Seiun wo Kakeru

The sound of cancun and hammer slamming sounds.

Iron metal sounds continued to echo everywhere in the blacksmith's heated space.

Sounds softly, no longer audible.

If you don't hear this sound, Pietro doesn't feel comfortable somewhere.

It was no longer a daily landscape.

The blacksmith is somewhat dim.

The lighting windows are small and the flames of patch and charcoal illuminate the surroundings blurred.

It keeps darkness in order to identify changes in the color of the metal.

Higher temperatures make it red and white.

If it falls, it becomes orange.

Forecast the iron temperature with that subtle change of colour.

If the temperature is too high, the carbon in the iron will escape and the iron will become soft.

My parent, Age, is the one holding the gavel and giving instructions.

And it was his disciples Pietro and Dante who had the Great Hammer.

"Next here."

"Yes!"

"Ugh!"

"Extend it to Koch more! Come on!"

The instructions from Age are brief and quick and demanding.

It's because iron cools down in slow work.

Pietro could not be caught off guard for a moment because he would not throw a tight word, but would get accurate allegations every time.

Shake up the hammer, turn on the recoil and shake it down.

Tap the hammer and timing it to where it was directed, rhythmically not to bump into Dante.

With Cancún, and Cancún.

Waving the hammer is very physical.

Ugh, my breath rises, my sweat blows out.

Stirred by heat, the sweat dries over time and gets wet again with the next sweat.

Drink more than three litres of water a day. Lick salt too for sweat.

I apprenticed under Age, and a long time went by.

In the beginning, it was so exhausting that at night it became too much and the meal didn't go through my throat.

These days, my body has been able to rise and swing well using rhythm and recoil again.

After finishing the work to a good point, Age spoke to Pietro.

The harsh expression immediately lurks the ringing and has a soft grin.

"You're used to Pietro a lot. You look like you're waving a hammer."

"Thank you"

"Are you getting used to making your own?

"Right...... Not yet, but the more I do, the more I realize where to go."

"It's a good thing. If I could afford more charcoal and iron, I could practice even more, but all this."

Age turns a slight gaze.

The amount of iron and charcoal piled into the blacksmith is not that great.

"I want to practice more too."

"That's right. Speaking of which, it seems that there will be more trees in the village, so maybe there will be more we can do."

"You did it!

Nature and grin spilled over Age's remarks.

The blacksmith can only gain experience by hitting himself.

But iron and charcoal are invaluable.

The steel furnace that Age continues to repair was fairly high-performance, but the yield still left much room for improvement.

I usually use the material as a product and have it divided into practice from time to time.

This became the basic flow as a disciple.

If you can't beat it yourself, you just have to watch people beat it.

It's called foresight.

Where is the decision to instruct where to beat Age, and what instructions will fly if the iron temperature is about?

Pietro had enough room these days to care so much about that.

Pietro had doubts these days.

Because it seemed like Age was sorting the iron chunks that he refined.

Now Pietro was comparing the iron sleeping in the warehouse.

Refined chunks of steel roll and pile up.

It is classified as soft and steel so that it is easy to use when using it.

The distinction between soft and steel can also be made by Pietro.

You can grasp some sensory difference between the softness or weight of the sound when you tap it.

But Age's classification is even more nuanced.

It's not just the separation of soft iron and steel, such as ground gold and blade gold.

Even in steel, it looked like Pietro, as he classified it even more finely.

Is there an indescribable subtle difference among the same steels?

Pietro took it and no matter how much he looked at it, he didn't know the difference between iron.

One customer gets this iron, and one particular customer orders this iron.

It's like they're doing that sort of usage.

"Pietro......? What's the matter, at this hour?"

"Oh, parent!? Shh, I'm sorry. Just wondering."

"I don't even think I'd steal anything else, so I don't mind seeing it. If there's no obstacle, I'll ask, okay?

"Ugh...... Well, it looks like my parents are picking iron."

"Whoa, did you notice that there? Let's do it. That's the best apprentice I've ever had."

"So hehe... Oh, not so much."

Praised Pietro's face nibbles naturally.

Even if I want to squeeze my face tight, my mouth angle goes up on its own.

I trust Age more than anyone.

Strength is certain, not the type of person to flatter.

That's why I was so happy to be praised by that age.

but I realized it wasn't like that.

I felt like I was being told the story well.

"You're not!

"All right, all right. You don't have to keep your face close like that. I'll teach you."

