While it was also the power of thunder, the black thunder that manifested as the ancient ferocious beast, a wolf dragon, was not the ultimate heat and destruction, but instead, pulverization.
In the face of such immense power, where space shattered and laws dissipated, even Jack Clark sustained light injuries, despite his body being more formidable than the Boundary Wall of the plane.
Jack Clark sighed lightly, "As expected of the power of the Mythical Heaven Tribulation, it truly must not be underestimated."
As he spoke, the cracks on his body disappeared at a visible rate, recovering in the blink of an eye; then Jack Clark focused on the rampaging void before him.
There, a black lightning several meters long serpentine flashed, exuding pure energy of the Laws' Origin.
The moment Jack Clark grasped that black thunder, his entire being was enveloped in dense black lightning, and simultaneously, the golden vertical pupils that manifested the law of the void entered his body.
