The Ministry of Industry has always been the largest department of the imperial court, but this does not mean that there are many high-ranking officials in the Ministry of Industry, but because the Ministry of Industry manages the most craftsmen.

The status of a craftsman is low, even if he becomes a small official, in the eyes of those who read, he is still inferior.

Therefore, for more than 1,000 years, the ranking of the Ministry of Industry has been the last of the six.

Since four years ago, the Ministry of Industry has added a Technology Patent Division, and this originally inconspicuous yamen has developed into a franchise department with nearly 1,000 craftsmen in just four years.

And Liu Jie, who was originally squeezed out by the Ministry of Industry and was arranged to the Patent Division, has changed from a marginal figure to a hot celebrity in Beijing in the past few years.

As a descendant of the criminal minister Liu Bowen, Liu Jie endured white eyes and exclusion in the capital for the glory of the family, and now he finally has a bright future.

In the dialogue with Zhu Zhanji at the beginning, he had a good grasp of Zhu Zhanji's mind, and now all the work of the Patent Department is for technology promotion services.

For each patented technology that has been applied, the patent department will have a special person to classify the technology without waiting for the patent certificate to come down.

Different industries, with different people in charge, then spread the word across the country.

Whether the applicant wants it or not, in addition to the details of the confidentiality, the use and function of this technology will be publicized in detail.

At such times, most people, except for large merchants, will choose to license patents.

Therefore, from the 14th to the 18th year of Yongle, although the Ministry of Industry carried out engineering construction all over the country because of cement, it could not cover up the limelight of the Patent Division.

Today's Yingtianfu Dental Stores, and dental stores in major state capitals, have opened patent services. A wide variety of new technologies have been fully applied.

Liu Jie's fame is growing, and the patent department is making more and more profits.

It's not that no one wants to squeeze Liu Jie out, but Liu Jie has already registered in front of Zhu Zhanji, and Zhu Zhanji gave Liu Jie a piece of his grandson's order.

In addition, Song Li, the secretary of the Ministry of Industry, had already been instructed by Zhu Zhanji to protect this Liu Jie and let him sit in Langzhong's position safely.

The north side of Chang'an Fang in Yingtian Mansion, by the moat of the inner treasury of the Imperial Palace, was originally a flat land that was separated.

During the Hongwu Dynasty, the population of Yingtianfu was less than one million, and for the safety of the imperial palace, houses were not allowed to be built here.

However, after the Yongle Dynasty, the population of Yingtianfu increased year after year. In addition, overseas countries have set up Honglu Temple in Yingtianfu, arranged envoys, and overseas businessmen have come and gone, which is overcrowded.

In the twelfth year of Yongle, Yingtianfu's registered population reached 1.03 million, and the long-term resident population reached more than 150,000.

According to the population statistics of Yongle in the 16th year, the registered population exceeded 1.2 million, and the long-term resident population exceeded 300,000.

In other words, the population of the entire Ying Tianfu exceeded 1.5 million.

This is not a city with high-rise buildings in later generations, most of the people today live in bungalows, and the living area of civil and military officials is very large, resulting in more and more crowded people.

The establishment of the Jiajiang Industrial Zone has eased the housing shortage in Yingtianfu to a certain extent, because many people have moved out of the city on their own initiative to work there.

However, housing and public land in Yingtianfu are still becoming more and more scarce.

In May, Song Li wrote a letter and reported the situation to Zhu Zhanji.

After experiencing the house speculation in later generations, Zhu Zhanji certainly knows how to control this situation.

First of all, he ordered that all the construction of the houses in Tianfu should be planned in a unified manner in the future.

With cement and prefabricated panels, it is not difficult for Daming to build a five- or six-story house at all.

But the difficulty is the supporting facilities, such as water supply and discharge.

If there is no water supply, how can the people use water? How to cook? How do I flush the toilet?

The advent of the steam engine can solve this problem, but it is difficult to popularize it.

The people who lived in the buildings must be poor, and it was impossible to expect the poor to buy an expensive steam engine for the purpose of loading and distributing water.

