As time went on, the exchange meeting gradually came to an end, and Persein was one of the last people to take the stage, but unfortunately this time he was unlucky, and he could not get what he wanted, so he could only walk down from the high platform with a little disappointment, and return to Aaron to sit down.

Soon, all the people who came to participate in the exchange meeting had already gone to the high platform, but in the end, less than 20 people successfully exchanged things, and only about one-sixth of them were able to do so.

Finally, the second-level mage who was in charge of presiding over the exchange meeting, seeing that the exchange meeting was almost over, stood up from the stone steps, and then walked to the high platform without hurry.

"You've all been on stage, and according to the past practice, this exchange meeting should be over, but this time I also have something I plan to exchange, so let's see if anyone can come up with something that satisfies me......" The person in charge said slowly after walking on the high platform.

"Oh! Master Karl has something to trade for!"

"It's the first time I've encountered something like this! I wonder what good things he's going to come up with?"

Carl's words immediately aroused the curiosity of many people present, and they all showed surprise.

"I didn't expect that, Brother Aaron, you would be able to encounter such a special situation when you came to the exchange meeting for the first time! You must know that I have been here several times before, but I have never encountered such a situation. Persein looked surprised and muttered to Aaron beside him.

"Has there never been anything like this before?" Aaron asked, curiously rhetorical.

"This is not necessarily, there may have been, but it should be very rare, and what the second-level mage took out to exchange it will definitely not be bad!" Bai Sein replied uncertainly, after all, he had only been here a few times, and even earlier, there might have been such a situation.

At this time, everyone's eyes fell on Carl on the high platform, and they all looked expectant, waiting to see what good things he would come up with.

Karl stood on the high platform, looked around at the people on the stone steps, then smiled faintly, and took out a small cylindrical transparent bottle, about eight centimeters in diameter and nearly twenty centimeters high.

As soon as the transparent vial appeared in Carl's hand, everyone's eyes were immediately focused on this bottle.

I saw that at the bottom of the bottle, there was some black soil, and on top of this soil, there was a small plant, from top to bottom, a total of six leaves, each of which was twisted like a hesitant wave, with jagged edges, blue rhizomes, and even the leaves were blue.

"What is this? It's the first time I've seen such a strange plant!"

"I don't know, it's the first time I've seen it, but since it's something that Master Karl took out, it must not be an ordinary plant, and it must have some origins. ”

Among the people present, no one seemed to see what kind of plant it was, and even Aaron didn't know what it was for a while, so he immediately asked the chip to look for the corresponding information in the database.

While the chip was analyzing, Aaron asked Persein beside him, "Brother Persein, do you know what kind of plant this is?"

I saw him shake his head lightly and said in a low voice: "I didn't see what kind of plant it was, and when Master Karl introduced it, we would naturally know." ”

"It seems that none of you here recognize what this is, so let me introduce it!" Seeing that no one in the room could see what he had brought out, Carl prepared to say it himself.

"This plant is not small, this is a plant called tidal flower, but because it is only a seedling, it has not bloomed, so most people should not recognize it, if it has bloomed, it is estimated that a few people present will recognize it......," Carl explained slowly.

And just as Carl was talking about the origin of the thing, the chip finally found the matching information in the database, and the result was the same as he said, the seedlings of the tide flower.

"It's actually a tidal flower, it's really a nowhere to find it when you step on the iron shoes!" Knowing that it was a tidal flower, Aaron was ecstatic in his heart, and he was several times more excited than when he saw the red flame crystal before.

Tidal flower is a special plant, when it blooms, it will produce a sound similar to the tide, with a strong hypnotic effect, even if it has reached the third level of mage, it will produce hallucinations after listening to it for a long time, which is very magical.

Moreover, the tidal flower is also a precious material, and some high-grade elixirs that enhance spiritual power generally use this flower as the main material, so in the eyes of all mages, this is a very precious thing.

Even if you don't know how to make potions, you can use them to exchange for some high-grade potions, and many pharmacists will want them.

In Aaron's eyes, the tide flower is very important, because the one he wants to make the most at the moment needs this material, and that potion is called 'Moon Dust'.

