The apse was empty, except for a huge portal standing within the main hall.

Han Changlin pondered for a while, then came to the portal and walked straight into it, Han Changlin only felt that it was dark in front of him, and the yellow talisman in his hand suddenly disappeared without a trace.

Just between breaths, Han Changlin's eyes lit up, and he had already appeared in a stone house, there was a stone table and a stone chair in the stone house, and a set of tea sets were placed on the stone table, and I don't know when a pot of hot tea had been brewed.

Han Changlin sat down unceremoniously, and through the stone gate in front of him, he could see the outside scene clearly.

The stone gate in front of Han Changlin didn't know what was refined, and it seemed that he could only look out from the stone house, and the people outside couldn't see the situation inside the stone house at all.

Because Han Changlin could clearly see the stone houses surrounded by a circle outside, layer by layer, surrounding the central stone platform, and I don't know how many.

As soon as Han Changlin pondered for a while, he radiated his divine sense, but as soon as his divine sense touched the stone house where he was, he was bounced back, and his divine sense couldn't even disperse his own stone house.

Han Changlin's face showed a look of surprise, but his eyes were very satisfied, it seemed that Mingli had not deceived himself, the stone house of this air trade fair could indeed block the snooping of the cultivator's divine sense.

At this time, Han Changlin also noticed that on the stone table of the stone house, there was a jade plate, which was carved with very cumbersome formation stripes, exuding a faint cyan aura.

After thinking about it slightly, Han Changlin understood that this jade plate should be a channel for transporting items and spirit stones back and forth, and the person who held this air fair really took great pains to think about everything.

Since the divine sense could not probe the situation outside, how many people came in, and whether the trade fair was about to start, Han Changlin could not know anything about it, so he could only close his eyes in boredom and close his eyes to recuperate.

"Fellow Daoists."

I don't know how long it took, a voice woke up Han Changlin, who was closing his eyes and recuperating, he opened his eyes, and through the stone door, he saw that on the stone platform outside, there was already a strong man in his forties.

The strong man's eyes were full of light, although Han Changlin couldn't perceive his specific cultivation, but just from his eyes, he could know that this person's cultivation would definitely not be weaker than his own.

"Fellow Daoists, I am very glad that all Daoists have come to participate in this air fair held by our Mingyu Building."

Hearing this, Han Changlin showed a speechless expression on his face, and sure enough, as he guessed, this so-called air fair was held by Mingyulou at all, so it was not difficult to understand that Mingli introduced himself to participate.

It's just that whether this Yin and Yang Shift Order is really worth two thousand lower-grade spirit stones, Han Changlin has to consider it carefully.

"Some of the people who came to participate in the air fair are our old customers of Mingyulou, of course, there are many Taoist friends who come for the first time, but it doesn't matter, I believe that you can get the items you need at this fair."

"Below, every time I will take out three rare items reported by fellow Daoists, you Daoists can bid at will, the highest price will get, of course, if you want to barter, you can, as long as the owner of the item doesn't mind."

After speaking, the strong man waved his hand slightly, and three items appeared in the jade plate on the stone platform in front of him, an earthy yellow metal the size of a pigeon's egg, a piece of black wood with a length of a ruler, and a fiery red bead.

Han Changlin looked at the three items in the jade plate, with a puzzled expression on his face, needless to say, the first two should be the materials for refining spiritual weapons, as for the fiery red bead, Han Changlin didn't know anything.

"This piece of metal is called suction mud, it is an excellent material for refining earth-attribute spiritual weapons, which is extremely rare, as for this piece of jet-black wood, it is thunder light Yimu, which is the best material for refining wood-attribute spiritual weapons."

After speaking, the strong man pointed to the fiery red bead again, and said:

"This is an extremely rare fire spirit bead, and the fire spirit bead can not only refine high-level spirit weapons, but as long as you have enough materials, you can even refine it into a magic weapon."

"As you know, this Fire Spirit Bead can only be finally formed after millions of years of gestation in some volcanoes, and it is an extremely precious refining material, usually represented by its age."

"This fire spirit bead has more than a thousand years of fire accumulation, and it can refine a middle-level spirit weapon, of course, if a certain Taoist friend is from a large sect, he can also place this fire spirit bead in the earth fire pool of the sect, and then it can be used to refine magic weapons for thousands of years."

After the strong man finished speaking, countless numbers began to flash on the stone platform in front of him, needless to say, someone had already begun to bid for these three items.

Han Changlin didn't make a move, although these three materials are scarce, but in the final analysis, they are all semi-finished products, Han Changlin does not have the jade slip to refine the spirit weapon in his hand, even if he gets these materials, he can't refine the spirit weapon.

Han Changlin was indeed a little moved after the strong man told him the origin of the fire spirit bead, but after learning that this fire spirit bead only had a thousand years of fire accumulation, he still gave up, if he could have more than two thousand years of fire accumulation, Han Changlin would have to bid for it.

After all, the fire spirit bead with two thousand years of fire accumulation can already refine the best spirit weapon, and once the refining is successful, it will have a huge blessing effect on one's own fire spell.

"This suction mud has already been sent out by Daoists to 8,000 lower-grade spirit stones, as for this Thunder Light Yimu, there are already Daoists who have come out with 12,000 lower-grade spirit stones, and there are even Daoists who have sent out 15,000 lower-grade spirit stones from Fire Spirit Beads."

