Chen Yun remained silent, but stretched out his hand and grabbed the empty space, and the wooden box quickly flew into his hand.

As he flicked his palm lightly, a green light flashed, the talismans on the wooden box fell off automatically, and the lid was easily opened.

A warm jade pendant containing the power of the five elements lies quietly in a wooden box. Although it looks plain, it exudes a rich spiritual energy.

Chen Yun picked it up and after a careful inspection, he suppressed his excitement and nodded to the female cultivator: "Yes, this is indeed a genuine product."

After saying this, he put the jade pendant back into the wooden box and turned his gaze to the several jade boxes nearby.

According to his original intention, he only wanted to exchange this piece of Five Elements Jade, but considering that the other party was a cultivator in the late Nascent Soul stage, he did not want to offend him easily.

In addition, seeing Kun Wuji being so generous, he also became interested in the items in these jade boxes.

Kun Wuji stretched out a finger and pointed at the jade boxes in the air with an expressionless face. The box lids automatically flew aside, revealing the various items inside.

"Falling Phoenix Wood, Soul Condensing Stone, Ten Thousand Wheels Flower..."

Before Chen Yun could recognize the things in the boxes, some monks sitting around him had already called out their names in surprise. Most people couldn't help but gasp.

The female cultivator at the side was also shocked after taking a look at these things.

The preciousness of these items is indeed extraordinary. Almost every one of them is as valuable as the Five Elements Jade. Especially the Ten Thousand Wheel Flower, its value is even not inferior to the Demon Marrow Diamond.

With such a rare treasure, no wonder Kun Wuji is so confident.

The female cultivator felt uneasy and couldn't help but turn her head to look at the blurry figure in the green light - Chen Yun.

She was stunned.

Chen Yun's gaze did not rest on the obviously most precious Wanlun Flower, but was staring at a piece of light golden ore in a jade box, thinking silently.

The woman's heart sank and she had a premonition of something.

Sure enough, as soon as Chen Yun raised his hand, the golden ore was sucked into his hand.

He lowered his head and looked carefully, his expression focused.

Kun Wuji was slightly stunned when he saw this scene, then he burst into laughter and said proudly:
"Why, fellow Daoist, you like this piece of Geng Jing of Kun? You really have a good eye."

"If you are a sword cultivator, this piece of Geng Jing is enough to greatly increase your magical power. And this large piece of Geng Jing, I am afraid that only Kun can take out such a large piece of Geng Jing in the entire Dajin cultivation world."

"I want this piece of Geng Jing." Chen Yun said lightly.

"Wait a minute, this Five Elements Jade..."

"Shut up, do you really want to irritate me?"

When Kun Wuji heard this, he was happy at first, but then his face suddenly changed. An astonishing aura suddenly emanated from his body, and an invisible spiritual pressure directly pressed down on the female cultivator.

Chen Yun stood aside unharmed, but the female cultivator was forced to take several steps back before she could barely stand.

Kun Wuji snatched the magic marrow diamond in front of Chen Yun and examined it with great joy.

"It is indeed the Demonic Marrow Diamond. I made the right decision to come here."

Kun Wuji put away the crystal diamond, laughed wildly towards the sky, then waved his sleeves and swept away the jade box on the table.

He flashed and flew quickly towards the exit of the hall.

"Brother Kun, there is one more valuable treasure that appears at the end. Don't you want to stay and take a look?"

The figure in the white mist who was hosting the exchange meeting spoke up to persuade him to stay.

"I don't care about any valuable treasures. Now that I have obtained the Demonic Marrow Diamond, I am anxious to go back and refine the essence of the demonic energy in it. How can I have the leisure to look at any valuable treasures?"

Kun Wuji laughed strangely, then triggered the restriction at the entrance and disappeared without a trace.

The Secret of Refining the Magic Diamond
When Chen Yun heard this, he was a little surprised, but he quickly understood the deeper meaning behind it.

This Demonic Marrow Diamond was condensed over many years in the depths of the Demonic Abyss. The pure demonic energy it contains is incomparable to any other ordinary item.

For a cultivator of the magic path, if he could successfully refine this substance, the benefits he would gain would undoubtedly be extremely significant.

Because of this, after obtaining this treasure, Kun Wuji lost all interest in the legendary treasure, which shows how precious it is.

At this moment, the female cultivator in the silver haze saw Kun Wuji leaving with the Demon Marrow Diamond, and she couldn't help but feel regretful.

She silently waved towards the wooden box containing the Five Elements Jade, intending to take it back.

