The Returned Sword King Decided to Become a Tyrant Episode 33
Lotus Blooming in Regret (3)
“Are you saying you are going to build a wall?”
Roder looked at the defensive wall being built and asked in absurdity at my words.
There is a distinct difference between a measure to temporarily deter an enemy and a wall to defend against an invasion.
Even the scale was the same.
And that was a fact that the dwarves who were building the defensive wall also knew well.
“Building something requires a design. Unfortunately, our ancestors who knew how to build walls have already returned to the bosom of the earth.”
Surtr argued that it was impossible, citing the loss of construction technology.
Because they had lived underground for so long, there was no need to build huge walls.
If you were just stacking bricks, you might understand, but you knew nothing about building a wall.
But I just nodded my head at his words.
“The wall must be built.”
Even if the attacks of large monsters were put aside, this land would eventually have to face the conflict with the Federation Empire head-on.
Even though the future is changing at this very moment because of my actions, there was no way the Federal Empire’s dirty desires would change.
If not now, while they were at war with the barbarians, there would be no opportunity to prepare.
“And this land is where you will live. If you have to depend on others for even the bare minimum of safety, are you any different from a slave?”
“… … .”
“This is the minimum duty you must fulfill to avoid living as slaves.”
My cold gaze turned to the Knights of the Sun.
“The Sun Knights will divide their personnel into a border team and a search team. The search team will immediately take the lead in subduing the monsters.”
“insect!”
After saying that, I walked towards the makeshift shelter.
Surtr and George followed behind me.
“Building a wall wouldn’t be that simple.”
“Yes. It’s embarrassing for us dwarves to say this, but it lacks everything. Not just its own weight, but even the structural mechanics to withstand magical attacks. It’s close to impossible… … .”
Towering-
I stopped walking at those words.
“Ouch!”
George, who had not been able to secure enough distance, bumped into my back and fell on his butt, but my gaze was fixed on Surd, who was acting passively.
“Are you guys born with a hammer in your hand?”
“… … .”
“If you think it’s impossible, it’s because you don’t have the determination to do it right now.”
That’s a lame excuse.
If your life is at stake and there is no one to help you.
Will it be possible to maintain the same passive attitude as now even then?
Before the return. Just like when the clan was captured by the barbarians and forced to build a wall… … .
“I have no intention of asking you to do the impossible.”
One of the plans I’ve been thinking about since I returned.
It’s time to show the answer.
I turned around and started walking again.
“Follow me.”

“This, this is… … !”
As an unidentified liquid was sprayed onto the ashen dough, the dough, which was about to lose its shape and collapse, quickly hardened.
Surtr, who had been standing there blankly, approached the hardened dough with an expression of disbelief as he saw the sight of each and every substance combined without losing its solidity.
“Steel? No, it’s softer than that… … .”
Likewise, George, who was kneading the hardened dough next to him, pushed up his glasses and said.
“… … It’s much harder than normal rocks.”
Its appearance resembled that of a material to be used in construction.
But that wasn’t the end.
“The world keeps getting stronger!”
If it had previously been stronger than a rock, it has now become even stronger after some time has passed, and has changed to the strength of iron.
The inside of the dough has completely hardened.
Surtr, who was astonished at the bricks that were created in an instant, hurriedly looked towards me.
“Oh, what the hell is this? What did you do… … .”
“I ground the stones nearby, mixed them with water, and added clay. By adding a magical agent to it, I activated its strength.”
“What is that… … .”
Looking closely, the gray paste was definitely the rocks that formed the walls of the mine.
So does that mean that they really made this with just the rocks that were overflowing on the plain?
“What you are talking about is not the recipe for Caymentum?!”
“Oh. You already knew?”
So you’re a dwarf after all?
After all, if they were blacksmith elves who had lived for hundreds of years, they should have known about the already obsolete method of Caymentum.
Of course, George had no way of knowing this.
“Caimen… … Tomb? What the hell is that?”
“It’s a construction technique that was popular hundreds of years ago. It refers to grinding down volcanic ash and using it as building material. It’s strong as is, but if you use a reagent like before, it becomes even stronger.”
“That’s correct.”

It was a material that was commonly found anywhere on the continent, and the recipe for the reagent was simple, so at one time it was used in most buildings.
The rocks in this area also happen to have that characteristic.
But the guy just thumped his chest as if he was frustrated, watching me shrug my shoulders.
“One, this is not Kaimentum! I have never seen Kaimentum of this intensity!”
“okay?”
“In particular, things made with that method have almost no resistance to mana. That’s why, from the time magic began to develop, they became inferior to ordinary stone. But this… … .”
That face gradually began to come to mind.
The biggest reason for the destruction of Caymentum was the development of magic that could interfere with the mana of objects.
Since it has no magic resistance, the structure will immediately collapse with even simple magic.
No matter how cheap it was, it was more expensive than other materials, and there was no one who would use building materials that were easily destroyed by magic.
George’s brow furrowed.
“Then isn’t there really a need for a wall that can’t block magic?”
