Zhu Yunwen's emperor has not yet arrived in Taiyuan. The new Shanxi Zuobu Chief Envoy Huang Fu is already waiting outside the city with officials of the fifth rank and above from the Shanxi Chief Envoy Department, including Mo Cheng and other craftsmen who Zhu Yunwen specially wanted to see during this trip.

division.

He can be regarded as a new bureaucrat rising in the political arena. He has served successively as doctor, minister of the Ministry of Industry, right minister of the Ministry of State-owned Resources, etc. This time he parachuted into Shanxi to take over as the chief envoy from the left, for the purpose of Shanxi Coal Industry and to clean up Shanxi's officialdom.

Coal is black, and it will soon turn black no matter how much the officials here ignore it.

Because of his job experience, Huang Futai understands how much emphasis is placed on the mysterious Steam R&D Department of the Ministry of Industry. The Ministry of State-owned Resources also opens the door to the Steam Department, providing all the needs as quickly as possible.

Therefore, Huang Fu was not surprised at all that Zhu Yunwen traveled thousands of miles just for a steam engine.

"I, Huang Fu, the political envoy to the left of Shanxi, and my colleagues from the administrative envoy to the western part of Shanxi, are here to see my emperor and pay my respects to Jin'an."

Outside the chariot, dozens of people bowed in unison.

From the earliest days when military officials abolished the kneeling ceremony, then to the cabinet ministers who abolished the kneeling ceremony, until today the kneeling ceremony in the Ming Dynasty has been abolished, even for the common people. Zhu Yunqi never asked the people to kneel to him, it was just formed over thousands of years.

It is customary for the people to feel at a loss when they see the supreme king.

There is nothing to give to the emperor, so let’s kowtow to him.

This is roughly the basis of this thought.

Nowadays, basically only on the first day of the new year, the civil and military ministers in Beijing will bow when they go to court to pay Zhu Yunwen New Year greetings, which is just one bow and one kowtow.

It's not as good as the days when Zhu Yunwen was the great-grandson. At that time, it was still four bows.

The outer door opened, and the only voice that came out was Zhu Yunwen's voice: "No need to be polite, Mo Cheng comes up, the others can just go into the city and go back to the Yamen."

Unable to get a glimpse of the sky, the civil and military officials in Shanxi trembled inwardly, wondering if the emperor had encountered some unruly people along the way.

Impossible. We have been strictly guarding for more than a month. We have settled all the issues that can be settled by crying out for grievances. We have also sent commissioners to guard the house to keep an eye on the problems that cannot be settled. There is no reason to spread any gossip to the emperor's ears.

.

They were worried, but Mo Chengke didn't have so many messy thoughts. When they heard the sound, they walked onto the carriage excitedly, and were stopped and searched as soon as they stepped through the door.

Only when it was safe did you go into the inner room to see Zhu Yunwen.

When the latter saw Mo Cheng, he directly stretched out his hand and said: "Don't be polite, sit down and tell me how it went."

Mo Ben was not a person who liked courtesy. Besides, after working in scientific research for so many years, his personality was somewhat dull. Hearing this, he sat down and said: "To answer your Majesty's question, after we arrived in Shanxi more than a month ago, we did on-site measurements. According to

Based on the calculation of the depth of the coal well and the water accumulation, the required size of the steam engine has been roughly estimated. Now we have started to build the cylinder and boiler by hand. It is estimated that if it is fast, the cylinder will be built and can be put into use in ten days."

Except for a precision cylinder that requires careful construction and wastes time, other accessories are no longer a problem for Mo Cheng and others.

Coupled with the help of hundreds of local craftsmen temporarily transferred from Shanxi, large and small steel-making furnaces and furnaces can be used at will, and the work efficiency is naturally very fast.

Zhu Yunwen didn't want to talk too much with Mo Cheng about the principle and structure of the steam engine. This attitude was not only reflected in the steam engine. In the more than ten years since he traveled back in time, not a single invention of the Ming Dynasty was made by the emperor Zhu Yunwen.

Born through knowledge transfer.

Zhu Yunwen's grades in physics were indeed very poor, but he was a college graduate after all, so there was no reason for him to forget all the basic knowledge.

This is a kind of respect and trust for the ancestors.

You are treating yourself as a pure "indigenous" people, not as a transnational.

There is policy support from the top, a production environment from the middle, and resources from the bottom.

There are so many things that our ancestors could create. The creation of gunpowder was two thousand years ahead, and the compass and papermaking were more than a thousand years ahead. Everyone is familiar with these things.

Even in the field of optics that has approached modernity, the ‘telescope’ created by Sun Yunqiu of the Ming Dynasty was far ahead of the West.

These gave Zhu Yunwen confidence and also gave him an arrogant self-confidence.

The aim is to use ideas to change the Ming Dynasty, rather than using external forces to change the Ming Dynasty.

The strength of the Ming Dynasty today is not that of a leap. The superiority and foresight of time travel once made Zhu Yunwen think about using external forces to change the Ming Dynasty. The feedback he received was that it might cause instability and chaos in this era. In this case,

He began to change the thinking that led the Ming Dynasty to this period.

It was the idea of ​​gradual change in the entire Ming Dynasty society that changed the Ming Dynasty and gave the Ming Dynasty the stable social system it has today. This is a kind of stability and strength.

The system will not be disrupted by the replacement of a certain leader.

The cabinet is full of wolf nature and believes in the "gold and iron doctrine" proposed by Zhu Yunwen.

