I imagine that the vampire demons in ancient China are the ancestors of the prosperous vampire clan. I imagine that the vampire demons lived like this in a dynasty that is far away and strange to us. They practiced, cannibalized, practiced again, and cannibalized again, repeating the decay over and over again, a life that never gave up the search for life. In fact, vitality can be irrigated by love. Perhaps love is the only way to save the "demon" from water and fire. So is that really the case?
