The black shadow spoke, "A piece of thunder crystal is exchanged for a thunder-attribute immortal weapon, or three hundred immortal stones, and a ball of yin mud is exchanged for a 100,000-year-old dragon ginseng."

When Yang Feng heard this, he couldn't help but smile bitterly.

Yang Feng originally thought that his knowledge had increased greatly after joining Longmen, and he also knew a lot about various materials in the fairy world. Now it seems that he still knows too little. He has never heard of these two things in front of him.

Yang Feng's eyes swept over the two items, stayed on the black mud for a while, and then quickly looked away, and finally landed on the purple crystal.

The black mud can tell at a glance that it is a kind of yin thing and has no effect on Yang Feng at present.

This purple crystal gave Yang Feng a familiar feeling. This thing contains the power of lightning and lightning, which is very similar to the purple lightning in the purple bead.

The more Yang Feng looked at it, the more he felt the similarity, and he couldn't help but secretly guessed, was this thing also from the ocean of lightning?

Moreover, although this purple crystal is not very large, the power of lightning contained in it is terrifying, and it seems to be much richer than that of my purple bead.

In the deepest part of the purple crystal, a faint wave of soul emanates from the waves, as if the power of lightning is too strong, and some spiritual intelligence is born.

Yang Feng looked at the purple crystal carefully and thoughtful on his face. Suddenly his body shook and a voice rang in his mind.

"Master, this thunder crystal must be photographed. This thing will be of great use to me."

The Golden Bee Queen woke up at some point and contacted Yang Feng through her divine thoughts.

Speaking of which, since the last time the Golden Immortal Puppet was fused, the Golden Bee Queen has been in a sleepy state. Yang Feng tried to contact him several times before, but he had not received any response.

Yang Feng asked in a voice transmission: "What exactly is this thunder crystal and what is its use to you?"

King of Golden Bee explained: "Thunder crystal is a special crystal that can only be born in places where the power of lightning is very strong. In addition to the rich power of lightning, there is also a special soul power. This thing is not only helpful to those who practice thunder and lightning skills, but other immortals wear it to nourish the soul, which can avoid interference from the inner demons. These days, I have been working hard to completely integrate with the Golden Immortal Puppet, but it has been progressing slowly. This thing is of great help to me. With it, I can quickly master this Golden Immortal Puppet."

When Yang Feng heard this, he moved his heart and said, "So that's how it is, I understand."

Just as Yang Feng was communicating with the King of Golden Bee, other cultivators were constantly using their own methods to look at the two items on the stage, but no one spoke, as if most people had never heard of these two things.

The black shadow stood on the stage without moving, without speaking, or urging everyone.

A moment later, an immortal cultivator spoke, "Don't you introduce these two things? I'm sorry for being ignorant, I've never heard of these two things."

The black figure said lightly: "I only exchange these two things for those who know the goods!"

The cultivator in the audience sneered when he heard this, and then stopped talking.

At this moment, a white shadow flashed, and a figure flew to the high platform, and a figure appeared, which was Yang Feng.

"I want Lei Jing. This is the three hundred immortal stones. Please hold it away."

He took out a storage bag and threw it to the black figure.

"Wait, I have a thunder attribute immortal weapon made of thunder steel to exchange for this thunder crystal."

At this moment, another cultivator with a somewhat obese figure also flew to the high platform and took out a purple-green fork with lightning on it, which was extremely dazzling.

The black figure was stunned for a moment, looked at Yang Feng's storage bag and the purple blue fork, then put away the storage bag without saying a word, and handed the thunder crystal to Yang Feng.

"Wait, this fellow Taoist, if I guess correctly, you should want a thunder attribute immortal weapon, right?"

The fat cultivator's face changed and he quickly said to the black figure.

"That's right. But you're a little late." The black figure still said in a faint tone.

"Your Excellency, don't regret it!"

The fat cultivator was stunned when he heard this, and looked at the black figure up and down, as if he didn't expect the other party to do this, but he still turned his hand and put away his purple-green fork, turned around and flew back to his seat.

Yang Feng looked at the black figure and was also a little surprised, and then he turned into some admiration. People who could stick to what they said and do so to such a level, whether in the past, the Five Elements Universe, the Spirit World, or the Immortal World today, are already very rare.

After all, for a high-level immortal cultivator in the middle stage of the True Immortal Realm, it is only a matter of time before it is willing to spend energy and save up 300 immortal stones, but a common immortal weapon may not be possible, especially an immortal weapon containing the laws of thunder.

The other party may be like the King of Golden Bee, and is also a person who knows the value of "Thunder Crystal", but he is a little reluctant to give up on his thunder attribute immortal weapon, which gives him the advantage.

While these thoughts flashed through his mind, he nodded at the black figure and returned to his seat.

