Not to mention that overseas, those Chinese who are not willing to integrate into the Dinghai Navy are working hard in North America, and they have laid the foundation for Chinese in North America, although China did not carry out massacres in the Americas like the Western colonizers, but the plague still appeared in the Americas.

In later studies, it is a fact that there were no nomads in the Americas, and mankind began to establish bacteriology and made a deduction of plagues and infectious diseases throughout history.

Initially, this kind of infectious disease should have appeared in animals, but with contact with people, these bacteria gradually spread from animals to people, and after cross-mutation, then various infectious diseases appeared, plagues appeared, and even the terrible Black Death appeared.

At this point, the Indians have unique conditions, not only all kinds of crops are natural, the same, there is no animal husbandry, although it is said, the Indians also raise alpacas, but this alpaca is mainly to get the alpaca over, cut the hair and then throw it away, it doesn't matter, without these livestock, long-term contact with people, the resistance to bacteria is low.

In fact, this is also a topic of discussion on the Internet in later generations, saying that it is better to cross over, and it is better to say a little bit about soul wearing, what kind of concept will it be when you say that you are wearing.

Some people say that they will kill all sides, some people say that they will establish a dynasty, but some people say that if it is a real person who travels to ancient times, no matter what era, the germs carried by simple modern people can destroy the people of a country as long as they have the opportunity to spread.

This was evident in North America, and although the Dinghai did not throw the clothes and bedding infected with the plague and the Black Death into the tribes of the Indians, as the Spaniards did, once there was more contact with each other, and contacts began to increase, the contagion almost certainly affected these people.

In the face of this kind of plague that sweeps everything and keeps contagious, under the premise that there is no special medicine, what can work is only its own resistance, and the resistance of this Indian, in the face of these plagues, is like a paper paste, not actively infected, but only reduces the probability and speed of infection, at most it is to delay the time of the full epidemic, but once the time is enough, it is still necessary to spread the epidemic.

This is the road that the North American Indians will inevitably walk, if they can always survive so independently, everything is fine, but once someone lands on the North American continent, then a simple infectious disease can kill them, which is the inevitable result of long-term isolation and independent development.

Not to mention the development of North America thousands of miles away, everything is relatively smooth, almost perfect development, and the development of the Northern Song Dynasty has not been pulled down at all.

From the large-scale construction of railways and highways, the Northern Song Dynasty also began to work on bridges, in 1052, the first bridge through the Yellow River appeared, initially a railway bridge, and then all the way to the highway bridge and convenience bridge, in a short period of time, all over the Yellow River.

On the Yellow River, because the problem of large-scale shipping is not considered, as long as it does not affect the passage of small boats and passenger ships, the general railway bridges are not too high, the technical content is not high, and the width of the Yellow River is not wide.

The real test, in fact, is still on the Yangtze River Bridge, 8 years after the appearance of the bridge over the Yellow River, in 1064, on the Yangtze River, there was also 1 bridge.

This bridge, not in the middle and lower reaches of the Yangtze River, but in the vicinity of Wuhan, or in the west of Wuhan, does not affect the navigation of large ships, and is relatively close, compared with the Yellow River railway bridge, the technical content is a little higher, but it is a little higher.

After that, the Yangtze River Bridge was stagnant for a long time, until 6 years later, in 1070, there was a second one, this one is the most important Nanjing Yangtze River Bridge, this bridge, completely in accordance with the requirements of Zhao Xin, to ensure the passage of the entire Yangtze River waterway, did not choose the simplest pier, so that the distance between the pier and the pier is too close, is not conducive to the passage, choose the bridge pier on both sides, the structure of the cable-stayed in the middle, to ensure that there can be more than half of the channel, can guarantee the passage.

Just like breaking through some kind of barrier, once the technical problem is solved, on the Yangtze River, all kinds of bridges, began to appear continuously, two a year, about 5 years, it broke through 10, and continued to increase, the Yangtze River moat that plagued China in the past was overcome here.

