Just now, while going through the formation above, Xu Mu did not detect Yun Mengyao's presence and guessed that she might be guarding the entrance. Now, it seems his speculation was correct.
At this moment, Yun Mengyao was sitting at the entrance, meditating with closed eyes. Around her were layers upon layers of formations and restrictions, making it practically airtight.
Before her was a space crack, as thin as a wall seam, revealing a sparkling clear lake vastly different from the maritime setting behind.
Just like the scene Xu Mu saw back then!
Xu Mu couldn't help but feel a little fortunate. At the time when he discovered this mysterious space, he had been cautious and did not enter. Considering his cultivation level at that time, if he had acted rashly, he might have lost his life.
After his moment of relief, he couldn't help but be troubled by the scene before him.
