This was the fear of the unknown!
Knowing that they could die just like that, without a trace, and without even understanding how they had died, it made them terrified.
This was the best way to 'conquer' and control a sheep herd, by just killing the one in charge one could make the sheep fearful of himself, and would be able to lead them without a problem.
Just like Tianlong Yun was doing now, even the tiniest movement of his would be under scrutiny, due to the fear they had of losing their life at any moment.
At the same time, none of them would be able to make a move either, fearing that their tiniest movement would make Tianlong Yun target them.
Just like a crowd being in front of a person with a gun, if they jumped all together they might have a chance, but otherwise they were just like loose sand.
