Datang Nongsheng

Chapter 702 Promoting the Development of Science and Technology

Naturally, the steam engine is not so easy to build. Although most of the students who have studied in junior high school and high school in later generations know its principle, the current materials of Datang can basically satisfy the production of it.

However, it is one thing to understand the principle, another thing to make it, and another thing to make it and apply it in practice.

What is more depressing is that Sun Xiangfu has given back most of the science knowledge to the teacher. Therefore, each research institute can only explore and build something according to the direction he specified under the vague ideas he provided. And these things are now the things that the junior high school students in Jiuyuan County School like to play with most.

Perhaps, after Li Shimin truly ruled the world, this thing has not been built yet, and it is also possible that a talented person who can draw inferences in this respect will be able to make it soon.

In later generations, it took about 100 years from the first working model of the steam engine at the end of the 100th century to the final production of the steam engine that can be used in a wide range of industries at the end of the [-]th century, and more than [-] years from the beginning of the [-]th century In the meantime, British talents gradually manufactured textile machines driven by steam engines, ships, locomotives, and even locomotives. These things allowed them to quickly accumulate capital and eventually become a world power.

However, Sun Xiangfu knew that in the first nearly a hundred years of slow development, there was actually a long period of time in the blank period. Savelli manufactured a vacuum pump for mine drainage in 1698, but Watt did it in 66. It was not until 1764, a year later, that he began to study the transformation of the steam engine, and it took him only one year to transform it into a relatively modern version that can be widely used in industry.

Well, in Sun Xiangfu's view, it is not difficult to use its principle to make a working model machine and simple pumping equipment, and it is even not difficult to transform it into a model machine suitable for industry. If you do research, it can be done in two or three years at most. The difficulty is how to apply it scientifically to various industries and actually create benefits for the country.

Even Britain in the 100th century took about [-] years to apply it well. Although the current level of various industrial manufacturing in the Tang Dynasty has been greatly improved, it slightly exceeds that of the later Song and Ming dynasties. , but certainly not as strong as Britain in the [-]th century, at most comparable to the Qing Dynasty in the same period. It is no problem to make firecrackers, artillery and the like, but I am afraid that large steam vehicles and ships are not enough.

Then, it will take at least several decades to realize the industrial application of the steam engine.

Simply put, the Eurasian continent does not mean that it will be unified once it is unified. Even if the plan is promoted relatively smoothly, it will be difficult to get all of them without more than ten years. After all, Datang needs enough time to integrate them into the territory. For effective management of the land and people, at the very least, it is necessary to cultivate enough officials to govern these places.

Therefore, time allows it to come slowly.

Now that Sun Xiangfu knows that he will eventually come to this point, he can suggest to Li Shimin in advance to make some preparations in this regard, at least mobilize the people from the Western Regions to flow into the Anxi Metropolitan Protectorate, and build a bridge from Suiye City to Guanzhong. When it comes to concrete roads, the roadbed of the railway is also left out. Maybe a person like Watt will appear in Datang that day, and he will quickly fix it and put it into practical application!

The forward-looking nature of the traveler determined that Sun Xiangfu would not passively wait for Watt of Datang to appear. He brought this matter up and told Li Shimin that he wanted to mobilize all skilled craftsmen and everyone's top wisdom at the national level. To do special research, Li Shimin basically didn't think about his suggestion, so he agreed with a wave of his hand.

Therefore, soon there will be a team formed in Weinan with the junior high school students from Jiuyuan County School as the team and the top skilled craftsmen from all walks of life in Datang as the support. After that, they will specialize in the research and development and application of steam engines. For the materials needed, all factories must give priority to the supply in full amount with guaranteed quality and quantity.

Of course, when Li Shimin came here, he didn't just ask him for advice. He relied most on Sun Xiangfu's ability in agriculture.

"I originally wanted you to go to Liaodong to take over from Hongshen, but now it seems that I'm afraid it won't work. You have too many things to do in agriculture and planting, and you can't get away for the time being. If you can't solve the problem of eating more people , we in the Tang Dynasty will not be able to achieve great unification.

Therefore, in the next few years, your task is very heavy. In addition to continuing to study rice, you must also improve the varieties of new crops and spread them to the whole country. At least in places like Tamadao where there is a large food shortage, you need to plant them. High yield grain.

Later, I will give you a festival talisman that can pass through the whole country. With this festival, you can gather people in any state and county in the country, teach farming knowledge, and recruit local people. Where you think it is feasible, develop Planting specific crops, I want to see some results within three to five years, and within ten years, the cultivation level of the people across the country will not be inferior to the current Guanzhong. "

"Your honor." Sun Xiangfu bowed his hands and saluted.

The festival talisman that is popular across the country, and has the power to expropriate people and land across the country, this almost gives Sun Xiangfu the greatest convenience in promoting farming technology. With it in hand, Sun Xiangfu can go anywhere in the country, and the local government will To receive him with the standards of an imperial envoy, and to absolutely obey his orders in terms of agriculture, is the highest authority that cannot be higher.

"Besides, if you are walking in the local area, if you meet a talented person who can take on a big job, you can recommend it to the imperial court, and he will be appointed." After Sun Xiangfu accepted the errand, Li Shimin said with a sad face.

