The Hidden Scheme (3 in 1)

Underground in Sector R.

No matter how many times humans imagined what the underground looked like, when they first saw it with their own eyes, they realized that their imagination was heavily limited by their knowledge which was not enough for them to sketch out a whole new civilization.

At least, that was what Tang Ling thought.

What exactly was the Underground civilization? After jumping down from the bumpy crevice and shuttling along the tunnels and holes, Tang Ling got a rough definition of what it was—a cave civilization!

Correct, the Underground race seemed to be burrowing holes and digging caves persistently. It was not a simple one-way path leading straight to Sector R in the underground with many turns, holes, and intersecting tunnels all over the place. The underground black market would love a place like this.

The Underground race was not only persistent in digging holes and caves, but they were also skilled at what they did.
