"The blue liquid is so clear that I can't even see the thorny fruit residue suspended below the liquid..." The old witch looked at Jiang Feng in shock, "How did you do it!"

Mana potions are not rare. Most wizards who are proficient in potions will configure them, and the formulas are varied. As the formula of most mana potions, Thorn Fruit has an irreplaceable effect in neutralizing the toxicity of other medicinal materials, and is considered an unavoidable medicinal material.

However, the problem is that no matter how carefully grinding and filtering, the thorn fruit juice will remain in the juice of flocculents. These precipitates are not harmful in themselves, but they will enhance the wizard's resistance to mana potions within a certain period of time.

For the usual mana potion, after drinking a bottle of inferior mana potion, the effect of drinking it again in a short period of time becomes minimal. A strong pharmacist will use various methods to reduce the residue of thorn fruit in the mana potion, but some will be left.

Like these potions taken out by Jiang Feng, there was almost no residue of the thorn fruit at all. This was the first time the old witch saw it. If it weren't for identification, it was indeed a magic potion made with the thorn fruit. She would even wonder if Jiang Feng had omitted the steps to neutralize the toxic pharmacology.

The mana potion without the residue of thorn fruit will only appear after the fifth drink! The recovery effect of the first three drinks is quite considerable! Wearing three such mana potions on your body means that you have a few more chances of casting!

The secret feast is about to begin, and such potions will undoubtedly be very popular.

Jiang Feng smiled and refused to answer the old witch's question.

Realizing that his problem was a bit abrupt, the old witch restrained the shock on her face, quickly lowered her head and said sorry timidly, then took out something like a dropper, took a drop of blue liquid from the mana potion, placed it on the ceramic vessel, and sprinkled with gray powder.

From the powder, Jiang Feng smelled a trace of sulfur.

It should be some kind of technology used to identify the grade of the drug.

"The medicinal properties are perfect, with a total of twenty bottles of mana potions... I have accepted all of these potions," as if I was afraid that Jiang Feng would not be satisfied with the price. The old witch continued, "Of course, if you think the price is low, you can choose to consign. We only charge a 10% handling fee. This may be sold at a higher price, but the secret feast is about to begin, and I guess you don't want to wait too long."

Jiang Feng was secretly surprised. It was not because the old witch guessed what he was thinking, but because he didn't expect these potions to be sold at such a high price.

There are ten low-level magic stones in a bottle of potion. You must know that even a magic stone is difficult to find in the secular kingdom. He only found one hundred low-level magic stones in the ruins of Dr. Z!

After all, that is also a legacy left by a time traveler!

Now Jiang Feng understood a little why wizards in this world rarely interfered in mortal things, because few mortals could afford to ask them for help. In this way, Flynn seemed to have picked up a bargain and bribed himself with a thorny wasteland.

Thinking of this, Jiang Feng couldn't help but sigh.

I don't know what's going on with the college.

"make a deal."

As if Jiang Feng was afraid that he would regret it, the old witch quickly put away the twenty magic potions and placed the wooden box containing two hundred magic stones on the table. Jiang Feng simply scanned it with his intelligence brain and put it into the space ring.

"If you have new pharmacies to sell, please be sure to consider our Wesen family." The old witch said respectfully in a deal, "Our Wesen family is friends of all pharmacists, whether it is consignment or acquisition, I believe we can give you a reasonable offer."

As for snatching the secret recipe from Jiang Feng, the old witch had never considered it.

If he is a wizard apprentice, it would be fine. As long as he follows him and moves around and silently solves him, he can still do something similar. Not only have they done it, but other wizard families have also done it.

However, the opponent is a formal wizard with more than one star, so it must be treated with caution. After all, no one knows whether the other party has a backup plan. For the sake of a potion, the deal is not that cost-effective.

After all, it is said that it is the wizard family, but there are only a few who have the strength of a wizard. She counts one by herself, and the elders and patriarchs in the clan are also counted one by one, but the other clan members are only apprentices at most, and most of them are ordinary people.

