Unknown Hazard!

Feng Luo pointed to the building covered in sand and said, "I've been thinking... That is probably the system's hint!"

Burnt And Run looked puzzled and asked, "Huh? That's the hint?"

Feng Luo nodded.

"The display on the recon meter showed that the monsters were not moving in a straight line or a curved line. Instead, they were moving polygonally in some of the areas. It looked as if they were moving upwards through something that might be staircases or something of that sort!"

"The recon meter's ruler also noted that they were located at a depth of 30 meters. This has already exceeded the theoretical height of the sand dune!"

Chairman Jiao's eyes lit up. "Brother Feng, what do you mean?"

Feng Luo then explained the reason he made that judgment.
