Li An got up and slouched and slowly walked out of the car, just now Li Yu and Li Li had been enjoying the changes in the scenery outside the car window, but he was lying on the rocking chair, resting for a long time with his eyes closed. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Of course, Li An knew that Li Yu and Li Li were already a little impatient, and now that noon was approaching, and the sunlight was strong enough, it was the time for the magnifying glass to show its might.

"Let's go, let's go play something good."

Li An jumped out of the carriage, walked to the processing factory, and immediately asked the craftsman to bring the processed magnifying glass.

"Li Shilang, what is this? How to play? ”

Li Yu and Li Li both saw the magnifying glass for the first time, although they knew that it was made by Yaoyu, but they didn't know how to use it, and for people who came into contact with the magnifying glass for the first time, they should not know the use of the magnifying glass.

"This is called a magnifying glass, it can magnify objects many times, and it can also be used to gather light, and the eyepiece of the telescope uses this thing, but that one is too small, and this one is bigger and more fun."

Ang Lee explained in a whisper, then picked up the binoculars and walked to a place infested with ants.

"A magnifying glass can concentrate energy on a single point, and this point will be very hot, and it can kill ants in an instant, you see."

Li Ang focused on the white bright light and aimed at the slowly crawling ant, and in a split second, the ant was burned and struggled, and soon curled up into a ball and died in pain.

"The ants were really burned, it's really a good thing, Li Shilang, let's try it too."

Li Yu and Li Li, each with a magnifying glass, began to carry out a brutal massacre of the ant army, all the ants seen by the two of them, almost none of them were spared, and all died miserably.

"Well, this thing is fun!"

Ang Lee asked proudly.

"Cool, it's so cool."

Li Yu didn't learn much else, but the word Shuang learned quickly.

"Okay, the ants have been slaughtered by you, and you will use a magnifying glass to prevent the ants from going on and see if the ants have become bigger."

"Li Shilang, the ants have really gotten a lot bigger! Even the calves can be seen clearly, it's so fun, no wonder it's called a magnifying glass. ”

Li Li replied excitedly.

"What more can a magnifying glass do? There is no pressure to use it to light the fire, Wang Ba, go find some paper. ”

Since Li An was going to give the magnifying glass to Li Yu and Li Li, he naturally wanted to let them understand the various functions of the magnifying glass.

Soon, some useless paper was sent over and handed over to Ang Lee.

"You see, a magnifying glass can ignite the paper in a very short time, but of course, if the sunlight is not strong, or if the paper is wet, then it can't be ignited."

Li An said, using the magnifying glass in his hand to ignite the paper.

"It can still be used as a fire fold, Xiao Wang will also try it."

Li Yu was very interested in this, and Li Li also picked up a piece of paper to test, and the results of the experiment were very successful, and the paper was ignited.

"King Guangping, Shiro, you have to remember one thing, when there is sunlight, the magnifying glass will gather heat in one place, so it can ignite paper, it can also burn ants, and it can also burn grass and leaves, but you must not put your hands on the light spots, otherwise you will be injured."

Li An reminded seriously, he was very worried that these two and a half children would hurt themselves out of curiosity, if that really happened, he would be to blame, after all, the magnifying glass was given to them by himself.

"Li Shilang is too worried, we are not children, my children are one year old."

Li Yu pretended to be a father, but this still couldn't hide his immaturity and immaturity.

Although having a woman is a sign of a man's maturity, but in ancient times, men and women got married too early, so even if many people became married, they still had the childishness and naughtiness of children.

"King Guangping, Shiro, the spring ploughing is coming to an end, the imperial court has officially begun to lay the railway, of course, there is also the R&D center I designed, in the next few days, I may be busy, you don't have to come every day, I may not appear anywhere, but as long as I invent good things, I will give you as a gift."

Li An said arrogantly.

