81 Episode 81 Flood Control

"Mr. Almus. First of all, please read a rough overview."

Ismail gave me a plan.

It's very rough, not very, but not enough to be a plan.

But on the third day, it's fine to write just by looking at it.

"The geological survey of the river water and the planned construction site for the capital will be transformed into Tetra-sama ... Nicolaos is awaiting a report. Therefore, we will make minor corrections depending on the results of the survey."

"HM……"

The land that Ismare has designated as a construction site is located slightly east of the junction of the three rivers.

According to the plan, the land around here is slightly west, so when the river overflows, the water goes west.

Therefore, it is safe to build a building on the east side.

There are seven gentle hills in the area, and it is said that there is no danger of flooding if important facilities are built on the hill.

However, once a decade of flooding occurs, the lowlands below the hills may be submerged, even if the hills are okay.

Flood control is essential, as it is expected that houses for the common people will be built in the lowlands below the hills.

This is the report on the capital.

"What about flood control?"

"Flood control is going to make a concrete plan after hearing the report, but ... I'm going to tackle it with diversion and embankment. It's a troublesome place, but it's not a rampage river. "

"Diversion and embankment?"

Water diversion is good. It also becomes an irrigation facility and reduces flood damage.

Two birds with one stone.

"Oh, yes, there's actually something I want to show you."

When I clapped my hand, the slave brought the example in a couple.

A gray liquid and a gray stone.

"this is?"

"It's like concrete. It's usually muddy, but it hardens over time and it gets this hard."

I hand the hardened concrete to Ismare. Ismare looks at the concrete with interest.

"Mix volcanic ash and lime. Use as many materials as you like."

"Ko, this is ... if you have something so useful, let me know sooner!"

Ismare came to me with an excited face.

It took a long time to develop, so I couldn't tell. It is not good to make bran rejoice.

"So spend that many people and how long do you intend to spend? I don't want to wait too much ..."

"First of all, flood control ... it's a year of diversion work and dike construction, and we'll spend four more years strengthening dikes and diversion and applying irrigation. As long as it doesn't break down. ''

Five years ...

Is this the longer one? Is it short? ... I don't know.

"It's a metropolitan construction, but as I explained earlier, I'll make it from the top of the hill. It's a good idea to start one year after the flood control work. It would have been three years to build a government-owned facility, and at least the capital function could be restored in four years. "

Hmm ... I've heard from you a little short estimate ...

"How many people do you need? To go as planned"

"Two thousand people. Considering the national power of the country, I can't help cultivating 4,000 married women at all times. However, if it's too small, it takes too much time, and on the contrary, it costs too much. 2,000 people are the best to do the construction. ''

Two thousand people ...

Our standing army is a thousand. So they are separating 3,000 people from agriculture and running into military and construction.

About 1.2% of the population. Well, it's a manageable level. It's a little headache to keep it for five years, but it doesn't even fall.

"And that's Ismare. In fact, I want to lay a road ... can I do that?"

"Is it a road?

so. There are simple roads.

In other words, where people walk, the ground is stomped on and becomes a natural road.

It is about four meters wide and fairly wide. There is no inconvenience on a sunny day.

But on a rainy day the story is different.

Because it is made of soil, when it rains it becomes flooded and muddy.

Legs are taken. The carriage is immersed. The horse falls ...

Good infrastructure ... but not very much.

I would like to increase my tax revenue by increasing my commercial activity.

"I want you to lay a road that will allow the carriage to run at full speed. First, the route from the current palace to the kings of Demorgar, Evil, and Belvedir. You don't need it, and the route from the new capital to the kings of Domorgar, Evil and Belvedir, I want you to build something solid. "

The current palace will not be used after five years if it goes according to plan.

Well, it is true that the palace has been set up and the population is large and the land is rich, so it is not wasted because it is a fact ... It is more efficient to give priority to the new capital and focus on it.

"In particular?"

