"Alchemy is an extremely complex discipline, including magical creation, enchantment, pharmacy, scroll science, magical puppet science and other ten disciplines."

Xiwei straightened the spire mage hat on his head and said to the students in the audience: "There are many magicians who devote their lives to alchemy. Some of them have achieved fruitful achievements that are eye-catching and can only be looked up to, while others have mediocre and unknown throughout their lives."

"Of course, I'm not trying to make you proficient in alchemy. After all, there is not much content about alchemy in the Demon Jin's test except for the written test."

As a college that focuses on further studies, Huoli'an National Magic Academy has a certain degree of correlation with the Magic Elementary School exam, just like the college entrance examination that you will not take the carpenter job or agricultural knowledge, even if they are very useful.

"But in many cases, it is still very useful to master some basic knowledge of alchemy. Today we have learned, and you may have guessed about the tools and materials I have prepared."

There is a small crucible in front of each student seat in the staircase classroom. Below the crucible is a small magic furnace, and next to it are balance weights, measuring cups, cutting boards, potion knifes, long-handled spoons, and many strange-shaped animal and plant materials. Obviously, this is the device and material for making magic potions.

"Well, I originally thought it would be a group of two people, but now everyone can make do with four people first." Because the number of people poured in, there was a clear lack of potion making tools and materials that were originally prepared.

These things were purchased by Xiwei recently for the teachers and staff to go out for purchasing agents. Although the unit price is not expensive, it is not a small amount in total. If it weren't for free for food in the college, Xiwei might have to make a living by drinking the northwest.

"When you go out and take risks, it is easy to encounter monsters with special attack effects. The most common ones include "highly poisonous", "hypnosis", "paresis", "burn", "freezing" and "petification". What we are going to talk about today is how to make magic potions to deal with the special state of "petification".

Xiwei waved his finger and a picture appeared on the blackboard behind him. On it, six villains were drawn in simple strokes. The first one turned green all over and there were green bubbles on his head, which meant poisoning; the second one lowered his head, and the words "zzz" appeared on it, which was obviously asleep; the third one appeared around the body of the villain, which meant paralysis; the fourth and fifth villain's bodies turned red and blue, one had fire on its head and the other had frozen; the last one turned brown, and the edges and corners appeared on its body, which meant petrification.

With Xiwei's explanation, the first five villains disappeared, leaving only the last one.

"As we all know, petrochemical is a very troublesome state. Although it also has magical or spell-like abilities such as 'rock skin' that use local petrochemicals to enhance its physical defense, in most cases it will make you unable to move and become the enemy's bait." Xiwei waved his finger again, and a huge cat animal appeared beside the little man in the picture, and then tore the villain who was in the escape position but could not move into pieces.

"The only way to eliminate petrification is to use magic potions, except for the corresponding level of 'earth element stripping' and the 'evil curse dispersion' that can only be mastered by clergy."

Because of the illustrations, Xiwei's words not only became easy to understand, but also corresponded to the not-so-good-painted images, and even the somewhat funny images made the students feel very interesting and couldn't help but listen carefully... "Then the question is, does anyone know what the main material of 'relieving petrochemical agent' is?" Xiwei asked everyone.

Unless you have read books on potions, it is still a bit difficult to answer this kind of knowledge at once. Even if the material is placed in front of them, they cannot name it.

Although several second and third-year students have also taught themselves some alchemy to pass the written test and have some impression of this issue, it is already great that they are not busy hiding themselves, so they will not have the intention to be the first to be...

In the end, there were only a few people, including Alisa and Sophia.

Xiwei ordered one of them casually.

"Is it Mandela, Professor?" the student who was clicked to answer asked with some anxiety.

"The answer was very good, Ganesh a point." Sivi sent him a satisfied expression, and then sat down with joy on his face: "Mandela grass, also called Fengqian, is called doll root because its roots are somewhat like out-of-shaped babies. It is the main material for removing petrochemicals. In addition, Miss Visis, please do not poke their navels, the grass has dignity...even if they have been dried."

