The Demon Dragon bloodline is the foundation for the existence and reproduction of the Demon Dragon Clan, and the significance to the Demon Dragon Clan is self-evident, Gao Yun has been staying in Huoyun Dragon City these days, and gradually has a general understanding of the Demon Dragon Clan.

The Demon Dragon Clan was actually located in an independent space that Gao Yun did not understand, and its territory was vast, not inferior to the Six Realms, or even much broader. Moreover, apart from being recommended by the few dozens of Demon Dragon Secret Realms in the Six Realms, this space does not seem to have any intersection with the Six Realms where Gao Yun is located.

Aside from the Nether cultivators who were recommended to come like Gao Yun, the number of clansmen in each clan of the Demon Dragon Clan alone could be calculated in the hundreds of millions!

If you add the people who came from the nether, then I don't know how many there are.

The cultivators of the various clans within the Demon Dragon Clan have an extremely long lifespan, a cultivator with a lifespan of tens of thousands of years, there are not many dozens of heirs, and if this continues, it will grow at a geometric rate, and it is easy for the number of people to exceed 100 million, not to mention that the Demon Dragon Clan has existed and multiplied for hundreds of thousands of years, which is much longer than the history of the Six Realms that Gao Yun knew.

With so many young heroes, it is difficult to imagine if they want to stand out among them.

After the assessment was over, Gao Yun immediately returned to his cultivation room, sat cross-legged on the warm jade bed, and secretly calculated the number of days he had come to this Fire Cloud Dragon City.

The speed of time here is ten to one relative to the world in the sky, and when Gao Yun left, he planned to spend no more than one hundred and fifty days here to learn all the two sides of the Netherworld Demon Dragon Technique, the two artistic conceptions, the destruction artistic conception, and the devouring artistic conception, and then go back to continue the unfinished business of Ying Huang.

And now, nearly eighty days have passed, and the artistic conception of destruction has not been completely broken, and time is getting more and more urgent.

"It seems that the situation is a bit bad......" Gao Yun's face condensed slightly, if this trend continues, I am afraid that when the time limit of one hundred and fifty days comes, he will be able to break through the destruction artistic conception at most, and if he wants to impact the next more difficult devouring artistic conception, I am afraid that there is not enough time, and his time is running out.

"Then there is only ...... I will absorb the essence blood of the demon dragon right now and improve my comprehension of the power of the fire origin. Gao Yun muttered to himself, secretly made up his mind, and held the jade box of the demon dragon's essence blood in the palm of his hand.

He has now completed the assessment of the headquarters, and he can go back at any time, but the speed of comprehending the power of the origin of the fire system in Huoyun Dragon City is faster, and most importantly, Gao Yun also has to break through the Destruction Artistic Conception and Devouring Artistic Conception, he doesn't know how far his strength has to be improved to ensure the completion of Yinghuang's last wish, in this case, only by trying his best to improve his strength to the limit, and then facing all kinds of difficulties and obstacles, the certainty of success is greater.

Holding the demon dragon essence blood in the palm of his hand, through the surface of the crystal transparent jade box, Gao Yun could vaguely feel the simple and mysterious aura coming from the crystal.

The jade box was only an inch in size, and the demon dragon essence blood sealed in it looked extremely viscous, showing a perfect spherical shape.

Gao Yun slammed his palm on the jade box, and with a sudden shock, the jade box immediately cracked with countless spider web-like cracks.

Immediately, as soon as the palm of his hand was inhaled, the demon dragon essence blood obediently flew into Gao Yun's palm.

The blood of the demon dragon essence was extremely viscous, and when it fell on Gao Yun's hand, it still condensed into a flat ball, like mercury.

There is no doubt that the Demon Dragon Clan itself is a high-level existence suitable for dual cultivation of the Law Body, and they have a strong physique. There is a vast amount of energy in the body, and not only that, but they themselves are more in line with the artistic conception rules of the origin of heaven and earth than human beings, or in other words, they are simply part of the origin differentiation.

Gao Yun's fingertips condensed the aura into a knife, and his face calmly slashed the skin on his arm, allowing the blood to flow out. Then, he pressed all the demonic dragon essence blood into his broken skin.

A burning sensation. It was as if a fire was burning in his arm, and it was as if Gao Yun had sprinkled a corrosive solution in his flesh and blood, but this pain was nothing to Gao Yun, who was accustomed to all kinds of pain.

