Looking at the dense demon soldiers in the sky, covering the sky and the sun, and the number of tens of billions, even a single Tianzun secretly felt frightened.

However, the Demon Emperor seemed quite calm, and then said to the sky: "Heavenly Dao, it's your turn to make a move!"

Suddenly, the brilliance of the laws between heaven and earth surged, and the power of the laws that had just weakened returned to its original level in an instant, and the demon soldiers who were originally suspended in the sky fell down like dumplings.

Falling from the void hundreds of thousands of meters high, even though these demon soldiers were extremely powerful, they still fell to pieces, blood plasma.

In an instant, most of the tens of billions of demon soldiers fell to death.

The rest were barely dragged by the demon soldiers, demon marshals, and demon kings, suspended in mid-air.

"What's going on?"

The female demon queen of the ruin snake clan shouted in horror, and the other demon emperors also changed color.

"The Heavenly Dao of this world has not been injured, we have been fooled!" a rather clever Demon Emperor shouted, "Quick, leave this world!"

Then, these more than 100 Demon Emperors rose to the sky one after another and flew out of the sky.

"Where to go!"

Suddenly, a figure flashed, and dozens of figures were added above.

It was the thirteen Heavenly Venerables of this world, as well as Cheng Bo and others, including the Demon Emperor.

"Demon Emperor, you actually betrayed us?"

These Demon Emperors saw the Demon Emperor standing with the powerhouses of this world, and these Demon Emperors still didn't understand what was going on, it was the Demon Emperor who betrayed them and introduced them into this world.

"This emperor is the emperor of the demon race, I represent the demon race, how can I betray it!" said the demon emperor with a smile.

"Shame on the traitor, the ancestral demon will definitely not spare you!"

A Demon Emperor roared.

"Ancestral Demon?"

The Demon Emperor smiled: "Bendi won't give them a chance to recover at all!"

As soon as the words fell, the Demon Emperor had a blood-red long sword in his hand.

"Kill!"

The blood light flashed, and the blood-red sword qi turned into a swift streamer, and in an instant, the heads of the seven demon emperors were cut off, and they were extremely ferocious.

"Damn it, kill this traitor!"

The Demon Empress of the Ruin Snake Clan shouted angrily, and quickly sacrificed the Demon Artifact to kill the Demon Emperor.

The other Demon Emperors also knew that the threat of the Demon Emperor was far superior to that of the local powerhouses, so they also took action.

However, the strength of this group of Demon Emperors was deliberately suppressed by the Heavenly Dao, and it could only be compared with the early stage of Jindan, and although the Demon Emperor was also suppressed, because of the special care of the Heavenly Dao, he could at least exert the strength of the late Yuan Infant stage.

"Puff puff!"

The blood-red sword light continued to shine, and in an instant, the remaining Demon Emperor was actually slaughtered by the Demon Emperor with a blood sword.

Seeing this scene, the local powerhouses were secretly frightened.

Cheng Bo, on the other hand, had a light in his eyes, and his devouring divine power was urged to the limit, frantically absorbing the demonic essence from the void and transforming it into life essence.

Because these demonic essence qi were too abundant, as he absorbed it, a large amount of demonic essence qi poured into his body, and it was transformed into a massive amount of life essence in an instant.

"Click!"

Like the sound of shackles shattering, Cheng Bo was overjoyed, but it was his devouring divine power that advanced again at this moment and reached the level of consummation.

"Okay, the Devouring Divine Power is too timely!"

Cheng Bo was overjoyed, and the speed at which the demonic Dao essence surged towards him increased greatly.

The Demon Emperor glanced at Cheng Bo with deep understanding, and then rose to the sky and flew out of the sky.

"Kill!"

The local powerhouses began to rush towards the remaining demon soldiers, and the Seven Super Divine Monarchs and Han Mengxue also followed and killed them, but it was the ten children of fate who followed the figure of the Demon Emperor.

The demon soldiers who have lost the Demon Emperor have become lambs to be slaughtered, not to mention resisting, even if they are suspended in mid-air, it is very difficult.

Therefore, in less than a quarter of an hour, all the remaining extraterrestrial demons were wiped out.

And after Cheng Bo urged the "True Dragon Nine Changes" to continuously refine the massive amount of life essence transformed by the demonic essence qi, he finally pushed the power of the imprisoned ox to the level of the seventh transformation, and directly entered the transformation.

But there is still plenty of demonic essence in the void, and Cheng Bo is not willing to waste it at all and continues to devour it.

Soon, the strength of the other four dragons also reached the level of the sixth transformation.

"Oh no!"

