Li Longji has been accustomed to seeing new things invented by Ang Lee every once in a while, which makes his heart excited, but now, Ang Lee has not dedicated anything newly invented to him for a long time, which makes him a little surprised, and of course, a little unhappy.

Although he arranged guards around Ang Lee, these guards were not qualified to enter the R&D center, and they could only stay outside every time, so Li Longji only knew that Ang Lee was busy in the R&D center every day, but he didn't know what he was busy with.

After all, whether it is laying railroad tracks or R&D centers, there are shadows of officials from the Ministry of Industry, and both of these are inseparable from Li An, so these officials of the Ministry of Industry should know Li An's whereabouts and what they are busy with recently.

"Your Majesty, Li Shilang has been busy with the research and development of steam locomotives and laying railroad tracks recently, he has completely stopped going too far, he said that as long as the steam locomotive is successful, it will make earth-shaking changes in Datang, and the national strength will be greatly enhanced."

The official of the Ministry of Industry answered truthfully.

They also repeatedly proposed that Ang Lee inspect the railway lines, but each time Ang Lee used the extremely important reason for the development of steam locomotives that he would completely hand over the work of laying the rails to the officials of the Ministry of Industry, and he would only be responsible for the development of steam locomotives.

"Steam locomotive?"

Li Longji and the ministers all know that this thing is very important, but they have no knowledge of how powerful this thing is, and only after Li An invents it can they verify the great usefulness of this thing.

"How's the development progress? Did Li Shilang say when he will be successful? ”

Li Longji asked with concern.

"Your Majesty, Li Shilang didn't say a specific date, but Wei Chen looked at his expression and speculated that it was already soon!"

The Ministry of Industry official replied.

Li Longji nodded, for Li An's research and development project, he was unable to participate at all, so he could only passively wait for the results of the research and development, but fortunately, Li An was in the capital, under his nose, as long as Li An invented good things, he could be the first to know, so as not to let these good things out of control.

After continuing to emphasize the importance of the autumn harvest, Li Longji announced the dissolution of the dynasty and asked the officials to go and prepare for the autumn harvest.

Fifteen miles south of Chang'an City, Li Anzheng accompanied Yan Ruyu to take a walk in the orchard of the mansion, it was the autumn harvest season, and all kinds of fruit trees were full of attractive fruits, many of which were ripe and exuded an intoxicating fruity fragrance.

Yan Ruyu's belly is also quite bigger, and it can be seen at a glance that she is a pregnant woman, although it is a little inconvenient to hold up her big belly, but she still insists on going for a walk in the orchard.

Because of the smell of the fruity fragrance of the garden, she will feel very happy and happy, besides, there is Li Ang with her.

And because of the development of the steam locomotive, the time is relatively tight, so Li Ang can only come over to accompany her every other day, at dusk, and pick fruits to eat together.

"Madame, this apple is the largest in the whole orchard, come, give it to you."

Li An stretched out his hand and picked a relatively large apple and handed it to Yan Ruyu's hand.

"The biggest one? How can the husband be so sure, there must be something bigger above. ”

Yan Ruyu didn't believe that the apple she was holding in her hand was the biggest one.

"The one I picked must be the biggest, and if the lady doesn't believe it, she can pick a big one."

"You bully me, I'm like this, how do I climb trees, how do I pick fruits?"

Yan Ruyu was coquettish.

"Okay, if I find anything bigger than this, I'll take it off and give it to Madame."

Li An opened his mouth and coaxed.

"Husband, you used to be quite idle, why have you been so busy in the past few months, and will you always be so busy in the future?"

"No, I've been working on a big project recently, and I need to be there to supervise and urge me at all times, and it will be successful soon, and when the time comes, my Datang will undergo earth-shaking changes."

Ang Lee looked forward to it excitedly.

"The earth-shaking changes are going to succeed soon?"

Yan Ruyu is also very curious, he also hopes that his husband can benefit Datang and be a very useful person.

"Soon, if everything goes well, it is estimated that it will be in these few days."