Under the strong recovery force, the wound on Gao Yun's arm quickly healed, so this ball of demon dragon essence blood was sealed into Gao Yun's body.

The demon dragon essence blood, with extremely strong vitality, as soon as it enters Gao Yun's body, it begins to frantically assimilate and devour Gao Yun's bloodline, if it does not have enough strength, not only can it not absorb the demon dragon essence blood, but will be eaten by the demon dragon essence blood and die, becoming the nourishment to nourish the demon dragon essence blood!

Gao Yun silently operated the aura, and according to the basic method of the Netherworld Demon Dragon Technique, the Demon Dragon Essence Blood circulated over and over again in the meridians, and an invisible force enveloped the Demon Dragon Essence Blood, firmly suppressing it in it.

Gao Yun closed his eyes and immediately entered the cultivation state, and waves of invisible thought fluctuations emanated from his mind, and the origin flame aura of the surrounding space immediately flowed into the meridians in Gao Yun's body, slowly running according to the route of the basic method of the Netherworld Demon Dragon Technique.

At this time, in the soul source qi of Gao Yun's heart vein, the internal space slowly rotated, forming an energy vortex, constantly devouring the violent energy contained in the demon dragon's essence blood.

With Gao Yun's current strength, absorbing the essence blood of the demon dragon can be said to be no danger or danger, and it is only a matter of time before it is completely absorbed.

One, two, three......

Five days passed, and Gao Yun's body became more and more bright red and blazing, and as for Gao Yun's body, he fell into a strange state.

Originally, it didn't take so long to absorb the essence blood of the demon dragon, and Gao Yun would enter the meditation for five days because while absorbing the essence blood of the demon dragon, he comprehended the origin of the fire system contained in the essence blood of the demon dragon.

At this time, taking advantage of the opportunity to absorb the essence blood of the demon dragon, Gao Yun carefully sorted out the things he had comprehended, and verified them one by one with the Dao Zhili in the pattern of the fiery red planet in the source qi of the soul, and unconsciously, the carving on the surface of the fiery red planet was becoming more and more perfect, and Gao Yun's understanding of the power of the origin of the fire system was also improving rapidly.

On the fifth day, Gao Yun felt that the fiery red planet within his soul source qi seemed to be condensed again, and he was on the verge of transformation, and his cultivation seemed to have sensed a layer of separation, and he was about to break through to the emperor realm!

Gao Yun was overjoyed in his heart, after absorbing so much demon dragon essence blood, coupled with the comprehension of the power of the origin of the fire system, he was finally about to break through from the peak of the Heavenly Netherworld Realm to the long-lost Netherworld Emperor Realm!

Before entering the Treasure Hall, Gao Yun's cultivation was at the peak of the Heavenly Netherworld, and now in just over a hundred days, he was already about to break through to the Netherworld Emperor Realm, which was indeed an astonishing cultivation speed.

"Finally, it's time to break through to the Emperor Realm!"

Gao Yun's heart was shocked, he closed his eyes, gathered all the spiritual energy in the meridians into the dantian, and concentrated on breaking through.

Gradually, a spiritual qi cyclone formed within his dantian, and as more and more spiritual qi vortices were infused into it, the qi rotation speed became faster and faster, and the entire dantian was covered with a faint layer of blood red.

Two hours later, in the cultivation room where Gao Yun was, a fierce aura storm was stirred.

In Huoyun Dragon City, the aura of heaven and earth in the cultivation is extremely rich, but after all, the space between cultivation is limited, and it can't withstand Gao Yun's crazy absorption, and soon most of the aura in the space is absorbed by Gao Yun.

However, the cultivation room was originally designed to help cultivation, and the original designer had already considered a similar situation, after the concentration of spiritual energy dropped significantly, the formation between cultivation would naturally extract the spiritual energy of heaven and earth from Huoyun Dragon City for cultivators to use.

As a result, Gao Yun's cultivation began to gradually devour the nearby aura.

In the Triple Loft of Fire Cloud Dragon City, Fire Cloud made Fire Lotus quickly get the news, and these days, she has been sending people to pay attention to Gao Yun's situation.

"Gao Yun's cultivation room began to devour the aura power around him, and it seemed that this little guy was about to break through. The fire cloud made the fire lotus stand up and look through the window at Gao Yun's dwelling.

"Haha, it should have broken through a long time ago, he had comprehended the cultivation stone slab for so many days, plus he had absorbed so much demon dragon essence blood, his breakthrough speed was already slow enough!"
