As mid-March enters the winter cold has completely faded, and the land outside Bangta City, which was originally frozen due to the severe cold, began to become wet and hot, and countless tender green grasses broke through the soil.

At this time, it is a good time to go out for a trip, so when it comes to a clear and good weather, there will always be countless young masters and ladies from noble families riding their own luxury carriages and driving out of Bangta City and heading towards the green wilderness outside the city.

Although the outside of Bangta City is surrounded by several straight and flat roads, the western suburbs are all over the ground because they are determined to be an industrial area by the city lord, and there are few green spaces left. However, the southern suburbs are not only retaining green grass and forests because they are determined to be a leisure and entertainment area by the city lord, but also opening up a canal to lure the river water of the Sandy River, transforming this southern suburbs, which were originally just a wasteland, into an excellent place with green mountains and green waters, and birds singing and flowers.

Today is another good day. The sun has just risen in the air, and countless carriages of noble families in the city drive out of the south gate of Bangta City and head towards the green area south of the city.

Countless noble young masters and ladies plan to take advantage of this good weather to go out in the suburbs and hold a relaxing and joyful outdoor feast.

However, today is a little different from usual.

Among the countless carriages rushing out of the city gate, there were two different things mixed in.

The young masters and ladies in the carriage heard the screams outside and lifted the curtains of the carriage one after another. They saw two people sitting on something made of two wheels and an iron bracket, with flat bodies and looking strange.

The two men stepped on two pedals, constantly pedaling under their feet, turning quickly around a disc.

With this disc turntable, the two wheels on the iron rack kept rolling forward, driving the two people to keep moving forward on the road.

What surprised everyone was that the strange thing that the two people sat down looked very thin, with only one bracket except for the two wheels. However, they could take the two people above to move forward quickly, and in an instant, they surpassed several carriages and ran to the front of many noble young masters and ladies.

Seeing the two men walking on this unknown strange thing, they were moving forward quickly on the highway like lightning. Whether it was the noble young masters and ladies on the carriage or the pedestrians on the road, they could not help but be stunned.

What exactly were the two sitting under their butts? How could they take them so fast?

However, the two people disappeared far away from the road, making everyone's questions unable to be answered.

The next day was another sunny day.

As usual, countless carriages drove out of the city gate and ran out of the city.

But at the same time at nine o'clock in the morning, the two strange things rushed out of the city gate again with two people, surpassing countless carriages and disappearing at the far end of the road.

People's questions are getting deeper.

On the third day, it was sunny again.

The same situation happened again.

Day 4...

Day 5...

...

It was a rare sunny day for a whole week. Every day, countless noble young masters and ladies wanted to go out for an outing, but every day, the two strange things rushed out of the city gate with two people and then quickly disappeared from everyone's sight.

The accumulation of seven consecutive days has allowed this mysterious strange thing to spread throughout Bangta City, arousing the curiosity in everyone's hearts.

Someone who was flirting had already been waiting outside the South City Gate a few days later and drew the two strange things.

After analysis, everyone found that the principle of these two strange things was actually very simple. They just pressed on the ground with two flat tires, supported by an iron frame, and then used two connected gears as driving. Finally, the person above was asked to use his foot pedals as power.

However, the principle seems very simple. It is really incredible that these two weird things can actually run so fast under human power.

At the beginning, people didn't know what this thing was and where it came out. But later a careful person guessed something from those two tires.

Now only the Xinfei Chamber of Commerce produces tires, and the Xinfei Chamber of Commerce has always been able to produce all kinds of strange things. Then these two strange things are most likely to be magical machinery newly developed by the Xinfei Chamber of Commerce!

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

Early in the morning of the eighth day, the newly released "Bonta Daily" finally revealed the answer.

People are rightly guessing that these two strange things are indeed the latest products developed by the Xinfei Chamber of Commerce. But they are different from what everyone imagines, and this thing has nothing to do with magic.

This thing called a bicycle is a human machine, completely powered by humans and does not contain any magic.

But even if it is just human-powered, as long as the bicycle rider is strong enough, the bicycle can still be fast.

According to internal information obtained by Bonta Daily, it is said that when the New Air Chamber of Commerce is testing bicycles, it is said that when riding a bicycle, it can even ride a bicycle from Bonta City as early as the morning and arrive at Luoyu Valley before noon.

You should know that Luoyu Valley and Bangta City are 60 kilometers apart, and it will take more than three hours to travel with the best carriage.

