The design idea of ​​the Luoshui Bridge is absolutely extremely advanced. This is the design idea of ​​the cross-river bridge in later generations. It is more than 1000 years more advanced than the Great Tang era. It is normal to be recognized by Li Longji. It is not surprising.

Of course, the Luoshui Bridge designed by Li An belongs to a low-profile version. It does not have comparability with the cross-river bridges of the later generations, but it is similar in appearance and thinking. The scale and materials are far from the same.

However, under the realistic conditions of Great Tang, as long as it can create the appearance of the cross-river bridge of later generations, it is already very difficult to deal with. It cannot be too demanding. After all, material resources and materials are limited, and only low-profile versions can be made, just like The previously built trains are also low-end versions, which are incomparable to later generations of high-speed rail and Shinkansen.

Of course, even if they are all low-profile versions, for people in the era of Great Tang, they are already absolutely high-end. At least Li Longji as Emperor already thinks that the Luoshui Bridge is an extremely high-end bridge.

“Your Majesty, this is nothing. In the future, This Small Official will definitely be able to design more ingenious bridges, especially those on the Yangtze and Yellow Rivers. Must build the most majestic and strongest.”

Li An was boasted a few words, and suddenly burst into anger.

“Haha! Okay! Minister Li has to work hard. By the way, Minister Li has any suggestions for the formation of Bureau of Bridges?”

Li Longji asked.

Li An thought about it, opened the mouth and said: “Your Majesty, the main responsibility of Bureau of Bridges, is divided into 2 parts, one is to organize a large number of craftsmen to build large bridges, 2 is to maintain and maintain the built bridges, and Charge a certain toll to make up for the financial loss of the bridge. “

“Toll? How to charge?”

When Li Longji listened to the bridge and charged fees, he immediately became interested, and Guo Xuji’s eyes also turned on. This is the instinctive reaction of people to money, and it is normal.

“Your Majesty, roadblocks can be set up on both sides of the bridge. All vehicles and pedestrians who cross the bridge must pay the toll before they can cross the bridge. Among them, pedestrians and horses pay less, and the carriage of goods should be charged more. The cost, but the cost cannot exceed the shipping price of the terminal, otherwise, the bridge will be repaired in vain. As for the passage of the train, there is no charge, so as not to interfere with the normal movement of the train. “

Li An gave his own suggestions.

“Well, Minister Li ’s suggestion is very good. The toll fee can gradually recover the cost of bridge construction, greatly alleviating the pressure on the next bridge construction, and the price is cheaper than shipping. . “

Li Longji is overjoyed. As a result, the large bridge has become an attractive Divine Item held by the Imperial Court. In the future, the toll of the bridge will become a very important source of income for the Great Tang Imperial Court. Together with the railway system, it will be Great Tang Imperial Court contributes continuously financial resources to support the continuous operation of Great Tang Imperial Court.

Subsequently, Li An handed over the drawings of the Canal Bridge to Li Longji, and pointed out that the scale of the Canal Bridge is larger than that of the Luoshui Bridge, and the amount of engineering is about 5 times that of the Luoshui Bridge. It requires more manpower to complete as soon as possible.

Of course, Li Longji strongly supported Li An and immediately gave a promise to build a bridge, how much painstaking effort is needed, and draw directly from the vicinity of the bridge to the civilian power. Officials at all levels of Imperial Court must cooperate with Bureau of Bridges officials, otherwise, the bridge will be delayed. The construction period is strictly punished.

After leaving Imperial Palace, Guo Xuji thanked Li An very gratefully and begged Li An to help the Bureau of Bridges work so that he could make achievements.

Of course, Li An will not refuse. It is clearly stated that it is his responsibility to build each bridge. He will do his best to help Bureau of Bridges, so that Bureau of Bridges will grow up as soon as possible and gradually break away from relying on himself.

After presenting his token, Li An successfully exited the city from the south gate and went straight to the other court. At this time, it was already very late, because not at all notified anyone in advance, so everyone in the other court I didn’t know that I would return at this time.

“Master, how did you come back, This Slave will notify Wife.”

Li Xiaoyin was in charge of the night. When Li An suddenly walked into the main house, he stood up in surprise, ready to notify Yan Ruyu.

“No need, by the way, so late, Wife hasn’t rested yet?”

Li An asked suspiciously, it was already very late, and Yan Ruyu should have fallen asleep.

