In the mysterious cave, everyone started a discussion around the Purple Pearl.

There is only one Purple Ghost Pearl, and it plays a crucial role in resisting the magical power of the Shocking Yin Wind.

Once the protection of this bead is lost, the consumption of mana will be doubled, and the time everyone can stay in the cave will be greatly shortened.

The big man surnamed Yuan looked at the purple pearl in the hand of the old man surnamed Fu, shook his head slightly, and showed a worried look on his face.

The old man surnamed Fu said that if he could make use of the power of the Purple Youzhu, he could consume his essence and blood to temporarily bless everyone with the divine light of the pearl.

However, this method of blessing has a time limit. Even if the size of the terrifying Yin wind remains constant, the divine light of each blessing can only last for about seven or eight days.

After thinking about it, Chen Yun believed that seven or eight days should be enough time for everyone to explore the branching channel.

But the prerequisite is that before the purple divine light is exhausted, it is necessary to ensure that the old man surnamed Fu can be found in time to bless it again.

To do this, they need to leave magical marks on each other. Only in this way can they find each other through secret techniques.

Bai Yaoyi raised a new concern. What should she do if she unfortunately encounters a high-level ghost that is difficult for one person to deal with?
In that mysterious and deep cave, the man named Yuan, as a cultivator from southern Xinjiang, was well aware of many secrets of this place.

He hummed slightly and said slowly:

"Humph! If even we cultivators who have reached the middle stage of the Nascent Soul cannot deal with this ghost, then it must be at least a ghost king level existence."

"But this place is not the real underworld. How could such a ghost be born with just this pervasive yin energy?"

"I think there are only a few evil spirits deep in this cave."

"As for the Ghost King who is said to be as powerful as a great cultivator, it is nothing more than a rumor made up by the world. Who has actually seen his true appearance with their own eyes?"

"This risk is worth taking."

"After all, once our magic power is exhausted, when the wind subsides and the flood season ends, it will be even more difficult for us to enter this place again."

Upon hearing this, the old man surnamed Fu and the beautiful woman in black could not help but look at each other, with a hint of hesitation on their faces.

In order to ensure that the operation was foolproof, they never considered acting separately.

However, the Yin-Yang Cave is vast underground, with intricate passages and caves, and its scale far exceeds their initial expectations.

If we don't act separately, we will most likely return empty-handed.

After Bai Yaoyi thought about it for a while, she seemed convinced and no longer raised any objections.

At this time, the old man surnamed Fu finally made up his mind and said in a deep voice:
"Okay, let's do as you say."

“But you must be careful and do not leave me for more than three days. Otherwise, if you encounter danger, you may not have enough time to ask me for divine protection.”

In the deep underground cave, everyone started to explore the main passage.

Chen Yun looked at the clearly defined passage at the middle intersection and said calmly:

"Don't worry, everyone. There must be a main passage in this underground cave. Those branch passages must not be too long. With our strength, three days is enough to explore this place thoroughly."

Hearing Chen Yun's words, the old man no longer hesitated. He decisively opened his mouth and spurted out a ball of blood, which fell on the purple pearl.

In an instant, the pearl shone brightly, and the dazzling light illuminated the surroundings.

The old man quickly formed seals with his hands, chanted several spells in succession, and then reached out with one hand to grab the orb in the air.

I saw a ball of dazzling purple light slowly emerging from the bead and slowly flying into the old man's hands.

The old man held up the purple light steadily with one hand, and after looking at the other four people in turn, he shot the purple light in his hand towards the beautiful woman in black beside him.

The purple light flashed by and instantly penetrated into the beautiful woman's body and disappeared.

Immediately afterwards, a layer of soft purple light emerged from the beautiful woman, enveloping her entire body. This purple light was exactly the same as the halo emitted by the Purple Phantom Pearl.

Seeing that this secret technique really worked, the big man and others felt relieved, so they decided to follow this method and have the old man surnamed Fu use the same method on other people.

When everything was ready, after several people planted magic marks on each other, they divided into three groups and headed towards three passages respectively.

The old man surnamed Fu and his junior sister were the first to step into the thickest passage in the middle.

The big man and Chen Yun entered the passages on both sides respectively, and a mysterious cave exploration journey began.

After a brief hesitation, Bai Yaoyi decided to follow Chen Yun into the same passage.

Chen Yun sensed that the woman in palace dress was following closely behind him. After a slight hesitation, he slowed down and waited for her to approach. The two walked side by side.

"Fellow Daoist Chen, don't you think the Yin-Yang Cave is a bit misnamed? It is said that once a cultivator enters this cave, he will be separated into Yin and Yang, and it is full of dangers."

