Seeing their comrades being sliced in two without any noise, the silent yet creepy scene caused many of the riders to be filled with horror.
In the dark of the night, all the riders could see was pitch black, since White Bones had already evolved and its entire body was black. The riders could only see their friends charging, and suddenly, their bodies separated, and fresh blood sprayed everywhere. It was enough for them to feel chills down their spines.
Even the leader of the 3,000 riders, a powerful Evolver had been sliced in two in the middle of his charge.
Witnessing this horrifying and mysterious scene, the remaining 1,000 riders felt apprehensive and were immediately pounced on by the treants which had no concept of fear of death. The entire unit soon collapsed, with many of them turning to run in different directions.
