When the words fell, Lu Yun's figure had already disappeared into the darkness.

In the cave there is only the promise of the passing water: "Don't worry, I will never forget." No matter what is requested, as long as I can do it, I will do my best. ”

In the dark, Lu Yun walked all the way along the tunnel.

From the moment he came here, Lu Yun sent out a wave of thoughts, constantly exploring the surrounding situation.

Unfortunately, this cave is extremely strange, and the mind wave is disturbed by something strange, and it is impossible to detect the secrets in the depths of the cave.

For this reason, although Lu Yun was surprised, he had no choice but to put away his mind and divine waves, release the Ruyi Heart Soul Sword, illuminate the surroundings with that red light, and use his eyes to see everything nearby.

The cave was very deep, and Lu Yun walked about a hundred zhang before he came to a wide underground cave, and three tunnels appeared in front of him.

Looking around, the Ruyi Divine Sword above Lu Yun's head roared across the four fields, and it only took a moment to circulate in this wide cave for a week, shining in every corner.

The stone walls here are a bit cold and damp, and it is surprising that some moss grows in the crevices of the stones, but there are no animals in sight.

Retracting his gaze and looking at the three cave doors, Lu Yun once again sent out a wave of thoughts, exploring the situation of the three tunnels.

Soon, the situation in a cave on the left came back, and the tunnel was very deep, with a strong and strange barrier at the end, apparently just a passage to another place.

The situation on the right also began to return after a while, and the result of the detection of the Mind Divine Wave was that there were many forks in it, and there were extremely strong interference waves interfering with the detection of the Mind Divine Wave, and there were several mysterious places in the cave.

However, the situation in the middle cave was blurry, and Lu Yun repeatedly increased the frequency of the divine wave of thoughts, but unfortunately he still couldn't find the slightest information.

There was something mysterious in it, capable of repelling all detection waves, so that Lu Yun could not do anything.

After pondering for a long time, Lu Yun walked towards the hole in the middle.

As soon as he entered the cave, Lu Yun couldn't help but shake his body, and a mass of high-speed airflow molecules surrounded him, making his senses useless, and his eyes couldn't see the movement in front of him clearly.

Stopping, Lu Yun calmed his mood for a moment, the whole body was full of golden light, and the supreme magic of Buddhism surged out, making a golden color within a few zhang nearby, isolating the strange air flow molecules.

Through the light of the Buddha, Lu Yun could roughly see things within three zhangs, and he moved forward with this.

After walking for about a stick of incense, Lu Yun suddenly found that there was a bright light in front of him, and couldn't help but speed up, and after turning three corners, he came to a cliff, and in front of him was an abyss hundreds of zhang away, and countless flashing dark green, dark red, and dark purple lights and shadows were flying and swimming in this abyss, emitting a faint light.

On the opposite side, hundreds of zhang away is a tunnel, where there is a strong light, making the cave door very dazzling.

Looking at everything in front of him, Lu Yun felt a little incredible.

This is obviously an underground cave, why is there an abyss of hundreds of zhang in the middle of this cave?

If it is a cliff between two mountains, then it should be cracked and there is light above.

But there's obviously no light here, it's like someone has hollowed it out, what's going on?

Also, this flashing light and shadow, according to the detection of Lu Yun's mind divine waves, is clearly composed of a gaseous substance, and it looks like the soul of the ghost domain on the outside.

At the same time, their trajectory also has a certain regularity, just like an unknown formation, blocking something and protecting something.

In the silence, Lu Yun stroked the Four Spirit Divine Beasts on his shoulders and said to himself, "Da Ling'er, don't you think there is something strange hidden here?" ”

Shaking his head, the Four Spirit Divine Beasts said, "This place is very evil, and there is a wonderful power that is interfering with me. In addition, as far as I know, there is a very strong force hidden here, but it has always been very obscure, as if it was wrapped in something, and it was not willing to be easily revealed. Also, there seem to be several different spaces connected to each other in a strange way. ”

Lu Yun was startled, glanced at it, and then returned his gaze to the flying light and shadow, and said softly: "No matter how mysterious this place is, I plan to explore it." Do you want to come with me, or do you want to stay here, or maybe have other ideas? ”

The Four Spirit Divine Beasts stared at the abyss and said, "I feel that there is some kind of powerful creature hidden under this abyss, and I plan to visit it for a while." If you're done, come back here to me, and I'll be here for you. ”

Lu Yun was silent for a moment, then nodded: "That's fine, you remember to be careful, don't get angry easily, otherwise I will be trapped here by you." ”

The Four Spirit Divine Beasts flew into the air and said proudly: "Don't worry, I have grown up now, and my control over my power has reached the realm of being able to retract and release freely, and it will never be the same as before." ”

Looked at it a few times suspiciously, although Lu Yun didn't believe it, he didn't say anything more, and the whole person flew towards the opposite side with the sword.

