At this moment, Ding Fan was feeling quite serious, as he was still completely unaware of the situation outside. When Ding Fan released his Divine Sense to probe, he couldn't detect what was going on outside the Sword Washing Pool, which was not a good thing for Ding Fan. Even the situation outside the cave couldn't be detected with his powerful Divine Sense, considering the distance between the Sword Washing Pool and the cave entrance was rather remote.
Moreover, there was a formation in the Sword Washing Pool that suppressed Divine Sense; Ding Fan hadn't undone this formation earlier. Initially, Ding Fan thought that the formation suppressing Divine Sense would be quite challenging to crack but wouldn't have much impact on them, yet now, unexpectedly, this suppressing formation had made them so terrified.