At this moment, Sun Xiangfu remembered that Li Shimin had just said that he would replace Zhang Gongjin, and asked, "Did Hongshen manage his subordinates well in Liaodong? How could your majesty think of replacing him?"

Li Shimin sighed and said, "Hongshen is capable of writing and martial arts, and has a big picture. He is naturally a good commander in charge, but his health is deteriorating. If I don't call him back for treatment in time, I'm afraid it won't last long. In addition, Keming, Shubao, Zhenghui and other veterans are also getting worse and worse. I can't just watch them die from exhaustion. The court's stall is getting bigger and bigger, and there is still a shortage of talents who can control one side."

Seeing that Li Shimin didn't even mention the samurai Xun who was a hypertensive patient, and Wen Yanbo who was dizzy at every turn, it can be seen how poor these people's health is.

In history, Du Ruhui and Zhang Gongjin, the samurai Xun, had already passed away during this period. Liu Zhenghui, the current governor of Huainan Road, will pass away this year. Qin Qiong will almost start to stay in bed this year, dragging on for two or three years, similar to Wen Yanbo. time to die.

And because Sun Xiangfu, the traveler, flapped his wings wildly, which greatly changed history, causing their lives to deviate greatly from history. In terms of living environment, diet, and medical conditions enjoyed, they were higher than in history. At least one or two levels of circumstances have caused their fate to change to a certain extent, at least they are not dead yet.

But many causes and effects were planted by Sun Xiangfu before he traveled, such as Qin Qiong's body, the extent to which he can make changes to such things is very small.

Now, due to the expansion of various aspects, Datang needs too many commander-in-chief talents. In the mainland alone, there are 10,000 state roads and two major capital guards. In terms of military affairs, there are [-] group armies, and they are not fighting outside the country. The [-] Nanya Forbidden Army, and the [-]+ City Guards in Chang'an and Jiangling, as well as ten ministers and officials in charge of national coordination in the Political Affairs Hall, calculated in this way, at least [-] top talents are needed. Enough, at present, but there is a big shortage, not to mention the situation that the territory and population will be larger after further expansion.

Therefore, Li Shimin is eager to seek talents now, and he likes talents like Sun Xiangfu, that is, talents who can do practical things, so he thought of asking Sun Xiangfu to recommend some.

Generally speaking, Li Shimin still misses the old officials who helped him a lot in the process of achieving his great cause. After being reminded by him, Sun Xiangfu remembered that he hadn't visited Qin Qiong for a long time. At that time, he should be in Jiangling City, but he will go to visit some other day.

However, when it comes to talents, Datang is not without it. Sun Xiangfu quickly thought of a young and strong man who could succeed Zhang Gongjin, and said, "You can keep Liaodong without any worries."

Li Shimin laughed when he heard the words, "Hehe, you have been in the court for many years, and you have talents, and you have always recruited your subordinates. I guess, the person you recommended is Su Dingfang who used to lead the Anbei Army under your subordinates!"

Being guessed by Li Shimin, Sun Xiangfu didn't blush at all. His subordinates have no talents, so what should they do?This is all due to previous work needs.

Su Dingfang is a relatively good military commander. He has inherited more than [-]% of Li Jing's commanding ability.

Therefore, Sun Xiangfu put away the embarrassment of being guessed, nodded with a serious face, and said, "Exactly, this man is rigorous in running the army and has excellent martial arts skills. He also performed outstandingly in the Battle of Liaodong and made great achievements. The leader is convinced of him, and in terms of prestige, he is enough to rule the town. However, if he is a governor, he must not only manage the military, but also manage the civil affairs. He has never been in charge of the civil affairs. It can be seen that His Majesty can send him a long history in charge of civil affairs."

Hearing this, Li Shimin nodded and said, "Well, in fact, Hongshen also recommended him to me before, this time he came to Jiangling, he left Su Dingfang to manage the place in Liaodong, and I will let Hongshen go directly to Shanxi later. Yang cures the disease, and ordered Su Dingfang to take over on the spot, as for Chang Shi! There are a few candidates available, I will think about it again."

The people in the court who want to say that their rank has reached this position are actually Chu Suiliang, Yu Wenjie, Zhang Xingcheng who served as long history and governor in Anbei Dadufu. In addition, there is a younger echelon, that is, Shangguanyi. Liu Yong, Li Yifu, Lai Ji, and Lai Heng are only in their 20s, and they have already mixed up to the level of Zhongshu Sheren, who can usually contact the important tasks of the central government.

Seeing Li Shimin's tangled look, I'm afraid he will send these younger people there, because it would be a waste to let Chu Suiliang, Yu Wenjie, and Zhang Xingcheng go. The position of Shangshu is the position of the chief executive of state roads. After all, the imperial court is now too short for top-level officials.

After hesitating for a moment, Sun Xiangfu put forward some thoughts that he had in mind, "Your Majesty, it is not a long-term solution to send one person to control a state road to manage the army and the people. If the opportunity is right, reforms should be carried out."

