The repair of Longshou Canal encountered problems.
It's not the section that goes through Shangyan Mountain.
With cement, an excellent binding material, it is not difficult to repair this section of Shangyan Mountain.
But it was a bit laborious and time-consuming.
If you proceed step by step, it won't be a problem.
The problem occurs in the dozens of miles of water canals after Shangyan Mountain.
The soil here is too loose. Over the years, with the power of water flow, the entire canal bed has been cut down a lot.
The consequence of this is that the water surface in the canal will be much lower than the fields on both sides.
At the same time, if the main canal is so low, if you want the water to flow in the branch canals branching off from the main canal, the branch canals also need to be dug down hard.
This will undoubtedly greatly increase the difficulty of repairing canals.
Increase the amount of work!
If this was just the case, Jia Xu wouldn't feel melancholy. It would be fine if he spent more time and more labor.
Take your time and you can always get it done.
But the problem is not that simple.
Originally, the main canal was cut too far downward, making the main canal far below the ground. If we continue to repair and excavate the branch canals according to this standard, the effect will be the same as that of the main canal.
It is possible to pass water, but it is too difficult to irrigate the ground with water from the canal.
After all, the river bed is too low, the water surface is far below the ground, and the water itself cannot reach the ground!
Even if people carry water from the nearby canal to irrigate the ground, it is not easy at such a high distance.
The problem arises like this, and it's stuck here.
Jia Xu is indeed a smart man.
However, people often have specializations in their professions.
Jia Xu was very smart, but he was not proficient in water conservancy.
It's okay to direct people to repair existing ditches step by step, but when you encounter such an extremely difficult problem, it's really difficult to solve it!
"We can't just improve the entire riverbed...
In this case, the amount of work will become even greater!
Moreover, if the entire river bed is raised, the water intake at the head of the canal will be too high, making it difficult for water to enter..."
Jia Xu thought hard about this matter, but felt full of sorrow.
The officials under him, as well as some managers, also had no idea at all.
Jia Xu, who has always been smart, has never been so melancholy...
"Captain Lieutenant, someone came to see me and said that there is a way to solve the difficulties we are currently encountering."
After doing this for a while, someone came to report and said to Jia Xu.
When Jia Xu heard this, he immediately stood up.
"Please come quickly!"
This was really the news he wanted to hear most in a while.
Saying this, he immediately followed the man out and went to meet the man who was about to offer him the medicine.
It didn't take long for Jia Xu to meet someone who said he would offer a good prescription.
After seeing this person, Jia Xu couldn't help but be stunned.
Because the person in front of me is really too young!
Calling him a young man is not an exaggeration at all.
Ju Jiaxu made a visual inspection and found that the person in front of him who claimed to be able to offer good suggestions to solve the drainage problem was definitely no older than sixteen!
However, Jia Xu is different from ordinary people.
Although he was surprised at this man's age, he would not show it.
In my heart, I didn't look down on the person in front of me because of this.
Being smart since childhood, he knew clearly that one should never judge people based on their age and appearance alone.
In this case, a lot of good talents will be missed.
Immediately, he bowed his hands to the man in front of him who was dressed as a country boy, and asked seriously: "I don't know where this young man is from, please enlighten me."
This country boy also quickly returned the favor to Jia Xu.
He opened his mouth and said: "Xiao, Xiao, boy is, is, Fufeng, Feng, Fengren, call, call, call Ma Jun, Jun..."
Maybe he exposed his stuttering problem as soon as he opened his mouth, or maybe he was anxious about speaking for himself, but Ma Jun's face turned red at this time.
Although Jia Xu was surprised again, he didn't show it.
After waiting patiently for a while, when Ma Jun finished speaking, he smiled and said: "I heard that you have a way to solve the problems encountered in repairing Longshou Canal?
Come on, come to my tent and talk to me properly."
With that said, he invited Ma Jun to follow him to the camp.
Such treatment made Ma Jun, who had hesitated for a long time and had just summoned up the courage to come, and was already prepared to be humiliated, feel very surprised.
After the accident, there was relief and joy.