A formal wizard wants to kill a few ordinary people, which is no different from killing a chicken. If he let go of his hands and feet and takes revenge in a crazy way, no matter how big the family is, he will not be able to bear it.

"I will consider it." Jiang Feng nodded slightly and continued to ask, "Also, I plan to buy something. I wonder if you have the eyes of the Soul Eater here?"

"...this," the old witch looked a little embarrassed and shook her head, "The Soul-Eating Monster is a creature that is only found in the Wizard Continent, and the giant wheel of the academy has not visited this world for a long time. The secret feast is about to begin. Maybe you can try your luck in the secret realm?"

It seems that I have to go to the secret realm?

After thinking for a while, Jiang Feng nodded to show that he knew, and then turned around and left Grandma Karan's potion cottage and walked towards the center of the market.

...

The slave exchange is located in the center of the small town of Wanshi. A few big words are blatantly written on wooden signs, and passers-by are accustomed to this. It can be seen that the slave trade is not excluded. If it were in the Kingdom of Rick, although the existence of slaves was recognized, the slave trade was strictly restricted, and it was impossible to openly sell slaves in the center of the city.

In Wanshi Town, the slave trade can be said to be one of the most popular industries, especially during the magic tide period, where wizards from all directions gather here. Many slave merchants will visit here in advance and prepare sufficient high-quality sources of goods.

Most wizards are busy with experiments and find it difficult to take care of themselves in life. Compared with the servants of the employed system, slaves are more convenient to use by contractual witchcraft. Not only that, using slaves to conduct experiments will not have the influence of infamousness. After all, slaves are the private property of slave owners. As long as they are not in public, no matter how they are dealt with, they will not be slandered.

The slave exchange is divided into two parts. The slaves with lower quality are tied up in the shack next to them by iron chains and sold like animals. The slaves with better quality are all in marble houses, dressed in appropriate clothes and are for people to choose from.

Slaves with advanced or above strength are naturally impossible to be in the shack outside.

Without thinking too much, Jiang Feng walked directly into the marble house.

And just as he stepped across the threshold, the slave merchants on both sides enthusiastically came up to him.

"Sir, what kind of slaves do you need? We have sufficient supply here, whether it is a well-behaved and charming princess or a beautiful and charming cat girl, we can provide it."

"Sir, come here to take a look. This is the princess of the Principal of Svetir! Svetir's white rose! It is said that he has an engagement on his body, and was captured by pirates on the way to visit relatives in the Cadylan Empire. Hehe, the most important thing is that this person is still in original goods, only three... Oh no, two magic stones!"

"You are here to attend the secret feast, right? Look at this orc warrior! You have the blood of the highland white cow. Although you have some problems with your head, you can be a meat shield! Just two magic stones are enough!"

Jiang Feng noticed that the people who bought and sold slaves here were all mortals, but they collected magic stones.

Looking at the three-meter-long tauren warrior, Jiang Feng simply scanned it with his intelligence brain, then shook his head.

Muscle strength (strength) 3, reflex nerve (agility) 2.

From the perspective of attributes alone, based on the standards of warriors in this world, they can barely reach the level of advanced warriors. The price of two magic stones is indeed not expensive. However, this guy is not having a problem with his brain, but a severe concussion. Whether he can fight or not is still a big deal. If he buys it back, he will definitely lose money.

"Are there any slaves with master level strength, preferably knights or warriors?" After pausing for a moment, Jiang Feng glanced at the man meaningfully and continued, "Also, don't fool me with such an idiot."

"Yes, I'm sorry..." The man burst into cold sweat, lowered his head tremblingly, and smiled and did not dare to speak.

Obviously, he knew the problem with the tauren.

Jiang Feng ignored him and was about to continue walking forward.

However, before taking two steps, the steps stopped.

His eyes remained at the corner, and Jiang Feng raised his eyebrows with interest and asked.
Chapter completed!