"I'm also considering this. At present, this is the only way to go. If I want to manage all the places like Guanzhong, Shannan Road is so detailed, it needs too many officials and manpower. I'm afraid, at least two It can only be done after three imperial examinations. However, since Zhengming proposed it, what good suggestions do you have?" Li Shimin asked helplessly.

The big border towns in the Tang Dynasty all have the characteristics of large land, large population, and far away from the center. In Andong, Anxi, Lingnan Road, and Nanzhong, if the chief official of any place has a different heart, it will not be so difficult. It is easy to control, at least one nationwide battle of tens of thousands of people must be launched before it can be wiped out. Sometimes, it is not because the people want to rebel so much, but because the current officials have too much power, which stimulates their ambitions. After that, they will use various means to incite the people to rebel with them.

In the Tang Dynasty in history, the emphasis was on the outside and the inside was light, which led to the Anshi Rebellion, and the separatism of the feudal towns appeared, from prosperity to decline. How stupid is Li Longji, so that the people in the Youyan land of Hebei at that time could not survive? ?Not necessarily, but the current governors, An Lushan and Shi Siming, can easily make their troops and people follow them to revolt. The good things are all the responsibility of the court and the emperor, and the good things are all my own credit.

When Datang was strong enough to a certain level, the outside could not defeat it at all, but the inside could easily destroy it and make it decline.This point is actually common in that dynasty. This nation has the most hard-working people. Under normal circumstances, as long as those in power do not commit suicide, they will not die. Often it is internal corruption, land annexation and other issues that harm the people. the whole nation.

Sun Xiangfu smiled and said, "Just now I said that relying on science and technology can help govern, but in fact, it still works when dealing with such problems. In addition to the system that can separate the military and the government from the border towns, the center also needs For the border towns, maintain an absolute advantage in force, so that they can't afford to rebel."

In later generations, in a big country, the president will usually hold the nuclear button, which is an absolute advantage in force. In contrast, the sergeants in the border towns of Tang Dynasty are equipped with the same equipment as the center, all of which are armored and steel knives. Certain advantages, that is, in terms of horses and ships, they can have a stronger advantage in mobility than the center. After all, Guanzhong is full of fields and forests, and it is impossible to raise too many horses. , the high-quality horses in Dingxiang Road are ten times more than those in Guanzhong, and the sea ships in Lingnan are also several times more than in Guanzhong. Not to mention the fire on all sides, even if there is a rebellion in one direction, it is difficult for the central government to quickly control the situation. It's easy to get out of hand.

"Absolutely, the advantage of force that makes them unable to rebel? You mean gunpowder, shouldn't I equip it to the troops in the border town?" Li Shimin roughly figured out the problem.

Sun Xiangfu nodded and replied, "If it is not necessary, there is really no need to equip the border town. Even if it is equipped, it is a very small amount of equipment. It is enough to ensure a decisive defensive effect. The absolute force mentioned by the minister The advantages are some more advanced military application technologies similar to gunpowder application and hot air balloon application.

Your Majesty, the function of gunpowder is not as simple as igniting or exploding. From a scientific and technological point of view, it can actually use its instant burning impact and blasting ability to create many weapons that are so powerful that the army of swords, guns and armor cannot resist them. Weapons, the imperial court only needs to develop such weapons and ensure that the center has an army equipped with such high-end weapons to keep crushing the military forces of border towns. However, how to use gunpowder to make more advanced weapons requires various methods. science and technology to advance research. "

Sun Xiangfu doesn't think that Li Yuhua can produce artillery, rockets and other things with black, fire, and medicine. In fact, so far, after knowing its explosive strength, it has been focusing on production and bombing. Medicines, bags, and explosives, medicines, cans and other things, these things are indeed not weak in terms of momentum, but in actual effect, they may not be very powerful. Song had a firearms supervisor, but it was defeated by Liao, Jin, Mongolia human hand.

The Ming Dynasty had a large number of artillery equipment, but they were suppressed and beaten by the Qing Dynasty, and finally the capital was destroyed by the peasant uprising. This is the reason why they did not really display the power of firearms.

Cannons, and even guns and other weapons, must be smelted and combined with mathematics, physics and other knowledge to produce things. If he is allowed to develop passively, I am afraid that after 200 years, it will still be the same as it is now. However, Give it to students like Jiuyuan County who have mastered relatively advanced mathematics and physics knowledge to take the initiative to study. In fact, it will not take long for it to achieve progress and continue to improve.

As long as the center of the Tang Dynasty guarantees an absolute advantage in force over the border towns, after the realization of the great unification, it can maintain absolute rule over the world for at least several decades. As long as there are two or three generations, it is enough for everyone in Eurasia Entering an era of common Chinese characters and Chinese, after all, under the current world environment, even the Tang Dynasty, which pays great attention to cultural education, has just achieved a literacy rate of more than [-]%, not to mention that those civilizations are far behind the Great Tang Dynasty. The countries in the Western Regions of the Tang Dynasty now teach them to learn Chinese. The difficulty of Chinese characters is actually the same as that of teaching the local minority people in the Tang Dynasty. As long as they are willing to spend some money, it usually only takes two or three years to produce results.
