The second brother smiled, "Actually, what several adults lack most now is nothing more than two things, time and money." Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoIf you can find a way to make these two things no longer lacking, in fact, most of the problem will be solved, I don't know what the kid said, how many adults understand? ”

The little second brother's best skills are starting to work again.

Xiao Yu nodded, slowly pondering this sentence. Maybe in the future generations where knowledge is exploding and information is everywhere, such a simple thing still needs to be understood? Any person can say a lot of words when he opens his mouth.

But this era is different, everyone's thinking has not risen to that height, and the concepts of time and space do not have a relatively clear definition at all, so don't look at these four are the most capable people in Datang, they are still inferior to the child Xiao Er.

"You go on, and we listen." Du Ruhui felt that it was better to listen to Xiao Er before thinking about it.

"Good!" Xiao Er smiled and continued: "In fact, there are such things as big droughts not only now, there are many in ancient times, and there will be in the future, we can't wait until the drought comes every time to find a way, if we can slowly grasp the characteristics of the law of drought, then we will be relatively simple to deal with." ”

Seeing that the four of them listened carefully to themselves, the little second brother was very satisfied, "Let's just talk about drought, in fact, it's nothing more than a lack of water, as long as we can solve the water problem, nothing else is a problem." ”

The eldest grandson Wuji was actually very interested in what Xiao Er was going to say, so he listened very carefully, how did he know that Comrade Li Xiaoer said such a sentence, and he almost didn't make the eldest grandson angry, use you to say! Who doesn't know that drought is a lack of water! If you can solve the water problem, you still need to ask this yellow-mouthed child?

All four of them are high-ranking officials, but in the performance of a thing, age determines the person's behavior and cultivation.

The eldest grandson Wuji was already ready to wave his sleeves away, Du Ruhui frowned slightly, Fang Xuanling was expressionless, only Xiao Yu's eyes lit up, and then nodded and smiled.

Everyone's expressions fell on Xiao Er's eyes, and he couldn't help but sigh, even geniuses need time to temper, and without a certain amount of years of accumulation, they can't become masters.

He looked at Xiao Yu and said, "It seems that Xiao Shangshu has already understood what the kid is going to do?" ”

"Do you really have a way to do it?" Xiao Yu pressed her excited heart and asked in a calm tone.

"Yes, but there are too many people and things that need to be mobilized, and the kid is young and doesn't have that ability." Although the second brother is sometimes very arrogant, he is quite sober in this kind of big thing, knows where his level is, and will never be ashamed.

"As long as you have a way, the old man will fight with His Majesty for everything you need." Xiao Yu can conclude from Xiao Er's tone and demeanor that this little guy is actually confident.

The two of them said a few words, and the other three didn't understand at first why it suddenly seemed that the problem had been solved, and then they realized one by one.

"Little Er, do you want to fundamentally solve the problem of land water shortage?" Fang Xuanling was also surprised when he figured it out, Li Xiaoer's idea was too bold and too radical.

"Yes, the kid is thinking, this drought, maybe the adults can find out in advance and think of a way to solve it, so what about next time, and then later? Will there be people like you who will find the problem and be enthusiastic about solving it? Li Xiaoer's attitude of worrying about the country and the people has added a lot of positive points to himself.

"So the kid wants to solve the problem fundamentally, which is to find water. Drought is a lack of water, and as long as we have enough water to irrigate the land, the drought will not come again. ”

"It's easy to say, how many capable people in the past dynasties are looking for a way, you can solve it with your mouth open?" The eldest grandson Wuji sneered.

"What do you say?" Du Ruhui then asked, he didn't want the eldest grandson to interrupt Xiao Er's train of thought.

"It's easy, dig a well!" Li Xiaoer was very awesome and put on a piece of cake, and said two words.

At this time, not only the eldest grandson Wuji chuckled, but even Xiao Yu couldn't help frowning, I don't know how many times this method has been used since ancient times, and I don't see that there is no shortage of water now, it seems that the young man is a young man in the end, and he can't do things with hair on his mouth!

Even Fang Xuanling hesitated for a moment and said, "Xiao Er, the method you said is simple, but this can't solve the current problem at all, let alone once and for all." Saying that, Fang Xuanling looked at Du Ruhui and said, "Keming, you should come and talk to him about the problem of private wells now." ”

Du Ruhui nodded: "Xiao Er, digging wells has been going on since ancient times, and it is not a new thing." But you must know that well water is not something that can be made casually. Like the land of Guanzhong, the eastern plain is basically ten wells and five waters, and then to the west, ten wells and three waters, if you go to the westernmost side, it is probably fifteen wells and one water. ”

Saying that, Du Ruhui obviously showed a worried look, "This is still on the Guanzhong Plain, and many places in the Tang Dynasty cannot drill wells at all, and it is estimated that you can't even withstand this drought with this method." ”

Greater China is a vast country with diverse terrains, which has created a situation where many colleagues have different reasons and different laws. Let's just talk about digging wells to get water, and the whole Guanzhong should be treated differently.

