"You're evil," The vampire said after I poured water on her.
"If you are wondering how I killed your king, you just found the answer. Now, we will ask you questions and you will answer everything truthfully. Or I will ask our water mage to drown you all. You and every vampire that we fished out of the lake," I threatened her again.
"Please don't! Vampires can't swim! We can stay long enough underwater using blood as our energy, but we can't swim! If you do that while we are vulnerable, we will die!" the vampire shouted.
"Then you should answer everything truthfully."
More importantly, I was right that the vampires can't swim. If only Albert would bet on it, I would get some money. But I guess it's fine as well this way.
But how come vampires can't swim? Let's see their bodies.
Hmm? They are far weaker than before. They must have used all the blood they have to survive underwater.
