Li Mu had imagined that the demon cultivators caught and sent to the Demon Prison Mountain would be very miserable.
But when he saw it, he knew that the cruelty of reality was far crueler than he had imagined.
No, to be precise, the means and schemes of the Demon-suppressing Pavilion were far crueler than he had imagined.
In addition to being treated like slaves and squeezed dry, they were also used as cultivation materials to support the cultivation of the Taoist masters of the Demon-suppressing Pavilion. It was the first time that Li Mu had seen people using the Heaven's Fortune Creation Technique to cultivate and improve their cultivation on a large scale since he came to the immortal world.
The demon cultivators with special bloodlines and certain cultivation were tortured in the cruelest ways, making them release their greatest energy in great pain, fear, and anger, and then be absorbed by the Taoist masters. In the end, they were directly squeezed into dried corpses and piled up everywhere!
"What are you looking at? It's not your first time here. Be quick. "
Celestial Master Mu scolded.
Li Mu did not speak. He lowered his head and drove the Flying Ants deep into the prison area.
The deeper they went, the more gloomy, bloody, and horrible the scene was.
On the stone pillars and torture racks, dry bones were hanging, and there were demon cultivators who had died not long ago, just died, and not yet dead were nailed to them. Blood flowed down the stone pillars, leaving black mottled marks.
There were also some stone cages with barbs, where dried corpses were imprisoned. Their deaths were extremely miserable. The half-human corpses had the characteristics of beasts. Obviously, they had been tortured to death in the cruelest way. The pain they had suffered before death made their faces hideous like devils who were about to climb out of hell for revenge.
Bone mountains hundreds of meters high rose and fell continuously.
They were all piled up by the bones of demon cultivators.
The bones of different species and creatures were piled up, and the pale blue and dark purple ghostly fires were looming in the bones.
When the chilly wind whistled past, the bones made strange whistling sounds, as if countless angry and unwilling ghosts were growling and cursing at the same time.
Li Mu felt that his worldview had been turned upside down.
Although it was well-known that the Demon-suppressing Pavilion had been squeezing demon cultivators, Li Mu did not expect that it was so dark and cruel.
And this was only the periphery of the prison area.
After crossing the walls of bones, Li Mu followed Celestial Master Mu to the real area of heavy prisoners.
The densely packed fortresses were like ferocious beasts crouching on the scorched land, unmoving.
In every prison fortress, there were demonic cultivators who were constantly being tortured.
Following Celestial Master Mu's instructions, Li Mu sent the immortal herbs and elixirs to different prisons and fortresses. The miserable and terrifying scenes inside made Li Mu's scalp tingle.
He saw numerous Demonic cultivator experts being tied up and planted on the torture racks like trees. They were constantly being tortured to extract power, and their blood was being extracted and refined into Blood Pills.
In order to prevent them from dying, the jailers would constantly heal their wounds, inject energy, and use immortal medicines and divine herbs to prolong their lives.
This reminded Li Mu of the incident of extracting gallbladder from a live bear that had caused an uproar on Earth. Pharmaceutical companies fixed a live bear in a cage, inserted a rubber tube into the bear's gallbladder, and continuously extracted bile for medicine … After it was exposed, public opinion was in an uproar, and it was eventually banned.
And now, the Demon Subduing Pavilion's method was exactly the same.
Even more cruel.
This time, the medicine delivery trip was soon over.
After delivering all the elixirs and immortal herbs, Li Mu steered the Flying Ant Carriage to leave.
This was the first time he came to the prison area. Unfortunately, he did not get close to the rumored Thunder Penitentiary, which was not surprising. There were still two days before the demons attacked the mountain. Li Mu was not in a hurry to save people. Now, the most important thing was to figure out the terrain of the entire prison area, the tactical deployments, the number of patrollers, and the pattern. Then, it would be easier to take action.
After returning to the Herb Garden, Li Mu was undoubtedly ordered to do all kinds of chores again. He did not have time to catch his breath.
Until nightfall.
Li Mu only got six hours of rest.
He locked himself in the room to make others think that he was racing against time to cultivate. Then, he left a phantom doppelganger and left the Herb Garden for the prison area.
With Li Mu's current cultivation and means, he soon snuck into the depths of the prison.
After crossing the city walls made of white bones, Li Mu arrived in front of a huge skull.
The skull was thousands of meters high, roughly like a human skull, but there were three protrusions on its forehead, which looked like horns. The skull had one eye, a pair of nostrils, and blood-colored teeth that were dozens of meters long like curved dragon spears. The black mouth was full of crisscrossed teeth, which were as sharp as fairy weapons.
According to the confessions of the experts of the Demon Subduing Pavilion, Jue Tian, Yu Tian, and Lie Tian, Li Mu knew that the passage deep in the skull's mouth led to the legendary Thunder Penitentiary.
Li Mu took a deep breath and entered.
He passed through the teeth of the skull and entered the mouth. It was pitch-black like splashing ink. The ground under his feet was uneven. In the darkness, there was a passage leading to the underground.
