Dark Bone Dragons, level four dark-attribute spirit beasts, inherently evil, with a preference for living in groups. Originally dwelling on Demon Island at the southernmost tip of the Profound Cyan Continent, they were discovered by Mo Yue by chance and brought back to the Blood Sect using Canghen Crystal, kept at the darkest depths of Luoji Mountain. Though not individually powerful, when gathered, their destructive force is astonishing. Remembering the time when nearly clashing head-on with the forces of Demon Island, Mo Yue felt a lingering fear.
"Sect Leader, it seems the Dark Bone Dragons have been startled by something, otherwise, they wouldn't make such sounds."
Ghost Howl lowered his head and said.
"It's not fright, it's a summoning."
