Li Mu once imagined that the demon cultivator who was caught in the Demon Prison Mountain would be very miserable.

But when you actually see it, you will know that the cruelty of reality is far more cruel than you imagined.

No, to be precise, it should be the means and mental techniques of the Demon Suppression Pavilion, which are far more cruel than imagined.

In addition to being treated as a slave and squeezing demon cultivators, there are also many requirements, which are used as cultivation raw materials to support the cultivation of the Heavenly Masters of the Demon Suppression Pavilion, and use [Qianyuan Creation and Transformation Skill] on a large scale to cultivate and improve cultivation, after Li Mu came to the immortal realm, it was the first time he saw it.

Demon cultivators with special bloodlines and certain cultivation were tortured by the most cruel means, so that in the midst of great pain, fear and anger, they released the maximum energy of the individual, and then were absorbed by the Taoist priests, and finally directly squeezed into dried corpses, piling up dry bones everywhere!

"What are you looking at? It's not the first time I've been here, and I'm a little nimble. ”

Mu Tianshi scolded.

Li Mu didn't speak, lowered his head, drove the flying ant vehicle, and went deep into the prison area.

The further you go inside, the more eerie, bloody, and terrifying the scene becomes.

On the stone pillar torture frame, dry bones were hanging, and the demon cultivators who had not died long ago, had just died, and had not yet died, were nailed to them, and blood flowed down the stone pillars, leaving black mottled marks.

There are also barbed gabions, imprisoned dry corpses, extremely miserable, half-human corpses, with animal characteristics, obviously tortured to death by the most cruel means, the pain they endured before death, so that their faces are hideous like the devil who wants to crawl out of hell for revenge.

Mountains of bones hundreds of meters high are undulating.

They are all made of the white bones of demon cultivators.

The bones of different kinds and creatures are piled up, and the light blue and dark purple ghost fires loom in the pile of bones.

When the yin wind blew and whistled by, the bones made a strange wind roar, as if countless angry and unwilling souls were roaring and cursing in unison.

Li Mu felt that his three views had been subverted.

Although the Demon Town Pavilion has always been oppressing demon cultivators, which is a well-known thing, Li Mu did not expect that the darkness and cruelty in it would reach such an extent.

And that's just the periphery of the prison area.

Crossing the walls of white bones, Li Mu followed Mu Tianshi to the real heavy prison area.

The dense prison fortress is like a vicious beast crouching on the scorched earth, towering and immovable.

In every prison fortress, there are demon cultivators who are constantly tortured.

According to Master Mu Tianshi's instructions, Li Mu sent pieces of immortal grass and pills to different prison fortresses, and the miserable and terrible pictures inside made Li Mu feel his scalp tingle for a while.

He saw that one by one, demon cultivators were like trees, bound and fixed and planted on the torture rack, constantly tortured, to obtain energy, and the blood was constantly extracted and refined into blood pills.

In order to prevent them from dying, the jailers would constantly heal their wounds, inject energy, and hang their lives with elixirs and sacred herbs.

This reminded Li Mu of the incident of live bear bile extraction that once caused an uproar on the earth, and the pharmaceutical company fixed the live bear in a cage, inserted a hose into the bear's gallbladder, and continuously pumped bile into the medicine...... After the exposure, public opinion was in an uproar and it was finally banned.

And now, the means of the Demon Suppression Pavilion are the same.

More cruel.

This time, the delivery trip ended quickly.

After Li Mu finished delivering all the pills and fairy grass, he controlled the flying ant vehicle and left.

This is the first time he has come to the cell area, but unfortunately he is not close to the rumored thunder prison, which is expected, there are still two days before the ten thousand demons attack the mountain, Li Mu does not have first aid people, the most important thing now is to figure out the terrain of the entire prison area, the prohibition of formations, the number of patrols, and the rules, and when you do it, it will be smoother.

After returning to Baicao Garden, Li Mu was undoubtedly driven to do all kinds of chores again, and there was no time to catch his breath.

Until nightfall.

Li Mucai was given a three-hour break.

Locking himself in the room, making it seem as if outsiders were cultivating against time, and then leaving a phantom clone, Li Mu left Baicao Garden as soon as possible, and then entered the prison area.

Familiar with the road, with Li Mu's current cultivation and methods, he quickly sneaked into the depths of the prison.

Crossing the walls of white bones, Li Mu came to a huge skull.

The skull thousands of meters high is roughly similar to a human skull, but there are three bulges on the forehead, like a bone like horns, one eye, a pair of nostrils, and blood-colored teeth like a curved dragon spear tens of meters long, covered with black mouths, interlaced teeth, sharp as a fairy weapon.

According to the confessions of the powerhouses of the Demon Pavilion such as Peerless Heaven, Yutian and Splitting Heaven, Li Mu knew that the passage deep in the mouth of this skeleton was the passage to the legendary Thunder Prison.

Li Mu took a deep breath and entered it.

Passing past the skull's teeth and into the mouth, it was pitch black, like splashing ink, and the ground under his feet was uneven, and a tunnel led to the ground in the darkness.

Although there is no patrol by the powerhouses of the Demon Suppression Pavilion, the prohibitions and formations here are layer after layer, and if you follow the only correct route, you will not trigger the prohibition.