Although there were no experts of the Demon Subduing Pavilion patrolling, there were layers of restrictions and tactical deployments here. Only by following the correct route would he not trigger the restriction.
Given Lu Manzi's humble status, he naturally did not know the correct route.
But Li Mu was not afraid at all.
Under the guidance of the several Primordial Spirits in the Green Soul Purgatory Lamp, Li Mu walked through the dark and long passage bit by bit.
Then, he came to a crypt space.
This should be more than six thousand meters underground.
It was a world of fire and magma.
At the end of the passage was a boundless sea of fire. The orange-yellow magma was surging like seawater. A gust of scorching heat hit him in the face. The space seemed to be slightly distorted, and there was a mist that was almost invisible to the naked eye spreading silently.
The first test.
Li Mu turned into a big fish and directly jumped into the magma, moving forward stealthily.
He cultivated the Way of Fire.
In this kind of fire, he was naturally like a fish in water, not afraid.
After about a hundred miles, Li Mu jumped out.
In front of him was a yellow land, swept by the wind and sand.
The strange wind swirled the sand, which was enough to kill an expert of the Immortal King Realm in an instant.
After crossing this land, they came to a vast ocean — a real ocean. The blue liquid was surging. It was the Weak Water that Li Mu once encountered in the Immortal Residence. It could even corrode the Great Emperor of martial arts. Even a goose feather would not float, and everything would sink.
Li Mu turned into a cyan bird and flapped his wings.
After crossing the vast ocean, it was a boundless metal world. Strange metal luster flickered, and floating metal mountains constantly collided with each other, bursting out dazzling sparks and brilliance.
Such a collision force was almost enough to kill an expert of the Immortal Realm in an instant.
Li Mu moved at high speed, constantly avoiding the collision of the metal mountains, lest he became a sandwich.
"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, he came to a strange forest world.
He flew over.
At the end of the forest world, there were countless huge vines. They were like giant green snakes that were tens of thousands of meters long, constantly spreading and splitting. Then, as if they had reached the end of the world, an endless void appeared.
The vines fell down like a waterfall, spreading to the endless abyss below. No one knew where they extended to.
"I once practiced the Five Emperors' Immortality Scriptures and refined the power of the five internal organs, dark alloys of wood, water, fire, and earth. As the saying goes, the heart contains fire qi, the liver contains wood qi, the lungs contain gold qi, the kidneys contain water qi, and the spleen contains earth qi. Does the world of the five elements just now correspond to the qi of the heart, liver, spleen, lung, and kidney?"
Li Mu thought to himself.
But soon, his attention was focused on the void in front of him.
In the void, pieces of stardust were swirling.
Light purple thunder particles were looming among the stardust.
In the distance, large tracts of purple "nebulae" covered the entire void.
That was the legendary Thunder Penitentiary.
The purple nebulae were formed by endless destructive thunder. Because they were too far away, they looked like clouds. But in fact, only when one got closer would he know how turbulent and destructive the thunderclouds were.
According to the Primordial Spirits of Immortal Yutian and the other captives, the so-called Thunder Penitentiary was not created by the Demon-suppressing Pavilion, but had existed since the beginning. It was only discovered by the founder of the Demon-suppressing Pavilion, who modified and used it to create the current Thunder Penitentiary.
The reason why Li Mu did not encounter any guards along the way was that this place was full of dangers. Even the experts of the Demon-suppressing Pavilion did not dare to come here.
But if he triggered the secretly set up tactical deployment, countless top experts of the Demon-suppressing Pavilion would arrive in an instant.
Li Mu was not afraid of fighting.
But he was worried that he would be distracted and could not save people successfully.
This was also why he had to wait until the demons attacked the mountain and the top experts of the Demon-suppressing Pavilion were lured out before he took action.
The founder of the Demon-suppressing Pavilion was a genius. He could transform this place into a prison to imprison top experts of the Immortal Path. He could also make use of the power of the five elements in this world and the power of thunder in the void to set up a tactical deployment that could kill even Immortal Emperors in an instant.
One should never underestimate the resources of a super sect in the Immortal World.
Whether it was from the confessions of Jue Tian and the others or Li Mu's own principles, it should be so.
Li Mu observed carefully.
Right at that moment, two extremely powerful energy fluctuations suddenly came from the forest world behind him. They were heading in Li Mu's direction at a high speed.
"Huh?"
"Have I been discovered?"
Li Mu was shocked.
He lowered his body and quietly hid behind the vines that fell into the abyss.
The next moment, two middle-aged Taoist priests in gold and jade robes came to the place where Li Mu was just a moment ago.
"What a strong power."
Li Mu was secretly shocked.
From his angle, he could not see the faces of the two Taoist priests clearly, but the terrifying aura that they inadvertently revealed made Li Mu's heart palpitate and a chill run down his spine.
Not good.
These two experts were above the Immortal Lord Realm.
Were they … Immortal Emperors?
There were actually two Former Emperors in the Demon-suppressing Pavilion?
Li Mu's scalp went numb.
