Materials like this containing the power of laws may be very precious to ordinary immortal cultivators in the realm of true immortals, but they are nothing to Yang Feng. He now has several such materials.

The old man in green robe spoke, "I didn't expect that there was such a treasure in my hand, but you haven't said what you want to exchange for?"

The bald man looked at the people around him and said, "I want to exchange for the same level of metallic materials, or the core of a metallic realm monster."

Everyone was silent when they heard this, and no one spoke.

The previous few people who wanted this thing smiled bitterly and shook their heads helplessly. Although the things were good, the things they asked for were also very rare.

The bald man frowned immediately when he saw this.

An old man wearing a hat asked, "I don't have these two things that fellow Taoist said. I wonder if you would like to exchange them with fairy stones?"

The bald man put away the box, closed his eyes and said, "I don't lack immortal stones. Since no one takes out the materials I need, then let it go."

"What I brought is some materials for the monsters in the real immortal realm. I want to exchange for some elixirs for diligent cultivation."

A young woman wearing a veil next to the bald man stood up at this time, waved her hand, and five green bones appeared on the table, emitting a faint green light.

The monster materials were not very precious, and everyone took a look back and had no interest.

However, after all, it was the material of a monster in the real immortal realm, and someone wanted it, but in the end, a dragon gate elder exchanged two bottles of elixirs.

The person behind the young woman is the field mouse.

The field mouse coughed and said, "Fellow Taoists, this time I brought this set of banners with 7, 49 sides, each of which can be called the level of spiritual treasures. The main banners on three sides are even the best spiritual treasures. If the forty-nine sides are used at the same time, the power is comparable to that of ordinary immortal weapons. I want to exchange for one piece of demon spirit and heavenly crystals."

The field mouse waved his hand and flashed black light in front of him, and there were black banners the size of a palm, with a total of forty-nine sides, three of which were obviously much larger than the others.

The field mouse pinched the magic trick in his hand, and a dark cloud as dark as ink erupted from the black banner, instantly filling the entire hall. A sound of ghosts and wolves howling came out of the dark clouds, and the void trembled.

Everyone present couldn't help but be surprised when they saw this.

Yang Feng also took a look at this set of banners. This set of banners is the most precious thing so far.

Although this magic weapon is quite powerful, Yang Feng did not have the idea of ​​exchange for it.

Although Yang Feng was not moved, the others were very jealous. After a fierce round of bidding, the thing was finally exchanged for a piece of demon spirit and two thousand top-quality spirit stones by an outsider cultivator, plus a few precious treasures.

The voles brought the trade fair to a peak. The treasures brought out by the next few people were extraordinary, and they were all very beneficial to the cultivators in the realm of the true immortals. The atmosphere of the trade fair gradually became warmer.

The most precious one is that a man in the middle stage of the True Immortal took out three purple flowers, called purple mandalas, which contain extremely poisons that can kill immortals in the True Immortal Realm. However, this is the material for refining highly toxic magic weapons, which is very precious.

This person wanted to exchange for the demon core of a true immortal monster called the Red Crown Fire Crane, but unfortunately no one here could get it.

As time goes by, the atmosphere of the exchange meeting gradually reaches its climax.

Qi Liang was in front of Yang Feng. He was lucky. He used two good spiritual treasures to exchange for a spiritual herb that was 100,000 years old. I don’t know what to use for.

After a while, it was finally Yang Feng's turn. His hand brushed across the table. A flash of light appeared on the table, two more things were a black ball and a red crystal as big as a human head.

The black ball among them is the demon core of Zhong Ruan's black crane, and the red crystal is the crystal containing the law of fire obtained from the thin old man.

Yang Feng later investigated this object and found out that it was a material called Feiyun Fire Crystal. Although it contained the power of the fire attribute law, it was naturally unable to accommodate a large amount of fire spiritual power, so it could not be used to refine magic weapons and immortal weapons.

However, in contrast, this thing has another wonderful function, that is, it can tame the spiritual power of fire.

The spiritual power of fire is generally extremely violent, but no matter what kind of explosive fire spiritual power, it will become very gentle and weak if it is transmitted through the Feiyun Fire Crystal.

Because of this characteristic, the Feiyun Fire Crystal is one of the best materials for refining alchemy furnaces or refining furnaces. If you only need to add some Feiyun Fire Crystals to a general alchemy furnace, the stability will immediately increase. The Feiyun Fire Crystal in front of you is so big that it can be enough to refine a superb alchemy furnace. If you get some sects that are good at refining alchemy and refining weapons, you will definitely be sold at a sky-high price.

Compared with the Feiyun Fire Crystal, although the black demon core is also very precious, it is much less valuable.

The old man in green robe was stunned at first, and then his breathing became heavy. He looked at the red crystal tightly, his eyes not blinking, and his cheeks became a little red due to excitement.

Although the others did not recognize Feiyun Fire Crystal, they also guessed that Feiyun Fire Crystal was a rare treasure, so they sent a message to ask.

