Early the next morning, Jia Yi found Bron and asked him to send someone outside the city to collect the body of the coachman who died yesterday, hoping that the night would pass and the body of the other party would still be there.

As for the attack yesterday, he took it lightly, only saying that someone had attacked, but he had escaped by himself, and he had already informed President Fogg, so he didn't have to worry about it later.

As for Kaichi's own injury, after taking the potion yesterday, there is no major problem, and the quality of Jiayi's physical strength and other aspects may not be as good as that of the knight, but the resistance to abnormal states is much stronger than that of the knight.

Yesterday he was embarrassed, but he didn't suffer any major damage.

After Bronn gave the order, he and Tina went to the courtyard outside Jiayimen, where Jiayi had been waiting for them for a long time.

When they arrived, Kaichi took out two long swords and threw them at each of them.

"This is the magic sword I built for you, and although it may not be as powerful as the weapons forged by the weapon masters, it is already quite powerful. ”

Kaichi walked up to Tina's side and raised Tina's hand with the weapon across his chest: "This sword, which I call Frost Sorrow, can be used to release the cold that erodes the opponent, making the opponent move slower and slower. It can also unleash Ice Blades as a complementary ranged attack, and finally release Frost Armor to protect yourself or target targets. ”

Then Jia Yi walked to Bron's side, Bronn also put the long sword across his chest when he saw this, and Jia Yi said: "This is the Lava Fury, an additional fire-based spell that can spit out a tongue of fire and attach it to the sword, which is very powerful. ”

In the end, Kaichi did not call this sword the joy of fire, but called it the wrath of lava, although the names of the two swords are not symmetrical after being translated into Chinese, but they can form CP in the lingua franca of the other world.

In addition to these magic additions, the two swords also added a sharp magic circle and a strong magic circle, which greatly improved the firmness, and also had the ability to avoid corrosion, in order to integrate all these magic circles, Jia Yi spent a lot of time designing the magic circle, and tried to use the modules in the magic circle as much as possible, before squeezing all these magic circles into the sword body.

However, this is not without drawbacks, because there are too many magic circles integrated, and the level of Jiayi is also limited, the effect of a single magic circle will be weakened a little, and there is no gathering magic circle, and energy can only be provided through the magic core.

However, relatively speaking, the magic weapons made by Jia Yi are already considered high-quality, and Jia Yi himself just says a good word can be regarded as a kind of modesty. It's hard to come across a better weapon made by Higaichi, and it's already a true masterpiece.

People who are good at Bijia Yi's forging process rarely have too strong magic array attainments, and people who are strong in Bijia Yi's rune array can rarely do it better than Jia Yi's weapon embryo forged with a hydraulic forging hammer. Combining the two, although Jiayi's weapon is not a master, it is also a boutique among the best.

The two swords attack and defend, it looks like a pair of swords, and the sense of CP is very strong.

Jiayi didn't stay long in Valoka, handed over the twin swords to Tina and Bron, and then went to Fogg's to thank him, and then packed his things and went back to the academy.

Originally, he was going to take a look at the newly selected factory of the Chamber of Commerce, and the machine tool he designed already had a preliminary prototype, and he was waiting for the site to be arranged here to be installed and generated - of course, he had to wait for Jiayi to complete the machine tool.

This attack still had some impact on him, and he now used up a large part of the props on his body, and if he met Durer again, it would not be so easy to escape, although he felt that Durer should not have the courage to guard himself outside the city.

......

Lying in the single room of the airship, Jiayi took out a piece of silver-white metal, which was a small piece of cold iron, and some leftovers left by Jiayi after making the magic sword were put away by Jiayi as his own reward.

Jia Yi didn't deduct the materials, this is really what is left after building a weapon, and the remaining materials are not enough to build a dagger, so Jia Yi put it away, speaking of which, he didn't charge for building weapons for Tina, but he just gained a little experience, and leaving only such a little material is really a conscience.

It is said that some blacksmiths always waste a lot of materials when customizing weapons, and then collect the leftovers and smelt them again, and you can get another material.

Kaichi is very interested in the cold iron in his hand, after the cold iron is forged into a weapon, it is more brittle than ordinary iron, and the toughness is slightly worse, so it must be combined with the rest of the metal.

However, this metal has a property that is completely different from the rest of the metals, and the tentacle cold is very effective at conducting spells in ice and water.

Kaichi originally thought that this was because of the different properties of cold iron, which caused it to be rich in water-based magic, but it was possible to smelt ore through smelting without damaging the performance of the ore, which made Kaichi feel very strange.

And when he examined it carefully, he found that this metal did not contain magic power, but only had excellent conduction properties for magic power.

At that time, his mind was all about weapon forging, and he didn't spend energy on research, but now that he was free on the airship, he took out this small piece of cold iron and studied it.

He conducted all kinds of experiments on the cold iron, although the conditions here were relatively simple, but the control of the spell to test the nature of the cold iron also allowed Kaichi to get a lot of results.

This cold iron has nothing to do with water or ice-based spells, and is essentially a temperature-sensitive metal. The cold iron automatically emits its internal temperature, just like the magnetic field of a magnet.

However, because the outside temperature will automatically enter the inside of the cold iron, the temperature of the cold iron will not become too cold, and will only remain in a relatively cold state compared to the surrounding area.

The low temperature is easy to accumulate water vapor, which makes the surface of the cold iron always look wet, perhaps because of this layer of water vapor, so that people who get the cold iron for the first time mistakenly think that the cold iron is friendly to water and ice spells, and there are water magic elements inside, even if someone finds out later that even if the use of fire to smelt still does not affect the performance of the cold iron, this concept has not been able to change.

And according to the current theory, there is actually no water magic element, only water spells.

After discovering this, Kaichi discovered that in fact, cold iron can not only support the spell circle of the water system, but also the spell circle of the fire type, because the essence of cold iron is the conduction of heat, not the conduction of water spells.

Kaichi used cold iron to make an iron ring with a simplified version of the scorching ray, and turned out an ordinary magic core and inlaid it.

He put on the ring, the size of his hand, and leaned back on the bed, he reached out and pointed at the base of the wall, and with a whoosh, shot a small hole in the plank.

He stood up in fright, and only reacted after releasing the spell, this was on the airship, if he damaged the airship, he was not sure if he could afford it.

Fortunately, I didn't hear anyone screaming, so I shouldn't have shot anyone.

He hurriedly removed the realization from the small hole and pretended to be nothing.

The ring made of cold iron is more effective and more powerful than the ring made of ordinary magic metal, and after checking this ring again, Kaichi determined that although cold iron is related to temperature, it is not limited to low temperatures.

This reminded him of the nature of temperature, which is the thermal motion of matter, and if the microscopic particles do not move, then they reach absolute zero. At this time, some people have already proposed a law similar to the law of conservation of energy, arguing that no spell can spontaneously generate energy out of thin air.

However, in terms of performance, the energy released by a single spell is much greater than the magic power consumed, so although this law of conservation of energy has been proposed and discussed a lot, it has not been recognized by a single person.

In order to explain the source of the extra energy generated by the spell, people have also proposed various models, such as the energy bar, and the source sea model, which is the source sea that the source sea feeds back, and many things that cannot be explained for the time being are hung on the source sea, but in fact, no one can really say what the source sea is.

At this time, Jia Yi began to combine the ice spells and fire spells he had learned, after all, both of them were related to temperature, and with the cold iron in his hand, he began to think about the temperature in the spell.
