After Li Yu looked at the design drawings drawn by Li An, the whole person suddenly felt bad, his expression was quite complicated, in his eyes, there was a look of joy, there was also an embarrassed look, and even a little dissatisfied and helpless.

He sighed slightly, looked at Li An and said, "I knew that Li Shilang painted so well, so I wouldn't have painted it, wasting most of the night's time in vain." ”

Cover your mouth to control yourself as much as possible without yawning.

Hearing Li Yu say this, Li An couldn't help but laugh, as the dignified eldest grandson of the emperor, Li Yu spent most of the night actually painting a graffiti, which is really damaging to his reputation, if this picture is passed on, I am afraid that Li Yu's prestige will be greatly reduced.

"Haha! How can it be said that it is a waste of time? At least, in the process of drawing, King Guangping should have thought deeply about the problem of underground parking garages, didn't he? ”

Ang Lee said with a smile.

Finally got some recognition from Li An, a smile appeared on the corner of Li Yu's mouth, in this way, he did not waste this night, and what Li An said is also true, after thinking all night, he has indeed gained a lot, there are many questions that he has not thought about before, after last night's drawing, he thought of it, and even read some books for this purpose, to understand the demographic changes in Chang'an City in the Tang Dynasty in the past ten years, as well as the changes in consumer groups and so on.

For the necessity of building underground parking garages, there is also a deeper and deeper understanding, but due to the lack of professional knowledge, let the design of specific underground parking garages have no clue, so, when drawing drawings, do not know how to mark, can only be a simple draw a rectangular tunnel, and then open a few openings in it, write the various building materials needed, estimate the cost and so on.

In recent years, the population of Chang'an City has increased by two or three times, and there are more and more people with cars, and the road traffic pressure in the capital is much greater than in previous years, and the traffic pressure is still secondary, and the most important thing is the problem of parking difficulties, which is getting more and more serious, and it has reached the point where it must be solved."

Li Yu opened his mouth and said seriously.

Li An said happily: "King Guangping can check the information specifically for this plan, it is really a blessing for Datang, these drawings will be handed over to you, just now the news came from the R&D center, the Wanli Transsion plan has encountered difficulties again, and it has to be dealt with!" ”

After speaking, he said with a helpless wry smile.

Li Yu took the design drawing drawn by Li An, and at the same time took back the graffiti he had drawn, and said lightly: "The Tang Dynasty has made Li Shilang tired, but in the future, if you need the help of this king, just open your mouth, this king will go back to study the underground parking garage with his subordinates, and say goodbye." ”

Li An was also inconvenient to keep, personally sent Li Yu out of the door, and then took a sip of tea, and then set off for the R&D center, where the ongoing Wanli Transsonic Project is the most important work content of Li An, which will play a pivotal role in the development of the Tang Empire in the future.

Although Li Yu got Li An's drawings, but for this kind of underground parking garage plan that has no precedent in Datang, he must be very cautious and carefully discuss and study with his henchmen, and must take into account all the difficulties that the plan can encounter, and there can be no small mistakes, otherwise, not only will not only the opportunity to become famous be gone, but even, will be labeled as a loser forever, and an incompetent and failed emperor, for example, it is difficult to have a future, even, His incompetence will also lead to his crown prince father being implicated.

Some ministers would ask the emperor to remove the crown prince and replace him with a smarter prince under the pretext that the prince was dull and his son was even more dull.

There was already a precedent for this in the Jin Dynasty, the son of Emperor Sima Yan of the Jin Dynasty, Emperor Sima Zhen of the Jin Hui Emperor, was a fool, and his intelligence was much worse than that of ordinary people, which made Sima Yan very distressed, and he wanted to remove the prince and choose a smart son to be the emperor again.

But this stupid Sima Zhen's son, that is, Sima Yan's grandson, is exceptionally smart, which makes Sima Yan see hope, even if his prince's son is not good, but his grandson's IQ level is high enough, in this way, the future of the Great Jin Empire is still very promising, so that he did not abolish his foolish prince, and the ministers are also willing to let a fool be the emperor in order to better control the regime.

In other words, if Sima Xin's son is also stupid, then his position as the crown prince will not be kept, of course, for the Great Jin Empire, his position as the crown prince cannot be kept, which may be a good thing.

And Li Heng has been dodging like a turtle for fear of being accused of having other plans, and has never done anything with a level of ability, although he is still relatively smart compared to Sima Zhen, but it is not much higher, at least, in the eyes of many people, there are still many people who are smarter than Li Heng.

In this case, Li Yu's performance is very important, as long as he can show his intelligence and strong organizational skills, then he can win more fame for his crown father, so that the emperor has no reason to depose the crown prince.

Li Yu still needs to be busy for a while before he can propose to the imperial court to the emperor to build an underground parking garage, and Li An's construction of the Lishan breeding base can almost be implemented soon, after all, the Lishan Valley that Li An chose is a very inconspicuous place, and Li An's status is relatively high, as long as he proposes to build a research base for breeding wild animals, then, no one will stop him.

The instructive document was quickly issued, and after Li An got the permission of the document, he immediately asked the housekeeper to enter Lishan with a construction team of more than 100 people, accompanied by dozens of soldiers, who were mainly responsible for safety and security work.

Building the base requires a lot of materials, such as wood, bricks, concrete, steel, etc., among them, wood is a material that exists in the valley itself, but in order to protect the ecological environment of the valley, Li Ang decided not to use any tree in the valley, and all the wood was purchased from the market.

Breeding areas, accommodation areas, grain reserve areas, planting areas, watchtowers, etc., are very clearly marked on the map, and more than 100 craftsmen only need to build according to the information marked in various drawings.

