In mid-March, the cold in winter has completely faded. The land that had been frozen in Bunta City because of the cold began to get hot and humid, and countless verdant grasses broke through the soil.

At this time, it is a good time to go out, so as soon as the weather is fine, there will be countless nobles’ young Masters who ride out of their luxury caries and drive out of Bunta City to the green fields outside the city. Progressive.

Today, outside Bunta City, it has been surrounded by several straight and flat roads. The western suburbs are all known as industrial areas by the Sir City Lord. They are all kinds of factories, and there are few green spaces left, but the southern suburbs are because of Sir. City Lord is determined to be a recreation area, not only retaining green grass, but also opening a canal to bring in the waters of the Sandy River, transforming the southern suburbs, which was originally a wilderness, into an existing green hills and Clear waters, the perfect place for Birds, Speech, Flowers, Fragrances.

Today is another sunny day, the sun has just risen in the air, and the carriages of countless aristocratic families have sailed out of the south gate of Bunta City and headed for a greenery in the south of the city.

Countless aristocrats, Young Master, are planning to play in the suburbs with this good weather, and host a relaxing and joyful wild feast.

However, today, peace is often different.

In the numerous carriages that rushed out of the city gate, there were two different things.

The young Master on the carriage heard the exclamation outside, and opened the curtains of the carriage, and saw that on the road leading to the southern suburbs, two people were sitting on a wheel consisting of two wheels and an iron bracket. It’s flat and looks strange.

Two people stepped on the two pedals and kept turning around their wheels as they squatted.

With the disc carousel, the two wheels on the iron shelf kept rolling forward, driving two people to keep on the road.

What surprised everyone was that the strange things that the two men sat down obviously looked very thin. There was only one bracket except for the two wheels, but they could fly fast with the two people above. A number of carriages went to the front of many noble Miss Young Masters.

Watching the two people follow this unknown thing fast as lightning, generally on the road, whether it is the noble Miss Young Master on the carriage, or the pedestrians on the road, can not help but stay.

What exactly is the two people sitting under the ass? How can I run with them so fast?

However, the two people actually disappeared into the distance of the road, so that the questions in the hearts of all people could not be answered.

The next day was another sunny day.

As usual, there are countless carriages driving out of the city gate and heading out of the city.

But at the same morning at nine o’clock, the two weird things once again carried two people out of the city gate, once again surpassed countless cars and disappeared at the far end of the road.

The doubts in people’s minds are deeper.

On the third day, it was sunny again.

The same situation is repeated again.

The fourth day…

The fifth day…

……

For a week in a row, every day is a rare sunny day. Every day, countless noble young masters want to go out for a green outing, but every day there are two strange things carrying two people out of the city gate, and then quickly disappear in all In the sight of the person.

The accumulation of seven days in a row made this mysterious strange thing spread throughout the city of Bunta City, evoking the curiosity of everyone.

Someone who had a good thing had waited a few days before the South city gate, and painted the appearance of the two strange things.

After the analysis, everyone found that the two strange things are actually very simple, just relying on two flat tires pressed to the ground, with an iron shelf as a support, and then using two connected gears as a drive Finally, let the above person use the foot pedal as the driving force that’s all.

However, the principle seems to be very simple. These two strange things can actually run so fast under the driving force of manpower, which is really incredible.

At the beginning, people didn’t know what it was, from where it came from, but then the careful people guessed it from the two tires.

This kind of tire is now only available in the Fresh Flight Chamber of Commerce, and the Fresh Flight Chamber of Commerce has always been able to produce all sorts of weird things. These two strange things are most likely the Fresh Flight Chamber of Commerce. Developed Magic Machinery!

All doubts and guesses were finally answered on the eighth day. ,

Early in the morning on the eighth day, the newly released National Tower Daily finally revealed the answer.

People guessed it correctly. These two strange things are indeed the latest products developed by the Fresh Flight Chamber of Commerce, but they are not the same as everyone imagined. This thing has nothing to do with Magic.

This thing called a bicycle is a kind of manpower machine, driven entirely by humans, without any Magic.

But even if it’s just human-powered, as long as the person riding the bicycle is strong enough, it can still make the speed of the bicycle fast.

According to internal news from National Tower Daily, the Fresh Flight Chamber of Commerce is said to be able to ride a bike from Bunta City in the early morning when testing a bicycle. It will be able to reach the Falling Rain Valley before noon.

To know that Falling Rain Valley and Bunta City are 60 kilometers apart, it takes more than three hours to run with the best carriage.

The speed of this bike is actually much slower than the best carriage!

