On his journey to Fox Mound, Lin Yi saw some cultivators who had been deceived by the foxes. They appeared soulless, like walking corpses.
From this, it could be inferred that these cultivators buried in the mounds were probably ones who had been deceived.
The fox is a species highly adept at illusions. This is the origin of fox spirits who, after becoming sentient, transform into women to absorb male energy.
Compared with Hehuan Sect's method of absorbing cultivation levels through intercourse, the fox clan seemed to be after both lives and possessions. They not only coveted the cultivator's yang energy, but also devoured their souls.
Inside the Fox Mound, he noticed the presence of some foxes, accompanied by the sound of crisp laughter. In these deserted mounds, it seemed particularly eerie, giving a discomforting feeling.
