"Mr. Lan, if you have something to do, you can leave first. Our residences are not far from each other, and we will have many opportunities to meet in the future." Lu Luo replied with a smile on his face.

"Then I'll take my leave!" The Fire Dragon Boy didn't waste any time. He said goodbye to Chen Yun and turned to walk towards another street.

Chen Yun watched the boy disappear from his sight and couldn't help but smile and comment: "Fellow Daoist Huolong is indeed interesting!"

"Because Donor Lan accidentally ate a strange herb when he was young, his appearance and body shape remain at the level of a child, but he has an open-minded and sincere personality, and stands out among the new disciples. Moreover, he is the only Ancient Sword Sect elder who has good intentions towards our Luoyun Sect."

He thought to himself: "It seems that the other elders of the Ancient Sword Sect are not friendly to our Luoyun Sect."

Lu Luo looked around and asked Chen Yun, "Brother Chen, what are your plans next? Are you going back to rest or continue shopping?"

"I plan to buy some special materials needed for making talismans. There might be some surprises."

Chen Yun spoke frankly.

Lu Luo agreed: "I also plan to go to the auction house to bid, so let's part ways here."

So the two said goodbye here and arranged their own itinerary.

The several sub-markets in Tiantian City are very large, even larger than those of the three sects in Yunmeng Mountain.

Chen Yun strolled in the west market, constantly observing the shops on both sides.

What they said about purchasing materials for making talismans was not empty talk.

Chen Yun planned to purchase some scarce talisman-making materials in preparation for refining high-level talismans.

Although he already had a large amount of spirit beast skins and blood, he still needed some additional ingredients to refine high-level talismans. This was also a preparation for his future research and production of spirit summoning talismans, and a chance to improve his own talisman-making skills.

The power of the spirit summoning talisman is amazing, enough to save one's life in a critical moment, and Chen Yun is unwilling to miss this opportunity. However, the process of making the talisman is extremely challenging, far more than the ordinary five-element talisman.

In order to increase the success rate, he not only needs to improve his talisman-making skills, but also needs to replace it with a better talisman-making pen. The original talisman-making pen is outdated and can no longer meet the needs.

Unfortunately, it is not easy to find high-quality talisman-making pens. There are several shops in the first two markets that sell talisman-making pens, and even rare top-grade talisman-making pens, but after seeing them, everyone shook their heads and left.

These talisman-making pens may be used to make ordinary high-level talismans, but they are still insufficient for drawing secret talismans such as summoning talismans.

The talisman-making pen is a spiritual tool used exclusively by talisman makers. It is not common and most of them are mid- to low-end products.

For a talisman maker, if his mana reserves are insufficient and he reluctantly uses a high-level talisman-making pen to make talismans, not only will it fail to improve the efficiency of talisman-making, but it will greatly increase the possibility of failure.

Since talisman makers often focus on practicing the art of talisman making, their cultivation is generally low, and most of them still remain below the foundation-building stage.

There are only a handful of professional talisman makers who can reach the Jindan realm in the entire Tiannan immortal cultivation world.

As for the talisman makers in the Nascent Soul stage, according to Chen Yun's understanding, it seems that such extraordinary people have not appeared yet.

In fact, after reaching the Nascent Soul stage, some senior masters will choose to study the art of talisman making on their own. They are not full-time talisman makers.

However, there are also huge differences in the talisman-making skills of these Nascent Soul cultivators.

Most of them specialize in one or two high-level talismans that are beneficial to their own practice.

However, given the scarcity of high-level spirit beast skins and high-level beast blood, the number of times they can practice in the room is bound to be limited. It is needless to say that the success rate of their talisman making is very low.

This has resulted in the price of high-level talismans sometimes exceeding that of top-level magical instruments in the world of immortal cultivation, creating a rather strange phenomenon.

The five elements spell talismans among the high-level talismans are still understandable. After all, the destructive power of most high-level spells is still insignificant compared to the use of magic weapons.

Therefore, after forming the elixir, monks usually choose to give up the in-depth practice of the five elements magic.

However, this does not mean that high-level spells are worthless in actual combat.

As far as Chen Yun knew, there were many powerful five-element spells. Once they were cast, even a cultivator in the Nascent Soul stage had to avoid them.

However, these spells are extremely difficult to practice, and even if one has some understanding of them, the actual application process is inevitably complicated and lengthy.

Instead of spending a lot of time practicing these spells, it would be more convenient and effective to attack directly with the help of magic weapons.

