Naturally, not everyone could successfully complete the transaction. Some monks were unable to achieve the purpose of trade because the items they provided were too obscure or of good quality but extremely scarce.

However, these Yuanying-stage predecessors are all wise men who have insight into the world, and it is almost impossible for them to try to gain benefits through exchanges of unequal value.

The Fire Dragon Boy and Lu Luo both conducted transactions before Chen Yun and each showed the items they exchanged.

The Fire Dragon Boy took out a tricolor flower about the size of a bowl, which was a raw material needed for alchemy. Although its value was not as high as the original red essence, it was still a rare item.

However, he hoped to exchange for a material called "Poison Talisman Wood", but unfortunately no one present had it.

The Fire Dragon Boy could only return to his seat with disappointment.

In comparison, Lu Luo's deal was quite successful. He exchanged a bottle of spiritual herb juice that Chen Yun had never heard of for a fiery red flying sword that had not yet recognized its owner. As for who the sword was prepared for, it was unknown.

Given his age, he probably no longer has the time to spend a lot of time cultivating this sword.

After Lu Luo finished the transaction, it was Chen Yun's turn.

Because Chen Yun successfully snatched the red essence ganoderma from the brocade-robed monk not long ago, he attracted a lot of attention.

Chen Yun stood up calmly, holding two pale white jade boxes in his hands.

"I have one level six water and one level six fire demon pill, as well as two Thousand Spirit Grasses. I am only willing to exchange them for information about the Heaven and Earth Divine Thunder."

As soon as Chen Yun finished speaking, he shook his hands lightly, and with a flash of green light, the lids of the two jade boxes were opened at the same time.

Two red and blue demon pills and two emerald green spiritual herbs appeared in everyone's consciousness.

"Heaven and Earth Divine Thunder?"

As soon as Chen Yun's words came out, the monks around him showed surprise.

These magic pills and thousand-year-old spiritual herbs are extremely precious items, but they are only exchanged for information about the divine thunder.

As we all know, there is a huge gap between information and actual access.

Although many natural treasures and ancient monastic sites are widely known, they are located in either dangerous places with few people or in remote places full of dangers. Even monks with great magical powers find it difficult to obtain them.

The most famous case is the Demon Valley located in the central part of Tiannan Continent.

It is said that this place is an ancient battlefield. It is said that in the wild times, many ancient great magical cultivators set up strange formations and prohibitions here, and fought each other for some unknown reason.

In the end, due to the amazing power of the divine power, countless tiny cracks appeared in the space, making the space of the entire valley extremely unstable.

In the end, all the ancient monks who participated in the battle died together, the space was in chaos, and the existence of ancient array restrictions made this ancient monk battlefield full of deadly dangers. The Demon Valley thus became a dangerous place that made people shudder.

Over the years, countless high-level cultivators who boast of their extraordinary magical powers and spiritual attainments have ventured into the abyss to hunt for the ancient relics and techniques contained therein, but so far no one has managed to survive.

Therefore, more than a thousand high-ranking monks died here one after another, and the various rare treasures they carried with them were also scattered in the valley.

Over the past thousands of years, no one has dared to challenge the Fallen Demon Valley, which has firmly established itself as one of the most terrifying and dangerous areas in the Tiannan Continent.

However, although practitioners throughout the Tiannan Continent knew that the Dark Demon Valley had rich treasure resources, they could only watch from afar and could not touch them, and no one was willing to take the risk of falling into this dangerous situation.

Now it seems that this extremely mysterious divine thunder is obviously not something that ordinary cultivators know about.

Therefore, all the monks present turned their eyes to Chen Yun, but no one dared to communicate through voice transmission. Faced with such a situation, Chen Yun felt a little lost in his heart.

He knew very well that if he couldn't offer more valuable treasures, it would be almost impossible to expect to get what he needed in just one trade fair.

Therefore, he deliberately took out these relatively low-value demon pills and spiritual herbs as exchange items.

However, he was quite frustrated that there were so many Nascent Soul cultivators gathered in front of him, but they knew nothing about the relevant information.