However, at this critical moment, a calm voice suddenly sounded:

"Wait a minute! I also have a share of this."

Before he finished speaking, Chen Yun's palm had quietly appeared on the wooden box, easily preventing the female cultivator from taking it back.

In the silver haze, the female cultivator's voice suddenly turned icy cold.

The other monks were all shocked upon seeing this.

Chen Yun smiled slightly, held the wooden box with one hand, and quickly slapped the storage bag with the other hand, and another jade box flew towards the other party.

"I only want to exchange for the magic diamond. I'm sorry that I can't accept other items."

The female cultivator subconsciously took the jade box, but looked displeased.

"How about you take a look at the contents of the box before you say this?"

Chen Yun said with confidence.

The female cultivator opened a corner of the box with a little doubt, took a quick glance, and then let out an exclamation of surprise.

"Okay! The Five Elements Jade is yours."

The female cultivator smiled happily, immediately closed the lid, put the jade box away, and turned away as if nothing had happened.

The monks around were all confused. They did not see the contents of Chen Yun's third jade box and were very puzzled as to why the female monk suddenly agreed to exchange it for the Five Elements Jade.

In the world of immortal cultivation, people had different opinions about what Chen Yun showed, and some even speculated whether he had taken out the third magic marrow diamond.

After all, it is already shocking for one person to take out two, and if he adds another one, it would be simply horrifying.

However, most people did not believe this, and thought that what Chen Yun took out might just be other precious treasures to impress the female monk in front of him.

Despite all the different opinions, Chen Yun ignored these strange looks. His eyes were fixed on the figure of the female cultivator that was looming in the silver haze, and his brows unconsciously frowned slightly.

He didn't notice it at first, but when he looked at it carefully, the woman's blurry back gave him an inexplicable sense of familiarity.

Could it be her?

This sudden idea surprised Chen Yun himself.

Although judging from the voices, there was no similarity between the two, but for cultivators like them, changing voices was just a piece of cake. With his thoughts racing, Chen Yun couldn't help but use the Mingqing Spirit Eyes technique to try to see through the truth in the silver haze.

Although he couldn't completely penetrate the light curtain, he could at least see the other person's figure more clearly than before.

Upon seeing this, a strange expression appeared on Chen Yun's face.

Although her identity still cannot be confirmed, this woman's appearance is extremely similar to Saint Tianlan.

During a mysterious treasure exchange event, a mysterious woman returned to her seat with Chen Yun's third magic diamond without realizing his true identity.

Chen Yun felt complicated. It was undoubtedly a mockery that the materials he had searched for with great difficulty were obtained from his old enemy.

Although his heart was filled with strange feelings, Chen Yun quickly put away the Five Elements Jade and Geng Essence and walked towards his seat.

For him, the source of the material is not important; what matters is that the goal has been achieved.

He also unexpectedly obtained a large amount of Geng Jing, which greatly simplified his future refining tasks.

These Geng essences are enough to complete the production of most of the sword formation. He only needs to collect some more Geng essence to refine thirty-six Green Bamboo Bee Cloud Swords again, which makes Chen Yun feel very satisfied.

In the subsequent exchange, although there were thirty or forty cultivators participating, because high-level materials such as Demon Marrow Diamond and Five Elements Jade had already appeared, everyone seemed absent-minded and most of them just did it in a perfunctory manner.

Only a few succeed in exchanging for treasures.

Although some extraordinary treasures were subsequently displayed, these items could no longer arouse the interest of other monks.

Finally, when one monk returned to his seat, no one came forward to participate in the exchange.

Seeing this, the figure in the white robe who originally hosted the exchange meeting calmly walked behind the jade table again.

"Since all of you fellow Taoists have completed your exchanges, we will now begin auctioning the last treasure of this exchange, which is also the most valuable treasure of this trade fair."

After saying this calmly, the man suddenly clapped his hands, making two light "pa pa" sounds.

Then, a flash of light appeared at the entrance of the hall, and two male cultivators walked in.

Surprisingly, the two monks did not have any talismans on their bodies. They revealed their true faces and walked towards the center.

There was a sudden commotion among the monks present. Most of the monks present could call out the names of these two people. They were the old man with a black hat and the middle-aged man with a square face who had appeared in a mansion in the imperial city.

Among these two people, one is at the early stage of Nascent Soul Realm, and the other is at the middle stage. Both are Nascent Soul-level elders of the royal Ye family who often deal with outsiders.

Most of the monks were puzzled by the treasures at the exchange meeting, and only a few knew what was going on.

They had received the news in advance and had specially attended the exchange meeting just for this treasure, so they were very excited at the moment.

