"Teacher, is there anything more elastic and wearable?" asked his teacher after the morning class.

Now, they only attend classes in the morning and do their own experiments in the afternoon. After all, for a mage, it still takes a lot of practice to transform knowledge into strength. Sometimes, when Imu is not available, he still gives lessons to Dale and Flower.

He is now not only a student, but more like a teaching assistant, many problems need Yimu to give him a separate small stove, Flower and they have long been unable to keep up with his progress, but when Yimu is busy, as the price of opening a small stove, he needs to teach Dale and Flower.

"Is it for the car you've built now?" I've always wanted to ask you, why didn't you design a magic circle on it?" Imu asked.

Jia Yi was stunned for a moment by Yimu's question: "Teacher, you know, although I have learned several rune circles now, I don't have the ability to engrave them on artifacts, so I thought about making a car that doesn't use magic first." ”

The inscription of the rune circle on the bicycle is beyond the scope of Jia Yi's ability, and he is not unable to draw the rune circle now, but limited by the level of magic in the body, he can only draw some simple rune circles, such as making fire, cooling down, etc. For the application of basic elements, the size of the drawn circle cannot exceed one foot square, otherwise the magic power in the body will be unsustainable.

But apparently these circles are not used on bicycles, and you can't draw a flame circle on the wheels, and then ride up and emit fire, pretending to be Nezha?

At the very least, you have to engrave some magic circles that reduce wind resistance, weight, and even levitation.

The flying bike is his ultimate plan for his bike, but it has nothing to do with the present.

Imu frowned, not satisfied with Kaichi's explanation: "Although you are not enough to engrave a more advanced magic circle, you should have this awareness. You can print the circle as you see fit on your car so that you can add it later.

"Moreover, your own car can't carve the magic circle, so it doesn't mean that mine can't either?"

If it weren't for the last word, Kaichi would have been more grateful for Im's teachings. However, through Yimu's words, Kaichi also discovered his own problem, he still relied too much on the experience of his previous life, and he still didn't do a good job of combining with magic.

Of course, the main thing is the question of strength.

However, Imu is right to say that he should leave enough possibilities for his design to be modified, just as software design should leave for an extensible interface.

The last time I designed the fountain pen, there was no reserved place for the circle, but later Imu made a fountain pen that increased the size of the metal plate on the tip of the pen, so that there was more space for the place where the circle was inscribed. Last time he didn't realize it, this time he ignored it again.

Kaichi finally learned the lesson this time, after all, he is also a mage now, and he should think more in the way of a mage.

He forgot to ask his teacher if he had a rubber substitute, and hurriedly went back to his room to revise his design.

His first plan was to engrave the circle on the top of the bezel on the outside of the chain, increasing the width of the baffle and increasing the firmness of the body. But then I gave up, a baffle is just for aesthetics, the use is not much, if you ride to the wild and encounter weeds, it is very likely to get stuck in the main chain, and then you have to remove the baffle to deal with it, it is too troublesome.

So he removed the bezel again - he didn't design it in the first place.

Moreover, the baffle is not considered the main structure, if the circle is engraved on it, then it is likely to lead to uneven force, loosening, fracture and falling. In fact, according to this calculation, there is not much room for choice, in order to evenly withstand the force, the best place to engrave the circle is the frame.

Next, Kaichi changed the design of the frame, changing the original round tube to a wide oval shape. In this way, it is more appropriate to engrave the circle on it.

However, this still can't solve all the problems, because the general circle is flat, and if you want to engrave the circle on the tube, then the circle will have to be redesigned. Carving a circle on a round tube is not just a matter of drawing and rolling up the circle, because the operation of each magic force in the circle will affect each other.

When the magic is running, it creates a force field, just like a magnetic field is created when an electric current passes through it. If the two magic channels are too close together, they will interfere with each other, so the miniaturization and three-dimensionalization of the circle has always been a problem, not only in need of redesign, but also in the technical requirements of the inscriber.

Although Jia Yi didn't depict the strength of the magic circle, he also wanted to give it a try.

He first chose an anti-gravity circle - not to make the car fly, ordinary anti-gravity circles could not meet that requirement, just to reduce the weight of the car. After all, the theme of his car is steel, neither aluminum alloy nor carbon fiber, and its weight is too heavy, and it can be ridden more easily with an anti-gravity magic circle.

He has been trying to reconstruct rune circles using the idea of programming, hoping to be able to build magic circles and even magic as if they were programming. Although it didn't succeed, it gave him a different understanding of the magic circle.

And it's not that he doesn't gain anything at all, now, he can break down the circle, and divide it into different parts, just like the different modules of the program. In terms of programming, it is high aggregation and low coupling, and he is doing the work of decoupling.

However, although he can divide the circle now, he can't draw each module separately and combine it into a complete circle.

After splitting the circle, he still needs to draw all the parts at once to succeed, and after he splits it like this, although it is easier to understand, it leads to more strokes in the circle, and the difficulty of drawing increases.

To put it simply, it reduces the cost of learning and increases the cost of drawing. This is not advisable for the average mage, not only does the cost increase, but the easier understanding means that it is less difficult to crack - although the mage world has something similar to patent protection, it does not mean that piracy will not be encountered at all.

This does not mean that Jiayi's efforts are useless, reducing the difficulty of learning is very beneficial to the learning of mages, which can speed up the learning speed of mages, and can also train more mages. Of course, this can only be achieved until he has a great reputation among mages.

At least the prestige must reach worship, and the respect is probably not enough.

Moreover, the modular circle is also convenient for the modification and combination of the circle, for example, two circles are combined together, and a common module, such as an energy module and a control module.

Jia Yi has designed one, reconstructing an ice circle and a flame circle to share an energy supply module. At the time, the combination was successfully activated, but then it seemed that the magic in the ice and fire circles caused a conflict, and then it exploded.

Then Kaichi, who almost broke his phase, decided not to do this dangerous experiment until he learned the magic shield, but this practice showed that this design was undoubtedly feasible.
