Since he has cultivated the power of the eye, the first change can increase the strength by nearly one percent.

Then, if the other seven dragon powers are cultivated together, most of them can increase their strength by one-tenth.

The higher the realm, the more difficult it is to improve the strength, not to mention, one percent, even one thousandth or one thousandth is quite difficult.

So, Cheng Bo hurriedly released the power of the seal's other energy mocking wind, and then ran the exercises to refine.

With the completion of the first transformation of the power of the mocking wind, Cheng Bo found that his body, strength and even soul have been strengthened again, and this time the degree of strengthening is even greater, increasing by one percent on the current basis.

Suddenly, Cheng Bo came to his senses, he had gone in the wrong direction of cultivation, he shouldn't have cultivated the power of the imprisoned ox alone, the nine sons of the true dragon were all the sons of the true dragon, each of them had inherited a certain talent of the true dragon, and the unity of the nine dragons was the true dragon.

Therefore, the correct cultivation method of "True Dragon Nine Changes" should be to cultivate the power of the nine sons together, so that they can promote and benefit each other.

Thinking of this, Cheng Bo couldn't help but feel a little excited in his heart, if he cultivated the power of the remaining six dragons, then his strength would definitely not increase by only one-tenth, it might be more.

Sure enough, as Cheng Bo expected, after he cultivated the power of Pu Prison and completed his first transformation, his strength increased by at least three percent on the existing basis.

The ascension is gradually increasing.

"Good!"

This discovery made Cheng Bo overjoyed.

It only took nine days for the power of the fox to complete the first transformation.

It took eight days to complete the first transformation with the power of the tyrant.

It took seven days for the power of the fierce to complete its first transformation.

It took five days to complete the first metamorphosis.

It only took three days for the power of the mantis to complete its first transformation.

Just after Cheng Bo cultivated the power of the Nine Sons of the True Dragon, a earth-shaking change suddenly appeared in his body, and the nine forces had an additional connection with each other, forming a cycle, and at the same time, a drop of the power of the True Dragon was also born.

When Cheng Bo used this true dragon power to refine his body, his physical strength directly increased by three times.

Coupled with the increase in the power of cultivating eight dragons, Cheng Bo's own strength has at least doubled.

This is only the first transformation that has improved so much, what if the cultivation is the second or third transformation?

As a result, Cheng Bo began to bombard the seal continuously, collecting the power of the True Dragon Nine Sons contained in the seal.

When he had collected enough power, the system prompt sounded, and the upgrade had been completed, and the system had been promoted to the twenty-first level.

Suddenly, Cheng Bo's heart moved, the relatives who stayed in the intermediate plane could say that they were living day by day, he had been practicing for three months, and they had spent ninety years there.

So, he simply crossed over to that intermediate plane.

In this intermediate plane, he spent five years to reach the level of the second transformation of the other eight dragon powers, and his strength made a breakthrough again, increasing more than ten times on the original basis.

He was sure that even if he didn't become a prisoner cow, he could sweep through the upper gods with his body alone.

However, he had to face the main god, so this strength was far from enough, so he came to the Tianfeng World again to collect the power of the nine sons in the seal.

In this continuous cycle, a year has passed in the Overworld.

And Cheng Bo cultivated the other eight dragon powers in addition to the power of the imprisoned ox to the fifth change.

Compared with a year ago, his strength has increased by at least hundreds of times.

Although he didn't know if he could fight against the main god, he knew that if he faced the lord of the Black Plus Country again, Cheng Bo would definitely be able to kill him with one finger.

Moreover, he can perform a real dragon transformation.

Qi Qi urged the nine transformations and he could directly transform into a true dragon, but the time was very short, and it could only last for about ten minutes.

After turning into a true dragon, that explosive power made Cheng Bo feel that even if a main god stood in front of him, he could smash it with one punch.

Another thing worth mentioning is that during the year, the system has been upgraded by one level, to twenty-two, and, by now, the progress bar has reached seventy-seven percent, which is not far from another upgrade.