"The road from the current palace is crushed and paved. It shouldn't mean that the road is muddy and unusable. Sometimes I want to lay a road that is equal to or better than that. "

"I see ... how about this?"

Ismare shows the road design on paper.

Dig deep into the ground, paving the bottom layer with gravel and the second layer with a mixture of clayey soil and gravel.

The third layer is filled with a stone that is larger than the fist in a loose bow shape.

Then, lay a square stone cut out so that the surface is in contact with the top layer.

The bow shape is to prevent water from collecting when it rains.

"That is the state-of-the-art road structure in Greece. The important points of Clarice and Alto are like this. I think that if it is completed, it will be more than Lezad."

"Can we do it with our technology?"

"... Perhaps it's not possible? It shouldn't be that difficult. I'm worried about the stones laid on the top layer ... but I think it'll work."

Hey, isn't it good? It seems that our technology is not so inferior.

Well, if you think about it, the palaces and houses around the capital are well made.

In the countryside, pit dwellings are common, but they are handmade by ordinary people who can't spend money on their houses.

"I want to add something"

"What more than this?"

"Please set up a drain on the side of the road. I also want to make a sidewalk. If the carriage runs the same way as the people, the carriages won't fly."

People and cars must be properly separated. An unfortunate accident occurs.

I also need to secure enough space.

The path of the carriage is more than 4 meters. The sidewalk should be at least 3 meters left and right. Total 10 meters.

It depends on the traffic.

At least this is the minimum standard for major roads.

"How many people do you need?"

"How long should I lay?"

"I want the crushed stone pavement to be completed quickly in one year. I want the cobblestone pavement within four years."

Is it a bit demanding?

If my calculations are correct, I think both will be about one hundred kilometer long.

"It's like a thousand ..."

"Okay, let's mobilize a thousand more."

In other words, the total number of people maintained by Japan is 4,000.

1.6% of the population. It's a bit unpleasant, but what can we do if we consider the tax revenue growth?

"Once we receive a report on the geological survey, we will rework it and submit it formally."

"Oh, I'll be grateful. I'll take care of all the land and all that fuss. You only have control over the river and land in front of you."

While Ismail and Almus were discussing, at the order of Almus, Tetra and Nikolaos were working on surveying.

Investigate the geology of the planned capital construction site, and examine the flow rate, flow velocity and shape of the river.

All are indispensable for flood control.

Summarize and organize the stories of the local residents.

It's a tedious task.

The two work silently.

"Tetra-sama, I'm actually interested in your magic. Can you design it too?"

"It's theoretically possible, because it's just drawing lines, but it may be difficult for people who can't use magic."

While saying so, Tetra gives Nikolaos a brief explanation of the theory of magic.

Nikolaos tilted his head.

"What is zero?"

"Nothing"

"Do you put a number on nothing? Isn't it funny?"

Nikolaos frowned.

"It would be more convenient"

Nikolaos looks a little dissatisfied. I can't accept zero.

"By the way, what was that strange tool?"

Nikolaos points to the tool Tetra holds in her right hand.

"The abacus. Almus recently made it.

"Hey ..."

Nikolaos looks at the handed abacus with interest.

"How to use ..."

Nikolaos uses an abacus while Tetra teaches how to use it.

"Oh! This is amazing ..."

Nikolaos felt the world spread a little.

"After all, mathematics is good."

"I understand! Math is wonderful, isn't it?"

The two meet for a while with the magnificence of mathematics.

However, suddenly the cloud going to talk becomes suspicious.

"Mathematics can represent any number. It's wonderful."

"It's impossible. There are irrational numbers."

"Irrational number?"

"Square root of two, cannot be expressed by rational numbers."

Slightly suspicious air flows between Nikolaos and Tetra.

"No, I can show it."

"I can't express"

Tetra first explains the three-square theorem, then writes the explanation of the square root of two on the ground and explains it carefully.

Then he explained that the square root of two was irrational in contradiction.

"Well, I see ... I thought numbers were a collection of points ... but, yes, is this possible?"

