Before Spirit Medicine Immortal Aunt's words had even faded, strands of pitch-black patterns appeared across the surface of the pale skeleton beneath her numb, tattered robes.
They flowed downward like trickling streams, converging at the ends of her bones and forming droplets of pitch-black liquid.
The instant these liquids appeared, both Su Yuan and Guiyuan felt an intense, overwhelming sense of danger.
