Australia's affairs will be gradually promoted, this will be carried out together with the development of Southeast Asia and the exploration of the Pacific, which will be handed over to the exploration fleet and the garrisons in Southeast Asia to complete, and the final foundation of the navy is still in China, of course, the territory occupied by the navy at present.

In the future, when the map of the world is opened, it is really better, it is worth developing, and there are not many lands with huge empires, and China is one of the best, otherwise, China will not have been leading the world for more than 2,000 years.

China's misfortune lies in the Ming Dynasty, which started with European navigation, but did not develop in the right direction, and at the same time, the entire court did not support it, lost more than 200 years, and arrived in the Manchu Dynasty, it goes without saying that it was a huge regression for the Ming Dynasty, not to mention the progress of the whole world.

In this world, let's not talk about Zhao Xin, let's just say that there is no navy, as long as the nomads are solved and the cement and fortress are handed over to the Northern Song Dynasty in advance, it is impossible for the nomads to enter the Central Plains.

You must know that in the era of the rise of Mongolia, Eurasia, no matter which country or which nation, will be influenced and killed by the Mongols, and the Mongols do not know how many countries they have perished, but they suffered a big loss in the Southern Song Dynasty, and if they did not get the return cannon in Central Asia, he would not have conquered the Southern Song Dynasty.

The return cannon is very powerful, for the defense of the city wall of the Northern Song Dynasty, there is a huge lethality, but on the cement and the fortress, sorry, non-gunpowder weapons, if you want to deal with the reinforced concrete structure, it is almost impossible to complete the task at that time, for example, with artificial, with a hammer can dismantle the wall, but this demolition, is an ordinary brick wall, a load-bearing wall composed of reinforced concrete structure, that is almost not a hammer can deal with, with a hammer to beat for a long time, maybe, just a little damage.

Even the sledgehammer is like this, and the stones thrown back from the cannon can have as much lethality, and the most is a little damaged, maybe hundreds, thousands of times, and it will only cause damage when it hits the same place.

Not to mention, the fortress is concentrated in the era of cold weapons, the defense of the masterpiece, almost every place, every corner, is designed for war, the more to win less, to the extreme, not only a little blow, but also a surface strike, and even a space strike, as long as you enter the attack range of the fortress, the fortress can flexibly use the advantages of multiple people, as well as the advantages of long-range and layout, such a defense capability is great.

The fortress defended by 500 people, as long as all kinds of resources are abundant, can block 10,000 people, or even more, until now, the entire Northern Song Dynasty has designed so many fortresses, and there is no one that has been forcibly captured, this is the strength of the fortress.

Compared with the Northern Song Dynasty, the Dinghai is stronger, the fortress is only the basic equipment, the key is the thermal weapon, after the emergence of thermal weapons, quickly crossed the original class, began to develop by leaps and bounds, when the emergence of metal fixed ammunition, the level of thermal weapons of the Dinghai Navy, has not been lower than the level of the end of the 19th century and the beginning of the 20th century, if you add the advantages of artillery and machine guns, the Dinghai is equal to the 11th century, mastered at least the combat effectiveness of the mid-to-late 19th century, and is absolutely powerful.

The advent of thermal weapons defeated the superiority of Mongolia, and this is true in the East and the West, otherwise, the combination of the Mongols in the era of cold weapons and the Mongolian horses is incomprehensible.

The Mongols have terrible riding skills, and have the ability to endure hardships and stand hard work, the horses of the Mongolian cavalry are mares, not only more tenacious than the stallions, at the same time, as long as there is grass, you can produce mare's milk, you can quench your thirst, this is the basis for the Mongols to rely on the cavalry to sweep the world, because he almost does not have to carry any logistics, a team of tens of thousands of people can set off.

In the era of cold weapons, cavalry is a strategic type of troops, and only cavalry can deal with cavalry, and even for Mongolian cavalry such a cavalry ranger, heavy cavalry is not an opponent, whether it is the heavy cavalry of the Jin Kingdom, the heavy cavalry of Western Xia, or the knights of Europe, they were all defeated under the Mongolian cavalry, the reason is very simple, the Mongolian cavalry, the mobility and lethality to the extreme, in the era of cold weapons, is the best type of troops.