In the eastern plains, ten wells are drilled, five can see water, three out of ten can see water to the west, and if you go to the mountains in the west, fifteen can produce a well, so what several adults said is the truth, and it is no wonder that they feel unreliable after listening to Xiao Er's words.

Xiao Er is not stupid, of course he knows this situation, he said with a smile: "What you adults said is reasonable, but the situation of digging a well and not producing water actually does not mean that there is no water in that place, but that there is no good way to find it at all." As he spoke, he stepped to Hu's table.

said with a smile: "Xiao Shangshu, the kid is going to use pen and ink." Without waiting for Xiao Yu to speak, Xiao Er spread out a blank piece of paper, picked up the brush and began to write and draw.

Originally, a few people had stopped reporting hope, and when they heard that Xiao Er was going to write something, several people decided to continue to listen to it. But seeing the little second brother clumsily holding a brush where to write, his heart sank again, this kid probably hasn't even read a book, is this using a brush?

The little second brother didn't care about this, he was engrossed in writing, and sometimes he had to tilt his head to look at it, and the few people who watched it shook their heads again and again, and their hearts were even more dead.

Finally, Comrade Li Xiaoer finished writing and painting, so he breathed a sigh of relief, looked up at the tangled expressions of several people, and smiled embarrassedly: "The kid doesn't know how to use a brush, forgive me!" Hey! ”

He didn't care what others thought, put the paper on the desk and said, "Four adults, please take a look." ”

The four of them didn't know why they were so obedient, so they went to the case very obediently, looked down, and found that Li Xiaoer was not writing at all, but drawing.

On a large piece of paper, a few thick lines, and a piece of black balls smeared with ink, it was very uncomfortable to look at. The eldest grandson Wuji is a little pitiful of that piece of paper now, what a good piece of paper, it was wasted in vain.

"Look here, this is the plain on the eastern border of Kansai, yes, this line." The little second brother pointed to a thick line on the right hand side and explained.

The four of them turned their heads, and they couldn't see that the line had anything to do with the Guanzhong Plain.

Looking at the expressions of several people, Xiao Er was depressed. He drew a three-dimensional profile, but he didn't know how to profile. The little second brother was a little helpless to hold his forehead with one hand, so he had to explain the meaning of the section first, and then he saw that everyone was a little enlightened, and then continued.

"This is the ground, this is the underground. The reason why it is easy to dig wells in the plain area and see more water is because this aquifer is relatively close to the ground, and the land in the plain is relatively soft, so as long as the aqueous layer is hit, water will generally come out. ”

Xiao Er said and pointed to the middle of the paper and said: "This is the place to the west, the terrain here is gradually rising, and there is a water layer but not rising, so the distance from the ground is farther than the plain area, and most of these places are not easy to drill wells, some hard soil and gravel, so it is more difficult." ”

He pointed to the black ink blocks on the far left and said: "This is a mountainous area, and the water layer has basically not changed, but the ground is either a high mountain or a rock, and it is impossible to drill a well, which is the reason why there is one water in fifteen wells." ”

After saying this, he looked at the four people: "What the kid said about digging wells and getting water does not mean that there is no difference between drilling wells in various places, but adapting measures to local conditions, drilling wells that are suitable for drilling wells, and those who are not suitable for drilling wells can use other methods to transport water over, this is a problem of methods, and it is not impossible to solve." ”

After Xiao Er finished speaking, he stopped talking and watched the reaction of the four people.

Xiao Yu didn't get close to the front at first, he just stood behind and listened to Xiao Er, when Xiao Er introduced the situation, he was a little nervous, these things were really a bit unbelievable according to his understanding.

How can Li Xiaoer understand that there is a layer of water underground, this is unreasonable. Everyone knows that the well water comes from the ground, but no one knows why there is water underground, where it comes from, and how it goes underground.

But now Li Xiaoer has made this problem clear in a conclusive way, and he has also said in a very orderly manner why he can't drill wells and why there is no water when he drills wells, which is the first time in his life that he has heard such an explanation so clearly.

The old man didn't care about his image, he just lay on the desk, stared at the paper with his eyes on it, and looked at it little by little. However, Fang Xuanling was a little calmer than him, and after listening to Xiao Er, he thought for a while and said: "Then Xiao Er, how do you say that the water in the mountains is transported, the roads are difficult to travel, and the cars and horses sometimes can't get in, how can the water arrive?" ”

Xiao Er really wanted to laugh after listening to Fang Xuanling's words, people in this era are so simple-minded, why do you have to send the water after it comes out, can't you let the water be sent over when it doesn't come out? It seems that it is time for me to popularize the methodology to them!
