Early the next morning.

The "construction team" of the Skoll Chamber of Commerce arrived, led by a mage, and the rest were all Anzan men, with a storage box.

Kaichi took them to the underground laboratory, chose a corner, and began to build the magic furnace he needed. In fact, the basement is not the best place, because it is too stuffy, the heat can not be dissipated, it is best to be outside, ventilated on all sides, but then there is no safety guarantee, in case someone damages it, it is not good, and the studio is underground, every time you smelt something, you have to run around, it is not convenient.

However, fortunately, Jiayi's design is to avoid the heat leakage as much as possible, and to ensure the temperature in the furnace by reflecting the radiation of heat, so the heat dissipation is relatively small and will not appear too hot. Kaichi's stove is prepared to use coal as a source of heat, and magic as a supplement, which is more economical.

Originally, coke should be used for the best effect, but Jia Yi only built an iron-making blast furnace for his own chamber of commerce, and there was no expected steel-making furnace, let alone a coke oven, so he couldn't use coal to make coke by himself, so it was too troublesome, so he could only make do with coal first, plus magic assistance, accelerant or something, it was not much worse.

The newly built magic furnace is built using volcanic lava as a hearthstone, volcanic stone is a volcanic eruption, carried by magma, erupted from the ground, after lava and high temperature, very resistant to high temperatures, and after magma training, it has a good affinity for fire spells, it is a very high-quality refractory material, and it is the best to use to make furnaces, but it is slightly more expensive.

Jia Yi had already prepared the drawings the night before, he had designed the blacksmith furnace and the iron-making blast furnace, and he also had a lot of experience in the design of high-temperature furnaces, but this time, he changed the design a little to improve the use of heat. The furnace is divided into two layers, the innermost layer is made of volcanic stone, which is resistant to high temperatures.

Outside the volcanic stone, Jiayi arranged four metal plates, all of which were arranged with a layer of magic circles on the inner layer of these four metal plates, which could help raise the temperature in the furnace, and the outer layer was arranged with a thermal insulation circle, which could reflect the heat in the furnace, although it could not be 100% reflected, but it could also prevent most of the heat from diverging, but unfortunately Jiayi's spell level was still lacking and he couldn't do his best.

Inside the high-temperature resistant inner furnace, there is a bottom plate full of holes, under the bottom plate is the air outlet, which can blow in, and the bottom plate is depicted with a combustion array, which can improve the combustion degree of fuel.

The outermost layer is a protective layer, a thermal insulation layer, a heat absorbing layer, and a granite stone protective layer, which can make the external surface temperature of the furnace not too high, avoid burns, and protect the inner furnace from damage.

Jiayi's spell level is limited, although the design is very good, but the magic circle made does not have the desired effect, so he carved the magic circle on the metal plate, and each metal plate can be removed, and after the strength is higher in the future, you can upgrade the metal plate that depicts the magic circle, and the shell is left, just like upgrading the computer, upgrading the memory, CPU, and even the motherboard, but the hard disk main chassis and power supply can continue to be used.

Jiayi is also influenced by modern modularization, at this time people do not have any modularization and upgrading ideas, the things produced are almost one, even if it is the same commodity produced by two same chambers of commerce, the parts cannot be used together, because each product is made and trained separately.

At this point, Jiayi's Valoka Chamber of Commerce is much better, Jiayi popularized assembly lines and modularization for them, so Jiayi's Chamber of Commerce is more efficient, and the product parts produced can be universal, easy to maintain, and there can be a variety of accessories. This is also one of the reasons why the products of the Valoka Chamber of Commerce can be popular, other people's pens can only be like that, the pens of the Valoka Chamber of Commerce can be replaced, according to their own washing to choose different thicknesses, but also to replace different pen sets, more personalized, even if it is broken, changing the nib is much cheaper than changing the pen. At this time, pens are not cheap, and not everyone is willing to change pens because of a small problem.

Even rune pens can get different effects according to different accessories, which is of course more popular.

It took a lot of time to make the metal plate that depicted the circle, and due to secrecy, when the Skoll Chamber of Commerce left, Kaichi's metal plate plug-in only succeeded in making a plate for combustion at the bottom of the stove. When the "construction team" left, they were still very puzzled, the magic furnace that Jia Yi asked to build by himself did not have any magic, and the effect was not necessarily better than the magic furnace he bought, and the price was not cheap, except that the furnace capacity was larger, and there was nothing special. Only the mage who accompanied him seemed to see some mysteries, but he didn't ask too much, after all, it was also Jiayi's unique know-how.

The capacity of Jiayi's furnace is indeed much larger than that of ordinary magic furnaces, because ordinary magic refining furnaces have carrying requirements, so they can't be very large, while Jiayi's furnace doesn't need to be carried, so you don't have to think too much about the volume, and the surface area is larger when it is larger, and the requirements are lower when depicting the magic circle.

Because Jiayi's furnace burns fuel, Jiayi also opened up the basement and added a chimney, otherwise it would burn in a closed environment and have to be poisoned by carbon monoxide. The magic stove in the basement is ready, and Jia Yi also rebuilt a stove in the kitchen, the stove at this time is still relatively primitive, and even many people don't have a stove, just a fire with a clay pot on it, and the stove has to be a little worth someone to afford it.

Although there is also a stove in Jiayi's house, it is not to Jiayi's heart, and Jiayi redesigned the stove and turned it into a classic farmhouse earthen stove with two inner and outer pots combined, just like the one in his own home. If you have money, Kaichi wants to make a magic stove like a gas stove, but unfortunately, it is not only expensive to make, but also expensive to use for cooking fuel. Using magic to make a fire, the cost of one or two gold coins after a meal is always required, which makes Kaichi temporarily cut off the idea of using a magic stove to cook, which is too extravagant.

Jia Yi and Yang Xi are in the laboratory, studying the rune board that Jia Yi needs, one person is still too slow, and Yang Xi's magic array is at a good level, and he also made an auxiliary flying machine, although the effect is not very good, but it is also very good.

"Jiayi, both sides of your rune board have to depict rune arrays, and they will affect each other. Yang Xi looked at the rune array that had failed again and said to Jia Yi.

"Why don't you replace them with two rune boards, and that should be fine. Well... It is estimated that there will be problems when the two rune plates are glued together, interfering with each other, and a layer of shielding is needed in the middle. ”

Jia Yi shook his head: "It's too wide, the reserved gap is not enough, and using two rune plates is not as effective as one." ”

I thought too much about it when I was designing, and I didn't think about the question of whether it was suitable or not, but I didn't expect that it was stuck when designing the rune circle now. He used to design all of them in one piece, but this time he suddenly remembered that he wanted to make a plug-in, but he didn't expect some problems.

In fact, if you really want to solve it violently, it is not very difficult, either tear down the shell and rebuild, or directly use magic to cut the slit a little bigger. However, Kaichi didn't want to do this, he wanted to make a qualified rune board plug-in, which could be regarded as a test for himself. Although this thing is difficult, it can be solved by debugging it slowly.
