Everyone on the embankment clenched their fists and breathed heavily.
They all spoke loudly.
"Please rest assured, Lord County Lord, we will do our best!"
"I would rather die of exhaustion on the river than anyone would be lazy."
"Three days are enough!"
The last sentence was said by Mr. Ye, which made Magistrate Wang's expression change, and he couldn't help but look over with a little surprise.
When he went to see Mr. Ye before, he still said such confident words.
However, Mr. Ye didn't explain anything. He only looked directly into Magistrate Wang's eyes, seemingly confident.
Magistrate Wang understood the situation and didn't ask any more questions. He immediately handed over all the calculations to Mr. Ye.
Everyone immediately dispersed and prepared.
The river channel selected for digging canals is extremely narrow, and the sound of surging water can be heard from a long distance.
It can be seen that the water potential is turbulent and the drop is not small, which is very suitable for flood discharge.
Everyone came closer to take a look and found that the slope of the river was indeed extremely steep, and the rocks on the shore were angular and angular, obviously being impacted by the current from upstream.
It can be inferred that the soil in the mountains upstream must be loose, and the mountains and forests are sparse, so the water and soil cannot be conserved.
But the upper reaches are full of deep mountains and old forests, so how could there be so few trees?
Now is not the time to think about these things, flood relief is the most important thing.
After walking a little further, Mr. Ye raised his hand to stop.
Instruct several people to step forward and carefully measure the heights of many river embankments.
They also arranged for people to tie ropes and ride bamboo rafts deep into the river, and inspected several riverbed conditions.
However, these are still relatively simple measurements, and the most complicated ones are long-distance measurements of gentle slopes and depressions.
With miles of gentle slopes and extremely irregular depressions, it is definitely very difficult to measure each section accurately.
Everyone racked their brains and tried several times to no avail, and the measurement speed quickly slowed down.
It was only then that Mr. Ye realized that the secret arithmetic skills he had learned before were actually not enough!
Looking at the frowning faces of everyone, Chen Ping did not try to steal the limelight.
Instead, he walked to Mr. Ye and whispered a simplified version of the light and shadow measurement method.
The method of light and shadow measurement.
In fact, it’s not that it doesn’t exist in this world at all, it’s just that it’s still in a very early stage and the restrictions are not small.
For example, on a sunny day, you can erect a bamboo pole of a fixed length, and then use the ratio of the length of the bamboo pole to the shadow of the mountain to calculate the height of the mountain.
But there was no sun at this time, and the continuous rain made everyone's vision blurred, and even the shadows were gray and weak.
The light and shadow measurement method provided by Chen Ping can be used smoothly even on a rainy day like today.
This made Mr. Ye look at him with even more admiration.
Mr. Ye calmly made arrangements.
In the eyes of outsiders, this method was proposed by Mr. Ye.
This was also Chen Ping's own request. He felt that he was too young to be credited with pioneering this method.
Moreover, if this matter spreads, everyone will think there is something fishy.
A child who had never been exposed to water conservancy and civil engineering actually created a whole set of measurement methods that can measure complex terrain on rainy days?
Who dares to believe it?
The cadres who were doing the work didn’t realize there was anything strange about it.
But after the students from the county school thought about it carefully, their expressions became more and more excited.
This is not some low-level craft.
It is a secret technique that must be used in every large-scale civil engineering and water conservancy project.
If this is the first of its kind, it will surely benefit us forever!
Mr. Ye taught them such secret techniques without reservation, which was equivalent to giving them a stable retreat in the future.
If anyone has trouble taking the imperial examination in the future, they can at least rely on this secret technique to find a job that will make them a living.
The sensible students are full of respect and gratitude to Mr. Ye.
Chen Ping really didn't expect that the measurement method would have such a side effect, which made everyone excited and found it extremely interesting.
But facing the admiring gazes of everyone, Mr. Ye felt a little ashamed and his face turned red.
After all, this was a secret technique that had taken possession of his disciples. No matter how good the reason was, he could not rest at ease.
Fortunately, Chen Ping also saw the teacher's mentality, smiled and said disapprovingly: "Why should the teacher care about these trivial details?"
"What we are doing now is related to the safety of countless people in Yongshun County."
"For this purpose, all methods must be used, all means must be used, and the overall situation must be the most important thing!"
Mr. Ye rolled his eyes angrily and said: "If you have the energy to play tricks, you might as well go measuring with those county students."
"By the way, didn't you say last night that there was still a strange trick yet to be used? As long as this trick is used, the most suitable flood outlet will be found quickly."
