"Alright, the auction of all the items for this fair has been completed, and now it's time for you to trade freely. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

"I am here first, the next free trade, unless there is a forced buy and sell thing, otherwise the organizer will not care, if there is a situation of looking away, you are also responsible, and the organizer has nothing to do with it, okay, who will come up first?"

With that, the masked wizard stepped back and gave way to the place.

As soon as the wizard's voice fell, three figures immediately flashed and rushed towards the high platform.

In the end, a mysterious wizard with a small stature took the lead, and the other two had to turn around and return.

"I have a 'dark gold stone' in my hand, and I plan to exchange it for a 'rotten blood grass', I wonder if you have any friends here who are willing to exchange it?"

On the high platform, the short wizard took out a piece of black metal the size of a skull, put it on the table in front of him, swept the hall with his eyes, and said with a look of hope.

As a result, after a while, no one in the entire hall stepped forward, and a trace of disappointment flashed in the eyes of the short wizard.

After a few moments, the short wizard had to put away the black metal on the table, and walked down the high platform in a somewhat depressed manner.

Then another wizard hurried towards the high platform......

Half a day later, many wizards in the hall had already gone to the high platform, but very few could successfully exchange for what they needed.

Either the things taken out by the people on the stage in exchange are too low, or the many wizards in the audience are not interested in the things taken out by the wizards on the high stage in exchange.

After a long time, few wizards in the hall had come to the stage, and then Lin Meng seized the opportunity and got up and walked towards the high platform.

Standing on the high platform, Lin Meng first silently took out an inconspicuous black stone from the space ring and put it on the table in front of him, then swept over the people below and said slowly.

"This thing is of some use to me, and I don't know if any of my friends here can recognize it, what it is, or where it can be obtained in large quantities, and I will definitely give a good reward. In addition, I also purchased the rare material 'Wind Spirit Gold' of the wind system, the price is easy to say, and a set of forbidden magic circles that can protect my residence!!"

After speaking, Lin Meng stopped speaking, and stood silently on the high platform, looking at the group of wizards sitting below.

After a long time, there was silence in the audience, and no one stepped forward, and Lin Meng's eyes couldn't help but flash a touch of disappointment.

After a while, Lin Meng had to put away the black stone on the table with regret and walked off the stage with a gloomy face.

After Lin Meng, there were also several wizards who came to the stage to exchange for the materials they needed, but there were still very few successes, and after a while, no one was on the stage, and the masked wizard who was originally standing on the side immediately stepped forward.

"Since there is no one on the stage, I announce that this underground trade fair is over, and you are welcome to come again next time!!"

With that, the masked wizard and the other two turned to enter, and the wizards in the hall began to get up and leave one after another.

Of course, the fastest to leave was the old wizard who had bid for the 'shaping potion', and the masked wizard's voice had just fallen, and his figure had disappeared from his seat.

The next moment, he saw his figure appear by the door outside the hall, and as soon as the door opened, the old wizard flew away.

At the same time, in the hall, watching the departure of the old wizard, several people quickly got up and followed closely.

Not all the wizards in the hall hurriedly chose to leave, but some of them stayed behind, or walked towards the wizards they had already looked for, but there was no voice between the two, they were all talking in secret arts.

At this time, after sitting for a while, Lin Meng was ready to get up and leave, although the information of the black stone was still nothing, but the biggest purpose of this trip had been completed.

Thinking of this, Lin Meng's fingers gently stroked the flame ring on his hand, which contained the alchemy blueprint of the advanced microscope that Lin Meng had acquired just now.

"Eye of Alan!!"

This is the name of the microscope on the design drawing that Lin Meng bought, according to a series of complex calculation formulas and rune arrays listed on the drawings, it is indeed worthy of being designed by a second-level wizard, Lin Meng is secretly happy in his heart.

Although it seems that it will take a lot of work to successfully produce this advanced microscope, after a rough estimate of the earth.

Lin Meng was already able to determine that the 'Eye of Ailan' in his hand could definitely achieve the accuracy he required, and it was even much more advanced than Audrey's wizard's microscope.

Thinking about these things in his mind, Lin Meng didn't stop, got up and walked out of the hall.

Just a few steps away, suddenly Lin Meng's figure froze, his eyebrows raised, and then Lin Meng remained silent, his body turned, and he walked towards a sitting wizard on the side.

"Just now, Your Excellency stopped me and said that you want to make a deal with me, I don't know what you mean by the transaction?"

I saw Lin Meng walk straight in front of a wizard who was not tall and a little chubby, and asked the wizard in front of him directly through sound transmission witchcraft.

"I know the origin of the black stone that you took out earlier, so I want to make a deal with you, I wonder if you are interested in hearing it?"

When the short and fat wizard heard this, his eyes flashed, and he stared at Lin Meng carefully.

"Oh, I am a little interested in hearing your Excellency say this, I don't know what kind of transaction it is, I would like to hear about it!!"

Although Lin Meng's heart was shaken, his tone was still calm, without any surprise, staring at the short and fat wizard in front of him and said calmly.

"I can tell you all about that black stone, but in return, you have to do it for me once, against a first-level creature, how about it?"

Suddenly, the short and fat wizard, with a roll of his eyes, said to Lin Meng with some cunning.

"Hmph, don't you think you're fooling around?"

When Lin Meng heard this, he couldn't help but sink his voice, and said angrily.

"With just a few words, you want me to take a huge risk to deal with a first-level creature who knows nothing, and I don't know if the information you said is true or false!!"

"Hmph, Your Excellency's deal is too cost-effective!!" After speaking, Lin Meng laughed angrily.

If it weren't for the black stone, it would be too important for the 'giant gold beetle' in Lin Meng's hand, and Lin Meng would have left long ago.

"Your Excellency doesn't have to be so angry, the transactions are all negotiated, since Your Excellency feels that you have suffered a loss, then I still have a set of alchemy items in my hand for the 'Dark Blood Vine' forbidden magic circle, this is a treasure that I have collected over the years, the second-level wizard dare not say, but as long as the first-level wizard is trapped in it, he will not want to get out of the way, I don't know what you think with this condition?"

Feeling Lin Meng's anger, the short and fat wizard smiled lowly, and then told the words he had prepared.
