บท 148: 146, Blood Clan and Beastman

Whether it be genuine Blood Clan vampires or humans who cultivate Bloody Glory, those of intermediate rank or below can advance their strength by devouring the life force of others, but vampires looking to ascend to high order can only rely on condensing a Blood Core to advance.

The various clans of the Blood Clan are born with different physical structures, and although they can also cross family names to practice other clans' secret techniques, the speed of such cross-training is inevitably slower than practicing their own clan's techniques, thus, even though there are vampires who practice different vampiric secret techniques, they are not mainstream.

Most of the Blood Clan only condense one Bloody Vortex, and like human knights, are ranked by the strength of their Blood Energy, not in the manner of Protagora's Bloody Glory where one advances each time a new Bloody Vortex is opened.