At this time, the old man in the black cap walked to the table, nodded to the figure in the silver haze, turned to the monks and said slowly:

"I'm sure that most of you here know us. This treasure is a treasure that the Ye family spent countless manpower and resources and spent hundreds of years to refine."

"However, recently several sects have been seeking to purchase this item at the same time, and it is inconvenient for us to offend or reject any of them."

"After discussion at the Council of Elders, we decided to hold the final auction at this exchange meeting to see which Taoist friend is lucky enough to obtain it."

As soon as the square-faced middle-aged man finished speaking, he winked at the old man in the black hat.

The old man in the black hat took out a square box about a foot long from his sleeve, looked at it reluctantly for the last time, then gritted his teeth and handed it to the person in the silver mist.

In the midst of the white mist, a figure appeared leisurely.

He chuckled slightly, and without further ado, decided to directly show the true appearance of the treasure.

With a slight shake of the jade box in his hand, the lid of the box instantly flew into the sky, and then a ball of dazzling yellow light slowly rose from the box.

This ball of yellow light seemed to have spirituality, sometimes expanding and sometimes contracting, while making a low humming sound, like the chanting of an ancient spell.

At the same time, another figure in the silver haze had a solemn expression on his face. He quickly made hand gestures and shot out a series of spells like meteors.

Finally, he pointed at the ball of yellow light and let out a low roar, as if he was casting some profound spell.

After a few wild flashes of light, the ball of light suddenly began to spin, and then the light converged, revealing a strange object - a small khaki seal.

This small seal is square and its surface is as smooth as jade, but a faint flickering golden and silver miniature magic array can be seen on its surface.

Each flash reveals a different rune, making it feel mysterious.

What is even more astonishing is that although the spiritual energy emanating from this small seal is peaceful and stable, the power contained in it is extremely huge, causing all those who feel it to change their expressions and feel awe.

In the vast world of immortal cultivation, there exists a treasure called Pingshan Seal.

This treasure was refined by imitating the ancient magical treasure "Seal of Heaven".

The cultivators of the Ye family had personally tested it. According to them, although this treasure only possessed one-tenth or one-twelfth of the power of the rumored Heaven-controlling Seal, its ability to split mountains and crack the earth was absolutely a problem.

What is even more amazing is that if a cultivator has a high level of cultivation, he can unleash the power of this treasure beyond normal levels, and it is possible to achieve one-third of the power of the Heaven-Paying Seal.

However, it should be noted that such use will greatly damage the treasure and should not be attempted lightly.

A figure slowly emerged from the white mist, explaining the magic of the Pingshan Seal while skillfully manipulating the Pingshan Seal in front of him.

Under his control, the Pingshan Seal kept changing in size, with a yellow hazy light flashing in between.

An astonishing power that was ready to be unleashed quietly spread out, causing all the monks in the hall to be excited.

Even without this demonstration, the words "replica of Tongtian Lingbao" alone are enough to demonstrate the extraordinary value of this treasure.

Regardless of whether they knew the situation of this treasure in advance, the many monks present had their eyes fixed on this small seal, unwilling to move their eyes away even a little.

When Chen Yun heard the words "imitation of Tongtian Lingbao", he was stunned.

In order to collect the materials to refine the Three-Flame Fan, he had gone through untold hardships, but he has not yet collected all the necessary materials.

Unexpectedly, a counterfeit Tongtian Lingbao appeared at this exchange meeting. This unexpected situation made Chen Yun feel depressed.

Chen Yun’s knowledge of the Tongtian Lingbao was limited, especially the legendary “Heavenly Seal”, about which he knew nothing.

He pondered in his heart, if his Three-Flame Fan was successfully refined, compared with this mysterious treasure, which one would be stronger?

Lord Dayan seemed to have seen through Chen Yun's doubts and explained at the right time:
"Don't worry too much. The power of the Pingshan Seal is only one-tenth or one-half of the original magic weapon at best."

"And the Three Flame Fan that I have researched can reach 40% of the Seven Flame Fan's maximum power. Even under certain conditions, it is not impossible for it to perform beyond normal capabilities."

"Although both are offensive magic weapons, in terms of power, the Pingshan Seal is probably still inferior to your Three Flame Fan."

Upon hearing this, Chen Yun nodded secretly, and his thoughts coincided with what Dayan said.

He longed to complete the refining of the Three Flame Fan as soon as possible. Once he had this treasure in his hands, he would be able to deal with cultivators in the late Nascent Soul stage. (End of this chapter)
