"No business, no wealth, no agriculture, no stability." The old man muttered this sentence, and did not bother with the status of agriculture as a compulsory course.

However, many scholars, especially the children of the big families, do not know anything about agriculture, and even look down on the peasants from the bottom of their hearts, thinking that they are pigs and dogs. Therefore, I opened the agronomy not only to let the scholars learn agronomy and understand agronomy, but more importantly, to let them know the importance of the peasants to the country, let them respect the peasants, understand the peasants, and face the peasants squarely, hoping that tragedies like the Yellow Turban Rebellion will not occur again in the future. ”

Lu Chen took a bite of the mutton bun and added: "If there are no farmers, where can I eat steamed buns?" Learn from the barbarians to drink blood. ”

Pang Degong sighed slightly, obviously, Lu Chen's opinion on the Yellow Turban Thief made him suddenly realize that he was enlightened, and he realized that not only himself, but even the Confucians he knew had never considered this aspect. They only regarded the Yellow Turban Thieves as a flood of beasts, but they never imagined that they would rise up only because of one very small desire - to eat.

"When we talk about agriculture, let's talk about law." Lu Chen continued to talk eloquently, "Every family has family rules and national laws, there are no rules, there are no rules, heaven and earth have their laws, and the four seasons have their laws, so the people can survive in spring and autumn." The country naturally has its own laws and regulations, let's take a look at the difference between the barbarians and our Han people, where the strong are respected, and the weak eat the strong. If you are weak, you will become someone else's slave or even food. If you are strong, you can enslave thousands of people. I'm not afraid of old gentlemen's jokes, when I was fighting a few months ago, I inexplicably robbed a Hun woman. It's a Xiongnu princess dressed as a man, her name is Wuzhu, you must have heard of it. I didn't restrict her freedom, but she didn't leave me, but took it for granted that she would be my woman, even. Recently, cattle, sheep and horses have also been raised. You know why? Because she thinks I'm poor, and I'm poor is a note that she's not industrious enough, so. She was desperately raising cows, sheep and horses, and she cried all night when she heard that two little lambs had drowned the other day. Then the lamb was roasted and eaten. In her opinion. Gold, silver, money and silk are not wealth, the real wealth is cattle, sheep, horses and herdsmen, more cattle and sheep, you can provide enough food, enough food can raise enough herdsmen, and herdsmen with war horses, is strength! In the steppe, there is a struggle for pastures and cattle and sheep, and population. By war.

"In a sense, the current Han world is similar. Whoever has the biggest fist will listen to whomever he is. However, the gentleman must know that this was not the case with the Han Dynasty a few decades ago, at least not on the surface, because in peacetime, the state has laws to bind its people, and the cultivators have their land, so there will be no turmoil, and the laws of the country guarantee their right to farm, and they will not be plundered by others, so that they can live with peace of mind for generations. There are corresponding punishments for small things like fraud, robbery, and theft, and for big things like murder, rebellion, and collaborating with the enemy. Therefore, people have a scale in their hearts, although it is said that crime cannot be eradicated, but the law is a deterrent, but also a shackle, which greatly increases the cost of crime, eh, can you understand? It can reduce the occurrence of crime.

"There is a saying that the troubled times use heavy canons, and this is the case, and in troubled times, the law is usually morally degraded, and the law is useless, and then the benefits of the law can be more reflected." Lu Chen came to a conclusion, "The morality of a saint can only restrain people with morality, but there are more people in the world who don't learn, and everyone has greed, who can restrain it?" Only the law! Therefore, morality, while important, is the basis of the structure of the law, but it can never replace the law. Think about it, if a person commits adultery and plunder, how are you going to punish him morally? Draw a circle and curse him? So, if an official doesn't even understand the law, how can he rule his people? ”

"Troubled times with heavy codes? Law can be set as a compulsory subject, but what about Gewu? In my opinion, although it is quite subtle, it has little to do with the safety of the world. Pang Degong asked again.

"Knowledge." Lu Chen smiled slightly, this is the simplest, "Zi said: Knowing is knowing, not knowing is not knowing, and knowing is knowing." He also said: If you are a threesome, you must have my teacher. However, I think that the first sentence of the saint is very correct, and the second sentence is also very reasonable, but the second sentence is not comprehensive. Because there are many things that people don't know at all, whether you and I or the saints, we don't understand, who do we ask? ”

"Daxian can know five hundred years before and five hundred years later, how can there be no one who doesn't know?" Pound is fair.

"Does the old gentleman know about the next five hundred years? Not to mention 500 years, do you know where the world's strife will go in a year's time? You don't know, and neither do I. Lu Chen thought to himself, I knew it originally, but history seems to have deviated a little because of his arrival, Lu Bu is not dead, Gongsun Chan is not dead, Zhang Yang is not dead, there are too many changes.

"That's just because, neither you nor I are great sages."

"However, there are some things that Daxian doesn't know."

"What?"

"Man can speak, birds can cry, beasts can call, insects can sing. But, what is the speed of the sound? Do you know, sir? Can the great sages know? ”

"Of course it's the fastest, as soon as I open my mouth, you can hear it, and at the fastest, who can understand its speed?"

"It's not. Have you ever watched a thunderstorm at night? Lightning flashes in front and thunder in the back, why? Could it be lightning and then thunder? No, because the light is faster than the sound. Perhaps the old gentleman does not agree that lightning and thunder occur at the same time, then I can prove it with another fact. Sir, have you seen my gunpowder bomb in Yanmen? ”

"I've seen it, naturally."

"Then Sir should know that the explosion and fire came out at the same time as the sound, right?"

"Yes."

"But if you put a bomb a few miles away and explode, you'll see the light of the fire first, and you won't hear it until a few breaths later."

"This??"

"Do you remember what I told you last night, old gentleman? This also proves that the speed of sound is not the fastest. And how fast the sound is, I don't know, what to do? It's only a matter of knowing things. Only through research and practice can we understand the world better, and only by understanding the world can we make better use of it. ”

"You haven't said yet, why can Gewu be included in the compulsory subjects?"

"Sir, remember the pulleys I used to build the walls, right? You also know cement, coal, oil and gunpowder, right? These are things that I know from the object, and I have transformed him into a tool that we can grasp and use, and that is progress. This has been the case with many inventions throughout the ages, and strictly speaking, pharmacology is also a kind of lattice that studies the effects of animals and plants on man. So, more and stronger knowledge helps us to invent stronger and more advanced tools. These tools may be used in the military, in architecture, in agriculture, in medicine, and even in Confucianism, such as pen and ink. I think that Gewu is related to the future of civilization, and it is important to decide, sir? (To be continued......)
