In the ancient feudal dynasties, agriculture occupied the most core position, but agriculture also belongs to the industry of watching the sky and eating. Pen & Fun & Pavilion www.biquge.info

Therefore, since ancient times, the feudal dynasty has attached great importance to the wind and rain, and sacrificed every year, praying that the heavens can adjust the wind and rain.

Of course, in addition to sacrifices and prayers, the feudal dynasty also attached great importance to the construction of water conservancy to fight against disasters and reduce the losses caused by disasters.

In the pre-Qin period, there was a saying that Dayu controlled the water, in order to control the floods of the Yellow River, the Qin State built the Zhengguo Canal for agricultural development, and the Dujiangyan was built in Shuzhong, and the Tang Dynasty also set up a special government department to supervise the water conservancy, which was responsible for the construction of water conservancy and other matters, which shows the importance of agriculture.

As long as it is invented, it will make a huge contribution to the drought resistance and harvest protection of the Tang Empire, and it can also facilitate the daily agricultural irrigation of the people, and even, many high-lying fields in the south of the Yangtze River can also be planted with rice, thereby increasing the total output.

Under such circumstances, how could Li Longji not be excited?

"Ploughing machinery and pumping machinery are extremely important to my Datang, Li Shilang only needs to do his best to research and development, and I will let the Dushui Superintendent dispatch people to assist Li Shilang."

Li Longji thought for a moment and made the decision to let the water supervisor assist Li An.

"Your Majesty, now there are more and more talents in the R&D center, and excellent craftsmen from all over the country are gathered here, but in the future, my Datang will need more and more talents, and the talent gap is huge, so Weichen feels that it is necessary to expand the number of apprentices and let more people learn skills such as machinery."

Ang Lee suggests.

"These are trivial things, as long as you can survive, there will naturally be many people who are willing to learn to make machinery, Li Shilang has full authority to deal with it, I support you."

"Thank you, Your Majesty, Weichen will definitely do his best to create more useful things for the Tang Empire."

Ang Lee happily replied.

Along the way, in addition to the scene of cultivated land, that is, the lofty mountains and the yellow leaves, the scenery is absolutely first-class, Li Longji is overjoyed to see it, and the ministers and others accompanying him are all in a happy mood.

It's nice to be able to sit in the middle of a train and watch the scenery move out the window.

After arriving in Weinan County, Li Longji was a little tired, so he returned to the third carriage and lay down to rest, while Yang Yuhuan waited on the side.

At noon, the train arrived in Tongguan, and the dining cars of each train delivered the prepared meals to each carriage respectively, so that everyone could eat lunch in time.

Different identities, of course, the standard of meals is also different, Li Longji's meals are similar to those in the palace, eight vegetarian and eight meat, while ordinary eunuchs and palace maids only have one meat and one vegetarian and two dishes.

Sitting in the bright train car to eat, looking at the rolling Yellow River outside the window, everyone's mood is very heroic, and they all enjoy the rivers and mountains outside the window while eating.

The train never stopped, has been along the tracks, running to the direction of Luoyang City, after passing through Shaanzhou, Xiashi, Xin'an, and finally arrived at Luoyang City Railway Station in the evening.

A few days ago, when Li An came to inspect, there was no fanfare, only the employees of the railway station made preparations, and this time the emperor came in person, of course, the situation was different.

At the moment when the train stopped steadily, Li An lifted the curtains and saw that outside the train, the officials of Luoyang City, large and small, all stood respectfully to greet him.

The freight train carrying the royal belongings was one step ahead, so when Li Longji's royal special train arrived at the Luoyang City Railway Station, the chariot and the royal carriage were ready.

After some etiquette, Li Longji led the ministers into Luoyang City and went straight to Shangyang Palace.

Different from the three palaces of Chang'an City, Luoyang City has only one Shangyang Palace, which was built by Tang Gaozong Li Zhi in order to move the capital to Luoyang.

In addition, the scale of Luoyang City is also smaller than that of Chang'an City, and in terms of scale, it seems that it is always overpowered by Chang'an City.

However, some of the advantages of Luoyang City are incomparable to Chang'an City, that is, after the opening of the Grand Canal, the convenience of transportation has made Luoyang City more and more prosperous, and various materials are much richer than Chang'an City.

