Yes, that's the dragon's groan. Yi Yunfei was in a desperate situation at this moment, and between his mouths, what came out of his mouth was no longer a human voice, but a very strange dragon groan.

This dragon roar was like rolling thunder, making many people instantly pale, like a sledgehammer, hammering hard into their chests and minds. Many people felt as if their breath was choked, and suddenly stagnated, their complexion changed greatly, and they coughed violently and kept dodging backwards.

It's a shock that goes straight to the depths of the soul, and makes one feel fear from the deepest part of the soul.

The imposing Ancestor of the Ying Zhao Division, his dark purple body suddenly trembled, and his huge eyes showed a rare expression of surprise. The kind of pressure that made Yi Yunfei completely irresistible suddenly retreated like a tide.

"What kind of exercise is this, how can it be so terrifying, how many hole cards does this Yi Yunfei have not taken out?" The Terran monks who were watching the battle thought that they had completely understood Yi Yunfei's methods, but at this moment, they doubted it again.

"If this voice is not mistaken, it should be the legendary dragon chanting. What kind of adventures did Yi Yunfei get? How could this kind of dragon groan come out of a human person's mouth? The dragon clan has long been submerged in the dust of history, and now only occasionally heard of the existence of this race in myths and legends, how did Yi Yunfei do it?"

As soon as the pressure around him was relaxed, Yi Yunfei took a greedy deep breath, and the aura as thick as a cloud and mist poured into his mouth quickly, and the exercises were running rapidly, and the acupoint space that was opened by him rotated like a whirlpool, and his body had become a black hole of aura at this moment, and countless aura frantically poured into his body.

In the human body, there are 12 meridians of the five internal organs (in fact, there are 24 symmetrical left and right). In addition, there is a "Ren Pulse" in the center of the front of the body, and a "Du Pulse" in the center of the back of the body, each with a special meridian that runs through the whole body. The acupoints of the human body arranged on these 14 meridians are called "positive acupoints", and there are a total of 365 points in total.

The 365 acupuncture points are absorbing spiritual energy, and its speed can already be said to be terrifying. The blackened clouds in the sky were all pulled by the hurricane formed by the fluctuations of this aura, showing a strange gyroscopic shape, slowly rotating.

Yi Yunfei knew that his cultivation was not enough, and he was working hard to impact. Just now, he had already felt that the barrier in his body had been opened, his divine soul and his physical body had merged, and the cultivation realm had reached the entry stage of the king realm, which was commonly called the stage of entering the void by human race cultivators.

If the human body is a container, the ascension of the realm can only be said to be that the capacity of this container has become larger. But if there is not enough energy to operate, the improvement of the realm will not bring much improvement in combat power.

What Yi Yunfei did at this moment was to fill his own container with a massive amount of spiritual energy. Only when the aura is absorbed sufficiently can he truly step into the realm of entering the void. Because of the existence of the acupoint space, the amount of aura required for his advancement was extremely terrifying.

When an ordinary Terran monk ascended to this realm, it may be enough to accumulate his own spiritual energy. But Yi Yunfei can't, the path he chooses, every time he improves his realm, he needs the support of aura that many people can't use in their cultivation for a lifetime.

If it weren't for the scorching temperature of the Zong Yun card emitting in his arms at this moment, and the massive aura surging like an endless amount, he was afraid that he would not know that the Year of the Monkey and Ma Yue would be able to truly enter the realm of emptiness.

However, it was precisely because of the huge amount of energy required for his advancement that when he truly stabilized the realm, his combat power was only afraid of the monks of the entire king realm, and no one dared to attack him.

Every cell in his body was expanding, and there was infinite power bouncing in the cells, like a piece of refined steel, constantly being forged. His skin exuded a jade-like luster, the bones in his body emitted a glowing white shimmer, and his veins emitted a scorching temperature, like magma flowing.

The essence blood of Emperor Yu in the space of Tanzhong, after being silent for many days, moved again, and this time, his appearance did not make Yi Yunfei feel very powerful. Instead, it was very calm and emanated, constantly blending into Yi Yunfei's rolling blood. It is not known what kind of effect this integration will have. But no matter whether the result was good or bad, Yi Yunfei couldn't control it, because after Emperor Yu's essence blood entered his body, it was automatically triggered every time, and it was not under his control.

Yi Yunfei stood still, and no one from the Terran monks watching the battle made any sound. Including the three generations of ancestors of the Demon Clan's Yingzhao Department who confronted him, the wings raised at this moment were also quietly frozen in mid-air, his face was hesitant, and his eyes flickered.

The ancestor of the demon clan summoned by Cao Jiema in this way, I don't know if it was because of the influence of the way it appeared, or for some other reason, this huge purple figure has not made any sound since it appeared. After stagnation at this moment, everyone could only guess what he was thinking by his gaze and facial expressions. However, the information available to these two channels was so scarce that no one could guess why he stopped his attack at this moment.