Almost at the same time as the bridge, there is also a tunnel, the first large tunnel, the 500-meter-long Yaoshan Tunnel, also opened at the same time, with the tunnel, when the railway passes through the mountains, there is no large-scale detour, or a zigzag on the mountain, but directly through the tunnel, saving time and effort.

Tunnels are much simpler than bridges, when gunpowder appears, tunnels, has become possible, through a little bit, with explosives and the like, slowly blast away the rocks, maybe this is very dangerous, but through practice, research, and finally find a way, excavation and explosives combined, and then fill the support.

The first 500-meter tunnel took five years, but the second, 1,200-meter, took only two years, and then, along with the flowering on all sides, there are more than a dozen tunnels broken through almost every year.

In the great development stage of the Northern Song Dynasty, by this time, it began to be produced on a large scale, in the Liao country, because of the vast land and sparsely populated, coupled with a large number of grasslands and plains, there are not many tunnels that really need to be passed, and it is a big detour, and it is not much to spare.

But in the Northern Song Dynasty, there were many such things, the railways that used to bypass were straightened, and the big river that could not be passed, and also assumed that the railway bridge, the entire north of China, the original most elite part of the entire Chinese land, became a complete system, with the Central Plains as the center, the railway network of nine verticals and ten horizontals began to appear, and almost every state and county had a railway through, which was not a temporary solution before, but a real, thorough solution.

When the steam locomotive is put into operation and the train can travel at an average speed of 120 kilometers, the power of the whole of China will be combined, the control will increase, and the overall power will begin to increase.

24 hours a day, you can walk 5,000 miles, that is to say, the circle of one day has expanded to a range of 5,000 kilometers, it can be said that the entire most elite area of China is all in this system

The real connection of the railway is the backbone of the development of the whole China, the establishment of the industrial system, the convenience brought by various and its machines, so that China beyond this time and space.

Railways and highways, these are the development of the Ding Navy before, not to mention the newly built ones of the Northern Song Dynasty, in the original Liao State, it has been very developed, and the real letters that began in the Ding Navy are still in aviation, and a few years ago, the Ding Navy completed the development of aircraft, at the beginning, it was a military aircraft.

However, the military will be converted into civilian use, in the engine technology, as well as the development of special civilian aircraft, high-power engines began to appear, and after meeting the military use, civil aircraft began to appear.

The original aircraft can only carry about 8-10 people, in the twin-engine heavy aircraft, the development of the 900-horsepower engine is completed, the twin-engine is 1800 horsepower, such horsepower, in the bright heavy aircraft like the sea of stars, is nothing, but it is already much stronger than the first batch of passenger aircraft.

A total of 36 passengers can be carried, in later generations, I am afraid that it is not even as good as ordinary regional aircraft, but in this era, it is epoch-making and will be of great help to the whole country.

The maximum speed of the train is 140 kilometers, and it is not possible to travel at this speed all the time, and the average speed of most of them can reach 120 kilometers.

However, the speed of the aircraft, starting from about 250 kilometers, after special design, such as aerodynamics, and power improvement, the effect is even better.

The basic speed of the passenger aircraft has reached about 400 kilometers, and the maximum speed even exceeds 550 kilometers.

At three times the speed, the space distance is reduced by more than three times, and the space of 2,000 kilometers can take about 20 hours if you choose to travel by train, but if you take a plane, it can take up to 5 hours, which is about the same.

The reduction of speed by almost three or four times is equivalent to greatly increasing China's control, and also making communication over long distances more efficient.

The appearance of airplanes, for the Dinghai Navy, for the Northern Song Dynasty, is a huge promotion, not to mention the relationship of speed, simply one to fly into the sky, are how many people's wishes, although the price of air tickets is high, but the people who take the plane, also began to flow endlessly.

