Unexplored region
The Tier-9 Black Centipede had long since retreated to the deepest part of the unexplored region.
When the Tier-9 Lords appeared, the beast sensed their presence. But it had already moved out of the influence of the border area.
Right now, the deepest part of the unexplored region has most of the corrupted beasts living in groups.
There are Tier-9 Beast heads among the different groups as well. The Tier-9 Black Centipede is alone. There are many beasts roaming alone as well.
It would be hard for the lords to find out the real beast in a short time. Unless, they spend time examining the poison.
Right now, they don't know which beast was responsible.
On the other hand, the four lords are going inside the unexplored region. They have yet to release their Lifeline beasts.
But they can communicate with their lifeline beasts in the mental zone. There is a risk of releasing the lifeline beast here.
