Chapter 195. (2)
“Once upon a time, long ago, when the quality of treated water was relatively good, and the biological oxygen demand (BOD) was less than 1000 coliforms (100mL MPN) and the maximum turbidity was less than 10 degrees, the slow filtration method was used. It is said to have been adopted.”
“…for a moment.”
“Raw water is a treatment method aimed at removing a small amount of suspended matter and trace amounts of organic substances in raw water from dam water lake water where eutrophication of groundwater has not progressed, river water where contamination has not progressed, etc. The slow filtration method filters raw water slowly through a relatively thin sand layer….”
“that…only….”
“By this action, trace amounts of ammonia, nitrogen, manganese, bacteria, and odorous substances are also removed from suspended solids. Settling basins are not required when the annual maximum turbidity is less than 10 degrees, normal settling basins are installed at the annual maximum turbidity of 10 to 30 degrees, and chemical treatment settling basins are installed at the annual maximum turbidity of 30 degrees or more.”
“…Drurling pyuyuu.”
Serazade’s head tilted back.
Soon, a loud snoring sound rang out.
A satisfied smile bloomed on Lloyd’s lips.
‘good.’
Judging by Serazade’s sound sleep, it seems that he lost his strength during the day.
It must have been thanks to Xaviel’s diligent swordsmanship.
He turned to Xaviel, who was standing beside him.
He conveyed his meaning with gestures.
“It’s done. Open your hearing.”
Seeing his hand gesture, Xaviel reacted.
I opened the hearing that was intentionally blocked.
“Are you done?”
“uh. Are you sorry you couldn’t hear the lullaby?”
“no. at all.”
Xaviel shook his head with a hard face.
Lloyd’s smile turned mischievous.
“at all? really? really?”
“yes. Absolutely.”
“It wouldn’t be a lie. I’d love to hear a lullaby. it is not so?”
“It’s not like that.”
“Imagine. You sleep perfectly comfortably. I’m going to the land of dreams with soft lullabies in my ears. There is no pain or worry there. perfect relaxation. Complete relaxation that even exfoliates the soles of your feet. stretched out warm. Cozy. Dudungsil. Just thinking about it. kyaa Isn’t it wonderful?”
“….”
“I know that? Did you just open your eyes slightly?”
“….”
“Uh huh. Don’t open your eyes again.”
“….”
“Are you going to open your flounder eyes and stare at me now?”
“…Whoa. really.”
Xaviel let out a deep sigh.
It’s nasty.
I’m going crazy because it’s so nasty.
Thinking of it, I really want to hit at least one egg.
If it wasn’t for the young master he served, he would definitely have been.
But now there is no time for that.
Because now it’s time to go to work.
“Can we do the same as yesterday?”
“uh.”
Xaviel quickly put an end to the resentment that had been bubbling toward Lloyd for a moment.
Instead, I calmly asked about today’s tasks in a businesslike manner.
Lloyd nodded.
“There must be a place I marked during the day.”
“Should I keep the size and slope of the tunnel the same?”
“uh. I marked it as a guideline just like yesterday. Just do it.”
“All right.”
Xaviel stood up from his seat.
And took the sword.
Just like the last few days.
He put on a sturdy leather vest over a simple shirt.
I also brought a mask to protect my nose and mouth from the thick dust.
“Then come back after a little rest.”
“uh. Be careful too.”
“All right.”
Perhaps Lloyd-sama would go to the scene after a couple of hours of sleep, as usual.
So what about yourself?
Dig in the designated area until Lloyd-sama comes.
You just need to drill a hole exactly in the designated area.
Thinking so, Xaviel left the dorm.
Excavation construction for qanat construction.
I went to the site where the construction was taking place.
While moving to the site, the things I had done in this city came to mind one by one.
‘Has it been two months already?’
It has been two months since I came to this city.
For the first month, I had to stay only in the dorm.
It was his daily routine to quarrel with Serazade in the inn while Lloyd did the surveying and designing.
Fortunately, I wasn’t bored.
It was also a suitable exercise and stimulation for a higher level of swordsmanship.
In the meantime, Lloyd’s tunnel survey and qanat design were completed.
At the foot of the distant mountains to the west.
Did they say that they succeeded in designing a tunnel to connect the 36-kilometer gap from the water intake there to here in the shortest distance?
It was from that day.
‘I wonder if it was a month ago that I slept properly.’
In the second month, I hardly slept.
The reason was simple.
During the day, he had to tie her up while competing with Serazade in swordsmanship.
At night, I went out to the field and was busy digging a tunnel.
Thanks to that, it was normal to feel extreme fatigue.
Sometimes I even got dizzy.
A mana heart of tremendous density that surpasses that of an ordinary sword master.
It was the same even though he was supplementing his stamina with an astounding mental method.
But Xaviel didn’t care.
No, on the contrary, I was enjoying the situation.
Even though there was a simple way to stun Serazade and get him to rest, he didn’t.
He deliberately responded to the confrontation all day and abused himself.
