That kind of Hell's Gate...was permanent!
The shock in Ye Lingchen's eyes became even stronger. For so many years, there were only four permanent Hell's Gates in the entire China, which showed just how rare it was for a permanent gate to actually occur.
There were three ways to distinguish between permanent Hell's Gate and temporary Hell's Gate. The first way was dependent on spiritual energy. If spiritual energy continuously overflowed and showed no signs of weakening at all, then there was a high probability that it was a permanent one. The second depended on the fluctuation of the vortex. The speed of a temporary gate's vortex was slower and the texture was relatively fuzzier. The third was by its duration—temporary gates generally lasted no more than an hour.
All signs pointed to the gate being a permanent one!
