I Build an Aircraft Carrier in the Ming Dynasty

The previous dynasties had a territorial limit, but Dahua no longer has this shackles.

At the beginning of the 18th year of Yongxing, the submarine cable project from Ireland in Europe to Quebec in North America was completed, connecting the communication network in the Americas with the Eurasian continent.

This means that Dahua’s telegraphs and telephones have touched all landmasses except Antarctica, enabling instant communication around the world.

If there is any abnormality anywhere in the world, the central government in Nanjing can quickly know it, unless the communication station is controlled.

However, the communication station is controlled, and the central government can also detect its abnormalities.

In short, today is different from the past, and it is much more difficult to rebel.

This is just one of the many benefits of instant messaging. The biggest benefit is that it facilitates the control and management of various places, and holds the decision-making power of major events in the hands, without the need to decentralize power.

At the same time, the central government's supervision over local governments has also been greatly strengthened, making it difficult for the situation to arise where the mountains are high and the emperor is far away.

The county magistrate who ruined his family, the prefect who exterminated his family.

In the past, local officials were really just like local emperors.

Even if they do various illegal things, not many people have the ability to go to the capital to report them.

Even if you go to report it, it is enough for the local officials to destroy the evidence.

Nowadays, supervisory agencies located in various places can report to the central government in the shortest possible time.

However, the telecommunications network in the Americas only connects important cities, and most places do not have electricity yet, and they are still under intensive construction.

In the Central Plains, the telecommunications network has almost covered the eastern and central regions.

If cities are divided according to tiers one to five, then all cities above the fourth tier have telephone connections, and every county has a telegraph.

The classification standards of Dahua cities are mainly measured comprehensively from two aspects: scale and economic development.

Roughly speaking, cities with a population of more than 5 million are the first tier, including Nanjing, Shanghai, Guangzhou, Wuhan, Tianjin, and Edo.

Those with a population of between 2 million and 5 million are second-tier cities, which are relatively large. There are many capitals of economically powerful provinces and famous overseas historical cities, such as Nanchang, Hangzhou, Hanoi, Delhi, Suzhou...

Those with a population between 1 million and 2 million are third-tier cities, and this one is even more.

Provincial capitals with less developed economies, prefecture-level cities in economically developed areas, some historical cities overseas, and population gathering places. For example, Xuzhou, Zhenjiang, Wuhu, Nagoya, Kagoshima, Seoul...

Those with a population between 300,000 and 1 million are fourth-tier cities, provincial capitals in some underdeveloped areas, ordinary counties and cities in the Central Plains, and population gathering areas.

For example, Tubo, Hami, Zhumadian, Shaoguan, Busan, Nagasaki, Haiphong, etc.

Most counties and cities with a population of less than 300,000 are classified as fifth-tier cities.

This is the rough division, but it is not absolute.

For example, Shenzhen, which is right next to Guangzhou, has a population of less than 2 million, but its economy is very developed and can be classified as a second-tier city.

Another example is Saigon, which has a population of more than 2 million. Because its economic development is average, it can only be classified as a third-tier city.

In Dahua, there are 40 second-tier and above cities.

In other countries, there are none in second-tier cities.

Paris and London, which are relatively prosperous, can only be regarded as third-tier cities according to Dahua's standards, and cannot even crack the top 40 in the world.

In fact, the current Dahua can basically represent the world.

If you make a ranking list of cities, population, economy, resources, weapons, etc., you will find that almost all of them are Dahua.

It gives the impression that Dahua is the only country on this planet.

For example, the box office list of Yongxing 17-year movies.

From the first place to the last place, they are all Chinese-language films, all shot in the Central Plains, and the directors and actors are almost all Chinese.

The French are famous for their romance, but without money, they cannot participate in the film industry, so they can only continue to introduce Dahua movies for entertainment.

In order to understand Dahua's movies, many people have to work harder to learn Chinese.

Another example is the ranking of global steel production companies.

From the first place to the last place, they are all Dahua companies, and they have nothing to do with other countries.

The longest railway ranking, the longest canal ranking, the largest power station ranking, the most powerful weapons ranking...

Whenever they see these rankings in newspapers, those foreign patriots want to tear up the newspapers and look miserable.

The Chinese people look at these rankings with great interest.

Even, they will not compare with foreign countries, but compare their own province with other provinces in Dahua.

Compared with foreign countries, your status is lowered.

In fact, foreign countries are not completely useless. Some of them could have been on the list, such as the list of famous scientists.

However, these people, without exception, all became Chinese at this time.

Without obtaining Dahua citizenship, they are not qualified to participate in the most advanced scientific research fields.

Therefore, no matter whether these scientists are happy or not, they can only join Dahua.

The only field where foreign countries had a chance to be on the list was ruthlessly stifled by Dahua.

Among these scientists who joined Dahua, many were celebrities from the original time and space.

For example, the mathematician Fermat who proposed Fermat's theorem was almost dying at this time in the original time and space, but because of the rapid development of Dahua's medical technology.

As a result, Mr. Fermat, who is now sixty-five years old, is still alive and kicking, and from time to time he can come up with a conjecture that makes people want to flatter him.

There is also the famous Boyle. In the original history, Boyle defined chemistry as a science and separated it from alchemy. He was the founder of modern chemistry.

But now, his achievements are not that high. Wu Changqing, the wise and powerful, omniscient and omniscient emperor of heaven, had long defined chemistry as a science.

However, gold always shines.

After Boyle learned more advanced chemical knowledge at Dahua, he is now researching more profound things. He is already exploring radioactive substances and stealing Madame Curie's job.

Others include Huygens, Hooke, and Newton.

Today, Newton is only 22 years old, but he is already showing his talents.

After the surrender of Great Britain, Newton was also taken to Nanjing.

Today, he studies issues of space and time.

There is no way. The laws of classical physics have been summarized by Wu Changqing. Without Newton, nothing will happen.

After Newton finished his university courses, his knowledge point had reached the principle of relativity and the principle of the unity of macro and micro.

In this regard, Wu Changqing has actually given a conclusion, even including the proof process.

However, because it is too esoteric, many people are confused after reading it. Only a small number of people are studying these theories and exploring the application of these theories in reality.
