411 Underground Ocean, Undersea Town!

The deeper they went, the more rugged the tunnel became. Most of the tunnel had been blocked by rubble. Team Tiger Deity had dug out holes that allowed one person to pass through with all fours at a time.

In the endless darkness, the feeble brightness leaked out from the tiny gaps near the tunnel now and then, as if thousands of narrow and long eyes were observing the intruders without blinking.

Li Yao and his teammates rapidly proceeded through the tunnel. Half an hour later, they arrived at the end of the tunnel 9,500 meters below the ground.

Although they'd been prepared for unusual things to happen, the splendid scene they were welcomed by still shocked them. At the end of the narrow tunnel was a boundless underground world that was at least a hundred times larger than the previous one they had been in. They could not see the end of it. Everything was enveloped in darkness.
