In later generations, the pumps were made of steel, and the smaller ones were made of plastic, and these two materials, one could not be made, and the other was too difficult to manufacture and too costly. Pen ~ fun ~ pavilion www.biquge.info

The plastic pipe was made by Ang Lee without the ability, and he did not have the equipment to make plastic pipes, and the long iron pipe with a length of more than three or five zhang was a headache for Ang Lee to think about, let alone manufacture it.

Therefore, think about it, no matter from which point of view, with the middle of the thick bamboo pole, is always the best choice, as for the bamboo pole is easy to damage, it is too simple, change a good one, and, after a variety of processes to deal with the stout bamboo pole, it is not so easy to damage, use for three or five years, there should be no problem.

The news of the successful research and development of the pumping machine was soon presented to Li Longji, who learned that Li An had once again obtained a scientific research success, and that it was an extremely important achievement for spring ploughing.

After Li An got the will, he immediately opened up a production line for the core components of the pumping machine in the R&D center, and the pumping and drainage pipes were drawn on the drawings for people to take to Jiangnan, and find the largest diameter of bamboo in Jiangnan, which was processed and made on the spot, and then put the finished product into a wooden boat and transported from the Grand Canal to Luoyang City, and then, from Luoyang City, it was loaded onto a train, transported to Chang'an City, and finally assembled into a qualified pumping machine.

And in order not to lose time, the steamship will be put into use, and the wooden boat loaded with bamboo poles will be towed, and quickly go to Luoyang City.

Like the ploughing machinery, the pumping machinery also has a unique advantage, for this reason, many nobles after seeing the ability of the pumping machinery, but also played the intention of ordering.

Of course, the pumping machinery is different from the cultivation machinery, can not be sold to the nobles, the court also has to keep a part, otherwise, there will be a noble field will never lack water, but the fields of ordinary people are difficult to get water sources, the court mastered a large number of pumping machines, in order to draw water on a large scale, so that the fields of the people on high ground can also be watered in time, so as to ensure the output.

Ploughing machinery and pumping machinery have been successfully developed and entered the stage of mass production, which makes Li An very excited, and next, Li An can continue to develop new machinery.

In order to speed up the speed and quality of manufacturing machinery, Ang Lee aimed at processing machine tools, and with the power of the steam engine, it was completely possible to produce power machine tools.

At this moment, many of the products processed by Li An are hand-cranked machinery, for example, the polishing of the inner surface of the solar cooker is hand-cranked polishing machinery, which is very tiring and the efficiency is not very good.

If the power of the steam engine is installed on the hand-cranked polishing machine, the efficiency of polishing will be greatly increased, and the polishing effect will be much stronger, which is inevitable.

In addition to the polishing machinery for the manufacture of solar cookers, other hand-cranked machinery for manufacturing parts can also be equipped with the power of steam engines, thus greatly improving efficiency.

With this idea in mind, Ang Lee immediately dispatched a large number of outstanding talents to research and develop these machines, and the manufacturing work was handed over to craftsmen with less skilled skills.

In fact, after more than half a year of development, there are more and more technical talents and coolies near the R&D center, and now, the total number of people has exceeded 30,000, and the daily consumption of food alone is very considerable.

Fortunately, the value they have created far exceeds these consumptions, otherwise, even the financial resources of the treasury will be dragged down by these people, which is why Ang Lee is always so black-hearted, and will sell products at two or three times the price, in order not to increase the revenue of the treasury, so as to relieve the pressure of continuing to develop black technology in the future?

Because Ang Lee has been developing a variety of hand-cranked machinery, and the technology of the steam engine is relatively mature, it is really not difficult to install various hand-cranked machinery on the steam engine, for this reason, breakthroughs were made one after another, and a large number of steam-powered machine tools were manufactured and put into production, so that the production speed of various products was greatly increased, of course, it also made Ang Lee very happy.

