The master of the formation hall was really "interested" and set up the formation with Xu Ke.

In the eyes of the Formation Hall Master, being able to follow Xu Ke to set up the formation together is a good learning opportunity. Not only was he interested, but he also planned to select some disciples to accompany him.

Xu Ke directly refused!

How can you say that this is also a "military secret", right?

Even if the people selected by your Formation Hall Master can be trusted, who knows if they will inadvertently reveal any secrets?

Hearing Xu Ke's opinion, the Formation Hall Master also felt that it was inappropriate, and immediately dispelled the idea of calling a few disciples to accompany him.

"I originally thought that it would be a good opportunity for them to let your disciples learn from you."

The Formation Hall Master smiled awkwardly, "Now that I heard you say this, it is indeed my desire to diverge, and I really have to keep it a secret." ”

Therefore, the master of the Formation Hall dispelled the idea of taking people to the Filthy Land, and just let a few selected disciples come to meet Xu Ke, which can be regarded as letting them get to know Xu Ke.

"Meet the Master of the Sinon Palace."

Immediately, several disciples of the Formation Hall came to meet Xu Ke.

"You're welcome, please get up."

Xu Ke stretched out his hand to help and motioned for everyone to get up.

Among these disciples of the Formation Hall who came to see him, Xu Ke saw Peng Zhengqing at a glance.

At this moment, Peng Zhengqing is already an inner disciple of the Formation Palace. This guy, in the formation, is really talented.

After the disciples saw the salute, they retreated one after another.

The Formation Hall Master walked up and smiled at Xu Ke, "Do you know Peng Zhengqing?" I noticed you just gave him an extra look. ”

"It's not just acquaintances."

Xu Ke said with a smile: "The first time I came into contact with the formation, he taught me. ”

What is the first contact formation?

It should be the first time you have come into contact with the formation in your "life", right?

As for Peng Zhengqing's Xu Ke formation, it may have been taught by Peng Zhengqing, but ...... Does Xu Ke still need to learn? Mighty reincarnation!

"Peng Zhengqing, this kid, has a good life!"

The Formation Hall Master sighed, "He is a spiritual root with a complete range of five elements, if he had been placed before, he would not have had a chance to become a true disciple at all." ”

"Now...... You have turned the 'Five Elements Gong' into the 'Five Elements True Method'. Thanks to you, many disciples of the Five Elements Spirit Root in the Formation Hall will have a chance to be promoted. ”

"I'm also a member of the sect, of course I have to contribute to the sect!"

Xu Ke smiled and didn't say much on this topic.

Subsequently, the master of the Formation Hall drove the take-off boat, carrying Xu Ke to break through the air and escape together, all the way to the filthy land of Hengduan Mountain.

A few hours later, the ship reached a filthy place deep in the Hengduan Mountains, hovering in mid-air.

Xu Ke stood on the bow deck of the flying boat, looked around, and used the "Heavenly Eye" to re-observe the flow of spiritual energy and the trend of the earth's leylines with the "Heavenly Eye".

After making sure that there was no problem with the Formation Hall Master's map, Xu Ke motioned for the Formation Hall Master to descend the flying boat and land on a mountain peak near the Filthy Land.

The flying boat stopped, but Xu Ke and the Formation Hall Master did not get off the ship, but sat down in the cabin and continued to discuss the formation plan.

"This is the Purification Array I have arranged in the underground rift, and it is marked with the orientation of all the array base nodes and the operation data of spiritual power."

The Formation Hall Master opened a scroll of array diagrams and discussed it with Xu Ke.

Xu Ke and the Formation Hall Master both knew technology, and the two of them compared the terrain map and the purification formation map, and began to discuss how to modify the formation and how to adjust the formation base nodes.

said that it was a discussion, but in fact, it was Xu Ke who gave a plan for arranging the array, and the master of the formation hall asked Xu Ke about the difficulties of this arrangement plan.

In fact, the technique of the Formation Hall Master is not bad.

It's just that limited by the spirit root attributes, he is only very proficient in the formations of light and fire, and the other formations can only be said to be average.

After an hour of discussion, the two of them have drawn a new formation diagram of the readjusted formation plan.

"It's time to start!"

Xu Ke smiled and said to the master of the Formation Hall: "One person is responsible for a piece, hurry up and finish it." ”

"Hehe, no problem!"

The Formation Hall Master smiled and nodded, and took out a bunch of formation base magic weapons from the storage bracelet, "Bounded by the cracks in the ground of the Filthy Land, the north belongs to me, and the south belongs to you." ”

"Good!"

Xu Ke put away the formation base magic weapon, and with the help of the magic weapon "Mixed Yuan One Qi Primal Rune", he drove away like a real person in Jindan, and flew up through the air.

"Tsk! Even the magic weapon is there! ”

The Lord of the Formation Hall watched Xu Ke fly through the air, and couldn't help but sigh: "Who is the foundation building cultivator who can refine the magic weapon?" That's amazing! ”

Subsequently, the Formation Hall Master also took advantage of the retreat and flew towards the north of the Filthy Land, and according to the formation map drawn before, he began to lay down the formation base magic weapon.

