This is the place where the two of them had just been teleported to. Li Yifei made a special note of it. The ground here was no different from any other ground, but the four surrounding walls and the space a few meters above their heads also had an invisible force trapping them.
As expected, there was a formation method in this hall. The fact that there was a formation was what Li Yifei anticipated, but how should this formation be broken?
After thinking over and over, Li Yifei returned to the starting point. Since the walls could not be pushed down or penetrated, and since there was nothing unusual about the surrounding ground, then how were they teleported in? There had to be a method, or a space.
Even if it was a conduit? Li Yifei stood in the original spot, Xu Shanshan stood next to him. Although feeling a bit anxious to get out, neither of them was in a panic. They had encountered things more dangerous and difficult than this several times before.