However, the yamen can.

The Patent Department of the Ministry of Industry was originally just a small yamen, but in the past few years, it has developed into a large organization with nearly 1,000 employees.

Not counting the officials in the various prefectures and cities, there are almost 500 people in the capital alone, who are responsible for various affairs.

The Ministry of Industry arranged a small courtyard for them in the Yamen of the Ministry of Industry, and even people could not stand.

Moreover, more and more information also needed a place to store it, so the patent department applied several times and asked the Ministry of Industry to allow them to build a new yamen.

But this matter is not so easy to operate, Zhu Di is not familiar with the affairs of the patent department, and has always thought that this is a money-making yamen by Zhu Zhanji.

Since it is to collect money, of course, the more money you save, the better. Therefore, the look of the patent department was naturally rejected.

It wasn't until Zhu Zhanji came back that Liu Jie mentioned practical difficulties to him that Zhu Zhanji had the mind to prepare for the unified planning of Yingtianfu and the construction of a new city.

The residential area is not easy to rebuild now, but the major yamen of the imperial court, which occupies half of the city, can be rebuilt first.

It is not a burden for a yamen to get a steam engine for water supply and discharge. What's more, in winter, this steam engine can also provide heating.

After looking at the map of Ying Tianfu for a few days, he called Wu Zhong and Karl Soli over and conducted a detailed analysis of the entire environment of Tianfu.

Zhu Zhanji decided to build a large number of buildings and rebuild Yingtianfu, and the first step was to rebuild the major yamen of the imperial court.

In the past, all the houses were bungalows, and each yamen occupied a vast area, occupying a large area of land, and the land utilization rate was too low.

However, if a high-rise building is built, it does not need to be too high, three to six floors can be used, which can greatly improve the office conditions of hundreds of officials, and can also save a large area of land for Ying Tianfu.

The patent department had a large number of personnel, and the house was the most tense, and it became the first yamen to be built.

Because the level is relatively low, this yamen will not be built on the street outside Chengtianmen, but on the north side of Chang'anfang. And there will be five floors, only slightly lower than the Fengtian Temple.

The five-storey building, which covers an area of 2,000 square meters and is up to five floors, has attracted the attention of countless people from the very beginning.

Everyone knows that this will be a new beginning in the history of Ming architecture.

The house has a distinctly East-meets-West style, with a Baroque architectural framework and an Oriental roof and eaves. Moreover, this is only the side of the street, and there is an oriental-style courtyard pattern and garden pattern behind it.

This method was proposed by Zhu Zhanji, but it was not his originality, because he had seen this style of architecture in Harbin in his previous life, and only the roofs and eaves did not use Chinese style.

In a way, the Baroque architecture has a structure that fits perfectly with the Chinese style. They are symmetrical in shape, which is in line with the Chinese style.

In terms of internal architecture, they pay attention to the use of space and light, which is far superior to other architectural styles, and can only be matched by the Mediterranean style.

Like the new Chinese architectural style of later generations, although it looks beautiful, the use of light inside the house is hundreds of years behind.

The Mediterranean style is incompatible with the architectural style of the Ming Dynasty, and in the eyes of the Ming people, that architectural style is too ugly.

What's more, today's Baroque architectural style has not yet taken shape in the West, and now the Ming Dynasty will carry forward this style, which will become the new Ming architectural style.

In this, Zhu Zhanji abandoned the exaggerated artistic style of the Baroque style, and did not want them to deliberately design some lines into curved forms in order to pursue visual effects.

The architecture of the Chinese still pays attention to squareness, which is nothing more than more attention to the meaning in the details.

The term Baroque originally meant an irregularly shaped pearl and had a derogatory connotation at the time, when its flamboyant, ostentatious style was considered a disparage to the Renaissance style.

But now this style is determined under the leadership of Zhu Zhanji, the Ming people already like complicated styles, this kind of gorgeous and ostentatious, in line with the mentality of the first in today's world.

