As for those flashy bat wings...
They symbolize the Blood Vulture Clan!
Each of the seven vampire clans possesses its own unique power. Although other vampires have delicate and small wings that seem more like ornaments, to the haughty Blood Vultures, these are at best used for gliding or fluttering hopelessly.
Only the sufficiently broad and powerful bat wings of the Blood Vulture Clan can be considered to truly control the sky.
"So cool."
For a moment, Murphy felt a bit envious.
Although he was also a formal member of the Blood Vulture Clan, his strength was not yet at the level required to form blood wings. Cui Si had told him about this; forming blood wings only started after achieving the "Black Iron Body".
Right now, he was just a weak professional, still some distance from entering that domain.
