After the blast furnace was completed, the steelmaking furnace that Jiayi was about to put on the horse stopped, the time cost was not enough, and Jiayi didn't want to be in place at one time, and slowly upgraded, which was more in line with business logic, of course, the most important thing was that Jiayi was lazy.

Because the construction of the blast furnace has been completed, Jasber has already gone back first, he is an auditor, unlike the rest of the people who have not yet entered the school, and the auditor is not like a regular student, and he can leave at any time. Auditors spend a lot of money, and if they have any tasks that pay well, or if they find any relics, they will go out on a temporary mission and continue to study when they go back. No one cares if you can keep up with the progress or not, it all depends on your self-awareness.

The other four didn't go back with them, because it wasn't time for the school year to start, so they were going to follow Jia Yi for a while and go to the academy together.

After the wooden track connecting the mine and the smelter was repaired, the blast furnace was officially activated, and at this time, Kaichi finally knew what felt wrong - the ore production was not enough. Although the blast furnace is efficient, it is impossible to smelt two parts of iron from one ore, so the progress of mining ore cannot keep up, resulting in the blast furnace being forced to stop after not firing for a long time.

Eunice told Kaichi about this matter, but Kaichi had no choice but to invent a mining machine. Although Jia Yi occasionally has this idea, but after thinking about it, the requirements required for mining are much more troublesome than making a car, if you lie down in the mine, you will be blind, and you have to leave a mage here to maintain it, and the gains outweigh the losses.

In the end, Jiayi could only let them use more alchemy potions for mining ore, or purchased ore. Because of the cost gap, even if the ore is purchased at a higher price, the cost of smelting iron is lower than that of the rest of the chamber of commerce.

After all, blast furnace ironmaking is still the first time, and everyone is not familiar with it enough, including Jiayi, so many things are encountered for the first time, and they need to be slowly groped and run-in. But none of this is about Kaichi now, and he and Chester and the four of them are going to team up together and travel through the wilderness to reach the academy without taking an airship.

It's not why, it's just because I'm in a hurry, just like someone riding the Sichuan-Tibet line. After the blast furnace was built, there was nothing to do, so I just went to the academy in advance to familiarize myself with the environment.

"Jiayi, is this the detection circle in your paper, how much does it cost? I'll buy one too. Marche was visiting the Chamber of Commerce, and when he saw the detection array designed by Jiayi, he asked curiously.

Although they decided to go to the academy by land, they had not yet set off, so they would rest for two days and take a stroll in the imperial capital. They weren't going to the academy from the imperial capital, so it was the first time they had come to Memphelbo.

Jiayi said: "This array disk is for ordinary people, because of the addition of energy storage modules, as well as activation modules, so the effect will be worse." It's better to make one yourself, it's not too complicated anyway. ”

Jiayi's detection array disk was handed over to the Chamber of Commerce, and after optimization, the design was finalized, and now the initial version has been released, although it has not been officially released, but it is not far away. Because Jiayi's strength is still low after all, although the sonic detection array designed is exquisite, it is actually not very difficult, as long as a formal mage with a little level can make one by himself. Therefore, when Jia Yi and the others made the commercial detection array, they did not target the mage group, but more for the mage apprentices and the adventure team without mages.

"It's too troublesome to do it yourself, and besides, has the spell model of your circle been designed successfully? ”

"Not yet, but soon. Jia Yi felt a little embarrassed, it had been two or three months since the probe array was made, but his spell model had not yet been completed, and the efficiency was really low.

"I've been busy with blast furnaces lately, so the progress is a bit slow, and it's almost enough to have another five or six days. However, due to my strength, you know, the effect is not particularly good. ”

Although Jiayi has improved the structure of the detection array according to the structure of the big-eared demon bat, and the spell model designed now has also been modified, but after all, it is not as good as the original, so whether it is the array disk that is being sold or the spell that will be completed, the effect is not as good as the array disk in Jiayi's hand. Also, now the array disk has an official name, called a sonar detector.

"I thought you'd always call it a probe array, but your name is really not good, sonar is a word you made up yourself, combining sound and movement. Is the name of your spell determined? Isn't it also called sonar detection?" asked Jade as he heard the name of the sonar be said by Kaichi.

"No, I'm going to call it the bat ear, I originally wanted to call it the bat ear of Kaichi, but it feels some, some too high-profile, after all, there is no nobody who leaves a name on the spell, I don't know if it will be accepted if I name it like this. Jia Yi said this, but in fact, he brought it up in the hope that he could be named after himself.

In fact, the name is as you wish, for example, if you swing out a palm, you have to call the eighteen palms of the dragon is not okay, but others don't admit it.

He was a little worried about whether it would be bad to name himself and whether people would accept it, after all, in his impression, all the mages who named spells with their own names as prefixes were not nameless, and the purple-robed mages were almost the lowest.

"You're stupid. Chester became excited, "Why don't you take advantage of this opportunity, I wish I could name a spell after myself, but unfortunately I don't have this opportunity." ”

"Hahaha..."Chester had just finished speaking, and suddenly March and the others all laughed, and the laughing Kaichi was a little overwhelmed, and Chester was full of black lines.

Kaichi looked at the laughing March and asked, "What's wrong? Why are you laughing like this all of a sudden?"

Chester said helplessly: "I also wanted to name a spell after myself, and then changed the fireball technique to rocket technique, and wanted to name it Chester's rocket technique, but it was rejected. As a mage, isn't it normal to want to name a spell after yourself, to laugh like this. ”

Jia Yi couldn't detect where this joke was, although it wasn't recognized, but at least his courage was commendable.

"You, you don't know, he, what his rocket skills are all about. March's words were intermittent, and he gasped for several breaths before continuing, "His rocket tree is actually a fireball technique, but the shape of the fireball technique has been changed into the shape of an arrow, and the rest of the effects and spell structures are almost identical, how can it be recognized." ”

"Was it young and ignorant at that time? Chester muttered and quickly changed the subject, "But Kaichi, I don't think it's a problem for you to name it after yourself, this is a new spell of yours, and it will definitely be recognized by the wizarding world if it is not scribbled or changed on the original spell as a new spell." ”

Ma Duo, who had not spoken out on the side, also said: "As for you who feel that your magic level is relatively low, you don't have to worry at all, although the popular spells now are all handed down by very powerful mages, but there are also a lot of new spells passed every year, but the spread is not large." If you can't become a legend, then your spell will be drowned in the vast sea of spells, and if you become a legend, then your spell will definitely be known to the public. ”

Jia Yi was convinced, in fact, his heart originally wanted to be named after himself, he just wanted some encouragement from the rest of the people to give him more confidence, if March they felt that Jia Yi was not good to name after himself, Jia Yi would also name after himself.

After all, it's a big honor, like a textbook with a theorem named after you.