Suddenly, Cheng Bo sensed that the demonic spirit of the heavens and the earth had actually been summoned, and they all gathered into a river and rushed towards the sky.

He thought of the departed Demon Emperor, and guessed that these Demon Dao Essence should have been summoned by the Demon Domain, and the one who controlled the Demon Domain must be the Demon Emperor.

"If you want to take food, it depends on whether I agree or not!"

Cheng Bo sneered, intensified his devouring efforts, and directly intercepted these demonic dao essences and pulled them into his body.

In the Demon Domain, the Demon Emperor had already dived into the depths of the Demon Domain, sitting here, surrounded by a rich and extreme demonic qi, and between the swallows, these pure demonic Dao essences were constantly converging into his body.

made his aura continue to rise and skyrocket......

"Humph!"

Suddenly, the Demon Emperor sensed Cheng Bo's behavior, and couldn't help but let out a cold snort, pinching a trick, and suddenly, the entire Demon Domain turned into a huge whirlpool, and then, in the world below, the dimensional space opened, and in an instant, the remaining demonic qi was pulled in.

"Damn it!"

Looking at the dissipated demonic spirit around him, Cheng Bo couldn't help but be quite annoyed.

However, this time his harvest is still huge, as long as he waits for the power of his nine sons to complete the sixth transformation, and the power of the prison ox to reach the seventh transformation, his strength will definitely be able to skyrocket dozens of times.

However, now that he is in the midst of transformation, it is not appropriate for him to go to the Demon Emperor to settle accounts, and he has to wait for the transformation to be completed.

The demons outside the sky have been destroyed, and the world is well.

And after the Demon Emperor was gone, he disappeared, but Cheng Bo knew that he would definitely appear.

One day.

Two days.

Three days.

Five days.

Cheng Bo's power of the imprisoned ox completed the transformation first, reaching the seventh transformation, and the power of the imprisoned ox after the transformation was constantly running in the body, washing and refining his body and soul, making his body and soul improve all the time.

This went on for several days before it was completed.

"My current strength, even if I don't change my body, I can resist the main god, if I transform into a prisoner cow again, I will definitely surpass the main god, and if I transform into a real dragon again, I will definitely be able to kill the main god in seconds!"

In the following month, the other Nine Sons completed the sixth transformation, and at the same time, they also strengthened Cheng Bo's body and soul several times.

Then, Cheng Bo went straight to the sky.

After all, the Demon Emperor is a trouble, so Cheng Bo plans to get rid of him.

Powerful divine thoughts rushed out, instantly covering a radius of nearly 100 million miles outside the sky.

Then he stepped out and came to a void, and saw a wisp of clone left by the Demon Emperor there.

The Demon Emperor clone smiled at the corner of his mouth and said: "I thought you would come after a while, but I didn't expect you to come so quickly, this cooperation is very pleasant, I believe we will meet soon!"

As soon as the words fell, the doppelganger of the Demon Emperor directly dissipated and disappeared into the void of the universe.

Cheng Bo frowned, stood in place and stared for a long time before leaving, he faintly felt that he had still fallen into the calculation of the Demon Emperor, but he didn't know what the other party was seeking.

Fortunately, this primordial world has been preserved after all, and his strength has also been greatly improved, so there is no need to stay in this world anymore.

A few days later.

In the reluctance of Chen Yu, Han Mengxue, Xu Ya and others, Cheng Bo took the Seven Great Divine Monarchs to break through the boundary.

Returning again, Cheng Bo appeared on the water blue star.

However, there are no humans on the current Aqua Blue Star.

After checking the state of the Lower Ancestral Demons first, Cheng Bo led the Seven Great Divine Monarchs to cross over to a high-level plane again.

As soon as he stepped into this high-level plane, Cheng Bo found that the creatures of this world were fighting against the demons outside the sky, but the creatures of this world obviously had the upper hand and were chasing and killing the demons outside the world.

Suddenly, Cheng Bo sensed a familiar aura.

Dodge into the sky and find the corpses of several Demon Emperors, and the Demon Domain is nowhere to be found.

"Demon Domain!"

Cheng Bo's mind exploded instantly, and he immediately understood what the Demon Emperor was seeking, and he seemed to be collecting the Demon Domain.

"Could it be that these Demon Domains are very important to him?"

Cheng Bo said secretly.

Subsequently, he and the Super God Monarch left again and continued to cross.

After crossing several times in a row, he found that he was one step too late, and the demon domain where the demons outside the sky were located had been taken away by the Demon Emperor.

Just when he wanted to continue to travel to the high-level plane with the invasion of the Extraterrestrial Demons, Tang Xinyu told him that the remaining high-level planes did not have the Extraterrestrial Demons Invasion.
