The afternoon class was an alchemy lab class, and Frady and Gustav arrived at the big lab early.

There are only about 30 students studying in the Senior School laboratory. But the area is very large, and each student has a large laboratory table.

The laboratory table was full of instruments, tools, and some precious materials, and when Franky and Gustav arrived at the big lab, the teacher who taught the alchemy course had not yet arrived, but many of the students had already arrived. Everyone was preparing on their own laboratory tables for the afternoon lessons.

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

This little girl has loved to learn since Psalsal. Until now, his academic performance in alchemy is also at the top of the class.

Busy Katrina said, "Frandy, Gustav, you're a little late today." Hurry up and prepare!"

"Great!"

Franky and Gustav's bench was next to each other, and when they arrived at the bench, they began to work on the material.

To become an alchemist, the two most important and most commonly used materials are Adamantite Gold and Secret Silver. Adamantite is the best for transmitting Essence of Magic, with no loss during transmission, but it is also the most expensive. Much more expensive than regular gold.

Secret silver, on the other hand, can transmit spiritual power, and can allow the alchemy products made to be controlled and used by users. Of course, this material is not much cheaper than pure gold.

Now what Flandi is preparing is to draw the pure gold and secret silver, which is the basic skill of an alchemist, because these two materials are expensive, so in the process of alchemy, the least amount must be used to exert the maximum effect.

Moreover, some high-level magic needs to be made very complicated, and only by making pure gold and silver very fine can it be highly concentrated to reduce the area.

Otherwise, a dagger engraved with "Swift Magic" will be spurned by all alchemists because the adamantite and mythril are not drawn thin enough and bulge with a large bulge.

It's not hard to get started. The difficulty is the final filament, which pulls out a standard rod of pure gold or silver through a small hole in a piece of steel, which is only a little smaller than a standard rod, and these two metals are soft of all metals, and have good ductility, and after stretching through a small hole smaller than a hair, a wire thinner than a human hair is obtained.

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

Both Flendy and Gustav were concentrating on the task of pulling the strings, but this kind of work did not need to be done by a noble alchemist himself, because it was a simple effort, and someone who was careful enough could do it. There are specialized wire pullers who are even finer than the threads drawn by these students.

However, this is the foundation of an alchemist, and it must be mastered by an alchemist, not to mention pulling the thread, when he first started learning alchemy, Flandy even took a sledgehammer to learn forging for a while.

And when alchemy reaches a high level, the thread required will be extremely thin, and even the eyes cannot observe it, so it is not something that can be achieved by a wire puller, but requires the alchemist to control it with his own mental power, so the exercise of mental power is also extremely important for alchemists.

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

It didn't take long for an alchemist in charge of teaching the alchemy lab course to walk into the large laboratory wearing a special lab coat.

The alchemist's overalls are very simple, a white coat, the main thing is to prevent harmful substances from splashing on the body, which can be detected at the first time and then taken off immediately. However, the students in the Senior School are not yet exposed to the hazardous substances, so there is no mandatory requirement to replace them.

"Students, classes are now open. ”

The students who were busy on the laboratory table stopped their movements and looked at Mr. Fyodor Santini at the desk.

"Have you completed the task of the Demon Crystal I assigned a few days ago?" asked the students.

Many students replied, "It's done", and only a few students shook their heads in shame to say that they weren't done.

Seeing that most of the students had already completed, Teacher Santini nodded with satisfaction and continued: "So, since most of the students have already obtained the Demon Crystal, then we will continue with the following course, and the students who have not obtained the Demon Crystal can watch the operation of the students who have already obtained it. ”

So the students who already had it took out the magic crystals they were carrying, put them on the experimental table, and prepared to start operating.

The Magic Crystal is a kind of crystal obtained by some magic treatment of natural minerals, and this crystal has a great property, that is, it can be placed into magic seeds and nourished.