"Li Shilang, laying railroad tracks and building a research and development center are both major events of the imperial court, Your Majesty will definitely let us go over to see the world, we will still meet often in the future, in addition, we will come here every day, even if Li Shilang does not come, we will also come."

"Why?"

"Because there's fresh cucumbers! If you don't eat one or two every morning, you always feel like something is missing. ”

“……”

Li An looked helpless.

After Li Yuhao Li left, Li An once again drilled into the test room, he needs to develop too many projects, and many projects will encounter a lot of unknown problems, and these, all need Li An, the chief designer, to give advice and guidance to help the craftsmen of research and development to tide over the difficulties.

The magnifying glasses that Li Ang gave to Li Yu and Li Li are just gadgets with very low technology content, and microscopes with even more scientific and technological content are under development.

The magnification of the microscope is far more important than that of an ordinary magnifying glass, which is more important for the study of the microscopic world, so it must be successfully developed, and Ang Lee is full of confidence in this.

A few days later, the work of spring ploughing gradually ended, the imperial court was able to draw out a lot of manpower, carry out a variety of projects, mining mines need labor, the construction of research and development centers need labor, laying railroad tracks requires a lot of labor, these three aspects of work can not be stopped, must go hand in hand to start work, however, fortunately, in Guanzhong Longyou area people Ding Xing, can be levied a lot of labor, but do not have to worry about the shortage of labor.

Under the instruction of Li Longji, government officials at all levels in Datang began to mobilize a large number of manpower and material resources in their respective jurisdictions to prepare for large-scale projects that benefit the country and the people.

The work of mining iron ore has been on the right track, naturally there is no need to bother too much, the construction of the R&D center and the laying of railroad tracks, have detailed drawings and technical parameters, and it is not difficult, but as the chief designer, Li An must run at both ends, and solve the problems and problems encountered in the construction process in a timely manner, so as to ensure that these two major projects can be completed with quality and quantity.

With the continuous progress of the project, more and more people have arrived, more than 10,000 people have gathered near the R&D center, and on the road to lay the rails, 50,000 or 60,000 horses have been stationed one after another, not including the woodcutters who are logging in the distance, with a total of more than 100,000 people, which is appropriate.

With so many manpower and material resources, as well as the abundant financial resources of the imperial court, the progress of the project was very smooth, and there were almost no major problems.

The officials of the Ministry of Industry, who are responsible for repairing roads and bridges all the year round, have the ability to coordinate and organize, and they are still very powerful, how to work, how to deploy, how to arrange camping and eating, as well as toilets and diseases, etc., must be solved, and the officials of the Ministry of Industry can handle them in an orderly manner, which has to make Li An admire.

Of course, this is also because these toiling masses can endure hardships, and they can accept the poor camping and eating conditions, and, under normal circumstances, they are not easy to get sick, and if they are sick, they can recover by eating some herbs, and their vitality can be described as extremely tenacious.

The great project of benefiting the country and the people is extremely important for a country, so even if the people suffer, they must be done, and the benevolence of women cannot strengthen the country.

"Li Shilang, according to the current progress, in more than a month, the railroad track leading to the Hot Spring Palace can be laid, and moreover, there are still two tracks back and forth."

The official of the Ministry of Works, who is responsible for coordinating labor, has an extremely excited expression, once the railroad track is successfully completed, his credit will naturally not be small, and the chance of getting a promotion is still very large, and there is no such thing as a railway track before the Tang Dynasty, if in the future, the railway track is popular in Datang, he will definitely be recorded in history as the first official responsible for building the railroad track, and thus go down in history.

The laying of two rails is for the convenience of transportation, greatly increasing the transportation volume of the rails, and avoiding collisions caused by moving in the opposite direction.

"This is just the beginning, in the future, I Datang will lay more rails, you should take advantage of this large-scale laying of rails, summarize the experience of laying rails, and accumulate technology for the next larger-scale laying of rails."

Li An said calmly.

