In an instant, a hot breath spread, and a sea of ​​fire quickly formed, turning all the poisonous insects on the ground into ashes.

"Tsk tsk! Fellow Daoist Chen's control over magic has reached perfection. If you were to say that Fellow Daoist Chen's main skill is fire-attributed, I'm afraid no one would disbelieve it."

A woman's light laughter came. Chen Yun responded calmly:
"Nothing. In my early years when I was at a low level, I used the Fire Bomb Technique the most. It's just that practice makes perfect."

Then, in the silver light in the distance, the figures of the big man, Chen Yun and others gradually appeared, and walked towards the gradually extinguished sea of ​​fire. Chen Yun glanced around and suddenly stopped.

He noticed that the poisonous fog on the other side of the sea of ​​fire was unusually thin, and there was something vaguely visible.

However, just as he was about to release his spiritual sense to investigate, the leading man suddenly pointed at the jade ruyi above his head, and the treasure immediately emitted a burst of silver light and flew forward.

Under the silver light, the originally foggy scene became clear.

Chen Yun looked carefully and found a huge ravine appeared dozens of feet ahead.

He looked to both sides and saw that the length of the ravine was difficult to estimate, but its width was as wide as a hundred feet.

A light black wind would occasionally gust out of the ditch, blowing the surrounding poisonous fog into pieces.

"This is the entrance to the Yin Yang Cave. Let's go over there."

An old man said.

Except for Chen Yun and Bai Yaoyi, everyone else seemed to be very familiar with this place, so they walked towards the giant ditch without hesitation.

Although the cold wind blowing out of the ditch was extremely fierce, these people remained calm and looked down without panic.

The depth of the giant trench is unfathomable, like an endless abyss.

Balls of dark wind formed whirlpools of varying sizes in the ditch, and from these whirlpools came bursts of ghostly howling sounds.

Chen Yun's eyes swept across the ditch walls on both sides, only to see that they were covered with sparkling ice.

The current environment seems calm, but it is actually fraught with crisis.

Once you go hundreds of feet underground, you will be attacked by terrifying cold winds.

Even a cultivator at the Nascent Soul stage would find it difficult to withstand this wind for too long if he is caught off guard.

However, with the power of the Purple Phantom Pearl, the threat of this wind to us is greatly reduced.

The intensity of the terrifying cold wind in different areas of the Yin-Yang Cave varies. My fellow Taoists are all experienced practitioners, so there is no need for me to say much about how to act here.

After he finished speaking, the old man surnamed Fu slowly raised his hand, and suddenly a fist-sized purple round bead appeared in his hand. It was the Purple Youzhu.

When the pearl appeared, Chen Yun's attention was instantly attracted. He stared at the purple pearl and instantly felt a purple shadow flashing in his eyes. His consciousness involuntarily fell into a trance, as if his soul was about to leave his body.

This sudden change startled Chen Yun, but at this critical moment, the Dayan Jue in his body suddenly started to work automatically. A cool feeling quickly spread through his mind, restoring his mind to normal.

Chen Yun remained calm on the surface, but was shocked inside.

He thought to himself that this Purple Phantom Pearl was indeed the Demon Sect's treasure, and its power was indeed extraordinary and extremely evil.

Thinking of this, Chen Yun couldn't help but cast inquiring glances at the big man surnamed Yuan and Bai Yaoyi.

In this tense situation, the two men's eyes flickered and their faces looked quite ugly.

Apparently, they were also caught off guard and suffered the loss of the bead.

However, it remains unknown what kind of mysterious magic these two people used to escape from the bewitching effect of the beads.

The old man surnamed Fu seemed not to notice the three people's visit. He just held the bead steadily in one hand and recited an obscure spell.

In an instant, a dazzling light flashed, and a faint halo slowly emanated from the bead.

The halo instantly enveloped an area of ​​more than thirty feet in radius, and Chen Yun and the other four were also enveloped in a light purple halo.

At this moment, the originally fierce icy wind around suddenly weakened and its power was greatly reduced.

"The Purple Nether Pearl is indeed worthy of its reputation!"

After the big man surnamed Yuan put away the jade ruyi in his hand, he couldn't help but let out an exclamation of admiration.

"It is still difficult to judge the true power of this bead. We have to wait and see what happens next."

As the old man surnamed Fu spoke, he still held the Purple Pearl in one hand and released a ball of purple-red light mist with the other hand, looking calm and composed.

After saying this, the old man's body was flashing with green light and he slowly floated down the ditch.

