Start slaying demons from the proficiency panel.

hum!

With a sonic boom, a figure shot out from the pit, trailing a black tail, and headed straight for the Black Demon Ancestor.

Ning Xiu's clothes had been destroyed in the previous attack, and now, under the sky, his strong and streamlined muscles were on full display, each one possessing terrifying explosive power.

Following the Black Demon Ancestor, Ning Xiu kept punching with both fists, so fast that it created countless afterimages.

Every punch landed squarely, generating the fifth level of power, while crimson internal energy surged forth, sweeping over a thousand miles with the force of the punches, enveloping the entire body of the Black Demon Clan and scorching them.

The power of the Burning Heaven Scripture far surpasses that of the Burning Sun Taiyao Scripture. Even without relying on the power of the Great Annihilation Spear Technique, Ning Xiu could still suppress a Dragon Elephant Upper Realm cultivator in a one-on-one situation.

The dragon breath that the Black Demon Ancestor just unleashed seemed fierce and extremely destructive, but to Ning Xiu, it was nothing more than a child's game.

Under the barrage of punches, large patches of the Black Demon Ancestor's dragon scales fell off and burst, spraying blood from beneath them, leaving him covered in numerous wounds.

Ning Xiu seized the opportunity and thrust his twin spears into the chest of the Black Demon Ancestor. The two national treasures easily pierced through the Black Demon Ancestor's chest. The purple dragon let out a mournful cry and then fell to the ground, struggling to get up.

"Is this guy really at the Dragon Elephant Upper Realm?!" The Black Demon Ancestor looked at Ning Xiu, his heart filled with shock.

This Purple Dragon Clan member was just a body he casually inhabited; his death was nothing to the Black Demon Ancestor.

If he's willing, with a little effort, he can still acquire a body at the Dragon-Elephant Upper Realm.

In this era of the Profound Yin Domain, everything in the world has changed dramatically. For the Black Demon Ancestor, this is a qualitative change, as he now possesses a completely new power that he had never mastered before.

Even now, after witnessing Ning Xiu's display of strength, he still couldn't help but feel apprehensive. The Black Demon Ancestor was confident that he had the deepest understanding of the Dragon Elephant Upper Realm.

But Ning Xiu's performance far exceeded his expectations. The strength this guy displayed was no longer just that of the Upper Dragon Elephant Realm.

"Yang Yao has not yet arrived. No one is allowed to enter the inner realm during this period, or it will ruin my plan. This guy must die." The Black Demon Ancestor thought viciously. "It is too early to open the Xuan Yin Gate now. I am not sure about the situation there. However, if I can kill this guy, it is not impossible to pay some uncontrollable price."

Thinking this, the Black Demon Ancestor instantly relinquished control over the Purple Dragon Clan member.

At the same time, in Yaotuo Prefecture and several surrounding prefectures, a beam of black light shot out from underground and soared into the sky.

Then they converged together in the high sky, forming a black sphere.

"What else do you want to do? You're asking for death."

"Me?" The Purple Dragon Clan member was somewhat confused.

Upon seeing this, Ning Xiu immediately rebuked the Purple Dragon Clan member and forcefully hurled the Candle Dragon in his hand. Using the Great Annihilation Spear Technique, he blasted the opponent's head apart in one fell swoop.

However, the death of the Purple Dragon Clan's Dragon Elephant King did not cause any changes; the black light in the sky continued to persist, converging with each other.

In just a few breaths, the black sphere suddenly elongated, opening a crack directly in the sky.

A chilling gust of wind blew out from the other end of the crevice, and the whole world seemed to fall silent because of it.

Looking into the darkness beyond the crack, Ning Xiu had a strange premonition. He could sense a powerful threat approaching.

"Quack quack!"

In an instant, all the immortal creatures growing on the Yin Tree within a radius of ten thousand miles in Yaotuo Prefecture seemed to sense something and began to emit eerie laughter in unison.

Laughter echoed throughout the entire Yata region, sending chills down one's spine.

"This is bad! The boundary has been opened. Kid, you need to be careful. Something from outside the boundary might break in. Those are dangers you can't even imagine. Sometimes, if you encounter something strong, even you can only become food." Emperor Zhenyang warned him.

Ning Xiu nodded. Even without the True Yang Emperor's reminder, he sensed that something was wrong.

