Heavy industry will always be the most powerful industry, and after the heavy industry has been determined, the center of the navy has also been determined, and large-scale construction has begun.

As for farmland, under the premise of ensuring survival, the role of farmland is almost very weak, and instead of building farmland on a large scale, it is better to build a city and build industry on a large scale, and as long as the industry goes up, the rest will not be a problem.

At present, the Dinghai Navy has built an urban agglomeration of 8 cities with Suihua as the center, and this urban agglomeration is almost in the same or similar dimension, extending from Vladivostok, almost 250 to 300 kilometers or so, and a city will appear.

These cities, in terms of location, are not the most suitable locations, after all, they are not the central cities that have been selected by history, nor are they some surrounding agricultural core cities, but various cities built for distance and industry, which have certain problems.

However, for the poor and white Northeast, there will be no problems for the time being, and if the population is increased and the transportation is developed, the problem will be relocated.

These cities are large-scale cities, at least, the area of the entire city will exceed 40 square kilometers, for the time being, just planning an indoor construction, but on the basis of the Dinghai Navy, it is very huge, just a few months, it shows the prototype.

Each city, can accommodate a population of 300,000, between each other, there is a highway connection, in the future, when the steel plant of the Dinghai Navy appears in the northeast, the steel industry, will become an important foundation, the railway will also appear.

It's still a little early to talk about the railway, because the railway consumes too much steel, although the construction of the foundation, the construction of the city is also needed, but some not so high buildings, can also be replaced by others, but the railway is not good, it must be iron, and it is quite high quality, the specification is relatively high steel.

However, after the construction of four 500,000-ton steel mills around Suihua, with an annual output of more than 2 million tons, it can already support the construction of railways in Northeast China.

A city, a road, and even a series of fortresses, the speed of the construction of the fortress in the Northern Song Dynasty has been relatively fast, the Ding Navy is the founder of the fortress, his construction speed is even faster, to put it bluntly, in one year, to be exact, from March, the huge construction army of the Ding Navy, a total of more than 300 fortresses, is a preliminary of the entire occupied territory, to include it, at this time, even if the Liao State comes to attack again, there is no fear.

It's just that 20,000 troops were annihilated, and the Liao State has not come to attack, which is very strange, is it possible, the Liao State really endured it.

Endure it or not, Ding Navy does not know, and does not plan to know, as long as he stabilizes the land, there is a buffer of one or two years, when the immigration is in place, from 5 million in the eighth year of Qingli, to 12 million in nine years, 2 years, to complete all the immigration, and initially build an urban agglomeration with more than 30 large and small cities as the core, and then lay a solid foundation, from all sides to supplement the population frantically, and strive for 5 years, the land area of Liaodong exceeds 4 million square kilometers, and the total number of people reaches about 18 million. It basically occupies such a large area.

Liaoguo really endured it, the consumption of 20,000 yuan is really an unbearable loss for Liao, but this loss, for the current Liaoguo, can only endure it.

Because, the loss of 20,000 people is too fast, when 20,000 people attack the team of 2,000 people, and everyone thinks that they will be able to win, those weapons that can make a loud noise and attack from a distance, and those weapons that look a little like sticks, but can attack cavalry from a distance, even the knights in full armor can be pierced at once, and the power of this weapon is really too great.

They don't know where these people come from, but as long as there are 10,000 people in this part, then it is not something that the current Liao State can deal with.

In the past two years, the strength of the Liao State has declined greatly, losing the grassland, the huge ethnic group, and the loss of Youyun, the former is the source of soldiers and population, and it is also the basic plate of the Liao State, with these populations, many things in the Liao State can be done, such as conscription, such as rewards and food.

However, without these, the basic soldiers of the Liao State were reduced on a large scale, although it was not visible at the beginning, but after that, a large number of reductions, and by now, the standing army of the entire Liao State has dropped to about 400,000.

Now, even if it is 400,000, there is no way to maintain it, there is no way, the output of grain and meat in the Liao State is insufficient, and even the officials and nobles in the center are saving expenses and gradually reducing the consumption in all aspects to ensure that they can survive, and the army is even more so.