The speed of this bicycle is actually not much slower than the best carriage!

When people saw the report from Bonta Daily, they were instantly excited.

With such a good thing, it will be much more convenient when traveling in the future!

Although a carriage is good, raising horses is simply unbearable for ordinary families.

Although the urban public transportation system of Bangta City has been gradually established, and it is possible to get to most places you want to go by carriage, but riding a carriage costs money, not to mention that there are many places where carriages cannot go.

Compared to this simple and lightweight bicycle, the carriage undoubtedly looks much more bulky.

So after confirming that the bicycle was indeed produced by the Xinfei Chamber of Commerce, the gate of the Xinfei Chamber of Commerce Product Service Center in the city was instantly squeezed out by countless people. Countless people came to ask when the bicycle would start selling. Everyone couldn't wait to buy one.

"It seems that there is no need to worry about the sales of this bicycle." Xu Yi laughed, put down the Bonta Daily in his hand, turned to look at the bicycle with high-speed tires in the R&D workshop of the Magic Machine Tool, driven by a wind-type magic engine.

Strictly speaking, this bicycle is just an accompanying product developed by Xu Yi to develop the engine.

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

For example, a series of technologies that can be used in many aspects, such as power structure, bearing drive, gear casting, etc., will be used in bicycle production.

Xu Yi asked Kambi and others to develop bicycles. In addition to adding a new product to the Xinfei Chamber of Commerce, he also allowed Kambi and others to gain more experience and theoretical knowledge about these technologies during the research and development process.

This is very different from that on Earth.

Mechanical engineers on earth all learn theoretical knowledge first and then start practical production.

However, the mechanical engineers represented by Cambi in the Xinfei Chamber of Commerce first carried out practical production under the guidance of Xu Yi and then learned theoretical knowledge.

This is also impossible. Xu Yi wants to accelerate the development of the industrial system. He can only forcibly instill his theoretical knowledge into them like this.

Fortunately, dwarves such as Cambi have super talent in this regard. Xu Yi only mentioned a little, so they could understand deeply and even learn from one example.

Through the development of bicycles, Cambi and others have become mechanical engineers with a deep understanding of power theory.

The next step is to let them combine the wind-type magic engine that has been developed to a certain extent to combine the bicycle.

If another magic bicycle with a wind-type magic engine as the driving force can be built, it means that the research and development of magic engines can be truly used in practice.

The experiment that Cambie and others are doing now is a test of the power output stability of wind-type magic engines and the test of bearing strength.

The test has been going on for a full ten days, but the effect has always made Xu Yi not very satisfied.

First of all, the wind-type magic engine cannot keep the output all the time, but it often stops without warning, and the output power is sometimes fast and sometimes slow.

After careful examination by Xu Yi and several researchers from the Magic Research Institute, it was found that this was because the wind-type magic array engraved inside the engine rotated at high speed, causing the air flow inside the engine to be chaotic, which also had a certain impact on the magic array, thus affecting the output power.

If this influence accumulates to a certain level, the magic circle will temporarily lose its effect, thus causing the engine to lose its driving force.

Another very important issue is the material issue.

The gears and bearings of the bicycle are not very problematic at low speeds, but after maintaining high speed rotation for a long time, the loss will increase greatly.

According to the evaluation, if the wind-type magic engine is maintained at the highest speed, whether it is the bearing of the bicycle or the bearing of the engine itself, it may not last ten hours and there will be extremely strong wear or even breakage.

Xu Yi has no choice but to do this for the time being.

Because this is a material problem, and the material problem happens to be the most difficult problem in the industrial system.

Although the industrial system of the Celestial Empire on Earth is basically perfect, it has always lagged behind in material technology.

As a mechanical engineer of the Celestial Empire, Xu Yi was not particularly good at material issues, and coupled with national restrictions, he was even more unable to master the most advanced material technology.

For this question, he could only pin his hopes on the Materials Research Institute led by the Slubi Patriarch.

Before this, the Materials Research Institute, led by the Slubi Patriarch, had already given Xu Yi a lot of surprises.

Now Xu Yi handed over this question to him and waited until the non-ferrous metal veins on the black rice wasteland were mined and melted. I believe that the leader of the Shilubi will hand over Xu Yi a satisfactory answer.

Before this, I could only wait patiently.

Even if Xu Yi was anxious about engine research and development, there was no need to be negligent in the research and development of mechanical technology.

As a genius mechanical engineer on earth, Xu Yi has this enlightenment and also has this patience.
