Zhou Zekai is a pure vampire (his ancestors have been vampires for generations, and no other creatures participated in the marriage)
Pure vampires can turn humans into vampires by sucking human blood.
Human-turned-vampires rely heavily on the blood of pure vampires.
Non-pure blood vampires will not turn humans into vampires if they drink human blood.
(The concept setting of pure vampires comes from "Vampire Knight", a very good girl's comic!)
Vampires suck each other's blood to represent their love. The general food source is human blood banks. If they are hungry, they may attack humans. If they drink too much blood, humans will die.
In an era where non-humans and humans coexist, humans do not know that there are various non-human beings around them.
In addition to vampires, there are also fairies, mythical beasts, and vampire hunters in this world.
Generally speaking, there is harmonious coexistence, and other creatures are trying to learn survival skills and integrate into human society.
Vampires' appearance will not change after they reach adulthood and they will live forever.
Sun Xiang is human. Zhou Xiang only has an age difference.