In itself, the Northern Song Dynasty in the 11th century was already the most prosperous and Johnson & Johnson in the whole world, but when this industrial system was added to the fast lane, the wealth created was even more considerable, and the value and income of China's people's labor force began to surge.

Originally, a city gate official in the Northern Song Dynasty could enjoy the treatment of European nobles and even the royal family, and now, it has risen to a higher level, according to statistics, by about 1070, the population of the Northern Song Dynasty expanded to 350 million, and the per capita GDP reached 12,400 guan, according to 6 percent of GDP, the per capita wage level even reached 7,000 guan, that is, about 600 guan a month.

In the past, dozens of cows could be bought, but it was the salary income of ordinary people, and it also represented China's wealth.

All over the country, from the cold to the tropics, the entire northern hemisphere has very diverse climatic conditions, and in this case, the output is also very diverse.

After solving the problem of food and clothing, diversification has become the key, Zhao Xin is not under the overall planning, but he knows that it is enough to solve the problem of abundance and diversity, the insurance base of food in the past, plus more methods now, so that many big cities, can eat fruits from all aspects anytime and anywhere, from the deep sea to the big guys up the sea, all kinds of nets to breed up a variety of fish, these enrich the market,

In order to strengthen control, especially over the whole of China, and to ensure that the distance to all places within the whole of China is about the same, the place located at the junction of Hubei and Henan was chosen as the new country.

After the selection of the system, taking into account the former royal city, Chang'an Luoyang and the former Bianliang of the Northern Song Dynasty, after many comparisons, considering the huge size of the south, the final location was determined to the south, and the feng shui and foundation were selected to be relatively good Nanyang.

Nanyang is located in the basin, this former imperial township, Liu Xiu's hometown, in this era, began to radiate light, a large number of railways to here, as well as the construction of the airport, in order to determine the construction capacity of the navy, it took 10 years to complete the construction of the new country, the same, also began to determine the 4 Beijing.

In this dynasty where the Northern Song Dynasty is located, it has become customary to have more Kyoto, the Northern Song Dynasty has four capitals, the Liao State has five capitals, and the four capitals of the Northern Song Dynasty are almost in a very narrow area, and the distance between them is not very far, they are more in name and level.

But China is too big, at present, in East Asia, there are more than 20 million square kilometers of land, in the north, after Inner Mongolia, a large area of wasteland and no man's land, only a few core cities under the jurisdiction, but in the south, the population is relatively dense.

There will be more and more people, not to mention the Alpine regions of Siberia, where the population grows slowly and is not suitable for a large number of densely populated areas, but in the south, in the newly opened lands, once the population grows, it will become dense.

The administrative divisions at the provincial level can be strengthened, but some of the capitals can still play the role of jurisdiction and commander, and a total of six Kyotos have been set up.

In addition to the capital Nanyang, the north and northeast, of course, are Shenyang, the location is slightly unsuitable, but it already has a foundation, or the country where the navy started, there are natural conditions.

Shenyang, which mainly governs the northeast, the Bohai Bay, and part of Inner Mongolia and Outer Mongolia, is surrounded by the most elite industrial area of the Dinghai Navy, which is also called Beijing.

Xijing itself was intended to be located in Xingqing Prefecture, but later, it was found that Xingqing Mansion could not play the role of commanding the entire west and north, so it was adjusted and placed near Urumqi, which was also a good area, radiating around, mainly the northwest on the original territory, and at the same time, it also had jurisdiction over Lake Baikal and Siberia.

Nanjing, not in the later Nanjing, but in Hainan, the southernmost province of China, in this era, is not the southernmost point, although it is an island, but through a strong transport fleet, can radiate the entire Southeast Asia, so, is called Nanjing.

Tokyo is located in Nanjing, which has jurisdiction over the southeast coast and the Yangtze River basin, especially the Yangtze River basin, which will become the highest industrial area in China in the future once the Yangtze River waterway and other supporting facilities are completed.
