Chapter 81: Could the Dirty Stone Black Rain be...

Zhang Wei looked at this place suspiciously.

A deep cave with a thick and foul smell.

"That's it?"

Ning Caichen explained: "Ever since the disaster of the dirty stone black rain more than 5,000 years ago destroyed the Yunya Immortal Sect, most of the area has been burned to ashes by the flames transformed from the dirty stone black rain, turning into a white land.

Therefore, if you want to find the ruins of the Yunya Immortal Sect, you just need to focus on digging at the places where the dirty rocks and black rain gather.

This is a place where dirty stones gather that I once discovered. At the time, I also thought about searching inside to see if I could find some opportunities.

In the end, he only found some magic weapon fragments, and his body was contaminated by the foul air emitted by the dirty stone inside. Later, he soaked in the spiritual spring for a long time before recovering. "

Speaking of this, Ning Caichen also sighed. He didn't expect that the dangerous place that he had avoided at the beginning has now come back again!
And this time I have no choice but to go in!
"Dirty stones... black rain..."

Zhang Wei touched his chin and muttered.

Zhang Wei had heard countless times about these two culprits that caused the decline of the Five Realms Immortal Path, but he had never actually seen them.

Even in the "Records of Miscellaneous Matters of the Five Realms", there is no detailed description of these two items.

As for the source of the foul air, the cultivators were also eager to avoid it, so after the disaster, the remaining filthy stones and black rain were collectively dealt with by the cultivators. Some of the filthy stones were thrown into the sea, and the other part was buried deep together with the black rain using earth magic.

Only places like Black Mountain, where a fire broke out and burned the area to ashes, have survived. However, after five thousand years, the remaining dirty stones have been buried by sand.

Unless it is a casual cultivator who wants the legacy of the Yunya Immortal Sect, no one is willing to dig up such things.

Otherwise, your whole body will be contaminated by turbid air, which will greatly affect your spiritual path.

Even Zhang Wei was on high alert at this moment. He stood at the entrance of the cave and did not go in immediately. Instead, he put his hand on the wall at the entrance.

then……

Buzz~~

The electromagnetic force spreads rapidly inward along the walls of the cave.

This is the method of using the power of consciousness that Zhang Wei has cultivated over the years. He uses his unique electromagnetic force to sense the structure of objects he comes into contact with, and then forms a three-dimensional view of the perceived structure of the object in his soul.

This is Zhang Wei's preparation for entering various dangerous places in the future. As long as he practices well, Zhang Wei will be able to have a God's perspective in various dangerous places, which will be very convenient for searching for treasures or escaping from danger.

In addition, Zhang Wei also discovered that the more powerful the existence, the stronger the magnetic field it emits, and each person's magnetic field is different.

Therefore, Zhang Wei can completely use this trick to see through other people's disguises and make everything hidden under his electromagnetic divine consciousness.

Of course, if the other party’s breath-concealing technique is too advanced, or if he has the ability to completely transform himself into another being, Zhang Wei will have no way of detecting the truth.

At least he can't now.

Under Zhang Wei's electromagnetic perception, the direction of the underground cave and even the number of stones on the road were presented in Zhang Wei's mind in great detail.

Not only that, Zhang Wei also found hundreds of rats inside!

This is good news. The presence of creatures like rats means it is still relatively safe inside.

But there is also bad news, because each of these rats is as big as a mastiff, and the largest one is as big as a calf!

Zhang Wei asked Ning Caichen, "Do you know if there are monsters here?"

"Monster?"

Ning Caichen was stunned. Seeing Zhang Wei's gloomy eyes, he quickly explained: "Please forgive me, senior. The last time I came here was forty years ago. I really don't know the environment inside!"

Seeing Ning Caichen's frightened expression, Zhang Wei determined through the induction of the electromagnetic magic sand that the other party's heartbeat was just rapid due to fright, and he put aside some of his doubts about Ning Caichen.

He waved his hand and said, "You'll encounter some strange rats on the road, remember to clean them up."

Hearing Zhang Wei's words, dozens of demon cultivators including Ning Caichen all looked bitter, but they did not dare to disobey Zhang Wei's wishes, so they could only walk into the cave.

Not long after, the rats in the cave discovered the intruders. With a series of rapid calls, a dozen red-eyed rat monsters, whose cultivation level was probably in the early stage of Qi Refining, rushed out and attacked the group of demon cultivators without fear of death!

However, the weakest demon cultivators present were all in the middle stage of Qi Refining, so they were naturally not afraid of these rats and easily dealt with them.

But one demon cultivator was still injured. Looking at the festering wound and the red-eyed rat demon on the ground, he couldn't help but say, "This is a vicious beast!"

A vicious beast?

Zhang Wei raised his eyebrows, and records about ferocious beasts emerged in his mind.

