Jerome didn't know the destination of the mutant vampire he was chasing, and he could only track the direction of the teleportation magic fluctuations to keep chasing it. Even though this mutant could teleport short distances instantly, its movements were random and swift, making it difficult for Jerome to catch up with it.
However, considering that tonight was a party to welcome his home, and almost all the creatures in the twelve realms were assembled in the Alpha King's mansion, it made him think that this mutant vampire would appear there. After all, this mutant vampire was alone and couldn't defeat Jerome or Ares. The only way to escape was to create mutant vampires in a matter of seconds, and the werewolf realm was an excellent place to create a new army.
