"Oh, Ad, did I wake you up? I'm sorry."
No, I'm always early in the morning.
Krull and Marle seemed to still be sleeping.

Adriana washes her face in the well in the earthen floor and receives from F-002 the materials for magical engineering that she had brought with her last night.
Maybe you can do it. Here, like this: ......"
Adriana was absorbed in her work while Bice was preparing the breakfast.

"Now, please give me this."
And when she handed the finished magic tool to F-002, Bice called out to her.
"Ado, breakfast is ready!

Krull and Maruru had just woken up, especially Krull who was still sleepily rubbing his eye lids.
"Bon appétit!"

Breakfast was barley porridge. Again, salt with herbs is used, and it is quite tasty.
Bon appétit!

Krull and Marle followed Adriana's example and began to eat.
The porridge tasted even better when sprinkled with herbed salt, and Adriana had two more bowls of porridge.
"Thank you very much for the food."

Adriana says after the meal, a greeting she has learned in her life with Shuki.
Krull and Marulu say the same after their meal.

I don't know if it will take root in Adriana's life, nor do I want it to, but I am sure that it has created a stir in the local customs.

"Ado, what are you doing today?"
Krull asks Adriana after the meal.

"Do you want to continue where we left off yesterday?"
Marle asks if they are going to search for stones again today.
"No, today we are going to visit our master again ...... Phytos."

Yesterday, I had a small amount of nickel and chrome, so I thought I could make a prototype.
5 grams of chrome, 2 grams of nickel. If the fork weighs 25 grams, I should be able to make one piece of what is called 18-8 stainless steel, which is 18 percent chromium and 8 percent nickel. 8 stainless steel with 18 percent chromium and 8 percent nickel, I should be able to make one fork.
In the meantime, we arrived at the blacksmith Phytos' workshop.

Smoke was already rising from the workshop and I could see that Phytos had lit the furnace and started to work.
"Grandpa!
Phytos, who was about to start work with a block of iron in his hand, turned around.

"Oh, Krull! ...... and Marle, and little girl. What are you doing today? I was about to make a prototype fork out of iron.
First the iron is heated, then beaten flat and stretched, and shaped with a hammer and file, which seems to be the usual way for a blacksmith to work.
"Yes, that's it, but I've got a metal that becomes rust-resistant when mixed with iron, so I've brought it here."

"What? You have such a thing?
Fightos is surprised. Krull and Maruru are also surprised, but they are not experts, so they only think <>.
But Phytos is surprised,

"Well, if such iron could be made, it would be a revolution!
he says excitedly.
But Adriana shakes her head apologetically.

Fightos' shoulders slumped in disappointment. But Krull saw it,
"Grandpa, the three of us looked for it hard yesterday!
I apologized in a hurry.

"Oh, Krull, we didn't mean it like that. I just thought it would be great if we could make a lot of that kind of iron.
"First, let's make a prototype. Let's make a prototype and then we'll see what we can do about mass production.
Adriana interrupts.

"Well, that's a good idea.
Phytos said as he lowered the piece of steel in his hand to the floor.

"So, how do I mix it with iron?"
Iron is an elemental name for steel. In reality, pure iron is not available on the market, but is an alloy of carbon and

Cast iron for casting (pig iron) is called iron, but it contains 2 to 6.7 percent carbon and is in a state before being refined into steel (hence pig iron is called gold). （Pig iron is therefore called "pig iron first" in Japanese.)
Pig iron melts at relatively low temperatures (still around 1200 degrees Celsius) and has good fluidity, so it is used for pouring into molds.
Also, <

"Well, may I use some of this iron?"
Adriana asked, examining a piece of iron that Phytos had just prepared.
"Yes, of course. That's what I was planning to do.

Phytos, being a good cook, seemed to think that the steel should not be too hard. That's what I'm talking about.
"Well, let's see... ......<

"Well, Mr. Fightos, could you try to make this into a rough fork shape?"

Adriana handed a curious Phytos a 25 gram chunk of 18-8 stainless steel.
"Oh, thank you, sweetheart. Let's give it a try."
Phytos placed the block in the furnace and began to work the bellows.

The fire raged, and the small lump turned red in no time.
He took it out with a pair of iron scissors, placed it on the anvil, and began to pound it with a large hammer.
"Hm......?"

Fightos tilted his head while tapping.
"What do you think?"
Adriana asks.

"It feels a little sticky, maybe.
He says nonchalantly. After two reheats, Phytos has roughly formed the fork with just a hammer.
"Now I just need to cut out the blade with a hammer.

He got out a smaller blade and put it on the prototype and started cutting .......
"What the hell is this?
I felt an unexpected resistance, and I couldn't help but shout out.

Stainless steel is very sticky, making it difficult to perform cutting-type processing.
Adriana had seen this kind of work several times with Shuki, so she had a pretty good idea of how Phytos would feel about it.
"It's not hard, but it's hard to cut ......."

"Yes, that's one of the advantages and disadvantages of stainless steel.
"Yes, that's both an advantage and a disadvantage of stainless steel. It's good that it's strong, but it's hard to work with.
"It's also hard to sharpen.

Since it is difficult to sharpen with an ordinary whetstone, ceramic and diamond whetstones are often used in modern Japan.
"I see. ...... It's true, it's not suitable for making many pieces."
Phytos looks disappointed.
