With a chance to breathe, Lu Yun hurriedly took advantage of the victory to advance, and the magic trick after the fusion was launched with all his might, and after a series of moves, he finally stabilized the battle situation.

As the situation stabilized, Lu Yun's heart began to heavily, because he had already found that he had consumed too much True Yuan.

Although he has the "Heaven and Earth Wuji" technique, he can absorb the aura of heaven and earth while attacking, but in this case, his body is not there, he is not even a primordial god, but his consciousness is here, what can he do?

The danger was approaching step by step, Lu Yun knew it, but he didn't show panic.

Calmly analyzing the situation in front of him, Lu Yun concentrated on observing the attack moves of those light beasts, and always had a familiar feeling.

He had felt this before, but he was in a hurry and didn't have time to think about it, and then he analyzed it carefully, and he couldn't help but suddenly realize, and secretly scolded himself for being confused before, and almost died in it.

It turned out that the moves performed by these light beasts were exactly what Lu Yun had seen in the cave before, and he had also created a set of "Hundred Beasts Ling Tian" stunt because of this, but he didn't want him to forget it for a while, so that he was almost finished.

At this moment, Lu Yun's form changed greatly after understanding the situation, he put away his various tricks, and displayed the "Hundred Beasts Ling Tian" strange science, using the spear of the son to work as his shield.

In this way, Lu Yun successfully found the breakthrough point, and with the assistance of the "Hundred Beasts Ling Tian" stunt, after a long time, he finally broke through this level.

Looking back at the difficult journey, Lu Yun was full of emotion, everything was really fateful.

Without the previous experience outside the cave, and without the self-created "Hundred Beasts Ling Tian" peerless learning, even if he had the supreme magic technique, he would definitely not be able to break through this passage.

It's easy to say, but it's hard to imagine how clever it is.

If it weren't for fate, how could we talk about all this, if it wasn't for Lu Yun, would someone else be able to create a hundred beasts, find out the mystery of the crystal gate, and pass through this mysterious tunnel?

After a short period of contemplation, Lu Yun drove the long sword to move on, exploring the unknown mystery.

The passage in front of him was still full of colors, the difference was that there were fewer attacks from those light beasts, and there were more strange light runes.

Moving forward, Lu Yun was not fast, he was exploring whether these light runes were hiding any secrets or dangers, preparing for the next step.

Through the detection and analysis of the Divine Wave of Thoughts, Lu Yun felt very strange in his heart, these light runes seemed to be some kind of magic trick of the Demon Domain.

Lu Yun was very surprised by this, the magic that can be preserved in this mysterious other world is naturally not a simple thing, but who created all this, could it be said that these have existed since the formation of the Demon Domain, or did a genius of the Demon Domain design all this later?

Unable to guess the result behind this, and unable to understand these light runes, Lu Yun couldn't help but speed up, so as not to stay too much and dream a lot.

After passing through this section of the passage, Lu Yun came to a gray tunnel.

Standing still, Lu Yun analyzed the surrounding situation and found that there were many breaths hidden in this gray mist, as if countless small creatures were living in this gray mist.

These auras were strong and weak, but the boundaries were not obvious, indicating that there was not much difference between them, which reminded Lu Yun of a past incident.

I remember that before the Six Academies met the martial arts, Lu Yun entered the Absolute Yin Valley and encountered the mysterious Black Domain Secret Realm, and was attacked by countless qi before entering.

At that time, he thought it was some kind of monster or creature, but later he realized that it was some anger, and he never thought about it, and he didn't expect to encounter a similar situation here today.

At the beginning, the Absolute Yin Valley was a place where monsters gathered, and today this secret path is the most mysterious place in the Demon Domain, and the two have their similarities, so will the small breath in this be the same as that of the Absolute Yin Valley?

With a bit of speculation, Lu Yun first set up a defensive air shield outside the sword body, and then flew into it, waiting for the next result.

Soon, it could be said that in an instant, countless auras around him swarmed in, eating away at the pale cyan light around the long sword at an astonishing speed.

Sensing that the aura around him was also a kind of aura, and it was heavier than the demonic aura contained in the aura of the Absolute Yin Valley at the beginning, Lu Yun had already made a conclusion in his heart.

The strength of the Qi Theory in front of him was not very strong, but what was terrifying was its number, the speed at which it was eating away at the True Yuan, and the length of this tunnel.

If you want to pass through this tunnel, you have to constantly use the defensive air shield, one layer is eaten up, you have to add one layer, and if the ten layers are swallowed, you have to add ten layers, this is completely an endurance competition, and those who don't cultivate enough will never be able to break through.

Thinking of this, Lu Yun understood that time was of the essence, and the longer he stayed here, the more dangerous it would be, so he moved quickly, flying forward quickly, while thickening the defensive air shield outside his body, in order to cross this death passage as soon as possible.

