Just as the mortal realm has coal sellers whose "faces are covered in dust and ash, and their ten fingers are black," the Immortal Realm also has immortal stone miners whose "temples are gray and ten fingers are black."
Those cultivators whom the immortals called mine slaves mostly had gray temples.
Scars of all sizes crisscrossed their bodies, and their clothes were in tatters.
There were male cultivators, and female cultivators as well.
It was just that the number of male cultivators was somewhat greater.
Unlike the other immortal stone mineral veins in the Immortal Realm, cultivation was impossible within Frost Moon Divine Valley.
Naturally, it was also impossible to use Immortal Energy to mine, and they could only rely on human labor.
The mined immortal stones also had to be carried out load by load.
Long-term labor had bent the backs of the mine slaves.
It had also made them utterly numb.
