I saw that the cluster of chaotic fire on Du Changsheng's head suddenly moved, and a slender line of fire was separated like a silkworm peeling silk, and it formed a circle of fire, and under Du Changsheng's urging, it instantly came to the black mist to surround it.

"Ahh

The devil's screams sounded instantly, and the black mist, which had always been overwhelming, was directly burned into nothingness the moment it touched the circle of fire, and it was impossible to get out at all.

I didn't expect that even the power of the divine soul could be incinerated!

Du Changsheng's heart was excited, and he hurriedly urged the fire circle to shrink.

The moment the dantian was occupied, he thought that the chaotic fire in the heavenly vein might be able to deal with the power of the demon's divine soul, so he kept showing weakness and luring the enemy deeply, just to introduce him into the heavenly vein, close the door and beat the dog.

It seems that the Chaos Fire did not disappoint him!

"Poof!"

The black mist continued to decrease sharply as the circle of fire shrank, making the sound of things burning, and the demon inside screamed even more.

"Ahh No, little friend, you have something to say! Stop! ”

In less than a moment's time, the black mist had been cut in half, revealing the power of the demon's origin soul inside, and as long as it lasted for a while, it could truly be incinerated completely.

Listening to the constant begging for mercy from the demon inside, Du Changsheng did not have the slightest mercy in his eyes, but instead urged the fire of chaos with all his might, wanting to kill him, for fear that something would happen again.

Because of an old devil like this who has lived for 10,000 years, no one knows what other means he will have.

As time passed, the color of the chaotic fire above his head became fainter and fainter, as if a small flame swaying in the wind would be extinguished at any moment.

Du Changsheng's face was also pale, after today's changes, whether it was physical strength, spiritual power or divine soul power, there was a huge consumption, if he didn't grit his teeth and insist, I am afraid that he would pass out in the next second.

The vigorous black mist besieging the circle of fire in front of him had been burned away, leaving only a fist-sized mass of Origin Divine Soul power struggling.

As if he really felt the fear of dying, the only remaining mass of the demon's divine soul origin trembled violently, and the terrifying divine soul power exploded, wanting to make a final struggle and escape from the fire circle.

"Give me death!"

Du Changsheng's body trembled, and he almost panicked, but he immediately gritted his teeth, regardless of the faint state of the chaotic fire, he urged the fire circle to shrink with all his might, wanting to refine the last divine soul origin of the demon.

"No!"

"You can't do that! By doing so, you will ruin yourself! ”

"Kill me, and your Flame of Chaos will be extinguished! From now on, the Chaos Primal Qi will no longer be born, and all the proud talents you have will disappear! ”

The terrifying voice of the demon came from the source of the soul that was constantly struggling.

Hearing this, the movement in Du Changsheng's hand paused.

He slowly lowered his head, looking at the expression on the face of the demon trapped in the ring of fire, and a hint of hesitation flashed.

The Chaos Flame above his head is now close to extinguishing, and the original dark yellow has faded to nearly transparent, if he urges it to get the power to completely destroy the demon, the Chaos Flame will definitely be extinguished.

At that time, all the opportunities that he has now will disappear, after all, his spiritual power, physical body, and even divine soul that are beyond ordinary people are all brought about by the chaotic fire formed by this chaotic initial qi.

For the sake of a demon who buried his future, this deal is really not worth it.

But this kind of old devil who has lived for 10,000 years is too dangerous to stay in the heavenly veins, no one knows what will happen later, if he is not careful, he will be calculated by it and become a puppet of others, so he can only be killed quickly and eliminated forever.

For a while, Du Changsheng was in a dilemma.

"Wait! We can discuss, if you don't worry, I can make a soul oath! ”

Seeing that Du Changsheng hesitated, the demon hurriedly screamed and shouted, for fear that Du Changsheng would refine him with a ruthless heart.

"Soul Oath?"

Du Changsheng's eyes condensed slightly, the movements in his hands slowed down, staring coldly at the wisp of divine soul origin in front of him, and said in a deep voice:

"How do I know if this is your trick?"

As the son of the Taixu Divine Sect, Du Changsheng naturally knows what the soul oath is, that is, to initiate an oath with the origin of the divine soul, if the oath is violated, no matter how strong the soul oath is, the soul will be scattered and will not enter reincarnation.

Moreover, the secret technique of casting the soul oath had long been lost, so Du Changsheng didn't dare to believe the devil's words easily.

After that, Du Changsheng gritted his teeth and urged the fire ring again, not daring to give the demon a chance to breathe.

"Don't! What I'm saying is true! The Adversary hurriedly begged for mercy.

"Anyway, there is a chaotic fire controlling me, and I can't escape, I can swear now, and then my life and death will be between your thoughts!"

As he spoke, the demon no longer talked nonsense, and only a wisp of divine soul origin suddenly flashed a ghostly light, and an obscure voice sounded, and a mysterious language that did not belong to the human race at all came out of it.

Because it was surrounded by chaotic fire, Du Changsheng was not afraid of what tricks he played, he just watched coldly from the side, as long as the demon dared to play any tricks, he would wipe it out at all costs.

The obscure spell lasted for a quarter of an hour before slowly dissipating, and at the moment it ended, Du Changsheng suddenly felt a vibration in the depths of his soul, and then the power of the divine soul in front of him seemed to have a new connection with himself, as if there was an invisible thread connecting the two together.

In the next second, Du Changsheng's mind moved, and he found that he could clearly feel the demon's soul fluctuations at this moment, as long as he wanted to, he could even wipe it out with a thought.

"This is the Soul Oath?"

Du Changsheng was surprised.

"That's right! Well, I didn't lie to you, did I? Now that we have successfully formed a master-servant relationship, my life is in your thoughts, and if you die, I will be gone! ”

The demon in the fire circle shouted hoarsely, his voice weak with a hint of unwillingness.

Who would have thought that the terrifying demon would sign a soul oath with a hairy boy and become someone else's prisoner.

But in order to survive, he can't care so much, after all, after enduring 10,000 years of loneliness, he can finally break free from here, and he will not give up this opportunity.

"Quick... Fast! Remove this ring of fire, I'm going to be burned to death!" ”

The screams of the Adversary were heard again from the black group.

Seeing that the demon no longer threatened him, Du Changsheng immediately waved his hand to remove the fire ring, because if it continued, the chaotic fire above his head would probably really be extinguished.

Seeing that this crisis was finally resolved, Du Changsheng's tense nerves relaxed slightly, and before he could take a breath, a strong feeling of weakness came like a surging tide.

Only when he relaxed, the state of his body and soul that was close to running out of oil directly made his eyes darken, and he fell into a deep coma......
