If you put it on paper, you will go crazy, but when you really see it, it is the same, even if you look at it a little bit, it will take 10 days to go through the whole part, but you have seen more than 25 hubs, of which 15 are newly dug artificial reservoirs, and 10 are natural lakes.

These lakes that look so ordinary on the prairie, after some dredging and excavation, with ravines and natural river channels, and the entire northwest water system, are united into one, and on the vast land of tens of thousands of square kilometers, will open the largest and terrible farmland siege in the entire Northern Song Dynasty.

Such a huge water system, water flows, lakes and canals, together combined into a whole, is not perfect now, only about half of the completion, about 4,000 miles of sleep, but with the water source, lakes, plus rivers combined, resulting in more than 30,000 miles of effect.

It also means that a mile-long gully can reach the impact of about 1,000 acres of irrigated land, so 30,000 miles also means 32 million acres.

As soon as this number came out, everyone didn't dare to say it, it was too huge, although the entire Northern Song Dynasty had more than 80,000 acres of land, which was the entire Northern Song Dynasty, on top of the vast land, Lingzhou plus the northwest, in a year or two, it could grow so much, for the Northern Song Dynasty, the effect was huge.

Borrowing natural canals, compared with the canals actually used for irrigation, their irrigation capacity is limited, and there are even duplications in some places, but once the remaining 4,000 miles of canals are completed, the whole project will exceed the previous projections, creating fertile soil for the entire northwest.

This is the most ideal data, but not the final data, specifically Lingzhou side of the statistics, but when the entire water conservancy project is completed, about 50 million mu, can be expected.

This is a terrible and shocking number, a 600,000 mu of irrigated land, has shocked the officials from Bianliang, more than 50 million mu, representing 150 million stone of grain output, which is very terrible for the entire northwest.

Not only can grain be self-sufficient, but it can even be supplied to the entire northern part of China, which will give strong support to the relatively weak northern environment.

Agriculture-oriented, this is a thing that no feudal dynasty can ignore, no agriculture is unstable, not that agriculture is very profitable, no, agriculture has always been unprofitable, but without agriculture, everything does not exist.

If a person wants to maintain a basic life, if he has simple food, he will need 5-6 stone of food for a year, and without this food, he will not be able to survive.

For the small people of Shengdou, their requirements are not high, to live, to maintain a basic food and clothing, such a humble demand, if the people in power can not be satisfied, it will be a terrible war.

Since more than 1,000 years ago, after Chen Sheng and Wu Guang's voice, the prince and the prince Xiangning had a kind of relationship, China has formed an inherent reincarnation, no matter how strong the dynasty is, it is only a few hundred years.

The powerful Han Dynasty and the Tang Dynasty were all like this, when the peasant army revolted and rose up, in order to survive and for a bite to eat, they turned into terrible warriors and overthrew the seemingly powerful dynasty in one fell swoop.

Feudal dynasties like to revise history, in order to summarize the law in the change of dynasties, in the historical events that have occurred, then food is a key point, in the already weak environment, once it encounters a large-scale disaster, it is a disaster for a powerful dynasty.

At present, the environment of the Northern Song Dynasty, the development of land, and the increase in the amount of grain have always been a key point, and no one thought that the barren northwest would suddenly release such a big surprise, and when the number of acres of land increased reached 10 million, this was already of decisive significance.

If you discount the possible grain produced in the northwest, 10 stone a year, 150 million stone of grain can support the daily consumption of 15 million people, which is still a huge waste of the premise.

In this era, the Northern Song Dynasty has more than one-third of the world's population, there is no systematic statistics in this era, in 1640, it was about 540 million people, during the Northern Song Dynasty, there were more empires, and it was relatively stable, but it would not exceed this, about three or four hundred million.

However, the vast majority of this population is not distributed in the Central Plains, to be exact, along the banks of five rivers linked by the Beijing-Hangzhou Grand Canal.

It was the real essence of the Northern Song Dynasty, not only Sijing, Jiangnan and other places, all of which were among them, but also the most fertile, the most developed places in transportation, in those places, even a small county, as little as 50,000 or 60,000, as much as 100,000.

But that is in the most elite area of the Central Plains, in the northwest, it is really considered to be poor.

The population abounds in counties with thousands of people, and even appears, hundreds of counties, this is not also a county seat, this is a complete county, more than 100 li, and even in the county seat, there are less than 1,000 people, because of this, the population of the northwest is very small.