Low-grade Demonic Crystals are easy to obtain, and you can buy one for just a few hundred gold coins. Of course, this is easy but does not include civilians, a few hundred gold coins are enough for a large family of civilians to live in prosperity for more than ten years.

But in the eyes of those great nobles, it was already very cheap, and what could be bought with gold coins was not considered precious.

And the high-grade Demon Containment Crystal belongs to the national strategic resource, and it can no longer be measured by gold coins, even if the great nobles want a piece, it is extremely difficult to get it.

The number of magic seeds that can be placed in low-level magic crystals is small, and magic seeds are not yet powerful. Forcibly inserting a powerful magic seed into a low-level demonic crystal will cause the crystal to shatter directly.

Oskaia Imperial University has a lot of money, and every beginner in alchemy will be given a low-level magic crystal. However, the magic seeds that need to be placed in the crystal need to be found by the students to find a way to find a magician for help.

The finished product Flandi wanted to make was a two-handed greatsword that could supplement fire, so his magic crystal needed to be planted with fire-type magic seeds.

But whether it's her sister Annie, Vito, or Lilia, maybe because they grew up on the island of Pusal, the three of them are all practicing water-based magic. Shirley, on the other hand, practiced the wind attribute. This made Flandi waste his lot of effort 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 the low-level magic crystals are also relatively weak.

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

The sword embryo of the two-handed greatsword Flandy has already been built, and it is made of excellent Terra steel, and the weapons made of this steel are extremely sharp, even in the army, and many demon warriors are made of this kind of steel.

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

To make a weapon or other equipment that can unleash magic, you must first plan the direction of the Adamantite and Silver circuits, the location of the magic array carving, the location of the inlay crystal, and finally leave a place that is most convenient to disassemble to place the source of magic power, the essentia ampoule.

These Flandies have already thought about it thoroughly, and the route direction has been drawn with a pen on the body of the sword, and the magic crystal is inlaid at the junction between the hilt and the blade. The upper part of the hilt of the sword should be carved with a magic array inside, and the lower part should be hollow to place the essentia ampoule.

Carefully applied the dark corrosive reagent along the drawn lines of the sword, waited for about ten minutes, and the lines coated with the reagent began to soften, and then buried them along the lines with the pure gold and silver threads that had been drawn.

The Dark Corrosive Reagent is the object used by the Archmage of Algernon on the island of Psalar to corrupt Aunt Beth's long fangs.

This reagent is capable of softening almost everything except glass. It is especially effective for metal products. Therefore, it is also a common reagent for alchemists.

The sword embryo of the two-handed greatsword has already reserved the place of the magic crystal when it is forged, and it can be easily inlaid into it, and then connected with the lines of pure gold and dense silver. The most important thing left is to carve the magic circle.

The carving of the magic array is very complicated, but the primary magic array is relatively simple, and Flandy has long remembered the pattern of the formation diagram, just engrave it according to the diagram.

There are two ways to carve a magic circle, one is to carve an object of the same material first, and then inlay it like a magic crystal, and then connect the line. The advantage of this method is that it can be replaced with other magic arrays, so that the function of magic products is no longer single.

The other method is to directly carve the magic circle in the reserved position, although this method cannot be flexibly transformed, but the stability is very high.

And Flandi chose the second option, directly carving the magic array in the position left by the hilt of the big sword.

Since you want to carve the magic array, you need to use a quartz carving knife, quartz is an additive, it is very fragile when it exists alone, and it will shatter when pinched. But when you mix it with some metal, it makes the metal much stronger, and quartz knives are made from this mixed metal.

Quartz also has a property of blocking magic, as long as it is related to magic, whether it is essentia, elemental, or spiritual power, it has a good blocking effect.

First, a layer of dark corrosive reagent was applied to the position, and then after Flandy and the other positions softened, he picked up the carving knife and concentrated on engraving.

Just adding fire damage to the weapon, this is already the lowest level of magic array, and it took Flandi about two hours to complete the engraving.
