Nether River Mirror

A hint of apprehension appeared in the Demon King's eyes.

This was Formation that had sealed him away for hundreds of years.

Nature is extraordinary.

As the Formation operated, a series of sounds, like gears meshing and turning, rang out.

Sizzle! Sizzle! Sizzle!

The Chains binding the Demon King were tightened one by one, and the Demon King's enormous body was also pulled up.

These Chains were connected to the meridians in his body, and they caused him great pain when they were pulled.

His movements were also restricted at this moment.

Anger flashed in his eyes.

He's Demon King, how could he possibly submit to humans?

Roar!

The Demon King roared, and terrifying power emanated from his body, as if it would tear the humans before him to shreds.

A tremendous force also fell upon those Chains.

The Chains rattled and jingled.

The array masters casting spells wore expressions of pain, their hands forming hand seals one after another. However, under the Demon King's fierce resistance, each iron chain felt as heavy as a thousand pounds, making it extremely difficult to control.

Some of the weaker array masters had flushed red faces and were on the verge of collapsing.

Upon seeing this scene, Du Zian's eyes flashed with a cold light. He stepped forward, his hands quickly forming hand seals, and streams of Source Force flowed from his body.

It spread rapidly like a tangible force, arriving at the Formation almost instantly.

These forces formed purple runes that spread rapidly toward the chains, attaching themselves to each chain.

With the appearance of these purple runes.

The chains seemed to be infused with some kind of power.

Extremely heavy forces fell upon the Demon King.

The Demon King, who had been struggling violently, stopped and stared at Du Zian with eyes full of anger.

Without this Formation, he could swallow even ten Du Zian.

However, under this Formation, he was no match for Du Zian at all.

"Damn it!" the Demon King roared, his eyes filled with barely concealed rage.

Du Zian's eyes were cold.

"Under this Formation, you still dare to act recklessly?"

The Demon King's eyes were filled with rage.

"You're just relying on the methods of your ancestors. If you're really capable, then fight me one-on-one and see if I can kill you!" the Demon King roared.

Du Zian sneered.

"Unfortunately, you didn't have that chance!"

The Demon King sneered, "Do you really think that's all I've got?"

Black Qi appeared on the surface of his skin.

Within this Black Qi, it seemed as if vengeful spirits were roaring, uttering howls.

As these sounds were heard, some of the chains trembled continuously.

Cracks appeared on the surface of the iron chain.

Du Zian's eyes showed a hint of seriousness when he saw this scene.

He knew very well that the Formation had also begun to decline over the centuries.

In some places, there are certain problems.

More importantly, the Demon King has been searching for a way to break the Formation all these years.

He also destroyed the foundations of some Formation and altered the terrain of some places.

This scenario was within Du Zian's expectations.

The Demon King struggled incessantly, as if trying to break free from those iron chains.

Du Zian took a deep breath and stretched out one hand forward, releasing streams of azure power.

Buzz!

It was as if a deity had descended upon the Formation.

The deity was surrounded by divine light, as if he possessed endless power. He held Long Sword in his hand and slowly approached the Demon King.

With the appearance of this deity, the entire Formation was enveloped in a layer of golden light.

The Demon King's power continued to wane, and his eyes were filled with resentment.

He knew very well that this was the Formation Spirit.

As long as it exists, it is impossible for me to break the Formation.

"Damn it, so many years have passed, and it's still haunting us!" The Demon King roared angrily.

All that could be seen was the deity chanting incantations.

The Long Sword in his hand pierced into the Demon King's body.

The Demon King seemed to be imprisoned by something, unable to move at all. No matter how much he struggled, he could not break free from the binding force.

Du Zian secretly breathed a sigh of relief; thankfully, the Formation Spirit was there.

Otherwise, with his power, he would never be able to suppress the Demon King.

With a wave of his hand, he sent out a message.

Not long after, Ji Xi and the others walked in. When they saw the Demon King who had been suppressed, their eyes were filled with indifference.

The Demon King has always been a thorn in their side.

They've been trying to eradicate them for so many years.

However, the Demon King has strong vitality and outstanding abilities, so even if they wanted to kill him, it wouldn't be so easy.

"Demon King, you have been imprisoned for hundreds of years, and during these hundreds of years you have never given up, constantly looking for opportunities, and even breaking down the defenses of the students within our academy, turning them into your subordinates!"

"Today, we've finally found a way to deal with you!"

"You've been rampant for so long, it's time you paid the price!"

The Demon King's eyes held a hint of mockery.

"You think you can kill me with just a Fourth Tier Martial Artist? How laughable!"

Ji Xi ignored him, and a bronze mirror appeared in the palm of his hand.

The surface of the bronze mirror has patterns that resemble water ripples.

Around the bronze mirror are various kinds of Nether Beast, which look quite peculiar.

With the appearance of the bronze mirror, the surrounding temperature seemed to drop considerably, and streams of Netherworld Power emanated from the mirror.

Lin Mu stared at the bronze mirror, a hint of surprise in his eyes.

If he hadn't seen it with his own eyes, he would have thought that the bronze mirror was something from the Netherworld.

But how could something from the Netherworld appear in the Mortal World?

Ji Xi chanted incantations as his Source Force and Mental Power continuously flowed into the bronze mirror.

The patterns on the surface of the bronze mirror revealed streaks of light and a faint, dark luster.

The bronze mirror flew up at this moment, rapidly expanding until it formed a plane resembling a passageway.

Within the plane, streams of extremely powerful Netherworld Power emanated.

The figures of Di Yan and others then appeared.

They stood atop a valley, their eyes fixed on the Demon King before them, exuding a chilling aura.

Di Yan himself is the leader of the Earth Soul Clan and possesses extremely strong power.

The moment he saw the Demon King, he also revealed his true form, and an aura no less powerful than that of the Demon King emanated from him.

The tens of thousands of soldiers behind him roared, and waves of fighting spirit entered Di Yan's body.

Di Yan's size increased dramatically again, and a terrifying aura spread out.

It is no exaggeration to say that even if the Demon King were at his peak, he would still find these Nether Beast extremely troublesome.

Because the Netherworld Power they wield can inflict tremendous damage on him.

However, he has been sealed away for hundreds of years, and his combat power is far less than before.

He was also somewhat intimidated by the current situation.

After all, these Nether Beasts in front of him could really kill him.

But as Demon King, he wouldn't show his fear even if he was a little scared. His eyes were full of coldness, and he uttered a rebuking sound.

"A mere Nether Beast dares to dream of killing me? How laughable!"

Di Yan's eyes were filled with a cold expression.

"Nether Beast are the nemesis of all living beings in the Mortal World, and Demon are no exception. If you're truly not afraid, we can have a spar. But I guarantee you'll die by my hand!!"
