After 25 million people, in fact, there is no longer a shortage of manpower, there are basic manpower in all aspects, at most it is a question of speed and slowness, and there is no problem of whether there is anything or not, what is lacking is territory.

Territory represents security, even if the Dinghai Navy has an invincible fleet, but the people of the Dinghai Navy who have not experienced the war may not understand how good the safety of the island is, and the huge territory is the strength of the country, which is the cognition of ordinary people in this era.

There is no harm in expanding the territory, even from the perspective of later generations, the territory, on the one hand, represents the depth of the strategy, and on the other hand, represents the resources.

Dinghai is only a 300-square-kilometer island, even if you get the Ryukyus, the Ryukyus in later generations will be called the treasure island, but this treasure island is more in a political sense, and the real mineral deposits and products are not very many.

If the navy develops rapidly, the two islands will not be able to support it at all, and the huge demand of the navy will be determined.

After two or three years of changes, especially the rapid development of the Dinghai Navy, science and technology have been basically laid, and the foundation for industrialization has also been laid.

For resources, there is never too much, so expansion becomes an inevitable choice.

Many middle-level people, their mentality is the same, they all believe that expansion is imperative, but in the choice of expansion, there are two plans, and they are arguing with each other.

In the middle, because of Zhao Xin's opposition, directly attacking the Northern Song Dynasty was vetoed, even if the Dinghai Navy had 25 million people, it could not provoke the Northern Song Dynasty, the Northern Song Dynasty was too big, the population was large, once the war with the Northern Song Dynasty started, perhaps the strength of the Dinghai Navy's army was very strong, and it could easily defeat the forbidden army of the Northern Song Dynasty, but what about the people's will and popularity, these are all problems.

Zhao Xin objected, and others also seriously considered it, and also felt that at this moment, it was not the right time to enter the Northern Song Dynasty, so aside from the territory of the Northern Song Dynasty, there were only two other plans that could be done.

One is to the south, with Hainan as a springboard, directly attack Southeast Asia, and obtain a large area of Southeast Asia, which is the influence of the Chinese cultural circle, they themselves have no history and culture, and most of them are some Chinese who come here, staying to inherit, otherwise, the native people are still in a primitive society.

Of course, more support is still to the north, if it was before, the navy was set to the north, but I just know that there are Liao countries and nomads in the north, but these nomads and Liao countries, what kind of position they are in, I don't know this.

Even when it was not done, the Dinghai Navy also strengthened the investigation, and still understood the general situation in the north.

If you can't borrow the road from the Northern Song Dynasty, let alone from the Liao State, then there is only one way by sea, and it seems that the sea route is very long, and there is no problem for the Ding Navy.

Through whaling and fishing, and by the way, simple trade, in a year or two, has been given to the navy, the surrounding charts have been drawn, not traditional, the kind of simple charts, is integrated with latitude and longitude, more accurate charts, and even some important ports, including hydrological features and waterways, these, can ensure that most of the ships can enter the port around the clock.

It was such charts that made it possible to move north.

People will change, perhaps for Zhao Xin, as long as the Northern Song Dynasty develops well and he develops well, other things can be ignored.

For these subordinates of the Dinghai Navy, they need to have a goal to strive for, a force that has a greater wealth than the Northern Song Dynasty, and similarly, a powerful military force, if you say that you don't expand, you won't expand.

If they really expand to a certain extent, even if they can't establish a dynasty in the Northern Song Dynasty, maybe they can be in the north, in the land of nomads, or even in the Liao dynasty, then they can become the founding fathers.

These future expectations are always the biggest promoter, and when many middle-level people began to discuss and tell this, Zhao Xin was helpless when he heard it, vetoed them, continued to dig deep holes, and accumulated grain, didn't that chill the hearts of these people?

Zhao Xin was reluctant to attack directly from the Dinghai Navy and meet with the Northern Song Dynasty soldiers, at least, there were parents, Renzong and the concubine, no matter what, it was not bad for him, and the previous thing was also he took the initiative to jump away, otherwise, it would be impossible for Renzong to give up such a biological heir to the throne.

