"Uh.... I'll talk about this reservoir later. ”

"Third, prevention. As the world says, floods are natural disasters, and the amount of rain that rains every day of the year is immeasurable, so we can only measure the water level of the river on the spot through special errand officers in various places, and once the warning line is reached, emergency measures are immediately organized. ”

"And this emergency solution is the reservoir that my grandson just mentioned."

To put it simply, Grandpa Huang can think of it as a hole that has been dug deep, or a low canyon has blocked the passage. In the event of a flood, when the flood spreads beyond the embankment, the path of the river to the reservoir is opened and the river water is allowed to irrigate it. ”

Listening to Zhu Zhanji's words, Zhu Di suddenly said in confusion: "The river is flowing endlessly, no matter how big the reservoir you are talking about, how much water can it hold?" ”

Zhu Zhanji smiled and said, "Grandpa Huang, you shouldn't have really seen the flood, right?" In fact, the flood sounds continuous, but the real time of harm is only for a short period of time, and the construction of reservoirs in various places is just to unload the amount of water that exceeds the warning line in the flood at a critical time, and the reservoir can also discharge a part of the water when the storage capacity is high, and keep a normal flow of water to other places. ”

"In times of drought, the water stored in the reservoir can also be used as a backup source of water to avoid local droughts and lack of water."

"If there is really the kind of precipitation that is rare in the world for several months, the local government will also have time to organize manpower to evacuate the people along the coast in advance to minimize the losses."

Speaking of this, Zhu Zhanji stopped talking.

Everything that should be said has been said, and it doesn't matter if there are some omissions, it is not really formulating any measures to control the water.

"Grandson, I remember that you just said that trees on both sides of the river should not be cut down indiscriminately, and the mountains on both sides of the river should not be mined and excavated at will, so as to protect the normalcy of the land along the river and avoid land loss. It is understandable that the mountains on both sides of the strait are not allowed to be mined and excavated at will, but why are trees not cut down indiscriminately on both sides of the strait? What does this have to do with water? ”

Listening to the emperor's question, Zhu Zhanji was also a little embarrassed.

I just talked about what I thought of, and I forgot about the limitations of this era.

After thinking about it, Zhu Zhanji explained: "Grandpa Huang, have you ever dug up a tree? ”

Zhu Di said: "Naturally, I dug it." ”

"Then you didn't see the difference between land under trees and land without trees?"

Listening to Zhu Zhanji's words, Zhu Di recalled carefully.

Suddenly, Zhu Di seemed to think of something, and said, "You mean those rhizomes?" ”

Zhu Zhanji smiled and said, "Imperial Grandpa Shengming!" ”

Hearing this, Zhu Di suddenly chuckled and scolded: "Little rabbit, go on." ”

Zhu Zhanji nodded: "As the imperial grandfather said, the soil under the trees is interspersed with tree rhizomes, and the soil is relatively solid. The desert without trees is loose, and the desert to the north is caused by the lack of trees and perennial weathering. Conversely, if there were trees, the desert would not appear. The same is true for use along rivers. ”

"Ensure that trees are not cut down indiscriminately, so that the soil of the two river basins will remain normal, and it is not easy to divert and burst the embankment. On the contrary, the land is soft, the river is gone, and over time, the terrain changes, and the diversion and bursting of the embankment are inevitable. ”

Zhu Zhanji said that Zhu Di is really unheard of.

He had never thought or heard of trees having such an effect.

It really opened his eyes.

I couldn't help but be a little shocked in my heart.

Originally, he asked Zhu Zhanji about this matter, but he didn't think about letting him say any real governance measures, after all, this is an eternal problem. In addition to wanting to get the answers that Zhu Zhanji said for the first time, the more crucial thing is to extend it to the issue of the rule of man and the issue of corruption.

It is also to test whether his grandson has the talent and thinking in this area.

But he never thought that this kid really came up with such a set of instructions for him, at least at the moment, that sounded effective.

Zhu Di's heart couldn't help but rejoice.

And just as Zhu Di was thinking, the two people on the side looked at him, as if waiting for his attitude.

Zhu Di, who came back to his senses, also understood this, but just now he had already said that it was a test, could it be that he praised it a lot? Shocked?

Wouldn't that be too shameless?

"Ahem, that, what you said is not bad, although the cost is unimaginable, a little illusory, but for the sake of your youth, you have passed."

Hearing this, Zhu Zhanji also nodded and said, "The imperial grandfather is wise, the reason why the grandson didn't say it at first was because of this concern, and he felt that it was useless to say it, so he didn't mention it." ”

As soon as the words fell, Zhu Zhanji's face changed, and without waiting for Zhu Di to say anything, he hurriedly said: "Grandpa Huang, my grandson suddenly remembered that there was an urgent matter to deal with, if Grandpa Huang was fine, then my grandson would retreat first." ”

Although Zhu Di was a little surprised, he thought that the other party would continue to stay, and he didn't know how to end it, so he hurriedly sent him away.

And as Zhu Zhanji left, Zhu Di's face couldn't help but smile.

"This kid ....."

But when I looked up, I found that Dai Lun was still here, and I was stunned: "You haven't left yet?" ”

Dai Lun was stunned, and hurriedly said, "The minister will retreat." ”

But before he could leave, Zhu Di said again: "Wait, since you haven't left, I still have a few words to ask you." ”

Dai Lun hurriedly stopped again and said, "Your Majesty, please ask." ”

Zhu Di thought for a while and said, "The eldest grandson just left in a hurry, do you know what he's been busy with lately?" ”

Dai Lun replied: "Calculate the hour, it should be the time for His Highness to have afternoon tea." ”

Originally, he just casually said a casual sentence, and then said his real problem, but when he heard this afternoon tea, he was stunned.

"What is afternoon tea?"

Dai Lun said: "Back to Your Majesty, Your Highness will drink tea and rest at this hour every day. ”

Zhu Di suddenly said, "This stinky boy, I will enjoy it." ”

However, thinking that Zhu Zhanji was playing badminton and drinking afternoon tea every day, Zhu Di said: "After going down for a while, I will draw up a copy of the eldest grandson's daily living hours and what to do every day." ”

"The minister commands." Dai Lun replied happily.

After His Majesty tortured the eldest grandson, he actually took the initiative to ask for the eldest grandson's daily itinerary, which shows that His Majesty values the eldest grandson again.

And as the eldest grandson, he is naturally happy in his heart.

"Well, by the way, since you also listened to what the eldest grandson said just now, you can tell me, how about it?"

Zhu Di pretended to be casual and asked what he really wanted to hear.

Dai Lun faced the question raised by Zhu Di, and he also had a plan in his heart, and said: "Back to Your Majesty, it is a matter of government affairs, how dare Weichen speak falsely." But if it is just His Majesty's examination of the eldest grandson, as the division commander, Weichen feels that it is quite decent. ”

Zhu Di nodded noncommittally, but only he knew how satisfied he was in his heart.

Decent? The reply is neither humble nor arrogant, reasonable, modest and respectful, without the slightest juvenile arrogance, and the thinking is clear, the arguments are clear and novel, and the countermeasures are also extremely thorough and appropriate.

If it's just decent, then what is decent?

However, Zhu Di naturally would not say these words to Dai Lun, and he also knew very well that Dai Lun, as Zhu Zhanji's teacher, could only reply modestly.

But he still couldn't help but ask: "Then do you think the eldest grandson can take on a big responsibility?" ”

Dai Lun, who heard this, was shocked.

Not just surprise, but surprise.

But what is his own identity, he can only say euphemistically: "How dare Weichen say anything, but since His Majesty asked, Weichen only has three words." ”

"Good Saint."