The so-called ferocious beasts, like spiritual beasts, are different names for monsters.

But its personality is at the opposite end of that of a spiritual beast. It has an extremely strong desire to kill and is extremely ferocious. It is very difficult to communicate with it effectively, so it is called a ferocious beast.

In the current five domains, the name for ferocious beasts is those monsters that have absorbed too much foul air, thus affecting their mind.

The flesh and blood of this monster is heavily contaminated with foul air, so its value would be cut in half if it were sold, so few monster hunters are willing to take the initiative to deal with this kind of thing.

Ning Caichen looked at these red-eyed rat monsters and said, "It seems that there is too much foul air in the cave, which has turned these rats into vicious ones."

Everyone looked at Zhang Wei again, and he nodded calmly and said, "Keep going, there are still a hundred or so ahead, and the largest one is as big as a calf."

Upon hearing Zhang Wei's words, everyone present except Ning Caichen turned pale.

Hundreds of vicious rats, and a rat king as big as a calf? !
Everyone quickly turned to look at Ning Caichen, her eyes seemed to be saying.

Boss, you go to the front row!

Ning Caichen's face darkened, but he did not refuse, because he knew that in Zhang Wei's eyes, his foundation building was the same as other Qi-refining magic cultivators.

They are all used to deal with mines.

In this way, the crowd advanced and killed along the way.

With a Foundation Establishment cultivator fighting in the front row, all the rat monsters in the cave were quickly killed. Only the Rat King wasted some time, but he did not last two moves from Ning Caichen and was beheaded directly.

Zhang Wei came to a black stone wall, reached out his hand and touched the black stone wall, his frown growing deeper and deeper.

"This is... the dirty stone?"

Ning Caichen opened his mouth and said, "Yes... Sir, you don't know?"

Zhang Wei told the truth: "I just came from another place, and this is the first time I have seen the appearance of the dirty stone. So this is the dirty stone..."

Zhang Wei's speech was calm, but actually his heart was already in turmoil!

If... he was not mistaken, this so-called dirty stone had another familiar name in his previous life.

coal.

Yes, it looked like coal and felt like coal! It was exactly the same fuel he used to heat his home in the winter in his previous life!
Is coal dirty stone?

What is the foul gas produced after combustion?
Things like carbon dioxide, carbon monoxide, sulfur dioxide, nitrogen dioxide, nitrogen tetroxide, nitric oxide, and dust?

Zhang Wei had so many complaints in his mind that he wanted to complain.

But he still knocked off two pieces of coal and turned away, while ordering: "Dig."

"what?"

The monks were stunned, and then looked at Zhang Wei's back with disbelief.

"Senior...Senior...this is an unclean stone!"

Some people wanted to beg for mercy, but Zhang Wei's conscience would not give them mercy.

He turned around, looked at the man and said, "Why, you don't want to do it? That's fine."

Hearing Zhang Wei's words, the monks' faces lit up with joy.

But at this moment, Zhang Wei stretched out his hand and made a pistol gesture to the person who spoke first.

puff!

Countless blood holes appeared all over the demon cultivator's body, and the divine light in his eyes dimmed at the same time. Hundreds of black sand also drilled out of his body, turning into a small iron bead and flew back into Zhang Wei's sleeve.

"Just die."

With a thud, the body fell to the ground and the cave suddenly became quiet. The only sound in the air was the clear sound of Zhang Wei's footsteps as he left.

Ding-ding-ding-ding-ding...

Sitting outside the cave, listening to the knocking sounds coming from inside the cave, Zhang Wei weighed the coal stone in his hand and recalled the limited records about the dirty stone in his mind.

According to legend, when the dirty stone burns, it not only produces foul air, but also releases evil sounds that disturb people's souls.

If a cultivator practices near a burning filthy stone, not only will he easily absorb foul air into his body, but he will also hear devilish sounds, causing low-level cultivators to go astray and fall into madness. Only the divine consciousness of Master Zifu can resist and suppress it.

"Turbid air... Devil's voice..."

Zhang Wei muttered, and casually took out a second-level exorcism talisman that he had bought from Linglong Fairy Island, and with his other hand, he released a fire spell at the dirty stone under his feet. The dirty stone burned instantly, and wisps of black smoke began to appear in the air, and a smell that Zhang Wei was very familiar with came out.

At this moment he was finally sure.

Dirty stone is coal!

At worst, it's just a fuel like coal!

However, just when Zhang Wei thought that the so-called devilish sound piercing his ears was just an illusion caused by the monks inhaling too much toxic gas produced when coal was burning, a whisper suddenly sounded in his ears!
Zhang Wei was very sure that he did not breathe in any poisonous gas, because the turbid gas was covered by his magic weapon as soon as it was produced.

