At first, I felt that the shopkeeper wanted to solve the problem of flooding, and there was nothing wrong with that.

After all, the top is the source, and if the water at the source is resolved, the floods below will be completely gone.

But at this moment, after looking at the situation here, he felt that something was wrong.

The lake is so huge, and it leans against the edge of the cliff and pours down. How easy is it to stop the water?

Looking at this situation, one knows that it is extremely dangerous, and it is impossible to succeed at all.

Lu Chensheng looked at the lake, looking at the water that kept sloping down from the cliff, and unconsciously frowned slightly.

To be honest, the above situation is really different from what Lu Chensheng thought.

The idea of ​​building a dam here was also abandoned by Lu Chensheng.

Under the current conditions, it is basically impossible to stop the dam.

If the technology is mature and there are all kinds of equipment, it can be done.

As long as you drill holes into the water at the beginning of the lake, and then use the poured cement pillars to drill down, so that the pillars form a circle, the water in the middle can be drained, and then continue to dig deep and lay a solid foundation. foundation.

In this way, a row of huge pillars can be built and the dam can be built.

It's just that there is no such condition at all now. How can a deep hole be made in the lake without equipment?

The initial idea really didn't work.

"Wait a while and continue to go to the front to have a look."

Lu Chensheng spoke up.

Gu Zhifang breathed a sigh of relief when he heard the words, it would be nice if the shopkeeper didn't want to build a dam on the lake.

If this is the case, I feel that no matter how much manpower and material resources are invested, it will be in vain.

After a group of people ate, they walked forward.

On this cliff, there is an extremely flat terrain with a lake on the side. Such terrain can be said to be unique.

Walking along the way, everyone realized that there are really many animals along the way, such as rabbits and sika deer.

But at the same time, they also saw a colorful giant tiger.

Probably because of the large number of people landing on Lu Chensheng, the giant tiger turned around and left after taking a look at the crowd.

The crowd didn't chase after them either, and now they were going to accompany Lu Chensheng to inspect the terrain.

The lake is too big, and it took several hours for the people to come to the end of the lake.

When they got here, everyone's faces froze.

In front is a big river that flows directly into the lake.

It's just this big river, everyone looked at it, and it seems that it is not easy to build a dam out of this big river.

With such a flat terrain, everyone really couldn't figure out how to build a dam.

"The shopkeeper?"

Gu Zhifang looked at Lu Chensheng. In his opinion, it is not at all difficult to build a dam here.

Chapter 426

Lu Chensheng watched from the side, but at this moment, there was a gleam of joy on his face.

"Fortunately, I have already prepared for the worst, and now this is not too bad."

Lu Chensheng breathed a sigh of relief, and then spoke.

When everyone heard this, they looked at Lu Chensheng suspiciously. In their opinion, it was very difficult to build a dam.

Why is the shopkeeper looking so happy.

Lu Chensheng didn't mean to talk nonsense with the people, but just waved and asked them to cut down some wood immediately and prepare to build a bridge.

Cutting down trees is extremely simple for nature, and after a while, the thick trees are cut down.

Lu Chensheng directed the crowd to simply combine the trees to form an arched bridge.

Subsequently, this simple bridge spans directly over the river.

Lu Chensheng crossed the river and went to the opposite side.

Seeing this, everyone followed one by one.

From here, they could see the frontier fortress, and if they looked carefully, they could vaguely see the city of Xing Seoul.

"How does the shopkeeper plan to control the water?"

Gu Zhifang was a little puzzled, so he just asked.

"Naturally it's diverted."

Lu Chensheng didn't show off, and responded directly.

If building a dam doesn't work, it's best to divert the flow.

Looking at the terrain in front of him, Lu Chensheng already had a good way to divert the flow.

There is a river on this side, and the diversion is relatively simple, otherwise, the lake on the side cannot be dug.

Not to mention the difficulty, if one is not good, it will be troublesome if the lake breaks its embankment.

It can be seen that the lake is still very deep, and the water storage capacity inside is extremely huge.

If the embankment breaks, even if the lake water does not pour into Da Cang Kingdom, it will be bad.

The water of Da Cang Kingdom basically comes from here, if there is no water once the embankment breaks.

This has a great impact on Da Cang Kingdom.

But if there is a river above, it is a better choice to divert from the river to a part of it.

"The shopkeeper, where do you want to divert it?"

Gu Zhifang was still puzzled, such a huge mountain range, below is the Da Cang Kingdom.

In how to divert them, wouldn't they still go to the country of Dacang? What's the point of this?

"Naturally, they were diverted to Xing Seoul City."

Lu Chensheng responded as a matter of course, you can see Xinghan City here, if you divert some of it to the past, a waterway can be built at that time.

With waterways, transportation will be infinitely more convenient, and the volume of goods transported will also increase several times.

I want Fu to build roads first, but this road is not easy to repair, and the factory of cement is too sluggish, and it is used in many places in Xing Seoul.

Even if you want to take it out and build a road, you can't do it.

In addition, even if the road is repaired, in terms of cargo throughput, the waterway is still larger.

At this moment, Lu Chensheng had an idea in his mind to dig out a waterway. Of course, this would require a lot of manpower, but thinking of the convenience that can be obtained after having a waterway, this is nothing.

