A sudden attack?

Mo Qiang stared at the pit, her eyes were narrowed with suspicion as she crouched on her heels with her soles raised in the air. She sniffed the air through her mask and was surprised when she did not find the scent of rotten flesh and blood. 

Even if the Ruby Head Snake gobbled the mers and children that were sent to this pit whole. How in the world did it not make a mess? At least a bone or drop of blood should have been left behind in this pit, right? However, there were no traces of any human being eaten alive here. 

Was it even possible for the Ruby Head Snake to drag its victims somewhere else? But even if could do that, there was no way it could drag each and every person who was thrown in the pit, right?