In order to build a reliable steam locomotive, Ang Lee has spent a lot of time and energy, and has built more than a dozen locomotive test platforms, and each one is more complex than the other, and each is more advanced than the other.

The last two locomotives have been considered very successful, but there are still some deficiencies in reliability, and it is easy to break down on the way, which will inevitably greatly reduce the practicality of the train.

After making a full summary, Ang Lee found the problem, and spent a lot of time and energy to improve the problems, and now, the improvement work is in full swing, as long as a few key components are manufactured and assembled, the new locomotive is considered to be successful.

"The autumn harvest is coming, and the autumn harvest will soon begin, and before the autumn harvest, it is necessary to build a steam locomotive and immediately put it into the operation of transporting grain."

Ang Lee set himself the most basic goal.

Two days later, the R&D center finally came out with good news, the steam locomotive test was a complete success, the newly built locomotive, along the railroad tracks laid inside the R&D center, ran continuously for six hours, and there was no failure on the way, so far, the steam locomotive is completely built.

Because in the research and development process, a large number of tests have been done, so Li An knows where there will be problems in the steam locomotive, so he has prepared a large number of spare parts, and in case of failure, the parts can be quickly replaced, so as to ensure that the locomotive continues to move.

Of course, in order to prevent the locomotive from being damaged on the way, it is necessary to regularly inspect the locomotive systematically, and replace it in time as long as it is found that there are parts with serious wear.

The test was a complete success, all the talents involved in R&D and manufacturing, all of a sudden all boiling, for all the people involved in R&D, the huge role of the locomotive is naturally clear, they know too well the huge role of the steam locomotive, and even have the same longing as Ang Lee.

"The steam locomotive was built!"

"The steam locomotive was built!"

"Wow......"

The entire R&D center went crazy, and even the relevant departments participated in the celebration, and the cheers were higher and higher, and even the guards at the south gate of the capital could hear it.

"Congratulations to Li Shilang, it's finally done."

Yu Chaoen was originally urging the craftsmen to hurry up to build a solar cooker, but when he saw the cheers outside, he hurriedly ran out to see the excitement, although he still didn't know much about the steam locomotive, but he knew a little bit about the situation and understood that it was very powerful high-tech.

"Fish to make, the usefulness of this steam locomotive is far more than the solar cooker, and the profit that can be obtained in the future is far from being comparable to the solar cooker, haha!"

Li An smiled happily.

The success of the steam locomotive will inevitably become the main force of passenger and freight transportation in the future, and the profits will be astronomical.

Such an important inheritance, of course, cannot be taken by the family, otherwise, they are rich and rival the country, and it will be a huge threat to the imperial court, and handing over this property to the emperor and being controlled by the eunuchs can greatly weaken the benefits that the family may obtain.

Although the eunuch does not have a good bird, he will definitely embezzle from it and cause losses to the court, but the eunuch has no descendants and no family support, and it is not much fun to be too greedy.

The most important thing is that the eunuch is by the emperor's side, everything is under the control of the emperor, no matter how greedy he is, in the end he is just a fattened lamb, killing it, you can get all its property, and at the same time, it can also make the world applaud.

Li An's reminder has the meaning of letting Yu Chaoen be in charge of the railway work, after all, after such a period of observation, he found that Yu Chaoen's handling and management ability is still very strong, and the principle is not bad, even an old slippery head like Guo Ziyi has not been able to cheat things from him, and he is very suitable for being in charge of railway work, a large amount of money is controlled by Yu Chaoen, which poses no threat to the Tang Dynasty, and if the family is rich and rivals, it will be troublesome.

"What does Li Shilang mean is to let the little slave be responsible for the operation of the railway in the future?"

Yu Chaoen's heart pounded.

"That's right, this official can see that the fish envoy is still very capable, and if the fish envoy is in charge of the railway work in the future, he will definitely be able to reassure His Majesty."

Li An smiled at the corner of his mouth, hinting that he would support Yu Chaoen.

"Oops! If the little slave can really get this errand, Li Shilang will be the little slave's reborn parents. ”

Yu Chaoen was excited, and his speech was a little trembling.

