This is not a stone man at all, but a cave mansion!
Now it's very obvious; this is entirely a special space, only revealing the situation of a stone man, and the only key to enter the cave mansion is for those two pools of water to be completely absorbed.
Peter Brown's expression also became strange at this moment; he really didn't expect it to be such a situation. He needed to know that these two pools of water were something that others, especially those trapped inside with sealed cultivation, couldn't do anything with. Even members of a family couldn't absorb them unless their Divine Sense reached a certain level. However, Peter was an exception; he possessed a vast Ocean of Divine Consciousness with an infinitely large Space Domain for his Elixir Sea, allowing him to incorporate any amount of Divine Sense.
In this kind of situation, what is extremely difficult for others is a simple matter for Peter.