Gu Zhifang was in a daze when he heard this, and then looked at the distance, diverted the water from here, and then built a waterway to come out. The project inside is extremely huge.

"But shopkeeper, if the waterway to be built is to be connected to the waterway of Dacang Kingdom, wouldn't the diverted water go back again?"

Gu Zhifang was a little puzzled.

"Look under this cliff, are there several valleys?"

At this moment, Lu Chensheng has brought the other party to the edge of the cliff.

The edge of the cliff here is not as steep as the previous one, but there are several more valleys.

Gu Zhifang glanced at it, then nodded.

"After the diversion, divert it here again. Once the water volume increases, some of it will flow towards the valley. Wouldn't the problem be solved by storing it in the valley?"

According to Lu Chensheng's vision, some of the diverted water will be stored in these valleys, and some will be consumed in the canals.

There are some canals that join Da Cang Kingdom.

In this way, it will basically have no impact on Da Cang Kingdom.

There are two water sources leading to Da Cang Kingdom. It is impossible for the water source to be exhausted, and the flood can be solved directly.

Originally, according to what Lu Chensheng thought, if there is no valley below, then it would be good to build some dams.

Under the cliff, rely on the cliff to build a dam, as a water storage place, and release the water when there is a drought.

Relatively speaking, it is very simple to build a dam by relying on the cliff. Given the current conditions in Xing Seoul, it can indeed be done.

But now it is not needed, there is a valley on the side that can be used, and the water can be directly diverted into this valley as a place for diversion.

Gu Zhifang was stunned for a while, and finally understood what Lu Chensheng said.

Such an approach, if done, should be able to solve the problem of flooding.

You know, when we were in Yunmeng City, the shopkeeper used the diversion method to solve the flood problem.

The Great Cang Kingdom did not adopt this method, entirely because there were too many branches, and wherever it was diverted, it would be a flood.

But Lu Chensheng went directly to the water source to solve the problem, and also found a place to divert the water, and there were several water storage places by the way, which can be said to have solved the problem perfectly.

Lu Chensheng took out a pen and paper, and began to draw the terrain here, as well as the planning of the canal.

After a while, Lu Chensheng handed a few pieces of paper to a person beside him.

"Send this thing back, let someone arrange to bring some people here to start water control, and bring all our captives down this cliff, let them start digging a canal, and build a dam in the valley to facilitate the introduction of the river Go in and store water."

Lu Chensheng said with an order.

"It's getting late today, let's go back tomorrow."

Lu Chensheng looked at the sky, and said again, it might be too dangerous to go back now when he was in the middle of the cliff, and the sky would turn dark.

The person in charge nodded and put the things close to his body.

Lu Chensheng continued to check the terrain, thinking about how to manage the water in his mind.

According to what was done in Yunmeng City, it can also be applied here. When summer comes, most of the water will be diverted away after the water volume increases.

And the diverted water source will also flow into the valley due to the sudden increase in water potential, and a small part will flow into the canal.

In this way, the flooding of Da Cang Kingdom should be solved.

However, the width of the diversion, the height of the river bed, etc., still need to be carefully considered.

Chapter 427 Profit

Those who went back soon brought a group of people to the top of the mountain.

Along the way, it was fortunate that Gu Zhifang brought people to meet him, otherwise, several people would have fallen.

It can also be seen from this that there are indeed not many people coming up here, and if one accidentally falls, it is a dead letter, and there is no treasure on it, so naturally no one will climb up here at will.

After arriving at the top of the mountain, Lu Chensheng immediately gave up his hands to start surveying and mapping, and the cement was also being transported up.

The delivery was quite difficult. Looking at the height of the mountain, Lu Chensheng wondered if his previous asking price was too much.

When Lu Chensheng began to divert the flow above, the captives in the other Xinghan City were also brought out, and they came under the mountain peaks on the side, and began to build dams with valleys and dug out canals.

Although the Grand Canal in the Sui and Tang Dynasties was extremely laborious and costly, it also played a very important role.

Now that Lu Chensheng is building this canal, it is absolutely necessary to invest in money, but when the canal is completed, the convenience will definitely exceed imagination.

Standing on the top of the mountain, Lu Chensheng could see people like ants below digging up little bits of soil and piling them up on both sides.Next to the valley, a dam is also being built at the moment to store water in it.

According to Lu Chensheng's idea, the dam is made into an arch, which can release the pressure of the water to both sides, and use the mountains on both sides to spread the pressure equally.

Everything is going on in an orderly manner, and the work is extremely smooth.

During the period, Da Cang Kingdom also sent people to see Lu Chensheng's water control progress, and to ask Lu Chensheng's water control plan and so on.

But after knowing that Lu Chensheng chose to start flood control on the Pingyun Mountain Range, he stayed at the foot of the mountain and did not see Lu Chensheng.

This mountain is too high, and the officials sent here simply cannot climb such a high mountain range.

Lu Chensheng didn't even think about going down to see the other party, so the matter was shelved.

The officials sent here only knew that Lu Chensheng had chosen the Pingyun Mountain Range to deal with the flood, and they didn't know anything else except this.

Seeing that Lu Chensheng hadn't come down for a long time, he could only go back with the news.
