The purple glow emanating from the black dot pierced through the entire ore vein.
As time ticked by.
The spiritual energy within the entire mine grew increasingly dense, and the ground began to tremble slightly.
Shen Feng stood still, feeling the changes within the entire vein, and his heart brimmed with an indescribable joy. Now that the black dot had devoured the purple Original Blood, it had acquired an unbelievably heaven-defying ability. With countless mined-out veins in the Immortal Realm, it meant he had an inexhaustible source of Spirit Stones.
About tens of minutes later.
The black dot, roughly the size of a fist, above Shen Feng's head began to slowly stop spinning, and the purple light radiating from it also gradually faded.
When the black dot completely ceased rotating and rapidly shrank back to its original size, it rushed into Shen Feng's body and finally returned to his Dantian.
At this moment.