Especially on the main structure, it is still the wide eaves design style of the Ming Dynasty since ancient times.

The roofs of ancient Chinese buildings played a particularly important role in building facades. The eaves that stretch out far away, the elastic eaves curve, the slightly curved roof formed by the lifting frame, the slightly warped corners (looking up at the corners, the corner rafters spread out like birds' wings, so they are called "wing angles") and the changes in the form of many roofs such as hard mountains, hanging mountains, rest mountains, palaces, cumulating points, cross ridges, domes, heavy eaves, etc., together with brilliant and dazzling glazed tiles, make the building produce a unique and strong visual effect and artistic appeal.

By combining the roofs, the shape and contour of the building are richer. And from a high altitude, the roof effect is better, which means that the "fifth façade" of Chinese architecture is the most attractive.

Therefore, when the blueprint of the Patent Division building was announced, it immediately attracted the attention of countless people.

This new house is stronger, heavier, and more functional. And, after the installation of glass, the interior of the house has much more light than today's houses, and there is no need to light it up for daytime work.

Of course, this gorgeous, heavy building is mainly office space. At the same time, the architectural style of the houses where the common people lived became a difficult problem.

Today, the people are still very poor, and most families have no money to spare. Whether it is a new Chinese style or a unit building, the construction cost is much higher than that of most of today's houses built of mud bricks and loess.

Zhu Zhanji doesn't want to be like later generations, speculating the price of the house into the sky, so that ordinary people need to run around for a lifetime for a house.

He knows very well that the speculation of housing prices is related to the living habits of the people, and the country needs a kind of large-scale consumption to take out the money in the pockets of the people to stimulate consumption and the market.

But what is superior to today's Ming is that as long as the energy from overseas territories continues to flow back resources, as long as the scientific and technological level of Daming has always been leading.

At least within one or two hundred years, the siphon effect produced by the Ming Dynasty can nourish the entire Ming Dynasty.

Therefore, Zhu Zhanji finally decided that even if the imperial court did not earn a tael of silver, it would first unify the housing of the people in Yingtianfu.

First of all, the façade of the street should be built into a three-story building with a store in front of the store and a residence in the back, so that there is no need to consider the water supply and drainage now, but it can solve the congestion problem of Yingtianfu.

The second is the neighborhood, which was first rebuilt by the wealthy neighborhood, and the houses are uniformly in a two- or three-story neo-Chinese style to reduce the floor space.

The saved land and the houses built can be sold at a high price to make up for the losses of the imperial court.

In addition, Zhu Zhanji asked the Ministry of Industry to actively study the improvement of water supply and water supply equipment, and strive to build a water tower in every neighborhood in the future to supply the daily water supply of the entire neighborhood.

After this technological breakthrough, it will be possible to build five- or six-story unit buildings, which will greatly improve the land utilization rate of Yingtianfu.

Of course, the most important thing is not to turn houses into commodities, because if houses are turned into commodities, the order of the whole society will be in chaos.

The best way to do this is to turn the house into a status hierarchy and make it easy to distinguish at a glance.

Today's Ming Dynasty has royal families, clans, nobles, officials, scholars, common people (merchants, farmers, etc.), and now there are more overseas students, envoys, and hires.

In addition to clothing, the house should also be an important criterion for distinguishing status.

While asking the Ministry of Industry and the Ministry of Rites to standardize the classification of buildings under various regulations, Zhu Zhanji issued an order to carry out unified planning for urban construction throughout the Ming Dynasty, and stopped the construction of various new houses.

Each different region should have a different style of architecture, which needs to be practical and sturdy and can be preserved for a long time.

In later generations, the phenomenon of urban homogenization was very serious. In many parts of the country, whether in the south, in the north, in the east or in the west, the houses are almost identical, and there is no novelty at all.

This is not desirable, although it saves some thought, but it is a great waste of resources.

If a city has its own different styles and characteristics, then in a few hundred years, the development of tourism in the country will be far more popular than in later generations.

