"Teleporting Out" 

Even after Ainsley and the others killed a lot of demons, there were still a few hundred thousand demons roaming around the snowy mountain and the fairy of space caught them all inside the space barrier. 

These demons were trapped, and so, it only took the fairy a few huge teleportation tunnels to transport these demons out, back to where they belonged. 

Since the fairy had already infiltrated the island, it was easy to create a stable teleportation tunnel, but she didn't care much about whether the tunnel was safe or not for these demons. 

These demons could just die inside an unstable space tunnel, but it would be bad if the demons were teleported anywhere else other than the abyss. 

If the demons were teleported to some random places in this world because of the unstable space tunnel, then, the fairy would be in a lot of trouble.