"Numbers are a concept that people have created on their own. Therefore, there is no way to do it.

They leave for a while and show off their knowledge.

Tetra is a study of mathematics, physics and magic.

Nikolaos is about his specialty of astronomy and philosophy.

"What do you think is the root of everything? Is it still a number?"

"... I don't know. I think there are blueprints like mathematical formulas, but they can't be represented by numbers. Perhaps another.

"There is a thing called an atom. This world is made of small invisible grains. But what do you think these grains are made of?"

The two begin a barren discussion of a problem that could not be solved, perhaps for thousands of years.

The people around me leave work and look at the two people who talk in vain with white eyes.

What are you talking about, these guys.

"Do you know I'm chanting the ground motion theory? What do you think?"

"I normally think that the theory of heaven is correct. The theory of heaven is correct from an observational point. Even though mathematical formulas require complicated calculations, I think they can be expressed sufficiently.

Tetra breaks the word once.

"In the end, you can't tell without observation. Because neither has solid evidence that the Earth is a sphere, it's barren."

It doesn't make any sense if you can't prove it in any discussion.

If you say waste, it's up to that.

"Is that so……"

Nikolaos draws with a dissatisfied expression.

Nikolaos, who has a reputation for not reading the air, is refraining from Tetra, the queen.

Tetra has proposed to end the indisputable struggle, but hesitated to insist on opposing it.

"It's time to get back to work. Almus is angry."

"Yes, let's finish the survey soon."

The two have finally moved to work.

"First of all, the capital must be constructed. For that purpose, flood control is necessary. In addition, if irrigation facilities are enhanced, it will be two birds with one stone. When flood control around the new city is over, we must first round up and construct roads ..."

Roads are important in both economic and military terms.

With a well-maintained road, merchants will be more active and the army can move faster.

It depends on the location, but it must be given priority over flood control.

Financial resources are sufficient.

The problem is still human resources.

Because the territory has increased several times, it cannot be processed properly.

At present, land inspections and tax collections are limited to the former territories and the land around the palace. It's not very easy to cover the whole area under direct control.

Providing education with preferential treatment for orphans cannot be continued for such a long time.

The feeling of guilty for abandoning a child is reduced.

It's hard to be abandoned a little poorly because of the consciousness that the nation will raise them anyway.

It is necessary to introduce a system such as a ceremony, but ...

Because it eventually broke. I don't want to ask my country's bureaucracy for poetry talent.

In addition, in order to make the most of the difficult exams, it is necessary to prepare enough teaching materials and teachers. In other words, only rich people and powerful people can become bureaucrats.

There is no point in having a bureaucracy.

Concentrating power only on bureaucrats will result in a historical dance.

The bureaucracy is bloated because too much power is concentrated on kings and emperors.

After all, even if the power is concentrated, politics cannot be done unless the king or emperor is excellent.

So politics is completely bureaucratic.

That would increase the popularity of bureaucrats and increase the competitiveness of exams, but the problem would be too high.

Poetry cannot be selected unless it is made difficult to pass without memorizing the poems.

The end result is that the exam is far from bureaucratic.

In other words, centralization is good, but power should not be concentrated on me.

That's why we cannot abandon the existence of the royal family.

What should I do?

Well, if you think about the exams in the long run, you have to procure human resources as soon as possible.

It's not just bureaucrats that matter.

For example, a field commander who can direct construction. There are few such people.

There is a top class, but no middle class.

"Oh, the problem is gone."

I want to pretend not to look.

"King"

I was called out suddenly.

Looking forward, Yulia and Tetra were there.

"When are you guys?"

"What are you saying, you didn't allow the room?"

"Too much thought"

They sharpened their lips.

Bad, bad.

"What happened?"

"Actually, there is one case that we want to resolve human resources as soon as possible."

Julia and Tetra thrust me at the paper.

There ...

"I would like to propose a bill on crackdown on false magicians and control of magicians throughout the country.

They smiled.