But in the era of thermal weapons, even the most elementary thermal weapons, can solve all this, the Mongolian cavalry has not yet approached, long-range muskets, can easily penetrate the thin armor of the Mongols, if you add heavy armor, Mongolian horses can not bear, under the restraint of the troops, the Mongolian cavalry was quickly defeated, retreated to the steppe of northern China, until the rise of another nomadic people.

The advance development of thermal weapons, coupled with the fortress and cement, as long as these are not completely lost, the Mongols will never be able to break into China, let alone the current Dinghai, which has developed on a super-scale scale.

The development of the Dinghai Navy has always been leapfrogging, even if it is a year there are huge changes, not to mention two or three years, from the beginning of the exploration of the Americas, to the present, the basic stability of the Americas, and the Mayans have done a war, the time has gone through 3 years, close to 4 years, in the 4 years, the Dinghai has achieved tremendous development.

In the past 4 years, Zhao kept his promise, maintained restraint in his relationship with the Northern Song Dynasty, and did not have such large-scale immigration as before, which almost shook the foundation of the Northern Song Dynasty, but the reputation of the Ding Navy and the inextricable connection with the Northern Song Dynasty still made the Ding Navy very attractive.

One after another, thanks to this attraction, there are still millions of immigrants every year.

There is no way to do this, the Northern Song Dynasty has such a wide territory, and there are many communication channels between the Ding Navy, and there are many communication channels between the Ding Navy, just three railways, there is no way, even if the Northern Song Dynasty knows some information and carries out some restrictions, but I don't know how many people have escaped these restrictions, not to mention the cooperation of the Ding Navy, even if there is no cooperation of the Ding Navy, it is not easy for the Northern Song Dynasty to find out if they simply run away by themselves.

Not to mention, in addition to the railway passage, there is also water transportation, water transportation extending in all directions, almost the entire Northern Song Dynasty into a sieve, as long as the slightest negligence, it is one or two boats of people, for an ordinary ship of 800 materials, that is hundreds of thousands of people.

Unless the Northern Song Dynasty can adjust its policies and strengthen the people's sense of happiness and belonging, otherwise, between the Northern Song Dynasty and the Dinghai Navy, which has developed transportation, it is absolutely impossible to isolate this.

Millions, it is already restrained, of course, the continuous loss, the Northern Song Dynasty also discovered, there is no way, if you want to stop them, you need to pay too much price, and for the Northern Song Dynasty, millions, it is also within the range of bearability, because the financial situation of the Northern Song Dynasty has improved, coupled with a large number of farmland and water conservancy construction, as well as a large-scale increase in grain, so that the Northern Song Dynasty is enough to feed more people.

The same land, higher yield, itself, under such a premise, the Northern Song Dynasty expanded the population doubled, can bear, and now it has doubled, reaching about 55 million, compared with the peak, at least nearly 6 percent, it seems that the population has decreased, but with the support of various equipment of the Dinghai Navy, under the popularization of some advanced crops, more grain has been produced.

In this case, on the contrary, some land annexation has been delayed, and for places with less land and more people, it is possible to work, nearly 100 large and small factories, each of which can accommodate 2,000 people, and eventually needs more than 200,000 people, which is a terrible situation.

This is the profit generated by industry, under the premise of a large number of population dispersion, the financial revenue of the Northern Song Dynasty, not only decreased, but gradually increased, such a sunny situation, or affected the entire Northern Song Dynasty, to a certain extent, the center of the Northern Song Dynasty, ignoring the consequences of a large number of population losses, using a blind eye strategy.

4 years, for the Northern Song Dynasty, may be an eye-catching time, for Renzong, for Han Qi, the same, even in their feelings, the development of the Northern Song Dynasty has been very terrible, from 25 million yuan of annual income, to nearly 500 million now, there is an annual growth of more than 5%, which means that the annual growth is the income of the previous year, and the Northern Song Dynasty has developed very well in all aspects.