More importantly, the construction of sewers in every city must first be put on the agenda, and the construction of a city is not how beautiful it is, but how powerful it is.

You can't flood into a river as soon as it rains, and if it doesn't rain for a while, you start to run out of water again.

Urban construction needs to be forward-looking, whether it is greening, drainage, garbage disposal, water and electricity supply, road construction, there should be enough space reserved.

Ying Tianfu should be called a model and become a model for the entire Ming Dynasty, so that cities in other places can initially have the urban functions of later generations.

As far as roads are concerned, the original Ming Dynasty only had horse-drawn carriages and ox carts, and the roads were narrow.

Zhu Zhanji wanted to build a city train in Yingtianfu, and many buildings had to be demolished.

In the future, if you have a car, the current road will be even more difficult.

Therefore, in response to the urban transformation of Tianfu, it is necessary to fully consider these problems and reserve the bus lane and the tram track.

There is a big problem here, and that is the limitation of the city wall.

Ancient cities were small and crowded because of the limitations of the city walls. The city wall has played an irreplaceable role for a long time.

But when explosives have been invented, new muskets have been invented, and the power of war has been greatly expanded, is the role of the city wall still so important?

Of course not!

When the time entered the hottest July, Zhu Zhanji proposed the possibility of canceling the construction of the city wall in the future Ming Dynasty at the court meeting on the first day of the seventh month.

This proposal was opposed by almost everyone, and the city wall was the security of the common people of this era, and it was also the support of these ministers.

Don't want a city wall, what's the difference between this and stripping yourself naked and facing the other party's broadsword?

In order to persuade these ministers, Zhu Zhanji brought hundreds of civil and military officials to the Qilin Gate in the east of the outer city of Yingtianfu.

The Qilin Gate is named after the two stone unicorns located in the tomb road of Emperor Wu of the Song Dynasty, Liu Yu Chuning. It was built in the 23rd year of Hongwu in the Ming Dynasty, and was built to make up for and strengthen the defense of the Ming city wall of Nanjing.

The main body of the castle wall is mainly hills and earth, and bricks are only added to the weak areas of the castle gate, and the height of the castle is about 8 to 10 meters, and the width of the castle wall is 6 to 8 meters.

This city gate is very high because Zhu Gaochi lives in the hot spring courtyard today, and most of the people in the Jiangnan area enter Beijing, so the utilization rate is very high.

However, due to the large flow of people and vehicles, the original construction of the city gate was a little narrow, so it was ready to be demolished and rebuilt.

Zhu Zhanji first asked the civil and military officials to inspect the city wall to be demolished, and then asked the Taoist priests of the Chemical Research Institute to install a total of 20 catties of picric acid explosives and more than 100 mercury thunderate detonators at the main nodes.

Twenty catties of explosives are just a small barrel, but the power of picric acid explosives is even greater than the famous TNT explosives in later generations.

After the 20 catties of explosives were detonated, a section of the towering city wall collapsed.

This scene shocked everyone and subverted the psychological illusion that they had always been.

The city wall is the bottom line of their psychological safety, but in fact, in ancient wars, only when the war of destroying the country is the time, it can play a huge role, and most of the time, the spies have already infiltrated and made the city wall useless.

Just like Zhu Di, if Li Jinglong hadn't opened the city gate, would he have been able to become the emperor smoothly? Not necessarily.

The city wall, which was as stable as Mount Tai in their minds, is now so vulnerable in the face of new explosives, does the city wall really work?

Being able to make these ministers reflect has actually achieved Zhu Zhanji's goal.

Even in later generations, after 20 years of reform and opening up, and after accepting so many external shocks, it was not until the new century that people's thinking changed.

Of course, Daming's propaganda ability is not as powerful as that of the ruling party, and Zhu Zhanji did not think of completely changing everyone at the beginning.

He did this only for another purpose, and that was to build a new city outside the city walls.

The cost of renovating an old city is much higher than that of building a new city on flat land. There will be no obstacle to the construction of a new city on flat land, whether it is the laying of sewers or the widening of roads at the beginning.

