On a fel planet on the outskirts of Argus, the demons stared in terror at the enormous fireball rising in the distance.
The enormous fireball was blinding, like a dazzling sun.
Even with their powerful fire resistance, the demons still felt discomfort in their eyes.
As the fireball rose, vast quantities of dust also surged into the sky, forming an enormous cloud of fire that resembled molten lava.
Soon, more dust obscured the fiery cloud.
The dust spread across the sky, forming a mushroom-shaped cloud.
This seemingly world-destroying attack reminded some demons of Burning Legion Warships bombarding native inhabitants.
But the destruction caused by Burning Legion Warships fell far short of this!
A mushroom cloud two or three thousand meters high, with complete destruction across a few square kilometers, was their limit.
The massive explosion before them, however, produced a mushroom cloud tens of thousands of meters high.
Even though they were over a hundred kilometers from the edge of the blast zone.
They could still feel the searing winds sweeping past.
A vast area within a fifty-kilometer radius had already been completely destroyed by that blazing fireball.
The vast majority of demons in that area certainly could not have survived the explosion.
Their supposedly powerful fire resistance was only useful against flames at normal temperatures.
Yet within the area engulfed by that fireball, even felsteel had melted!
Weapons and armor forged from felsteel were resistant to high temperatures.
Even heating them in blazing lava could not soften them.
If that fireball could melt a heat-resistant metal like felsteel, it could burn demons' bodies to ashes.
At the sight of the mangled Infernal Constructs struggling to stand.
The demons watching from afar were not surprised.
It was only because these fellows' bodies were made of fel rock.
And they were
