The repair of the Longshou Canal encountered problems.

It's not the section that passes through Shangyan Mountain.

With cement, an excellent adhesive material, this distance in Shangyan Mountain is not difficult to repair.

It's just a bit of a lot of work and time.

It is still not a problem to proceed step by step.

The problem appeared in these dozens of miles of canals behind Shangyan Mountain.

The soil here is too loose, and over the years, with the power of the water, the entire canal bed has been cut down a lot.

As a result, the water surface in the canal will be much lower than that of the fields on both sides.

At the same time, the main canal is so low, so if you want to have water flowing from the branch canal that separates from the main canal, the branch canal also needs to be dug down vigorously.

This will undoubtedly make it much more difficult to repair the canals.

I increase the quantity of work by a lot!

If that's all it takes, Jia Xu doesn't feel melancholy, it will take more time and more labor.

Take your time, you can always get it right.

But it's not that simple.

Originally, the main canal was cut down sharply, so that the main canal was far below the ground, and at this time, if the branch canal was repaired and excavated according to such standards, the effect presented would be the same as that of the main canal.

It is possible to access water, but it is too difficult to use the water from the canal to irrigate the ground.

After all, the riverbed is too low, the water level is far below the ground, and the water itself can't reach the ground at all!

Even if people carry water from the nearest canal to water the ground, such a high distance is very difficult.

That's how the problem arises, stuck here.

Jia Xu is indeed a smart person.

However, people often specialize in the arts.

Jia Xu is very smart, but he is not proficient in water conservancy.

It's okay to command people to repair the existing canals step by step, but when you really encounter this kind of extremely difficult problem, it is really difficult to solve it!

"You can't just raise the entire riverbed......

In this way, the amount of work can be even larger!

In addition, if the entire riverbed is raised, the water will be too high at the head of the canal, and it will be difficult for the water to enter it......"

Jia Xu thought hard about this, only to feel full of sorrow.

The officials under him, as well as some managers, also had no solution.

Jia Xu, who has always been smart, has never been so melancholy......

"Captain, someone came to ask for a meeting, saying that there is a way to solve the difficulties encountered so far."

After a while, someone came to tell Jia Xu and said this.

When Jia Xu heard this, he immediately stood up.

"Hurry up, please!"

This is really the news he wants to hear the most in this period of time.

Saying this, he immediately went out with the man to meet the man who was going to offer the good prescription.

It didn't take long for Jia Xu to meet the person who said that he wanted to offer a good prescription.

After seeing this person, Jia Xu couldn't help but be stunned in his heart.

Because the person in front of him is too young!

It is not an exaggeration to call him a teenager.

Gu Jia Xu visually measured that the person in front of him who said that he could offer a good plan to solve the problem of the canal would definitely not be more than sixteen years old!

However, Jia Xu is different from ordinary people.

He was amazed at the man's age, but he wouldn't show it.

In my heart, I didn't despise the person in front of me because of this.

He has been smart since he was a child, and he clearly knows that when looking at people, you can never look at them only from their age and appearance.

In this case, you will definitely miss out on a lot of good talents.

At the moment, he bowed to the person in front of him dressed as a country boy, and asked seriously: "I don't know where this young man is from, please give me advice." ”

This country boy also hurriedly returned the salute to Jia Xu.

opened his mouth and said: "Little, small, the kid is, yes, yes, is the wind, the wind, the wind man, called, called, called Ma Jun, Jun ......"

may have exposed his stuttering as soon as he opened his mouth, or he was anxious about speaking for himself, Ma Jun's face turned red at this time.

Although Jia Xu was surprised again, he didn't show it.

Waited patiently for a while, and when Ma Jun finished speaking, he said with a smile: "I heard that you have a way to solve the problem encountered in repairing the Longshou Canal?"

Go to my tent and talk to me properly. ”

As he spoke, he invited Ma Jun to go to the camp with him.

This kind of treatment made Ma Jun, who had to hesitate again and again, and only then mustered up the courage to come, and was already ready to be humiliated, felt very surprised.

After the accident, it is easy and happy.

At the same time, there are some things in my heart that should be like this.