With such a humble position as Lu Manzi, he naturally didn't know the correct route.

But Li Mu was not afraid at all.

Under the guidance of several primordial gods in the [Green Soul Purgatory Lamp], Li Mu walked through this dark and long road little by little.

Then, I came to a crypt space.

This should already be more than 6,000 meters deep underground.

A world of magma and fire.

At the end of the corridor, there is an ocean of flames with no end in sight, the orange-yellow magma is undulating like the sea, a scorching heat rushes to the face, and the space seems to be slightly distorted, and there is a dense mist that is almost invisible to the naked eye, which is silently diffused.

The first hurdle.

Li Mu turned into a big fish, jumped directly into the magma, and sneaked forward.

He cultivated the path of fire.

In the midst of this flame, nature is like a fish in water, and there is no fear.

About 100 miles, Li Muyu jumped out.

Ahead was a yellow land with wind and sand.

The strange wind swept the grains of sand, which was enough to kill a strong man of the immortal king level in an instant.

And across this land, there is a real ocean, the blue liquid is surging, it is the weak water that Li Mu once encountered in the immortal mansion, even the martial arts emperor can be corroded, goose feathers do not float, everything sinks.

Li Mu turned into a blue bird and flapped his wings and flew.

Beyond the ocean, it is an endless metal world, with a strange metallic luster, and the metal mountains float, constantly colliding with each other, bursting out with dazzling sparks and brilliance.

Such an impact force is almost enough to instantly make an immortal monarch-level powerhouse die without a place to be buried.

Li Mu walked as fast as he could, constantly avoiding the impact of the metal mountains so as not to turn into sandwich biscuits.

"I met fire before, then earth, then water, and now gold, is it the five elements of gold, wood, water, fire, and earth?"

Li Mu guessed.

Sure enough, after crossing the metal world, you came to a strange forest world.

Leap by.

At the end of the forest world, there were countless huge vines, like a green snake tens of thousands of meters long, constantly spreading, constantly splitting out, and then it seemed that at the end of the whole world, an endless void appeared.

The vines fell downward, like a waterfall, towards the endless abyss below, and I don't know where it went.

"I once cultivated the Five Emperors Immortal Sutra, refining the power of the five organs, the power of dark alloy wood, water, fire and earth, the so-called five qi dynasty yuan, the heart hides the fire qi, the liver hides the wood qi, the lungs hide the gold qi, the kidneys hide the water qi, and the spleen hides the earth qi, the five elements world just now, could it be that it is the five organs of the human body's heart, liver, spleen, lungs, and kidneys?"

Li Mu secretly pondered in his heart.

But soon, his attention was focused on the void in front of him.

In the void space, pieces of star chips circulate.

Lilac thunder particles, looming among the stardust.

In the distance, large expanses of purple 'nebulae' spread across the void.

That's the legendary Thunder Hell.

The purple nebula is composed of endless world-destroying thunder, because the distance is too far, so it looks like a cloud, but in fact, when the distance is closer, you will know what a turbulent and infinitely destructive thundercloud it is.

According to the statement of the captured gods such as the Yutian Zhenren, the so-called Thunder Prison was not created by the Demon Suppression Pavilion, but existed congenitally, but it was discovered by the founding patriarch of the Demon Suppression Pavilion and transformed and utilized to create the current Thunder Prison.

The reason why Li Mu traveled all the way and didn't encounter any guards was because there were crises everywhere here, and even the strong people of the Demon Town Pavilion generally didn't dare to come here.

But if the formation that was secretly arranged was triggered, then countless top powerhouses of the Demon Town Pavilion would descend in an instant.

Li Mu is not afraid of fighting.

But I was worried that my energy would be involved, and countless people were successfully saved.

This is also the reason why we must wait until the ten thousand demons attack the mountain and the top powerhouse of the Demon Town Pavilion is led out before we can save people.

The founding patriarch of the Demon Suppression Pavilion has the talent to go through heaven and earth, he can transform this place into a prison that imprisons the top powerhouses of the Immortal Dao, and he can also use the power of the five elements of this world and the power of the thunder in the void to arrange a formation that even the Immortal Emperor will instantly obliterate.

You can never underestimate the heritage of a super-first-class immortal sect.

Whether it is from the confessions of Juetian and others, or Li Mu's own principles of doing things, it should be like this.

Li Mu observed carefully.

At this moment, suddenly, in the distance behind him, in that forest world, two extremely powerful energy fluctuations came from the direction, rushing towards the direction where Li Mu was.

Well?

Was it discovered?

Li Mu was shocked.

His figure sank, silently hidden behind the vines of the falling abyss.

In the next moment, two middle-aged Taoist priests wearing golden and jade Taoist robes came to the location where Li Mu had just been.

"It's so powerful. ”

Li Mu was secretly frightened.

From this angle, he couldn't see the faces of the two Taoist priests clearly, but the terrifying aura that inadvertently revealed on their bodies made Li Mudu feel a burst of heart palpitations and a chill on his back.

Not good.

This is a strong man above the two Immortal Monarchs.

Even...... Immortal Emperor?

In the Demon Suppression Pavilion, there are actually two emperor-level powerhouses?

Li Mu's scalp tingled.