Compared with the population, the loss of Youyun seems to be inconspicuous, after all, in the territory of the Liao State, Youyun's status is not high, it is a place where the Han people are concentrated, and it is naturally incomparable with the nomadic tribes, but if he loses it, he not only loses a huge source of food, but also loses the iron from the Han people.

The latter is the most important, it turns out that maintaining a heavy cavalry of hundreds of thousands of people not only requires a large amount of armor, but also daily updates, builds, and repairs, which all need to be carried out by people.

The loss of Youyun, although there are still some blacksmiths in Liao, but the lack of the lowest and most basic has made the production of heavy cavalry armor in Liao State drop by 9%, and at the same time, all kinds of repairs, damages, and even maintenance have also been greatly reduced.

Now, the 400,000 army, it stands to reason, should all be heavy cavalry, but in fact, the number of heavy cavalry has been reduced to about 250,000, and at a rate of 30,000 per year, it is rapidly decreasing.

The army of 20,000 was annihilated, which was a big deal for the Liao State, but they had no way to react, there was no food, no money, and even the state of the army was not good.

I'm afraid that even the Ding Navy didn't expect that the Liao State, which has always been strong, will be so cowardly after it weakens, of course, the controversy in the court of the Liao State is still very fierce, some old nobles, still immersed in the state of the Great Liao State, want to crusade against these unsubordinate, but those ordinary civil officials, realizing this, think that what should be done now for the Liao State is to consolidate.

On the one hand, consolidate the original territory, concentrate the Han people as much as possible, provide them with better conditions, let them re-smelt and cultivate, and there are fewer clouds, which is not terrible, in the surroundings of Tokyo and Zhongjing, there is still land, as long as it can be reclaimed and used for planting, it can still survive the difficulties, on the other hand, it is to increase the smelting manpower, when the army of the Liao State recovers its combat effectiveness, what has been lost in the past can be regained.

I have to say that at present, there are still some capable people in Liao, their approach seems to be a little shrunken turtle, but it is currently the most suitable for Liao, according to this, as long as the direction of Hanmin is given, it may not be a Zhongxing, hundreds of years later, the Jurchen did this, the Manchu Qing Dynasty from the very beginning, a border force, developed into a force that destroyed the Ming Dynasty, those from the Han people support is indispensable.

No longer divide, equal the Han people, or improve the status, under these talents of the Han people, whether it is farming or smelting, they can develop rapidly, even the Jurchens in the border areas can develop, not to mention the Liao State with the skeleton of a great power.

It's a pity that the Liao State was really born at the wrong time in this era, they are located in the north of the Northern Song Dynasty, which is booming in the Northern Song Dynasty, take the clouds, after digesting it, the powerful Northern Song Dynasty will continue to attack, if there is no external force, maybe a few decades later, destroy the Liao State, and unify the entire East Asia, this is not a problem.

However, what is more terrifying is that the navy, from the beginning of the northeast, announced the future of the Liao country, now, everything has no foundation, there is a 2 year, in the northeast and Mongolia after the construction of a series of cities, roads, and even railways, the attack from the northeast, will destroy the Liao country faster, this is doomed.

The Liao State is accumulating strength, the Dinghai Navy is developing rapidly, and the Northern Song Dynasty is still developing steadily, even for Han Qi, who has just become the prime minister, and Renzong, who is middle-aged and prosperous, this is the most comfortable moment.

In the eighth year of Qingli, the Northern Song Dynasty was more comfortable than the seven years of Qingli, and all kinds of factories began to appear in the sixth year of Qingli, because of the transfer of the Dinghai Navy, became more outstanding, and the entire industrial scale increased tenfold in the seven years of Qingli and the eight years of Qingli, although the tax revenue did not increase to ten times so terrible, but there were several times, plus the total net profit of the central government, it is unceremonious to say that the eighth year of Qingli is a peak.

The fiscal revenue has exceeded 120 million yuan, which is only a fraction of what it is now compared with four years ago.

