"Boom!"
Outside the valley.
Amidst the dazzling light that shined to the extreme and the background of fierce, burning flames, a Demon King that resembled a bear-man - yet was a massive twenty meters tall - ran for its life in terror, using every ounce of its strength.
Fire engulfed its body, burning its fur.
Some parts were visibly charred.
Yet, at this moment, it couldn't care less, seeking only to flee the valley as fast as possible.
However, before it could fully escape from the mouth of the valley, behind it, a tunnel suddenly appeared in the valley that was almost swallowed by fierce flames.
A tunnel with hardly any flames.
In the valley that had become a sea of fire, this was nothing short of a miracle.
The very next second, the ground cracked apart.
From within the cataclysm of the fire sea, the tunnel erupted with a violent hurricane, a sonic boom, and even tore a gully in the ground.
