"Sun Zhenren, why can't I understand? Isn't that what you're talking about? Liu Qingcian continued to ask with some curiosity.

Li Ke didn't interrupt Sun Simiao's words, he just smiled.

"These are two concepts, I say that His Highness is knowledgeable, which means that His Highness knows a wide range of knowledge, covering almost all aspects of life, and even including many doctrines are involved, but His Highness is not deep in these aspects, but some of his theories are correct, take medicine as an example, His Highness is not as deep as I have learned in the specific treatment of medicine, but some of His Highness's concepts are more advanced than me."

"And these ideas are not just from the medical aspect, but His Highness knows many aspects of knowledge, corroborates each other and then comes to the conclusion that everything in the world is naturally intrinsically connected."

"But this situation ...... In fact, it is very strange that this breadth of knowledge, to be honest, theoretically difficult to appear in such a young person as His Highness, unless His Highness is born to know, otherwise he must be at least sixty or seventy years old, have read the speeches of a hundred schools, and have to travel thousands of miles to have such extensive knowledge. ”

"But none of these Highnesses have any." Sun Simiao glanced at Li Ke when he said this, Li Ke didn't care, but he was also emotional, otherwise people would say that people are old and fine.

Although Sun Simiao didn't know Li Ke's origin and identity, Sun Simiao guessed the answer that was extremely close to the truth through his insight.

As Sun Simiao said, the knowledge that an ordinary twenty-year-old young man in later generations came into contact with, maybe he didn't think anything of it, but put it in the Tang Dynasty...... Even a person like Sun Simiao, who has spent his whole life walking in the Tang Dynasty, is difficult to receive such a wide range of knowledge.

This is the concept of scientific and technological progress, which is why the post-80s and post-90s generations think that those post-20s children are so smart.

In fact, the principle is the same, children born in the 20s receive more information than children born in the 80s!

The human brain is amazing, these things that we don't usually pay attention to, in fact, your brain has received a lot of knowledge for you.

A modern twenty-year-old college student, even if he is not good at politics or anything like that, if he is thrown to Datang, and he happens to be a county official, as long as he is not playing black tricks for him, everyone will support him and let him operate normally, this college student will definitely manage a county better than more than 90% of the county officials in Datang! Even a little bold, ninety-nine percent.

This is the reception of information by modern people, which may seem useless in modern times, but in fact they also play a huge role in daily life.

For example, Li Ke was a relatively good social animal in his later life, and he knew that those self-proclaimed civilized aristocratic lords in the West often played a kind of unimaginable for ordinary people: silver plate service.

If you want to put it in ancient times, which ordinary person can know this?

"That's not smart, it shows that His Highness is smarter and can see more things than everyone else." Liu Qingcian said proudly.

"Haha, that's right." Sun Simiao laughed twice.

"By the way, Sun Zhenren, I have something to trouble you." Li Ke remembered one thing, which was submitted by Tian Meng yesterday.

"What's the matter?"

"That's right, the Ministry of Construction needs you to send a few experienced doctors to follow them to carry out the construction work." Li Ke said.

"That's fine, but what are the main aspects?" Sun Simiao asked.

"Common diseases such as headaches, brain fever, wind and cold, and then trauma, there may be some more serious injuries, such as the need for amputation, at least there must be a certain emergency treatment ability." Li Ke said seriously.

"In this case, it takes a strong doctor, and it also needs to be trained by us." Sun Simiao thought about it seriously, being able to deal with this kind of major trauma is not something that ordinary doctors can handle, and it still needs to go through their special training.

"But what is this going to build? Is it possible to have such a serious trauma? Sun Simiao looked at Li Ke with some curiosity.

"Build roads and bridges." Li Ke smiled.

"No wonder." Sun Simiao didn't understand this, but Sun Simiao had seen the manpower used when building roads near Chang'an.

"In the short term, their work location will be near Chang'an, but this road will be built all the way to Chencang (Houbaoji), and eventually even to Jincheng, Chihai City on Qinghai Road, etc. They are estimated to have to follow all the time, of course, rest assured about the welfare benefits, they are all subordinate to the Ministry of Construction of Datang and eat the country's imperial grain. Li Ke said with a smile.

"Yes, I'll make this clear to them then." Sun Simiao nodded, the profession of doctors has not been particularly poor since ancient times, so if there is anyone willing to follow the construction team, Sun Simiao is not very clear, he has to talk to the other party.

"However, are you going to repair the official road that has been going to Qinghai Road?" Sun Simiao asked with some curiosity, "Directly use the concrete road to repair it?" ”

"Yes and no." Li Ke shook his head.

Naturally, this road cannot be built as a pipeline, but as a railway! To be precise, the first phase of the experimental railway was built from Chang'an to Chencang along the Wei River.

In fact, many national highways, county roads, and provincial roads in later generations have been handed down by ancient pipelines, especially the national and provincial highways that pass through the mountains, and almost all of them are ancient official roads, not counting the parts of tunnels.

When the official roads of the Tang Dynasty pass through the mountains, they also follow the edges of the rivers and valleys in the mountains.

"Something new?" Sun Simiao looked at Li Ke with some curiosity.

"Of course, if it is built by then, it may be possible to carry tens of thousands of tons of goods to travel thousands of miles a day at one time." Li Ke said with a smile.

Sun Simiao was stunned for a moment, he had been mixed with Li Ke for so long, he naturally had the concept of tons, after all, many of the medicinal materials they received now were calculated according to tons, tens of thousands of tons a day, thousands of miles a day?! If that's the case...... Then the Western Regions is not called far away from the Tang Dynasty at all.

"Then you have to repair faster, the old man is ninety-six this year, and I still want to live to see this day." Sun Simiao was very emotional, although he was old, he was also very interested in new things.

"Rest assured, your old man is in good health, and he will definitely be able to see it." Li Ke's expression was somewhat strange.

It's true that you are ninety-six, but if you count according to the age in history, there are a lot of newly-born babies in Datang this year who will not survive you.