At present, the entire Northwest Fourth Road, plus the newly attached Lingzhou, has a population of just over 1 million on the huge land, that is to say, even if we consider that the northwest will attract a large number of people in the future, reaching 5 million people, and at least 100 million stones, which can be supplied to the outside world, this is the food that can be supplied openly.

The road to the border is difficult to walk, if Lingzhou here, there is really such a grain supply capacity, at least speaking, in Jingzhaofu, the northwest, grain can be solved, than from the south of the Yangtze River, and then not far away, from Bianliang to the northwest, I don't know how much to save.

Not to mention the areas close to the northwest, for example, Shaanxi, and a little south of Guanzhong, close to the mountains of Sichuan.

From the northwest, it is still a little closer, and even because of the presence of a large number of cattle and horses, it is possible to transport a large amount of grain.

Those who have a little experience in local governance will know how much benefit a place that can produce hundreds of millions of grains when it is developed.

Especially from the Privy Council, he knew better that food was important to the border.

In the Privy Council, there is a special department for preparing all kinds of materials at the border, and this department is the largest in the entire Privy Council, and it is also the hardest ever.

They need to mobilize materials from all over the country, and then transport them to the border through various methods, and the largest amount of grain is grain.

The reason why the northwest is unstable and bullied by a small Western Xia is because of its own weak foundation, and the local grain cannot even be attacked by one-tenth of it, and all of it needs to be transported.

The road from Bianliang to the northwest is relatively difficult to walk, all kinds of mountain passes, the most important thing is that there is no huge city, all the things needed to replenish need to be brought, a trip down, simple transportation, it will cost two or three times the consumption, which is also the root of the long-term high grain.

Often, 3 stones of grain are sent to the border pass, and in the end, if it really falls into the hands of the border pass, 1 stone is considered good.

What is Western Xia, even in the most serious time, the Northern Song Dynasty did not regard him as a big problem, at most it is just to affect the northwest, if the location of Western Xia is changed to Hebei, with the weak strength of Western Xia, Hebei can easily mobilize hundreds of thousands of elite forbidden troops, with the support of enough food, grass and vehicles, forcibly attack Western Xia.

Historically, the Western Xia was almost destroyed by the Northern Song Dynasty, and that's it, when enough funds were concentrated to fight with the Western Xia, through Tubo as a springboard, under the command of an excellent general, and then through the method of war, the final victory was obtained.

If the Western Xia had not been blown up by Han Qi before, the walls of Xingqing Mansion would have been blown up by Han Qi, and in the end, all the soldiers and civilians, in the face of the absolute power army, would have burned all the jade, relying solely on the foundation of the current development of Lingzhou, at most 3 years, Lingzhou would have been able to accumulate enough strength to attack the hinterland of Western Xia.

Now, these are a thing of the past, peace has become the key to the development of Lingzhou, and this huge water conservancy project has become the most important project at present.

10 days is enough for these officials to understand that Lingzhou is such a huge project, and there are broad prospects, with the help of this method, after shocking these officials, Han Qi also really said his purpose, requesting, the center to solve the problem of immigration, and all of a sudden, it is a lion who opened his mouth, within a year, to guarantee 2 million, and in the next 5 years, it will reach 5 million one after another.

Han Qi's loud words made all the officials a little dizzy, 2 million, 5 million, there are only a few people in the entire Northern Song Dynasty, almost a dozen, and Han Qi is so justified in what he said.

However, Han Qi didn't say much on this point, only mentioning that if there is not enough population, the development of the entire northwest will be in a state of stagnation, and even wasted.

50 million acres of land, the land that can be developed in the future may reach 70 million, plus a large number of livestock, cities, commerce, these together, do need so many people, this point, Han Qi is right, but sometimes, it is not possible to feed so many people, but can get so many people.

For these officials who are no more than 5 ranks, let alone millions of immigrants, even if they are tens or hundreds of immigrants, they are not able to decide.

Large-scale immigration, for the feudal dynasty, is a very cautious thing, for the era of imperfect logistics support, prone to all kinds of problems, a bad one, then it is not to send tens of thousands of people to immigration, that is to directly send so tens of thousands of people to the ghost gate.

Of course Han Qi knew this, and he didn't expect that these people would be able to help him decide, he just asked these people to write down what they saw and heard, and send it to Bianliang through an eight-hundred-mile expedited or something, and he believed that the princes of the court could help him solve this problem.