The Demon Ancestor must have been up to no good in secret. Seeing that he couldn't defeat him, he was trying to lure in an even more powerful enemy to deal with him.

In the darkness of the crevice, an eye suddenly opened, its blood-red pupil staring at Ning Xiu with supreme killing intent.

In that instant, Ning Xiu felt as if his body had fallen into an ice cave, so cold that he could hardly move. It felt as if countless sharp knives were constantly slicing and tearing through every inch of his internal organs.

"Ugh!" Ning Xiu's expression changed drastically, and he suddenly spat out a mouthful of blood, which was mixed with a lot of bits of flesh.

If it weren't just an eye, but if the owner of that eye had personally descended, Ning Xiu would have died instantly without any resistance.

"What is that thing?!" Ning Xiu asked the True Yang Emperor in disbelief, clutching his aching chest.

"I don't know either. After I became an emperor, I was immediately confronted by the Yin Tide. I didn't even have time to break through the void and go beyond the boundary to take a look," Emperor Zhenyang said regretfully.

The sky rift created by the Black Demon Ancestor was over 500 feet long, which was quite large even in the sky.

Even so, it was only enough to barely see one eye on the other side of the gap, enough to imagine just how enormous the thing itself was.

Just then, a figure suddenly crawled over from the other side of the crack.

It was a monster that looked very much like a human, but was pale green all over, had horns on its head, and a pair of bat-like wings on its back.

It has three eyes but no mouth; its chin is covered with wriggling tentacles, making it look very creepy.

"They've come out! The extraterrestrial demons!" The Black Demon Ancestor, hidden underground, couldn't help but shout excitedly upon seeing this scene.

The reason he was wary of opening the Xuan Yin Gate was because he was wary of these beings who only lived outside the realm. These beings, known as the Extraterrestrial Demons, were born from the Primordial Yin Qi.

By nature, they are brutal, ferocious, and bloodthirsty. For them, the only things they can do are destruction and killing. In addition, the extraterrestrial demons have been extremely powerful since their birth and have always been regarded as an 'extremely evil threat'.

While the extraterrestrial demons are powerful and terrifying, they do not possess the ability to break through boundaries, so they can only wander outside the boundaries.

Now, the Black Demon Ancestor has gone so far as to destroy the realm and open a crack, giving the extraterrestrial demons an opportunity to take advantage of it. Before long, one of them was attracted.

"Hehehe..." Flying out from the crack, floating high in the sky and looking down at the earth, the extraterrestrial demon opened its arms and let out a strange laugh.

Its laughter didn't come from its body; rather, it sounded as if it appeared out of thin air.

It was a kind of early celebration of being able to enjoy the slaughter, an unparalleled joy of arriving in a certain territory.

At this moment, the laughing extraterrestrial demon turned its gaze to Ning Xiu, the only surviving being within a thousand miles.

Mockery, ridicule, murderous intent... all sorts of looks were directed at Ning Xiu, making him look like a butcher watching his livestock, ready to slaughter it at any moment.

The crack didn't last long. Just as the second extraterrestrial demon was about to crawl in, the crack suddenly contracted and disappeared.

The demon only had time to let out a scream before its body was cleaved in two.

Shattering the void is not something that can be done easily, and even those who can do it cannot maintain the opened realm indefinitely.

Although the Black Demon Ancestor was able to open the boundary, he could only maintain it for a short time before it would quickly return to its original state.

However, the fact that a demon from beyond the realm could sneak in to deal with Ning Xiu was exactly what the Black Demon Ancestor wanted most, and his goal had been achieved.

Compared to the owner of that eye, this extraterrestrial demon seemed as insignificant as an ant, but in reality, if you remove the giant eye as a reference point, the extraterrestrial demon was actually a behemoth.

It was a full twenty feet tall, and even Ning Xiu, the Six-Armed Great Black Heaven, seemed insignificant in its presence.

But this was not what Ning Xiu cared about. As the crack disappeared and the suppression of that eye was gone, the enormous pressure Ning Xiu was under immediately eased.

He wiped the blood from the corner of his mouth and looked carefully at the demon who had sneaked in, his heart filled with caution.

He couldn't see through it; he couldn't even fathom the true strength of this celestial demon.

"Be careful. Extraterrestrial demons possess terrifying strength from birth. In addition, they roam outside the realm for many years, absorbing primordial yin energy. Even without cultivation, their strength will increase wildly. They are not easy to deal with. Do not underestimate them," the True Yang Emperor warned.

