28. The first alchemy

　　The afternoon class was an alchemy experiment class. Frandy and Gustav came to the big laboratory early.

　　There are only thirty students studying in the laboratory of the middle school. But the area is very large, and each student has a large laboratory bench.

　　The experimental bench was filled with various instruments, tools, and some precious materials. When Frandy and Gustav arrived at the large laboratory, the teacher who taught the alchemy course had not come yet, but the students had already come. Not a lot. Everyone is preparing on their own laboratory benches for the needs of the afternoon class.

　　"Hi, Katrina, you're so early." Frandy greeted Katrina in the front row.

　　This little girl has loved studying since Psal Island. Until now, his academic performance in alchemy is also at the forefront of the class.

　　Busy Katrina said: "Frendi, Gustav, you guys are a little late today. Get ready!"

　　"Okay!"

　　Frandy and Gustav's experimental bench was next to each other. After the two arrived at the experimental bench, they began to process the materials.

　　To become an alchemist, the two most important and commonly used materials are fine gold and secret silver. Adamantine has the best performance for transmitting magic essentia, and there will be no loss in the process of transmission, but the price of this material is also the most expensive. Much more expensive than ordinary gold.

　　Miyin, on the other hand, is able to transmit spiritual power, allowing the alchemy products made to be controlled and used by the user. Of course, this material is not much cheaper than fine gold.

　　What Frandy is preparing now is to wire-draw fine gold and dense silver. This is the basic skill of alchemists. Because these two materials are expensive, in the process of alchemy, the least amount must be used to maximize the effect.

　　And some advanced magic needs to make very complicated circuits. Only by making fine gold and dense silver can they be highly concentrated together to reduce the area.

　　Otherwise, a dagger engraved with "swift magic" will only be bulging because the fine gold and mithril are not pulled thin enough, but it will be spurned by all alchemists.

　　The job of drawing wire is not difficult at first. The hard part is the final filament, pulling a standard adamantine or dense silver rod through a small hole in a piece of steel that is only a tad smaller than a standard rod, and these two metals are the softest of all metals Yes, and the ductility is very good. After stretching through a smaller hole, a wire that is thinner than a hair will be obtained.

　　This kind of wire is engraved in various vehicles according to the design drawing of the magic circle, and it will form a magical magic crop.

　　Both Frandy and Gustav were concentrating on the task of pulling the thread. In fact, this kind of work does not need a noble alchemist to do it himself, because it is just a simple effort, and a person who is careful enough can do it. There are special thread-pullers that are even finer than these students.

　　However, this is the foundation of an alchemist, and it is something that an alchemist must master, not to mention pulling strings. When he first started learning alchemy, Frandy even took a big hammer and learned to forge for a while.

　　And when the alchemy reaches a high level, the required thread will be so thin that it cannot even be observed by the eyes. That is not what the thread puller can achieve, but requires the alchemist to control it with his own mental power, so the mental power The training of alchemists is also extremely important.

　　Of course, the students in the middle school can only be regarded as apprentices, and they don't need to be so meticulous.

　　It didn't take long for an alchemist who was in charge of teaching the alchemy experiment course to wear a special lab coat and walked into the big laboratory.

　　The alchemist's work clothes are very simple. It is a white coat. The main purpose is to prevent harmful substances from splashing on the body. It can be found at the first time and then taken off immediately. However, students in the middle school are not exposed to those harmful substances, so there is no mandatory requirement to replace them.

　　"Classmates, class starts now."

　　The students who were busy on the experimental bench stopped moving and looked at Teacher Feodor Santini in front of the teaching desk.

　　"Have you all completed the magic crystal task I assigned a few days ago?" Teacher Santini asked the students.

　　Many students answered: "It's done", only a few of them shook their heads in shame, indicating that they were not done.

　　Seeing that most of the students have finished, Mr. Santini nodded with satisfaction and continued: "Then, since most of the students have already obtained the crystals, we will continue with the following courses, those who did not get the crystals. People, you can watch the operations of the students who have already obtained them."

　　So the classmates who already owned them took out the magic crystals they carried and put them on the experimental bench, ready to start the operation.

　　The magic crystal is a kind of crystal obtained from a natural mineral after some magic treatment. This crystal has a great feature, that is, it can be placed in magic seeds and cultivated.

