"Of course there is more than one! If I'm right, there should be eight colors! As for the number of them, there are countless and they are powerful!" said Xiao Shuai with certainty.

"You guess?" Mu Yu squinted at Xiao Shuai.

Xiao Shuai scratched his head embarrassedly and smiled: "Okay, it's my feeling." Anyway, it's a familiar feeling, the old man must have brought me to this place, and he should have been to the other side. ”

Xiao Shuai pointed to the other side of the formation, that is, beyond the breach.

"What the hell is on the other side?" Mu Yu still didn't understand.

Xiao Shuai said solemnly: "It's a very nasty thing, anyway, you should quickly repair this seal! ”

Mu Yu looked at the formation pattern breach in front of him, and then looked at the boundary of this formation. This formation is a spherical shape, and the crushed stone blocks that have just come in are wrapped in it, and the diameter looks like it is at least a thousand meters.

The diameter of this formation crack in front of him was only one meter, which was insignificant for the entire formation.

But it was such an insignificant breach, but it made Akatsuki, an ugly flesh-winged horned monster, escape, and almost made a big mistake.

Mu Yu carefully examined the structure of the formation in front of him, deduced it in his heart, and finally shook his head slightly.

"It's a bit difficult to fix this formation. ”

Although he had obtained all the inheritance of the Heavenly Dao, and even learned many of the formations of Father Deadwood, it did not mean that he knew all the formations in the world. Even if he had the Formation Hall at the moment, it would be impossible to control this formation.

Although the Array Hall and Array Rune Stone claim to be able to control all the formations in the world and crack all the formations, this is relative to some common formations.

The complexity of the formation in front of him was beyond Mu Yu's imagination, just like the Nine Heavens Sealing Demon Array in his body, it was not an existence that he could control.

What's more, this formation is still under the sword shadow dust wind, and his formation technique is much higher than Mu Yu.

Mu Yu cautiously approached the breach in the formation, and the closer he got to this gap, a feeling that made his heart palpitate came, and finally even made him feel a little irritable in his breathing.

The aura outside the formation was very powerful, and he felt like he had pressed a stone in his heart, and the closer he got to it, the heavier the stone in his heart became.

He moved to the breach of the formation, carefully looking through the breach to see beyond the formation. All I could see was a void of darkness, and in the darkness there seemed to be some shadows flowing quickly, and even mixed with some white light, which was so fast that it flickered and disappeared, and it was impossible to see what it was.

When Mu Yu reached out towards the breach, a huge squeezing force surged towards him!

"It's ...... Heaven and Earth Barrier?"

Mu Yu looked at the terrible squeeze in surprise, and remembered that when he returned from the second heaven to the third heaven, he endured the squeeze from the two worlds through the wood spirit, and that terrifying feeling was only fresh in Mu Yu's memory.

"Heaven and Earth Barrier? is the rat hole you talked about last time?" Long Teng didn't go to the Double Heaven together last time, so he didn't know what it was like at the beginning.

"What rat hole, big earthworm, can you have a little culture?" Xiao Shuai scolded.

"Didn't you say you came back from a hole?"

Ryuto curiously stretched out his claws, trying to get closer to the breach, but Ki Yu quickly pulled it back.

"Don't stretch your hand out, this will destroy your hand in an instant," Mu Yu didn't think that Long Teng was as thick as Xiao Shuai.

"Heaven and Earth Barrier! If I'm not mistaken, passing through here should be another world!" Xiao Shuai said seriously.

"Heaven and Earth Barrier, is this also the gateway to the Double Heaven?" Mu Yu asked puzzled.

The existence of the Reiki Eye is due to the imbalance in the concentration of Aura between the Triple Heaven and the Triple Heaven, which causes a gap in the weakness of the two worlds to appear, connecting the two worlds. When Mu Yu didn't teleport the jade pendant, he relied on the wood spirit to return to the Triple Heaven through the barrier of heaven and earth.

"It doesn't have to be a gateway to the double heavens, there are other worlds. The aura eye is just a form of passing through the Heaven and Earth Barrier, and there are other different ways to break through the Heaven and Earth Barrier and travel back and forth between the two worlds. The Heaven and Earth Barrier is a difficult thing to explain, it can be understood as the wall of two worlds, some places are very weak, some places are very vast, so vast that you can't imagine it. ”

Xiao Shuai was confused when he explained this, it was like a fool who had forgotten many memories, and some things needed to be recalled slowly.

It thought for a long time and continued: "The weak place is as thin as a piece of paper, and it is easy to form an aura eye, and the aura eye is a passage that can be passed quickly. And in the vast expanse of the place, you don't know where the exit from the other end of this ethereal wall is, it is even longer than the whole world, if we venture into it, we will definitely get lost in the barrier of heaven and earth, if we can't find the exit, it will be doomed. ”

The barrier between heaven and earth was compared to a piece of paper by Xiao Shuai, which is an unacceptable statement. But even with the thickness of a piece of paper, in Xiao Shuai's explanation, even a cultivator in the Tribulation Period would not be able to break it!

