When I left the Magic Tower, it was afternoon.

Yun Sheng met Gu Feng on the road, Yun Sheng concealed the matter of the first prohibition, and gave a general explanation of the situation in the magic tower.

"Are you interested...... To Mentor Merry...... The Magic Laboratory...... See me configure a magic potion? Gu Feng was happy for Yun Sheng, secretly glanced at her, and embarrassedly sent an invitation to Yun Sheng.

Gu Feng is also a public student, but he only needs to be responsible for helping Mentor Mei refine potions on weekdays.

Yun Sheng hadn't started taking potions classes yet, and she had a certain interest in potions because of her study of ancient medicine.

Yun Sheng thought about it, the matter of the public medicine field has been completed, and she will be fine in the afternoon, so she will take a look at how the potion is refined with Gu Feng.

The tutors of the Potions Department all have their own Potions laboratory, and Gu Feng was the mentor of Mei Li.

Tutor Merry was not there, and the laboratory was about half the size of a dormitory for public students, and there were various materials for refining potions on display.

Yun Sheng took a look at it and found that the refining of potions was actually similar to the medicine in ancient medicine, but the refining of potions required the use of magical elements, which sounded more like medieval alchemy.

The varieties of magic materials are also varied, from all kinds of magic ores, monster soul stones, animal skins, animal bones, all kinds of magic herbs, it is unimaginable, all kinds of magic potions are refined from these materials.

"I'll refine it...... First Grade Agility Potion...... and antidote potion," Gu Feng smiled, the potion was the only skill he could use.

Gu Feng also earned his daily living expenses by selling basic potions such as agility water and antidote potions, and generally speaking, as a magician, relying on his own magic power, he could refine up to two magic potions a day.

The task given to Gu Feng by Mentor Mei Li is to have a bottle of sensitive water and a bottle of antidote potion a day.

Tutor Mei Li is also well-intentioned, refining magic potions can improve people's perception and control of magical elements, which is especially important for students in the Potions Department.

"Shall I try?" Yun Sheng was also interested in potion refining.

Yun Sheng chose Agile Water to refine.

She checked the method of making and refining the agility potion, because she had studied Western medicine when she was in medical school, Yun Sheng had only seen the recipe, and she had already quickly calculated the proportion of different materials in her mind, as well as the magic elements that might need to be consumed in the refining process.

Subsequently, Yun Sheng found a few more materials in some of the materials discarded by Mentor Mei Li, and began to extract the remaining elements in the materials, and then appropriately added the water element, controlled the size of the fire element, used the wind element to regulate the fusion of magic potions, and used the earth element as the final stabilizer.

In the process of refining, a touch of golden light flickered in Yun Sheng's pupils from time to time, and her fingertips, several magical elements of different colors fused and changed freely.

Gu Feng on the side was dumbfounded, he only felt that Yun Sheng when refining magic medicine made people even lose their eyes.

"It's done," but in a quarter of an hour, Yun Sheng had an extra bottle of orange potion in his hand.

"Oh my God...... It's really orange...... It's actually orange...... Orange Agility Potion, that...... That's medium-grade agile water," Gu Feng was dumbfounded, this is also amazing, Yun Sheng is refining magic potions for the first time.

Even if it is the same agility potion, it is divided into three, six, nine and so on, and the price on the market is also very different.

The color of the magic potion determines the efficacy of the magic potion, the blue magic potion is the first magic potion, the middle magic potion is orange, and the high-grade magic potion is red.

And this bottle of magic potion in Yun Sheng's hand, the color is pure like the warm sun in winter, a piece of orange, without any impurities, with Gu Feng's eyesight following Mentor Mei Li for more than half a month, it must be a bottle of medium-grade agility potion.

The first grade of the Agility Potion can keep people agile for five minutes, the middle grade magic potion can last for ten minutes, and the high-grade magic potion can maintain agility for fifteen minutes.

If this goes to the market, I don't know how many people will rush to buy it.

"It's really a medium-grade agility potion...... It's amazing...... Yun Sheng, you are really a god," Gu Feng looked at it carefully and swallowed his saliva violently, as if Mentor Mei Li had said that the chance of an ordinary magician refining a medium-grade magic medicine was roughly one in a thousand.

"Hehe, it's just a matter of luck, I didn't expect to be able to refine a medium-grade potion," Yun Sheng attributed the reason for refining a medium-grade potion to the cooperation of Shennong's pupil and Trillium's hand, coupled with her five-system magic soul, her sensitivity to magic elements is beyond ordinary people, and her ability to master fire is even more first-class.

"What if it's ...... Mentor Merry saw it...... She will definitely be happy," Gu Feng couldn't put down the bottle of agility potion, and took it carefully, for fear of spilling a little bit.

"No, this Agility Potion isn't for Mentor Merry, we're going to take it out and sell it," Yun Sheng blinked.

"This ...... How does this work...... This is a potion in the laboratory, "Gu Feng is an honest man, and he has never done this kind of takeout thing in the two months under Mentor Mei Li.

"We just used the waste materials here, which were originally scrap to be discarded. If you don't want to go, we can buy some new materials again," Yun Sheng enlightened Gu Feng.

"Still no...... Okay," Gu Feng stared pitifully at the bottle of medium-grade magic potion.

"Think about it, with it, how many silver coins can we exchange, even magic cards?! Don't you want to get into the magic card experience? Yun Sheng strongly felt like a wolf grandmother who seduced Little Red Riding Hood with a poisoned apple.

Isn't there anything she can't do, if she goes step by step, I'm afraid that she and Gu Feng, two public students, won't be able to save magic cards for a year.

If you can use discarded magic materials to refine high-grade or even medium-grade magic potions, it is simply a good deal to turn stones into gold.

In her opinion, Gu Feng's talent was not as bad as she imagined, he just lacked the resources to cultivate.

She wanted to give Gu Feng some moonlight grass for a while, starting with improving his magical physique.

As soon as he heard the magic card, Gu Feng couldn't help it.

Listening to Yun Sheng today, he also wants to enter the magic tower to try.

"That'...... All right...... I heard that in the academy...... There is a night market...... On weekdays, everyone will put ...... The surplus items on hand are sold at the market...... There are even some mentors who go to ...... There should be ...... You can exchange Agility Water for Mana Cards, "Gu Feng came in two months earlier than Yun Sheng, and he knows more about things in the academy.

But he still repeatedly demanded that if Yun Sheng sold the medium-grade agility potion, he still had money left, and he must buy some magic materials back.

Yun Sheng agreed to his request, and the two agreed to try their luck at the night market tonight.
