.
As such, if one wants to travel, they must use ships.
Not all cultivators can fly, and for long distances, even those in the Dragon God Realm or Dragon Emperor Realm don't want to stay in flight constantly, because they have their own matters to attend to and can't waste all their time flying.
Therefore, the ship industry in the South Sea Territory has always been extremely prosperous.
Ports emerge in endlessly, especially on those huge islands where there are one, two, or even more ports.
On the island where the Phoenix Sect's sect residence is located, there are as many as twelve ports, and the one where Su Han has arrived is not the largest, but it is of a decent size.
Ten years ago, Extraterritorial Demons ran rampant, and almost all the ports were destroyed.
