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.

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.
