The thunder light dissipated, leaving behind countless demons, seas of blood, dried corpses, mats of flesh mud, and various trees and vegetation all turned into dust.
Even the mountain peaks and rocks were blasted inside and out by the scorching high temperature of the Pure Yang Thunder, creating crisscrossing cracks on the surfaces of the three mountain peaks surrounding the valley, leaving their surfaces carbonized.
Looking around, the sky is filled with ash like gray-black snowflakes, scattered everywhere. The entire valley has turned charcoal black.
A bright earth-yellow regular hexagonal crystal stands out conspicuously against the dark background.
This crystal was left behind by the Iron Horn King. Being a Four Tribulation Great Demon, despite being obliterated in both form and spirit, it left behind a demon core under the purification of Pure Yang Thunder.
