The strength of the Black Demon Dragon was far higher than that of the Netherworld Emperor Realm, which was beyond the scope of Gao Yun's comprehension, and even his insignificant clone had reached the peak of the Heavenly Netherworld Realm, just one step away from the Emperor Realm.

If it hadn't seen it with its own eyes, it wouldn't have been able to believe that a person in the early stage of the Earth Netherworld Realm would be able to cross a big realm plus seven or eight small realms and defeat an opponent at the peak of the Heaven Netherworld!

Looking at Gao Yun, who was covered in scars and bloodstains in front of him, the gray-clothed old man and the black demon dragon who were waiting quietly on the side were secretly surprised.

After more than half an hour, Gao Yun slowly opened his eyes and regained his vitality.

However, his face was still a little pale, although his soul power had recovered six or seven percent, but the loss of origin soul power was irreparable.

But then again, if he didn't use his Origin Soul Power, maybe he wouldn't have any hope of defeating his opponent at all, after all, the gap was too far away.

Seeing him stand up, the black dragon immediately said in a deep voice: "I didn't expect you, this kid, to be able to pass the trial of the first layer of the Nether Demon Dragon Technique!"

In the originally cold and indifferent black dragon's voice, there seemed to be a trace of humanized emotional fluctuations.

Gao Yun smiled miserably and said, "It's just a narrow victory, and it has also shaken the foundation of cultivation, and the gains outweigh the losses." ”

Origin soul power is a small group of special soul power that a netherworld cultivator has in his body when he is first born, and it is hidden in the core position of soul power in the dantian, which directly determines the achievements that can be achieved by soul power cultivation, once lost, even if he absorbs more foreign soul power, it is irreparable.

Hearing this, the black dragon snorted lightly, obviously disdainful of Gao Yun's statement: "It's just a trace of origin soul power, it's not a big deal, you can exchange it for the first layer of the Netherworld Demon Dragon Technique for just such a small price, you kid has made a lot of money!"

A look of surprise suddenly flashed in his eyes, Gao Yun looked at the black dragon steadily, and secretly wondered in his heart: Although there are some suspicions of Wang Po selling melons and boasting about herself, this demon dragon is unfathomable after all, and it should also be relied on to praise the Netherworld Demon Dragon's trick so wildly.

Just as he was thinking about it, a black aura suddenly poured out of the black dragon's body, and it instantly condensed into a lifelike small black demon dragon image in mid-air.

Before Gao Yun could react, the small black dragon suddenly let out a low dragon groan, which immediately turned into a subtle black rainbow light, roaring down from mid-air, and instantly shot into Gao Yun's body.

The black light instantly diffused, enveloping Gao Yun's entire body, but he didn't notice any discomfort on his body, and at the moment he was hit by the black light, he could clearly feel a majestic sea of information, frantically pouring into his mind.

Gao Yun closed his eyes, and the vast amount of information that rushed into the mind of the quick wanderer.

"Netherworld Demon Dragon Technique, condense the dragon form, between the feet, the heavens and the earth shake!"

More than a dozen ancient fonts gradually converged and took shape in his mind, and between the strokes, a vast and majestic momentum was revealed, and a sense of extremely oppressive majesty permeated out.

"This is the Nether Demon Dragon Recipe!" Gao Yun muttered to himself, looking at this row of ancient characters, his heart surging.

Just a few words made him feel a heavy pressure, so how terrifying this soul trick was.

Gao Yun immediately sat down cross-legged and entered the cultivation state.

And outside his body, the black light did not dissipate, but formed a curtain of light, enveloping his entire body.

Once you enter the cultivation state, time flies and flows quickly, and before you know it, two hours have passed.

At this time, the gray old man suddenly appeared, stood a few feet in front of Gao Yun, stood with his hands tied, looked at Gao Yun's slightly trembling body, and frowned slightly.

"It seems that the loss of Origin Soul Power still has some impact, and I am afraid that I will not be able to fully comprehend the first layer. ”

"Hehe, it's rare to see you care so much about someone!" The black dragon who was waiting on the side looked at the old man, his huge eyes narrowed slightly, "Is there anything worth paying attention to about him?"

