Something Weird in the City

This city did have its walls even though it was underwater. At first, it looked ridiculous since anyone could simply swim and completely ignore the walls. However, Rean quickly noticed that those walls were not just for decoration. "All those walls have formation runes on them. Look at the demon beasts and humanoid races coming and entering the city. They're all passing through the gate. No one is trying to fly over the walls. There's a formation protecting the entire undersea city."

Rean was right. The formation wasn't possible to be seen with the naked eye, but it really was there. Without much choice, Rean's group had to go to the gate as well. Fortunately, there were enough aquatic demon beasts and humanoid race guards to take care of the screening process, so the queue moved very quickly.

Once their group finally arrived at the gate, one of the guards quickly asked, "Reason for the visit?"
