The Only Aura User In Magic World

While the Vampire King quickly returned back to the castle, I opened a portal back to near the prison and easily sneak past all the other vampires and reach the place before the Vampire King did.

Though the Vampire King was quite fast. He's not as fast as Arin though. And he also stopped by the prison to check the prisoners.

Obviously, it's empty. So there's nothing for them to drink.

Rather, it seems like the fact that someone among them betrayed them hit them really hard that they haven't even noticed that all the prisoners went missing. Only now did they realize.

"It doesn't matter. If tonight we decided to join with the Vampire Queen and the others, then there's no need for us to look for humans anymore. Only if we decide to join them," the Vampire King said. Though he didn't say that to the other vampires. Because he's looking straight at the ceiling of the prison. Straight to my location.
