Unknown Pure Aura

Only a few zhangs deep beneath the large pit, there was an expanse of grey and white fog, yet amidst it were intermingled some lustrous black strands, each as thin as a strand of hair, remaining perfectly still regardless of the churning fog around them, giving off an exceedingly bizarre feeling.
