579: Tanggu Demon Prison! The breeding ground of the invisible demon race!

Poof!

The six Sword Sect Elders near Mysterious Feather instantly exploded into a muddy mess.

This scared Mysterious Feather, who quickly knelt and kowtowed: "Ancestor, spare my life! Black Demon truly did not know about this!"

"Hmph!"

The Formless Ghost Ancestor glanced at Mysterious Feather and became even angrier.

He raised his hand and slapped Mysterious Feather away: "Black Demon! Don't you dare forget! You are now the Sword Sect Master! As a sect leader, how can you be so lowly!"

"You are not these good-for-nothing pieces of trash! You are meant to bear great responsibilities! You must have backbone! You must have pride!"

He took this opportunity to reprimand Black Demon.

Afterward,

the Formless Ghost Ancestor said to Black Demon: "Don't investigate the matter of the Sword Tomb! I already know who the culprit is!"

"Who?"

Black Demon was stunned, asking in confusion.

His Mysterious Feather shell was already damaged, revealing the dense black energy within his chest.

The Formless Ghost Ancestor felt a little choked: "If you weren't my son, I would never have chosen you to be this Sect Master! Are you a pig-head?!"

"It's obvious, this is the work of that damned bastard Su Lie!"

Because he knew that only Su Lie, an Elder of Transmission of the sect who had cultivated the Peerless Sword Casket compatible with the Artifact Sword Path, could collect the countless sword energies within the Sword Tomb.

Since Su Lie had the qualification not to be harmed by the swords of the Sword Tomb,

then,

it must have been Su Lie, along with his accomplices, who used some unknown method to steal this Sword Tomb, which was filled with swords.

Otherwise,

the myriad swords on the mountain would be the first to object to this.

Back then,

he had also wanted to refine the Sword Tomb into his own treasure, but unexpectedly, he was interfered with by the multitude of swords on the mountain.

If he hadn't been greedy for these precious swords,

he would have taken forceful action long ago.

Thinking of this,

the Formless Ghost Ancestor's chest ached with anger: "Su Lie! I wish you a terrible death!"

There was nothing he could do.

He could only vent his impotent rage.

Now he truly had no power left to stop Su Lie... On the other side.

After Su Lie left the Sword Tomb space,

he immediately rushed to all the places where he worked without stopping.

After collecting all the resources from these warehouses one by one,

he also collected all 1020 profound heart grass, 1000 imperial dragon vine, and 12 blood fruit trees planted by Mysterious Feather.

Even the grain accumulated in the rootless rice Grotto-heaven was packed up.

He hadn't been idly working and learning management in various halls these past few days.

He was also studying the loopholes in various formations, trying to leave a back door for himself.

And he actually succeeded.

This time,

he obtained 1098 tons of rootless rice, 1001 sextillion tons of immortal fate rice, 192.8 billion tons of immortal spirit rice, and 1.29 million tons of immortal crystal rice.

100,000 Nine Heavens Sword Fruits, 10,000 Heavenly Origin Sword Fruits, plus 1000 trees each that bore these two types of fruits.

In addition, there were a total of 10.91 million various related items submitted from the Artifact Hall, Formation Hall, Pill Hall, and Talisman Hall to the main hall's warehouse.

After he completed this series of theft objectives,

Su Lie came to the Sword Pavilion again.

As he prepared to enter the Sword Pavilion,

a light flashed on the Sword Pavilion.

Su Lie actually manifested from his Invisibility Rule state.

This startled the two Sword Sect Elders on duty inside the Sword Pavilion.

"Su Lie!"

The two Elders stared with wide, round eyes and exclaimed.

Su Lie's heart sank at this sight; he felt a sense of death crisis through his Crisis Perception.

Before the crisis arrived,

Su Lie teleported to the back mountain, and then used the Invisibility Rule, re-entering an invisible state.

Boom!

At this moment, the spot where he had previously stood, which was the entrance of the Sword Pavilion, was blasted by a powerful force, creating a deep pit about 3 meters deep.