In the same way, these heroes of the Dinghai Navy also analyzed as much as possible, if they landed directly from Haizhou, the final effect would finally negate such a practice, and landing from Haizhou would indeed be useful at the beginning, after all, the elite of the Dinghai Navy would still attack Haizhou, which was undefended.

Even taking advantage of the strength of the army, it may not be impossible to capture the Huainan East Road and the West Road.

But what about after that?

From Haizhou to the variable, it is at least 700 kilometers, and there are many important towns in between, and now, many fortresses have been built.

Although the Ding Navy had already made artillery, it was more than 10 inches of heavy artillery, and these guns were installed on the battleship, and with the battleship, they could move quickly, but when they reached the land.

The Dinghai Navy has built roads as much as possible, but there are not many cement roads, at most they are stone roads, and these roads cannot pass such a huge artillery.

In the construction of the army, Zhao Xin will also give artillery, but because of the relationship between steel and various production constraints, the real small artillery can only choose copper cannons, which are not only heavier, but also less powerful.

In such an era of cold weapons, the fortifications that are integrated into the fortress may be a little outdated in the era of hot weapons, but they are not easy to capture.

A large amount of land is very important for the Dinghai Navy, and it is better to go north than to choose the Northern Song Dynasty.

In the northern Liao country, there are also various ethnic minorities, although they are vast and sparsely populated, but the population is still quite large.

For the Northern Song Dynasty, whether it was slaughtered or enslaved, this was more or less problematic, but for these ethnic minorities, it didn't matter.

Perhaps, because of the lack of manpower, Zhao Xin will not use exterminating slaughter against them, enslavement is indispensable, after several generations, this part of the enslaved will gradually integrate into the Han nation, which may be an alternative integration.

In Zhao Xin's heart, there is no such thing as a concept of a great China, from the perspective of the whole of Siberia, Zhao Xin wants to continue to follow the distant territory, which can be regarded as an expansion of China, on the basis of the original Chinese territory, and then occupy a large territory, a bigger China, will rise in East Asia.

Similarly, don't look at it now, the Northern Song Dynasty has defeated the Liao State and taken Youyun, it seems that it should have crossed the Liao State and become the first power in East Asia, but in fact, the Northern Song Dynasty, from the ministers to the people, and even in the heart of Renzong, did not have the consciousness to completely overwhelm the Liao State.

This point, from the occupation of Youzhou, take the initiative to stop, build a variety of fortresses, passive defense can be seen, after gaining a firm foothold in the future, choose to attack Yunzhou, which is close at hand, and will not choose, go straight to Zhongjing and Tokyo of Liao, and take the most important land of Liao.

At that time, when Zhao Xin took down all the land around the Northern Song Dynasty, and showed his muscles, maybe he could get it smoothly in the face of huge pressure.

The South, though more readily available, according to information from the recovered pirates, the southern islands, which are mostly grassy and well-populated, are fragmented and do not have a strong state.

Not to mention that the Dinghai Navy poured all its troops over, even if it mobilized one or two thousand troops, it would be enough to take it.

The only thing to worry about is miasma and infectious diseases.

Of course, Zhao Xin knows that in the fact that there are many plants and no one is under the influence of people, the natural primeval forest is so terrifying, and the animals are secondary, and the parasites and those miasma are the key.

Without generations of slash-and-burn farming, it is really not difficult to adapt to the situation in Southeast Asia.

Zhao Xin didn't want these armies he had carefully cultivated to be defeated either by the hands of the enemy, but by these miasma and infectious diseases.

Without professional bacteriological and toxicological research, it is quite dangerous to set foot on the soil of Southeast Asia.

On the contrary, in the north, there is no other problem except for the cold, the climate is moderate, and there is no infectious disease, as long as the nomads and the Liao country are defeated, this vast land is theirs.

Cold, there are cotton clothes and duck down coats, these have replaced fur, become the warmest winter clothes in winter, once caravans wore them, in winter, to the northern high latitudes, the effect is very good.

Although the army is a little troublesome, it is still possible to prepare in advance.

Solving the problem of cold, the biggest problem is only Liao.