Moreover, these ancient cities have been built, although they are very backward, but they can still be preserved as future scenic spots.

Instead of dismantling, dismantling, dismantling, dismantling, as in the afterlife......

It is a pity that a country with an ancient civilization of several thousand years has few buildings that are more than 500 years old, which cannot but be said to be a kind of sadness.

This kind of cultural fault line is actually more terrible than the fault line of economic development.

It is only a matter of time before the economy has not developed and will continue to develop in the future.

However, once a cultural fault is formed, it will be more difficult to find it in the future, and it may not be successful.

The advent of muskets has completely changed the pattern of warfare in the entire East.

This is not the original history of only a few thousand, tens of thousands of muskets, craftsmen no more than 10,000.

Nowadays, the manufacture of muskets in the Ming Dynasty has formed a large-scale, institutionalized and standardized manner. Whoever is in power cannot ignore the role of the musket.

The former cavalry could storm several times their own infantry. But now, only the cavalry remained, and it was more mobile than the infantry.

Only cavalry with sabers, not to mention facing musketeers who were no less numerous than themselves, and even if the number of musketeers was half less, the cavalry was still not an opponent.

The pattern of war has changed, and even if there is a rebellion in the future, there is no resistance to the muskets.

Even if the alien race also has muskets, if they want to invade, it is impossible to have more people than the Ming Dynasty.

No matter how you look at it, today's Daming is already invincible, and Zhu Zhanji has this self-confidence.

Now, then, the city wall has indeed lost its proper meaning and has become more of a city decoration.

In the face of Zhu Zhanji's powerful persuasion of facts, the ministers adopted a plan for future urban construction on 15 July after half a month's deliberation.

In the future, the city will be built in different architectural styles according to the customs and climates of different regions.

And, most importantly, cities with different populations. The construction of sewers, water purification tanks, biogas digesters, have developed corresponding standards.

In addition, there are corresponding standards for the width of the road and the planting of greenery.

Zhu Zhanji does not expect every city to become a garden city, but he is absolutely unwilling to sacrifice the environment because of urban development.

Daming doesn't need to chase anyone, and there is no pressure to be chased, so it is enough to just develop in an orderly manner.

This construction strategy does not involve the renovation of the old city, let alone the city wall, but only provides a standard for the future construction of the Ming Dynasty.

The real urban transformation strategy will not formulate corresponding standards until after the transformation of Ying Tianfu and the accumulation of experience.

When the time entered August, the Ministry of Industry and the internal supervisor first started to build two ordinary people's communities on both sides of the road to the Jiajiang Industrial Zone outside the Qingliang Gate.

These two residential areas were built by the Ministry of Industry and the Internal Supervisor for ordinary people working in the Jiajiang Industrial Zone, and the standard for occupancy was to have a house in the inner city of Yingtianfu and to work in the workshop for more than a certain period of time.

The construction of the building of the patent department, others are just watching the excitement, but the construction of these two communities really made the people of the entire Yingtianfu boil.

The new house is a standardized five-storey unit building of later generations, but the difference is that it does not have the rigidity of Soviet-style architecture, but is more like the Forest Mansion of Singapore in the new century, but it cannot be compared in terms of materials.

According to the demographic structure of the Ming Dynasty, almost every house was a three-bedroom version, and then there was a large balcony, and each room had a glass window.

Then there is a separate kitchen and toilet, and you can solve the physiological problem without leaving the house.

Because the structure of the house is a bit stupid, it doesn't matter if you plant flowers and grass on the balcony, even if you plant trees.

And the greenery in the community strictly follows the standards, and there are small squares to play and chat.

On the roof of each building, above the load-bearing walls, there is a cement tank with paint to ensure water quality, and a special steam engine to provide water.

Such a house, not to mention in this era, even if it is pushed back a few hundred years, it will not be outdated!

It doesn't cost money to live in such a house, which makes ordinary people in Daming not crazy.