Chen Ping put away his obedient expression and said solemnly: "Teacher, please don't worry, He Qingxuan has been prepared for my strange move."
"As long as the county students have measured the elevation and distance of each place, and coupled with my unique skills, they will definitely be able to determine the flood outlet very quickly."
"At that time, as long as the teacher has planned the location and route, we can start excavation."
As for what that strange move was, Chen Ping didn't say anything last night, he still wanted to hide it.
Last night, Mr. Ye relied on his trust in his disciples. Although he was in an urgent mood, he did not delve into it deeply. He just waited patiently until now.
But this was already at the edge of the flood discharge channel, and Chen Ping was still showing off. Mr. Ye's eyes widened.
He slightly bent his fingers and raised his arms, and a "murderous aura" that Chen Ping was very familiar with instantly hit him.
Sensing something was wrong, Chen Ping hurriedly took two steps back, covered his little head, and shouted repeatedly: "Qingxuan, get my sandbox model quickly!"
"Come and help!"
Mr. Ye was startled when he heard this and murmured: "Sand table model? What is that?"
When He Qingxuan and a servant came over carrying a huge object.
Mr. Ye finally knows what a sandbox model is.
It was just a three-foot-square wooden board with layers of fine sand stacked on it.
But this fine sand has already initially sketched out the shape of a river, with its curves, dangerous shoals, and slope shapes, which are very similar to the Cang River in front of you.
On both sides of the river outlined by the fine sand, He Qingxuan had already drawn several thin lines, making the waterway clear.
This chapter is not over yet, please click on the next page to continue reading!
The Canghe River has nine twists and turns. It used to be beyond the reach of the eye, but now it is clearly visible on this sand table.
Seeing this, Mr. Ye felt as if a mysterious light exploded in his heart, and he suddenly became enlightened!
In the past, in water conservancy matters, many problems caused by complex terrain and heavy mountains were immediately solved.
If we could have thought of this wonderful method before and used fine sand to shape the rivers and mountains in the same way as the gourds, how could there be so many problems?
During spring floods and summer floods, the Ministry of Works spends a lot of time and energy building embankments and dams.
It is often necessary to send a large number of manpower to measure river channels and explore sites.
Not to mention the consumption of silver, officials were often injured or killed during the investigation.
Why has no one thought of this sandbox model?
In the final analysis, this is not some profound knowledge, it is just a layer of window paper that has not been penetrated.
Overwhelmed with joy, Mr. Ye was filled with emotion.
But when his eyes swept across the high hillside and the dam at the source, he felt horrified!
He quickly stepped forward to hold Chen Ping and He Qingxuan, and whispered.
"Hurry and hide it, don't show it randomly!"
"This thing may cause death!"
Chen Ping and He Qingxuan looked confused.
How can there be a fatal disaster? Isn’t this a good thing?
Naturally, the teacher would not deliberately intimidate him. Looking at the serious and tense face, Chen Ping quickly covered the sand table.
The three of them moved to a quiet place.
Ye Laofang just scolded: "Every bustle in the world is for profit, and all the hustle and bustle in the world is for profit. Do you know how much benefit you have taken out!"
"With this device, not only water conservancy works will become simpler, but also a lot of trouble will be saved during marching and fighting."
"You and I have no official protection now. Can a county magistrate alone really protect the benefits brought by such rare things?"
He Qingxuan was completely stunned.
Chen Ping was startled when he heard this and realized that he had been careless!
He had just thought that this sandbox model was just something from the past life, and it was not high-tech, so he just took it out.
But one thing they have forgotten is that for an agricultural society, the truly precious things are not just high technologies.
High-tech things often require many conditions to support their use.
On the contrary, it is this kind of thing that is only separated by a layer of window paper, and once it is pierced, it can bring about huge changes in the society in the agricultural era, which is the most attractive.
After understanding this, Chen Ping quickly said: "Teacher, let's destroy the sand table and find other ways to locate the flood outlet."
Mr. Ye had a complex look on his face. After thinking for a while, he shook his head and sighed: "If we let the people of Yongshun County bear more risks for our own purposes, I will have read decades of sage books in vain." p>
He ordered: "This matter cannot be spread to outsiders, but this method can continue to be used."
"You quietly move the sand table back to the hayloft room, and I will record all the measurements one by one, and you will add them to the sand table when I get back."
"When we find the accurate flood outlet on the sand table, we will destroy it immediately!"
Mr. Ye's reaction was extremely quick.
This method can not only quickly complete the flood discharge task and solve the crisis of the people in the county, but also keep the secret of the sand table model as much as possible.