During the Wu Zetian period, Luoyang City was changed to the divine capital to highlight the status of Luoyang City, and Wu Zetian decided to build the capital in Luoyang City, because it was so convenient.

First, the Tang Empire was laid down with the help of the Guanlong military group, but after the founding of the People's Republic of China, the Guanlong nobles have been controlling the government, posing a great threat to the emperor's imperial power, in order to weaken the influence of the Guanlong nobles, the most effective way is to move the capital away from Chang'an City and go to Luoyang.

Second, it is the transportation convenience factor just mentioned, the Sui Dynasty developed the Grand Canal, so that a large number of materials from the northeast and south of the Yangtze River can be easily transported to Luoyang City, so that Luoyang City has become a transit base for the exchange of materials between the north and the south, in this way, it is bound to drive the prosperity of commerce, and the national capital must of course choose the most prosperous city.

Third, in the center and the world, with the territory of the Tang Empire at that time, Luoyang City was geographically the center of the entire empire, and the location of Chang'an City was a bit westward, which was not conducive to the control of the eastern rivers and mountains.

Fourth, the need for national defense, at that time, the eastern rivers and mountains have been stabilized, east of Luoyang City, until the sea, are the land of the Tang Dynasty, there is no strong hostile forces, the capital will not be raided, and there is a powerful Tubo Empire in the west of Chang'an City, once the Tubo army advances eastward, the capital Chang'an will soon be threatened.

Fifth, the food crisis, during the Qin and Han dynasties, the agriculture in Guanzhong was very developed, but after several wars, agriculture was greatly damaged, especially after the war in the Sixteen Kingdoms of the Eastern Jin Dynasty and the end of the Sui Dynasty, the soil and water were seriously eroded, the loess desertification, the sediment content of Jingshui and Weishui increased greatly, and the irrigation role was increasingly reduced, the irrigation capacity of the Zhengguo Canal in the Tang Dynasty was less than a quarter of the Qin and Han dynasties, while the population of Guanzhong was gradually restored, becoming the most populous northern hinterland, although Guanzhong was still called fertile in the Tang Dynasty, However, the grain that can be produced is no longer enough to meet the needs of the capital Chang'an, and the grain of Luoyang City is difficult to transport into Chang'an, so in order not to compete with the people for food, so it was decided to move the capital.

Sixth, hiding from the undead, this is a legend, according to legend, after Wu Zetian cruelly tortured and framed Queen Wang and Concubine Xiao Shu to death, his heart was very uneasy, and he often dreamed that Queen Wang and Concubine Xiao Shufei were dismantled, bleeding all over their faces, and the shadow of their teeth and claws made her frightened, in order to avoid the souls of these two people, Wu Zetian had to leave Chang'an City.

Of course, the legend is something that cannot be determined, but as an old woman who has survived in the palace for decades, the cruel experience must be extremely rich, the palace of Chang'an City, not only gave her Ganlin, but also gave her bitter water, leaving the sad place of Chang'an City, to Luoyang City, eight hundred miles away, will naturally make Wu Zetian feel peaceful and comfortable, in addition, comprehensive in all aspects, it is more beneficial to move the capital to Luoyang City.

Tang Xuanzong Li Longji decided to move back to Chang'an City, because in the 22nd year of Kaiyuan, Prime Minister Pei Yaoqing proposed a sectional transshipment method to transport grain, which was to set up warehouses at the confluence of the Yellow River, the canal and Weishui and the east and west of Sanmenxia, and the grain was first imported into the east warehouse, and then the mountain road was opened for 80 miles, and the land was transported to the west warehouse, and finally the grain was transported to Guanzhong.

In this way, the transportation date was greatly shortened, the transportation efficiency was improved, and the cost of grain entering Guanzhong was greatly reduced, which laid the foundation for Li Longji's return to Chang'an City.

Of course, at this moment, the railway has been built, and transportation has become faster, and in the future, Guanzhong will not be short of food.

With the current national conditions of the Tang Dynasty, Li An believes that Chang'an City is the best capital, although Luoyang City is the geographical center of the empire, but this is only the current situation, the Tang Dynasty has a railway, and can continue to expand the living space to the west in the future, while the east is already close to the sea, it is difficult to continue to expand the living space.

Li Longji visited Luoyang City this time, and initially decided to stay for half a month, and then return to Chang'an City after half a month, and in this half a month, the railway operation will be opened to facilitate the lives of the people.

