In Dinghai, in the Ryukyus, and now in the Northeast, it is equivalent to restarting the process of urban construction, and even this time it is relatively difficult.

At that time, the Dinghai Navy was absolutely poor and white, but under the poverty and whiteness, it was only a 300-square-kilometer island, and under the terrible funds of the Dinghai Navy, it soon had signs of a big city, and then, a large number of people, especially the affected population of Lianghuai, they entered the Dinghai Navy in large numbers and became the foundation of the Dinghai Navy.

In this way, the Dinghai Navy also developed for two or three years, and then it developed to a considerable extent, and then it began to expand.

After the Jeongnavy was stabilized, first the Ryukyus, then Jeju Island, Hokkaido, and even Hainan, which was about to open, the territory of the Jeongnai Navy grew a lot, and the industry became more and more.

Unfortunately, these islands, the Ryukyus, are only more than 30,000 square kilometers of land, and Hokkaido is a little larger, much larger than the Ryukyus, but the distance is too far away, and there are problems in its own territory, so in this case, it is not suitable for large-scale development.

Together, these are tens of thousands of square kilometers at best, at most about 100,000, but this time, from Vladivostok to the Northeast, and then to Mongolia, there are almost 1 million square kilometers of land in the Northeast, and Inner and Outer Mongolia combined, almost 2.5 million square kilometers of land, a total of more than 3.5 million.

You must know that there are only so many of the current Northern Song Dynasty, and this is still the result of occupying Youyun.

When any of them, by his order of magnitude, reaches a certain level, the difficulty gets higher and higher

It is not difficult to occupy this territory, whether it is the Jurchens entrenched in the northeast, or Mongolia on the Mongolian steppe, they belong to the future, even if the army of the Northern Song Dynasty, if they can reach here at this time, they can also sweep them away, let alone the Dinghai.

The strength of the Dinghai Navy is far above the army of the Northern Song Dynasty, and it can quickly clean up these nomadic tribes and occupy these lands.

If there is no memory of the afterlife, occupy, even if it is his, but Zhao Xin is not, under countless historical experiences, those things that seem to be occupied, but not digested, are just like castles on the beach, they look beautiful, and once the big waves come, they will be washed away immediately.

Occupying, operating, the primary goal is the city, only the city can accommodate so many people, and then through the links of various cities, such a piece of land can be controlled.

Before landing in the northeast, the Dingjun Navy had already considered the overall layout in detail, although the city had not yet been established, but the approximate population needed was still known, and 12 million was a minimum number.

If a city accommodates 300,000 people, a minimum of 40 cities need to be built.

In fact, in the plan, about 80 cities will be built, of which one central city and 10 key cities will be established, and then other small and medium-sized cities.

This is different from in Vladivostok, Vladivostok and the Dinghai Navy are only a node, and, in winter, only the worst, or the coldest period of time, is very cold, not suitable for survival, but in the interior, this is much worse, a year's time, maybe only more than half a year, can build a city, which has a huge pressure on the Dinghai Navy.

A population of 12 million, almost all of the population, needs to be transferred from the Dinghai Navy, which requires too much capacity.

You must know that the distance between the sea of Japan and Vladivostok from the side of the Dinghai Navy may exceed 4,000 miles, which is very difficult to cross.

The navy is a large-scale immigration, and it is not like smuggling black slaves, so it can be completely ignored, and everyone must be given enough means of subsistence and construction, and arrange a back road, so that the number of people accommodated by the unit ships will be further reduced.

Even now, the Dinghai Navy relies on the shipbuilding industrial base, and the large-scale appearance of ships is still somewhat inadequate.

However, there is good news, that is, all kinds of lumber yards in the Northeast have begun to operate, all over the Northeast, all over the mountains, even if they need to be selected and processed, not every one of them is suitable for ship materials, but the huge quantity is enough to expand the shipbuilding capacity of the Dinghai Navy.

Dingjun, under the leadership of Zhao Xin, has already popularized all kinds of machinery in shipbuilding, and the improvement of sailing ships has been carried out, on the basis of the original Western-style sailing ships, adding a lot of oriental, and mechanical things, these things have been applied to these, further increasing the performance of sailboats, and sailboats that look similar, whether it is speed, or other aspects, have a huge and incomparable improvement.

The biggest lift is actually in speed, the basis of a sailboat is a dock, a dock, in a shipbuilding cycle, can only accommodate one ship, this is a basic theory.

However, coming out of later generations, segmentation, and the baptism of some other shipbuilding methods, Zhao Xin knows many schools, and may not know the detailed parts, but by reducing the time the ship is in the dock, the efficiency can be increased.

Make a list of the most important parts of the shipyard, and then reduce it by other means, and add other things like line engineering and co-ordination to the shipyard.

The larger the project, the more you can join the overall planning and merging, to a certain extent, the increase in efficiency is very terrible.

Dinghai, is in the continuous improvement of efficiency, gradually reduce costs, in order to achieve the purpose of increasing profits, this method, there is a limit, the highest, is the limit of productivity, that Dinghai has not touched, but the limit of raw materials has been touched.

Except for a small number of industries such as steel, raw materials are almost a large number of industries, and others have more or less encountered the problem of raw materials, among which the shipbuilding industry is the most prominent.

The shipbuilding industry has suffered a crisis of raw materials long before the large-scale expansion, and when the Dinghai Navy just opened the shipbuilding industry, because the Dinghai Navy did not have the accumulation of this aspect, some available ship materials, which took a considerable amount of time to complete.

In order to obtain enough ship materials, at that time, in addition to finding a way to manufacture them themselves, Dingjun waved money and made crazy purchases, which directly increased the price of ship materials many times at that time, which directly affected the shipbuilding industry in the entire Jiangnan.

