At the Above Immortal Realm.
The Tianyuan Immortal Town.
The Above Immortal Realm was different from the Immortal Realm. The Immortal Realm mainly had ordinary people. Therefore, their major towns would rely on kingdoms, sects, or cultivation families to stop the demons.
On the other hand, the Above Immortal Realm did not need to worry about that. They had locals, too, but a lot of them were cultivators. Some of them were as powerful as some Immortals. Moreover, everyone at the Above Immortal Realm was not weak so they did not want to rely on sects. There were a lot of solo cultivators, too.
A lot of towns in the Above Immortal Realm had a mixture of ordinary people and Immortals. No sane demons would attack the towns.
Thus, people from the towns did not need to rely on other forces. Some towns were even better than some sects in the Above Immortal Realm. Towns were nice places for Immortals to gather and hang out.