As the chief designer of the railway, he certainly has a higher angle of looking at the problem, and if Datang wants to dominate the world, transportation is very important, and without a railway extending in all directions, there is no ability to deter barbarians by force.

"Li Shilang reminded that the lower officials should remember the teachings and must do their best to accumulate technology and prepare for the next railway in Datang."

The Ministry of Industry officials responded respectfully.

"Okay, keep working hard, and the official will go to the R&D center to inspect."

After educating the officials of the Ministry of Industry, he took the escort team and rushed to the R&D center, which was the place where the miracle of the Tang Empire was born in the future, and it was the top priority of Datang.

The R&D center has 5,000 acres of land, which is a very large area, and more than 10,000 laborers work here, including the construction of courtyard walls and the construction of various facilities inside.

As soon as Ang Lee arrived at the construction site of the R&D center, the officials of the Ministry of Works, who were in charge of construction and coordination, came over with him.

"Li Shilang, the courtyard wall of the R&D center can be completed in one month, and the internal projects can be completed in two months at most."

Li An nodded and praised: "Good job, the construction site is in good order, everyone is working, you must carry forward the spirit of building a black powder workshop, and complete the construction of the R&D center with faster and more efficient speed, quality and quantity." ”

"Li Shilang rest assured, Xia Guan eats and lives on the construction site, and he will do his best to build the R&D center."

The official of the Ministry of Industry respectfully saluted Li An.

"You continue to command everyone to work, don't worry about me, the officer himself will look around."

Ang Lee waved his hand, telling the Ministry of Works officials to focus on the project instead of spending time on themselves as a leader.

Standing on a high ground and looking down, the labor force of the entire construction site is in full swing, and the officials are responsible for commanding, this lively construction picture is Ang Lee's favorite scene to see, especially standing on a high place and looking down.

It's like playing a game, watching your base develop step by step, and the sense of accomplishment in your heart can be imagined.

Most of the area of this base is blank for the time being, and those facilities that have begun to be built are products that Ang Lee urgently needs to develop at present.

On the far left is the workshop where the steam engine was developed, and next to it is the house where the microscope was developed, as evidenced by the towering blast furnace.

Further afield is the research department of ultra-high power telescopes, which is mainly responsible for the development of telescopes with 100 to 200 magnifications, and of course, is also responsible for improving the telescopes that have been developed, such as in terms of drop resistance and waterproofing, so that the telescope can be used in a more harsh environment.

Farther away, there are steam locomotives and steam ships ready for pre-research, these two equipment will completely change the transportation situation of the Tang Empire, which can be called the top priority of research and development, and it is also the important weapon of the future Tang Empire.

Of course, there are also some practical and easy-to-develop projects, which are arranged in a relatively outward position.

In addition, the R&D center is not only responsible for R&D, but also responsible for the manufacturing and mass production of important equipment, especially for projects with high confidentiality requirements, which must be produced in the R&D center, fortunately, the area here is sufficient to undertake productive tasks.

The R&D center and the laying of the railroad tracks will be completed within two months, and Ang Lee must produce a carriage with excellent comfort, and it is a group of several connected carriages for Li Longji's use.

Fortunately, the previous technical reserves are sufficient, produce a few individual carriages, and then make a simple connection, you can create a group of carriages, and these individual carriages, all of which are different, have different functions, and the materials are selected to be the best, after all, it is the carriage that the emperor wants to use, of course, it should be luxurious, and the facilities should be as many as possible to meet all the needs of the emperor.

Li An first designed three carriages to be connected, but after thinking about it, he felt that it was too few, not grand enough, and the functions were not complete enough, so he changed to a five-carriage design.

These five carriages include the private carriage where the emperor sleeps, the carriage for the emperor's activities and meals, the carriage for the palace maids and eunuchs, the carriage for the guards, and the last dining carriage.

In order to successfully pull these five carriages, Ang Lee had to improve the front of the locomotive and add several sets of driving wheels to share the weight of the five carriages. (To be continued.) )
