The bottom of the sea calmed down, and the Great Demon King thought about it carefully, feeling that this universe was quite dangerous, and the most worrying thing was not the Celestial God Clan, the Five Immortal God Dynasties, etc., but the killing tools put in by a group of 'people' in such a cosmic sea.

However, the Great Demon King didn't dwell on this matter for long, and then he began to look for something in this true dragon's lair**.

It is not like a palace, but like a small world, the space is quite vast, in addition to some magnificent palaces, there are mountains and rocks and rivers in the distance.

Some of the mountains are as high as 10,000 feet, standing at the end of heaven and earth, and the palace is full of vastness and ancient atmosphere.

This is a palace that may be older than the ancient times, and it is the palace of the supreme powerhouse of the True Dragon Clan, the top clan of other universes.

Sou!

The Great Demon King was extremely fast, like a flash of lightning, quickly sweeping across the land.

"Huh?"

Suddenly, the Great Demon King felt a strange aura that actually resonated with his body.

"The Hall of Secret Laws. ”

Then, the Great Demon King felt something, and looked towards that place, a palace stood dozens of miles away, and there were three such ancient characters on it, although I didn't know it, but the meaning was very clear.

The Great Demon King quickly rushed towards this secret magic hall, and when he arrived here, the feeling of resonance became stronger and stronger.

The Great Demon King did not hesitate and stepped into the palace.

Rumble!!!

At this moment, as if the world had been opened, the palace was trembling violently, and then, the Great Demon King's heart shook.

"True Dragon Alchemy, a further exercise of the Purple Gold Alchemy!"

For two minutes, the Great Demon King was in shock.

This secret hall contains the 'True Dragon Body Refining Secret Technique' of the True Dragon Clan, and it has the same root and origin as the Purple Gold Body Alchemy Technique he obtained before, and the True Dragon Body Refining Secret Technique is the full range of Purple Gold Body Alchemy Secret Techniques.

"Perhaps, this is what the old turtle senior said I need. ”

The Great Demon King has a slight understanding.

True Dragon Alchemy Secret Technique, this is the secret technique of the Zhen Clan of the True Dragon Clan in the outer universe, and the way triggered by this secret technique is not as secret as ordinary secret techniques and secret methods, but it requires cultivating the Purple Gold Alchemy Technique to a fairly high level to resonate.

Earlier, Lei Ming, Liu Mu and the others had indeed practiced and comprehended the Purple Gold Alchemy Technique, but their realm of cultivating this secret technique was far from meeting the requirements of the True Dragon Secret Technique.

Bang!!

Purple qi was permeated, frantically shaking, at this moment, the entire true dragon lair was trembling, and a terrifying aura was overwhelmingly converging here.

"I didn't expect that there would be someone in this universe who could trigger the True Dragon Body Refining Secret Technique I left behind, I really wish I could take a look at you, but unfortunately, I don't have time. ”

Then, a dragon shadow that stretched for an unknown number of miles condensed in the void, making such a rumbling sound.

"Lucky junior, I hope you can make good use of this secret after you get it, and finally get out of this cage. ”

The phantom of the true dragon was opening, and its voice was blank, as if it could shake the stars.

At this moment, even the Great Demon King felt that his mind was about to collapse.

Undoubtedly, this true dragon is definitely in the Supreme Realm, and it is not an ordinary Supreme Strongman.

In the end, this true dragon phantom collapsed, and the Great Demon King sighed in his heart.

In fact, he had long known that the True Dragon Supreme had already died, and what was left behind was just a mark of inheriting the True Dragon Alchemy Technique.

In the following time, the Great Demon King did not leave, but stayed here to comprehend the secret technique of true dragon body refining.

For a month, the Great Demon King remained motionless, as if petrified, but his body was flowing with purple light.

The True Dragon Body Refining Secret Technique is powerful and complex, and even the Great Demon King has spent more than ten days to comprehend it thoroughly.

