The group followed Nie Renwang to the end of the Dragon Path, only to see that in front of the dragon's head was a waterfall sealed by ice, and in front of the dragon's mouth was a giant sphere even larger than the dragon's head. The waterfall's flow fell onto the stone sphere, enveloping it into a massive water ball, but now it had become an ice ball.
Looking up along the waterfall, it turned out to be an underground river passing through this place, just forming this waterfall.
Due to being an underground river, the entrance was extremely narrow, and now it was completely sealed by the ice, with no excess river water flowing down. However, from the frozen form of the ice, one could still make out the full path of the water that had once flowed down.
