The design of the Luoshui Bridge was definitely very advanced. It was the design of the bridge in the future, which was more than a thousand years ahead of the Tang dynasty. It was normal for it to be approved by Li Longji. There was nothing strange about it.
Of course, the Luoshui Bridge designed by Ang Lee was a low-end version. It could not be compared with the bridge in the future. It was only similar in appearance and design, but the scale and materials were far inferior.
But with the current conditions of the Tang dynasty, it was already very impressive to be able to build the bridge in the future. After all, material resources and materials were limited. They could only build a low-end version. Just like the train that was built before, it was also a low-end version. It could not be compared with the high-speed railway and shinkansen of the future.
Of course, even if it was a low-end version, it was absolutely high-end for the people of the Tang dynasty. At least, as the emperor, Li Longji already thought that the Luoshui Bridge was an extremely high-end bridge.
"Your Majesty, this is nothing. In the future, I will definitely design a more ingenious bridge, especially the one over the Yangtze River and the Yellow River. It must be built in the most magnificent and sturdy way."
After being praised, Ang Lee immediately became smug.
"Haha! Good! Assistant Minister Li, you must work hard. By the way, Assistant Minister Li, what suggestions do you have for the establishment of the Bridge Department? "
Li Longji asked.
Ang Lee thought for a moment and said, "Your Majesty, the Bridge Department's main responsibilities are divided into two parts. One is to organize a large number of craftsmen to build large bridges. The other is to maintain and maintain the built bridges. At the same time, it will collect a certain toll to make up for the financial losses in the construction of the bridges."
"Toll? How will it be collected? "
Li Longji was immediately interested when he heard that the bridge would be collected. Guo Xuji's eyes also lit up. This was an instinctive reaction to money. It was normal.
"Your Majesty, you can set up roadblocks on both sides of the bridge. All the carriages and pedestrians that want to cross the bridge must pay a toll before they can cross the bridge. Among them, the pedestrians and horses must pay less, and the carriages that transport goods must pay more. However, the cost must not exceed the shipping price at the dock, otherwise, the bridge will be built in vain. As for the trains, there is no charge, so as not to disturb the normal movement of the trains."
Ang Lee gave his suggestion.
"Good, Assistant Minister Li's suggestion is very good. The toll can gradually recover the cost of the bridge construction and greatly relieve the pressure of the following bridge construction. Moreover, it is cheaper than shipping, which can reduce the burden of pedestrians. Let's do it..."
Li Longji was overjoyed. In this way, the large bridges would become a money-making tool for the imperial court. In the future, the toll of the bridges would become a very important source of income for the imperial court of the Tang dynasty. Together with the railway system, it would contribute a steady stream of financial resources to the imperial court of the Tang dynasty and support the continuous operation of the imperial court of the Tang dynasty.
Later, Ang Lee gave the blueprint of the canal bridge to Li Longji and pointed out that the canal bridge was larger than the Luoshui Bridge. The amount of work required was about five times that of the Luoshui Bridge. It would require more manpower to complete as soon as possible.
Li Longji was of course very supportive of Ang Lee and immediately promised that no matter how much labor was needed to build the bridge, it would be directly drawn from the people near the bridge construction site. The imperial court officials at all levels would fully cooperate with the officials of the Bridge Department. Otherwise, if the construction period was delayed, they would be severely punished.
After leaving the Imperial Palace, Guo Xuji was very grateful to Ang Lee and implored Ang Lee to help the Bridge Department more so that he could make achievements.
Of course, Ang Lee would not refuse. He made it clear that it was his responsibility to build every bridge well. He would do his best to help the Bridge Department grow as quickly as possible and gradually get rid of their dependence on him.
After showing his token, Ang Lee smoothly left the city through the South Gate and went straight to the villa. At this time, it was already very late. Because he did not inform anyone in advance, no one in the villa knew that he would return at this time.
"Alang, why have you come back? This servant will go inform Madam."
Li Xiaoyin was in charge of the night watch. When she saw Ang Lee suddenly enter the main residence, she stood up in surprise and prepared to inform Yan Ruyu.
"No need. Right, it's so late. Madam hasn't slept yet?"
Ang Lee asked in confusion. It was already very late, and Yan Ruyu should be asleep.
"This servant is also not sure. Madam has been reading in her room the entire night. Just now, when this servant went to light the lamp, I saw that Madam's room was still lit."
