Chen Yuan gently took a step forward.
"Boom!"
The entire world instantly flipped, and an overwhelming netherworld fire enveloped the space within a hundred feet radius.
These black flames seemed to come from hell, and just a touch was enough to cause a Heavenly Monarch and even a Quasi-star Lord to fall directly.
He withdrew his foot, and the netherworld fire suddenly retracted.
Chen Yuan felt a slight hint of astonishment in his heart.
The Netherworld Profound Crystal was indeed a saint material, possessing an autonomous protective awareness, but this was not Chen Yuan's first encounter with it.
In a previous lifetime, he had seen a Netherworld Profound Crystal as tall as an adult in a restricted area, and the power of that netherworld fire was terrifying beyond measure.
But it should be known that after being refined, the Netherworld Profound Crystal has no autonomous attack awareness, at most a potential instinct.
