Li Muyang was no stranger to the Soulless.
This was a special kind of mystical disease. Little Wild Grass was also bought by the Demon Cultivators and taken to Black Cloud Fort because of this disease.
Those afflicted by this disease are said to hear voices from another world, gradually lose their sanity and consciousness after nightfall, and cyclically become bloodthirsty and brutal.
In the end, they fully succumb to madness and transform into beast-like monsters that roam the wilderness and attack living beings.
For ordinary people, this disease is a calamity.
But for Demon Cultivators, these sufferers are excellent materials.
A special substance secretes in the blood of the Soulless. Once a certain amount of this substance accumulates, drawing the demonic blood from them for Artifact Refining or Cultivation is extremely beneficial.
During his childhood, Little Wild Grass was regularly bled by the Demon Cultivators in the hinterland.