Chen Yun and others naturally would not easily leave the protective range of the purple halo. They released their protective treasures and flew into the deep ditch closely behind.

During a fierce battle, the big man sacrificed a emerald green jade token, which floated above his head.

Bai Yaoyi used ice crystal flying knives to circle around her body.

The beautiful woman in black held a black shield close to her body for protection.

Chen Yun spewed out several golden flying swords to protect his entire body.

Soon, the figures of several people were swallowed by the dark vortex below after a flash of spiritual light, and disappeared without a trace. The area near the giant ditch returned to peace again.

At the same time, above an unnamed small lake in southern Xinjiang, seven or eight monks were suspended in the air, listening to the speech of a monk in black.

Among these cultivators there were both secular people and monastics. They were several of the Ye family cultivators who had gathered in the imperial palace a few months ago.

The big-headed monster stood in the middle of the crowd, his body swaying, and next to him was a square-faced monk in the middle Nascent Soul stage.

Not far away, a young ancient demon who looked very similar to Chen Yun listened quietly with no expression on his face.

Although the black-robed monk in the story is only at the Jindan stage, he is extremely respectful when facing the clan elders who are at the Yuanying stage.

Four hundred years ago, the Ye family learned about the possible location of the "Kunwu" sacred mountain through the broken stele in the ancient ruins and began to plan for exploration.

This holy land of immortals was sunk into the ground by ancient cultivators using their magical powers for unknown reasons. Its rich ancient caves and two legendary magical treasures are extremely valuable.

If the Ye family obtains these two treasures, their strength will be greatly enhanced, enough to intimidate the major sects of both the righteous and evil sects.

After more than a hundred years of hard work, the Ye family finally found the place recorded in the stone tablet at the bottom of Dajin Lake, and sent a formation master to break the ban.

This matter was personally handled by the previous great elder, and few people knew about it.

The black-robed monk paused for a moment and continued:
In ancient times, the immortal world laid down numerous restrictions. The depth of these restrictions was far beyond the imagination of ordinary people. They were layered one upon another, almost covering the underground world within a radius of 100 miles.

In order to break these restrictions, more than a dozen formation masters spent hundreds of years and finally found a way to break the formation with another formation.

This process not only requires the help of the power of heaven and earth, but also requires a large number of materials and an extremely complex magic array, making it an extremely arduous project.

What was even more difficult was that many of the materials needed to set up the formation were rare treasures that had to be carefully collected, and the entire process of setting up the formation had to be done in secret, without attracting the attention of those with ulterior motives. Otherwise, all the efforts might be used to benefit others. Therefore, the arrangement of the forbidden-breaking formation was intermittent, and was even forced to be suspended many times.

Only recently has the project come to a close.

Currently, the formation master of the clan is setting up the last formation at the bottom of the lake, and it is estimated that it will take about a month to complete.

At that time, we will activate a super-stealth formation to suppress the strange phenomena produced when the ban is broken, so that the elders can calmly enter Kunwu Mountain to obtain the treasure.

After the explanation, the black-robed monk stepped aside and said no more.

"So our destination is Kunwu Mountain?"

Everyone originally thought that this was the cave of an ancient monk, but some people pointed out that only a fairy mountain like Kunwu Mountain could have such a magical treasure.

For a moment, except for the weirdo, the square-faced monk and the ancient demon, the rest of the monks were whispering to each other with excitement on their faces.

"Humph! Don't be too happy too soon."

The square-faced monk said with a gloomy expression:

"Breaking the restriction is only the first step to obtaining the treasure. If obtaining the treasure is really that simple, why would Third Brother gather us here and ask Seventh Uncle for help?"

"And as the great elder, Third Brother will arrive in a month to avoid the eyes and ears of other sects and enter Kunwu Mountain with us."

"From what my second brother said, is there anything wrong in Kunwu Mountain?" The elder of the Ye family couldn't help but ask.

"It's not just inappropriate. This time we go in, we may never come back." The square-faced monk said gloomily.

"How is that possible? We have two great monks in our seventh uncle and third brother. Even if there are powerful restrictions, it shouldn't be a problem, right?" a Confucian scholar asked in amazement.

Among the quiet mountains, Kunwu Mountain stands tall with its graceful appearance. It is a holy place that cultivators dream of.

However, this mountain was sealed due to some unknown secrets, and a magical treasure was left behind as a clue or warning.

Faced with such a mystery, even experienced practitioners dare not act rashly.

The square-faced monk frowned, and a hint of worry appeared in his tone:
"If only everything could be that simple. Think about it, why would our ancestors choose to seal up such a spiritual place?"