As he walked forward, Lu Yun found that the tunnel was very long, and the defensive air shield outside his body had been broken through by the qi for fifty-three layers, but it was still gray in front of him, and there was no sign of breaking through.

Flying at a constant speed, the gray mist on both sides retreated at the same speed, coupled with the aura outside his body that had been eating away at the true yuan, and the gray mist around him, it felt as if it was not moving, and time seemed to have stopped.

Trapped in it, Lu Yun didn't feel it at first, but after a long time, he found that this tunnel actually gave people a sense of powerlessness and made people have a desire to give up.

It felt like a big fall into the sea, struggling in the endless water, and the feeling of despair and helplessness was so strong that it made people panic.

Thinking of this, a thought suddenly flashed in Lu Yun's heart, in this mysterious tunnel, in addition to this aura that eats away at the true yuan, is there some kind of power that consumes the will?

If so, could everything in front of you be an illusion, or that there is some kind of formation hidden in the gray clouds, and people will always wander in it.

With this guess, Lu Yun hurriedly urged the Divine Wave of Mind to explore the Quartet with its magical and mysterious power.

At first, the Divine Wave of Thoughts couldn't find anything, but then Lu Yun adjusted the frequency of the Divine Wave of Thoughts, expanding its range by ten times, so that after a short time, there was some information feedback, forming some useful information in Lu Yun's mind, and the analysis came up with certain results.

From what was detected, the gray mist as a whole was like life, and those tiny rays of air were only a part of its composition, controlled by it.

As for the situation outside the body, judging from Lu Yun's analysis and inference, there is no power to consume the will in this gray mist.

However, the surrounding qi was in accordance with a certain law, some of them were eating away at his true yuan, and some of them were united, forming a not obvious, but extremely effective defensive formation in the gray clouds, trapping Lu Yun in the center.

Because of this, after flying for a while, Lu Yun still stayed in the encirclement of the gray mist, and it was difficult to get rid of its troubles.

After finding out the reason for the trap, Lu Yun hurriedly stopped moving forward, thinking about how to deal with the crisis in front of him.

As far as the formation is concerned, Lu Yun can almost be said to have no difficulty because of the help of the divine waves, and the most important thing at present is how long he can support himself in such a harsh environment, and whether the consumption of the true yuan and the speed of breaking the formation can be grasped.

Thinking of the time, Lu Yun did not hesitate any longer, while exploring the principle of the formation to analyze its flaws, while adjusting the true element, and coordinating the distribution of defensive and offensive forces, he launched an action.

In the gray mist, I saw a flash of blue light, and after the long sword circled, the entire sword body vibrated violently, and the dark blue light on its surface flew like rain, turning into hundreds of magic swords after being a few feet away from the body, and with the control of the main body of the sword body, it began to be divided into four directions, forming a five-element sword array.

As soon as the sword formation was formed, the main sword body in the middle began to spiral and move, and its trajectory was very strange, always shooting out several times and then suddenly rushing back, maintaining a certain regularity.

All around, small magic swords crossed and shuttled, some outward and some inward, under the control of Lu Yun's mind, hitting the inconspicuous formation air mass in the gray mist, in order to find the hidden array eye.

It turns out that this so-called formation is that some qi rays are condensed together to form a relatively large air mass, and then a certain number of air masses run according to a certain direction, which forms the formation in front of you.

In the gray space, the dark blue light appeared and disappeared from time to time, accompanied by some sparks of collision, adding a bit of color to this calm space.

During the attack, Lu Yun mastered the principle of this formation through the understanding of the Mind Divine Wave, and easily found the way.

To this end, he urged the magic swords around him to advance with all his might, and violently collided with the air mass that formed the formation.

The sparks began to intensify, the blue light gradually flourished in the gray clouds, and the outer formation gradually collapsed under the attack of the magic sword, and finally saw a light sword break through the clouds, with a thick green smoke, and disappeared in the depths of the gray mist.

Breaking through the gray fog, Lu Yun appeared in front of a green tunnel in front of his eyes.

From a distance, the emerald green seems to be endless, but in the depths of the tunnel, there is a faint light and shadow.

Staring ahead, Lu Yun's heart was a little heavy, he had been in danger all the way, and the consumption of Zhenyuan was extremely high, and he could not predict whether he could pass through this mysterious tunnel for unknown reasons at this moment.

Inferred from previous experience, this seemingly peaceful passage in front of you is definitely more dangerous than before, in that case, who can know whether it is life or death?

In his contemplation, Lu Yun also thought of another point, that is, what is hidden in this cave, and why is it so dangerous along the way?

Previously, Lu Yun had actually thought about this problem before entering the cave, but in his original conjecture, even if there was danger, there would be at most one or two places in it, but who would have thought that it would be such a result.

Passing through the crystal gate, Lu Yun's consciousness attached to that look, fused with each other into a sharp sword, and after many hardships and dangers, he finally came to a green tunnel mouth.
