He Wuhen saw from the reconnaissance map that the light from the Thousand Sword Formation fell vertically from the air and extended to the underground a hundred feet deep.

The colorful light enveloped the black tomb, penetrated the ground, and condensed into a light shield barrier about a hundred feet deep and thousands of feet in radius.

This light shield is condensed by the full power of the Thousand Sword Array, containing an unparalleled suppression of pressure, suppressing the Black Evil Demon King underground for a hundred years.

When the Black Evil Demon King is silent on weekdays, this circle of colorful light shields is hidden, and it will only be revealed when the Black Evil Demon King bursts out his power and wants to break through the seal.

There was a huge black shadow, dormant deep in the ground, lying quietly, without moving.

The black shadow was as big as a palace, showing the appearance of a huge monster.

The huge monster had huge arms, as thick as his legs, and almost occupied half of his body size.

Even more, there were spikes on its arms, showing unparalleled power and violence.

After a closer look, I found that this huge monster was condensed by rolling black fog.

Seeing this scene, He Wuhen realized that the monster formed by the black fog was the demon shadow of the Black Evil Demon King.

The Black Demon King had a thick iron chain tied to his hands and feet, tying him.

The iron chain is hundreds of feet long and as thick as a house. One end is tied with the Black Demon King and the other end is connected with the colorful light shield of the Thousand Sword Array.

These four iron chains are not ordinary things, they must be top treasures in mysterious weapons, so that they can trap and suppress powerful people like the Black Demon King.

However, He Wuhen keenly observed through the reconnaissance map that two iron chains tied with the hands of the Black Evil Demon King were actually broken from the middle.

The two iron chains were broken, and the hands of the Black Demon King lost their restraints, and the sealing power became much weaker, so he had the opportunity to attack the formation blockade.

He Wuhen recalled Baili Bing's previous words again, and guessed that these two iron chains might have been destroyed.

"But, the sect of the Black Demon King had been wiped out back then. Who would secretly take action to help this bloody and sinful demon king?"

This question appeared in his mind, and he couldn't find the answer after thinking for a long time.

At the same time, there was another more important question that lingered in his mind, making him a little confused.

There were dozens of disciples guarding the mountains around the Thousand Sword Formation. Even if the strong Wuzong sect broke into the deep valley, it would never be possible to bypass the surveillance of those disciples.

Even if there are powerful Wuzong people who are powerful in martial arts, they can luckily hide from the investigations of those disciples, but how can they destroy the Thousand Sword Formation after entering this deep valley?

After all, there are more than a dozen powerful Wuzong people around the Thousand Sword Formation, and no movement can be hidden from them.

With these two questions hidden in his heart, He Wuhen fell into deep thought.

The bright moon climbed into the sky, sprinkling the cold moonlight, but it could not reflect into the deep valley.

The Thousand Sword Formation has calmed down for a long time, and the hearts of many powerful Wushu sects have also been much more stable.

He Wuhen sat cross-legged on a big rock, staring at the Thousand Sword Formation with his eyes burningly, and was still guessing various possibilities in his heart.

At this moment, the Thousand Sword Formation suddenly burst out with dazzling light, and the colorful light shone brightly in the deep valley.

A powerful and long roar came from the depths of the ground, awakening many powerful Wusect masters. They all seemed to be facing a great enemy, with a serious expression.

"Boom! Boom! Boom!"

It was like the sound of muffled thunder erupting, and it sounded deep in the ground.

The earth in a radius of several miles was trembling violently, the big stones on the ground jumped and rolled continuously, and the ground cracked into dense cracks, like spider webs.

The Thousand Sword Formation was shaking violently, and the Thousand Swords burst into sword light, trembling constantly, making waves of wailing sounds.

All the powerful men of the Wuzong realized that the Black Evil Demon King was attacking the Thousand Sword Formation again.

So everyone quickly used the magic-suppressing fingering method to transport the Yuan power to the Thousand Sword Formation and superimpose the sealing power.

He Wuhen immediately stretched out his hands, made a sword finger, used the magic-suppressing finger technique, and drove the powerful Yuan power into the Thousand Sword Formation.

At the same time, he did not forget to open the investigation map and explore the depths of the ground.

I saw that a hundred feet deep underground, the huge black monster was holding up his huge arms and pounding the colorful light shield hard.

Without iron chains, the arms of the Black Demon King burst out with earth-shaking power. Every time he hit, he could tremble violently, and he was on the verge of breaking.

"boom!"

The Black Demon King raised his arms and slammed hard at the barrier of the colorful light shield, making a muffled sound.

The earth suddenly cracked countless huge cracks, and endless gravel and dust burst out, splashing and scattering around the deep valley.

"boom!"

The Black Demon King beat the colorful light shield barrier again, and the sword of the Thousand-mouthed Soldiers was shaking continuously, and the light shook.

Many swords deviated from their original position, and they collided with each other and made a jingle sound.

Many Wuzong sects gritted their teeth and flew their fingers, killing their life-long energy into the Thousand Sword Formation.

But at this moment, the black iron chain on the right leg of the Black Evil Demon King suddenly broke open.

Suddenly, the Black Demon King roared excitedly, raised his extremely thick right leg and thrust hard towards the colorful light wall.