It's just that what makes him strange is that the system doesn't release any tasks.

After communicating with Tang Xinyu, he knew the reason, he now has intermediate permissions, so the system will release tasks closer to his actual situation, this year, he has been in retreat and penance, and the system will naturally not issue tasks to disrupt his practice.

However, after hiding for a year, Cheng Bo also decided to return to the main world.

But for the sake of safety, he decided to leave his family in the intermediate plane.

However, considering the time flow rate of the intermediate plane, he simply captured the Heavenly Dao of this world, and then adjusted the time flow rate to a one-to-one level through the system.

"Whoosh!"

The figure flickered, and Cheng Bo appeared on a certain planet in the Overworld universe.

I don't know how much has happened in the Overworld in the year he's gone.

Log in to the interstellar network and browse hot news.

However, as soon as he logged in to the interstellar network, Cheng Bo sensed that someone was locking his location through the interstellar network.

He didn't care about this, but continued to browse the news leisurely.

The most sensational event of the year was his assassination of Luke Cumberland, and at the same time, his true identity "Cheng Bo" was also revealed.

Suddenly, Cheng Bo's heart tightened.

Because he found a piece of news that someone had discovered the existence of the water blue star, and a team of superior gods rushed over.

He glanced at the time of the news release, exactly a day ago.

At the speed of the above gods, it would take half an hour at most to catch up with the water blue star.

"I hope Aqua Blue Star is okay!"

Cheng Bo decided to return to Shui Lanxing immediately, after all, it was the place where he was born and raised, and he had a special feeling.

Just as he was about to leave, five figures appeared above the planet.

As soon as these five people appeared, they sacrificed a powerful artifact and sealed off the entire planet.

"Haha, that kid didn't escape!"

One of them couldn't help but laugh when he saw that Cheng Bo was also sealed on the planet, and he couldn't help but get excited at the thought that he could obtain two main artifacts and ten drops of the power of the main god just by killing him.

"Without further ado, kill him quickly, lest the others get the news!" the other god urged.

"Yes, let's work together to kill him and claim the reward!"

The remaining three high-ranking gods all nodded in agreement.

"Whoosh whoosh!"

Five figures flashed and appeared directly above Cheng Bo.

Cheng Bo glanced at these five people, judging from the aura on their bodies, they were not weaker than the Black Plus Lord who was killed by him, and there was even one stronger than the Black Plus Lord.

"Give you a chance to get out, otherwise, there will be no mercy!"

Concerned about Shui Lanxing, Cheng Bo was in a very bad mood, and his tone was also full of impatience.

Hearing this, the faces of the five superior gods all became quite unkind.

"Don't talk nonsense with this megalomaniacal, kill him!"

In the next moment, the five high-ranking gods all cast their divine skills and slaughtered towards Cheng Bo together.

"Look for death!"

Cheng Bo's body flickered, and he avoided the attack of the five people, and the planet on his body was directly shattered, and then, Cheng Bo kept pointing out, and his energy was many times faster than lightning, and one of the high-ranking gods was bombarded on his body before he could see it clearly.

Suddenly, clusters of dazzling brilliance exploded on his body, but they shattered one after another, and when the body protection artifact divine light exploded, his body also exploded, turning into a cloud of blood mist, but these blood mist were filled with a dead air, and there was no possibility of recondensing his body at all, that is to say, Cheng Bo killed a superior god with one finger.

"This?"

Seeing this scene, the eyes of the other four superior gods were all straight, how could this be possible?

Immediately, an unspeakable horror arose in their hearts.

"Run!"

I don't know who shouted, and the four of them rose into the sky one after another.

"I said you would die if you didn't leave!"

Cheng Bo flicked his fingers again, and the body of another high-ranking god exploded, turning into a lifeless blood mist.

Then, he flew up in the air, came to the top of the head of a superior god, slapped them to death, and then threw two punches at the other two, who snorted and their bodies exploded......

After killing these five superior gods, Cheng Bo's figure disappeared in a flash, and he headed towards the water blue star at the fastest speed.