Li Xiaoyin whispered.
"It's so late. Why hasn't she slept yet? Could it be that she sensed that I was coming back?"
Ang Lee smiled and strode into the courtyard of the main residence.
As expected, Yan Ruyu was still awake. Through the window made of tempered jade, he could clearly see Yan Ruyu's beautiful face. At this time, Yan Ruyu was sitting upright and reading, completely unaware that Ang Lee had returned.
Ang Lee was in no hurry to return to his bedroom. He quietly stood in the courtyard and admired Yan Ruyu through the window. The more he admired her, the more enchanted he felt. How could his wife be so beautiful?
"Alang, you've just returned. This servant will have the kitchen prepare some snacks!"
Li Xiaoyin walked softly to Ang Lee's side and whispered.
"No need. I'm not hungry. You rest! I'll go in and accompany Madam in a while. "
"Yes, Alang."
Li Xiaoyin responded and slowly retreated.
Ang Lee admired her for a full moment until he could not help but strode into the bedroom. He suddenly appeared behind Yan Ruyu and reached out to cover Yan Ruyu's eyes.
"Who, who is it?"
Yan Ruyu immediately turned pale with fright when Li An covered her eyes. However, when she saw that the person behind her didn't make any further movements, she calmed down and guessed, "Cao 'er, is that you?"
Ang Lee held back his laughter and kissed Yan Ruyu's ear intimately. He then bit Yan Ruyu's ear and held it in his mouth.
"Husband, it's Husband. Why did you suddenly come back?"
Yan Ruyu was very familiar with Ang Lee's strange hobby. Other than Ang Lee, no one else had done such a thing to her. Moreover, the numbing feeling of sucking was something only Ang Lee could do.
"It's not fun. It's not fun at all. You guessed it so quickly."
Ang Lee let go of his hands and bent down to rest his chin on Yan Ruyu's shoulder.
"Husband, it's really you. Why did you suddenly come back, and in the middle of the night?"
Yan Ruyu furrowed his brows.
"Your husband was going to repair the bridge at the Luo River, but I missed Madam too much, so I secretly came back. Madam is not sleeping in the middle of the night. Is it because you miss your husband too much that you can't sleep?"
Ang Lee joked.
"Husband is not serious as soon as he comes back. So annoying."
Yan Ruyu glared at Ang Lee, but her expression clearly revealed her excitement and ambiguity. Her handsome husband had come home. How could she not be excited?
"I've been holding it in for half a month. How can your husband be serious? Come! Let your husband pamper you. "
Ang Lee smiled naughtily and hugged Yan Ruyu tightly in his arms.
Yan Ruyu smiled. The corners of her mouth and the corners of her eyes were filled with an intoxicating charm. Her two jade-like arms tightly wrapped around Ang Lee's neck, assuming a posture of allowing Ang Lee to pamper her.
"Madam, did you miss me in this half a month?"
Ang Lee walked towards the bed and asked domineeringly.
"Husband, I really miss you."
Yan Ruyu's cheeks were crimson. She looked at Ang Lee with even more charm in her eyes. It seemed that she had long been prepared to be pampered by Ang Lee and was just waiting for Ang Lee to come home.
Ang Lee could not stand this kind of charming look. Moreover, this kind of look appeared on a beautiful woman like Yan Ruyu, which made it even more difficult for Ang Lee to control himself.
"Madam, you are really beautiful tonight, really beautiful."
Ang Lee said as he laid Yan Ruyu flat on the bed, and put his hands on Yan Ruyu's shoulders. He rubbed her clothes and slowly moved outwards, and very easily took off Yan Ruyu's clothes.
Next was the relatively rough sex. Ang Lee had been holding back for more than half a month, so he was still very angry. Of course, he couldn't care less about having tender feelings for the fairer sex. He had to satisfy himself first. Moreover, Yan Ruyu's expression was extremely intoxicated and didn't show any signs of being hurt. This made Li An even more unbridled and rude.
After late autumn, the weather was getting colder and colder, but this could not stop the enthusiasm of the craftsmen in the R&D Center. The production of various machinery was not affected at all. Moreover, with the introduction of more and more advanced steam machine tools, the construction speed of machinery was also continuously increasing, which greatly accelerated the industrialization process of the Tang Empire.
