章節 1532: Underground Sewage Treatment Pool

Soon, Meng Chao scanned the main channel of the underground river, as he could see through the nine layers of rocks. The river was reminiscent of a crouching flood dragon.

"I've figured out the location of the underground river!

"Based on the subtle sound of the water, the amount of runoff in this section of the river is high. The width of the channel is wide enough for an adult to sneak in!

"Next, I just need to find a crack that can lead me to the underground river!"

The earthquake that had just passed had torn a lot of cracks in the rocks above the underground river.

Although most of the cracks were so narrow that it was difficult for even a finger to go through them, his hard work paid off.

After more than half an hour of scanning, Meng Chao found a crack that was the most severe and closest to the underground river.

The size of this fissure was still not enough to accommodate an adult as a route to the underground river.
