"If my father thinks that these 50,000 Huns are not enough, his sons can also go and let them arrest people again. Erchen believes that there should be more than a million people on the prairie. The Xiongnu alone were not really able to manage all the tribes in the steppe. Even if it is a big man, there are many savages who do not pay taxes. ”

Qian Rujun said to the emperor seriously.

Even after coming to Dahan for so many years, Qian Rujun has a broad understanding and has no good impression of politicians.

What they do is actually to bring more benefits to their own families when they complete the "big things" of the country.

"Father, you have to believe your sons, there are not only cattle, horses and sheep on the prairie, but also many minerals that are very helpful to us. Coal mines can reduce our logging, and reducing logging can reduce the loss of water and soil, and if the Guanzhong Basin continues to be cut down like this now, this place will cause soil erosion in the future. ”

"You're talking about the kind of thing that emits black smoke? It does burn longer than wood, but it just emits black smoke and the air doesn't get very good. What is soil erosion, can you elaborate on that?"

Emperor Liu Heng felt that Qian Rujun would pay attention to some terms that he seemed to understand, but he was not familiar with them.

To put it simply, this term is too vernacular, and it doesn't seem like what an elegant person should say.

Emperor Liu Heng was actually the biggest literati of this era, although he had no literary talent himself.

Qian Rujun has never liked people who don't understand anything.

Moreover, what the other party doesn't understand is nothing else, but the courses that are usually taught in middle schools, which will make Qian Rujun feel very contemptible.

However, in Dahan, the other party doesn't understand this kind of thing, and Qian Rujun thinks that this is really ridiculous.

The emperor does not understand these basic truths?

How silly would that be?

This is a post-mortem elementary school student who can understand disasters related to daily life.

Qian Rujun can only understand that in this era, there are many nouns that she doesn't understand, and the same simple truth is explained in later generations.

The emperor didn't know, not that he really didn't understand, but that she knew too little about the proper nouns of this period.

"Soil erosion is a phenomenon in which water carries away the soil when it rains, or where there is water.

Originally, this is a real phenomenon, a place, also has the power to generate soil on its own, but at a very slow pace.

If the rate of churn does not exceed the rate of generation, it will have no effect.

However, if this speed is exceeded, and by a lot, it will be a disaster for one place.

In extreme cases, we can see this kind of catastrophe right away.

The grassland is probably the most vulnerable area, because all the grass is covered with soil, and only a thin layer of vegetation is protected.

At this time, there is no need for rain, and the wind alone can lift the dust and carry it to other places.

This is how the Loess Plateau came about.

If the soil is bare, all the soil will be carried away by water and wind, and even all the nutrients will be taken away, and there will be no way to cultivate it anymore. ”

"You mean that our act of cutting down trees and building houses is harmful to the earth?"

The emperor said thoughtfully, for the emperor, agricultural production is very important, which is the foundation of the feudal dynasty.

Without food, the Han will have no money and food.

Rich people, in fact, did not contribute anything to the Han court.

"This soil is very important for us to produce new crops. ”

Qian Rujun knows this truth. So she used this to tell the emperor.

"And it's better not to plant the same crop all the time in a place, but to change it in turns, so that we can restore the fertility of the soil, because the nutrients that each crop can provide and absorb are fixed, and there will be no sudden increase or sudden decrease. If there's no way to grow something different, then fertilize!

The sons had already taught the palace how to grow plants, but why had they not seen the people do it after so many years? At most, they burned some wood and weeds to fertilize the land. Don't get dirty!"

"Why haven't I heard what you're talking about before? Doesn't it affect our farming in the Guanzhong Basin? This is a big problem. In the future, we have to let them cut down trees less. It seems that the concrete building you brought is the solution to the problem, right?"

"If it continues, there will definitely be soil erosion, and there are already some signs. The grassland is also the yellow sand that the northeast monsoon carries every year, driving the surface soil to the south, the south is fertile soil, but it will also pollute the air, and the north will lose the soil, and there will be no grass.

The grasslands will be even more miserable, and once the plants do not grow, large areas of yellow sand will move south, which will harm the crops in the fields.

Don't think that Erchen is alarmist.

The river will also lose its original clarity and become yellow, and the yellow and turbid water will cause the river to silt up, although it will create new land.

But it will also cause flooding, and the Yellow River, a river, flows northeast when it reaches the plains.

In this direction, there will be a big problem when the winter passes, that is, the ice in the north has not yet melted, and when it melts, the ice in the south has already dissolved.

The problem of this situation on the plateau is relatively small, and most of the submerged land is not too large, but if it is in the plain area, the problem of the Yellow River coming out of the water may be the problem of tens of thousands of acres of land, which is not a trivial matter. ”

Qian Rujun worked hard to dig out the previous common sense in his head, hoping to make the emperor understand the knowledge of their leaders at that time.

At that time, she was just a small civilian household, and these things that flooded and caused disasters had nothing to do with her.

As long as you find a way to escape when you are in trouble, you will be fine.

Fortunately, the traffic is very convenient, the south floods to the north, the north floods, and to the south, basically there will be no problems.

The most feared thing is the influx of seawater, and in the end, when the ice in the Arctic melts, the ice in the Antarctic, and finally the sea rises and there is no way to live in it, they will have nowhere to go.

Qian Rujun said that the emperor listened very carefully, whether Qian Rujun was talking nonsense or not, these terms were very precious in the eyes of the emperor.

He believes that this is the knowledge of the gods.

It was rare for Qian Rujun to be in the mood to speak, so he listened hard and tried to remember.

He didn't even ask the eunuch to help him memorize it together.

It is estimated that he thinks that these are the knowledge of the emperor, and outsiders cannot learn it.

