A different world (2)

Xia ruofei's mouth was wide open in shock. The strong flashlight fell to the ground, and the light beams danced wildly in the cave. He then came back to his senses and quickly reached out to grab the flashlight.

The diameter of the cave was only a little more than a meter, and it was difficult to even turn around inside.

Xia ruofei shone the flashlight behind him and turned his head around with difficulty.

At the entrance of the cave, there was a slightly shaking pool of water, but it was as if the water was blocked by a transparent cover, and it could not flow into the cave at all.

Xia ruofei guessed that this was the effect of the formation, but he was still very surprised.

It must be known that this was a depth of nearly two hundred meters, and the water pressure was astonishing. To be able to block the water outside, and yet people could easily pass through, this formation was not simple.