"The demon core of the true fairyland monster is a piece of Feiyun Fire Crystal. The demon core is exchanged for the ten thousand wheel fruit and the blood crystal lotus root. The year of the two materials is more than 50,000 years. Feiyun Fire Crystal wants to exchange the floating fruit, Tianzuo Ginseng, Lucondensing Grass... The nine materials of Tianhan Gum. As for how to exchange them, you can discuss it again." Yang Feng said Youyou.

After hearing Yang Feng's words, everyone's excitement disappeared, and their faces showed a strange look, and no one spoke for a while.

"This fellow Taoist, there is one of Wanlun Fruit in his hand, but there is no blood crystal lotus root. I wonder if it can be replaced with something else?"

At this moment, a voice sounded, but it was the old man in the middle stage of the True Immortal, looking at the black demon core.

"Oh, let me take a look at your Wanlun Fruit first."

Yang Feng said lightly when he heard this.

The old man in white robe took out a blue wooden box, but did not throw it over immediately. He looked at the black demon core and said, "Can you let me check one or two of your demon core?"

"sure."

Yang Feng smiled faintly, waved his hand and emitted a green light to lift the demon core and flew to the old man in white robe.

Seeing this, the old man in white robe threw the wooden box over.

A talisman was pasted on the wooden box. Yang Feng waved his hand and a blue light flashed by. The talisman on the wooden box immediately fell and the lid opened automatically.

A light golden spirit fruit the size of a fist was lying inside, with circles of wheel-shaped patterns on the surface of the spirit fruit. Although there was no strange fragrance, there was an unusual vitality coming to my face.

Yang Feng gently picked up the spirit fruit, looked at it briefly, and nodded.

This thing is the Wanlun Fruit, which is at least 60,000 to 70,000 years old, which is enough to be used for alchemy. The fruit core inside is not damaged at all, and there is no problem in cultivating it separately.

The old man in white robe checked the black demon core and a hint of satisfaction flashed in his eyes. With a wave of his hand, four or five jade boxes of various colors appeared in front of him.

"Although I don't have blood crystal lotus, these things are not bad at all compared to them."

The old man in white robe waved his hand again, and a faint white light flashed by, and the jade boxes opened automatically, revealing the things inside.

"Essential gold wire, tiger-eyed jade, green ivy fruit... Although these things from fellow Taoists are of good quality, I don't need them, so I'll just convert them into immortal stones."

Yang Feng glanced at him and said directly.

As a result, the two of them finished exchanging, and the voice of the old man in the green robe also rang out.

"Fellow Daoist Yang, Tianzao Ginseng, Tianhan Gum and other things are too rare. No one seems to have them. I wonder if this piece of Feiyun Fire Crystal can also be exchanged with spirit stones?"

While the old man in green robe spoke, Yang Feng noticed that another eager look also looked at him, but it was the field mouse.

Seeing Yang Feng looking at him, a slightly flattering smile appeared on the voles' face.

"Sorry, this Feiyun Fire Crystal is only used to replace the materials I just mentioned."

Yang Feng withdrew his gaze and shook his head firmly.

"Fellow Daoist Yang, really can't discuss it?"

The old man in green robe changed his face and said unwillingly.

"This piece of Fierce Cloud Fire Crystal is impossible, but I still have some fragmented fire crystals in my hand. As long as you can provide the whereabouts of one of the nine materials I mentioned just now, you can also get one."

Yang Feng pondered for a moment and then said.

He said, his hand brushing across the table again, and two fists-sized fiery fire crystals appeared on the table.

The old man in green robe looked at the two pieces of Fierce Cloud Fire Crystals with some fiery eyes. After a while, he finally sat down dejectedly.

The voles also sat back and drooped their eyelids, obviously there was no news about this.

Seeing this, Yang Feng sighed, waved his hand and put away the three pieces of Fierce Cloud Fire Crystals on the table.

The exchange will continue, but the Feiyun Fire Crystal comes out, and the things you take out later appear ordinary and the atmosphere becomes dull.

Half an hour later, the exchange will end in this atmosphere.

Yang Feng did not stay here for a long time and immediately got up and left with Qi Liang.

The old man in green robe still didn't give up and asked again before Yang Feng left if he could exchange a piece of Feiyun Fire Crystal.

This time, the old man in green robe aimed at the two small pieces and took out many rare treasures.

But Yang Feng didn't need these things, and he refused again, which disappointed the old man in green robe.

However, he took out a transmission array plate and handed it to the old man in the green robe, so that if he got the materials or news to him in the future.

The old man in green robe was slightly excited and repeatedly promised that he would try his best to find it, so that Yang Feng would leave him one or two pieces of Fierce Cloud Fire Crystals for him no matter what.

Yang Feng was slightly surprised by the man's eagerness to seek Feiyun Fire Crystal, so he nodded and agreed, and soon left the Scorpio Pavilion with Qi Liang.

"I wonder where you are going next?" Qi Liang asked.

"I'll go to another place to take this opportunity to buy some more materials. After all, exchanges of this scale will be rare."
