Chapter 2819: The Ancient City Wall

Mo Fan and Mu Bai had assumed that with their current strengths, they could do anything they wanted at the Bug Valley of Helan Mountain. 

However, the situation in the Bug Valley was more dangerous than it appeared to be. Every different creature had their own principles. The bizarre Star Bugs possessed extremely powerful soul-sucking abilities. The moment Mo Fan, Mu Bai, and Song Feiyao entered the Bug Valley, the Star Bugs slowly absorbed the intruders' soul energy.

If it had not been for the fact that Little Loach warned Mo Fan about the Star Bugs, they would have only found out about them by the time most of their soul energy had been sucked away. 

The valley was enveloped with fog that had anesthetic effects. The Fog Leaf Bug was the source of the anesthetic fog. They were a perfect match for the strange Star Bugs. The Fog Leaf Bug spread anesthetic fog in the air while the Star Bugs sucked humans' souls.
