Calhoun used the rod to hit Greyson, and if the demon was a human, the person would have died by now. "W-wait, you can have the dark angel. I-I will be your loyal servant!" Greyson tried to lay a trap for Calhoun, but the younger vampire was smarter than that.
Calhoun stared at Greyson, "I have a question for you."
"Anything!" agreed Greyson. Calhoun dropped the rod on the ground, and in a blink of an eye, he pulled out the gun and shot Greyson's leg, and heard the demon scream in pain. "Why did you do that! I told you I would answer your question! Ugh!" he groaned in pain.
"For inviting yourself in my castle without any invitation," came the calm words from Calhoun. "I got these bullets specially made for demons like you. You didn't feel the pain earlier, but you will feel it now. Your body will try to turn like a human body when it comes to pain. Even a pinch will make you wince. Isn't that wonderful?"