The court operates efficiently, which is a normal political response formed under Zhu Yunwen's repeated instructions.

Local cooperation is a national chess game developed under the five-year plan.

Later students and local scholars read "Jianwen Dadian" and understood the spirit of Emperor Jianwen.

Even if the new emperor wants to put the Ming Dynasty back on the track of its original time and space, re-establish the barriers of the scholar-peasant-industrial-business class, re-raise the supremacy banner of traditional Confucianism, and restore the Jin-Song scholar-lord system, it is already unrealistic and impossible.

Achieved.

What Zhu Yunwen wanted most was to hope that the history books of future generations would write about him and call him "a great intellectual giant".

A respectable politician and thinker.

This is far more worthwhile than praising him as a enterprising reformer.

"You are solely responsible for the work of the steam engine. I don't understand and will not interfere. I just have this idea."

Zhu Yunwen looked at Mo Cheng and said in deep thought: "Do you think it is possible to install a steam engine on this carriage under my butt? You have also seen that my carriage requires twelve very good horses to pull it. If you change

If it were a shoulder chariot, it would take sixty-four strong men to lift it."

Putting a steam engine into a carriage?

A thoughtful look appeared on Mo Cheng's face: "I bluntly say that your superior has not thought about this yet. It is unrealistic based on the thrust of today's steam engines."

"thrust?"

Zhu Yunwen was a little confused about this new vocabulary.

"That is, the work of pushing or raising a hundred kilograms of goods by twenty feet in one minute is called thrust."

Isn't this just horsepower?

This explanation suddenly made Zhu Yunwen feel enlightened and funny.

In the units after the unification of weights and measures, one kilogram of mass was six hundred grams, and one foot was equivalent to three meters.

There is no need to worry about how millimeter-level and nano-level technologies will be realized in the future when technology develops.

The length units of the Ming Dynasty include feet, feet, inches, minutes, centimeters, millimeters, and silk. These units are also decimal. If it gets smaller in the future, it will probably create a few more units below the silk.

Don’t ever feel the inexhaustible feeling of discomfort like one meter divided by one foot.

That's because we are used to modern usage and feel awkward. In fact, if Zhu Yunwen now changed the units of kilometers, meters, decimeters and centimeters, the whole Ming Dynasty would feel the same discomfort as we do.

"His Majesty's chariot requires twelve horses to pull it, and this kind of good horse from Arabia has calculated that even if a fully armed cavalry rides on it, under the weight of two hundred kilograms, it will sprint in an instant, and it will take an hour.

On a smooth road, it can travel nearly sixty miles, which is ten thousand feet.

Calculated, it means dragging two hundred kilograms and running eighty feet in one minute. The thrust reaches eight. His Majesty's chariot requires twelve such good horses to pull it at the same time. However, if it travels at full speed in one hour, it can only travel thirty miles.

The ground is 5,400 feet. Based on this calculation, the thrust required to push His Majesty's chariot is as high as 192."

Speaking of this, Mo Cheng frowned: "The steam engine we can create now, if we want to achieve a thrust of 192, if three cylinders move at the same time, the size of each one may reach one foot square."

Zhu Yunwen began to make crazy calculations in his heart.

Let's start with thrust. One hundred and ninety-two thrusts? If my memory is correct, the engine horsepower of the car I drove in my previous life seemed to be only one hundred and eighty. In other words, the engine of a modern car in the 21st century

When driving the emperor's chariot, he can only maintain a speed of forty or fifty miles per hour at most. For two hours per hour, the speed is only a little over ten kilometers per hour?

That's no slower than a bicycle.

Looking at the required volume of the cylinder, it is one foot square, which means the length, width and height are one foot each. The volume is one cubic foot, which is twenty-seven cubic meters.

One cylinder is so big. With three cylinders, it is almost as big as half a wheel.

Also consider the size of the boiler, bearings and transmission components.

The larger the cylinder, the larger the bearings and transmission components.

Once a boiler is used, a pure wooden wheel will definitely not work. It will need to be wrapped with a layer of heat-insulating and fire-resistant alloy. Even if it is just one layer, the weight will probably increase by more than 30%.

Looking back, a one-man steam carriage may be possible, but it is unrealistic for steam to propel one's own emperor's carriage.

After all, this thing is too big.

In fact, the calculation method Mo Cheng just gave is wrong.

Because when he calculated the power of the Arabian horse, he used the distance traveled in one hour to calculate the force, instead of using the unit of one minute to calculate the force, but he used one minute as the thrust provided by the steam engine.

Use constant data to calculate and apply battery life data, and you will definitely make mistakes during the experimental phase.

One hundred and ninety-two thrusts are simply impossible to push Zhu Yunwen's fully loaded emperor's chariot that can accommodate dozens of people, including resting, working, and even watching three to five beauties perform a small song and dance performance.

After all, the endurance of the Arabian horse is very poor, but its explosive power is extremely amazing, especially suitable for short-term cavalry battles in the cold weapon era.

Thinking that he would not be able to ride on a steam carriage within three to five years, Zhu Yunwen felt a little depressed, but his enthusiasm for observing steam engines was still high.

Even if it requires ten days of waiting time.

The holy driver entered Taiyuan without any obstruction, and there were no bloody bridges along the way. The Taiyuan that Zhu Yunwen saw through the car window was prosperous.

Countless people were almost isolated from a relatively 'safe' distance and watched from a distance. There were also many shabby boys who climbed to the roof to watch, but without exception, they all cheered and clapped their hands, shouting, 'Your Majesty.
