Chapter 560: Dark Demon Lord

The shadowy figure of the demonic mist instantly swelled several times in size.

It stood before the crowd like a small hill.

If the current shadowy figure of the demonic mist were compared to my lord,

then the Purple Lightning Lei Xiong at this moment would be a newborn infant.

Not only in size, but also in that heart-pounding, terrifying aura.

At the same time—

The eldest of the Five Heroes now wore an expression of pain on his face.

The hand he had just used to condense the pitch-black mist

was now entirely infected by the black qi.

"How could this be? The Demon Emperor back then..."

The eldest of the Five Heroes had barely uttered a few words before the pain dragged his thoughts back.

He could only use his magical power to block his arm, preventing that demonic qi from rushing into his body.

Suddenly, the black mist demon shadow, which had just stabilized its form, emitted a piercing sound.

"Hahaha!"

"I, the Dark Demon Lord, am free!"

"All living beings!"

"Tremble!"

As his voice sounded,

an incredibly thick wave of demonic qi surged outward from him in all directions.