Just as Han Changlin was thinking about it, these three materials had already been photographed at the price of tens of thousands of spirit stones, which made Han Changlin secretly speechless.

And these three materials are almost more than 10,000 lower-grade spirit stones, of course, these three materials are the best materials for refining middle-level spirit weapons, once they can be successfully refined, they are naturally far from being comparable to the first-level spirit weapons.

Han Changlin had no intention of making a move, but just watched quietly, and the strong man refreshed the bidding price again and again.

In the end, these three pieces of materials were auctioned off by people for 12,000 lower-grade spirit stones, 16,000 lower-grade spirit stones, and 20,000 lower-grade spirit stones.

Soon, the price of the three pieces of material was finalized, and it was transmitted, needless to say, to the person who completed the bidding.

Then the strong man took out the three materials again and continued to start the second round of bidding.

Han Changlin watched quietly, he didn't make a move, most of the materials in front of him were some materials, Han Changlin was not interested in these materials, but he didn't have a way to refine spiritual weapons, even if he had materials, it would be useless to him at all.

An hour later, Han Changlin saw three jade slips appear on the jade plate, and his face suddenly showed an expression of interest.

The strong man pointed to one of the three jade slips and said:

"What is recorded in this jade slip is the refining method of the Wind Xuan Shield Spirit Weapon, the Wind Xuan Shield is a primary spirit weapon, but when it comes to defense, it can definitely rank in the top ten in the primary spirit weapon, and the main refining material required is the Wind Xuan Stone."

"As for this second piece of jade slip, what is recorded is the refining method of the mid-level spiritual weapon of the Tianhan Knife, and the main refining material is the Tianhan Xuantie, as for the third piece of jade slip, it is recorded that it is the refining method of the high-level spiritual weapon of the Golden Jiaodun Sword, and the main refining material is the golden reverse scale of the half-faced Jiao."

Hearing the golden reverse scales of the half-faced Jiao, Han Changlin's spirits perked up, he happened to have a piece of the golden reverse scales of the half-faced Jiao in his hand, if he could bid for this refining jade slip for refining the golden Jiao shield, he could refine another high-level spiritual weapon.

Thinking of this, Han Changlin couldn't help but use mana to input a number on the jade plate.

"Feng Xuandun's refining jade slip has already reached eight thousand lower-grade spirit stones."

"Hey, someone from the Golden Jiaodun has come out with 10,000 lower-grade spirit stones. Isn't there anyone interested in this cold knife? Okay, the Tianhan Knife also has a Daoist friend who has made a bid, and he has come up with six thousand lower-grade spirit stones. ”

"Is anyone else bidding?"

"Someone from the Golden Jiao Shield has come out with 12,000 lower-grade spirit stones."

Hearing this, Han Changlin sighed in his heart, and once again wrote a number on the jade plate with mana.

"There are Taoist friends in Jin Jiaodun who have come out with 14,000 lower-grade spirit stones, and Fengxuandun also has Daoists who have increased their price, 9,000 lower-grade spirit stones."

"Someone from Jin Jiaodun has come out with 16,000 lower-grade spirit stones, and there are still Taoist friends who increase the price?"

Han Changlin's face showed a hint of anger, and he entered a number on the jade plate again.

"Jin Jiaodun has another Daoist friend's bid, this time... Unexpectedly, 20,000 lower-grade spirit stones were produced. ”

After Han Changlin pushed the refining jade slip of the Golden Jiaodun to 20,000 lower-grade spirit stones, the monk who had been bidding with Han Changlin seemed to feel that it was not worth it and did not continue to bid.

Soon, the auction of the three spiritual weapons refining jade slips also came to an end, Han Changlin placed the cloth bag containing 20,000 low-grade spirit stones on the jade plate, the jade plate flashed blue, the cloth bag disappeared, and after a while, the blue light flashed again, and a jade slip with a light blue halo appeared on the jade plate.

Han Changlin casually picked up the jade slip, sank into his sense, looked at it slightly, and after confirming that it was the refining method of the golden Jiao Shield, he casually put the jade slip into the storage bag.

Then Han Changlin saw that the strong man took out three more items and started a new round of bidding.

After that, Han Changlin remained silent, and he didn't even make a move on the two primary-level spiritual weapons and one middle-level spiritual weapon that appeared, and several materials for refining high-level spiritual weapons appeared.

"Fellow Daoists, the items that appear below are extremely precious, and several of them are taken out by the Jindan ancestors present, and they are not seen on the market at all.

After speaking, the strong man took out a fist-sized blood-red crystal and placed it on the jade plate.

He first glanced around, and then said with a smile:

"I think many Taoist friends are very unfamiliar with this blood-red crystal, so let's explain it first."

"This blood-red crystal is called blood gold, it is an auxiliary spiritual material for refining spiritual weapons, in the process of refining spiritual weapons, if you can integrate a piece of blood gold, you can improve the level of spiritual weapons, that is to say, a beginner-level spiritual weapon, once it is integrated into blood gold, it can be directly promoted to a middle-level spiritual weapon."

"If a mid-level spirit weapon is fused with a piece of blood gold, there is at least a seventy percent probability that it can be promoted to a high-level spirit weapon, and if a high-level spirit weapon is fused with blood gold, there is a probability that it can be upgraded to a top-grade spirit weapon."

"Speaking of which, I think you also know the preciousness of this piece of blood gold, right?"
