In front of the rest of the group, Kaichi began to transform the skateboard.

"This single nozzle is not good, the requirements for handling are too high, it is not conducive to adjusting the attitude, so we changed to multiple nozzles. As soon as he spoke, he took out a charcoal pen and drew a diagram on the metal plate.

He turned the original single spout at the tail into a combination of one large and four small multiple spouts: "Like this, use one large and four small, forget it, it's still one large and two small." ”

As he spoke, he erased the original diagram and changed it to a large and two small side by side, which made it easier to make, save costs, and leave room for the later launch of the updated version, Jiayi is becoming more and more of a profiteer.

In this case, the nozzle in the middle is mainly to output power, and the nozzles on both sides are used to adjust the attitude, so that it is easy to ensure balance. ”

That being said, even adjusting the attitude is not so simple, and it is not easier to adjust the attitude with a few more vents, and there is also an algorithm problem here.

Then, he drew a schematic diagram of a magic gyroscope on the head of the metal plate, and said: "This gyroscope is the most important thing, without this, we can't detect the posture of the skateboard at all, and everything that turns is controlled by the cushion foot, but now there is no need for foot assistance, and without the gyroscope, it is impossible to determine which way the person on the skateboard is going to deflecrate." ”

This thing is like a balance bike, relying on a gyroscope to maintain stability and detect changes in the center of gravity of the person on it, and then adjust the attitude according to the center of gravity.

In fact, if there is no gyroscope, if someone has a good grasp of the center of gravity, they can also adjust it themselves, but this is a bit too demanding for the user.

The person who can use the kind of magic jet skateboard that doesn't have the aid of a gyroscope is less likely to be a mage, more likely to be an assassin, and has too much of a balance to grasp.

Jiayi just drew a schematic diagram, and the specific method actually has to be realized slowly, but just a schematic diagram has already given Yangxi and them a direction.

It's not a modern fable that says that the one who knows where the circle is is valuable, and the circle itself is not valuable.

Since it has already begun, Jiayi and the others will not delay any longer, and will directly start to act, leaving Jiayi's puppet aside first, and then designing the layout of the magic array on the skateboard.

As for the puppet, it was originally to verify what Kaichi himself had learned, but now it has come to an end and is no longer important.

Although classes are usually required, with Jiayi taking the lead, everyone is still moving quickly, and when February is about to end, the latest skateboard magic design plan comes out.

Jia Yi actually took fewer classes at this time than in the first grade, and spent more time in the laboratory.

First, because his foundation is already very solid, and the first semester is more to familiarize himself with the life of the academy, and secondly, Orlando has become a purple-robed mage, and most professors will give Orlando some face.

So Jia Yi spends most of his time in the lab, and when he has time, he goes to the classroom to listen to a few lectures, and then listens to Marge's experience in class, and sees if the professor has any useful experience to impart. If there is a problem, then go directly to the professor for advice, and in general, no professor will refuse.

Even Professor Terry, who doesn't deal well with Orlando, rarely refuses Kaichi's request, at most his tone is not very friendly.

In fact, Jiayi is also a routine operation, even without Orlando, the academy will rarely have restrictions on "genius" students like Jiayi, because their progress is too fast, and it is impossible for the academy to pull the progress down to the same level as them, which is simply a disaster for ordinary students.

Therefore, for students who can study in advance, the professors are happy to see it, but Jiayi's progress is a little too fast, so fast that the calculus professors want him to substitute for the class.

It's just that although the design plan has been designed, Jia Yi doesn't have time to realize it immediately, because it is time to start the seedling raising of elf rice.

......

......

This day happened to be a rest day, and Jia Yi and his friends came to the greenhouse of the laboratory, and the surging smell inside had almost disappeared, leaving only some slight smells, which would no longer make people feel unacceptable.

However, March was still a little unaccustomed to the smell here, and said complainingly: "Anyway, we don't need to do it, what are you pulling us over for, let me rest at home for a while." ”

Recently, I've been busy verifying the design of a jet skateboard, and I haven't slept well.

Kaichi said, "Is this for your good?" Although now because of the agreement with the academy, it cannot be opened to you, but when you graduate, you can learn to grow elven rice by yourself, and the academy has reached a consensus to control the spread of elven rice, and you can plant elven rice at that time, whether it is for personal use or small-scale sale, it is very good. And you're more familiar with this, so of course I'm going to pull you over to help. ”

As they spoke, they came to the vicinity of the laboratory in the greenhouse, where they met Terry and the others, who were standing there.

Terry stood in the middle, next to several professors, including Orlando and Queenie, who were all there, perhaps to come over to support the Kaichi platform.

A few professors are in the middle, and there are a group of students outside, all of whom look young, but there are also a few people who look old-looking, not like the teachers and students of the academy, he has no impression of them at all, maybe they were recruited by the academy from outside, or some legendary "secret guard" or something, and I don't know if there is such an institution as an academy.

When Terry saw Jiayi coming, he said with some displeasure, "Why did you come so late? Next time, be on time, everyone's time is precious." ”

Jia Yi looked at the sun, this is you came too early, before he came, he looked at the bell tower of the academy, the time was completely in time, but Jia Yi did not refute, lest everyone quarrel, it was completely unreasonable for Terry, but if it really quarreled, Jia Yi would definitely have to bear part of the responsibility, and in the end it would only be Jia Yi who suffered.

Orlando, who was next to him, saw Terry reprimanding his student, but only stared at him a few times, but did not speak, and laughed.

He knew that Terry could only say two words with his mouth, and even if he didn't like Kaichi, he could only say two words, and he couldn't do anything substantial.

Seeing that everyone had arrived, Terry didn't continue to dwell on whether he was late or not, pointed out the people behind him, and said: "These are the people who signed an agreement with the academy, and they will not reveal the cultivation method of elf rice, and the next time is to learn from you, and Moore will follow, you can find him if you have any questions." ”

He didn't mean to introduce these people one by one, maybe he also had the intention of asking Jiayi and them not to know each other. Originally, it was most appropriate to arrange Gwen to follow, she knew the most about plants, and she could understand better by learning the cultivation method of elf rice.

However, Gwen was still busy with plant taxonomy, and there was no time at all, and many of her classes were now taught by March.

Moore came up to greet Jia Yi and said, "Gwen is busy sorting plants, you know, the academy's elf rice matter has been assigned to me, what needs to be done, just tell these people, if there are more things for them to do, they can learn faster." ”

As he spoke, he walked up to Jiayi's side, wrapped his voice with magic power, and transmitted it to Jiayi's ears: "Don't teach all of them at once when you teach, remember to divide them into groups, don't let them learn everything in each group, don't let them learn it all." ”

The effect of the agreement between the mages is still very good, especially since one of them is still a behemoth like the Academy, even if it teaches them, they can't and dare not leak it. However, the necessary precautions are still necessary, so as not to have any accidents.

Jia nodded: "I will pay attention, some key measures are only handed over to the academy, and these people will not have them in their hands." ”

Moore nodded, moving out of the way and motioning for Ga's start.

In fact, today is just sowing seeds, the thing is very simple, the reason why so many people came, more, is for a sense of ceremony, something similar to the opening ceremony, and later, except for Moore, it is estimated that no other professors will come over and stare at it every time.