The Formless Ghost Ancestor arrived here aggressively, he raised his hand and pinched, and immediately a look of disappointment flashed in his eyes: "Damn it! He escaped again! That damned bastard! You'd better not let me catch you! Otherwise, I'll fry you alive!"

...On the other side.

After Su Lie left Heavenly Sword Peak, he headed straight towards the location of Tang Valley in Thousand-Hand Demoness's memory: "Phew! Everything that could be harvested has been harvested! Next, I just need to complete the mission and return to the Mist World!"

He had two missions from the mist rule.

He had already completed the mystery of the Ancient Sword Sect's downfall.

And although he already knew the location of the Ancient Sword Sect's bizarre birthplace,

since he hadn't personally set foot there,

he had not yet completed that mission.

Along the way, he passed Heavenly Sword Peak and arrived at the Sword Sect's inner disciple trial area.

This was a primitive jungle area with a diameter of 30,000 kilometers, inhabited by various fierce beasts and even beast kings.

Six military fortresses were built in its six directions.

Every now and then, this area would experience a beast tide.

At that time, all the inner and outer disciples would gather here to participate in the defense battles of the military fortresses, thereby obtaining fierce beast resources and a large number of points.

These threats seemingly originated from the expansionist desires of the fierce beast kings in this mountain range.

In reality,

the actual controller of this mountain range was the Sword Sect's Fierce Beast Peak.

Tang Valley was located in an underground valley in the deepest part of this primitive jungle.

The entrance at the top of the valley was a lake.

The color of the lake water was like millet soup, hence it was called Tang Valley.

When Su Lie passed through this area,

Su Lie found that the military fortress was under attack by a horde of fierce beasts.

Behind the beast horde, there were also beast kings holding the line.

Su Lie silently passed through the warring parties and quickly flew to the core area.

He quickly found Tang Valley.

"It really looks like millet soup!"

Su Lie flew in mid-air, looking at the rather conspicuous lake below him, and flew directly downwards.

Buzz!

Because he was in an invisible state, he did not stir up any ripples when he entered the lake water.

His entry into the water felt like passing through a layer of thin gauze.

[Buzz!]

[Exploration Hint: Dive approximately 10 meters, there is a hidden cave on the left stone wall. After entering, swim to the end to enter Tang Valley!]

[Exploration Hint: Tang Valley has now been transformed by the Formless Ghost Clan into their clan's birth base. The only supreme treasures here are the technical data from the biological modification laboratory and various precious materials.

Among them, the most valuable is a Time Deer.]

Upon seeing the Exploration Hint, Su Lie finally breathed a sigh of relief.

He quickly found the hidden cave and, after passing through a narrow passage, diving about one kilometer, and navigating a dozen intersection, he finally reached the exit.

When he emerged from the water,

outside was actually a heavily guarded military fortress.

The darkness was illuminated by the silver radiance moon on the dome.

Formless Ghosts, clad in heavy armor and wielding various sword-type weapons, patrolled everywhere.

Even at the water's edge by the entrance, there were several beast-like creatures on alert.

Moreover, the negative emotional pollution in Tang Valley was extremely severe.

Su Lie did not alarm them.

After passing through the fortress, he came to a spacious cavern behind it.

The cavern was vast, stretching for a full ten kilometers.

Various formations and restrictions were set up inside the cave.

Here, too, a larger silver radiance moon was embedded in the dome.

"Phew! A Legion of Formless Ghosts constantly in an invincible state! If I hadn't come in here, it would truly be unimaginable!"

Su Lie looked at the construction and situation here, realizing that the Formless Ghost Ancestor's ambition was certainly not as simple as just annihilating the Sword Sect and rebuilding a Shadowless Sect.

These Formless Ghosts already had the makings of a military formation, having developed a murderous aura.

Su Lie wandered freely in Tang Valley.

When he reached the end, he discovered a passage leading underground.

After descending a hundred meters,

Su Lie found another military training ground and barracks. According to his rough estimate,

there were nearly a million Formless Ghosts here.

And there were six more levels underground.

Each level was constantly expanding its space.

Except for the first level,

the lower levels had a diameter of at least 50 kilometers.

