Chapter 307: How is there no door?

It was only after Lin Wu descended that he discovered this was far more than a sealed space—it was an extremely odd and improper one.

Unlike the mining tunnels they had passed through before, this place was clearly a man-made stone chamber, square and symmetrical. The walls, made of an unknown material, refracted a chilling gleam under the flashlight.

Even the ground beneath their feet was comprised of stone bricks that looked unusually valuable.

Not just Lin Wu, but Kate, Zhang Shan, and Xiaoyang were all stunned.

Bo Yuting, the last to come down, also stared in surprise and asked, "What place is this?"

Under normal circumstances, finding such a stone chamber wouldn't have been too odd. The problem was that they were now beneath a mining site, where one would expect to see the kind of tunnels they had encountered before.

The presence of such a site beneath an area designated for mining seemed utterly bizarre.

Moreover, it had never appeared on any map.