But the so-called devilish sound still appeared in his ears.

This shows that this dirty stone is not just simple coal.

The content of the whispers was very strange. Zhang Wei could understand each word clearly, but when they were connected together, Zhang Wei could not understand them anymore.

"Damn... Has the world of immortal cultivation offended some Cthulhu god? How come even the Whisper of the Ancient Gods has come out?" Zhang Wei couldn't help but curse inwardly.

But he didn't go crazy because of the whisper.

After all, his cultivation is now not weak, and he is also blessed with the power of divine consciousness. The demonic sound produced by a small piece of dirty stone has no effect on Zhang Wei.

Moreover, as the filthy stone burned, Zhang Wei compared it with the coal in his memory and found that this so-called filthy stone burned longer and had greater firepower, even better than those high-quality spiritual charcoal!

If we remove the foul air and the devilish sound it produces, it is definitely a high-quality fuel!

Zhang Wei simply used this magical sound as background music and started to read the relevant knowledge about coal in the book in his mind again.

After a quick browse, Zhang Wei fell into deep thought.

Coal is formed from ancient plants through a series of complex geological processes under high pressure and high temperature, but it should be buried underground. How could it fall from the sky and turn into the so-called disaster of filthy stone?

And the Black Rain...

"and many more……"

Suddenly, a flash of lightning flashed through Zhang Wei's mind, causing him to make associations.

What if the filth stone is really like coal, and before it turned into filth stone, it was a part of the body of some creature or creatures? And it was a part of some incredibly powerful existence?
Their bodies and flesh have been permeated with large amounts of high-quality spiritual energy during their long period of cultivation, so that every bit of it contains pure energy.

And the foul air produced after burning... the devilish sound...

Zhang Wei thought, according to legend, when a cultivator reaches the Nascent Soul stage, his soul will undergo another transformation. Will he become the original spirit from the fairy tale novels in his previous life?
The power of the primordial spirit is omnipresent, and even after the death of a great monk, some of it may still remain. So it is not impossible that it can transform into the so-called devilish sound on the fragments of its body.

What about the black rain?

Could it be blood?

The blood of that great monk? !
So what kind of disaster could destroy such an existence, turning its flesh and bones into filthy stone, and its blood into black rain that covers the five realms?

Zhang Wei thought of a disaster that they had to face!
"Heavenly disaster!"

Perhaps five or six thousand years ago, there was a powerful being, or even many powerful beings who were trying to overcome the calamity in the five realms together, but they ended up dying.

Under the influence of the power of the heavenly calamity, their bodies turned into the so-called filthy stones, and their blood turned into black rain, falling into the five realms, affecting the five realms for thousands of years!

The remaining power of their souls entangled with the fragments of the corpses, and was released as the burning continued. Then, they followed their instincts and let out unwilling cries? Or was it a narration?

The more Zhang Wei thought about it, the more likely it seemed. He didn't know if it was an illusion. As Zhang Wei's thoughts became more and more profound, he seemed to understand the content of these magic sounds better in a trance.

“Vast…”

"Xianmen..."

"Become an immortal..."

"Dongzhou..."

After hearing the word Dongzhou, Zhang Wei suddenly woke up. At that moment, he seemed to see an incredibly huge blue dragon roaring to the sky!
Countless purple thunders exploded between heaven and earth, and then it was as if a pair of giant eyes opened in the sky, and an extremely thick purple thunder struck down, chopping the giant green dragon down from the sky!

hold head high------

Lightning flashed in Zhang Wei's eyes instantly, and electromagnetic divine thoughts surged out, shattering all the illusions before his eyes. Then, without thinking, he slapped himself and stuck the exorcism talisman on his head!
Zhang Wei breathed a sigh of relief when he felt a cool sensation. Only then did he realize that his back was soaked with cold sweat!
"How is that possible? Even if a cultivator cannot survive the heavenly tribulation, his body should have been shattered to pieces by the heavenly tribulation, right?

How could it turn into this so-called dirty stone?

But just now, I seemed to see something?
Am I also affected by this evil sound?"

Just when Zhang Wei was confused, he found that the filthy stone was still burning and the foul air was still being produced, but the incomprehensible devilish sound had disappeared.

"Magic sound..."

Zhang Wei lit another piece of dirty stone, and the familiar whispering voice came again, but this time, the voice could not cause Zhang Wei to be moved in the slightest.

Zhang Wei blinked, and the electromagnetic power was released. There seemed to be a tremor in the void, and then the devilish sound seemed to have met its nemesis. Under the influence of the electromagnetic force, it was torn into countless pieces and disappeared.

Zhang Wei was surprised and asked, "Can my electromagnetic divine thoughts destroy these evil sounds?"

It is worthy of being one of the four fundamental forces of the universe, it’s so awesome!
"If that's the case, then this dirty stone will be useful to me!"