However, the mages of the Mulan tribe seemed to have broken this shackles.

They have developed many powerful instantaneous spiritual arts that can compete with ordinary monks without the aid of magical weapons or talismans, greatly improving the strength of low-level mages.

With the help of spiritual arts, high-level mages can double the power of their magic weapons, which undoubtedly enables them to easily defeat other monks of the same level.

Because of this, although the major forces in the Tiannan region joined forces to resist the invasion of the Mulan tribe, they could only protect themselves and it was difficult to achieve the feat of completely defeating their opponents.

While pondering these questions, Chen Yun strolled along the streets of the market town, occasionally looking at the larger magic weapon shops and grocery stores on both sides.

Normally, only large shops would be able to sell niche magical tools such as top-grade talisman-making pens.

Almost without exception, smaller stores are unable to provide such products, let alone top-grade talisman-making pens.

Perhaps there are indeed some precious items hidden in some small shops, but Chen Yun is not willing to spend a lot of time searching for them one by one.

You know, there are a large number of shops in Tiantian City. If you want to visit them one by one, it will probably take more than ten days to complete.

Chen Yun strolled around quietly, passing by one large store after another, and no one noticed his presence.

When he walked out of a tall attic with a slight regret, more than half of the time had passed quietly.

Looking at the sky which was already getting dark and the moonstones gradually lighting up in the shops, he whispered to himself, "Looks like I have to hurry to keep my appointment."

After saying this, he immediately used his body skills to fly towards a specific location in Tiantian City.

Not long after, Chen Yun appeared in front of the building he had visited during the day.

He glanced at the plaque on the door with the three golden characters "Jinglong Pavilion" engraved on it, touched his chin lightly with his fingers, then stared at the door shrouded in night for a moment, and stepped in without hesitation.

"Welcome Mr. Daoist Chen to visit our pavilion again! I didn't expect that Mr. Daoist Chen would be so trustworthy and arrive at the agreed time."

As soon as Chen Yun walked into the attic, the room was instantly brightly lit. Zhenren Tianjing was sitting behind the long table as if it was daytime, looking at him with a smile.

"Since I took the initiative to invite you, how could I break my promise? But looking at your appearance, it seems that you have been waiting for a long time, which really makes me feel ashamed!"

Chen Yun responded calmly, and then he waved his hand gently, and an invisible force pushed the door of the attic to slowly close. Upon hearing this, Master Tianjing smiled slightly, and then said:

"When Fellow Daoist Chen left during the day, he suddenly sent me a message, saying that you still have the Soul Stone. Is this true?"

After saying this, the old Taoist narrowed his eyes slightly, as if he was skeptical about the news.

Chen Yun did not answer immediately, but reached out and patted the storage bag. As his palm flipped, a crystal stone of the same size as the soul stone he saw during the day appeared.

Its surface was emerald green, emitting a chilling aura that made one's heart palpitate. He stared at the old Taoist priest without saying a word.

"What Daoist Chen said is indeed true. I wonder how many soul stones of this grade Daoist Chen still has? I am willing to exchange my entire fortune for them. Whether it is spirit stones or various materials, as long as Daoist Chen asks, I will do my best to satisfy you."

When Master Tianjing saw that Chen Yun indeed had such a high-quality soul stone in his hand, a look of excitement suddenly appeared on his face and he spoke anxiously.

"Fellow Daoist Tianjing, there is no need to be so anxious. This time I took out the Soul Stone with the intention of trading with you. However, before that, I still need to ask you two questions. As long as the answers satisfy me, this Soul Stone will be considered a gift from me to you."

Chen Yun said in a steady tone, and at the same time handed the soul stone in his hand to the other party.

Tianjing Zhenren took the soul stone with some surprise, and carefully observed the object in his hand, with doubt in his eyes. He was silent for a moment, then sighed and said:

"Fellow Daoist Chen is so generous! It seems that the question you raised must be very important. But as long as I can answer it, I will definitely satisfy you.

As soon as Master Tianjing finished speaking, he carefully put away the soul stone in his hand, and his expression returned to his previous calmness.

"Since you said so, I will not be modest any more. May I ask if you know any information about the divine thunder? At the last exchange meeting, when I mentioned that I wanted to buy information about the divine thunder, you seemed a little nervous. I'm afraid you have learned some inside information."

Chen Yun did not hold back and asked questions directly and frankly.

"Indeed, although I know a little about the information about the divine thunder, I am not completely sure. Therefore, in order to avoid misunderstanding, I did not disclose it at the exchange meeting. If Fellow Daoist Chen is really interested in this, I will tell you the truth."