"However, since we entered the cave, we haven't encountered any major difficulties, except for the frightening cold wind."

"Is the name of this Jedi just an empty reputation?" Bai Yaoyi followed Chen Yun's steps and suddenly asked this question.

Chen Yun was slightly surprised when he heard this, but then responded with a smile:

"Although I know a little bit about this place, the name of the Seven Great Jedi of Dajin is not groundless."

“Fellow Daoist Bai, please remember that the terrifying Yin wind was so powerful that even cultivators below the Nascent Soul stage, even if they had their own life-definition magic weapon to protect them, could not escape the fate of being torn apart by the Yin wind vortex at the entrance.”

"It is precisely because of the protection of the Purple Nether Pearl's divine light and our cultivation that far exceeds that of ordinary cultivators that we have been able to remain safe and sound until now."

"Besides, we have only been underground for a few days, and we have only encountered low-level ghosts. If we continue to go deeper, the yin energy will be more dense, and we will surely encounter more powerful ghosts."

In the dim and gloomy wind, Bai Yaoyi and Chen Yun were talking when they suddenly noticed seven or eight ghosts approaching quietly.

These ghosts pounced on them viciously, but were quickly killed by the two men with cold golden light and disappeared without a trace.

The two decided to travel together temporarily and search slowly forward.

However, after most of the day's efforts, they still found nothing.

When they came out of the cave empty-handed again, a sharp and piercing scream was heard, full of brutality.

"What is this?" Bai Yaoyi was stunned.

"It sounds like the sound of refining a corpse." Chen Yun said lightly, his eyes flashed, as if he had understood something.

"Refining corpses? Such a coincidence!" The woman in palace clothes raised her eyebrows, a little surprised.

The two men followed the sound without fear, and after turning a corner, a cave several meters high suddenly appeared on one side of the passage.

The black wind inside was howling non-stop, and it was far more violent than the dark wind in the passage.

And the sound of ghost howling was faintly heard from this cave.

"Hey! What is this?"

Bai Yaoyi caught a glimpse of something stuck next to the entrance of the cave, but its entire body had been frozen in ice and was shining brightly.

Bai Yaoyi raised her hand slightly, and several hot fireballs suddenly shot out and hit the target accurately.

In an instant, with a loud bang, the red flames quickly melted the ice, revealing the object hidden inside.

It was a blue flying sword, the blade of which was deeply embedded in the wall, with only a small half sticking out.

However, at the moment when the ice melted, the lifeless flying sword suddenly flashed with a faint spiritual light and emitted a crisp sound. Then, the hilt began to tremble violently, like a nimble snake trying to break free from the ice wall.

Bai Yaoyi showed a look of surprise and shook her sleeves lightly. A red rope shot out like lightning and tightly wrapped around the hilt of the sword in a flash of red light.

With a light wave, she pulled the flying sword out of the ice wall and held it steadily in her jade hand.

Bai Yaoyi's eyes flickered, and she gently waved the sword in her hand. A sword light several feet long appeared out of thin air and fiercely slashed on the ice wall. Seeing this, Chen Yun's expression changed slightly.

"This flying sword has been around for many years, and it still retains its spirituality. It can be seen that its owner put a lot of thought into it."

"Judging from the power, the owner of the flying sword should be a cultivator in the middle or late Jindan stage. However, cultivators of this level usually cannot reach this place, which is really strange."

Bai Yaoyi looked through the sword several times but did not find any useful markings, and a look of confusion appeared on her face.

"How about letting Chen take a look too?" Chen Yun suddenly asked.

"You're too polite, fellow Daoist. Please do as you wish." Bai Yaoyi smiled and flicked the flying sword towards him.

Chen Yun stretched out his hand and took the flying sword into his palm, then lowered his head to examine it carefully. After a moment, his brows slightly frowned.

"What's the matter, Brother Chen, have you figured out anything?" Bai Yaoyi asked curiously.

This flying sword is made of blue crystal as the main material, but this material alone is not the best choice. If other auxiliary materials can be added, the quality of the flying sword will be improved.

However, this single-material refining method was once popular more than 10,000 years ago, while the technique of refining multiple materials mixedly was only developed later.

Judging from the patterns and runes on the flying sword, it is obviously very old.

This shows that although its owner is not an ancient cultivator, he should still be a cultivator from tens of thousands of years ago.

Chen Yun analyzed calmly. Bai Yaoyi was surprised at Chen Yun's attainments in weapon refining:

"Brother Chen's weapon refining skills are so advanced, I am really surprised!"

