As we all know, angels and demons are at odds. And many times, when angels meet demons, they are more vulnerable. In the future, in order to avoid the harm of the devil, angels will have a pair of wings, but the devil does not. So the devil can't catch angels flying in the sky.
Second, in order to distinguish it from ordinary people.
Angels are similar to most human beings, but if there is really nothing to distinguish, how can the world believe in angels? So I gave the angel a pair of wings. Since others don't believe in angel knowledge, show them your wings.
Angels will fly freely in the sky, giving wings a sense of freedom. Humans have been pursuing their true freedom, and they have all the wishes given by angels.
Third, it is to work better and not be disturbed by external forces.
Cupid is the god of love. He is an angel like a child. He is not tall enough. If he has no wings, how can he shoot Cupid's arrow at those adults?
Because of the wings, flying in the air, the field of vision is wide enough, and Cupid's arrow can shoot very accurately. Increase the efficiency and accuracy of work, otherwise a small man like Cupid, let alone archery, will not be abducted even if he is sitting in a stream of people.
