It was as if the whole world was shaking, and the purple flames were becoming more and more violent, like endless waves, terrifying, breaking through the entire heaven and earth, the earth, mountains and rocks, etc., as long as they were visible, all of them were burning.

Cracks appeared in the parched earth, like spider webs, and the flames became more violent.

The violent breath swept the entire heaven and earth, the flame was ten thousand feet high, permeating the entire heaven and earth, terrifying and abnormal, Chu Xun and the two were like a flat boat in the endless ocean, but the black light, it seemed that the most solid existence in the world, could not be destroyed.

The Holy Maiden of Yaochi looked at Chu Xun and wanted to say something, but under the influence of that violent aura, her eyebrows frowned slightly and looked ahead.

Where, there seemed to be some great terror brewing, and everything seemed to be affected by the deepest part of the Fire Domain.

At this time, in Chu Xun's induction, a familiar aura appeared, which was the same as the breath of the mysterious black iron.

It is in the middle of this fire domain.

"Wait for me here."

Chu Xun looked at the Holy Maiden of Yaochi and said directly, and then in his hand, a drop of essence blood appeared.

Suddenly, in it, an even more huge aura emerged, like a burning blood flower, containing this extremely surging power, which was even stronger than the temperature of the surrounding flames, making the Holy Maiden of Yaochi frightened for a while.

"This is my heart's work, I am born close to fire, and it is impossible for these flames around me to hurt you."

Subsequently, this drop of essence blood appeared around the Holy Maiden of Yaochi, isolating all the surrounding flames, and after Chu Xun said this, he left this place directly and headed towards the center of the fire domain.

The Holy Maiden of Yaochi looked at Chu Xun's back, stretched her brows at the moment, and did not choose to follow.

Chu Xun didn't want the Holy Maiden of Yaochi to follow, the mysterious black iron was one of his biggest secrets, although she knew some, but it was not specific, this matter had to be hidden from everyone except him.

He directly passed through the seventh and eighth layers of flames, and the terrifying flames around him turned into real dragons and constantly hovered above the void, as if he was about to recover successfully and turn into a real flame dragon, and the temperature here was already unimaginable.

Streams of black light continued to swim on his body, isolating all the surrounding flames, and above his head, the Sky Swallowing Demon Jar was constantly rising and falling, emitting endless black light, as if it could suppress everything.

Although Chu Xun is not aware of the flames here, but he needs the support of strong divine power, and now the eighth layer is completely unable to use divine power, and will be directly incinerated, of course, if he cultivates strongly, he can ignore these, but the current Chu Xun has not yet reached it.

"I'm afraid it's the flame of the ninth layer, and even the saints can be burned out."

Chu Xun frowned, if it weren't for the Heaven Devouring Demon Jar, he would not be able to move an inch in that ninth layer, it was a flame that could threaten the saint, although Chu Xun was a golden crow, but his cultivation had not yet reached that level.

He passed through the mist-like flames of the eighth layer, and finally saw the ninth.

It's very quiet, not even a sound, it's like coming to a chaotic land, except for the earth, there is no existence, the white expanse, the ninth layer, is completely similar to the outside world.

But Chu Xun can be sure that once he enters this ninth layer, he will be something else.

The more tranquil it is, the more dangerous it is.

A glimmer of light flashed in Chu Xun's eyes, he walked towards the ninth layer, the Heaven Devouring Demon Jar above his head was constantly swallowing black light, isolating everything around him, he was reviving the Extreme Dao Emperor Soldier, not to strike a blow, but just to protect himself.

Even if it was the ninth layer of the Fire Domain, the flames that could threaten the saint were there, but in front of the Extreme Dao Emperor soldiers, it was nothing at all.

The ancient emperor, the combat power is unparalleled, there may not be a statue in an era, looking down on the universe, the imperial soldier is the emperor's instrument of enlightenment, and can completely ignore these.

He slowly walked forward, the black light emitted by the Heaven Swallowing Demon Jar around him trembled for a while, but it soon stabilized, and Chu Xun continued to pour his divine power into the Heaven Swallowing Demon Jar, so that the surrounding flames could not hurt him in the slightest.

It seems that there is no flame, but it exists all the time, and in this chaotic place, it is dangerous for the saint to come.

Chu Xun kept moving forward, he didn't use his Yuan Shen power, and his hands kept sliding inexplicably, and a ray of light continued to burst out in his hands, turning into the earth and disappearing.

This is the Source Heaven Technique, Chu Xun can't sense the surrounding aura now, but if he uses the Source Heaven Technique to communicate this area, he can understand everything in an instant, and the mysterious black iron aura that suddenly appeared just now may be in this ninth layer.

Heaven and earth were chaotic, Chu Xun kept searching, and the light emitted by the fingers hit the earth, rising endless brilliance, and then there was annihilation, for two hours in a row, he was not in a hurry, but cautious, almost every inch was not spared.

But the breath he sensed before disappeared like a fish entering the sea.

Chu Xun confirmed that his induction was not wrong, so he still did not give up, and kept looking for it.

"Buzz!"

At this moment, after Chu Xun searched continuously for more than ten days, a trace of roaring suddenly appeared in his mind.

"To the east!"

Suddenly, Chu Xun's eyes flashed, and then he moved sideways for hundreds of meters, appearing beside him.

Relying on the mysterious black iron, standing quietly above the void, without any breath, endless terrifying flames burning, but it has no effect on this piece of black iron, it is like an eternal existence, unshakable in the slightest.

Moreover, this piece of black iron was larger than any black iron that Chu Xun had ever seen before.

The black iron that Chu Xun had before was all three or four inches in size, and the one in front of him was at least ten inches in size, which was even bigger than the two pieces that Chu Xun had obtained before in his body combined.

And what made Chu Xun feel even more unusual was that on this piece of mysterious black iron, lines flowed, and these lines constituted an indescribable rhyme, as if heaven and earth were condensed, not like they were refined by people, incomparably perfect, these lines were very profound, and they fit perfectly with the black iron.

"It's... What is it? ”

Chu Xun frowned, he could clearly feel the mystery of this piece of black iron.

He seemed to have seen it somewhere, as if it was hidden in the deepest part of his memory, but he really couldn't remember it, especially these lines, which seemed to give him an inexplicable feeling.

After thinking about it for a long time, Chu Xun didn't think of any clues.

Taking a deep breath, Chu Xun was not thinking about this, as he collected more and more fragments of black iron, he would slowly reveal the secret of this mysterious black iron.

Recently, my thinking is not good, so I adjusted the state and straightened out the outline.