"Give me Lei Jing quickly."

As a result, as soon as Yang Fengfang sat down, the golden bee's voice was heard in his mind.

Yang Feng didn't say much, but with a thought, he sent the thunder crystal in the storage space to the King of Golden Bee.

A golden lightning flashed on the Queen of Golden Bee's body, and the thunder crystal penetrated into her body and disappeared.

However, when Yang Feng returned to his seat and sat down, he was slightly stunned.

The seats of the voles next to him were empty, and this person left here at some point.

He looked around and there were no voles everywhere in the venue, and it seemed that he had really left here.

Yang Feng frowned slightly, but then he stretched out again.

On the platform, the black figure waited for a while. After seeing no one making a sound, he picked up the box of yin mud and jumped down.

Seeing this, Yang Feng immediately stood up, moved his body and was about to fly onto the stage.

"You are Fellow Daoist Yang, right?"

A cold voice suddenly came from the side, and together with the fragrant wind, a figure shrouded in white light sat down and sat down in the position of the field mouse, but it was the female cultivator who had just paid a high price to buy the residual map of the Styx.

"Who are you?"

Yang Feng stopped and asked with a frown.

"Can you delay your honor for a little time?"

The female cultivator did not answer Yang Feng and chuckled.

Yang Feng hesitated for a moment, then sat down and nodded.

"The little woman just saw that you were trading fire crystals with the fellow Taoist who just sat here. I wonder if I should have this kind of fire crystal on my body. I need this thing in urgent need. I wonder if I can give up? The price will never disappoint you. As big as the fist just now, the little woman is willing to produce a hundred immortal stones, and the more it is, the more it is better." The female cultivator said sincerely.

"Your Excellency seems to know very well how many fire crystals I have on me. You also know my last name. Did the voles tell you?"

When Yang Feng heard this, he asked calmly.

The female cultivator hesitated, nodded, and said, "It's true that I just found out from that person."

When Yang Feng heard this, his face remained unchanged, but his thoughts were changing.

Although Fire Crystal is a very precious spiritual material, he has many of it. This thing is currently optional for him, and it is also possible to sell it in exchange for the immortal stone.

But maybe it will be used at any time in the future, but now it is difficult to guarantee that you will not regret it in the future if you sell it.

"Master, promise her." The Queen of Golden Bee's voice suddenly rang.

Yang Feng's eyes fluctuated for a moment, and his heart sent a voice: "Why?"

"I will tell you this matter after I completely merge the Golden Immortal Puppet. Now I agree to this person first." said the King of Golden Bee.

After saying this, the Queen of Golden Bee's voice fell silent again.

When Yang Feng heard what the Golden Bee said was a little unclear, he frowned slightly, but after just pondering for a moment, he nodded to the female cultivator and said, "Okay, I can sell it to you."

"Your Excellency is definitely a wise move. I'm afraid no one can afford this price."

Although the female cultivator's tone was still a little cold, she could hear a hint of joy mixed in it.

Yang Feng didn't say much, and whipped the storage bag with one hand.

A green light flashed, and a new storage bag appeared in his palm and handed it to the female cultivator.

After the female cultivator took the storage bag, she swept her spiritual sense, then waved her hand without hesitation, and an additional storage bag appeared in her palm and handed it over.

Yang Feng took the object, took a look, and nodded to the other party.

After the female cultivator clasped her fists to Yang Feng again, she turned around and walked towards the previous seat.

Yang Feng watched the female cultivator leave gracefully, and frowned casually.

Although he was passing through the light curtain, his spiritual sense was too strong, and he still faintly penetrated the light curtain and saw the vague figure of the female cultivator, as if he had seen it somewhere.

"By the way, it's the masked woman in red who lives next door." Yang Feng immediately recalled.

Not only that, when the woman in masked red dress met by chance, she gave him a sense of familiarity. At this moment, she met her for the second time here, and this feeling became even stronger.

At this moment, on the high platform ahead, an immortal cultivator happened to walk down.

Yang Feng didn't care about this, and his figure flashed and landed on the high platform. He took out some of the other precious materials, indicating that he wanted to exchange for the spiritual medicine needed for the Dao Dan.

Unfortunately, even at this exchange meeting, no one still had these materials.

After waiting on the stage for a while, Yang Feng had to step down regretfully.

Time passed little by little, and half an hour later, when the last immortal cultivator came down, the underground exchange finally ended completely.

Yang Feng came to the backstage and paid for the fairy stone that had previously auctioned the snow lotus roots and completed the transaction.

After a brief inspection, he carefully put it in a jade box, pasted a few talismans and placed them in the storage bracelet.

A moment later, Yang Feng's figure appeared in the city, on a secluded street.
