The shadow fragments trapped within the rock cage were not spared either, one by one they were blasted into fumes by the lightning and disappeared from the ground level.
The rock cage itself, however, survived thanks to its decent resistance to thunder and lightning energy...

Since thunder and lightning magic was so effective, there was no need for him to be as cautious as he had been before.
Noland Lee issued a command to the five Ground Drilling Mechanisms underground to drill full-force.