However, for Dingjun, it has been four years of great development of industrialization, and this development is in all aspects, and the most important development is population.

There has never been a regime that has such a desire for population as the Dingjun, a feudal society, a small population, a large population, that is the problem, land annexation, famine, and eventually unrest and peasant army uprising.

However, in an industrialized society, population represents labor and wealth, which is the inevitable way of development of industrial society.

The population of the Dinghai Navy has been growing continuously since the establishment of the Dinghai Navy, but this growth has grown at a certain rate, from the very beginning to hundreds of thousands, one or two million, with the rapid development of the Dinghai Navy, the growth has been very fast.

In the beginning, only adults arrived, to the back, the elderly, children gradually arrived, the former, must be respected, to the Dinghai is a blessed existence, they can do nothing, just let the Dinghai raise it, but the latter, the same is surrender, but yes, they are not only like this, but also join the school, to learn.

The Northern Song Dynasty, which may be the entire feudal dynasty, has the deepest understanding of learning and culture, and is also a dynasty with the best treatment.

There is an opportunity to learn, or free, even if it is poor and can't open the pot, they are willing, not to mention, in Dinghai, you can easily earn money, it is precisely because of a series of comparative understanding of Dinghai that these people are willing to let their children learn, learning is the way out, this is not mentioned in the propaganda, or really done, Ding Haijun does not need the imperial examination, as long as he is capable, he will be recognized and valued, this is it

The key to learning, a person who is illiterate is just the most ordinary worker, but the literate and according to a certain degree of learning, promotion, is the most needed worker, the higher their strength, the greater the contribution to the factory and production line.

From the beginning of Zhao Xin's arrival in Dinghai, he was committed to building a reasonable education system, and even did not hesitate to drive away an old scholar who had contributed to Dinghai, at that time, this old pedant, plus his disciples and grandchildren, almost occupied most of the educational resources of Dinghai, perhaps, if a bad response, the entire Dinghai education system will collapse.

But this person didn't want to go, because what he insisted on was the theory of the Northern Song Dynasty imperial examination, and he vetoed other similar technicians and similar vocational education, which caused huge problems at that time, and even got Zhao Xin's attention.

The initial popularity, under the premise that there are not enough teachers, Zhao Xin can use these masters, because there is no choice, but once some things are normalized, then there is no need for these people, if these people who are easy to cultivate are led astray by these masters, it will be a huge harm to the Dingjun.

This is also the fundamental reason why Zhao Xin still decided to clean them up at that time, cleaned them up, and had a labor pain on the Ding Navy, however, there were people who valued the future of the Ding Navy and were willing to do it according to the training methods of the Ding Navy, and in the end, Zhao Xin survived and built an education system with general education, technical education, and university education as the core under his leadership

This education system, advanced, that has passed the test of later generations, and in terms of practicality, it is also very suitable for the use of the Dinghai Navy, which has led to the current result, and the Dinghai Navy has formed a very perfect professional system.

Even if you don't know anything, you can also learn to form quickly in school, and some older children, after 2-3 years of surprise study, plus later, night school, and other training, can also stand out, but these are not talents, but a sufficient, can become qualified workers on the assembly line.

In the beginning, Dinghai did this, and relying on this method, a large number of qualified workers were trained, which played a very important role in the development of Dingjun.

However, such qualified workers cannot support the Dinghai Navy in a more in-depth direction, simple technical work, with the help of machines, according to fixed procedures, to produce enough products, to create wealth for the Dinghai Navy, but if you want to study and promote the scientific and technological development of the Dinghai Navy, it will not work, that needs professional personnel.

At the beginning, Dingjun definitely can't be considered, although in the layout from the initial elementary school learning, but this is the mainstream, the rapid technical education is, but with the increase in the time of the establishment of Dingjun, after two or three years, when the labor force is not so much pressure, normal primary school, junior high school, high school and university education, has become the mainstream.