Age pointed to the corner of the warehouse, showing both hands up and surrendering losing to Pietro's temper.

There is iron arranged by Age as a sample or for comparison.

Age does something to make a sample.

One tool, one material, can always be compared, so that the disciples can compare.

Pietro once heard me squeal because I don't have the material.

"Even if we refine iron ore in the same way, just a little bit at a time, the ingredients are different."

"I knew...... So we can sort it out, right?

"Good iron is a difference. I know the order. If you don't use it from the owner, it won't be worth it, will it?

"Even if it's one thing, some people use it in a nasty way."

Maintenance is completely different from a forceful, beating user and a user who understands the blade well and uses it well.

It takes a lot of work to make one, which is why I want you to treat it with care.

Age's explanation began.

The difference between soft iron and steel is basically determined by the amount of carbon component.

If there is less carbon, it is soft, and if there is more, it is stiff.

Very much makes it very hard, but very brittle at the same time.

If the blade is missing, the cut flavor will be dull, so it is not good if it is hard.

"It's hard to grind if you're missing it."

"If it breaks, it's the source of the injury, and I knew no evil iron would work."

"Even with the same amount of carbon, other metal components can change the flavor, length, and brittleness. I wonder if phosphorus and sulfur are particularly troublesome."

He said the most troublesome thing is sulphur.

Even soft iron with low carbon concentrations tends to chip, Age was distorted in the face.

"This is iron with a lot of sulfur components. I'm gonna slap you. Look closely."

"Wow, that's lame. I mean, there's a lot of holes in iron, too."

When I slapped the iron for the sample with cancer, it actually seemed like it would be polarizing and missing.

When I wondered if it was so brittle, I found it very blade and unusable.

Refining with coal has a high sulphur content, so it used to be difficult to obtain fine iron from smelting iron.

The Ages now make iron out of charcoal.

The temperature is difficult to raise, but it is easy to make fine iron.

The amount of wood used for that division will increase tremendously, and half of the manufacturing costs will be spent on trees, not iron.

Age was foolish to say that if he didn't sell it as a luxury item with a high replacement ratio, it would be very unproductive.

Pietro listened firmly to everything, even if it was incomprehensible by the way to what Age was saying.

Someday, somewhere, it might help.

Especially if Pietro is independent.

If there's anything about Age.

"Manganese, molybdenum, nickel, silicon, tungsten, chromium, copper, cobalt, titanium… these areas are good ingredients for rust resistance, toughness, and iron"

"Hey, wait a minute, please. I'd like an explanation now."

"Oh, I'm sorry. You've spoken on your own again. Bad habit."

It was hard to chew Age's description, which gets a little quicker as soon as he starts talking.

Age is very smart and has an excellent memory from Pietro.

He was a strange person wondering where the hell he got this knowledge.

Even though he usually has a small mouth count, talking explosively as soon as he starts talking is also a characteristic of Age.

"These substances are now being tested and misused so that they can be successfully adjusted during refining."

"Well, how do I know that?

Pietro was much in doubt.

Now I know what Age calls good ingredients.

But it doesn't make sense if you don't know where the hell to source it and adjust it.

But such Pietro's concern was already the path Age had taken.

A gentle nod told me the solution.

"I'm asking Jean, the pedestrian, to make a lot of deals. They're gathering all kinds of stones and metals from all over the island."

"That's... not a crap, you know."

"No, I'm not! Totally rude. I'm not so thoughtless."

"Excuse me. I thought you had an unusual hobby."

Age says angrily, but Pietro knows.

For my wife Tania, I would spare no effort for very precious honey, fruit, and cloth.

Must be processing gems and handing them over to Tania as well as making iron.

So I wonder, Pietro's gaze, just now, has become a snug one.

"All you have to do... this is a bet, but you have to mix and melt a lot of things and consider the difference"

"It's a distraction."

"Sort of. There seems to have been a profession of alchemist to make iron refining a little more efficient."

"Well, do you have a job like that?

"Well, that's not the only research alchemist. He's been doing a lot of research on medicine and astronomy."

"It's like being an Age parent."

"What!? That's not... it's not...? Wow, we're more or less together on what we're doing. Oh, my God."

Apparently Age, who develops something suspicious every day and startles the whole village, wasn't aware of it.

Oh, my God, I repeat, I finally held my head.

Even though I still couldn't tell you I understood iron, it was a pietro that I just found out a little bit about iron.
