"What is this thing, so eerie?" Lin Tian wondered aloud. Although he had seen the peculiarities of Gu arts, those were meant to deal with ordinary people, while the black aura before him could affect Blood Clan members, even those at the lord level.
Zhang Lingyu carefully observed the black aura in the bottle for a while before saying, "This should be a secret technique of the Blood Clan. If I'm not mistaken, the caster is also a member of the Blood Clan. They used their own blood along with tiny insects to concoct Blood Worms, which are living organisms."
"After being hit by this secret technique, the Blood Worms will attach to the victim, hiding within the bloodstream. When the Blood Worm is dormant, it masquerades as Blood Clan blood, making it nearly indistinguishable from the real thing. Since Blood Worms spend most of their time dormant, even if someone suspects and investigates, they won't find anything."
