The Black Abyss Demon Emperor squinted his eyes.

"If I'm not mistaken, this magic staff is not one of the so-called Ten Great Holy Artifacts of humans, yet it can restrain my demonic qi."

"It seems this Taoist sect does have its tricks."

As he spoke, the Black Abyss Demon Emperor suddenly withdrew his demonic qi.

Upon seeing this, Zhou Yu and Gu Zifeng were both stunned.

What is the Black Abyss Demon Emperor planning?

The Black Abyss Demon Emperor let out a sinister laugh.

"My methods are unparalleled; using demonic qi is just a low-level technique."

"Next, let me show you the true power of my Dark Clan."

As he spoke, an overwhelming aura suddenly erupted from the Black Abyss Demon Emperor's body.

This aura did not come from that surging dark demonic qi.

It erupted from within him.

It was akin to the blood qi of human Body Refining Martial Artists.

However, the terrifying aura emanating from the Black Abyss Demon Emperor was far beyond anyone Zhou Yu had ever seen.

At this moment, Zhou Yu felt as if the Black Abyss Demon Emperor in front of him had transformed into a colossal beast.

Even if he stood there motionless, it induced an overwhelming sense of despair, utterly unshakeable.

Just then, the Black Abyss Demon Emperor flashed and punched directly at Gu Zifeng.

The powerful aura sweeping in directly tore the surrounding void apart.

Gu Zifeng's face changed dramatically; he was well aware that the strongest aspect of the Dark Demon Clan was their bodies.

It could be said that every member of the Demon Clan was a top-tier body refiner.

Moreover, they were far stronger than humans of the same realm.

With the Black Abyss Demon Emperor in close combat, he didn't dare to take it head-on.

Gu Zifeng immediately retreated explosively while activating the magic staff, casting a series of spells to block the Black Abyss Demon Emperor.

However, facing these spells, the Black Abyss Demon Emperor merely sneered, then punched again.

Where the punch reached, all spells were instantly destroyed.

There was no resistance at all.

Moreover, the speed of this punch was so swift it almost seemed to tear the void apart.

Gu Zifeng didn't have time to dodge and was hit directly.

Bang!

Gu Zifeng was sent flying like a cannonball.

Blood gushed from his mouth; in an instant, his whole body was a bloody mess.

With one punch, the Black Abyss Demon Emperor grievously wounded Gu Zifeng. He let out a sinister laugh and was about to strike again to finish him off completely.

However, just then, he suddenly sensed a crisis approaching.

The Black Abyss Demon Emperor's face turned grim as he turned his head to see a thunderbolt rushing toward him.

Simultaneously, Zhou Yu's furious shout echoed.

"Azure Lightning, Piercing Cloud Finger!"

Facing this thunderous onslaught, the Black Abyss Demon Emperor punched out immediately.

Boom!

In an instant, thunder exploded, and black qi permeated.

The Black Abyss Demon Emperor's punch directly shattered the thunderbolt with force.

However, a wound appeared on his fist.

From the wound flowed a stream of black blood.

The Black Abyss Demon Emperor's face was terrifyingly grim, his gaze locked onto Zhou Yu.

"Power Of Thunder!"

"That annoying presence I sensed earlier was precisely this Power Of Thunder."

"I didn't expect you to have mastered an Ancient Thunder Technique."

"I was planning to make you my servant."

"But since you have mastered the Thunder Technique, I cannot let you live; otherwise, you'll eventually become a major threat to my Dark Clan."

Indeed, Zhou Yu's use of the Power Of Thunder had a restraining effect on the Black Abyss Demon Emperor.

However, as Zhou Yu unleashed the Power Of Thunder, the Black Abyss Demon Emperor's desire to kill him exploded.

It was evident that the Black Abyss Demon Emperor detested the Power Of Thunder intensely and was deeply wary of it.

Zhou Yu, with his Ninth Grade King Realm cultivation, was able to injure the Black Abyss Demon Emperor—it was clearly all thanks to the Power Of Thunder!

Hearing the Black Abyss Demon Emperor's words, Zhou Yu remained silent.

He did not show any excitement for having injured the Black Abyss Demon Emperor.

Because he knew very well that the injury just now wasn't even a scratch to the Black Abyss Demon Emperor.

Even more frightening was that he could sense the Black Abyss Demon Emperor's killing intent toward him had multiplied.

Clearly, he had already been placed on the Black Abyss Demon Emperor's kill list.

Today, it's either you die or I live!

Zhou Yu didn't delay.

Now, his means of injuring the Black Abyss Demon Emperor were limited to the Five Thunders Technique and the still-concealed Heavenly Punishment Divine Thunder.

Therefore, he had to give it his all to find the opportunity to strike the Black Abyss Demon Emperor hard.

At this moment, within Zhou Yu's body, the Golden Core spun wildly, all True Yuan transforming into Power Of Thunder.

Simultaneously, the Power Of Thunder surged madly around Zhou Yu.

Above his head, thunderclouds churned, with clashes of thunder, as a thunderbolt as thick as an arm quietly formed.

Zhou Yu's gaze coldly locked onto the Black Abyss Demon Emperor, ready to unleash his most powerful strike at any moment.

Upon seeing this, the Black Abyss Demon Emperor smirked coldly.

"If your cultivation were higher, I might indeed fear you, but now, you're too weak."

"Let me show you my true cultivation!"

As he spoke, the Black Abyss Demon Emperor suddenly spread his arms and let out a sharp howl.

Runes appeared on his black flesh.

These runes began to flicker frantically.

Meanwhile, the overwhelming dark demonic qi was devoured voraciously by these runes.

The Black Abyss Demon Emperor's cultivation started to soar rapidly, reaching the peak of Ninth Grade Emperor Realm in just moments.

Next, the Black Abyss Demon Emperor opened his eyes to look at Zhou Yu.

A terrifying pressure emanated from him.

The enormous realm gap nearly suffocated Zhou Yu, causing his veins to bulge and blood vessels to swell.

Zhou Yu knew he couldn't wait any longer.

Otherwise, his aura would be thoroughly suppressed, and he might implode under the pressure.

Under this overwhelming evil might, Zhou Yu gave an all-out roar.

"Nine Heavens, Divine Thunder Break!!!!"