"Didn't the flesh-winged horned monster come in through here?, which means that this barrier is not very wide, should we go and see the world it is in?"

"No! it must be disgusting in that world. Xiaoshuai shook his head.

Mu Yu didn't have that idea either, although he had a wood spirit that could guarantee survival in the Heaven and Earth Barrier, and might even reach the world where Akatsuki was, but the purpose of his coming here was not to explore other worlds.

And he felt strange that if Akatsuki came in through the barrier of heaven and earth, then when did the Yellow Spring corpse water form? And why did the people of the Ghost Gate know that someone from another world was coming, and send someone to answer it?

Mu Yu's hand touched the surrounding formations, carefully inspected the aura in the formations, and compared them with other undamaged formations, he found that the cracks in this formation had not been destroyed for a long time, but in the gradual expansion, it was obvious that the shattering of one place would affect other places, and maybe in a few years, this formation pattern would disappear.

What will happen then?

Mu Yu conveyed this question to Xiao Shuai, who thought seriously for a long time, and said: "If the formation pattern disappears, in fact, there will be no accident, didn't you find that the stones on the rock wall in the Mass Burial Valley are very strong? We didn't break any rocks back and forth, only a few rocks on the Mass Burial Valley were broken by us." ”

Mu Yu nodded, the structure of the Mass Burial Valley was indeed quite hard.

"When the Mass Grave Valley looks down from the sky, it looks like a crack, and this crack is actually the crack in this world! Entering this crack is equivalent to entering the barrier of heaven and earth, but the barrier of heaven and earth here is not as thin as the aura eye that communicates the double heaven and the triple heaven, so once we blindly enter, we will be lost in the barrier of heaven and earth. ”

After a pause, Xiao Shuai continued:

"Maybe the white-bearded old man used the formation to confine the heaven and earth barrier to such a deep place in order to hide this dangerous place. The pile of rubble is also very hard, although there are gaps between them, but they are indestructible, they are enough to resist the squeeze of the barrier of heaven and earth, maybe it was made by the white-bearded old man! After the Akatsuki self-detonated, it produced a huge force, and inadvertently triggered some kind of protective measures. ”

Mu Yu was surprised, the terrifying destructive power of the Heaven and Earth Barrier Mu Yu had seen it, he had experienced it once when he was in the Double Heaven, and at that time he felt that he was not even as good as a speck of dust in front of this ability, and he still had this idea.

And the master was able to forcibly restrict the heaven and earth barrier to the bottom with a formation, what level did the master's strength reach in the past?

"But this formation is so complicated, how did the flesh-winged horned monster crack it? Its little pediatric formation didn't even notice that I had set it up, how could it have the ability to crack such a powerful formation as Master?" Mu Yu still didn't quite understand.

And even if he is asked to crack this formation now, he may not be able to make such a big hole. The pattern here is too mysterious to ponder.

"I suspect that the Flesh-Winged Horn Monster may have wanted to come from another world, but was blocked by this formation. Thinking about it, such a disgusting guy is inseparable from the dead, and the Yellow Spring corpse water happens to be corrosive and can absorb spiritual power, so it should be made by relying on the Yellow Spring corpse water to corrode a small hole, and then relying on the small hole to control the dead people above. Xiao Shuai guessed.

Mu Yu carefully calculated the distribution of the aura of the entire formation, and then calculated the corrosive ability of the Yellow Spring Corpse Water, he felt that with that corrosive ability, it would take at least a few hundred years to drill a small hole, and this flesh-winged horned monster actually had such a lot of patience!

But this is not the time to praise people's patience, since there is a guy running over, it's hard to say if a second one will come, he has to help the master repair this formation.

If you want to repair a formation, you must first learn this formation and be familiar with the role of each spirit pattern carving line in this formation, otherwise once the spirit pattern you portray conflicts with the master's formation, it is very likely to aggravate the damage of this formation, and even put yourself into it.

"Master, you don't teach me the formation, but in the end it was me who helped you repair the formation, and I don't know what happened to you now?" Mu Yu sighed.

Master arranged this formation to hide the rift in the Triple Heavens, but also to prevent monsters from other worlds like Akatsuki from invading the Triple Heavens. He had given so much for the peace of the Triple Heaven, but now he was in prison and was nowhere to be found.

Xiao Shuai shook his tail: "I hope the old man with the white beard is okay! Anyway, let's plug this gap first!"

The array patterns in the distance kept shining, and the inscriptions were also circling rapidly. But those strange streamers dimmed as soon as they turned around the gap, and the entire formation continued to decline.

Mu Yu didn't understand this complicated formation, he needed to calculate the general layout of the entire formation according to the distribution of these inscriptions and formation patterns, which was a very arduous process and very difficult for Mu Yu.

But Mu Yu and Xiao Shuai would not have thought that in the Heaven and Earth Barrier, which was far away from the periphery of this seal, a streamer of light quickly shuttled through the Heaven and Earth Barrier, and it seemed that they didn't care about the coercion of the Heaven and Earth Barrier at all, as if they were taking a leisurely walk in it.

This streamer faintly looks like it's actually a figure!
