"Other than becoming stronger and losing their mind, what else will happen?" Albert asked the female vampire.
"I don't know. We also thought that those were just myth. And there hasn't been any case of someone drinking another vampire's blood," the vampire said.
"There have to be at least one case of a missing vampire. After all, your king suggested this plan to half of the vampires here. Which mean he already know that it will work," Albert said.
"…there were some missing vampires. But they were just some low-rank vampires, and no one cares about them gone," the vampire explained.
Albert start thinking for a bit.
In the battlefield, Kayla and the other expert level mages have started fighting the crazed vampires. Those vampires don't even care how injured they are, and as long as they are not dead yet, they will attack anyone in sight. Even their own kind.
Basically, the battle has changed.
