How could Dayu not know the role of knowledge? People who have learned knowledge and those ignorant people at the bottom are two different worlds.
Even if he knows a little bit about arithmetic, his future will be much brighter.
The power of knowledge can change a person, and if all human beings learned knowledge, how terrible it would be.
Of course, Dayu also knew that this was impossible. There were tens of billions of human beings, and it was impossible for everyone to be literate, let alone learn more profound knowledge of articles.
However, with the printing technology and paper, the spread of knowledge will definitely be more convenient, and there will definitely be more people learning knowledge in the future.
If in the past, there was only one person in a thousand who could read and write, then in the future there may be ten or even more.
This is a good thing. It is a good thing for the human race. The more knowledge is spread, the stronger the human race will be.
"very good!"
Dayu couldn't help but said that the person who invented these two technologies could be a great sage of the human race.
Of course, when Dayu saw the contents in the book, his face was even more happy.
"This is the treasure book"
Dayu's soul stirred, and there was an instant movement of the seasons. This is where the luck of the Fire Cloud Cave rolls.
"What?"
When everyone heard Dayu's words, they were stunned. They all looked at the book in Li Si's hand in a daze. Even Li Si was a little stunned.
Naturally, he had read the contents of this book when it was delivered to his disciples.
The content mainly talks about the prevention and treatment of some simple diseases and the effects of some herbal medicines.
The content is very plain, but if you are not a fool, you will be able to understand it if you read it several times, and you can even copy it. If you are really sick, you can generally cure yourself by following the above content.
For this reason, he had previously sent his disciples to try it out, and the contents of this book were found to be at least 80% acceptable.
Because the content of this book is very simple and clear, anyone who can read can understand it, and Li Si also understood the thoughts of the person who wrote this medical book.
The news brought by the disciples was that this book came from the countryside of Qilu. In many villages, as long as there are some literate people, everyone has a copy. There are even more Confucians who go to the countryside to teach the lower class people.
Li Si admitted that the role of this medical manual is absolutely a supreme treasure for the millions of people at the bottom of the Qin Dynasty, because with this medical skill, the people at the bottom will have the ability to save themselves as long as they learn it.
For minor illnesses, there is no need to hold on.
Li Si came from the bottom, so he naturally knew that the people at the bottom looked down upon illness at all. Once they got sick, even the simplest illness would be a life-threatening talisman for them.
And with this medical skill, most people can survive.
Of course, it is still difficult to survive a serious illness, but it is enough.
But what makes Li Si suspicious is that this medical book alone can make a person become a human semi-saint. Is it unlikely?
It's not that Li Si doubted Dayu and others, but Li Si always felt something was wrong about this matter.
"wrong!"
Dayu immediately said, "The contents of this book should not be complete."
When Dayu said that was wrong, Li Si was shocked when he heard the words, and a smile appeared on his face. However, the next second, Li Si was also stunned.
"The book is incomplete?"
"There should be some more"
Dayu immediately used this book to deduce. Although the heavenly secrets were chaotic, he was in Kyushu and had physical objects, so it was much easier to deduce.
“Sure enough, there’s still half of it.”
During the deduction of Dayu's soul, he also saw the other half, but he could not see the content of the other half.
"You said this book was brought here from the land of Qilu?"
Dayu looked at Li Si.
Hearing this, the latter nodded repeatedly.
"very good!"
Immediately after Dayu finished speaking, his entire figure disappeared.
Everyone was stunned when they saw this.
"This is Prime Minister Lu.
.
"
Everyone was relatively speechless.
"It's enough for everyone to know about this matter, and don't spread it around."
Lu Buwei thought of something and immediately warned.
To be able to make Emperor Yu descend to earth in person, it is obvious that that person is not simple. He is a future half-saint of the human race, that is to say, his current level is not very high.
Huoyundong was definitely worried that he would be discovered by Heaven, so he took the first step to protect this person.
In this case, there is no need for them to go into details. With Emperor Yu's protection, they, the Qin Dynasty, don't need to bother.
On the other side, Dayu left Xianyang City, and in a few flashes, he arrived at the land of Qilu, swept away by his spiritual consciousness.
In an instant, I saw the book Li Si mentioned in many countrysides.
Sure enough, as he said, there are such books in the homes of some elders or pavilion chiefs in the countryside, or in government offices.
Even some literate people gathered in the countryside to explain the contents of the book to the lower class people in the countryside.
And these common people listened very carefully and did not dare to miss anything.
Seeing this situation, Dayu was very happy.
He could naturally see the contents of that book clearly. Compared with those medical books compiled by doctors, the contents were much simpler.
Moreover, self-help and treatment are all for minor ailments, and there are no symptoms of intractable diseases.
But it is these small problems, the most common cold syndrome, that can often kill countless people at the bottom.
Once the people get cold, most of them don't have money to hire a doctor, so they all fight hard. If they can survive, they will die. If they can't, they will die.
With this medical book, it will be different.
In the future, these people at the bottom will be able to survive, whether they are children, the elderly, women, etc.
If you survive, you can pass it on to the next generation, and the population will accumulate more and more.
Especially regarding young children.
Dayu knew very well that whether in ancient times or today, the survival rate of young children has never been high. Nowadays, those nobles in power are lucky because they have doctors and can always take care of them.
But for the people at the bottom, it all depends on luck.
In this book, there are teachings on how to raise children, which can maximize the survival rate of children.
In Dayu's opinion, this is the most important thing.
The more young children survive, the more the population grows.
Many lower-class families often have six or seven children in their families, but only one or two actually grow up.
Not only because of the food, but actually more importantly, the children are too weak. Once they encounter any accident, there is almost no possibility of survival.
Adults still have a chance to survive when exposed to wind and cold.
Once a child encounters a cold, unless he is cared for by a doctor, he still has a chance to survive. However, the people at the bottom of the family, who have this condition, naturally do not have it.
Dayu knew very well that it was very difficult to survive in the countryside, let alone have enough money to find a doctor.
Even in many rural areas, there are no doctors, only in the county government. However, it is so far away from the county government and the countryside that many people cannot get there even if they have money.