Seeing the report of National Tower Daily, people instantly boiled up.

There is such a good thing, it is much more convenient when you travel later!

Carriage Although good, raising a horse can’t afford it for the average family.

Although the urban public transportation system of Bunta City is now gradually established, it is possible to sit on the carriage to reach most of the places that I want to go, but the carriage is expensive, and there are many places where the carriage can’t go.

Compared to this simple and lightweight bike, the carriage is undoubtedly much more cumbersome.

So after confirming that the bicycle was produced by the Fresh Flight Chamber of Commerce, the door of the Fresh Flight Chamber of Commerce product service center in the city was instantly smashed by countless people, and countless people ran to ask when the bicycle would be. Starting to sell, everyone can’t wait to buy one.

“It seems that the sales of this bicycle is not awkward.” Xu Yi laughed, put down the “National Tower Daily” in his hand, turned to look at towards Magic Powered Machine Tool R & D workshop is driven by a Wind Element Magic Engine, tire high speed Rotating bicycle.

Strictly speaking, this bicycle is just an accessory that Xu Yi developed for the development of the engine.

Although bicycles are only a commercial product that is not very important in the light industrial system, bicycles contain many engineering technologies that are extremely important.

For example, power construction, bearing drive, gear castings, etc., can be applied to a variety of technologies, which are used in bicycle production.

Xu Yi asked Kanbe and the others to develop bicycles. In addition to adding a new product to the Fresh Flight Chamber of Commerce, Kanbe and the others gained more experience and theoretical knowledge of these technologies in the development process.

This is very different from Earth.

The Mechanical Engineers on Earth first learned theoretical knowledge and then began to practice production.

The Mechanical Engineers represented by Kanbe in the Fresh Flight Chamber of Commerce are practiced under the guidance of Xu Yi and then learn theoretical knowledge.

This is also a no-brainer. Xu Yi wants to accelerate the development of the industrial system, and can only inculcate his theoretical knowledge to them.

Fortunately, Kanbe and other dwarfs are really strong innate talents in this respect. Xu Yi is only a little bit of a point, they can understand deeply, and even can give inferences.

By developing bicycles, Kanbe and the others have become Mechanical Engineers with a deep understanding of dynamic theory.

Next, Xu Yi is letting them combine the bicycles that have been developed to a certain degree of Wind Element Magic Engine.

If you can recreate a Magic Element Magic Engine as the driving force of the Magic Power bike, it means that the development of the Magic Power engine can be really used in practice.

The experiment that Kanbe and the others are doing now is a power output stability test for the Wind Element Magic Engine and a test of bearing strength.

Now this test has been going on for ten days, but the effect has always made Xu Yi less satisfied.

The first is that the Wind Element Magic Engine can’t keep the output all the time, but it often stops without warning, and the output power is sometimes slow and sometimes slow.

After careful inspection by Xu Yi and several researchers at the Magic Research Institute, it was found that this was because the magic array imprinted inside the engine caused the air flow inside the engine to be disordered due to the high-speed rotation of the internal bearings of the engine, thus the magic array. It also has a certain impact, which affects the output power.

If this effect accumulates to a certain extent, the magic array will temporarily lose its effect, causing the engine to lose its driving force.

There is also a very important issue, or a material issue.

Bicycle gears and bearings are not too big at low speed, but the loss is greatly increased after maintaining high speed for a long time.

According to the evaluation, if the speed of the Wind Element Magic Engine is kept at the highest speed, whether it is the bearing of the bicycle or the bearing of the engine itself, it is feared that it will be extremely ten years of wear and even break.

Xu Yi has no way at this moment.

Because this is a material problem, and the material problem is just the most difficult problem in the industrial system.

China on Earth Although the industrial system is basically perfect, it has lagged behind in material technology.

As a Mechanical Engineer in China, Xu Yi is not particularly good at material issues. Coupled with national restrictions, it is even less able to master the most advanced materials technology.

For this issue, he can only pin his hopes on the research institute led by Siluka patriarch.

Prior to this, the Research Institute, led by Siluka patriarch, had given Xu Yi a lot of surprises.

Now Xu Yi will give this question to him, and then wait until the non-ferrous metal veins on Heimi Wastelands are mined and smelt. I believe that Siluka patriarch will give Xu Yi a satisfactory answer.

Before that, I can only wait patiently.

Even if Xu Yi is eager to develop the engine, the mechanical technology research and development can not be neglected.

As a genius Mechanical Engineer on Earth, Xu Yi has this awareness and also has this patience. (To be continued.)
