Soon, they arrived at the underground laboratory of the Jia family.

Jiayi spread out the prepared drawings and hung them on the wall. It's not the first time they've made sonar detectors, they're not new, they made a batch of sonar detectors to sell when their shop first opened. It's just that there is no time later, and there is no further production.

Several of them worked together, and Jiayi divided the entire sonar detector into several modules according to his own modular idea. He had thought of treating rune circles like programming before, treating each rune circle as a program. It's a pity that it failed in the end, and the runes are equivalent to the underlying machine language, which is really a bit weak for the current Jiayi.

However, Jiayi is not completely without harvest, modularity is one of the gains. Although modularization will make the rune circle less concise, it is easier to understand, just like the difference between classical Chinese and vernacular Chinese, the modular rune circle adds many descriptive runes, pays more attention to logic, and requires each module to be able to run separately, which is a complete function.

This will inevitably lead to the repetition of many runes, the original rune array, in order to simplify the runes and reduce the volume, are particularly streamlined, and many of the realized abilities share a circle circuit, which is concise, but it has higher requirements for production and higher requirements for learning qualifications.

Moreover, modularity can split the rune array, make each module first, and then combine them to achieve complete functions, which to a certain extent, can be regarded as reducing the difficulty of making rune arrays.

However, Jiayi is not that powerful at the moment, and can only split and modularize the apprentice-level circles, as well as modularize the construction of a limited number of mage-level circles, such as the sonar detection circle, and the greasy scroll circle.

Jiayi divided the sonar detection array into several parts, Yancy and Maduo made the main part, which involved energy storage and release, March and Jade made the display part, and displayed the received sound detection results into images, and Jiayi and Chester made the sending and receiving parts of sonar. The whole circle is divided into three parts, and each module is related to each other but independent of each other.

In order to speed up the production schedule, Jancy moved the magic furnace he bought from Maddo's house, his furnace is sold ready-made, more portable, unlike Jiayi's, the custom-made one is completely fixed in a corner of the laboratory, and you can't move it at all.

Two magic furnaces were opened at the same time, smelting the proportionally mixed alloys. Although it was already the month of Meng Chun (February), the climate was still very cold, but under the heat of the two magic furnaces, Jia Yi and them were indeed sweating profusely. The whole laboratory is not well ventilated, and it is almost like a big steamer.

If you don't want to lose money, then the metal formula for making the base of the rune circle is very important, unless there are any special advantages of the rest of the materials, otherwise most of the rune circles are made of metal as the base, because the metal is easy to smelt, you can easily change the formula, according to the actual requirements of the circle, you can make a more suitable base, reduce costs.

However, most of the elven items use wood as the base of the magic circle, because the elves are good at cultivating magic wood, and as long as the wood is not cut down entirely, it can still be regenerated. Although humans also have the technology to cultivate magic wood, they can't make the branches achieve the desired effect, and if they want to use it, they must use the trunk that has grown for a long time, and it loses its regenerative properties.

After successfully refining the base of a rune plate, March couldn't bear it anymore: "You go on, I'll go outside to breathe, it's too stuffy inside." ”

Although she hung a frost shield on her body, she felt even more uncomfortable, and one side was cold and a little hot, which was simply two heavens of ice and fire.

"Hold on a little longer. Jia Yi put down a piece of the made diaphragm, raised his head and wiped his sweat, "It's almost early, we'll go back in a while." If you can't stand it, let's sort them down first, and it should be better to stay away from the furnace. ”

Kaichi felt that he had miscalculated, but he thought that it would be more convenient to keep the furnace alive in the basement, but he didn't expect that the furnace would release such a lot of heat, and after being stopped in the basement, it would become so stuffy, which was completely different from being on the ground.

"After the sonar detector was done this time, the ventilation system had to be redone to channel all the heat to the outside. "Jiayi himself can't stand it anymore.

I didn't notice it, but I didn't have a furnace that was open for such a long time at once, so I felt a little hot, but it was fine after a while.

When March heard Jia Yi say this, he immediately stayed away from the furnace and began to count the rune substrates that everyone had made, but now it was actually just smelting the materials, and the shape had to be trimmed later, as well as the most important carving runes, and finally, the finished modules were assembled to make a complete sonar detector.

Seeing that March had counted all the smelted materials, Jancy asked, "How much have we made now?"

"20 sets, Jiayi's diaphragm is more, there are 30 sets, the speed is really fast. March said.

"Let's do this today, that's enough to make it for a while. Although we have a large number of diaphragms, we still have to forge them, and there is still work. ”

These diaphragms are used to produce and receive sound, and while the use of the circle alone can already achieve the effect, adding the diaphragm can give better results. Jiayi's own sonar detector uses the eardrum of the big-eared demon bat as a diaphragm, so the effect is the best. The diaphragm that Jia Yi is now smelting is simulating the effect of the eardrum of the big-eared demon bat.

However, the rigidity of the simple smelted diaphragm is not enough, and it has to be forged to meet the requirements of use.

The rest of the people quickly finished the work at hand, and everyone was not light, but they all endured it, and they were not willing to be the first to complain, only March had fewer scruples and less endurance.

Although Jiayi's house can accommodate all of them, they must go back to the college dormitory and cannot live outside.

Back at the dormitory, the roommates were curious about what Jia Yi was doing, and Jia Yi said, "I heard from the teacher that the lake will be cleaned up soon, and all of us are going to buy some equipment for safety." ”

"Will it be dangerous?" said Trudy, as if to embolden himself.

"Probably not, but at least make sure you can make it to the rescue of the teachers. Jia Yi shook his head slowly, and there was some hesitation in his speech, not that he felt that it would be dangerous, but that he felt that he was too full of words if he didn't change his words, and if something really happened, he would be guilty.

Just like an Internet company, write a long and large section of user agreements, all the responsibility is put on the user, if you look at these agreements carefully, compared to the deed of sale are much more hateful, whether Chinese or foreign, although the company itself does not want to have accidents, but will never leave the risk to themselves.

Trudy nodded: "Then let's go buy some equipment too, have you both bought it?"

He asked Jiayi and Yanxi in the last sentence, and after receiving an affirmative answer, he asked Jill and said, "Then Jill will you go with you?"

Jill sat on the bed and said lightly: "I don't need it, before I came to the academy, I brought a lot of talismans, but I didn't use them, these are enough." ”

"Oh well. Trudy spread out on the bed, "Jiayi, what kind of equipment did you buy?" ”

"It's best to buy one that can breathe underwater, after all, on a boat, overboard is the most common. For the rest, you just look at the purchase, and the shield is best to transfer the attack or transfer your own, don't resist hard, just hold on until the teacher comes. Jia Yi suggested.

Trudy nodded, agreed, asked Jia Yi and them to bring him breakfast, he was going to buy equipment early the next morning, so as not to get too many people behind him and not be able to buy good equipment.