At the same time, some things that should be like this appeared in my heart.
People say that Uncle Liu is benevolent and loves the people. Now it seems that it is indeed true!
A field captain under him was able to receive an unknown country boy like this without despising or ridiculing him because of his age, identity, and stuttering.
It is conceivable that what I usually know is true!
"The repair of Longshou Canal is related to the future lives and survival of many people. Please give me your advice."
After arriving at the tent, Jia Xu solemnly saluted Ma Jun and asked sincerely.
If it were in the past, although Jia Xu would not despise Ma Jun who came here, he would never be able to reach the point where he is now.
After following Uncle Liu Huang for a long time, he would be influenced by Uncle Liu unconsciously.
Of course, what is more important is that Uncle Liu left it to him to repair Longshou Canal this time.
This is a great deal of trust and respect for him.
Moreover, the repair of Longshou Canal is really a matter of benefit to the country and the people.
He must do his duty to it.
This gift from Jia Xu immediately flattered Ma Jun.
He quickly returned the greeting to Jia Xu and waved his hands repeatedly: "Make, make, make it impossible, get it."
Afterwards, Ma Jun began to reveal all his plans without any excuses or compromises.
This made Jia Xu sigh in his heart, no wonder the emperor's uncle was always so approachable and courteous.
Now, I am learning from the emperor's uncle to do this, and the effect is indeed very good.
It seems that I will still have to learn more from the emperor’s uncle in the future!
As Jia Xu waited patiently, he gradually understood what Ma Jun meant.
The difficulty they face now is that the canal is severely undercut and the water surface is too far from the land on both sides.
The plan Ma Jun gave was to raise the water level!
It's not the kind of improvement where soil is added to the bottom of the canal for tens of miles to make the canal and river bed rise.
Instead, some small dams were built in stages among the dozens of miles of canals.
The dam does not need to be too high and does not need to be higher than the embankments on both sides.
The main function of this small dam is to store water!
Once this dike is blocked in the canal, the water surface in the canal will rise accordingly.
As long as the dam does not exceed the embankments on both sides, the water level can be raised as high as the dam is built.
After the first stage of water is filled, the water will overflow from the top of this small dam and be injected into the next stage.
After the second stage is filled, it will enter the third stage...
After the water level of the main canal is raised, the other numerous branch canals that exist like spider webs that rely on the main canal no longer need to be dug so deep...
Compared with the huge amount of work required to fill up the bottoms of a large number of main canals and dig deep into many branch canals, it is really easy to build some small dams!
Moreover, the effect is surprisingly good!
Of course, in the past, due to the constraints of adhesive materials, it was not easy to build such an overflow dam in a main canal that would be washed away and soaked by water day and night. It would collapse too easily.
But now, with the cement auspiciousness that Uncle Liu Huang got from dreaming about the turtle, building such a flood dam is not a problem at all!
"Okay! It's really good!"
After Jia Xu thoroughly understood what Ma Jun meant, he couldn't help but imitate Uncle Liu Huang, and took the hand of Ma Jun, a young man who stuttered. He was extremely excited and praised him repeatedly with emotion.
"As soon as Xiao Langjun came up with this plan, the difficulties encountered in the lower reaches of Longshou Canal were easily solved!
And it’s extremely clever!
It is true that ingenuity can overcome the odds!
I will definitely report Xiao Langjun’s merits and deeds to Uncle Liu, the general in the field, so that the emperor will know Xiao Langjun’s talents and achievements!”
After what Jia Xu said, Ma Jun's face turned red again.
"Make, make, not, get, Ma Jun, Jun only, it is, offer, offer, offer a, a little, a small, small, small policy, policy, when, when, should not, get, Xiaowei, Wei
This, this..."
Jia Xu waited until Ma Jun finished speaking, then immediately shook his head with a smile and said: "Young man, you're welcome, this is not a small policy, it is a major policy related to people's livelihood!
If the emperor's uncle knows about the strategy and talents of Xiao Langjun, he will definitely be very happy!"
After saying these words, Jia Xu immediately extended an olive branch to Ma Jun.