Behind him, the Four Spirit Divine Beasts let out a low roar, and their figures disappeared into the darkness.

In the mysterious cave, at this time, a crimson light crossed the abyss, and the target was directly aimed at a dazzling cave opposite.

When this red light flew nearly halfway, the flying light and shadow around it suddenly increased its speed, and in the blink of an eye, a strange bright brilliance was formed, forming a circular formation in the dim abyss, and countless layers of light and shadow were densely packed, like a sky full of stars twinkling and running.

Looking at all this in front of him, Lu Yun seemed very calm, because he had expected these things beforehand.

While releasing the Divine Wave of Mind to probe the mystery of this formation, Lu Yun slowed down and observed the movements around him.

At the same moment, those lights and shadows staggered and galloped according to different trajectories, and in the blink of an eye, a shuttle network of light appeared outside Lu Yun's body, and became more and more dense.

Feeling the pressure beginning to approach, Lu Yun's eyes turned, and then the golden light flashed around his body, and the supreme body protection method of Buddhism firmly protected himself.

After applying the defensive enchantment, Lu Yun's body began to flicker left and right, and according to the route detected by the Divine Wave of Thought, in a very strange way, it circled back and forth from time to time, turning in a roundabout way.

This lasted for nearly a stick of incense, and in the end, Lu Yun didn't break out, which made him extremely surprised.

Stopping, Lu Yun resisted the terrible pressure while thinking about the cause of the problem.

Since his debut, this is the first time that Lu Yun has been defeated by the formation, is it lucky in the past, or is it careless this time, or is it something else?

After thinking about it, Lu Yun gradually understood the problem, everything had a lot to do with the environment here.

As far as Lu Yun's analysis is concerned, the reason why the Mind Divine Wave did not find the correct route this time is mainly because this is the most mysterious place in the Demon Domain, and there is a mysterious force that invisibly lands Lu Yun's Mind Divine Wave, making it lose its previous accuracy.

For this reason, it is not surprising that this mysterious strange array cannot be broken.

After grasping the reason, Lu Yun put away his thoughts and divine waves, and the golden brilliance of his whole body instantly turned into a black demonic light, and the Demon Sect's "Heart Desire Without a Trace" was fully exerted, and suddenly the surroundings were filled with endless spiritual powers, and they were analyzing the movements around them at an extremely high frequency.

During the exploration, Lu Yun found that the spiritual power he sent out was also greatly repelled, and a force of similar nature was violently confronting it, constantly eating away at his true qi and preventing the spiritual power from extending outward.

After a while, Lu Yun finally chose to give up, because he found that this method would not work.

Facing the flying lights and shadows around him again, Lu Yun's face became a little serious, is this strange and unknown formation really that powerful?

The answer is no.

It's just that because it appears here, under the influence of the mysterious power around it, the consciousness of the person who broke the formation is disturbed, and it is difficult to concentrate, so he is powerless to crack it.

In silence, Lu Yun put away the magic light around him, and the whole person turned from bright to faint, and at this moment, he cast the "Void Trace" technique, trying to confirm the speculation.

Soon, the results came out, and Lu Yun obviously noticed that the powerful pressure around him could not hurt himself at all.

In this way, Lu Yun began to move, and the whole person was like a shadow, passing through that strange formation.

At first, Lu Yun was going well, but when he got close to the edge of the formation, the strange formation automatically shifted, and the power of his formation always trapped his figure.

Sensing that it still didn't work, Lu Yun had no choice but to display his mind again.

Who knew that this time, in the case of casting the "Void Trace" technique, it was unexpectedly easy to cast the Divine Wave of Thought, and soon detected the mystery of the formation.

For this reason, Lu Yun has learned a lot of things.

Passing through the abyss, Lu Yun came to the entrance of the tunnel, and he put away the Void Method.

Glancing at the cave, Lu Yun found that the light didn't seem to be close, because the light had been refracted and was already a little scattered.

Walking along the tunnel, Lu Yun took advantage of the light in the cave and found that there were patterns of beasts on the four walls from time to time, all of which were in some strange postures and rare forms, as if it was a long, long time ago.

After thirteen bends and a distance of about eighty zhang, Lu Yun finally came to the glowing place in the cave.

It's a magical being, with incredible miracles.

The cave is not as big as expected, only ten zhang wide.

However, the magic lies in the fact that there is a mysterious door in one of the stone walls of the cave.

It was a door made of crystals, which looked more like a mirror, and its surface was full of colors and sparkles.

Approaching this crystal door, Lu Yun found that on this mirror-like door, there were countless beast lights and shadows alternating on it, evolving into different shapes.

Sometimes it's one, sometimes it's two, sometimes it's three.

They are at war with each other, each showing their own power, and it is like a group of beasts fighting for supremacy.

After watching it quietly for a long time, Lu Yun said in surprise: "This is actually a hundred beast stunts, it's really amazing." Who is here to stay, and how is it going to evolve like this? ”