“This Slave is also unclear. Wife has been reading in the house tonight. Just now This Slave turned on the light and saw that the light in the Wife house was on?”

Li Xiaoyin whispered.

“It’s so late, why don’t you sleep, do you feel I’m coming back?”

Li An smiled slightly and strode toward the courtyard of the main house.

Sure enough, Yan Ruyu hadn’t slept yet. Through the toughened Glassware windows, Yan Ruyu’s beautiful face could be clearly seen. At this moment, Yan Ruyu was sitting and reading a book without realizing that Li An had returned.

Li An is not in a hurry to return to the bedroom, just in the yard, quietly across the window, admiring Yan Ruyu who reads the book seriously.

“Master, you just came back. This Slave lets the chef prepare some snacks!”

Li Xiaoyin walked gently to Li An and whispered.

“No need, I’m not hungry, you rest! I will go in with Wife in a moment.”

“Yes, Master.”

Li Xiaoyin complied and slowly receded.

Li An admired for a full moment, until some uncontrollable, then strode to the bedroom, and suddenly appeared behind Yan Ruyu, reaching out to cover Yan Ruyu’s eyes.

“Who, who.”

Yan Ruyu was covered by Li An’s eyes, and immediately turned pale with fright. However, when he saw the person behind at not all further actions, he eased his mind, speculated: “Cao’er, are you?”

Li An resisted the smile and kissed Yan Ruyu’s ear, biting Yan Ruyu’s ear and holding it in his mouth.

“Husband, Husband, why did you come back suddenly.”

Yan Ruyu is familiar with Li An’s strange preference. Apart from Li An, not at all, anyone has done such an act on him, and the sucking numb feeling can only be done by Li An.

“Not good, it’s not fun at all, you guessed it so quickly.”

Li An released his hands and bent down to rest his chin on Yan Ruyu’s shoulder.

“Husband, it’s really you, why did you come back suddenly, and it was still in the big night.”

Yan Ruyu frowned.

“Wufu originally wanted to repair the bridge in Luoshui, but he missed Wife too much, so he ran back secretly. Wife didn’t sleep in the middle of the night. Did she miss her husband too much and couldn’t sleep lonely?”

Li An joked.

“Husband is not serious as soon as he comes back. I hate it.”

Yan Ruyu gave Li An a look, but the expression clearly revealed excitement and ambiguity. The handsome and handsome Husband came home. How could she not be excited?

“It’s been half a month, how can the husband be serious, come on! Let him be pampered.”

Li An grinned badly and held Yan Ruyu in his arms.

Yan Ruyu smiled, the corners of his mouth and eyes were full of intoxicating charm, two jade arms tightly embraced Li An’s neck, and took a posture that Li An was pleased with.

“Wife, this half a month miss me?”

Li An asked domineeringly as he walked towards the bed.

“Husband, people really miss you.”

Yan Ruyu’s cheeks were flushed, and the look towards Li An’s eyes were more charming. It seemed that he had already made preparations to be favored by Li An, waiting for Li An to go home.

Li An can’t stand this kind of charming eyes, and this kind of eyes still appear on the beautiful woman such as Yan Ruyu, which makes Li An even more difficult to control.

“Wife, you are really beautiful tonight, really beautiful.”

Li An said to put Yan Ruyu flat on the bed and put his hands on Yan Ruyu’s shoulders, rubbing the clothes and slowly moving outwards, and took off Yan Ruyu’s lapel very easily.

The next step is the rude pa pa pa exercise. Li An suffocated for more than half a month, is it getting angry? Of course, I did n’t care about what had tender, protective feelings for the fairer sex anymore. Say first to satisfy myself. Moreover, Yan Ruyu ’s expression is extremely intoxicating, not at all showing the look of being hurt, which further makes Li An more unscrupulous and even more. Rude.

After the late autumn, the weather is getting colder and colder, but this cannot stop the enthusiasm of the craftsmen of the Research & Development Center to work hard, and the production of various machines has not been affected at all, and as more and more advanced steam machine tools After being put into use, the construction speed of machinery is also continuously increasing, which greatly accelerates the industrialization process of the Great Tang Empire.

Li An ’s enthusiasm for continuing Research & Development ’s more advanced products has not diminished, and according to his own memory, he provided craftsmen with ideas for improvement and Research & Development, and even drew drawings to allow the craftsmen to follow suit.

