At the entrance to the burrow that seemed more than a hundred meters wide, several Prism Fortresses that were built in a rush were shining, gathering strong energy fluctuations.
Hundreds of soul slaves surrounded the Prism Fortresses. They came in various shapes, but most looked vicious. They were all laid back, either lying on the ground, or eating the dead creatures and plants of the Burrow World.
As the icy cold wind blew, these tough creatures looked as if they were not affected by the freezing temperature at all.
Those soul slaves who could not adapt to the cold environment had long entered the belly of other slave monsters as their energy supply to survive.
Roar!
Several soul slaves lying lazily on the snow ground suddenly raised their heads. After a few roars, they rolled on the floor and continued to lie lazily on the ice-covered ground.
It seemed that these short roars were the way these simple-minded soul slaves showed their submission to the sorcerers.