Zhang Wei looked back at the dirty stone cave where hammering sounds were still coming from, and murmured, "Maybe, I can be a coal boss!"

Coal, as an important fossil energy in the development of human industry in Zhang Wei's previous life, plays a vital role in many aspects.

Although it is not known whether this filthy stone can be developed into as many uses as coal, just based on the fact that it has a higher combustion efficiency than many of the coals Zhang Wei had in his previous life, it is also very good to use it to generate electricity.

Ever since Zhang Wei broke through the foundation-building stage 20 years ago and was able to absorb spiritual energy on his own to practice, Zhang Wei gave up the research and development of the hydroelectric generator.

Apart from helping those Zhang family members whose spiritual roots had not yet awakened to conduct experiments, Zhang Wei seldom used the method of absorbing electricity to practice.

There was no other reason. The speed of absorbing electricity was almost the same as when he used his spiritual veins to practice. With his current level of cultivation, it was difficult for the electricity provided by those primitive generators to help him.

He needed some stronger source of electricity.

But there is no suitable place in Canglong Mountain or even in the entire Yun Kingdom. He can't use spiritual charcoal to generate electricity to power himself, right?
That would cost too much.

Zhang Wei often set up a formation to call the wind and rain, and then took the opportunity to practice with the power of thunder. However, the power of thunder drawn in this way was also very dangerous. The amount of electricity and voltage of each lightning were different, and it was far less stable and safe than thermal power generation.

Unexpectedly, this dirty stone was found in the Black Mountain Range!

According to Ning Caichen, although most of the dirty stones were burned more than 5,000 years ago, there are still more than 300 places where dirty stones are accumulated that have not been affected in the thousands of miles of Black Mountains.

If every place where the filthy rocks accumulate is the same as the cave in front of us, then the reserves will be at least at the level of 10 billion tons!
That’s enough for Zhang Weishi!

Of course, the prerequisite is that Zhang Wei lights up the technology tree of thermal power generation and develops a series of machines such as turbines.

Zhang Wei touched his thick hair and couldn't help but sigh: "The road to immortality is indeed a never-ending journey..."

"It seems that I still need to study mechanics in depth. Hmm... and mining... No, it seems that this dirty stone cannot be mined and burned casually."

Zhang Wei suddenly remembered that due to the influence of the dirty stone and black rain disaster more than 5,000 years ago, the cultivators of the five regions hated these two things.

It would be fine if Zhang Wei just mined the dirty stones, but if he dared to openly burn the dirty stones and release foul air, he would be cutting himself off from the human race in the Five Realms, and even the demon cultivators would have to come and cause trouble for him!
Therefore, unless Zhang Wei can conquer all five regions, he can only do things like mining dirty stones and even thermal power generation in secret.

It seems that I can only be the boss of an illegal coal mine?

Zhang Wei felt so depressed.

However, at this moment, he suddenly discovered that the outermost layer of the dirty stone that burned first turned into fragments and fell to the ground.

The residue is not white as the legend says, but has a light green color.

Zhang Wei was stunned, then quickly put out the fire and picked up a handful of light green powder.

"This is……"

Zhang Wei felt it carefully, and then found that this small handful of powder actually contained a wisp of pure wood spirit energy!
The wood spiritual energy is the wood-attributed spiritual energy among the five spiritual energies. It is a special kind of spiritual energy that can usually only condense in wood-attributed spiritual veins. It can greatly promote the growth of spiritual plants.

But burning the dirty stone can bring out the wood spirit energy?

Are you kidding me?
"Could it be..."

Zhang Wei covered his eyes, took out another piece of dirty stone and lit it. He let the evil sound linger in his ears without any movement, just waiting for it to burn slowly.

When the surface of this piece of dirty stone shattered, the powder that appeared was no longer the one containing the wood spirit energy, but was the ordinary gray-white powder recorded in the classics.

Zhang Wei murmured, "Sure enough, it is the devil sound... These devil sounds are emitted with the help of the wood spirit energy.

After I used electromagnetic divine thoughts to break the devil's sound, the wood spirit energy was no longer consumed, but continued to remain in these byproducts after the filthy stone burned. "

Zhang Wei couldn't help but sigh, "It really is worthy of being called the world of immortal cultivation. There are such magical minerals. Since there is wood spirit energy, then this filthy stone is not only useful for generating electricity. At least we can make a lot of money by using the powder as fertilizer."

Then Zhang Wei looked into the cave, listening to the knocking sounds inside, and suddenly felt that the sounds inside were so beautiful.

But when he thought about the fact that he only had dozens of demon cultivators working for him, he felt as if his heart was being cut by a knife!
Zhang Wei touched his chin and muttered, "It seems... I have to find some companions for you."