Since the establishment of the Research & Development Center, Li An has not been able to figure out how many Research & Development products, large and small products are added together, it is estimated that there are a few 100 to 1000 kinds, of course, large advanced machinery only A small number, most of which are ordinary products that are not very advanced, and there are many products whose purpose is Research & Development for export and sales to western countries, so as to obtain sufficient financial resources to further revitalize the industrial economy.

For example, glass balls with small animals in the middle, Glassware Small Mirror and other products are very suitable for export, which can bring rich resources to the Great Tang Empire and Li An.

Under the premise of more and more financial resources, all scientific research has made great progress, and various new products and improved materials have been born.

What makes Li An particularly exciting is that steelmaking technology has made great progress. After the emergence of concrete materials, the blast furnace can be made larger and stronger, and the steelmaking technology has been improved step by step to make the steel hardness and toughness. Are greatly improved.

The improvement of steel performance means that more advanced machinery can be built, less steel can be used to build more reliable parts, especially in the field of cast guns, the thickness of the barrel can be greatly reduced, thereby reducing the weight of the entire artillery. Facilitate rapid mobile deployment.

In addition, the performance of steel and the use of metal cutting machine tools have allowed Li An to try the more advanced Breech Cannon of Research & Development, thereby improving the practicality of Artillery to a great level.

The structure of Breech Cannon is not complicated, and Li An has long wanted to build Breech Cannon, but it is suffering from the material and the performance of processing machine tools are too backward to be processed at all. Today, steelmaking technology and processing machine tool technology are developing rapidly This allowed Li An to see that the time to build Breech Cannon was ripe. In order to make better use of the formidable power of the artillery and to deter potential enemies, Breech Cannon’s development work was put on the agenda.

All the technical personnel involved in the development of Breech Cannon are all those who previously developed artillery. Li An trusts these technical talents very much and believes that they can certainly complete the task of developing Breech Cannon.

Li An painted all the parts of Breech Cannon, and let the technical personnel who develop the artillery build the artillery according to the drawings, and continue to test until the Breech Cannon can be used.

The thought of Breech Cannon is about to be developed, Li An is very excited. This time, the Breech Cannon developed by Li An is much better than the artillery that has been equipped with troops, and there are many technical improvements.

First, the use of stronger steel processing technology to reduce the thickness of the artillery barrel, so that the artillery becomes lighter.

Second, the Breech Cannon structure with a barrel, stern and gun valve is very convenient for loading shells and cleaning the barrel, which can greatly increase the firing speed of the artillery.

Third, install an ignition striker at the end of the gun, so that you don’t need to adopt the backward way of torch ignition, thereby further improving the efficiency of artillery shooting.

Of course, Breech Cannon’s technology is not the end, Li An will continue to develop more advanced artillery, which will allow the Great Tang Empire’s artillery technology to take another big leap.

The Research & Development talents of Breech Cannon, strictly in accordance with the requirements of Li An, are developed step by step, and any materials and equipment needed can be obtained immediately.

And Li An gathered some blacksmith talents and started to develop iron wires with great demand in the future, and used various types of iron wires to manufacture spring materials with different thickness.

Whether it is iron wire or spring, it has extremely important practical value, which is of great significance to the manufacture and Research & Development of various machines in the future.

The manufacturing process of the iron wire is really not complicated at all. It is to burn the iron block to the softened state, and then put the softened iron block into the mold cavity, the mold cavity has a small opening, and squeeze the softened iron block from the rear. You can get the wire from the small mouth.

In order to save these freshly made iron wires, a cylinder with a relatively large diameter is needed to wind up these freshly made iron wires.

The mold for making iron wire must be resistant to heat. If it melts when it touches the hot iron block, it will definitely not work. In addition, the strength must be guaranteed. Otherwise, it will break if you press hard from the rear, it will not work.

The best material for high temperature resistance is undoubtedly ceramic, and the material with high strength is steel. Therefore, the idea proposed by Li An is to make a mold with a ceramic inner shell and a steel outer wall, which is used to squeeze and soften the iron block. If you need the iron wire, the large cylinder used for winding the wire can be made of ceramic material.

The Great Tang is a big ceramic country. It is a piece of cake to make various types of ceramics. Therefore, it is not difficult to research and develop iron wire equipment. Just spend a little effort on Research & Development.