"Although there is, I don't know exactly what it is...... old man muttered, "There seems to be an extremely obscure ancient aura on him, but I still can't understand what it is when I look closely. ”

Hearing this, the black dragon was suddenly surprised, and turned its head to look at Gao Yun, but no matter how it scanned, it couldn't detect the existence of the strange aura that the old man said.

However, the dragon clan is originally known for its strength, and it doesn't have a deep understanding of things at the soul level.

Seeing that the black dragon showed a puzzled look, the old man immediately waved his hand, shook his head and said, "Don't care too much, it's just some extremely subtle aura, so weak that you have to meditate and concentrate to sense it, and it shouldn't have much impact on his cultivation path." ”

The old man suddenly changed his words, and his eyes looked at the black dragon sharply: "By the way, it seems that you forgot to send him the blood of your demon dragon, right?"

The demon dragon was already a little weak-hearted, and when he heard this, he immediately said, "What about this...... I just want to see how it goes, maybe he can complete his cultivation without the blood of the demon dragon, hehe!"

The old man cursed secretly in his heart, and said solemnly: "Since he has passed the trial, he should get the reward he deserves!"

The little thought that the demon dragon wanted to get away with was suddenly shattered, and looking at the old man's cold gaze, even he was secretly trembling in his heart.

"Okay, okay, I'll give it to you!"

Although the magic dragon was infinitely beautiful in his lifetime, he is now just a wisp of remnant soul, and everything depends on the face of this old man. If you sin against him, there will be absolutely no good fruit to eat.

Take 10,000 steps back, even if you go back to the time when it was in its prime 10,000 years ago, the prestige of the Demon Dragon Clan is still not as good as the super sect where this old man belongs, and the strength of this old man back then is even more stable than himself.

Hurriedly agreeing, it immediately opened its huge mouth, and a dark black light cluster with countless light spots flickering around it immediately swept out of it, like a meteor in the air.

In the cluster of light, faintly, there was a high-pitched and loud sound of dragon groaning, and there seemed to be an extremely strong fluctuation spreading.

Looking at the light cluster, sensing the powerful fluctuation that was not unfamiliar, the old man twisted his beard and nodded slowly.

With a soft sound of "boom", the black beam of light instantly swept across the sky, and finally rushed directly into Gao Yun's body, and suddenly the black light curtain around him faintly fluctuated, and the surface of Gao Yun's body in it shook slightly wildly, and a low roar of pain that was hard to suppress but unbearable seeped out.

The old man looked at Gao Yun's painful appearance, but he was not moved at all, and said to himself in a calm tone: "The blood of the demon dragon is the foundation of cultivating the Netherworld Demon Dragon Technique, the body of ordinary humans is too fragile and difficult to accommodate it, and now it has been given to you as a reward, as for whether you can accept the blood of this demon dragon, it depends on your own ability." If you can't even pass this level, then the first layer of your Demon Dragon Recipe can only learn at most a skin, and you won't be able to exert its power at all, and as for the later layers, you don't have to think about it. ”

The demon dragon on the side looked at Gao Yun's distorted face with blank eyes, and sighed: "You said that I just can't bear the blood of this demon dragon, but you have seen a lot of previous trialists, relying on the cultivation and powerful artifact protection thrown out of countless pills to pass the first layer by luck, but even the blood of the demon dragon can't be absorbed, and this precious blood is wasted in vain." You must know that their cultivation is all much higher than this kid, and some of them have reached the late stage of the Heavenly Netherworld Realm or even the peak, but they are not defeated and died. ”

It originally only had a few dozen drops of demon dragon blood here, and if it gave one drop, it would be one drop, and the previous dozens of painful lessons had taught it that it was too difficult for humans who were congenitally deficient to pass the level of absorbing demon dragon blood.

"That's what you said absolutely," the old man snorted lightly, and nodded at Gao Yun rather disappreciatively, "Didn't his father absorb the blood of the demon dragon?" ”

The demon dragon twisted his body uneasily: "When his father came in, he was in the Heavenly Netherworld Fourfold, more than a big realm higher than him, and he was not able to absorb it perfectly, so that when he passed the second layer of trials, he bumped and bumped, and the third layer couldn't get through." Seeing him in such pain really makes people sweat. ”

Just as they were talking to each other, one dragon, and two wisps of ghosts, Gao Yun, who was trembling slightly, was trembling slightly, but there was an incomparably chaotic scene inside!