"Nothing, I just happened to see this kind of flying sword in the atlas."

Chen Yun responded calmly.

He suggested entering the cave to explore, perhaps they could find more.

After a brief thought, Bai Yaoyi nodded in agreement, released a misty white jade umbrella, and walked lightly towards the cave.

Chen Yun smiled slightly, commanded the flying swords above his head to transform into a golden light to protect his whole body, and then calmly followed them into the cave.

In the deep and dark cave, only the sound of the wind and the faint screams coming from afar broke the silence.

The ghost in the cave seemed to have sensed the arrival of someone and became more violent.

However, these voices have not gone away.

Chen Yun whispered to himself: "This place is limited in scale, so we should be able to handle it."

As soon as he finished speaking, he waved his hand, and a moonstone emitting white light floated above their heads. Then he cast a spell to activate it.

The moonstone then emitted a dazzling light, illuminating everything around it.

Even so, the dark wind still blocked the view, and things a little further away were still blurry and difficult to distinguish.

The two walked along the cave passage for only fifty or sixty feet when the view in front of them suddenly opened up and they saw an entrance not far ahead, with a light green glow shining through it.

Chen Yun and Bai Yaoyi looked at each other in surprise.

All the caves they had explored before were extremely cold and dark, with no light at all.

Moreover, those mines have long been abandoned and are worthless.

Chen Yun and Bai Yaoyi have high cultivation levels, and although they are wary, they do not shrink back.

Bai Yaoyi held a jade umbrella to shield her body and took the lead to step into the entrance.

She looked inside and suddenly turned pale.

Chen Yun appeared beside the woman, glanced at her, and his expression changed slightly.

In front of us is a stalactite cave with a diameter of more than thirty meters.

The ceiling and walls of the cave radiate a faint green light, and in the center of the cave stands a stone pillar several meters high.

This stone pillar looks rough and simple, inconspicuous, but there is a dried corpse tied to it with iron chains, which is very strange.

The mummy had long, gray hair, its body was naked and pitch black, its head was lowered, its face was difficult to discern, and its abdomen seemed to have been cut open with a sharp knife, with all its internal organs gone.

Even Chen Yun couldn't help but feel frightened by such a strange situation, and Bai Yaoyi looked even more terrified.

When Chen Yun pursed his lips and was about to speak, the blue flying sword in his hand suddenly made a long sound, and then began to tremble wildly.

Chen Yun's mind moved, and he threw the flying sword into the air without thinking.

Suddenly, a blue light pointed straight at the stone pillar, and when it got closer, it turned into a half-foot small sword, circling around the mummy, making bursts of wailing sounds.

"Could this mummy be the owner of the flying sword?"

Bai Yaoyi sighed softly, a trace of pity showing on her face, "Looking at his appearance, not only was his golden elixir taken away, but even his life was not saved."

In the mysterious cave, a secret and strange sorcery sacrifice is quietly unveiling its mystery.

Chen Yun's eyes were stern and his tone was calm, yet it revealed an unquestionable certainty.

Reveal the truth behind the extraordinary death - this person did not die in the ordinary sense, but was killed by an evil method of living sacrifice.

Bai Yaoyi was shocked when she heard this, and then she turned her attention to the ground of the cave.

There is a fuzzy magic circle over ten feet in size. The dust of time has almost buried it. If you don't pay attention to it now, it will probably be overlooked.

Chen Yun nodded slightly and analyzed calmly:
"We can only know what kind of living sacrifice formation it is by recreating it."

Bai Yaoyi raised the corners of her mouth slightly, revealing a confident smile, and said in a soft voice:

"This is not difficult. I can accomplish it myself."

After saying this, she opened her red lips and spit out a small fan that was as crystal clear as an ice sculpture.

In a flash of cold light, the small fan instantly turned into the size of a foot, and then gently waved towards the ground of the cave.

In an instant, a yellow gust of wind blew out from the fan like an angry dragon galloping, instantly blowing the sand on the ground into the sky.

The sight of flying sand and rocks made the entire cave plunge into darkness, and it was pitch dark.

Chen Yun and Bai Yaoyi were both blessed with the purple divine light and protected by spiritual light, so they seemed to be unaware of the raging sandstorm.

The two of them fixed their eyes on the magic circle on the ground, as if everything around them had nothing to do with them. They only wanted to find out the secrets hidden behind the magic circle.

In this tense atmosphere, suddenly, a faint light flickered on the ground about ten feet behind them.

Then, a dark thing quietly emerged from the ground and lay there motionless, as if it was watching everything from the dark, adding a bit of weirdness to this mysterious scene. (End of this chapter)