Harvesters and dredging machinery are all said by Ang Lee to be developed, but these are not urgent, Ang Lee is not in a hurry to develop these two things, after all, Ang Lee also has to develop and manufacture various steam machine tools, even if there are 30,000 manpower as the base, Ang Lee is still a little powerless, and he can't spare the energy to develop harvesters and dredgers for the time being.

Winter is coming soon, and heavy snow hits without warning, which makes the whole Guanzhong enter the snow-white fairy tale world, and also makes Ang Lee's mood feel very comfortable, this snow-white world is Ang Lee's favorite.

Of course, it was not only Li An who was in a good mood, Li Longji's interest was also very high-pitched, and he made the decision to visit Luoyang City.

However, this time, he only planned to stay in Luoyang City for three days and return after three days, and the purpose of going to Luoyang City was mainly to enjoy the intoxicating scenery along the way, and of course, the snow scene of Luoyang City.

As a core courtier, Li An must of course accompany him, and in order to ensure the safety of the emperor's travel, the railway operation from Chang'an to Luoyang was once again briefly stopped.

Only this time, at Li Longji's request, everything is simple, there is no need to carry too many things, and the personnel must be streamlined to ensure the speed of travel.

When the royal train started, Li An was lying in a private room in the sixth carriage, looking at the beautiful snow scene outside the window, and his mood was good!

At this moment, the temperature outside the train is below freezing, and the soft sleeper car where Li An is sitting is equipped with an ultra-thin fireplace, and the temperature is still relatively warm, although it is not as good as the air conditioning fee in later generations, but at least it will not feel cold, and there is a quilt in the box.

"Da Lang, are you looking at the scenery?"

Li Shizhi didn't knock on the door, and walked in.

"Liuweng, please sit down and see, how beautiful the snow scene is outside!"

Li An didn't treat Li Shizhi as an outsider, and didn't get up, and directly let Li Shizhi lie next to him and accompany him.

"Haha! Being able to lie in the warm carriage and calmly look at the scenery outside the window is all thanks to you! ”

Li Shizhidu was used to it, smiled, lay on the soft couch next to Li An, and calmly looked at the snow scene outside.

In the past half a year, due to the reuse of Emperor Li Longji, he has been idle a lot, and he is about to become a corpse vegetarian person, but fortunately, Li Linfu will always find something innocuous for him to do, so that he feels that he still has a little use in the court, and he will not be a waste.

"It doesn't matter if you don't take credit or not, but it's enough to be able to lie in the train and watch the beautiful snow outside the window.

Li An opened his mouth to comfort Li Shizhi.

Li Shizhi looked at Li An suspiciously: "Da Lang, you are now a celebrity next to Your Majesty, and your status in Your Majesty's heart is only afraid that it is not lower than that of the right minister, it is when the spring breeze is proud, how can you have such feelings?" ”

Of course, Li Shizhi will not know that Li Ang is a human being in two lives and has seen more things, so he will have this kind of open-minded feelings.

"Liu'aweng, let's look at the snow, it's a pity not to appreciate such a scene."

Li An smiled at the corner of his mouth and began to change the subject.

Li Shizhi didn't delve into it, smiled, and said: "The scenery outside the window is indeed very beautiful, these are the beautiful rivers and mountains of my Tang Dynasty, after the railway to Anxi is built in the future, I must see the yellow sand there with my own eyes." ”

"Liu'a Weng rest assured, in two or three years at most, the railway to Anxi will be through, and with the strong national strength of my Datang, it can be completely done."

Li An said confidently that after the spring ploughing in the coming year, the two railways leading to Yumen Pass and Zhongshou City will begin to be laid, and with Li Longji's personality of great joy, it will inevitably be a large-scale requisition of the people along the way, in addition, it is necessary to levy labor in Guanzhong and Luoyang, with strong manpower as the backing, the laying of the railway will inevitably be completed quickly, even faster than the laying of railways in later generations, which is the result of the manpower invested.

In order to dig the Grand Canal, the Sui Dynasty used millions of manpower and poured the country's wealth, and even if the later generations carried out such a large project as the Grand Canal, they would never use so much manpower, at most tens of thousands of people, and then, use advanced machinery for construction, so that the progress may not be faster than in ancient times.