"What kind of shocking thing is hidden behind this? The hidden dangers are probably far beyond our imagination."

These words made everyone present change color. They looked at each other in silence, secretly speculating in their hearts.

Seeing this, an old man who was called a weirdo smiled lightly, trying to ease the tense atmosphere:

"Don't worry too much. Maybe there is a reason behind this. Of course, it's always right to be cautious. If you really encounter any trouble, I will help you."

After hearing this, everyone's expressions relaxed a little.

At this moment, the square-faced middle-aged man suddenly turned to the man named Elder Chen behind him, and his expression became serious:
"Brother Chen, considering your profound knowledge of ancient literature, we will need to rely on your wisdom during this exploration of Kunwu Mountain."

"Please rest assured. We have found two vital magic weapons. After this matter is completed, we will return them to you intact."

This conversation not only shows their cautious yet determined attitude towards unknown challenges, but also implies that a journey full of unknowns and dangers is about to begin.

The ancient demon replied calmly: "Since the magic weapon is the reward, I should do my best."

After saying this, he nodded casually. The square-faced monk heard this and smiled with satisfaction:

"It is enough for a fellow Taoist to say this."

He looked around and his tone turned serious.

"Although this place is remote, we still need to be cautious to avoid any complications. Everyone, follow me to the bottom of the lake."

Before he finished speaking, aura flashed all over his body and he dived down to the lake first.

Seeing this, the others also moved and followed closely.

In an instant, ripples appeared on the surface of the lake, and the figures of the monks disappeared in the blue waves, leaving only a breeze blowing across the lake, quiet and silent.

However, at the bottom of the Yin-Yang Cave thousands of miles away, Chen Yun and his companions encountered an unexpected incident.

Chen Yun's mind moved slightly, and golden light burst out in front of him, instantly smashing a one-horned ghost that was rushing towards him.

At the same time, golden light flashed again above his head and under his feet, and two more ghosts were split in half by his sword, and the ghost bodies turned into black mist and dissipated.

At this time, he turned around to look at his companions, and saw that the old man surnamed Fu and others also used magic weapons to wipe out all the remaining ghosts. Although these ghosts were not big, they were extremely ferocious and fearless.

In a dim underground cave, Chen Yun looked solemn with a slightly furrowed brow.

He and his companions have been deep in this mysterious cave for several days, but have not found any trace of Yin Zhima.

Thick black fog filled the air, and the chilling atmosphere made people shudder.

The big man surnamed Yuan pointed forward, and a beam of green fire pierced through a little ghost. Then he said in a deep voice:

"Brother Fu, we have been traveling for many days, but we have not seen any trace of Yin Zhima. Although these low-level ghosts have no intelligence, there are many of them. If we just kill them blindly, it may not be a long-term solution."

The old man surnamed Fu heard this, but he was not in a hurry, and responded confidently:
"Brother Yuan, don't worry. This cave is vast and boundless. Yin Zhima is good at hiding. How can he be found easily?"

"Although there are many ghosts, it is easy for us to kill them. As long as we use spirit stones to replenish our mana, we can hold on for a long time."

Bai Yaoyi looked around and sighed softly:

"That being said, it will take a lot of mana to resist this terrifying wind. With our cultivation in the middle stage of the Nascent Soul, I'm afraid we can only stay here for about two months."

They were now in a tall passage, with crystal black ice gleaming on the earth walls on both sides.

The black wind, which was even thicker than that at the entrance, swirled around them, making bursts of shrill screams that made people feel uneasy.

However, when the dark wind invaded the halo emitted by the old man's orb, most of it was quickly dissolved. Although Chen Yun and others were surrounded by spiritual light, they still did not dare to let the remaining black wind touch their bodies.

At the same time, little ghosts continued to emerge from the black wind all around them, attacking them like moths to a flame.

Bai Yaoyi's flying knife flashed, turning a little ghost into an ice sculpture and shattering it, finally clearing the ghosts around. Several people then took back their magic weapons and continued to move forward along the passage.

Inside the Yin-Yang Cave, there were gusts of cold wind, making it difficult for spiritual consciousness to probe far. People did not dare to control their escape lights to travel quickly, otherwise it would only take a few days to explore all the passages.

After just a moment, the black wind ahead suddenly intensified, and a three-way intersection appeared in the wind, with three passages, one large and two small, appearing in front of them.

Chen Yun and others stopped and said with cold eyes:

"Another intersection. If we continue like this, we may not be able to find all the caves in two months. We must act separately." (End of this chapter)
