The setting of this article: Vampires are divided into noble and ordinary species. Sucking the blood of dead people will cause harm. The power of the nobles will dissipate for three months, during which their abilities are the same as humans. The ordinary species will fall into madness and kill their own kind and humans. The damage is irreversible. Whether a vampire is a noble depends mainly on the bloodline of his blood relatives.
Ordinary species have no other abilities except basic physical qualities such as teleportation, near-immortality, and flight.
Nobles also have special abilities, but the abilities vary from family to family.
Cannibalism is a felony, but only between people of the same class.
This is the first time I write down my thoughts, science students, I beg you for your writing style.