He sighed softly, looked aimlessly at the monks around him, his brows slightly wrinkled, and an expression of surprise appeared on his face.

However, he did not hesitate for a moment and sat down in his seat.

Immediately afterwards, a cultivator below quickly took out a piece of pitch-black refining material and began to explain its properties in detail.

Chen Yun did not listen attentively to the monk's explanation. Instead, he closed his eyes and fell into deep thought.

Just now, he seemed to be correct. When his eyes swept across Master Tianjing, although the other party's face was as calm as water, the hint of hesitation in his eyes was keenly captured by him.

From this we can see that even if Master Tianjing does not have the divine thunder in his hands, he must have important information about the divine thunder.

Chen Yun did not spend too much time speculating, as he had already made a clear judgment in his mind.

However, he was also a calm and composed person, and he did not rush to ask through voice message, but chose to pretend he knew nothing and quietly wait for the best opportunity.

Another half an hour passed, and it was finally the turn of the last cultivator to complete the exchange of what he needed. At this time, Tianjing Zhenren walked to the center of the venue again and said with a smile:

"It seems that most of you have successfully exchanged for what you need. Friends who failed to get what they wanted do not need to worry. Currently, the Yuanying stage Daoists who came to Tiantian City only account for about one-tenth of the total number. There are still countless opportunities waiting for you in the future. Let's not talk about others for now. At least I will hold a larger-scale trade fair again, and I look forward to your visit again. Before that, I also have a few items I want to exchange with you."

As soon as he finished speaking, the old Taoist's hands flashed with light, and in an instant he took out seven or eight different items from his storage bag and piled them on the table in front of him.

After seeing the items on the table clearly, the other monks were all shocked and looked astonished.

After carefully observing these items, Chen Yun raised his eyebrows slightly.

It turned out that there were seven or eight puppet monsters of various shapes placed on the table, including a white giant wolf, a green python, and even one that looked like a red bull.

Although these puppets seemed lifeless, they emitted terrifying spiritual power fluctuations, far exceeding those puppets hidden in Chen Yun's storage bag. Their strength might have reached the early stage of Jindan.

However, they were not the types described in the puppetry scripture that Chen Yun practiced. Driven by the sudden thoughts that emerged in Chen Yun's mind, he couldn't help but once again look at the puppets in front of him intently.

However, just when he was about to find any abnormality from this puppet, the fat man from the Hehuan Sect across from him spoke with a smile.

"Oh! Fellow Daoist Tianjing, I'm sorry that I didn't notice that you were actually studying puppetry. Could it be that you intend to abandon the 'Crystal Light Skill' that you have been studying before? If that's the case, I, Old Ju, really have to express my admiration from the bottom of my heart!"

"Brother Ju, you are too polite. I am already old, so how can I easily try a new way of cultivation? These puppets were actually obtained by me and a few fellow Taoists during a recent expedition to an ancient ruins."

"I am penniless right now, so I have no choice but to exchange this item for what I need. Although it is not very powerful for us, it still has a unique effect in certain specific environments."

Master Tianjing responded with a smile.

"I see. I am quite interested in these puppets. They are perfect for protecting the safety of my disciples. But I wonder what you would like to exchange for them, Master Tianjing?"

Another monk who looked older said this while stroking his long beard.

"Haha, what I want is quite rare. It is something called 'Soul Stone' in ancient times. One Soul Stone can be exchanged for one of my puppet beasts. These puppets were all made by ancient monks. I am afraid there are no such high-level puppets in the world anymore."

Master Tianjing explained in a calm tone.

"Soul stone?"

Upon hearing this unheard-of name, the monks present all looked confused.

They had never heard of this kind of thing before; it was too unfamiliar.

Seeing this, Master Tianjing seemed to have anticipated this. He reached into his arms and took out a thumb-sized emerald green crystal.

At first glance, this crystal stone looked like a wood-attributed spiritual stone. However, when everyone's spiritual sense swept it, they found that the crystal stone did not emit the wood-attributed spiritual energy that the cultivators were familiar with, but instead an extremely cold and mysterious fluctuation.

"Perhaps some of you here have this item, but you may not recognize it. I happen to have one here, and you can identify it first."