Initially, this method could be used, but later, through research, drying room and a series of other treatment measures, the upgrading of ship materials was completed, from finished ship materials to wet wood, which allowed the crisis to be solved, and also gave birth to a huge shipbuilding base of the Dinghai Navy.

However, such a good day, that is, it has lasted for more than a year, and with the continuous method of determining the level of productivity of the navy, the efficiency of production is getting higher and higher, and now the raw materials are not enough.

In this era, ships are made of wood, even if the navy can use steel to replace some parts, so that the production of the ship is not so confined to huge trees, but a large ship with more than 10,000 materials, the demand for wood is very huge.

Two or three thousand tons of wood, converted, may be four or five thousand square meters, this is still a ship, and the demand for wood is almost limitless.

The Northern Song Dynasty is very large, the land is large, and the natural resources are abundant, so it is the most developed country on the whole earth in this era, but no matter how developed it is, it can't stand the Dinghai Sea with an industrial beast.

All kinds of ore are okay, as long as the navy is waving money, in order to increase revenue, the local government hires people to go down and dig it, but what about the timber.

The Northern Song Dynasty has developed for so long, in order to reclaim farmland, except for some mountains and forests, or in the primeval forests, most of the wood has been cut down.

The shortage of ship materials directly affected the Dinghai Navy, and the shipyards of the Dinghai Navy began to adjust, from the crazy expansion of production capacity to the limited, maximizing efficiency.

Even so, the supply of trees is decreasing every year, and the Dinghai Navy can buy minerals with money, as long as the minerals are not exhausted, spending money can always expand production capacity, but the Dinghai Navy can't, spending money to let the number grow against the sky.

In northern Siberia, various primeval forests in the alpine zone supplement this demand, and this primeval forest that has existed for hundreds of years or thousands of years, even if it is constantly cut down with the terrible consumption of the current fixed navy, it will not be used up in hundreds of years.

Not to mention, Zhao Xin, who came from later generations, is very aware of the point of sustainable development, cutting down a part, not to mention planting all of it, but planting a part, relying on these newly planted and a part of the natural restoration of trees, although it cannot be completely the same as before, but finally maintains a part of the forest.

With the Siberian wilderness, a large number of trees, even if not all of them are suitable for shipbuilding, but after these continuous transportation back to the Dinghai Navy, the shipbuilding industry of the Dinghai Navy has been able to operate at full capacity, and the number of shipbuilding completed every month has increased at least three times compared with before.

It has been suppressing production capacity, and began to burst out wildly, and finally the various ships of the Dinghai Navy appeared like dumplings, at most 2 years, and the total tonnage of the entire Dinghai Navy will be more than 3 times that of the present.

In itself, the Dinghai Navy has a total tonnage of more than 10 million materials level of water transportation power, and if it is tripled, it will be almost 40,000 materials, even if it is counted as tons, it will exceed 10 million tons, this number must not be regarded as less.

More than 10 million people, each occupies an average of one ton, or more, 3 years is enough to transport over, transportation is not a problem.

However, nothing exists in isolation, and the Jeonghae has already emigrated part of the population to the Ryukyus, Jeju Island, and Hokkaido, and on this basis, the population of the Jeonghae itself has been reduced to about 25 million.

This figure is still quite high, but if the population of the Ding Navy is reduced by another 12 million, it will become a problem, the population is not in the core position, on the one hand, it will affect the status of the Ding Navy, and on the other hand, the productivity will also have an impact.

Population is very important, as has been proven by later generations, and likewise in this era.

Take Liao as an example, at that time, when Yuan Hao attacked the grassland of Liao State, Liao State still had a million army, and in terms of military strength, Liao State lost very little, all kinds of weapons and equipment, and elite soldiers.

But under Yuan Hao's salary, he carried out a massacre on the grassland, which was going to kill him.

Millions of people, directly cut the Liao State in half, its own huge empire, not to mention falling apart, but also greatly affected, there is not enough population and resources to support a huge army, the Liao State army will decrease over time.

In the early stage of development, with the help of money and extremely high treatment, many people were given opportunities, attracting a large number of people, coupled with the growth as much as possible, the population of the Dinghai Navy reached 35 million.

This number is already the limit, and if there is more, the friction with the Northern Song Dynasty will inevitably rise by a notch, which is unbearable for the Dinghai Navy, which wants to develop slowly and lay a solid foundation.

If you can't make a move against the Northern Song Dynasty, then it will be impossible to increase the population on a large scale, and the 12 million population that is currently lacking in the Northeast will be part of the core force that can be drawn from the Dinghai Navy, and the other part can only be looked for.

In the entire Northern Song Dynasty, needless to say, the Liao State and the Western Xia, the Western Xia was almost wiped out, and Yuan Hao got a million million people to run to a place where the birds don't, which is not within the reach of the Dinghai Navy for the time being.

Liao is okay, there are still millions of people, but the navy can't do anything to Liao for the time being, unless Liao takes the initiative to provoke, this part of the population can be put first, as long as it does something to Liao, you can take it down.

In the two largest countries, under the premise that there is no way to obtain population, then the acquisition of population can only be placed on the other two countries.

The relationship between these two countries, at least in the present history, and China is complicated, and when China was strong, they attached themselves to China, became vassal states, learned from China, and attacked China when China was weak.

These two countries are Korea and Japan, which are deeply influenced by China and have always been representatives of learning from China.

In itself, the Ding Navy did not intend to attack them so quickly, the country is too small, but the current population gap, at the very least, should be supplemented by four or five million on the two of them.

This part will not be placed in the northeast, but it can be gradually filled to all parts of the Dinghai Navy to supplement the lack of population, and with enough population, the Dinghai Navy can speak of other things.
