Ivey listened to Waters' words and hurriedly probed over: "It's really three." ”

He split a paper into three parts, one about cars, one about bearings, and one about tires. It's a chicken thief. ”

"Because the latter two items are not only part of the bike, they can also be listed separately, and the bearings can also be used in other vehicles, or on the doors. Tires can also be fitted to horse-drawn carriages. Ivy read the paper carefully and said.

Having said that, he was envious of the fact that he had published three papers on an invention.

"But it's a good idea, so that if you publish a paper three times, you can get three licenses. It also increases the cost of other mages to circumvent. ”

"Although it is three papers, in fact, the quality of the bicycle is the worst, after all, it is just a new look, and the tire, although it is to explore the new use of eucommia gum, but it is not as good as the floating carriage, and the extraction of eucommia gum is not his invention, it is the use of No. 7 extractant, and the extraction method has long existed. The most important thing is actually this paper on bearings, which is not only a more labor-saving part, but also defines a force called 'friction'. ”

Ivey is the most respectful of the paper on bearings, thinking that this paper can actually be published to a higher level is impurities, and it is only in order to cooperate with the other two papers that it was published on "Magical Strange Things", which makes "Magical Strange Things" take advantage.

"Friction,' the force that hinders the relative motion (or relative tendency of motion) of an object is called friction. The direction of frictional force is opposite to the direction of the relative motion (or relative tendency of motion) of the object. His definition is peculiar, and it's a bit of a word. This friction, when he said this, he knew that it existed everywhere in life, but it seems that someone has elaborated on this, and it always feels a little familiar. ”

Vorster said that there seemed to be some doubts that something that had been discovered before could be written for a paper. Probably deep down in his heart he is jealous of a person who is younger than himself, but his achievements are better than his own, and he always has some resistance to young geniuses in his heart.

Ivey said, "Yes, the old magicians actually knew friction, and they had success, such as greasy magic, which is to use friction to make people's feet unstable. ”

Then he still has the face to publish the paper, look at the title of this paper - on the systematic elaboration and application of friction, on the principle and use of bearings. Again, put friction first. ”

No, this paper summarizes and discusses friction in detail, and divides friction into three types: static friction, rolling friction, and sliding friction, and also puts forward two hypotheses about friction, the theory of concave-convex meshing and the theory of adhesion.

"He was the first to sum up friction. ”

Ivey admires Jiayi's achievements very much, and does not despise Jiayi because of his young age, Vorster is actually convinced in his heart, but he does not admit defeat.

"Let's go make this bike!"

Ivy was stunned for a moment by what he said, surprised at how the other party changed the topic so quickly.

He was about to speak, when suddenly there was a wave of people in front of him, it was the other people in this group who arrived, since it was called a group, of course it couldn't be just Ivey and Vorster.

"What are you talking about?" asked a tall, but ordinary-looking woman in front of you, "Is there any new potion recipe published?"

"Mu Li, you guys came late today, why did you come here together?" Vorster said, standing up.

Without waiting for an answer, he continued: "Let's look at a new paper with the invention of a 'bicycle', and I think we should do this and subsidize the cost of the experiment a little." ”

"What 'bicycles', horse-drawn carriages are not allowed in schools. ”

Vorster felt that he couldn't speak clearly, so he showed them the paper in the magazine.

After reading the magazine, everyone began to have a heated discussion, but the point was that there was still such an operation - splitting a paper into three copies and publishing it. Everyone has expressed their long-term knowledge, and they must inherit this fine tradition in the future.

However, it is not easy to split the paper and ensure the independence of each paper without saying something.

After a long time, everyone finally returned to the bicycle, discussed for a long time, and finally agreed on the opinion, at this time, the time was past noon.

By the end, they summarized the pros and cons of the bike.

Longgen College is still very large, there are many walks to come and go, and there are living areas around the school, this area is even larger. However, horse-drawn carriages are not allowed to drive on campus, and the carriages are too large and can be used in the open. The bicycle is small in size, easy to use, and most importantly not in the ban, so there will be a certain market.

But after all, bicycles are new vehicles, and the style is "weird", people don't understand it, and it is difficult to grasp the balance, for fear that people in the school will not accept it. So they decided to make a few cars out and drive them on campus themselves, as invisible advertisements, and then launch the bikes when the time came. Let's also test how the people in the school are receiving bicycles.

There is also the fact that bicycles are published papers after all, they can make them, and other people can make them, so they need to refine the characteristics, and the inscribed magic array needs to be well designed, and a rune that reduces weight is not enough.

Fortunately, although Jiayi has published three papers on a bicycle, there is authorization at the end of the paper, and if it is made by an individual, he only needs to pay the bicycle for the authorization of one paper. However, if you want to use bearings or tires in other areas, you need to pay the full license fee.

Vorster and the others are actually playing a side game, because many of them are not actually individuals, but they are actually just playing tickets, and they don't want to do it all the time, they just want to subsidize the cost of doing experiments a little.

After they discussed it, they began to divide the work, some people went to purchase materials, some people went to design rune circles, and some people went to prepare the site for making bicycles.

Although they are all students, they are all formal mages after all, and making bicycles is not a burden for them, even Jiayi can successfully make them, or research and development, they follow the complete drawings, and the cost will only be lower than Jiayi.

Five days later, they finally built their first bike.

"Here, let me try it out for you and see my skills. ”

Vorster took the bike, stepped over it, and was about to ride. But it was the first time he was riding, and as soon as he pedaled, the bike fell to the side.

"Haha.... That's your technique..."

He tried several times, but it always didn't work, and he had to wonder if there was something wrong with the car. He stopped, thought for a moment, blessed himself with a balancing technique, and also called the grace of a cat, and rode again.

This time, there was no problem, with the blessing of magic, he was able to maintain a good balance, never overturned, and pedaled the wheels with his feet fast.

"Look, how's it going? I'll just say I'm good at my skills. Vorster laughed, then let go of the front of the car with both hands and opened his arms in a hug gesture.

It's a pity that the front of the car is crooked, if he hadn't shot it out with magic in an instant, and then released the Feather Falling Technique to fall, he would definitely kowtow and bleed. But the car was not spared, and the steel rims of the wheels were bent.

After 7 or 8 days, almost everyone in the group had a bicycle, and then they started riding it to class, eating, and walking around every day so that everyone in the school could see it.

Their methods worked, not everyone would subscribe to Magical Wonders, and even those who knew about it would not necessarily choose to make their own, plus there were quite a few apprentices in the school. Two days later, someone came to inquire about the origin of the bike, and five days later, the first bike was sold.

A month later, they sold hundreds of bicycles, plus some people who didn't have the money to make their own bicycles, and even other mages sold bicycles in their own way, and it was conservatively estimated that there were more than 300 bicycles in the entire school. Then, as long as you are within the school area, there are bicycles speeding by at all times.

These also boost the sales of the bikes, making the sales of the bikes higher.