After Su Lie completed his exploration of this origin place of the Formless Ghost Clan,

he then returned to the first level.

On the edge of the stone wall here, there was another space.

This was the Sword Sect's laboratory.

It had now been transformed into the production and incubation base for the ghost clan.

The former prison cells had become breeding rooms.

The former laboratory benches had become operating tables for Formless Ghosts to undergo transplants.

Su Lie looked at these assembly-line-like modification rooms and realized that the production base in the well of the Great Abyss was probably a place meant to deceive.

"Who is the Formless Ghost Ancestor trying to deceive?"

Su Lie pondered softly.

He quickly found the laboratory's data archive guided by the Exploration Hint.

The archives here were all recorded in books in written form.

There were tens of millions of books in this data archive.

And the scientific researchers of the Formless Ghost Clan were constantly adding various data here.

Next to this data archive, Su Lie saw a research team specifically engaged in scientific research.

The head of the team was a Formless Ghost with a single horn on her head, and she was conducting a research project with the cooperation of her twelve subordinate Formless Ghosts.

"Is this a Time Deer?"

When Su Lie looked up, he saw the Time Deer in a state of spatial freezing within a strange space inside the laboratory wall.

This deer was covered in dense, tiny points of light.

It looked like it was constructed from light, but in reality, it was an animal with flesh and skin.

Su Lie felt a large amount of time energy on this deer's body.

Although this deer's internal organs had been removed and its limbs severed, it was still alive.

And under Su Lie's gaze,

the Time Deer's wounds were slowly healing.

Su Lie immediately performed Identification on the Time Deer.

[Buzz!]

[The Time Deer is an unknown time-based life form. Without the analysis of the rules, your current knowledge is insufficient to analyze this entity!]

"Huh? In an area not protected by the mist rule, I can't even use my Identification Talent! The main reason is still that my knowledge is insufficient!"

Thinking of this,

Su Lie looked again at the special space that was freezing the Time Deer outside.

It looked like a glass tank filled with transparent glue.

[Buzz!]

[Unknown Space Solidification Item: Red Rule Quality; can freeze all power and life, and keep the target fresh and capable, but without consciousness.]

"This thing can be taken away!"

Su Lie's eyes lit up.

He continued to walk deeper into the laboratory.

In the innermost layer, in an area protected by numerous formations,

he found a giant transparent gourd-shaped container.

A slender pipe connected the mouth of the gourd to a clear, transparent pool nearby.

The pool was very deep, and its internal space was vast.

This was not an ordinary pool, but a pool formed by condensed negative emotions.

It was currently transporting the water from the pool to various birthing rooms through over ten thousand pipes.

And in this pool, there was also a magic array composed of the silver radiance moon.

The massive amount of negative emotions required by the pool came from the transparent gourd that Su Lie had seen at first glance.

At the bottom of the gourd, there was a red lotus, and above the red lotus fire, countless souls were densely imprisoned.

In addition to this, it also contained various Vengeful Spirits and malevolent ghosts.

Su Lie looked at the scene before him, his scalp tingling: "How many lives must have been captured to hoard this gourd of souls, used as a constant source for generating negative emotions, continuously providing nourishment for the Formless Ghost Clan's reproduction!"

"No!"

"There's also the demand for absorption and cultivation!"

He also discovered a formation in an adjacent area.

Through his perception of this power, he found that

this formation was continuously evaporating and diffusing the water from the pool to various areas.

This was also the source of pollution for the entire Tang Valley.

Seeing no one here, Su Lie immediately submerged to the bottom of the pool.

He manipulated his Mysterious Yellow Energy, injecting it into this pool, thereby polluting the pool and transforming it into a source of Mysterious Yellow Energy pollution.

"Looks like I'll have to wait two days!"

Su Lie quickly emerged from the pool, and then walked into the laboratory to observe the experiments of the research personnel.

Just like that,

time passed little by little.

When the time came to the evening of the 23rd day,

just as Su Lie was about to act,

the Formless Ghost Ancestor suddenly arrived at the laboratory, causing Su Lie's expression to subtly tighten: "What is this old fellow doing here?"

...