In fact, when he reported the disaster in various places, he mentioned these things more or less, but the reasons for their explanations were mostly not based on scientific evidence, but the punishment of God, and he did not think of a solution.

It cannot be said that there is no solution, and their solution is to worship God. but they turned a blind eye to the ways in which the heavens hinted at them.

"In the past, it may have been my father's mistake to divide you to Jinmai and let you develop there. ”

Emperor Liu Heng suddenly had a feeling. made Qian Rujun's hairs stand on end suddenly.

Whenever the emperor started saying something she didn't understand, she knew something was going bad.

"Huh?

Qian Rujun didn't think there was anything wrong with this, on the contrary, she was doing well outside, free and happy.

She felt that she was the emperor's old man, and she was going to pit her again, and she didn't know what the emperor thought of again.

"I feel from your words that you are actually very experienced and rich in water and soil control, and even you have a way to solve the problems of drought and floods and floods!"

The Emperor said slowly.

There are many problems in this area of Dahan, and someone needs to solve them, but unfortunately, there are too few experts in this area of Dahan.

Even if there is, I know that there is no money Rujun said.

"That place in Golden Wheat City is not suitable for living, but you can develop it into a city where you can live in the New Deal, and the transportation is very convenient. Where has it become very rich now, and even better than Chang'an in a certain part.

Before, this fast land was a swamp, a land that was originally water, and you turned it into a place where you could fish by boat.

Your talent and wisdom are far more than what I have seen, there are still many things you can do that you have not done, and things in the Guanzhong Basin will not happen for the time being, because there are still many trees in the Guanzhong Basin, and there are still many places that have not been developed.

What you said, I will order it to go down, so that the magistrates below can pay more attention, no more indiscriminate reclamation, and when it is developed, it will also keep the appropriate land and keep it green, but the land near South Vietnam, there are almost no people, can be developed and cultivated, maybe you can go to that place and try it. ”

Qian Rujun felt that the emperor was talking nonsense now.

"Father, do you want me to go there to be a magistrate? I'm a relative of the emperor, right?"

Her fiefdom was in Jinmai, and it was not suitable to go to the south.

"When you are old, you should actually give you a husband, and you will be assigned to be an official over there, but for the time being, your husband cannot be a marquis now, and the marquis is not suitable to be a magistrate.

For your husband, I don't ask him for any status, or anything else, he can even be a beggar.

As long as you like him, you can marry him, and then I will make him an official and send him to the south, so that he can develop the south, so that he can build up merit and obtain enough capital to marry you, otherwise, you will look down on him.

You also said that in fact, farming in the south is more advantageous than in the north, and if the diseases in that place can be removed, more people can survive, then the crops produced and cultivated in that place will meet the needs of all our Han people, for this purpose, you will find a husband, and I will wait to seal him as an official!"

The more Emperor Liu Heng said it, the more excited he became. But the black line on Qian Rujun's brain became thick and big.

"Father, you can't be cheated like this, your sons don't want to marry, and your sons' age hasn't reached yet?"

"If you don't want to get married, then you can find a woman, and I can accept a woman, as long as she looks like a man.

It's just that in the future, you won't be able to have children, there will be no offspring, and everything you have created will be accepted by me. You won't be reconciled, will you?

But it's not a big deal, which princess of this dynasty is not a child with a husband other than her,

Liu has done a good job in this regard. ”

Damn, it turns out that the emperor knows what his daughter is like.

Having said that, when a Han woman develops an extramarital affair, she really doesn't have the idea of hiding it, and even announces the matter to the public, and the man who is cuckolded feels nothing.

Maybe these princesses have basically never seen a good man who relies on themselves.

can let the princess get a little benefit, they don't follow along.

Those who want to be princess mistresses have more or less something excellent. The gift for the princess will not be bad.

The big man, the man, and the woman, all have a common idea.

It is more important to get benefits, life is too difficult in this era, if you want to live a better life, you must grasp every opportunity, let women go outside to find men, and it is also a way for men to develop opportunities.

Even some wealthy families will especially accept concubines from aristocratic families and marry them as their wives, I heard that this can save education expenses.

The emperor, for Qian Rujun, is usually a very good talker, and the emperor rarely does not listen to what she says.

But for such a thing as marriage, Emperor Liu Heng seems to be very stubborn, and insists that Qian Rujun send out the candidate list as soon as possible.

Qian Rujun is going crazy.

originally thought that the crisis of marriage would not begin until she was fifteen years old, but she did not expect that the emperor would want to marry her off so early.

is also very kind, I found that Qian Rujun was very dissatisfied with the officials of the imperial court, as well as their children and noble officials, as well as their children, so he was very gracious and let her choose at will, as long as he chose one, he would be given an official and let him go out and govern the land in the south.

Of course, marrying her still has to be accomplished.

So Qian Rujun can choose more than one candidate.

Although there are many feudal states in the south, the prefectures, counties and counties are actually still there, and even Hainan Island was governed during the Han Dynasty, and no one prevented the Han Dynasty from setting up officials to govern. It's just that the emperor didn't think it was necessary.

In other words, in fact, if Qian Rujun can go to the south, he can cut down trees for the reason of cultivating his husband.

The trees were cut down to make up fertile fields, and a lot of food could be grown in three seasons a year.

In fact, Qian Rujun believes that the people of the Han Dynasty are not short of land.

Even if the wasteland is developed, it can survive.

The most important thing is that no matter how much they cultivate, there is not enough food, not because of the lack of land, but because of the cultivation technology.

Even if Qian Rujun planted more grain and could sell it, for these people who could not grow enough food, they could not afford to buy it, they could not afford it, and they could only accept relief from the imperial court, or starve to death.

But to save the emergency, not to help the poor, the imperial court also has this attitude.

It is better to teach others how to set up nets to catch fish and be a good fisherman.
