Mining, Black Yama King

Lin Feng surveyed his surroundings. This place was somewhat dim.

Once one entered the ore vein, they could no longer come and go as they pleased.

They had to wait until six hours had passed each day before they could leave the ore vein.

Moreover, their Storage Bags had to be inspected by a magical artifact to ensure that no Immortal Spirit Stones had been secretly hidden inside!