"The fish envoy does not need to be excited, this matter will take some time, this official will personally meet His Majesty, and strongly recommend the fish envoy to be responsible for this matter."

Li An smiled slightly, reassured Yu Chaoen, and stretched out his hand to invite Yu Chaoen to celebrate the success of the steam locomotive with him.

Yu Chaoen was at a loss for excitement, and followed behind Li Ang and joined the celebration.

Due to the role of the steam locomotive, it was too big, and for this reason, the people who participated in the celebration were all indescribably excited, shouting, singing and dancing.

And in order to give them material rewards, Ang Lee ordered to slaughter pigs and cattle, buy wine and vegetables, and prepare to hold a big banquet in the R&D center.

Of course, there is no need for Li An to organize the banquet personally, naturally someone is in charge, and Li An must tell Li Longji the news of the successful test of the steam locomotive, and lead a group of people to test the railway at the north gate of Daming Palace as soon as possible, to see how many carriages the newly built steam locomotive can pull and how fast it can run after loading.

The celebratory banquet lasted for a whole day, and early on the second morning, Li Ancai led the relevant personnel to set off from the R&D center and transport the steam locomotive and a carriage to the north gate of Daming Palace along the railway track around the city.

Because this newly built railway track is from the R&D center at the south gate, it goes around a large station to the north gate of Daming Palace, for this reason, the speed can not be increased at all, and the test can not be carried out naturally, as for the straight railway line, the power of the steam locomotive can be better displayed.

"Li Shilang, the steam locomotive and the thirty carriages are ready, and now we can start the test."

Li An stretched out his hand and said, "Get in the car, get in the car." ”

As the supreme commander, Li Ang boarded the soft sleeper car at the front, and the accompanying personnel, some of whom were officials, some of whom were R&D talents, in short, were all figures with heads and faces.

All the curious people stood around, looking at the behemoth in front of them, and talking to each other about something.

"Get in the car, get in the car, and get ready to drive."

An official shouted loudly for the people involved to get into the car as soon as possible.

"Li Shilang, everyone has already gotten into the car, and the pressure hook has been completed."

Li An nodded and said, "It's okay, let's drive!" ”

"Filthy ......"

As the coal gradually filled the boiler, the train let out a loud roar, and slowly moved forward, driving the back carriages to the direction of Luoyang City.

Soon, all thirty passenger cars were driven, and the speed was gradually increasing, and at the highest time, it had reached the speed of the war horse.

In order to ensure the safety of the steam locomotive, Ang Lee designed the maximum speed of the train when designing and building, that is, it should not exceed about 40 kilometers per hour in later generations, and under normal circumstances, it is already very good to reach 25 kilometers per hour.

In this way, an hour is a hundred miles, and there is no pressure to travel thousands of miles in a day and a night!

The train runs very smoothly, through the side of the jade window, you can clearly see the yellow and bright millet fields on both sides, Guanzhong is the yellow earth, very suitable for planting millet millet, that is, the millet of later generations, also called yellow rice.

However, the yield of millet is not high, and it is simply not enough to maintain a large population in Guanzhong, especially in Chang'an City, where there are millions of people, and the demand for grain is extremely great.

Sitting in a fast-moving and smooth train, looking out the window at the large fields of mature millet grass, this feeling is very wonderful, and everyone in the train has this feeling of superiority.

"The autumn harvest is coming, the autumn harvest will be coming soon, and in a few days, you can see the busy scene on both sides."

"Yes! This year is another bumper harvest year, and the life of the common people is better. ”

"God bless Datang, my Datang is thriving everywhere now, and after the train comes out, it will be much more convenient for people to travel in the future."

Everyone muttered quietly.

"Li Shilang, I've already arrived at the Hot Spring Palace."

When Li An heard this, he raised his eyes and saw that the Hot Spring Palace was in front of him, and before he knew it, he had actually run seventy or eighty miles.

"Stop the car and get ready to return to the capital."

Ang Lee gave the order.

The steam locomotive came to a slow halt and, after a few hundred steps of gliding, came to a complete stop.
