The two of them followed the mountain path for many kilometers, and soon, the two of them heard the sound of water flowing.
They flew through the tunnel and landed on the ground.
This was a sparse underground area, and there were all kinds of crystals on the walls. There were also man-made lamps that lit up this area.
In front of them was a river that was about 15 meters wide. The water was very steady and flowed out from the darkness and to the darkness on the other end.
Upon close inspection, they found that the water was quite strange; it looked like dense fog, but the sound of flowing water was unmistakable.
"Is this Fate Emperor River?" Zhou Xuanji asked out of curiosity. The spirit qi in the surroundings was very dense, and it was comparable to the summit of Skyfall.
Founding Emperor Chi Wei said in amazement, "This is the first time I've seen Fate Emperor River. It's said that Fate Emperor River flows in a cycle and will not evaporate."
