The blazing iron is first calcined by the furnace fire, and after it is fired into a liquid state, it is poured into a sand mold and poured to set the shape, and after the shape is set, it is taken out for forging.

First, a huge forging hammer is used to forge the entire iron bar into iron sheets, and then it is rounded, flattened, folded, and continued to be forged until after several times, the stress inside the entire iron bar becomes uniform, the texture is tight, and there are no cracks and gaps inside.

It took Jiayi more than half a day to forge his first sword under the guidance of a hydraulic hammer and two "senior craftsmen".

The body of this sword is forged in the style of an imitation of the eight-sided Han sword, but it is slightly wider and longer than the ordinary Han sword, and the length of the sword body is about one meter two, which is similar to the length of the ordinary long sword.

The eight-sided Han sword was originally a bronze sword, because the bronze hardness was not enough, the shape of the eight-sided sword spine was used to increase the strength of the sword body.

However, the knight's strength and defense are far superior to ordinary people, and the requirements for the firmness of the weapon are also higher.

At this time, the eight-sided Han sword is just suitable for knights, and the increased weight of the sword body increases the feel of the knight when using it, and the thickened sword spine makes the sword body stronger, so you don't have to worry about the risk of breaking the sword when fighting.

After the sword body was built, Kaichi waited for it to cool down a little, and then began to carve runes on the sword body and build rune circles, it is said that the most superb swordsmiths can use the forged lines to build natural rune arrays, but Kaichi has always expressed doubts - it is too difficult to master both forging and rune circles at the same time.

Those who are good at rune circles may not be able to afford forging, and those who are proficient in forging are likely to not know rune circles at all, and it is really difficult for some strong people to play patterns according to specific requirements.

Even if Jia Yi thought that he had some experience with the rune circle under the guidance of Orlando, he didn't think that he could practice it and make a pattern that conformed to the rune circle by forging it.

Jia Yi used a special diamond engraving pen to quickly carve runes on the sword body, the sword body has not cooled down at this time, and while carving the runes, he can also feel a hot feeling, feeling that the hair on the back of his hand is about to be roasted and curled.

After carving the rune, Kaichi quickly filled the prepared magic dust mixed with the materials made of Mithril Mountain Copper to quickly fill the carved rune, and then inlaid a flame lion's magic core in the uppermost part of the rune near the sword grid.

After everything was arranged, with the circulation of the magic power, the magic power inside the magic core flowed throughout the rune array, and the materials that had just been filled in the magic circle began to melt, and slowly penetrated into the inside of the sword body, leaving only a layer of shiny coating inside the rune pattern.

Then, Jiayi used a special solvent to quench the sword body that was basically completed, and after the quenching was completed, it was coated again to cover the rune circle that had just been carved on the sword, so that if there was no real contact, it would be impossible to find out what rune circle was depicted on it.

The sword body is made, and finally the sword grid is installed, the hilt of the sword, and a small piece protrudes downward from the middle of the sword grid, covering the magic core on the sword body. In this way, a long sword that looks dignified and stable, with a slightly wider back and narrower front, and does not look very prominent, is made.

At first glance, this sword is not much different from an ordinary sword except for its shape, but if you look closely, you can see that there is a red flash on the sword body from time to time, which is the effect of the magic power being fed back to the sword body after it is gathered.

Kaichi didn't open the sword for the time being, turned around and started to make another sword, this sword had not yet been cast, and Kaichi had already thought of the name - Frost Sorrow.

I just don't know if the sword that has been cast now should be called the joy of fire.

The sword cast in the back uses cold iron, which is more suitable for the rune circle of water and low temperature, so he will call this sword Frost Sorrow with bad taste.

Although some people believe that the solvent method should be used for the smelting of cold iron, so that the cold iron results are the best, but the latest research results suggest that the smelting method used for cold iron does not have much effect, as long as the final cold iron is obtained.

As for the belief that the quality of cold iron obtained by the solvent method is better, it is just an empirical awareness, just like people think that black wolfberries are more nutritious than ordinary wolfberries, and there is not much difference between the two.

Kaichi is very interested in cold iron, and after careful research, he finds that there is no magic of the water system in cold iron, but it is easier to accumulate water vapor.

In fact, there is no such thing as water magic.

Classical magic theory is built on the basis of the four elements of earth, water, fire and wind, but now, the classical magic theory has been greatly challenged, as people understand magic more and more, more and more feel that the hypothesis of the four elements has become outdated, and the world is more and more different from the cognition.

But the old model was destroyed, the new model was not established, the classical model has been on the verge of collapse, the new theory is the atomic hypothesis, but the atomic theory has not really stood up, gravity appeared, and then the electromagnetic force also appeared, along with the gravitational force and the electromagnetic force appeared the force field system spell and the electromagnetic system spell, these two can not be assumed by the atomic theory.

There were already flaws in atomic theory before it could really gain a foothold.

And even if the atom is not the smallest element, there should be a question mark, because there are too many atoms, and now there are hundreds of atoms found, and there is even a tendency to increase, which does not conform to the principle of simplicity, and the number is too much, which does not fit the mage's manipulation.

Tradition holds that Mithril and Silver are two different substances, with two different atoms as their basic components, but in fact the differences in nature between the two are not particularly different except for their magical affinity.

The theory of atoms is not even as concise as earth, water, fire and wind, even if the mage has a good memory, it is too troublesome to memorize the names and properties of hundreds of atoms, so the latest hypothesis is that there are smaller components inside the atoms, but no one has yet been able to give a conclusion.

Along with the electromagnetism, there is also the debate about the nature of light, whether light is a particle or a wave is also inconclusive, but as the electromagnetism edifice becomes more and more stable, the wave theory of light also prevails.

Along with the wave theory, it is the ether hypothesis, but the delay in making any discoveries in the ether also casts a shadow on the wave theory of light.

At this time, the four elements that had been struggling to survive had not completely disappeared, because the origin of magic was based on the four elements, and one of the most basic cognitions was that if the four elements were false, then how did magic be established in falsehood?

And in meditation, it is indeed possible to feel the nature of different magical elements.

At present, the understanding of the basic elements of the world is that the four elements hypothesis is still alive and well, and with the support of a group of old and young people, shouting that I can still save it; the atom says that it wants to be on top, but it is not perfect enough, and there are still big flaws, and it is not concise enough; on the other hand, about electromagnetism and gravity, you don't take us into account, where do you want to put us?

Actually, we can also stand in the C position, but how do gravitational and electromagnetic forces build the basis of matter? The mages don't even have an idea of this for the time being.

However, Kaichi knew that on earth, the understanding of the basis of matter is the four fundamental forces, electromagnetism, gravity, strong force and weak force.

But in fact, the conclusions reached on this earth, Kaichi can't guarantee that in this magical world, this point can still be applied.

It's just that when Jia Yi is meditating, he can still succeed by replacing his impression of earth, water, fire, and wind with the four basic forces, and the efficiency of meditation seems to be higher.

But magic can't be done by imagination, even though it seems like something made out of nothing.

He can only use this as a guide, but not as a guide.