The old man held the crystal in his hand and continued slowly:

"Well, it is indeed somewhat strange. It seems to have the power of the ghost, but it is far purer than the power of the ghost."

A demon monk whose whole body was shrouded in black aura asked in surprise.

"I don't know what exactly is contained in this crystal stone. But I can be sure that it is definitely not ordinary soul energy. Otherwise, why would I be willing to exchange these puppets for such a stone?"

Master Tianjing answered honestly.

"Oh I got it."

The demon monk wisely stopped asking questions.

Looking at the so-called soul stone, a faint smile appeared on Chen Yun's face.

This is exactly the Yinming Beast Crystal that he obtained in the Yinming Land, and it is also the core of these ancient puppetry techniques.

This soul stone was apparently little known to many people. After a while of waiting, only one cultivator hesitantly took out a piece, then stepped forward and exchanged it for a beast puppet.

After asking several times, Master Tianjing saw that no one came forward. Although he had already foreseen this situation, he still couldn't help feeling a little lost deep in his heart.

Just as he was about to take back the remaining puppet beasts, another person suddenly stood up and walked towards him. This cheered up the old Taoist, and he looked at the newcomer expectantly.

"My fellow Taoist, do you also possess a soul stone?"

When Chen Yun silently turned his palm, a piece of emerald green crystal appeared in his hand. However, the size of this crystal was comparable to that of an egg, and the cold aura emanating from it could almost be detected by the naked eye, far exceeding the crystal shown by the old man.

Tianjing Zhenren was shocked at first, and then immediately fell into extreme joy, but a bright smile appeared on his face and he said respectfully:
"My dear fellow Taoist, the soul stone you hold is so huge and extremely rare. Well, for example, since you like it, you can choose two from those puppets and take them away. I promise that I will never let you suffer any loss."

"Just two?" After hearing this, Chen Yun smiled faintly and shook his head.

"Don't you think it's too little? I wonder what kind of exchange terms you are going to propose?" Taoist Master Tianjing was not angry at this, but asked calmly.

"How about using this soul stone to exchange for all of your remaining puppets?" Chen Yun asked in a calm tone.

"In exchange for six puppets! Do you think this is too greedy, fellow Daoist?" When Taoist Tian Jing heard this proposal, he was shocked as if he had suffered a heavy blow. He frowned and said with full of complaints.

"Haha! Whether it is greedy or not, the real person should have his own conclusion in his heart. The value of this soul stone cannot be measured by its size alone. Moreover, for the real person, such a huge soul stone is undoubtedly of extremely high value..."

Chen Yun stared at Master Tianjing and suddenly paused before he finished speaking.

When Master Tianjing heard this, his expression changed slightly. He looked at Chen Yun deeply for a while, then said after a moment of silence:

"Well, such a huge soul stone is indeed extremely rare. I'm in urgent need of it right now. Let's make the exchange according to your suggestion."

When the other cultivators in the attic heard the answer from Master Tianjing, they were all very surprised. They all looked at the egg-shaped crystal in Chen Yun's hand, their eyes full of curiosity and confusion.

Treasures that can be exchanged for several precious puppets at one time are naturally worthy of their special attention.

Chen Yun's expression remained calm. He handed the crystal to the other party without hesitation, then lowered his head slightly and waved his sleeves lightly, and the six puppet beasts disappeared without a trace.

However, what the other cultivators did not notice was that at the moment when Chen Yun lowered his head, the corners of his lips moved slightly. The light in Tianjing Zhenren's eyes flickered, and a trace of doubt flashed across his face.

At this time, Chen Yun had already returned to his seat with the puppet.

Immediately afterwards, Master Tianjing announced the successful conclusion of the trade fair. Many cultivators stood up and left the attic. Chen Yun and others also mixed in the crowd and walked out of Jinglong Pavilion.

When the three of them left the attic, they did not talk much to each other. However, after they crossed two streets and were a little away from the attic, the Fire Dragon Boy suddenly spoke:
"My two fellow Taoists, I have another appointment to attend. I will take my leave now. I cannot continue to accompany you two." (End of this chapter)