Even if the Liao State was attacked by the Western Xia and the Northern Song Dynasty successively, and lost most of its population and clouds, it was still a very powerful empire.

Up to now, the Liao State still maintains more than 600,000 cavalry, and the number and power of the cavalry are worthy of being the first in Asia.

Even if a thermal weapon is formed, in a place where there is no danger to defend, in the face of the impact of a large number of cavalry, it may be able to kill and injure a large number of enemies, but the final result may not be victory.

On the road to the rise of the Dinghai Navy, it will not withstand twists and turns, and it may be successful to directly target the Liao State, but it is more likely to be a big fight, such a result is not what Zhao Xin wants to see.

Maybe if you change to an iron-blooded superior, you can directly replace the Liao State for the purpose of defeating the Liao State, and the entire north will be in the bag, as for how many people will die when it is taken, it is not for him to consider.

Zhao Xin is not such a person, the same, the Liao and Song Dynasty are too close, under his suggestion, the Imperial City Division has developed vigorously in the Liao State, and under the premise of having money and people, many things in the Liao State cannot be hidden, and the Dinghai Navy wantonly attacked the Liao State, which was noticed by the Northern Song Dynasty, and everything that followed was much more difficult.

Then crossing the sea and land, bypassing Korea, landing from the other side, attacking from the white mountains and black waters, and then taking the lands of the nomads, this became the preliminary plan.

After many considerations, especially Zhao Xin's decision, the final plan, the core of which is to go north, and the goal of going north has been unanimously recognized by many people, and a careful plan has been formulated, which soon began.

At this moment, the Dinghai Navy is no longer the original, a projectile land, 300 square kilometers of land, creating a terrifying industrial civilization, and under this industrial civilization, funds and materials are readily available.

At the end of the sixth year of Gyeongli, the Jeongjun Navy sent 24 warships, 12 of which were first-class battleships, plus more than 40 transport ships, transporting almost 20,000 soldiers, to Jeju Island in the north, and it took three days to occupy Jeju Island.

This island, which has only a small number of natives, is much smaller than the Ryukyus, but it can be used as a springboard, an important point on the shipping lane, and then Hokkaido.

This island, which even Japan did not realize and did not develop, not only has a huge territory, but also is rich in resources, and compared with the battle of Jeju Island, this battle used more military power, and almost all the navy and army poured out.

Hokkaido, of course, was taken by the Navy, as the world's largest islands, although Hokkaido is relatively cold, but the area is not small at all, the most important thing is that there is a lot of land that can be developed, and there are a lot of resources, the most important thing is the Hokkaido fishing grounds.

At present, the Dinghai Navy also has at least a fleet of more than 200 ships active in Hokkaido, and a supply base has also been built in Hokkaido, which is the closest to the fishing grounds, but this supply is not the same as the real occupation, once Hokkaido is occupied, the Dinghai Navy will not only have a complete foundation on the road to the north, but also have a larger resource base.

In the summer of about the seventh year of Keireki, the navy and army made a large-scale sortie, occupied Hokkaido, captured about 200,000 natives, and opened several ports and cities in Hokkaido, and began large-scale migration.

Otherwise, if you simply capture an island, with the current military strength of the navy, send some warships and land forces to easily take it, but this capture is not equivalent to occupying it, let alone being included in the system of the navy.

Time waits for no one, the speed of immigration and construction is very fast, Jeju Island, by the end of the seventh year of Gyeongli, has about 3 million people, a year's time, too many immigrants, Hokkaido is a little bit worse, about 1 million people, after establishing a solid foundation, the Dinghai continued to go north,

In the summer of the seventh year of Qingli, he landed in Vladivostok, and finally crossed several springboards and islands, and set foot on land, which is almost more than 2,000 kilometers away from Youzhou, which is currently occupied by the Northern Song Dynasty, that is, from nearly 5,000 miles, which is almost insurmountable for many people in the Northern Song Dynasty.

It can be said that landing here will not attract anyone's attention at all, not to mention the Northern Song Dynasty and the Liao Kingdom, even the nomads who are close at hand will not find it.