The huge gains also made the Northern Song Dynasty relatively confident, and when the Dinghai Navy attacked and consolidated the Northeast, at the end of the seventh year of Qingli, after steadily attacking Youzhou, it began to attack Yunzhou.

In the face of such an attack, Yunzhou basically has no resistance, as early as when the counterattack against Youzhou failed, the Liao State has begun to shrink to a certain extent, shrinking the forces back, Yunzhou does not even have a decent city, the only big one, and was burned by Yuan Hao, and has not recovered its vitality until now.

The Northern Song Dynasty almost didn't waste much effort, and took back Yunzhou, starting from Shanhaiguan and the entire part of the Great Wall.

After taking this key defense system, because the central government of the Northern Song Dynasty had money, some people proposed to rebuild the Great Wall and improve the defense system of the entire northern Northern Song Dynasty.

This proposal has really been approved by many people, after all, from ancient times to the present, for such a long time,

The Great Wall is the defense foundation of the entire Central Plains nation, from the Spring and Autumn Period and the Warring States Period, to the Qin and Han dynasties and even the Tang Dynasty, that is, to the Song Dynasty, because the former emperor Shi Jingjiao sent the clouds out.

In order to resist the huge military superiority of the Liao State, the Northern Song Dynasty had to place a large number of troops in Hebei, not only a huge garrison, but also a large defensive pass, which occupied the land that should have become fertile land.

Now, with the recovery of Youyun, on the original unobstructed Hebei Plain, and the Youyun Mountain Range, the deployment of troops, the difficulty of defense, this is completely different,

If there was no money before, the Northern Song Dynasty was still in an economic deficit, even if it occupied Youyun, it was necessary to consider whether to build the Great Wall.

But now, because of the substantial increase in income, it will increase by 20 or 30 million almost every year, that is to say, according to this increase, in the next five years, 15 million to 20 million can be invested every year for this project.

Even if the Great Wall itself has fallen into disrepair for a long time, and most of them have been abandoned, the huge amount of money, steel, cement and bricks will make the original heavy and expensive Great Wall much easier, maybe forty or fifty million, and the entire Great Wall can be repaired once.

When the direction above the court hall was moved to the Great Wall, some people put forward different opinions.

It is the current Prime Minister Han Qi, who, together with Fu Bi and Ouyang Xiu, jointly put forward the idea of postponing the construction of the Great Wall.

The Great Wall is a barrier, but also a military fortification, not to mention remembrance and memory, simply on the Great Wall's defense system, the defense effect above, you can see that this needs to be built.

And the example given is Shanhaiguan

With 4 fortresses, the Shanhai Pass was completely blocked, so that the enemy brigade could not enter, compared to the winding Great Wall, this investment is less, and the defense is also stronger.

In this sense, the Great Wall not only costs a lot, but also has no effect, it is really repaired, it is not impossible to repair, the financial situation of the Northern Song Dynasty, can support such a huge project, and it will not cost the people and money, but the key is that it is not needed.

The army of the Northern Song Dynasty is now strong enough, which can be seen from taking down Youyun, and has mastered a terrible defensive weapon, the fortress, as long as the number of fortresses is enough, why bother to build the Great Wall.

The only problem with the fortress guards is that they cannot block the entire national border, and if the Liao State takes a detour down the mountain, it will be a problem.

But on the mountain, how much can be detoured, the high mountains in the north, as long as some mountain passes that can be crossed by large-scale cavalry, just a detour from the mountain, the horse can not be brought, without horses, with a small group of Liao infantry alone, it may have an impact on the border market, can it really threaten the Northern Song Dynasty, the same number of infantry, the Northern Song Dynasty is not afraid of anyone.

After a long period of discussion, after a series of research and judgment, the Great Wall repair was rejected, the Great Wall relics left in the past, the selection of better, suitable repairs, the combination of defense and commemoration, instead, is a large-scale construction of the fortress, Youzhou and Yunzhou defense line established, first these two pieces of land into the scope of operation, and then a meeting to consider whether to continue to the north to destroy the Liao State, or in detail, deep into the northwest, the powerful Northern Song Dynasty, has the momentum of expansion.