With the ability of Xu Ke and the Formation Hall Master, it is not too simple to lay down the formation foundation magic weapon.

In less than an hour, the two of them had finished arranging the formation base magic weapons everywhere.

The two converge at a crack in the Filthy Lands.

Next, it's time to adjust the purification array that was originally arranged here.

With the array diagram drawn by Xu Ke, it is also very simple to adjust the purification array.

Merely...... Xu Ke was startled by the filthy aura that was isolated in the purification array.

"It's so scary?"

Xu Ke couldn't help but be stunned when he saw that after the formation was adjusted, he was churning endlessly in the brand-new Mixed Yuan One Qi Great Array, like a pitch-black ocean.

This is the first time Xu Ke has seen the filth with his own eyes! The scene in front of him was beyond Xu Ke's imagination.

"Scary? Where does this go? ”

The Formation Hall Master shook his head, "The filthy aura in the underground ruins, that's what it's called scary, no, it's not just scary, it's terrifying!" ”

"Say, what is this filthy breath?"

Xu Ke opened the Heavenly Eye, staring at the churning filth in the great array, but he couldn't see anything.

The Heavenly Eye encompasses the spiritual energy, demonic energy, and demonic energy, but it can't see the true face of the filthy qi, which makes Xu Ke frown.

"What else could it be?"

The corners of the Formation Hall Master's mouth twitched, "An extremely high-realm existence, I don't know what kind of creature it is, because he was looking for someone to take revenge, but the enemy was already dead, so he pulled a bubble of on someone's grave, causing the entire Hengduan Mountain to be polluted, and more than twenty Jindan Demon Kings died." ”

"I'm not asking about that."

Xu Ke had already deduced from the fact that the corruption technique could solve the filthy qi and that this filthy qi was dung.

The filthy qi is not "qi", it does not belong to the spiritual energy, demonic energy, but a substance, similar to "smoke".

"Smoke" is not gas, but countless tiny particles.

What Xu Ke wants to know is, what is the material composition of filthy gas? Why is there such a terrible force of erosion and pollution?

Well, this brings us to the origin of the material composition.

"If you want to know what the filth is, go in and have a look!"

The Formation Hall Master had a little ill-intentioned smile on his face, everyone has been in, but you haven't been there, of course, I have to pull you into the water and let you taste that too.

"This ......"

Xu Ke was a little moved, but he was not very reluctant. Who wants to go to the dung pit and smoke it once?

"You haven't seen the underground ruins yet, have you? Just go and see it. There was a large hall that was still intact, and a bronze coffin. The bronze coffin was magical, and the filth could not be eroded. ”

The Formation Hall Master was instigating Xu Ke to go into the "dung pit" again.

"Oh? And a bronze coffin that is not corroded by the smell of filth? ”

Now Xu Ke is really a little interested. The filth cannot erode the bronze coffin, and the truth contained in it must be extraordinary, and it is necessary to see and understand.

"Okay, I'll go in and have a look!"

Xu Ke naturally knew that the Formation Hall Master was instigating him, which was like if he was unlucky, he wanted to pull others into the water, otherwise his heart would be unbalanced.

Merely...... Have you forgotten that I have told you the way to deal with filth?

I don't want to go in, it's just a psychological effect.

"Come, I'll take you in."

When the Formation Hall Master heard that Xu Ke wanted to go in and have a look, he had a feeling that the conspiracy had succeeded, so he hurriedly got up and took Xu Ke down towards the crack in the ground.

Because there is a large purification array to isolate the filthy qi, the road from the underground crack to the underground ruins is clean, and there is no filthy qi permeating.

Merely...... Although the filth was gone, the residual smell still did not dissipate.

Xu Ke frowned, stretched out his hand, and with a wave of his hand, the magic weapon "Mixed Yuan One Qi Primal Rune" turned into a halo floating behind his head, and the dark green aura of the corruption technique was like a light curtain, surrounding his body, dispelling the peculiar smell.

This made the Formation Hall Master slightly stunned, and then he remembered...... The sect's method of purifying the filthy qi is still given by Xu Ke!

Well, Banmen got the axe.

The Formation Hall Master laughed dumbly, he originally wanted to tease Xu Ke with a prank, but he forgot that the methods to deal with the filthy qi were all made by Xu Ke, what could this embarrass him?

A flash of spiritual light flashed, and the Formation Hall Master activated a purification talisman and stretched out his hand towards Xu Ke, "Go this way, just go straight." ”

The two of them walked all the way along the underground passage, and soon after, they came to the entrance of the underground ruins.

A layer of formation light curtain covered the entrance of the ruins, isolating the surging filthy aura inside.

"That's all I have to go here."

The Formation Hall Lord smiled at Xu Ke, "I didn't dare to enter without preparing enough purification charms." ”

"It's a bit of a hassle, but it's not a problem."

