The gravity on the seventh floor of the Void Shattering Tower was three times that of Blue Star.
Correspondingly, the soil was far denser than that of Blue Star.
Not to mention that the seventh floor of the Void Shattering Tower was a world of ice and snow, its ground covered by a thick layer of ice.
This made the ground even harder and more solid.
Ordinary Second-Order Metahumans could not even break through the surface.
But for Ninth-Order experts like Rio and the others, it was no problem at all.
In just a few minutes, they had excavated more than half of the entire area, which spanned over a hundred square kilometers.
Some of the pits they had dug were even dozens of meters deep.
"Warren, how many Void Stones have you dug up over there?"

There should have been at least five hundred thousand Void Stones, yet they were short by more than half!
"Maybe something went wrong with my Mental Strength sensing."
Warren, the only Law Saint among them, replied somewhat hesitantly, "The Void Stones excavated
