The Holy King dug further into the ground, following the subtle signs of collapsed stone.
'They dug quite far down,' he thought as he kept digging.
When he reached a depth of 50 kilometers, his brows rose in surprise.
He had never been this far underground.
He wondered how far they had dug.
When he found the layer of Metal-Earth Stone, he started to get curious.
Why hadn't he dug down just to look at what was down below?
It was kind of interesting.
After reaching a depth of 70 kilometers, he stopped as he suddenly uncovered a black stream of mysterious material.
What was that?
Out of interest, he entered.
An incredible force immediately attacked his body, but his body was powerful enough to resist the force with some help from his Ether.
He descended further and further.
After another 30 kilometers, he stopped.
The force became stronger and stronger the deeper he went, and at this depth, not even he could remain for long.