‘Because I can train little by little just by overcoming extreme fatigue.’
I will no longer settle for the status of a sword master.
The level of simbeop will also be raised to a higher level.
If that’s the case, it won’t work in the usual way.
There is no such thing as mere determination.
Xaviel was acutely aware of that fact.
What if you had to transcend human limitations to reach the level of a sword master?
Now that they are aiming for the top, they have to break free from human restraints.
It must endure all adverse conditions.
We have to overcome.
Literally unanswered.
It’s like you’re challenging a place that no one has ever stepped on or reached.
It is because he is trying to move towards such a transcendental state.
Xaviel thought that such hardships and difficulties were natural.
I arrived at the scene today, determined to overcome it.
“I said we could start working from the inside. Follow me.”
We were guided by a rebel man guarding the site.
I walked through a long tunnel.
As we walked, we could find traces of Lloyd’s work during the day everywhere.
‘They’re blocking all the other passages that won’t be used as waterways in the existing tunnel, Lloyd-sama.’
Bricks and cement piled up everywhere.
Most of the originally opened passages were tightly blocked.
It was probably to prevent the water from flowing to the wrong place within the qanat to be completed.
‘I’m sure Lloyd-sama must have been working hard all day.’
What if someone you don’t know sees those bricks and cement?
He must have simply assumed that the aisle was blocked.
But Xaviel was different.
How difficult is such waterproofing?
he knew now
It was thanks to my participation in numerous projects.
That simple looking cement wall.
A simple looking brick wall.
All of that was actually the product of hard work.
It was the result of numerous engineering calculations and deliberation experiences.
The construction process was the same.
Just because the design is done right doesn’t mean the end result will be built right.
That’s why you need to pay more attention, work hard, and put your heart and soul into it.
Bubbles must work hard to collect the volcanic ash ejected by the volcanic eruption.
You have to mix it well so that the cement doesn’t crack.
The size and angle of the bricks must be precisely matched.
Are the positions and angles correct?
Is the thickness not enough?
Are there any fine gaps or holes where water leaks or moisture seeps in?
You have to take care of each one, build it up, put it on, and check it.
‘Where the hell did you learn these things, Lord Lloyd?’
In the past, I was just a young boy who only liked to go on a spree.
Where did the family learn these things so skillfully without even knowing themselves?
‘Before, I pretended to have learned knowledge at a mysterious school in my dreams.’
I suddenly remembered.
Was it the time Viscount Lacona used to play with the river?
It must have been around the time when a water supply was being built in the territory to overcome the river pollution.
I asked Lloyd.
where did you learn this
Then Lloyd said he answered like a joke.
that I dream
In his dream, he becomes a student at a strange university he has never seen before.
At that university, I was constantly learning knowledge related to construction.
Thanks to you, I can do these things.
I wish I had returned that answer.
‘Maybe it wasn’t a joke.’
At the time, I thought it was just an insincere answer to make fun of myself.
Now that I’ve come, I wonder if maybe that absurd answer was real.
“It’s out of here.”
The voice of the rebel man awakened the consciousness on this side, which was lost in thought.
Xaviel raised his head.
Before I knew it, I had arrived at the end of the tunnel.
I could see all sorts of signs engraved translucently on the rock wall there.
bluish glowing dots and lines lines and planes.
These were the construction guidelines left by Lloyd.
Next to it was a note from Lloyd.
It was a memo dictating the contents of the work.
[I’m going to sleep well while you sell this. Fighting.]
“….”
Shall we go back to the dorm and hit one?
Power entered Xaviel’s grip as he held the sword.
♣
Qanat construction continued.
Similar constructions were repeated every day.
When the sun went down, Xaviel went to work(?) to the site.
Following the construction guidelines left by Lloyd, the tunnel was dug.
Every flash of his sword fired a carefully controlled blast.
In an instant, a long hole 20 meters long was formed.
60 cm wide.
1 meter high.
It was a narrow aisle that only one person could pass through.
At first glance, it seemed too narrow.
But in fact, it was an oyster of a carefully calculated size for work efficiency and stability.
‘of course. If it’s wider than that, the risk of collapse increases dramatically.’
If the hole is too wide, the earth pressure applied to the hole increases accordingly.
This increases the chance that the oysters will not be able to withstand the weight and collapse.
So it was.
From the start, Lloyd intended to complete the project as quickly as possible.
To this end, the passage to be dug into the waterway was selected to be the most appropriate size.
There are only two criteria for size.
It must be the maximum size that can withstand the load on its own without the aid of steel support, shotcrete, rock bolts, etc., which are the support structures of the tunnel.
At the same time, the minimum space for the manpower to manage the cave after completion will be secured.
The design was based on these two criteria.
It was an oyster 60 cm wide and 1 m high.
Of course, I also ran numerous simulations.
What is the probability of collapse in each section when water has flowed inside the canal for tens or hundreds of years?
Numerous experiments were repeated with different soil rock compositions for each section.
As a result, Xaviel suffered a lot.
“Whoop whoop!”
