This question is a bit hard, Zhang Yi shook his head directly, and said, "I don't know!" ”

Xu Pu looked at Yang Shan and Cao Nai again, and the two of them also shook their heads, no way, they really don't know.

It is no wonder that, apart from the Academy of Sciences, most of the Manchu officials only knew that science and technology were very good and powerful, and as for some specific working principles, they were not clear.

Xu Pu didn't sell Guan Zi either, and said: "It's better to answer the official, first of all, food!" ”

When the three of them heard this, they all frowned, didn't the steam train be built with steel, but food?

Seeing this, Xu Pu explained: "If you want to develop science and technology, you first need a lot of manpower, and the people of the world are bound to the land, so naturally it is not possible, so the emperor will spend great efforts to clear the acres of land, improve the tax law, and at the same time introduce improved seeds, increase grain production, and free a large amount of manpower from the land." ”

"The next step is steel, if you want to make steel, you need iron ore and coal mines, from exploration to development, to transportation, this process not only requires a large number of survey technicians, but also requires more manpower to excavate and mine."

"Now that we have steel, we can start assembling ...... Of course, the premise is that there are design drawings, assemble according to the drawings, and then a large number of experiments, constantly find problems, and find solutions to problems, still need a large number of scientific researchers, to be proficient in arithmetic, physics, chemistry and other complex knowledge. ”

"If you want to accomplish this, you need countless amounts of silver, and for example, every test is equivalent to throwing silver into the water and then ...... Poof, listen to it, it's gone! ”

"The three adults know that the research and development process of the first steam locomotive, in addition to a large number of iron ore and coal mines, also included hundreds of workshops that made accessories, and a total of tens of millions of taels of silver were smashed in!"

"However, all this also needs to be built on the element of luck, if you are unlucky, you have lost many battles, or you have never found a breakthrough in some technical problems, the cost will be more, it is possible to triple or even ten times!"

"The technical problems are very complex, and the correlation between many links is very strong, and in the process of testing, as long as one link goes wrong, all the previous efforts are in vain, and everything has to be reversed!"

"Three adults, do you still think it's easy to build a steam locomotive?"

Zhang Yi listened carefully, nodded again and again, and said, "You mean that even if a Kaneliang brings the drawings back to the Wa Kingdom, they won't be able to build a steam train?" ”

"Exactly!"

Xu Pu continued: "Not to mention the steam train, even if the rails laid under the train look simple, it is nothing more than making steel into a track and laying it on the sleepers, in fact, the technical content in it is very high, and the land of the Japanese country is not able to be built even if it is poured into the power of the country!" ”

Zhang Yi couldn't help nodding and said: "In any case, these new technologies are better to be less accessible to outsiders, so it is better to prevent problems before they happen!" ”

"Xia Guan thinks that in fact, it is not a bad thing to let them have proper contact."

"How?"

Xu Pu said: "Science and technology will develop sooner or later, and it is the next policy to strictly guard against it." ”

Zhang Yi asked rhetorically: "In this way, do you still have a good strategy?" ”

Xu Pu smiled slightly and said: "When the foreigners come to Daming, they will definitely feel shocked when they see the railway network extending in all directions, and there are steel giants spitting billowing smoke, carrying countless people and goods passing through quickly, and then they will feel thirsty!" ”

"It's this reason, and Ichijo Kaneliang also has this idea."

"Then let him have a good visit, and when he returns to China with reverence, he finds that his domestic industrial base is too poor, there is no steel, no coal, no talent, at this time, they want to build a steam locomotive, the only way is to ask for help."

Zhang Yi frowned and said: "How can the important weapon of the country be easily given to others?" ”

"Eh, Zhang Butang's pattern is small!"

Xu Pu waved his hand and said, "You can give it, but you can't give it for nothing." ”

"The ambition of the wolf son, if they learn the technology and turn around to deal with our dynasty, wouldn't it be a problem to raise tigers?"

"Zhang Butang exalted them, they are not tigers, at most they are just a group of white-eyed wolves!"

Xu Pu smiled and continued: "Steel can be sold, coal can be sold, but technology can't be sold, we can send someone to help them build trains, or sell the finished product directly to them." ”

"The steam train is not finished after it is built, if it wants to operate normally, it needs a lot of coal, and the country does not produce coal, so it can only continue to import from our country, and the follow-up maintenance of the train also needs a lot of steel, and steelmaking needs more coal."

"As long as these materials are firmly controlled, it is equivalent to grasping the lifeblood of the Wa Kingdom, let them go east, and never dare to go west!"

Zhang Yi finally reacted, this trick is amazing!

The people of the Academy of Sciences not only have a set of inventions, but also play tactics that are not inferior to anyone.

These methods are so clever that even Confucian students who are familiar with the Spring and Autumn Period and are well versed in the way of comprehensive cultivation do not necessarily have such a strategic vision.

Yang Shan had a different idea and asked: "If it is really as Xu Shiyu said, the Wa State is completely dependent on the resources of our dynasty, and it can fundamentally control them, but if the Wa State does not want to be controlled and takes the initiative to give up these resources, won't Fang Cai's words become empty talk?" ”

Xu Pu said with a smile: "When a person has tasted the delicacies of the mountains and seas, and then let him go back to the days when he ate bran vegetables, he will definitely refuse, and the same is true of the Wa Kingdom, as long as they taste some sweetness, they can then give it what they want!" ”

Yang Shan didn't speak anymore because he had nothing to say.

What shocked him even more was that Xu Pu's qualifications in the Academy of Sciences were not deep, or even very shallow, and before the orthodox nineteen-year imperial examination, he had been reading the Four Books and Five Classics, and it was only a year since he turned to study natural science.

I really didn't expect that in just one year, there was such a deep insight into the bottom, and there was such a deep scheming, could it be that those who engage in science should learn the Art of War every day?

Cao Nai said earnestly: "Listening to your words is better than reading for ten years, and the old man has been taught." ”

Xu Pu hurriedly said: "Don't dare to be, don't dare to be, Cao Gong tortures me!" ”

Cao Nai smiled faintly and said: "The future is terrifying, seeing that there are successors to the Ming Dynasty, the old man is relieved!" ”

Xu Pu clasped his fists and saluted again and again: "The younger generation is ashamed!" ”

Cao Nai's mind turned for a moment and asked, "Xu Shiyu, are you interested in coming to the Ministry of Officials to develop?" ”

"Huh?"

Xu Pu was stunned, what did he say?

Cao Nai smiled and said: "The emperor issued a decree to reorganize and reorganize the ministries, one of the most important of which is to add various research institutes, the old man has always thought that the ministry does not need the support of the Academy of Sciences, and today I understand that the old man is shallow!" ”

Zhang Yi immediately reacted and hurriedly said: "In fact, the Ministry of Rites also needs a talent like Xu Shiyu. ”

Seeing that the two of them began to recruit, Yang Shan stopped holding it up, and said with a smile: "The position of Shaoqing of Honglu Temple is still vacant, Xu Shiyu think about it?" ”