People say that Uncle Liu Huang loves the people, but now it seems that it is true!

One of his lieutenants was able to receive an unknown country boy like this, without belittling or laughing at him because of his age, status, and stuttering.

As you can imagine, what you know on weekdays is true!

"The repair of the Longshou Canal is related to the future life and survival of many people, and I also ask Xiaolangjun to give advice."

After coming to the tent, Jia Xu solemnly saluted Ma Jun and asked very sincerely.

If it was placed in the past, although Jia Xu would not despise Ma Jun who came here, he would never be able to do it now.

After following Uncle Liu Huang for a long time, he will unconsciously be influenced by Uncle Liu.

Of course, more importantly, this time the repair of the Longshou Canal was handed over to him by Uncle Liu Huang.

This is a great trust and value for him.

Moreover, this repair of the Longshou Canal is really a matter of benefiting the country and the people.

It is necessary for him to do his duty.

Jia Xu's gift immediately flattered Ma Jun.

He hurriedly saluted Jia Xu in return, and waved his hand again and again: "Make, make, can't, get." ”

Subsequently, Ma Jun began to tell his plan in its entirety, without even a little excuse or sale.

This made Jia Xu sigh in his heart, no wonder Uncle Huang was always so approachable and such a courteous corporal.

Now, I have learned from Uncle Huang to do this, and the effect is really very good.

It seems that I still have to learn more from Uncle Huang in the future!

In Jia Xu's patient waiting, he gradually understood what Ma Jun meant.

The difficulty they face now is that the canal is heavily cut down, and the water surface is too far from the land on both banks.

Ma Jun's plan is to raise the water surface!

It's not the kind of soil that goes to the bottom of the canal for dozens of miles, so that the canal bed rises upward.

Instead, in the midst of these dozens of miles of canals, some small dams were built in stages.

The dam doesn't have to be too high, it doesn't have to be higher than the embankments on both sides.

The main function of this small dam is to store water!

With this embankment, when it is blocked in the canal, the water level in the canal will rise accordingly.

On the premise of not exceeding the embankments on both sides, the water level can be raised as high as the dam is built.

After waiting for the first stage to fill up, water will flood over the top of the small dam and pour into the next stage.

Once the second stage is full, the third stage will begin......

When the water level of the main canal is raised, the rest of the many branch canals that exist like cobwebs on the main canal do not need to be dug as deep......

Compared to the huge amount of work of filling in the bottom of a large number of main canals and digging many branch canals deeper, it is too easy to build some small dams!

Moreover, the effect is surprisingly good!

Of course, in the past, it would have been too easy to build a flood dam in a trunk canal that had been washed and soaked by the flow of water day and night, due to the constraints of adhesive materials.

But now, with the cement auspiciousness that Uncle Liu Huang got from dreaming of the turtle, it is not a problem to build such a flood dam!

"Good! That's great! ”

After Jia Xu completely understood what Ma Jun meant, he couldn't help but follow Uncle Liu's example, and took the hand of the stuttering teenager Ma Jun, extremely excited, full of emotion and praise.

"As soon as Xiao Langjun's plan came out, the difficulties encountered in the downstream of Longshou Canal were solved!

And it's very ingenious!

It's really a clever breakthrough!

I will definitely report Xiao Langjun's merits and deeds to Uncle Liu Huang, the general of Tuntian Zhonglang, so that Uncle Huang knows Xiao Langjun's talent and achievements! ”

Ma Jun's complexion turned red again after Jia Xu said something.

"Make, make, can't, get, Ma Jun, Jun, just, yes, dedicate, dedicate, dedicate one, a little small, small, small policy, policy, when, when, can't, got, captain, captain, this, so ......"

Jia Xu waited until Ma Jun finished speaking, and immediately shook his head with a smile and said: "Xiao Langjun is polite, this is not a small policy, this is a big policy related to estimating people's livelihood!"

If Uncle Huang knew about Xiao Langjun's strategy and Xiao Langjun's talent, he would definitely be very happy! ”

After saying these words, Jia Xu immediately threw an olive branch to Ma Jun.

