Let the Ordnance Department build agricultural tools, it is a very extravagant behavior, and the efficiency is not high, using the iron used by the military, it may not be very bad, but it will be relatively wasteful, because these are not focused on agricultural tools, let alone what surface carbon and combined steel technology.

Sometimes, it is not that steel is not as good as iron, under the premise of the same funds, the appropriate use will not only reduce the cost, but also greatly improve the effect.

The iron output of the Daimyo's Mansion is already quite terrifying, not to mention two or three hundred thousand tools of all kinds, even if it is several million or tens of millions, it is only a period of time before it can be produced.

However, the distance required from the Daimyo Mansion to Lingzhou is relatively long, even if it is expedited with 800 miles, it will take a certain amount of time.

Han Qi sent a total of two letters, both of which were sent before coming to Weizhou, one letter was to the Daimyo's Mansion, in his own name, to order a batch of tools, which would be used in the development plan of the entire Lingzhou, and the other was handed over to Zhao Xin.

It's not that Han Qi wants to belong to Zhao Xin's camp, but the two contacts between Baozhou and the Daimyo Mansion made him feel that Zhao Xin is a very capable person, and sometimes, he can always think of a way to do things that seem impossible.

Lingzhou's move is very big, and he is not sure that he will get enough funds, but he also wants to hear Zhao Xin's thoughts.

Although it is said that in this era, the distance is to cut everything off, from Lingzhou to Dingjun, the distance of more than 3,000 miles, even if it is 800 miles expedited, it will take four or five days to arrive, but it is enough to deliver a letter.

Zhao Xin had already left Dingjun at that time, and he received this letter in Suqian, and after receiving it, he was very surprised.

He really didn't expect that Han Qi would start such a terrible project after the victory, which was a good thing.

The Yellow River has always been a hidden danger in the whole of northern China, because of the floods caused by the Yellow River, I don't know how many, you know, Bianliang is next to the Yellow River, once the Yellow River floods on a large scale, the final impact will be unimaginable.

Zhao Xin, who is familiar with the history of the Northern Song Dynasty, is very clear that the Yellow River will usher in a diversion in the eighth year of Qingli, in the historical records, the large-scale diversion of the Yellow River, a total of 26 times, among them, in the middle of the Northern Song Dynasty, from Renzong to Shenzong, less than 60 years, there are two, it can be said unceremoniously that the Yellow River was diverted, which opened a huge financial problem in the Northern Song Dynasty.

In Zhao Xin's plan, the construction of the Dinghai Navy reached a certain level, and when the Dinghai Navy had enough funds, he would almost inevitably start the transformation of the Yellow River.

This will be an unprecedented renovation that will include tree and grass planting, soil and water conservation in the middle and upper reaches of the Yellow River, the reinforcement of dikes and dams in the middle and lower reaches of the Yellow River, the enhancement of water conservancy facilities, and a series of water conservancy projects on farmland.

Unexpectedly, when he had not yet started this project, Ye Qingchen of the Central Plains and Han Qi of the Northwest both started this project, although this is not a systematic governance of the Yellow River, but it is beneficial to the Northern Song Dynasty and the Yellow River.

Even Han Qi and Ye Qingchen can see that the construction of these water conservancy facilities is beneficial to the Yellow River and the land, and Zhao Xin can certainly see that Ye Qingchen did not ask him for guidance, nor did he ask him for guidance, as a Dinghai Hou, it is not good to get involved rashly.

However, Han Qi clearly wanted to ask his opinion, so there was an opportunity, compared with the hub of the Central Plains that focused on water conservancy facilities and increased water volume, the changes in the Hetao Plain in the central part of the country made Zhao Xin value it more.

In itself, the changes of the Yellow River are produced from the Loess Plateau, once the Loess Plateau, the soil and water conservation increases, and if the soil is locked, the benefits to the entire Yellow River are huge, for this reason, he does not hesitate to give full support.

Materials, funds, and all kinds of tools, as long as they can have an effect on the whole project, were opened, and at the same time, the navy was instructed to mobilize a group of engineering personnel to go over.

Funds, tools, these things are very important, but in Zhao Xin's view, the number of engineering personnel is not much, only about 500 people, but the technology is mastered, and a large number of tools are carried at the same time.

This tool is not an ordinary shovel, shovel or the like, simple and ordinary tools, they include some portable hoist cranes, small-scale tensile devices, and some animal power tools, these tools can greatly improve the efficiency of construction, these are not the technologies that the Northern Song Dynasty has.

In the current Northern Song Dynasty, in terms of architecture, if you want to find a first, that is, the Dinghai Navy.