In the interior of Chang'an City, because all the civil buildings can not exceed the walls of the imperial palace, therefore, there are almost few really tall buildings, in addition to the Big Wild Goose Pagoda, in addition, the houses of ordinary people, it is good to have three floors, and the houses of four or five floors are in the southern area of the capital far away from the imperial city.

And in the Lishan Valley, this situation does not exist, the valley drop is very large, even if a dozen high-rise buildings are built at the bottom, it is no problem, such a tall building, it can't even reach the height of the halfway up the mountain, let alone spy on the Huaqing Palace.

The high-rise building has a strong ornamental function, only need to build a ten-story high-rise building in the middle of the valley, then, standing on the high-rise building, can take in most of the situation of the entire valley, and this is undoubtedly a great benefit to management.

The lower floors can be considered for storing animal food, the higher floors can be converted into staff dormitories, and the highest floors are designed as observation decks, with nothing inside, surrounded by fences and glass, so that people standing on it can have a better view.

In addition, Ang Lee said that an ornamental aerial suspension bridge should be built, and this ten-story high-rise building can be used as the foundation pillar of the suspension bridge.

After much consideration, Ang Lee decided to design the high-rise buildings in the heart of the valley into 12 floors, each with a height of about 3 meters, so that the building has a total of more than 30 meters.

In order to facilitate the observation of the situation in the valley, the shape of the building is not square, but cylindrical, just like a tower such as the Big Wild Goose Pagoda, but the tower designed by Ang Lee is much stronger than the Big Wild Goose Pagoda and will not collapse for thousands of years.

The height of more than 30 meters is nothing, and what is even more remarkable is that the diameter of this tower is eight meters, which is much thicker than the Big Wild Goose Pagoda with a diameter of four or five meters.

At the position of the sixth layer in the middle, the suspension bridges are extended in four directions, and these suspension bridges gradually descend with a certain amplitude, and for safety, at intervals, there is a column, most of these columns are camouflaged reinforced concrete columns, and when there are tall trees, they will also be directly used, so that some columns can be saved, so as to save costs.

The height of the sixth-floor position is about fifteen meters, that is, the highest part of the suspension bridge is fifteen meters, and after gradually shifting downward, the height of the shortest part is only four or five meters high, and it is not safe to be shorter, after all, there are beasts below, and it is safer to be farther away.

The length of the suspension bridge is very long, the length of the four suspension bridges is about one or two miles, and it can continue to improve in the future and build more suspension bridges, while for the width of the suspension bridge, there is not such a high requirement, as long as two or three people can be allowed to walk side by side, and the width designed by Ang Lee is two meters.

When it comes to suspension bridges, many people's first impression is that they are simple bridges with wooden planks laid underneath and rickety when walking, just like the iron chain bridge like the Luding Bridge in textbooks.

In addition to the lowest high-rise buildings and columns, there are steel beams on both sides of the suspension bridge, and there are two small steel beams inward, and the horizontal road surface also has a steel beam at intervals, and the rest of the part is laid with wooden planks thick enough to support many people.

Such a project is not small, is it really enough for more than a hundred craftsmen? If all the parts were to be processed by craftsmen temporarily, it would definitely be too late, such as the wooden planks of the suspension bridge, which are in such a high demand that even if a thousand carpenters are found, they will be busy, and it will be even more time-consuming to build the steel beams on site.

Therefore, in order to build the breeding base as soon as possible, Li An decided to buy all the finished products, anyway, Li An is so rich that no matter how wasted, the money in his hand can not be spent, since he can pursue efficiency, why not pursue it?

And the reason why Li An can buy these ready-made materials is because after so many years of development, many industries in the Tang Empire have developed, and the finished steel beams have long entered the market, and the wooden planks of various lengths have long entered various carpentry shops, so that as long as you have money in your hands, you can easily buy these raw materials, so that you can quickly construct.

For example, Li An designed the span of the suspension bridge to be two meters, in addition to the width of two meters is enough to use, there is another reason, that is, the length of most of the wooden planks on the market is two meters, so that after these boards are bought, they do not need to be processed, and they are laid directly, and the requirements for labor are naturally greatly reduced.

As for the steel beams, it is formed with the more and more Datang Railway, and many businessmen see that the number of railways laid in the future will only be more and not less, so they buy iron materials to build rail steel beams, so as to earn a lot of processing fees.

Needless to say, the quality of the rails is needless to say, dozens of trains are running on it without pressure, let alone people walking on it, so there is no pressure to use the rails as the steel beams of the suspension bridge, and the progress of the construction is bound to be very fast.

In addition to these main buildings, there is a more important building, that is, the separation wall, although the valley is relatively closed, but there are also two directions of the slope that are not so steep, and there is a passage into the valley, these places must be dealt with, to ensure that animals such as wild boars cannot pass, only one gate is enough, to build a more imposing style.

After everything is ready, the next main task is construction, and since the construction requires a lot of materials, the requirements for transportation capacity are very high.

For this reason, Li An spent a lot of money to recruit a complete transport team, this team is very remarkable, with dozens of power cars, and hundreds of carriages, the transportation capacity is not ordinarily strong, usually the main business is to help large and small businessmen transport short-distance materials, and in order to prevent bandits from looting, the convoy also has special guards.

After more than 100 craftsmen were stationed in the valley, the transportation team also began to get busy, going to the markets inside and outside the capital every day to pull goods, and transporting all kinds of construction materials bought by Li An's housekeeper to the valley, so that the construction could be carried out normally.

Three days later, Li Ang decided to go to the valley to see how the construction was progressing, and the vehicle soon took Li An to the valley mouth of the valley, and at this time, the valley mouth had begun to build the courtyard wall and gate, the gate was very wide, enough for four cars to pass at the same time, and inside and outside the courtyard wall, a large number of building materials were piled up.
