"Kill Each Other" 

Still, Ainsley knew that the demons could not be killed by blood suppression alone because even if they could be greatly injured, the special bodies of these demons would allow them to recover naturally. 

And so, the greatest effect of blood suppression was naturally the deterrent effect and the ability to make these demons, even the mid-level ones, obey. 

It was just that, these demons could not commit suicide because they couldn't really kill themselves due to their unique body structures. 

The only thing that these demons could do to benefit humans was probably to start fighting among themselves. 

And so, since Ainsley sensed the few hundred bloodline threads connected to a lot of low-level demons and a few mid-level demons, Ainsley didn't hesitate to give her first command.
