"A Master of Transformation's blood is the last you try to suck. Tsk." Klaus clicked his tongue, as if he were sorry for the intellect of this ancient vampire.
Lucien chuckled. "In fact, the Master of Transformation's blood is the best. If you suck one of them, you will be essentially sucking countess races. But he shouldn't have sucked Erica's blood when she became a seraph. He must've been desperate about his life."