The girl named by Siwei stuck out her tongue and shrank her hands back with red faces amid the students' kind laughter.

"Then, the formula for the potion is here." Xiwei waved his finger again. The previous image disappeared, and was replaced by a huge piece of paper with large letters written on it with the amount of materials needed to prepare a standard bottle and the detailed steps for formulating: "Then, let's do it now. After the preparation is completed, I will give some rewards to the top team according to the results, and please work hard."

After saying that, he no longer cared about the students who were busy, took out the goblin duel invitation box on his own, adjusted the level to 5, and then opened it.

What appeared was an ocean goblin.

Xiwei glanced at it, raised her eyebrows with some dissatisfaction, and then directly shot a ten-fold magic missile to kill the other party in seconds.

His actions surprised many of them not yet their turn to help with the pharmaceutical production, so the more leisurely students were surprised.

The first-grade students didn't know what was going on. The ocean goblin was killed instantly. The second-grade students could barely guess that Siwei was using a magic missile, but they were still amazed at his casting speed. The third-grade students who had already passed the academy promotion practice saw more: just now, it was a spell-free casting and it was instantly, and the standard-powered magic missile was impossible to defeat the ocean goblin at level 5. In other words, this professor, who is not much older than them, can actually have an improved version of the magic that is more powerful than the spell-free instantly. Think about it, even the standard-powered magic has to sing for a few seconds. How big is the difference...

Although I knew before that the professors were incomparable to them, when even this new, obviously ten-year-old professor had such strong strength, they couldn't help but sigh that they were convinced by this professor who was not much older than them.

In the amazement of the students, Siwei finally killed the two flame goblins and a frost goblins that opened the box (...) with lightning speed, and finally a big goblin appeared.

This guy with rocky skin is used to test whether the medicine is effective for students. Then he began to walk in the aisle of the stairs classroom for a while, correcting some common and obvious mistakes for students.

Then a group of people began to prepare... Although for some reason, the original blue depeptide chemical agent in their hands turned purple, considering that the test items were not humans anyway, Svi ordered the earthly goblin to take a sip of purple liquid without any psychological burden.

About three seconds later, the Earth Goblin kicked his legs and foamed at the mouth and died. The body turned into a burst of white smoke and disappeared...

Xiwei looked at the students who were stunned when they saw this scene, and then carefully put a "super poisonous" label on the outside of the potion bottle they made and put it in the bronze storage box.

Even the monsters with level 5 can be killed in one go, and it is a monster with extremely adaptable ability like Goblins. The poison they accidentally created may be used when...

After that, Sivi opened the box three times before getting a new earth goblin.

This one had much luck than its predecessor. Although it was filled with potions by the remaining twenty groups that had completed the task one after another, it was not poisonous.

Finally, because of its hard work and great contribution, Xiwei did not kill it, but tried his best to control it and gave it lightly, causing it to fall into a coma and cancel the summoning.

Finally, among the nearly thirty portions of the potion recovered, including the group Alisha and others, there were five portions in total, which were very effective, almost immediately. The effects of more than ten portions were generally extremely weak or ineffective. Uh, there was also a highly poisonous portion...

After adding two points to the members of the five groups, Xiwei summarized the content and some precautions in the class, then ignored the students' unsatisfactory expressions, asked them to pack up their desks and announce the get out of class to be over.

The potion with very good results can be sold to the pharmacy store, and the potion with average results can be sold at a recycling price of more than 100%; you should know that this potion is very out of stock for the mercenaries. In this way, not only does the cost of purchasing textbooks come back, but Xiwei also made a small profit.

Not only that, the task of "becoming the most popular teacher in the college" during lunch break also showed a completed state.

The two-star mission is worthy of being two-star. Looking at the reward items that you usually have to accumulate for a long time to get when you fight, Xiwei couldn't help but smile like a conspiracy...!~!
Chapter completed!
