Lin Qiao squatted by the pit and watched all those snakes darting about. There might not be other animals in this mountain area, but the population of snakes was enormous!
Most of those snakes were poisonous.
A great number of snakes were wriggling out of the pit, but many stayed at the bottom.
Lin Qiao raised a hand and released a stream of black mist from her palm. The black mist grew thicker and larger from her palm, drifting down to the bottom of the pit.
Soon, the mist touched some snakes which all melted or vanished directly. Some snakes only had small parts of their bodies touched by the black mist, and the effect of the mist spread from those parts.
Some snakes had their tails swallowed by the mist. After that, the rest of their bodies disappeared as well, bit by bit. Some snakes had the mist touch the middle of their bodies. As a result, their bodies vanished slowly toward both ends.
Not a single snake survived the black mist.