On the other hand, Yi Yunfei, the blood oozing from his body was strangely sucked back along the pores at the moment, and the luster on his skin became more and more conspicuous. The embarrassed image of being covered in blood under the suppression has long disappeared, but there is an inexplicable aura on his body, which looks calm and unremarkable, but it makes people dare not look at it directly.

The aura was too sufficient, and in just a few minutes, Yi Yunfei felt that his body was filled with unprecedented power, and his eyes like lightning suddenly looked towards the demon ancestor in the sky.

His eyes flashed like lightning, but his mood was very calm, and he didn't have the anger that he imagined after being suppressed for a long time. It's just that this calm gaze made the body of the demon clan ancestor in mid-air tremble suddenly, and in the disbelief gaze of everyone, including Cao Jiema, he shrank back slightly.

No one could understand what was going on, only Qin Chengcheng, who was standing with his hands in his hands not far away, with a slight chuckle on his delicate face like a girl. Although she didn't understand why the dragon qi on Yi Yunfei's body was so strong, she was probably the only one who understood the mystery.

The spirit of the ancestor of the demon clan in the sky was not afraid of anything else at this moment, it was the dragon qi on Yi Yunfei's body that was rich to the extreme. Yi Yunfei absorbed the dragon soul in the trial space, and then obtained the nine-infant dragon qi given to him by Qin Qingcheng, which was like an introduction, drawing out the dragon qi on his body and infusing the entire divine soul.

What he has now is said to be dragon energy, but I am afraid it is not enough to describe it, because a large part of his divine soul is a dragon soul.

This is not comparable to a little dragon energy, and ordinary people are too far away, and they may not have such a strong feeling. But facing his demon clan ancestor, he felt paralyzed all over his body, if he wasn't still sensible, he could see that Yi Yunfei's cultivation was still a big gap compared to it back then, but he was afraid that he had already turned around and ran away at this moment.

"Ancestor, kill him, he will definitely be the enemy of our clan in the future!" Cao Jiema felt this strange atmosphere, and his heart was uneasy for a while, and he screamed.

This is his last hope, he saw Yi Yunfei's improvement, originally before Yi Yunfei was promoted, he didn't have any confidence to defeat him, and at this moment, he felt more and more that there was no chance. His roars and screams didn't make the Demon Ancestor move, which made him extremely anxious.

The few remaining demon clan demon king monks behind him were also pale one by one, feeling the end coming.

Although he didn't understand what had happened to the ancestor of the demon clan at this moment, Yi Yunfei naturally would not give up such a good opportunity, he stepped out, and a massive aura suddenly emanated. He's about to make a move, and in the face of this existence that everyone seems to be invincible, his choice is still not to escape, but to shoot head-on.

"Boom!" Between the dimly lit heaven and earth, a snowy light suddenly appeared, and the thunderstorm that had been gathering in the sky for a long time finally landed. Yi Yunfei has crossed the great realm of entering the realm of gods at this moment, and the thunder tribulation will naturally not be absent.

Originally, Yi Yunfei thought that it would take some time for the Thunder Tribulation to gather, thinking that he would first solve the battle in front of him and then face the Thunder Tribulation. Unexpectedly, the gathering speed of this thunder tribulation was much faster than he imagined, and in a short period of time, it landed.

The huge thunder and lightning with the thickness of the water tank were extremely fast, and almost the moment the light appeared in the sky, it had already fallen on the top of Yi Yunfei's head, and he didn't have any time to react at all, and he was already struck by the thunder and lightning.

The loud bang was deafening, and there were no small thunderbolts like silver in the entire heaven and earth, this time the thunder tribulation was much more powerful than any thunder tribulation that Yi Yunfei had ever experienced.

The Terran monks felt that their fragile nerves were no longer enough, and this great battle was too much for them to expect. It can be said that it is a step and three folds, and now they are almost numb, and now even if a flower blooms on Yi Yunfei's body, they probably won't feel how strange it is.

However, the feeling of worry still rose in everyone's hearts, and the power of this thunder tribulation was not only something that Yi Yunfei had never encountered, but even many monks had seen it for the first time. They whispered one by one again, looking at Yi Yunfei with worried eyes.

Yi Yunfei was not as worried as everyone was, he was hit deep underground by this thunderstorm, his body was straight, his face was calm, and his emotions did not change in any way. At this moment, everyone's nervous eyes were cast on his face, and his face was full of surprise to find that his expression was actually a little enjoyable.

Silver-like thunder and lightning swam rapidly on Yi Yunfei's steel-like body, and as time passed, these thunderbolts continued to weaken and dissipate.

"Did you see clearly, he actually absorbed this thunder and lightning!" Someone stared wide-eyed, and after continuous confirmation, he suddenly screamed loudly.