Zhao Xin brought more advanced management, but also brought a large number of tools, in just a few months, Dingjun has completed nearly 3.5 million square meters of housing construction, at least more than 300 kilometers of roads, and 37 kilometers of railway loops, the role of the middleman is there, but more tools.

In the large-scale repetitive work, large-scale water conservancy construction, the three major engineering theories of later generations are very important, as long as the simple use, can greatly improve the efficiency, and what does the efficiency represent, on behalf of the faster, more economical construction of these large-scale projects.

Efficiency is a theory that has not yet been studied in this era, and it has not even been involved in it, but for the efficiency of large-scale projects, it has actually increased.

Completely in accordance with the traditional experience, regardless of the overall efficiency, the improvement is very limited, after reaching a certain limit, can only be a little bit, a little bit of improvement, such a small improvement is very small.

However, efficiency is equivalent to carrying out from another level, using an overall approach to reduce some unnecessary waste of time, reduce some complex and repetitive work, and finally greatly improve efficiency in a limited time.

In Dinghai, through the assembly line, it can even increase the production efficiency by a thousand times, and now the average production capacity of the group can be equivalent to the efficiency of thousands of blacksmiths, which is the fundamental reason for the high quality and low price of Dinghai.

In the construction of large-scale projects, it may not be possible to achieve that kind of efficiency, and it is quite certain to improve by three or four percent.

These technicians of the Dinghai Navy are far more transcendent than the entire era, and in the huge construction of the Dinghai Navy, they have been gradually completed, although they do not have a systematic theory, but they are simple, and they will still be able to.

Don't underestimate these simple ones, this is a theory that countless experts have spent decades, or even hundreds of years, in many details, in many investigations, and finally summed up, which are the shining points of human wisdom.

Some things, for example, machine guns, tanks, battleships, fighter planes, these, far exceed the technological level of this era, unless it can be embodied with a card system, otherwise there is no way to achieve it in this era, basic technology, that is not a simple breakthrough, or an accident, can be long ago.

However, there are some things that are not limited by this era, such as the three major system projects, although this is the most high-end of the system engineering, and it is also the most in-depth science and technology studied in later generations, but in fact, it is not so difficult.

The basics of co-ordination are actually very simple, it takes 10 minutes to boil a pot, 5 minutes to buy groceries, and 3 minutes to fold clothes. If you do it in order, it will take at least 18 minutes, but if you add the latter two to the boiling time, it will take only 10 minutes at most, and you can complete all three tasks.

The overall planning of real industrialization, or even parallel engineering, requires systematic research, and even many experiments and adjustments, but as long as there is this theory, and then try according to this theory, really, it does not need too much, and it can be achieved in the Northern Song Dynasty.

In the Daimyo's Mansion, in the Dinghai Navy, parallel engineering and co-ordination have begun to show their effects, Zhao Xin is more in smoothing these things, and now, these engineers who have a certain amount of experience and have initially mastered some simple methods, with the unique tools of the Dinghai Navy, when they leave the Dinghai Navy and go to Lingzhou, this system will take root in Lingzhou, and in the next project, burst out with brilliance.

It turns out that the development of Lingzhou is smoother than that of the north, and there are such and such constraints in the north, and sometimes, there will even be a long ditch wasted in vain for a completely meaningless place.

But Lingzhou is different, all of them are borderless land, Han Qi can enjoy calligraphy and painting on it, some low-lying land, reasonable geographical location choice, at least can save more than 4% of the earthwork, and at the same time, the dense water network and various lakes and tidal flats will make the overall effect better.

In fact, the most outstanding thing is the huge manpower, the population in the north is more, but what Ye Qingchen can mobilize is only a small part of this, and more can only be through the method of labor.

The taxes in the Northern Song Dynasty were not heavy, but the reason why the pressure at the bottom was huge was that in fact, it still depended on all kinds of labor, and some terrible labors could even bankrupt the first and second class households.

Ye Qingchen is a Qing official, of course, it is impossible to requisition without scruples, in this case, at most, the construction personnel at the same time are about 200,000, and there is not enough animal power as a supplement, and even sometimes, if the agricultural time is delayed or for other reasons, it is necessary to stop work.

All of this, in Lingzhou, does not exist, completely ownerless land, free calligraphy and painting, good environment, has made this farmland and water conservancy twice the result with half the effort, and now, with the support of the Dinghai Navy, what else can restrain this.

Han Qi is very satisfied with the progress of this construction site, in fact, under the premise of sufficient funds, he has to fully roll out the effect, according to this speed, at most 60 days, the main project can be completed, and the water injection will begin.
