章 776: A Formation Nexus

The distance to the cave where the Former Adviser Chu built the teleportation formation array to escape the wandering sinkhole was about a kilometer away. Lin Mu could feel the suction force getting a bit turbulent the closer he got to it.

He also realized that the 'Tunnel' was slightly below the cave. Lin Mu reached it after about ten minutes and saw what looked like a vortex below it. There was not just one, but eighteen such tunnels joining it. 

"So many… does this spread all across the plane?" Lin Mu said upon seeing it.

The vortex spun at a constant pace and the spirit Qi from the tunnels kept on getting condensed within it. Lin Mu did not know how this was formed, but he was sure that it was certainly not natural.

Lin Mu then rose up and appeared on the surface. He looked around and saw that there were a few glowing crystals in the cave that illuminated it. The light was dim, but for Lin Mu, it was still enough to see everything clearly.