Ang Lee's enthusiasm for continuing to develop more advanced products did not diminish at all. According to his memory, he provided the craftsmen with ideas for improvement and research and development. He even drew drawings and asked the craftsmen to follow them.
Since the establishment of the R&D Center, Ang Lee himself did not know how many products had been developed. If all the products, large and small, were added together, it was estimated that there were hundreds of thousands of products. Of course, large-scale advanced machinery only accounted for a small number. Most of them were ordinary products that were not very advanced. The purpose of many products development was to be exported to western countries, so as to obtain enough financial resources to further revitalize the industrial economy.
For example, products such as glass balls with small animals in them, medicinal jade, small mirrors, and so on were very suitable for export. They could bring rich financial resources to the Tang Empire and Ang Lee.
Under the premise of more and more financial resources, all kinds of scientific research had made great progress. A variety of new products and improved materials had come out of nowhere one after another.
What particularly excited Ang Lee was the great progress made in steelmaking technology. After the emergence of concrete, blast furnaces could be made bigger and stronger, and the steelmaking technology was improved step by step, which greatly improved the hardness and toughness of steel.
The improvement of the performance of steel meant that more advanced machinery could be built. With less steel, more reliable parts could be built. Especially in the field of cannon casting, the thickness of the cannon barrel could be greatly reduced, and thus the weight of the entire cannon could be reduced. It was convenient for rapid mobile deployment.
In addition, the performance of steel and the use of metal cutting machines allowed Ang Lee to try to develop more advanced breech cannons, which would greatly improve the practicality of artillery.
The structure of breech cannons was not complicated. Ang Lee had wanted to build breech cannons for a long time. It was just that the performance of the materials and the processing machines was too backward. Now, the technology of steelmaking and the processing machines were developing rapidly. This made Ang Lee feel that the time to build breech cannons was ripe. In order to better display the power of the cannon and deter potential enemies, the development of breech cannons was put on the agenda.
All the technical talents involved in the development of breech cannons were talents who had previously developed cannons. Ang Lee trusted these technical talents very much. He believed that they would be able to complete the task of developing breech cannons.
Ang Lee drew all the parts of the breech cannons and asked these technical talents to build the cannons according to the drawings. They would continue to experiment until a usable breech cannons were built.
Ang Lee was very excited at the thought of the breech cannons being developed. This time, the breech cannons developed by Ang Lee were much better than the cannons that were already equipped with the army. There were many technical improvements.
First, the steel processing process with better strength was used to reduce the thickness of the cannon barrel, making the cannon lighter.
Second, the breech cannons were designed with a barrel, a breech cannons, and a valve. It was very convenient to load shells. Cleaning the barrel could greatly improve the firing speed of the cannon.
Third, the firing pin was installed at the breech cannons. In this way, there was no need to use the backward method of using torches to ignite the cannon. This would further improve the firing efficiency of the cannon.
Of course, the breech cannons technology was not the end. Ang Lee would continue to develop more advanced cannons, so that the cannon technology of the Tang Empire would make another big leap.
The talents in the development of breech cannons strictly followed Ang Lee's requirements. They carried out the development step by step. Any materials and equipment needed could be obtained immediately.
Ang Lee gathered some blacksmiths and began to develop iron wire, which would be in great demand in the future. He also used various types of iron wire to make spring materials of different thicknesses.
Whether it was iron wire or spring, they all had extremely important practical value. They were of great significance to the manufacturing and research of various machinery in the future.
The manufacturing process of iron wire was really not complicated at all. It was just burning iron until it was softened. Then, the softened iron was placed in a mold cavity. The mold cavity had a small opening. The softened iron was squeezed from the back, and the iron wire could be obtained from the small opening.
In order to preserve the newly made iron wire, a cylinder with a relatively large diameter was also needed to roll up the newly made iron wire.
The mold used to make iron wire must be heat-resistant. If it melted when it came in contact with hot iron, it would definitely not work. In addition, the strength of the mold must also be guaranteed. Otherwise, it would break when it was pressed from the back.
The material with the best heat-resistance was undoubtedly ceramics, and the material with the highest strength was steel. Therefore, Ang Lee's idea was to make a mold with a ceramic inner and steel outer wall. It was used to squeeze the softened iron and make the required iron wire. As for the large cylinder used to roll up the iron wire, ceramic materials would suffice.
