Foul Smell And Wild Fire

There were hundreds of them all sleeping in front of him. The beetles were as big as a palm and were covering the ground, the trees, and even the canopy above, hanging upside down.

Their bodies were unlike any other insect beast that Lin Mu had seen till now. There was a cylinder shaped growth on the beetle's back that seemed to be filled with some kind of a fluid. 

The 'container' or the 'cask' was translucent, like that of a mosquito's belly, and the liquid inside could be seen. 

"So that's their 'bile'." Lin Mu pointed. 

"Indeed, senior. They will explode that cask when they are attacked and spray the bile everywhere. While it is not corrosive or toxic, it is still strong enough to knock a person out.

Even Nascent soul realm cultivators have fallen prey to these beetles, despite them being weak." Hua Yi informed.