Moreover, this is still the reason why the cosmic cultivation system can be assisted at any time to reach the current realm, otherwise, if you want to comprehend the true dragon secret technique, you don't know how long it will take.

And in the second half of the month, the Great Demon King began to temper his body with this kind of body refining secret technique.

At this moment, he knew that he really had to go to the extreme realm of this realm.

The strength of the physical body continues to surge, this is one of the strongest body refining secret techniques in the outer universe, and it can even be said that it can be regarded as the top body refining secret technique in thousands of universes, several levels higher than the Heavenly God Alchemy and Flying Immortal Alchemy.

Time passes here, and in the blink of an eye, three months have passed.

In the past three months, the Great Demon King has not wavered, but the aura revealed by his body has been growing.

And in these three months, the elders of the martial palace are going crazy.

"Where the hell did the Great Demon King go?"

An old man said anxiously.

"Isn't it going to be another hundred years of retreat?"

There are still people who doubt it.

Lord Ye, Lord Song, Lord Qin, and the others also walked out of the Kunlun Domain and returned to the Martial Palace, and after hearing the news that the Great Demon King had disappeared again, they almost fell down.

"I don't understand the feelings of our old men at all. ”

A few old people smiled wryly, and a big living person disappeared again and again, and his heart couldn't stand it even if his heart was a little worse.

Of course, this news also spread to the outside world and into the sea of stars.

"Could it be that the Great Demon King has rushed to the sea of stars?"

"Hmm, I seriously doubt that there is a Great Demon King in the group of Heavenly Saints and others who intercepted and killed the Heavenly Saints a few months ago?"

"Thinking about it too much, those are three saints, it can already be determined, do you want to say that the Great Demon King has become a saint in a hundred years?"

There are quite a lot of such discussions in the sea of stars.

At the bottom of the sea, the Great Demon King is completely ignorant of the news from the outside world, and he is still contemplating and cultivating.

Flesh and bones are glowing, purple, and the strength is many times more terrifying than I don't know how many months ago.

The True Dragon Body Refining Secret Technique, on the basis of the Purple Gold Body Refining Secret Technique, pushed his physical strength to the peak.

Moreover, the most important thing is that the fit between the True Dragon Body Refining Secret Technique and the Divine Thunder Secret Technique is even more terrifying, the Divine Thunder Secret Method and the True Dragon Refining Secret Technique complement each other, and the physical strength of the Great Demon King is much stronger than the physical strength possessed by simply cultivating the True Dragon Refining Secret Technique.

Rumble!!

On this day, this sea area boiled, and then, this small world-like true dragon's lair completely collapsed, and a terrifying aura burst out.

"The realm still hasn't set foot in the pseudo-saint, but the strength has improved too much. ”

The Great Demon King whispered, his breath was restrained, and he looked like an ordinary person on the outside, but if anyone could detect the power of his physical body, he would definitely feel palpitations, because what was hidden in this seemingly ordinary physical body was the power that could explode a planet.

"It's time to head to the sea of stars. ”

Then, the Great Demon King whispered and looked at the sky, as if he could see the scene of the forbidden sea of stars in the universe.

Not long after, the elders of the martial palace saw the Great Demon King, as if they had seen a ghost.

"Stronger again?"

An old man muttered like this, looking the Great Demon King up and down, how long has it been, the Great Demon King's breath has become more and more terrifying, even him, he feels that his heart is about to collapse when he looks at it.

Of course, this is also related to the fact that the Great Demon King did not completely lose his breath.

Undoubtedly, this time the martial palace shook again.

Subsequently, the Great Demon King did not hesitate and said his thoughts.

"Are you sure that you will go to the Forbidden Star Sea? Many saints of the race are joining forces to ambush you. ”

A group of old men are very worried, although there are three gods to strike first, it is difficult to guarantee that those people will not be ruthless again, because such a deterrent is far from enough to deter those big clans.

"Rest assured, I'm sure. ”

The Great Demon King smiled, and he felt that he had an explosive power in his body, and even against the Holy Saint, he could kill him.