"Boom!"

With the loud noise, the colorful light wall was bombarded by terrifying forces, and a gap suddenly burst out, and the colorful light passed away wildly.

On the ground, the eighteen strong men of Wuzong all changed their faces, pale and bloodless, and made muffled groans one after another.

Several Wu Zongs were shocked by the power of the Thousand Sword Formation, and blood was spewed out when they opened their mouths, and they were actually injured.

When He Wuhen saw the scene underground, he noticed that the iron chain on the black evil demon king's legs were broken, and he was immediately worried.

The huge iron chain has been intact, so how could it suddenly break?

Thinking of this problem, he suspected that someone might have secretly destroyed it.

He immediately extended the reconnaissance map to the limit and investigated the situation underground.

However, after a careful search and ten breaths, he did not see any clues.

Unwilling to give up, He Wuhen asked the investigation map to extend to the near the broken iron chain and observed it carefully.

Finally, he saw a dark fog located near the colorful light wall, surging and rolling, bombarding the colorful light wall.

This dark mist actually cooperated with the Black Demon King inside and outside, blasting a large hole into the colorful light wall.

Soon, the dark mist poured into the interior of the colorful light shield and rushed towards the last iron chain.

He Wuhen shouted coldly, bursting the Yuanli to its limit, and finally making the reconnaissance map clearer.

After a closer look, he realized that the dark mist actually contained a figure.

Judging from the appearance, he was a tall middle-aged man, covered in dark mist, almost blending with the mist.

The middle-aged man turned into gray mist and poured into the huge iron chains. He quickly wrapped the iron chains and kept rolling.

Then, the huge iron chain as thick as a water tank was actually thinning at a speed visible to the naked eye, and a gap gradually appeared.

Seeing this scene, He Wuhen finally understood that it was the gray fog that had been secretly destroying the Thousand Sword Formation and helping the Black Evil Demon King escape the seal of the formation.

Thinking of this, a murderous aura surged in his heart.

At the same time, almost half of the eighteen Wuzong people in the deep valley were injured.

The remaining uninjured people were also superimposing the power of the formation with all their strength to suppress the bombardment of the Black Evil Demon King.

Their faces were distorted, beads of sweat the size of beans appeared on their faces, and the veins on their foreheads were thundering, obviously it could not last long.

"No! You must kill the person who destroys the formation, otherwise the Black Evil Demon King will inevitably break free from the seal!"

While he was anxious, He Wuhen felt a little helpless.

Although he could see the gray mist destroying the formation, he could not stop it.

He is the Wuzong of the Fire-type Yuanli. He cannot use the Earth-type Yuanli like Luo Changting, and sneak into the underground a hundred feet deep.

However, his eyes quickly swept around the Thousand Sword Formation and found that there was a powerful Wuzong not far away, who was practicing the earth-type Yuanli.

The strong man of Wuzong was Elder Li from Qianjiangmen, who had the strength of a third-level Wuzong.

In desperation, He Wuhen didn't care too much and shouted to Elder Li: "Elder Li! Someone destroyed the formation a hundred feet deep underground. Come and help me stop him!"

Elder Li was using his devil-suppressing fingering technique with all his strength, and superimposing the power of the formation, and when he heard He Wuhen's shouting, he became more and more angry.

"Nothing! Why don't you suppress the Black Demon King quickly? Why are you talking nonsense?"

Obviously, Elder Li did not believe He Wuhen's words. With his mere first-level Wuzong's strength, how could he see the scene a hundred feet deep underground?

Several other Wuzong strong men also heard He Wuhen's words and all looked angry and threw stern eyes at He Wuhen.

He Wuhen was worried, but he was very helpless.

Fortunately, eight more powerful Wuzong people rushed over at lightning and jumped into the deep valley.

The head of these eight people is Chu Tianxiong, the head of Taixuan Pavilion, and the rest are the elders of Taixuan Pavilion.

He Wuhen quickly shouted loudly, telling Chu Tianxiong that someone was destroying the formation underground.

Chu Tianxiong had known that someone had destroyed the formation, but he could not find out the reason.

Now that he suddenly got the clue, he let three elders who practiced the earth-type Yuanli dive deep into the ground.

Soon, the three elders sneaked into the depths of seventy feet underground, and used their spiritual sense to detect the black fog, and all rushed towards the middle-aged man.

Suddenly, the middle-aged man noticed the danger, turned into a cloud of gray fog, and quickly fled to the distance.

The black fog escaped very quickly. It was like a swimming fish in the ground, and it quickly threw away the three elders.

He Wuhen had to chase after him, and always used the reconnaissance map to lock the black fog, and informed the other three elders of the direction of his escape.

Half a quarter of an hour later, He Wuhen had chased him dozens of miles away from the Thousand Sword Formation.

The three elders of Taixuan Pavilion were sneaking underground too slowly and could not keep up.

The black fog saw that it had shaken off the three elders and thought it had escaped safely.

He immediately rose to the ground, quickly got out of the ground, sitting on the ground, gasping for breath.

At this moment, He Wuhen, wearing dragon flame armor and holding a blood-drinking knife, fell from the sky.;
