Gao Yun had previously accepted the cultivation technique of condensing the dragon form of the first layer of the Nether Demon Dragon Technique in his mind, and he was resting and concentrating on his understanding, and soon, a gray light and shadow in the shape of a black dragon was virtualized in his mind, but no matter how he tried, he found that no matter what, he couldn't make this light and shadow fly up like a real dragon.

Dozens of attempts, and the same number of failures.

Looking at the black dragon phantom scattered in front of him, Gao Yun sighed secretly.

He was by no means lacking in perseverance and tenacity, but looking at the phantom that was gradually dissipating, he felt that there seemed to be something missing in order for this dragon form to truly have a hint of a real dragon!

But he searched the contents of the formula, but found no trace of error.

"Could it be that I really lack comprehension and can't comprehend this method?" After trying it a few more times, even Gao Yun, who had an excellent heart, couldn't help but feel depressed, and thought secretly.

At this moment, he suddenly felt that there was a terrifying energy that was so huge that it could not be described that suddenly rushed into his body.

"What's going on?

Gao Yun's body suddenly tensed, and as his mind dived into his body, he was suddenly stunned by the scene in front of him!

I saw a black light cluster suspended in the air, and streams of dark and lightless energy were like black dragons, surging out of the light clusters, and the trace of terrifying energy that escaped was like a rising tide, sweeping wildly through his body.

These energies were pervasive in his body, and unbearable pain suddenly surged from all over his body.

Gao Yun's body was as tight as a tense bowstring, the green tendons on the surface of his skin shook like dragons, and a low roar of pain came out of his throat.

The black energy that came out of nowhere rushed into his body like magma, and the blood in his place was completely volatilized at the same time, and the meridian muscles along the way were all in shambles.

When the blood in Gao Yun's body seemed to be decomposed by the intense heat, the sharp pain in his heart suddenly spread rapidly from his whole body along the nerves, hitting Gao Yun's mind like a strong wave.

His body twitched violently at this time, beads of sweat fell like raindrops, and the low roar coming from his throat was no longer like a human voice, but more like a wild beast roaring in pain, and between his black pupils, there were even swollen and bloody streaks climbing out.

"Ying Huang, since you don't have the blood of the Demon Dragon in your body, you can't actually cultivate the Nether Demon Dragon Technique, and this drop of Demon Dragon's blood will help you improve your physique. However, the dragon blood will completely eliminate and reshape the blood in your body, this process is extremely painful and dangerous, if you can't hold on, just tell me, I will forcibly interrupt the process, although you will still be seriously injured, but at least it is better than death. ”

The old man's solemn voice suddenly sounded in Gao Yun's ears.

Hearing this, he frowned secretly.

Although his current internal condition was very bad, it was absolutely impossible for him to give up his hard-earned cultivation opportunity.

"I, I...... Not...... ...... thing" Gao Yun, whose face was distorted and horrified, and whose face was covered with beads of sweat, reluctantly replied in his heart as he resisted the terrible pain from everywhere.

"Click, click!

As several low but piercing voices came out of his body one after another, Gao Yun could clearly feel that the blood in his body was being shattered inch by inch by the huge energy gushing out of the black light cluster, almost violently!

The feeling of clearly feeling the blood evaporating was so painful that it almost made people collapse, but at this time, Gao Yun was clenched with his fists, clenched his teeth, and even had a trace of blood spilling from the corners of his mouth, trying his best to hold on.

Even with such intense pain, he still had no intention of giving up.

Although he still doesn't know much about his physical condition, and he still can't figure out the relationship between Gao Yun and Ying Huang's two identities, he is very clearly aware that no matter whether he is Gao Yun or Ying Huang now, there is one thing that cannot be changed, that is, he has to do his best to overcome the life and death difficulties in front of him!

The drastic changes in Gao Yun's body continued for a whole hour.

With a bang, the blood in Gao Yun's body was finally wiped out, and at this time, Gao Yun's body finally collapsed, almost unable to support it.

Immediately after, just as all the blood in Gao Yun's body volatilized, the black light cluster suddenly exploded.

Immediately, black energy with vast oscillations surged out, turning into a huge black cloud in Gao Yun's body, and a strange scene also happened at this time.

I saw a dark cloud full of black energy, and immediately like raindrops falling, sending a trace of liquid black water droplets towards all parts of Gao Yun's body. And an extremely obscure and complex bloodline qi immediately flowed in Gao Yun's body.

With the slightest flow of this strange aura, the energy of the black liquid quickly merged into Gao Yun's body, and soon entered the bloodline, replacing Gao Yun's original blood in his body, becoming his new source of strength.

The color of these fresh blood gradually changed to a dark red close to ordinary blood, but with a slight black dot that was almost invisible, which was essentially different from his original blood.

A majestic and mighty energy full of ancient aura suddenly continued to pour out from Gao Yun's body, like a fountain, quickly spurting away towards the surroundings.

The gray-clothed old man and the demon dragon, who were chatting on the side, suddenly sensed the powerful momentum erupting from Ying Huang's body, and they were immediately stunned and turned their heads to look at him.

The black dragon's body trembled violently, not from panic, but from a slight excitement that had not been seen for a long time.

From the coercion emanating from Gao Yun's body, it sensed extremely violent but extremely familiar fluctuations!

"This, this is ......" Looking at Gao Yun, who was sitting upright with his eyes closed, the black dragon spoke incoherently in an extremely rare manner, "Perfect inheritance! A human can do this with just the blood of a demon dragon, it's too rebellious!"

Side. The old man's face was extremely solemn, indicating that his shocked mood at this time was no less than that of the demon dragon.

After looking at it for a long time, the old man slowly breathed a sigh of relief, and said in a calm tone: "After waiting for so long, it was finally not in vain!"

In their gaze, Gao Yun's trembling gradually subsided, and finally stopped completely.

Suddenly, a dragon's groan shook the entire cave.

"Roar"!

I saw a faint black light, and a shocking sound came out.

Gao Yun no longer had the pain he had before this time, but felt extremely happy.

I saw that his figure was shocked, and it actually soared from the black light that filled the space, and instantly suspended steadily in mid-air.

At this time, he was filled with a faint black light above and below his body, and these black lights were condensed on the surface of his skin, vaguely showing the shape of a simple dragon pattern. Behind him, there was a faint shape of a coiling dragon, looming.

Gao Yun lowered his head slightly, looking at the surface of his body with some excitement, and as his body moved, he could clearly feel the terrifying power in his body that was surging like ocean waves.

Now he is undoubtedly much stronger than before!

"This is the change that the blood of the demon dragon brings to the body!"

The corners of Gao Yun's mouth twitched, and the excitement in his eyes flashed.

Now he can clearly feel that the power he has is probably comparable to the strength of the original Netherworld Combat Body, and if he uses the Netherworld Combat Body now, he doesn't know what terrifying level his strength can reach!

His mind moved, and he immediately fell to the ground, trying to urge the Nether Demon Dragon Technique.

Suddenly, he felt that all the muscles in his body seemed to be full of strength, and with a slight stomp of his legs, the entire cave space suddenly shook violently.

"Between the feet, the heavens and the earth shake"!

Just when Gao Yun was excited, a sound suddenly came from the side.

"It's really good to comprehend the first layer of the Netherworld Demon Dragon Technique so quickly, and also perfectly inherit the blood of the Demon Dragon......"