"Gah!"

The extraterrestrial demon tilted its head and let out a strange cry. The next moment, its figure disappeared from the spot and reappeared behind Ning Xiu.

The extraterrestrial demons were extremely interested in this human, and decided to thoroughly mock him before finally slaughtering him.

Ning Xiu's face darkened, and his protective golden bell instantly activated. He turned around and unleashed the Great Annihilation Spear Technique.

Faced with this unknown enemy whom we have never encountered before, we can no longer hold back. We must strive to kill them with one blow, leaving them unable to react in time.

The Great Annihilation Spear Technique was unleashed at close range, causing even the air to distort slightly.

The extraterrestrial demon reached out to grab Ning Xiu's spear, but before its hand even touched the spearhead, it crumbled, its skin, bones, and flesh turning into fragments that scattered everywhere.

"Gah!" The extraterrestrial demon cried out in agony. With a flap of its wings, it was left as a blur, its true form already more than ten feet away.

"What?!" Ning Xiu was slightly startled. He knew all too well how powerful his Great Annihilation Spear Technique was.

Logically speaking, when the Great Annihilation Spear Technique is unleashed, no living being should be able to escape its range.

But this extraterrestrial demon actually managed to do it; putting everything else aside, its speed was definitely far superior to Ning Xiu's.

Seeing that Ning Xiu had crippled the extraterrestrial demon's hand with a single spear thrust, even the Black Demon Ancestor, who had been secretly watching, was stunned.

You have to understand that the extraterrestrial demons are a troublesome existence even for him now. If he weren't so confident that he could control them, he would have opened the Xuan Yin Gate long ago.

But now, a demon from beyond the realm is no match for Ning Xiu. How can he accept this?

No matter what, the Black Demon Ancestor was someone who survived from the era of the Ten Demon Emperors and the True Yang Emperor, so he naturally had many trump cards and methods.

But now, a young human has easily accomplished what he could not.

This was something the Black Demon Ancestor found very hard to accept. What was the origin of this human Demon Subduer?

Could he be the reincarnation of some great emperor?

The extraterrestrial demon was injured, and its hatred for Ning Xiu surged. Extraterrestrial demons were evil creatures that knew no fear, only anger and slaughter.

For them, nothing was more important than revenge and slaughter.

The extraterrestrial demon felt no fear at all that Ning Xiu had injured its arm; instead, it became even more determined to kill Ning Xiu and devour him.

"We absolutely cannot let this guy escape, or there will truly be widespread suffering." Emperor Zhenyang looked at the extraterrestrial demon, whose arm had been severed, but was now rapidly regenerating and finally returning to its original state.

This healing ability is simply heaven-defying; even a powerful expert at the upper level of the Dragon Elephant Realm cannot achieve this level.

Ning Xiu wielded the Golden Crow, Candle Dragon, and Yin Willow spears without flinching. Since he had managed to sever one of the extraterrestrial demon's arms this time, he could take its life with the next spear.

In an instant, Ning Xiu moved.

Two golden cicadas appeared beneath his feet, lifting his body and instantly disappearing from the spot.

Its speed was so fast that even the Black Demon Ancestor, who was secretly watching the battle, could not catch it.

Supernatural Power: Spring and Autumn Cicada Step!

Ning Xiu seemed to have traversed space, appearing directly in front of the extraterrestrial demon, his six arms wielding three spears, which he thrust out simultaneously.

All three spears emitted a black light with an aura of annihilation, completely enveloping the extraterrestrial demon.

Having experienced the power of the Great Annihilation Spear Technique once, the extraterrestrial demons became somewhat wary of Ning Xiu, who was much smaller than themselves.

When Ning Xiu thrust his spear again, the extraterrestrial demon did not choose to immediately freeze, but instead dodged to the side and then grabbed at Ning Xiu's lower body with a palm.

The force of this claw strike was terrifying, even distorting the air itself. When it struck Ning Xiu's protective golden bell, the bell shattered instantly, unable to withstand the power of the attack.

Seeing that its hand had caught Ning Xiu, the extraterrestrial demon was smug. However, as the figure of Ning Xiu it had caught slowly disappeared, the extraterrestrial demon realized that it had caught an afterimage.

puff!puff!puff!
