"Heel husband, the edge is over!

Haines of Kobolt saluted him as he rushed over to me.

Edged is where to build the walls.

On top of the landfill, a line is drawn with green paint made from the leaves of the world tree, on which a wall is built.

And useful for this kind of major construction is the function of the [Cave King] offal workshop function (workshop).

This is the ability to process a variety of things from the ore in the inventory that I own in [Cave King].

For example, just rocks can be stoned, crushed and sanded.

Stone allows you to freely specify the shape and size, and sand can be made into whatever color you want by crushing rocks.

Fine things can be made by demons, but when building these big architectures, it would be quicker and safer to use this ability of mine.

"It's been a long time since you've used the workshop functionality... then, let's go"

I made sure no one was inside the green line and turned my right hand there.

Then the square stone jumps out of there with the cum.

The stone buried inside the green line, like a puzzle.

I don't know where in the workshop, I process the rock from the inventory into stone, and this is how I release it.

"Whenever I look at it, it looks amazing... it looks like it's out of my hands"

Haines looked at my hand and said so.

"Really? From what I can tell, it feels dumb..."

It's like a cloud showing tricks in Wang Du... Plus, if you want to show the flag with flowers like them, it's still interesting, but it's just stone, so it's nothing plain.

I would like to apply even elaborate decorations like sculptors, but I don't have a painting heart.

Besides, this is only a castle wall, so let's just say we make it serious.

"... All right, now we're done with the first step"

When I said, Haines answered.

"Copy that. Then I'll mortar it!

"Oh, I'm sorry... I wish I could make mortar too..."

Mortar is a type of building material used to clear gaps when building up these stones.

Calcareous volcanic ash is mixed with fine cement and water, which is muddy at first, but gradually hardens like a rock.

It's an essential ingredient in Wang Du's architecture, but it won't stick unless it's properly formulated.

Naturally, I don't know anything about architecture.

All the demons here also had many people living in the woods, so it was only about wooden architecture, even if they knew it.

So what makes mortar wasn't on this island.

In the meantime, I asked Mappa to make a mortar. He made me something similar, on trial and error, even though he had a difficult face at first.

I look at what the usual mappa would look like, but he looked a little less confident when he showed me the mortar.

And even now, he looks anxious when he sees the mortar in the barrel carried by the demons.

Are you not very confident that you can do it?

For once, what you showed me was solidified.

Mappa makes the demon carrying the barrel stop by hand when he waits, opening the barrel lid.

And I licked a barrel of mortar and nodded quietly.

"No, you lick it and you know...?

Nevertheless, to see Mappa's convinced face, I guess that means it's okay for now.

The demons will carry the barrels one after the other, and will prepare the tools known as the jaws.

They serve to mortar over the stones I've lined up.

Adhesion to stone piles on top, again to fill the gap between stones.

"I'm going to apply it... I thought it would take about an hour"

Haines reported that to me.

"An hour or so...... in the meantime I guess I'll go back to mining"

But it'll take more than enough trolleys to get to the current mining site where we're digging toward the control device.

Trolley takes longer to get up than to get down, so you can think of a little more time to get home.

If so, at most thirty minutes can be mined......

Besides, it's only the first step, so I have to come and go every time I continue to do the same work with the second and third steps.

Not that it's a hassle... but it's inefficient.

Because of this, I probably should have machined the stone to a large extent and almost walled the rock itself.

And then I wish this mortar could be made even in my workshop function...

With that in mind, I put a little mortar on my finger.

I wonder if I can collect this...

"... ah"

With that in mind, my finger mortar instantly disappeared.

Were you able to collect them because they use rocks and minerals?

And

"There are more items that can be created in the workshop function. Cement, mortar and concrete can now be created:

... Cement is a powder of mortar ingredients. But concrete? What the hell?

"Concrete… it is a type of building material, mainly used in architecture."

Is it a type of building material? I might be able to try everything in architecture.

... Well, I'm not sure, but it means that mortars can be made at any rate.

Then you need water to make a mortar...

Water is not in my inventory.

Besides, can't water be recognized as minerals or recovered?

I wish I could extract water by whatever means...

Can I collect the mortar that's here now and paint it?

"All right... guys, let me handle this."

I retrieved the mortar in the barrel that the demons had brought to my inventory.

Haines saw it and asked.

"Heel husband, what?

"I can paint this all at once. Look at me."

That's what I said, I pointed my right hand at the stone.

And ordering the release of the mortar...

From my right hand, the grey white liquid was released with momentum.

"Whoa!? That's a lot of momentum..."

I'm going down on the lined stone as I regulate it.

This... sounds like a lot to use.

When I fought Leviathan before, I unleashed a rock and attacked him, but this seems pretty usable too.

It's hanging around, and as it solidifies, if another giant enemy like Leviathan strikes, it could be a sight to behold.

And when he had finished spreading it, he lined it with new stones.

Two or three steps and repeat that...

"Oh, I didn't expect to make it this far in just a few minutes!!

Haines and the demons raised their voices when they saw the walls piled up in front of them.

A wall four to five times the length of my back. Compared to the walls of the king's capital, it's a fine thing.

All you have to do is put up a wall that protects the corridor section above the walls, called the chest wall. Ah...

Try to climb up the walls that Mappa has created.

"Mappa, it's not hardened yet! Danger...... whoa"

I was yellow bug in front of me... I felt like I could see a bee so I tried to pay with my hands.

But it's no good paying off.

I immediately looked around. To find a bee.

"... to this island to the bees? Huh?"

Behind the mappa, a giant bee like a human could be seen standing with a needle.