The tunnel used as the waterway was too narrow.
Since it is only 1 meter tall, I always had to crouch down to move around.
Since it was only 60 cm wide, it became difficult to turn around or handle the sword.
However, even today, the iron-blooded knight who tried to overcome the limitations of a sword master accepted all adverse conditions as a training process without a single complaint.
Throwing Chemistry-!
Every time Xaviel’s blasts flashed, the waterway was extended.
An extended waterway connected the existing tunnels with the shortest path.
It looked like capillaries connecting the underground.
After Xaviel dug the burrow overnight, Lloyd took over the work in the morning.
“Lululu. Lalala. It’s bullshit!”
“Bell!”
Fuu-!
Gathered volcanic ash from the volcanic eruption of the bell.
The cement was thoroughly rubbed with the collected volcanic ash.
The passages were blocked off with rubbed cement and bricks.
This was to prevent the water from leaking into the wrong place.
‘Because if you don’t stop like this, it’ll be a mess. If the water seeps into the wrong place and the flow remains stagnant, it’s perfect for bacteria to multiply in large numbers.’
When such a situation occurs, all the waters of qanats are polluted.
In other words, there is a situation where the water that has been drawn is not used at all.
To prevent such a catastrophe, Lloyd sealed up all areas of the tunnel that were not to be used as waterways.
That’s how the iron-blooded knight broke through.
The noble family boy is blocking it.
Both tasks were repeated night and day.
10 days, 15 days, 1 month, 2 months.
The waterway that started near the city of Kandara eventually reached the vicinity of the water intake well at the foot of the western mountains.
“Today we will mark the end of a long construction period.”
The day before completion.
Lloyd had Xaviel and all the rebel workers gather.
I looked around at everyone at the place where the completion of the ground above the mojeong was scheduled.
“Everyone has worked really hard.”
The faces of the rebel men, including Termez, showed emotionless emotions.
It was because everyone worked together day and night covering themselves with dust.
‘of course. Without their help, the construction period would have been much longer.’
Lloyd felt gratitude to the rebel men in his heart.
Did he block the useless part of the tunnel by himself?
It wasn’t.
The rebel men moved cement and bricks together.
It was also their merit to move the excavated soil outside.
In addition, they drilled numerous vertical holes 20 meters deep at 100 meter intervals.
It was a passage to be used when descending from the ground to the qanat waterway for later management and repair.
‘He took care of all those miscellaneous tasks.’
Construction is not done alone.
Numerous workers must band together and help each other.
In the process, sometimes troubles arise and minor gains and losses are weighed, but in the end, everyone has to become one and scoop the last shovel of completion.
that’s the scene it’s construction
“So it is. I think all of us, who have been willing to cover the dust together, should enjoy the final moments of construction and construction together.”
“So, are we all shoveling together at the end of the canal?”
After Lloyd’s speech, Thermes asked a question.
At that question, Lloyd smiled faintly.
“It is not. Then it will be a big deal.”
“yes? It’s a big deal….”
“I die.”
“….”
Thermes was at a loss for an answer.
Lloyd’s smile deepened.
“I don’t know if you know, but there is only a 3-meter-high rock wall between the end of the waterway we dug and the water intake well. But the depth of that mojeong is over 30 meters from the surface. There is a lot of water in it, and the water pressure is enormous.”
“If you do, the moment you break through the rock wall and connect the waterway….”
“Yes, that’s right. The water stagnant in the well suddenly sweeps the inside of the canal with tremendous water pressure.
Lloyd scratched his neck with the blade of his hand.
“It’s just hooking up.”
It was true.
The water pressure that bursts at the moment the waterway and the mother house are connected is not at a level that humans can handle.
There is no way to avoid instant death.
So the ancient Middle Eastern workers who actually built qanats….
“Do you have any other method in mind?”
“yes.”
Lloyd nodded.
Of course, there is a method in mind.
“It only takes one person to make a sacrifice.”
Workers in the ancient Middle East did just that.
The oldest among the workers decorated the final moments of the qanat construction.
Solemnly and calmly, he struck the final pickaxe.
That’s how Suro and Mother Jeong were connected.
dead.
They were willing to make sacrifices to provide clean water to countless descendants.
“But, actually, we don’t need one of us to die.”
That, too, is a matter of course.
The ancient Middle East is the Middle East.
here it is
Therefore, there is no need to sacrifice a normal living person.
Even more so if there is someone who can calmly do such a thing without any harm.
“yes?”
Lloyd grinned and looked behind the rebel men’s shoulders.
Sensing that gaze, the rebel men turned around.
The back of everyone’s eyes.
Over the rocky mounds at the foot of the mountain.
There, a skeleton soldier with a bent neck exposed his skull.
I raised my bony hand towards everyone.
As I learned from Lloyd one day.
Instead of greeting, he drew a Korean-style finger heart.
squeaking!
It was the skeleton soldier Turtle Neck, the leader of the skeleton soldiers who came to Lloyd from the Frontera territory, over the mountains and across the desert.