Xu Ke looked at the pitch-black, as if there was no day on the other side of the light curtain, and he was also a little surprised.

A lump of Xiang polluted the Hengduan Mountain within a radius of thousands of miles, and also smoked a bunch of Jindan Demon Kings to death, which is really outrageous!

What kind of terrifying and weird creature is the existence of pulling this tuo Xiang?

Turning his head to look at the Formation Hall Master, Xu Ke said, "I'll go in and have a look, please wait outside for a while." ”

"No problem."

The Formation Hall Master nodded, "Call me if there is any situation, and I will immediately drive the big array to answer you." ”

The big array was all arranged by me, if there is any situation, I will directly activate the big array.

Xu Ke arched his hand towards the Lord of the Formation Hall, and then walked towards the light curtain at the entrance of the ruins, and waved his hand to release a spiritual power, seeping into the light curtain.

The big array was all arranged by Xu Ke, so naturally he would not stop Xu Ke.

A spiritual power was shot out, the light curtain swayed slightly, and Xu Ke's figure passed through the light curtain and entered the land of ruins.

Through the magic weapon "Mixed Yuan One Qi Primal Rune", the Mixed Yuan One Qi Great Array that had just been arranged was connected, and a steady stream of spiritual power was transmitted, protecting Xu Ke in the purification light curtain, completely unaffected by anything.

Well...... It cannot be said that there is no effect, at least the psychological effect.

The surrounding filth is as black as ink, as if walking in the dark deep sea, which makes people feel creepy.

Of course, Xu Ke didn't care about this feeling at all, the feeling he cared about was...... Am I wading into a manure pit?

Such a dark environment has no effect on Xu Ke's heavenly eye, and he can still see the surrounding scene clearly.

It was in ruins, and there were broken rubbles everywhere.

Among the broken tiles and ruins, there are also some high-grade spiritual treasures.

It's just that these spiritual treasures have all been smashed into pieces, and they have been eroded by filthy qi and completely turned into garbage.

Advancing all the way along the ruins, Xu Ke came to the only well-preserved hall among the underground ruins.

At the entrance of the main hall, a monument is erected.

This stele is a stele composed of various spiritual materials, which are randomly kneaded into a ball.

The above line of tense text shows what happened. In the words, there is also an extremely terrifying atmosphere.

Xu Ke glanced at it, and his eyes were stinging because of the dazzling aura on the words. This made Xu Ke quickly look away.

This glance also made Xu Ke see something clearly.

The residual breath on the text is obviously demonic. Therefore, the terrifying creature that pulls this soaring mass is a powerful demon.

Walk around the monument and enter the main hall.

Xu Ke saw that all kinds of furnishings and utensils in the hall were all high-grade treasures, at least all of them were Yuanying-level utensils.

It's just that after being eroded by the filthy air, these treasures have all become filthy things.

Unless someone can lay down a single mind, use the filthy qi as the source, cultivate the Dafa of filth, and still keep their own soul intact, then they can harvest a lot of treasures.

This world ...... No one can do that, right?

The corners of Xu Ke's mouth twitched a few times, and he continued to move forward.

Ahead is a huge copper coffin.

At the head of the copper coffin, above the lid of the coffin...... It's the source of filth!

In the bronze coffin, it is not only the source of filth, but also the cleanest place.

Because the bronze coffin is shining with spiritual light, it is doing its best to dispel this filthy breath. It's just that the source of filth is on the bronze coffin, and it can't be expelled at all.

The source of filth and the aura of the bronze coffin formed a strange state of equilibrium, both fighting each other with all their might, but no one could help anyone.

So...... This gave Xu Ke a chance.

Xu Ke used the eye of heaven to observe the aura of the bronze coffin and observe the source of filth, and it would not be counterattacked, which is very suitable for exploring the essence of the two.

The filthy gas, Xu Ke still can't understand it for the time being, he only knows that it is dung, but he doesn't know its essence.

However, the bronze coffin is bright, and Xu Ke can understand it.

This is Reiki.

Although the essence of this aura is extremely high, far from being comparable to ordinary aura, no matter how profound and subtle it is, the essence of aura will not change.

Under Xu Ke's heavenly eyes, in the confrontation between spiritual light and filth qi, a peculiar "spirituality" is shown.

If I had to describe it, there seemed to be a feeling that these auraes ...... It's like being alive.

This big guy must be dead, and he must be completely dead, otherwise the terrifying demon wouldn't have pulled a piece of Xiang and left.

Since he is completely dead, why does the aura carry a "feeling of being alive"?

The soul and spiritual power are integrated, and the will runs through the mana of the whole body, which is ...... The law has a primordial spirit.

Although the big guy is dead, and although his soul has been dispersed, his remaining mana still bears the imprint of his will.

It's not a remnant of a divine soul, it doesn't have any consciousness at all, and it doesn't have any wisdom, it's just a spiritual power that "has instinct".

Xu Ke's eyes lit up, this is an excellent research material!
