The light of the pentagram was constantly changing, like a lightning that had gone off, making a hissing sound, and the shattered light was constantly bursting out from the prohibition, a bit like a precursor to a great explosion.

A stream of light came, as if the air was distorted, and the images of the five people were deformed, just like the images in the convex lens, there was an unusually strange feeling.

The five of them had solemn faces, and after only walking a few meters, they stopped and did not dare to move.

This is a sixth-level formation, even if they are all spiritual realm powers, they don't dare to act at will, once they trigger a formation attack, it is enough to kill them. It seems to be only 20 meters away, but in fact it is even more difficult to walk than the ends of the earth.

"It's time, they have entered the outer depths of the core formation, and it is impossible to harm you inside the formation. Xuyunzi said, "You hurry in, and then find the teleportation location, and I will pass on the outer formation changes to you." ”

As he spoke, a spiritual sense came.

Inside the spiritual consciousness is a messy bunch of disorganized, but it seems to faintly reveal some kind of regular lines, and it is constantly changing, like a dynamic labyrinth, revealing complex and profound meanings.

In the center of the line, there is a faint red line that runs through the beginning and end of the line, which seems to have an unusual meaning.

If other monks saw it, they were afraid that they would have a big head, but Xu You's forbidden foundation was already quite clever, and he could see at a glance that this was the structural change of the outer layer of the sixth-level formation.

As for the red line, it is the safe forward route deduced by Xuyunzi, and at the end of the red line, it is the teleportation point of the formation.

The sixth-level formation changes from time to time, so the forward route also needs to be adjusted from time to time, if there is no certain forbidden craft, even if you get the safe route of Xuyunzi. It is also impossible to move forward in the formation.

Xu You operated the Spirit Technique, and completely interpreted the content of the Spirit Sense in an instant, and when he looked at the five-pointed star formation, he already knew the changes in the peripheral formation.

Suddenly, his heart moved, and he felt that the content that Xuyunzi had cracked was somewhat familiar. Looks like I've seen it somewhere.

At the same time, the feeling that had been faintly felt before became clear.

As he pondered, he took a step forward and walked towards the core formation.

Originally, he was going to enter the core formation, and the five-pointed star end was the best entrance, but the five corners were already occupied by the five Spirit Sky Realm monks, and Xu You could only find a random spot to enter.

Fortunately, the security route deduced by Xuyunzi is flexible and free, no matter where it is.

The five Spirit Sky Realm cultivators all saw him slowly walk into the core formation. Although he was surprised how this junior was able to get here, there was some disdain on his face.

Even if they were still trembling in this sixth-level formation, walking on thin ice, a junior with a spiritual artistic conception would dare to break into the formation? I'm afraid that if they can't take a single step, they will be broken out by the formation, and they will end up with no bones left.

But the next scene surprised the five people.

I saw Xu You walking into the core formation at will, although his steps were extremely slow, he did not stop like them. And the forbidden streamer did not change at all. It seems that no intruder was detected at all.

The five of them were stunned, and watched in a daze as Xu You gradually went deep into the center of the formation. I couldn't believe my eyes.

That's a sixth-level formation, it's the peak of the late stage of the Spirit Sky Realm, and I don't dare to say that I can spend it safely, why does this junior walk like his own back garden.

In a moment, Xu You walked seven or eight meters away, which had already exceeded the progress of the five people. But the footsteps have not stopped.

Only then did the five of them react, looking at each other, and couldn't help but be shocked and angry.

The young monk, in particular, was even more pale.

They never expected that at the critical time of competing for the Yuan Shen Pearl. Someone else will be involved, which is tantamount to adding a sudden and unforeseen change to their plans.

Who is this spiritual realm junior? How did he get here? What method did he use to enter the sixth-level formation at will, but he was not attacked by the formation? Could it be that his target was also to run towards the ancient tomb master in the coffin and compete with us for the treasure?

One question after another appeared in the minds of the five people, but none of them had answers.

If Xu You is the same as them, he is the power of the Spirit Sky Realm, after all, the cultivation is there, and he can get through the previous hurdles and come inside, but he is just a junior in the spiritual realm.

Whether it was the previous Void Tribulation Killing Array, the Fourth-Level Phantom Formation or the Fifth-level Ladder Formation, this junior could easily be killed a hundred times in seconds.

But the truth is that even the Tomb's most advanced sixth-level core formation has not been able to get this junior now.

This is really a strange thing that the five spiritual light realm powers have never seen in their lives.

And now that they are in the formation, the five of them can neither ask questions nor attack, they can only watch Xu You keep moving forward, and their faces have become gloomy.

Xu You didn't care about it, and after walking fifteen meters, he stopped.

This is the end of the outer layer of the core formation, and it is also the limit of the deduction of the void cloud, and five meters further is the inner layer of the core formation.

It's like a thunder pool, if you go one step further, you will incur a fatal blow.