"Xiao Langjun, repairing the canal, just need a talent like Xiao Langjun to help the people, settle down as soon as possible, Jia Xu is not talented, and is willing to hire Xiao Langjun as the captain of Tuntian, and please Xiao Langjun not refuse."

Jia Xu said this and solemnly saluted Ma Jun.

Ma Jun is just a rural boy, and because of his stuttering, he has been ridiculed and looked down upon by many people since he was a child.

Now that I have come here, I am so courteous to Jia Xu.

Jia Xu told the family and the country again.

In such a situation, Ma Jun naturally has no reason to refuse.

As a result, a country boy before has now become a lieutenant of Tuntian.

And next, Ma Jun's performance also proved to Jia Xu that Jia Xu's vision and trust were not wrong.

Not only the solution to the problem proposed by Ma Jun is very easy to use.

Ma Jun, a stuttering teenager, also has excellent insights into the construction of water canals.

The location and height of the dam did not need to be thought about by Jia Xu at all, and Ma Jun was able to handle it properly.

It's much better than Jia Xu, a person who is not proficient in water conservancy.

Moreover, in addition, Ma Jun is often able to put forward constructive suggestions on the repair of branch canals.

There are many places, just according to his opinion, a small change has been made, and it can immediately show good results!

"This time, I really picked up a treasure!"

Jia Xu looked at Ma Jun, who rolled up his trousers and directed the people to build a canal there, with a smile on his face, and said with emotion.

Not to mention how comfortable it is in my heart.

……

"This time, I really picked up a treasure!"

Almost at the same time, Liu Cheng, who presided over the repair of Zheng Guoqu, held Jia Xu's letter in his hand and said this excitedly.

Ma Jun!

This is Ma Jun!!

There is no need to look at what Jia Xu said with himself about Ma Jun's good strategy this time.

Just look at the name Ma Jun mentioned in Jia Xu's letter, as well as the characteristics of stuttering, Liu Chengcheng will become more excited than Jia Xu.

Because, what he knows about Ma Jun's deeds is much more detailed than what Jia Xu wrote in the letter!

And so much, more!

For example, the guide car was restored, and the keel waterwheel was manufactured, and the rotary stone machine was manufactured......

In his later years, after seeing the Zhuge Repeater invented by Prime Minister Zhuge Cheng, he started to further improve the Zhuge Repeater.

The power of Zhuge Repeater's crossbow soared exponentially!

This is the most bullish and dazzling mechanical inventor in the Three Kingdoms period!

History calls it the world's famous coincidence!

It is a character whose name is ranked behind the big guys such as Gong Loser Ban, Mo Zhai, and Zhang Heng in history!

Now, the world's famous coincidental and newly grown people have come under his command, and as soon as he made a move, he showed such extraordinary talents, living up to his reputation in history.

In such a situation, how could Liu Cheng not be happy?

For Liu Cheng, Ma Jun's role is even far beyond that of many top strategists and fierce generals of this era.

Because although the top strategists and brave generals are rare, they are not one after all, and some can be obtained.

However, a talent like Ma Jun is unique!

Moreover, Liu Cheng, who came from later generations, is different from most people in this era.

For Ma Jun's talents, he really attaches great importance to them.

And clearly know that Ma Jun's talent in 'strange skills', once used well, will be able to have a great effect!

This thing, and ideological and cultural construction, one is inward, and the other is inward.

Both are extremely important things, and one is indispensable!

Liu Cheng found Xun You, Sima Lang and others, and shared with them the methods taken by Ma Jun in the repair of the Longshou Canal mentioned in Jia Xu's letter, and Xun You and others couldn't help but be amazed.

"That's really a good idea!"

Xun You couldn't help but praise loudly, and Sima Lang couldn't help but nod again and again.

"Not only does this increase the surface of the water, but it also stores water.

Even in the event of a major drought, the water inflow into the canal decreases, but with this water storage function, it can last for a long time......"

Gu Yong and Gu Yuan sighed, full of admiration and analysis.

Then they began to discuss how to apply Ma Jun's recipe to Zheng Guoqu......

Liu Cheng left Zheng Guoqu, which was being repaired, and went all the way to Fengyi County.

He's going to meet his chief engineer!