There was no surprise on Master Tianjing's face, but he answered calmly.

"Even if the news is wrong, Chen is willing to listen to it. Please feel free to tell your story."

Although Chen Yun was mentally prepared, a smile still appeared on his face.

"It is said that the divine thunder was discovered in the Fallen Demon Valley, where the environment is extremely dangerous!"

While recounting the story, Master Tianjing shook his head gently: "If Daoist Fellow Chen is unfortunately caught in it, it would be really worrying."

Chen Yun's eyes flickered. He had never expected that the divine thunder he had been pursuing would actually appear in the Demon Valley.

After merging the Five Elements Divine Thunder into Five Elements Divine Thunder, Chen Yun had the possibility of regaining control of the Four Divine Thunders.

However, he has not been able to find a suitable divine thunder so far. Now that he has learned the clue of the divine thunder, he is naturally unwilling to give up easily.

"So, what type of divine thunder is it?"

Chen Yun's eyes flickered as he looked at Master Tianjing and asked.

"I can't be sure either."

Tianjing Zhenren shook his head slightly: "The only thing that can be confirmed is that it is closely related to space."

"Space God Thunder?"

No matter what type it is, as long as it involves the space field, it must be extraordinary.

"As long as Fellow Daoist Chen gives me a soul stone, I will tell you the exact location of this divine thunder."

Seeing Chen Yun showing great interest in the divine thunder, Zhenren Tianjing's eyes flickered and he suddenly made a request.

Chen Yun nodded. For him, a soul stone was not a difficult task.

"Thank you for your guidance, Immortal. The next question I want to ask is closely related to the Soul Stone. I sincerely hope Brother Tianjing can give me the answer."

"Fellow Daoist Chen's words really make me confused and puzzled!"

The old Taoist priest, who seemed amiable at first, suddenly changed his expression after hearing Chen Yun's words. His eyes flashed with a sharp light and he asked in a heavy tone.

"I'm really sorry. Chen has some knowledge of this and knows the art of puppet making. He even found the remains of ancient puppet beasts in the caves of ancient monks, among which there were soul stones hidden. If nothing unexpected happens, these soul stones should be the key materials for puppet making. Considering that the real person collected these soul stones, he may have mastered the ancient puppet making method and wanted to make a powerful ancient puppet. I wonder if what I said is accurate? I would like to hear your opinion."

Chen Yun looked straight at the old Taoist and spoke without blinking.

However, as soon as he said this, he suddenly felt a sense of alarm in his heart, and he had to be on guard against the old Taoist priest suddenly attacking him out of anger and humiliation.

After hearing this, Master Tianjing's expression remained normal, but his eyes became even colder. He remained silent, staring at Chen Yun with a sharp gaze.

Feeling the increasing pressure, Chen Jianli took action and took out a jade box about the size of his palm from his storage bag. Chen Yun carefully opened the lid of the box, and two crystals larger than the previous soul stones slowly emerged from the box.

Tianjing Zhenren's body was shaken, his expression relaxed, and his eyes flashed with surprise.

"Where did you get such a large amount of soul stones? Do you have any left?" The old Taoist looked doubtful and questioned Chen Yun solemnly.

Chen Yun responded calmly and smiled without saying anything.

"Okay, I can answer Fellow Daoist Chen's questions, but please tell me the truth about the source of the soul stone."

The old Taoist tapped the table lightly to show his sincerity, and then looked at Chen Yun with the same seriousness.

"make a deal!"

Chen Yun responded without hesitation.

"Just as fellow Taoist said, I and several of my companions discovered the relevant puppetry refining methods in the ruins of ancient practitioners. According to records, puppet beasts are powerful, but they need to be made with rare raw materials and must be used in conjunction with soul stones to be successful. However, soul stones are extremely rare, and not many have been found so far. Therefore, we rashly exchanged them at the exchange meeting. Then, can Immortal Chen tell me why you have so many soul stones?" Zhenren Tianjing asked calmly after giving a general account.

"In fact, my soul stone comes from the Yinming beast. This kind of monster is indeed rare, and it must be difficult to find its trace." Chen Yun answered very frankly.

"The Yinming Beast? I've never heard of it. Where can we find this beast?" After hearing this, the old Taoist's eyes flashed with excitement and he couldn't help but ask.

"I wonder what kind of puppet you want to make. Can you let me see the puppet technique you have obtained?" Chen Yun asked calmly. (End of this chapter)