However, the royal royal train and the two aristocratic special trains are not within the scope of operation, the royal royal special train is the emperor's personal train, and at any time, it will not be put into commercial operation, and the two aristocratic trains will resume operation after Li Longji returns to Luo Chang'an City.

In half a month, Li An was in Luoyang City, and that little life was quite nourishing, and when he had nothing to do, he went out of the city to play in the mountains and rivers, of course, he had to go out in the name of inspecting the road, otherwise, Li Longji would be blamed if he could not find himself, and as long as he showed the name of inspecting the road, Li Longji would feel that Li Ang was looking for a route for continuing to build the railway in the future, and he would naturally not be angry in his heart.

Through this half-month inspection, Li An found that the material reserves of Luoyang City are indeed much richer than those of Chang'an City, and the bulk commodities of Jiangnan and Northeast China will stay here in Luoyang City for exchange and transshipment, and the economic strength is not weaker than that of Chang'an City, but because Chang'an is the capital, it can suppress Luoyang in terms of status.

Luoyang City is a good place, very suitable for the national capital, but it is a pity that it is farther away from Anxi, which is not conducive to the westward expansion of the Tang Empire in the future, otherwise, Li Anzhen will persuade the emperor to move the capital.

After half a month of inspection, Li Longji got on the train and returned to Chang'an City with satisfaction, and immediately decided to come to Luoyang City again in winter to inspect in order to enjoy the unique beauty of Luoyang City in winter, and of course, the scenery along the way was also very good.

After having the railway system, it has become extremely convenient to visit Luoyang City, and it is not bumpy to sit on the train, and the facilities in the car are also extremely luxurious, very comfortable, and the speed of travel is also very fast, and it will arrive at the destination in half a day.

In later generations, the traffic conditions were greatly improved, so it caused a tourist fever, both the old and the young like to take advantage of the holidays to travel, see the outside scenery, adjust the mood.

In the era of the Tang Dynasty, due to the inconvenience of transportation, most people are not qualified to travel far away, and only those noble children with good conditions will ride horses to go on outings to see the outside world.

But now that the railway system has been successful, in the future, the people will become easier to travel, and the tourism boom may gradually develop, provided that the people's life is getting better and better, and they have enough spare money to travel.

After all, half a month has passed, many deciduous trees have become more bald, and more fallen leaves have piled up on the ground, which looks more desolate and has more autumn flavor.

Along the way, passers-by can occasionally be seen, and they all look at the high-speed train with curious eyes, as if they have seen a very novel monster.

After the emperor returned to Luoyang City, except for the royal train that was well preserved in the railway station of Chang'an City, the remaining trains began to be put into operation to facilitate the daily life of the common people.

Ang Lee, on the other hand, rushed to the R&D center and began to organize relevant technicians to conduct detailed research on the machinery for cultivating land and pumping water.

In his previous life, when he was a child, there were many pumping machines in the countryside where he lived, and the water source of the lake was sent to a higher position to irrigate the farmland that needed to be watered.

As for the tractors for ploughing, there are even more, and when it comes to the spring ploughing and autumn harvest seasons, the rice fields are full of tractors busy.

Long-term contact made Li Ang deeply impressed by these two things, and when he was in college, he learned a lot of common sense of mechanics, and the principles of these machines were clearer, so it was easy to draw the most basic drawings.

Of course, since there is no electricity and diesel at all, only the steam engine, the manufacture of these two things still needs to be greatly improved, and the size of the final product may be much larger than the two things in later generations.

Li Ang felt funny at the thought that the cultivator he could develop would be even larger than the combine harvesters of later generations, but as long as he could build it, it didn't matter if he was bigger.

After the weather turned cold, the vegetables in the open air gradually could not survive, and it was time for the vegetable greenhouse to show its might, for this reason, while developing the cultivator and pumping machine, Li An was also very concerned about the improvement of the 500 acres of vegetable greenhouses near the courtyard.

In order to better adapt to the growth of vegetables, Li An's vegetable greenhouse has 100 acres of modernization and modification, mainly to replace the silk with a new invention of tempered glass, which is not very good for heat preservation and light transmission, which will be more conducive to the growth of vegetables in the greenhouse.

In addition to Li An, there are some nobles in Chang'an City who also learn to build vegetable greenhouses, but most of them use silk with poor thermal insulation effect.