After all, all kinds of large projects in later generations, the manpower invested is relatively small, machinery can increase the efficiency of a hundred times, but the manpower is reduced by a hundred times, so, the speed is about the same, and the loss of national strength, the proportion of large projects in later generations is too small, and in ancient times, large projects are often the strength of the country.

"Da Lang, cultivators and pumps have begun to be built in batches, and I heard that harvesters will also be developed soon, so I don't need so many people to farm in Datang, how to settle these people, have you thought about it?"

Li Shizhi asked worriedly.

"Liuweng, I'm short of people now! There are 30,000 craftsmen in the R&D center, but it is far from enough, and there is a need to temporarily recruit a large number of people every time to lay the railway, if the people do not need so many people to farm, in the future, you can set up a special railway craftsman, in this way, not only can you lay the railway when the farm is slack, you can lay it at any time, in addition, I have a lot of practical things to invent, these require a lot of manpower, so, the less the population of farming, the more beneficial it is to the Tang Empire, if one person farms, you can feed ten people, Isn't that a great thing? ”

Ang Lee opened his mouth to explain.

He knew that Li Shizhi's thinking was still in an agrarian society, and he did not quite recognize the industrialization of the empire, but the trend of the times could not be changed, and the smaller the agricultural population, the stronger an empire would be.

"Oh, what you said is also true, one person farms the land to feed ten people, so that the Tang Empire will never suffer from famine again, a good thing, this is a good thing!"

Li Shizhi thought about it according to Li An's train of thought, and felt that it was indeed a good thing, but soon asked: "Once a large number of people lose their errands for farming, how to ensure that they will be able to find something to do, if more than half of the people really don't need to farm, can you really accept everyone if you build machines and build railways?" If there are still many people who cannot find a way to make a living, will there be chaos in the world? ”

Li Shizhi's concern does have some truth, but he also overestimates the ability of these machines to cultivate the machine, according to the current production capacity, these machinery can only alleviate the demand of the Tang Empire for the agricultural population, so that a small number of people lose their agricultural jobs, so as to transfer to industry, and the industrial scale of the Tang Dynasty will gradually expand and improve.

In order to achieve a virtuous circle of a decrease in the agricultural population and a corresponding increase in industrial demand, it will naturally not lead to a large number of idle people in Datang.

The appearance of a small idle population is not a big deal, as long as it is properly controlled and social security is perfect, chaos can be completely avoided.

Li An said his countermeasures one by one, and assured Li Shizhi that the decrease in the agricultural population and the increase in the industrial population will definitely form a virtuous circle, and there will definitely be no chaos in Datang.

Li Shizhi understood half of it, he still didn't understand the issue of social security, which was tantamount to letting some people who had no ability to make a living eat and drink for nothing, and what they lost was the wealth of the imperial court, and it was not in the time of famine, such normalized disaster relief was easy to breed lazy people.

After Ang Lee carefully explained the many benefits of social security, Li Shizhi fully understood and agreed with Ang Lee's point of view.

The scenery outside the window is constantly changing, although it is always snow-white, but the shape is different, there are white trees, white flat land, and white tall peaks.

After talking with Li Shizhi about the relevant knowledge of industrialization, Ang Lee has been quietly enjoying the snow-white scenery outside the window, and he is in a comfortable mood.

Li Longji in the third carriage was also very comfortable, lying on the wide soft bed, hugging the delicate Yang Yuhuan, and enjoying the fairytale scenery outside the window with him.

Different from the carriage where Li Ang is located, the carriages where Li Longji is located have more ultra-thin fireplaces installed, and the insulation measures are also relatively good.

For this reason, although it was snowy outside and the temperature was below freezing, the carriage where Li Longji was located was as warm as spring, and in a later sentence, it was called the best comfortable temperature for the human body.

In such a warm carriage, Li Longji did not need to wear cotton clothes, only clothes with autumn thickness, and Yang Yuhuan was fatter and wore less, no different from summer clothes.