This is also the closest place to the Red Lotus of the Snow Mountain, which seems to be within reach, but the distance of five meters is equivalent to the separation of life and death.

"Why don't you go? Take one step further, and you can teleport out. Seeing him stop, Xuyunzi asked in surprise.

Xu You showed a thoughtful look: "I just watched you crack the outer layer of the core formation, and I always felt familiar, as if I had seen it somewhere." ”

Xu Yunzi couldn't help but laugh and said: "Can't you think about it again when you go out?" you have to think about it here, hurry up, if the sixth-level zombie awakens, I'm afraid that the formation will change." ”

Xu You didn't speak, and after half a sound, his eyes suddenly lit up: "I remember, old fellow, in the hall where I just entered the ancient tomb ruins, the screen engraved on it seemed to be the change of this sixth-level formation." ”

Xuyunzi was speechless: "That's what you've been thinking about all the way?" I have long known that the ruins of the ancient tomb are originally a whole, and it is normal for the beginning to echo the end from afar, and the hierarchy of the sixth-level core formation is engraved on the screen, which does not mean anything at all. ”

"That's not what I'm thinking, old fellow. Xu You's face showed a look of ecstasy, "I felt familiar with the contents of that screen before entering the ancient tomb, but only now do I remember that I had seen it before." ”

"You've seen it before? When have you seen it? The ruins of this ancient tomb have been buried deep in the snowy mountains. Xuyunzi said.

Xu You's spiritual sense moved, and he took out a silver jade slip: "You can use your spiritual sense to scan it, and you will know the way." ”

Xuyunzi's spiritual sense swept away, and he suddenly lost his voice and said, "This ...... This is the roadmap for cracking the core formation of the ancient tomb, including two layers, inside and outside, which is equivalent to the official key of the formation, how can you have it?"

"It was given to me by a friend before he died, and he begged me to return his body to his family, and then gave me this jade slip as a reward, and told me not to go on a rampage until I had enough strength. Xu You sighed.

The friend he was talking about was naturally Lei Chen, and this silver jade slip was also given to him by Lei Chen.

Afterwards, Xu You had seen the silver jade slip once, but his cultivation was too low at that time, and he didn't understand the prohibition, so he couldn't understand the content of the silver jade slip at all, so he left it behind.

When he saw the depiction on the screen of the ancient tomb hall, Xu You faintly felt familiar, but after being in danger all the way, he didn't have time to think about it, until he received the cracked content of Xuyunzi now, and then he remembered this silver jade slip all the way.

"How can this be ......" Even Xuyunzi was extremely shocked. The ruins of the ancient tomb that had just been born for a few months, the cracking content of the core formation had already been circulated, and it had also happened to Xu You.

It's unbelievable.

"This silver jade slip is very different from the white jade slip commonly used by monks now, it should be a thing of the past, my friend said at that time that it was obtained from an ancient tomb, it is possible that the ancient tomb has a certain connection with this ancient tomb, and many times, the degree of truth is far more bizarre than people imagine. ”

Xu You also felt incredible, thought about it and said.

"Anyway, little bastard, we really picked it up this time. Xuyunzi smiled, and there was uncontrollable joy in his voice.

With this jade slip, Xu You is equivalent to crossing the inner layer of the core formation like flat ground, and it is naturally easy to get the Snow Mountain Red Lotus.

Xu You smiled slightly, and began to absorb the contents of the jade slip, the first time he read this jade slip, it was like reading a book from the sky, but now it is not much more difficult than reading a comic book.

The five Spirit Sky Realm cultivators had been watching him closely, and they all breathed a sigh of relief when they saw him stop at the edge of the outer layer of the core formation.

As long as this junior can't enter the inner layer of the core formation, it will have no impact on their plans, after all, the cultivation is there, and the ants are ants.

Suddenly, there was a soft bang, and the vermilion coffin lid opened outwards automatically.

Seeing this scene, whether it was the five Spiritual Light Realm cultivators or Xu You, their faces changed instantly.

"That zombie is going to be ready to take the Snow Mountain Red Lotus, boy, are you ready? Xuyunzi's voice also became solemn.

"Ready. Xu Wei nodded and said, the spirit and spirit were running, and the ancient well in his heart was not wavering, and it was as calm as water. With his current forbidden manufacturing skills, absorbing the contents of the jade slip was only a matter of minutes.

In the blink of an eye, the inner changes of the core formation were all clear, and the thunder pool, which was originally insurmountable, had now disappeared.

Several Spiritual Light Realm cultivators took a few more steps forward with difficult steps, and after glancing at each other, they all offered the spiritual treasures in their hands.

As the lid of the coffin opened, a terrifying coercion came out of the coffin, as if a peerless demon king was slowly waking up, without deliberately blooming his breath, just the power made the wind and clouds change color. (To be continued......)