　　Low-level magic crystals are easy to get, and you can buy one with only a few hundred gold coins. Of course, it is easy to exclude civilians. A few hundred gold coins are enough for a family of civilians to live a prosperous life for more than ten years.

　　But in the eyes of those great nobles, it is already very cheap, and things that can be bought with gold coins are not considered precious.

　　However, high-level magic crystals belong to the national strategic resources, and can no longer be measured by gold coins. Even if the nobles want one, it is extremely difficult to obtain.

　　The low-level magic crystal can place a small number of magic seeds, and the magic seeds are not strong enough. Forcing a powerful magic seed into the low-level magic crystal will cause the crystal to shatter directly.

　　Oskaya Imperial University has a lot of money, and every beginner alchemist will issue a low-level magic crystal. However, the magic seeds that need to be placed in the crystal require the students to find a way to find a magician for help.

　　What Frandy wants to make is a two-handed great sword that can be supplemented with flames, so his magic crystal needs to be filled with fire-type magic seeds.

　　But whether it's her sister Annie, Vito or Lilia, maybe because they grew up on Psal Island, the three of them are all practicing water-attribute magic. But Shirley is practicing wind attribute. This made Frandy waste his best efforts to get a senior brother of Vito, and put 64 fire-attribute magic seeds in the magic crystal. It cost a lot of money.

　　Of course, the magic seeds that can be placed in low-level magic crystals are relatively weak.

　　As for the magic seeds of his body demon, Frandy was reluctant to put them in. There were less than 100 magic seeds condensed in the past four years. Each takes a long time to condense.

　　The sword embryo of the two-handed great sword, Frandy, has already been made. It is made of excellent Terra steel. The weapons made of this steel are extremely sharp, even in the army. The material is this steel.

　　Under the guidance of Mr. Santini, Frandy began to make the first magic weapon in his life!

　　To make a weapon or other equipment that can release magic, you must first plan the direction of the fine gold and dense silver lines, the position of the magic circle, the inlaid position of the magic crystal, and finally leave the most convenient disassembly. Place to house the source of magical power - essentia ampoules.

　　Frandy has already considered all these things. The route direction has been drawn with a pen on the sword body. The magic crystal is inlaid at the connection between the hilt and the sword body. The upper part of the hilt is to engrave a magic circle inside, and the lower part is hollow to house the source quality ampoules.

　　I carefully applied the dark corrosive reagent along the drawn lines on the sword body. After waiting for about ten minutes, the lines coated with the reagent began to soften. Then I used the fine gold wire and dense silver wire that have been drawn to follow the lines. Lines are buried.

　　The Dark Corrosion Reagent was the item used by the great magician of Algernon to corrode Aunt Beth's long fangs on Psal Island.

　　This agent softens almost everything except glass. The effect is especially good on metal products. Therefore, it is also a common reagent for alchemists.

　　The sword embryo of the two-handed great sword had reserved the position of the magic crystal when it was forged. The rest is the most important thing is to carve the magic circle.

　　The engraving of the magic circle is very complicated, but the basic magic circle is relatively simple. Frandy has already memorized the pattern of the pattern, just engrave it according to the picture.

　　There are two ways to engrave the magic circle. One is to engrave the object of the same material first, then insert it like a magic crystal, and then connect the lines. The advantage of this method is that other magic circles can be replaced, so that the functions of magic products are no longer single.

　　Another method is to directly engrave the magic array at the reserved position. Although this method cannot be changed flexibly, it is very stable.

　　And Frandy chose the second option, directly marking the magic circle at the position left by the hilt of the great sword.

　　Since you want to carve the magic circle, you need to use a quartz carving knife. Quartz is an additive. When it exists alone, it is very fragile and will shatter when you pinch it. But when it is mixed with some metal, the strength of the metal is greatly increased, and the quartz carving knife is made of this mixed metal.

　　Another feature of quartz is that it blocks magic. As long as it is related to magic, whether it is source quality, element, or spiritual power, it has a good blocking effect.

　　First, apply a layer of dark corrosive reagent on the position, and then after Frandy and other positions softened, he picked up the engraving knife, held his breath, and devoted himself to engraving.

　　Just adding fire damage to the weapon, this is already the lowest-level magic circle, and it took Frandy about two hours to complete the engraving.