Moon Dust's recipe is an advanced formula that Aaron previously obtained from the evil dryad, which can enhance the effects of meditation without any side effects, and is one of Aaron's most wanted potions to be made as soon as possible.

The only pity is that the materials needed to make this potion are very rare and precious things, and now that he has encountered it here, although it is only a seedling, Aaron does not want to miss it.

"It's such a good thing as a tidal flower!" said Persein, who was as surprised as everyone else in the room.

Almost no one present had ever seen a tidal flower, but they had all heard of the preciousness of this plant.

"I don't think I need to explain, you all know how valuable this tidal flower seedling is, so I won't say much nonsense. I didn't specify that I want to exchange a certain item, if you feel that you have something on you that can compare to the value of this tidal flower, you might as well say it and take a look, and then I will decide whether to exchange it or not. After introducing the item's name, Carl continued.

As soon as the words fell, the people present fell silent. Because the value of the things Carl took out is very huge, it is estimated that there will be no more than five people who can really take out the exchange things.

And Aaron is also thinking about what to exchange with Carl.

After everyone was silent for a while, one of them stood up and said what he wanted to exchange, but unfortunately, what this person used for exchange did not satisfy Carl and was directly refused.

After passing through this person, another person offered to exchange something, but the result was the same.

Then, the scene fell into silence again, and Aaron hadn't thought about it for the time being, and he wasn't in a hurry, because he was sure that there was basically no one who had the ability to compete with him.

After a while, someone stood up again, this time it was a young mage, who didn't look to be more than thirty years old, but his actual age was unknown, some people looked like they were young, but their actual age was very large.

"Mr. Karl, I wonder if you're interested in potion recipes?" the young mage stood up, not saying what was exchanged, but asking Karl a question.

"As for the potion formula, I am a little interested, but you have to come up with a good formula, I have collected a lot of potion formulas here, and my vision is not low, you first tell me what potion formula you want to use in exchange......" Carl heard this, the corners of his mouth hooked a touch of arc, and he said with interest.

"I plan to use it for exchange to have a recovery potion recipe, which can speed up the recovery of mana by several times, and this effect is also effective when absorbing magic crystals, that is, the speed of using magic crystals to restore mana can also be accelerated, but the effect will be slightly weaker, only two to three times faster......" After the young mage got a reply, he said the potion formula he wanted to use for exchange.

"Well, it's a good potion recipe, let me think about it. After hearing this, Carl seemed to be a little moved, and did not refuse, but did not directly agree, but wanted to think about it.

Seeing that Carl did not refuse, the young man immediately looked happy, feeling that there would be great hope for changing to the Tidal Flower seedlings this time.

At this time, Aaron also heard the conversation just now, and knew that Carl was interested in the formula of the potion, and the formula that the young man said seemed very promising.

"Yes, then I'll also exchange the potion recipe, and it's better than that guy's, so it should work out!" Aaron was inspired by the conversation just now, and finally thought of what to exchange it for.

The youth has a potion that accelerates the recovery of mana, and Aaron has an upgraded version of the potion recipe that also restores mana, but it is not an elixir that accelerates recovery, but a potion that can directly restore mana.

This potion recipe is more direct and effective than the young man's recipe anyway, and of course, this recipe is also obtained from the evil dryad.

Aaron believed that if he had to make a choice, Carl would definitely choose his own potion recipe instead of the youth's.

Just when Carl hesitated to exchange, Aaron stood up decisively and said unhurriedly: "Mr. Carl, I also have a potion formula here that I want to use for exchange, why don't you consider it too." ”

Seeing a competitor appear, the young mage's face was not very calm, and he looked at Aaron with a frown.

"Oh, what potion?" Karl asked, interrupted by his thoughts.

"I'm going to go on stage and tell you about it, I don't want too many people to know what the recipe is. Aaron didn't answer directly, but planned to go on stage and tell Carl alone.

Because the recipe for the potion that Aaron is going to take out is more precious, and eighty percent will attract the attention of many people, it is best not to let so many people know, just tell Carl alone.

While it will attract some people's attention, at least it won't let others know too much.

After saying that, Aaron left his position and walked straight to the high platform, and Carl on the high platform was very much looking forward to this matter.