"Xiao Langjun, we need people like Xiao Langjun to repair the canals to help the people settle down as soon as possible. Jia Xu is not talented and is willing to hire Xiao Langjun as a field captain to work on it. Please don't refuse, Xiao Langjun."
Jia Xu said this and saluted Ma Jun solemnly.
Ma Jun was just a country boy, and because of his stutter, he was ridiculed and looked down upon by many people since he was a child.
Now that I am here, I am treated so politely by Jia Xu.
Jia Xu once again told about his family, country and world.
Under such circumstances, Ma Jun naturally had no reason to refuse.
As a result, the former country boy has now transformed into a military captain.
And in the following, Ma Jun's performance also proved to Jia Xu that Jia Xu's vision and trust were correct.
Not only the solution to the problem proposed by Ma Jun is very useful.
Ma Jun, a young man who stutters, also has excellent insights into building canals.
Jia Xu didn't need to worry about the location and height of the Man Dam. Ma Jun could handle it properly.
It is much better than what Jia Xu, a man who is not proficient in water conservancy, could do.
Moreover, in addition, Ma Jun is often able to put forward constructive opinions on repairing branch canals.
There are many places where, just by making a small change based on his opinions, good results can be seen immediately!
"This time, I really found a treasure!"
Jia Xu looked at Ma Jun, who was rolling up his trousers and directing the people to build canals, with a smile on his face and said with emotion.
Not to mention how comfortable I felt in my heart.
…
"This time, I really found a treasure!"
Almost at the same time, Liu Cheng, who was in charge of the repair of Zheng Guo Canal, held a letter from Jia Xu in his hand and said this with excitement.
Ma Jun!
This is Ma Jun!!
There is no need to look at what Jia Xu said to himself about Ma Jun's good strategy this time.
Just look at the name Ma Jun mentioned in Jia Xu's letter and the characteristics of stuttering, and Liu Chenggong will become even more excited than Jia Xu.
Because what he knew about Ma Jun's many deeds was much more detailed than what Jia Xu wrote in the letter!
Much more, too!
For example, restore the compass car, create a keel waterwheel, a rotary stone machine...
In his later years, after seeing the Zhuge Liannu invented by Prime Minister Zhuge, he began to further improve the Zhuge Liannu.
This caused the power of Zhuge Liannu to increase exponentially!
This was the most awesome and dazzling mechanical inventor during the Three Kingdoms period!
History calls it a clever name in the world!
They are people whose names are ranked behind big names like Gongshu Ban, Mo Zhai, and Zhang Heng in history!
Now, the newly emerging and mature Tianxia Mingqiao came under his command. As soon as he took action, he showed such extraordinary talents and lived up to his reputation in history.
Under such circumstances, how could Liu Cheng be unhappy?
For Liu Cheng, Ma Jun's role far exceeded that of many top advisers and generals of this era.
Because although top advisers and brave generals are rare, they are not just one after all. You can get some.
However, a talent like Ma Jun is unique!
Moreover, Liu Cheng, who came from later generations, was different from most people of this era.
He really valued Ma Jun's talents.
And he clearly knew how great an impact Ma Jun's talent in 'skills and tricks' would have if used properly!
These things, including ideological and cultural construction, one is internal and the other is internal.
Both are extremely important things and one cannot exist without the other!
Liu Cheng brought Xun You, Sima Lang and others over and shared with them what Jia Xu's letter said about the methods Ma Jun had adopted in the repair of Longshou Canal. Xun You and others could not help but be impressed by it.
"This is really a good idea!"
Xun You couldn't help but praise aloud, and Sima Lang couldn't help but nod his head.
“This method can not only raise the water surface, but also store water.
Even if there is a severe drought and the water inflow into the canals is reduced, with this water storage function, it can last longer..."
Gu Yong and Gu Yuan sighed and analyzed with admiration.
Then they began to discuss how to apply Ma Jun's recipe to Zheng Guo Canal...
Liu Cheng left Zheng Guo Canal, which was being repaired, and went all the way to Feng Yi County.
