From the many ancient texts Qin Fengming had studied, he naturally knew what a Ghost Crow was.
It should be said that this creature was a type of ghostly bird—a bizarre demonic bird that lived in places dense with Yin energy. It was born with a craving for corpse aura and could refine soul energy.
Its body was very small, about the size of an ordinary skylark, yet its cry was astonishingly loud.
Even a Ghost Crow at the tenth-level realm could produce a cry powerful enough to disturb the mind of an Integration stage cultivator and fill them with unease.
It also possessed something that made every cultivator tremble in terror: as long as a Ghost Crow reached the Profound Tier stage, a bizarre Yin energy known as Ghost Crow Nether Qi would be born within its body.
Ghost Crow Nether Qi was colorless and odorless, but its nature was that of extremely pure soul energy.
The reason it inspired fear in so many cultivators was that Ghost Crow Nether Qi could invade a cultivator's body and enter their sea of consciousness, devouring their soul energy without them realizing it.
Moreover, the devouring process would not be noticed by the cultivator at all.
Without special means of detection, it was virtually impossible to determine what was constantly reducing the soul energy within one's body.
Yet even after discovering that Ghost Crow Nether Qi had entered their sea of consciousness, ordinary cultivators—even Mahayana cultivators—would find it difficult to dispel it easily. They could only suppress it with secret arts.
Now that they had suddenly heard Blood Charm Saint Ancestor cry out the name Ghost Crow Nether Qi, no one present remained composed, even though all of them possessed the firm temperaments of Mahayana cultivators.