“No, this is different.”
Surtr interrupted with a flushed face, put down the bricks, and grabbed the pickaxe on his back with both hands.
And then he looked at the bricks and took a deep breath.
Bang!
He just brought the pickaxe down.
Surprisingly, the bricks were only slightly scratched on the outside and were not broken or chipped.
Surtr continued to breathe heavily.
“I don’t know what worked, but each ingredient is connected more tightly than the Kaimentum. To this extent… … there should be at least a small amount of magic resistance.”
“Good job. It wasn’t a perfect answer though.”
I reached out and picked up the brick that had fallen on the floor.
And the mana accumulated in the magic seal was released in an instant.
Just like the one used in the land of the barbarians.
Flash-!
bang!!
The right arm covered by the coat glowed, and a loud noise was heard, creating waves that everyone present could feel.
However, the bricks that were directly affected by the waves still maintained their original state.
A magical power that can only be used by those who have passed the first threshold of synchronization.
Even though it was a technique that could scatter all surrounding mana using accumulated mana.
“This is… … !”
“As you can see, this guy’s magic resistance is far beyond that of a magic armor.”
The alloys used to make knights’ armor are a suitable mix of metals with high magic resistance.
In fact, it was no different from saying that magic below high-level was completely protected.
If true, this would be a discovery of the century that would overturn all conventional wisdom.
“How on earth!”
“We mixed the byproducts from refining Mithril here into the existing materials. Although it is dregs, it is mud that contains a lot of Mithril.”
At those words, the guy bowed his head deeply as if thinking about something.
“Certainly… … If that happens, the dough will harden under the influence of the mithril component… … and since it doesn’t use any reagents to maintain its shape, it won’t be vulnerable to mana interference… … .”
“I see you understand now.”
“Ha, so what’s more, Mithril itself has the advantage over magical attacks!”
Surtr, who realized the identity of the brick, could not hide his astonishment.
“This is… … ridiculous… … .”
The biggest problem in building the wall was finding rocks of the right size.
To do this, it usually started with the process of obtaining stones from a quarry, and then usually had to go through cumbersome processes such as cutting the rock.
But in this way, it was different.
“That, that’s right… … ! Just grind the stones from the mine… … and put them in a mold and shape them… … .”
“That means you can get a building material that is stronger than anything else, in any shape you want.”
“This is impossible! A method that only highlights the advantages of Caymentum!”
And it’s easier and faster than ever.
Since the debris from the Mithril mine had to be moved above ground anyway, it would not be an exaggeration to say that all the useless processes that took place in the quarry were essentially skipped over.
This also has the double benefit of recycling waste that would otherwise be discarded.
Surtr picked up a brick and started to make a fuss.
“If we just had this, we could build walls! We wouldn’t have to worry about weight or magical defense!”
“Are you confident that you can build an impenetrable wall at this level?”
“Of course! If we combine it with the know-how of our dwarves, it is not impossible to complete the wall within two years!”
The considerations that go into building a conventional wall were now out of the question.
Perhaps a strange wall could be born that focuses on more than just blocking enemies.
From now on, it was literally the realm of art.
“That’s fortunate.”
I muttered like that and recalled the events before my regression.
This technology, which utilizes mithril mines, was an architectural technology discovered by the Federation Empire.
They have been using this to strengthen the walls and build various structures, etc., in an effort to make the empire richer.
Of course, it was natural that raw materials from the Galderd Plains were used there.
“I really hope you leave this construction to our clan. I’ve always wanted to try something like this.”
I nodded to the guy’s confirmation.
“If you want, I can send some handymen to help with the construction. It would be better to have their cooperation so that I can devote more time to it.”
“Oh! You’re even being so considerate?”
“You guys didn’t come here to build a wall.”
This land is Esteban’s after all.
They were not slaves, but ‘collaborators’ with free will.
“Securing your own safety is your duty as a living being on this earth. But how you spend that time is entirely up to you.”
“Whether it’s building walls, developing mines, or even making weapons, it’s our freedom… … .”
“okay.”
I said, looking at the dwarves coming and going through the mine entrance.
“Follow me. I will now explain the wall that will be built.”
* * *
I took out a piece of paper with a rough sketch of the castle wall drawn on it and placed it on the table.
George and Surtr peered out to inspect it, then painted over the detailed design so they could see it.
“The wall will be built as a triple structure, separated into an outer wall and an inner wall.”
A wide and deep moat. Behind it, a low wall stood in front to keep out the men, and an 8-meter high inner wall was built to protect it.
Finally, the magnificent 15-meter high outer wall that encompasses the entire battlefield.
The structure was constructed in such a way that any enemy facing this wall would inevitably take massive damage as they reached the outer wall.
“… … Such a sturdy structure.”
Surtr stroked his long beard.
The rear, which was relatively weakly defended, was blocked by a natural mountain range, and as the slope gradually became steeper, it would take a huge amount of force to break through it from the front.
If this design had been followed, it would not have been strange to call it a ‘natural fortress’.
