5Half nickel steel, although tough, is not so suitable for blades.
This is because the addition of nickel leaves a large amount of austenite, which reduces the hardness of the steel.
Therefore, Jin began by first separating the nickel from the remaining 5½ nickel steel ingot.
"<> Nickel".
From the remaining 1.79 tons of 5½ nickel steel about 98 kg of nickel were separated.
The resulting pure carbon steel should be enough to make 100 swords.
"Well then, Elsa, let's practice separation.
Jin invites Erza to join him. Jin began to explain to Elsa as she approached.
The trick to separation is to visualize the <> accurately. Ten 1-gram pieces weigh 10 grams. 10 grams is 10 grams. 10 grams is 1 gram, 100 grams is 100 grams. It's a repetition."
"I know what you mean."
"The key is to know how much a gram is. That's the first step.
By saying out loud what he had already memorized by feel, Jin himself understood more deeply. At the same time, he realizes that his predecessor's way of thinking is very close to modern earth science.
Not everything, of course. There are some digital ideas in some places, and some of the materials are treated down to the molecular level.
It is a little too late to say this, but it was also surprising to see how the muscles of golems and automata are so close to those of human beings that one would need to know their anatomy to make them.
(Maybe the previous generation was also a summoned person.)
(Maybe the previous generation was also a summoned person.) No one can answer such a question, though Jin does not think so.
"<>"
Jin returns his consciousness to Erza. Erza is trying very hard to use separation to create a one-gram chunk.
"You can do the separation without any problem now. Now we just need to recognize a gram.
A skilled craftsman can see a flat surface with his palm.
Magecraft masters have such a sense, but even if they don't go that far, humans are surprisingly good at measuring things with their eyes.
A woodworker can tell the thickness of a 3mm from a 4mm board without measuring it, and a skilled driver can sense a change in air pressure in a tire.
The point is that you can reach a certain level of skill through habituation. The higher the level, the closer one comes to becoming a Magecraft Meister, a magical engineer.
"<>...... How about this time?"
After more than a dozen times, Elsa's senses are getting much better.
"Yes, I think it's good enough. "Yes, I think it's good enough. Let's take out a 2.2 kg lump. Reiko, take care of the adjustment.
"Yes, father. ...... Elsa, let's do it.
Yes.
So, Reiko verifies the lumps that Elsa made by separation and fine-tunes them to a more accurate amount.
At first, the amount was too much or too little, but after 30 times, the error was getting smaller and smaller.
"Hmmm, Mister Elsa is also quite impressive, isn't she?
Gloria, who was watching the work, was impressed by the progress she had made. She, too, had never known an ordinary magecraftsman, so she did not realize how out of the ordinary this was.
Princess Rieschen is very interested in magecraft and watches intently.
Hannah, who also likes to see Jin working, watches him quietly, but she seems to have grown tired of the sight of him working endlessly on a 2.2-kilogram piece of steel.
Jin senses this, and with about 70 completed steel blocks in his hands, he finally begins to make the sword.
"<>"
The steel blocks seem to emit a pale light, and then they change their shape in no time at all. Then it takes the form of a sword. It takes about five seconds. Even so, Jin is holding back. If he really meant it, he could complete it in one second.
"Oh, wow! Jin-dono, may I have a look at it?
Gloria couldn't keep quiet. Jin laughed and held out the sword.
"I haven't even finished the hilt yet.
Gloria takes the sword and looks at it.
"Hmmm, nice work! I don't often use a longsword, but this one is quite easy to use."
"Is it? I used the sample sword and the sword that Heinz-san was holding earlier as reference.
Gloria was surprised when Jin answered. At the same time, the princess also raised her voice.
"What! Heinz's sword is unmarked, but it's a work of art!"
"What! How did you know the details of the sword in such a short time?
The details of the sword were different from the point of surprise.
"Well, I'm relieved to hear that it's of good quality.
Jin said and went back to his work. Elsa and Reiko had finished making 100 pieces of steel.
"<>. <>. <>"
The swords were completed one after another. 100 swords were made in about 15 minutes.
"That was fast!"
The princess and Gloria are both looking on in astonishment.
"Now all we have to do is harden them..."
Jin began to explain again to Erza.
"You explained it at Mr. Duston's place, didn't you? Keep that in mind as you watch."
Jin said, and picked up about ten swords in a single motion.
The onlookers are silent as Jin processes ten swords in a single operation. The whole process takes about 30 seconds, and in a little over five minutes, 100 swords are completed.
"Now all that's left is the sheath, the brim, and the hilt. Elsa can do this too.
"Tsubaki?"
Erza looked doubtful at the unfamiliar word.
"Oh, for swords, it's called a guard, isn't it?"
Gloria answered.
"Yes. In our country, a sword with a hilt and a tsuba is called a hilt. The sword you are having made now has the hilt and tsuba made separately, so you can call it a guard.
"Okay. Would you be okay with that, Elsa?
"Yes, that's fine."
With that, Jin prepared the leather for the scabbard, the brass for the guard, and the hardwood for the handle. He asked Erza to make a brass guard.
Jin shows her a sample of what he wants it to look like.
I'll do the fine tuning," he says.
"I'll try."
Elsa separates the amount of brass to be used as a guard from the mass of brass. Jin sees this and is impressed by how well she has done in such a short time.
Seeing him forming the guard by forming, Jin was relieved that he could leave the work to her and started to make the scabbard and handle himself.
Reiko took the materials while Jin was in charge of processing.
In no time at all, the scabbard and handle were ready.
"Wow, this is fun!
Hannah was also looking at them with delight. This too was completed in about 10 minutes. Elsa has only made 20 pieces.
"I'm sorry I'm late," she apologizes.
She apologizes, but it's just that Jin is too crazy, and Elsa is fast enough. It is a tragedy of having a family member who is too good.
Jin attaches the completed guard to the sword, adjusts the hilt, and fine-tunes the sword. Finally, he sheathes the sword and the sword is complete.
Hitoshi used to change the color of the scabbard little by little.
Every 10 strikes, the color of the scabbard is a gradation of brown, from almost white to almost black.
"Hmmm, it's quite beautiful.
Gloria, who was watching, was also impressed. Princess Rieschen is looking at it with Hannah. She is not bored.
When the guards prepared by Elsa are used up, Jin helps her to make more guards.
It was about 2:30 when the 100 longswords were completed.
"This is the end of the whole volume."
Jin stood up and stretched, uttering a somewhat dated line.
"Well, you showed me something good.
Gloria, the sword enthusiast, was pleased.
"Good, then we can hand it over to the Prime Minister. ...... you there, go get the Prime Minister. Tell him that Jin has completed what he asked for."
Princess Rieschen ordered a soldier passing by the workshop to go get the Prime Minister.
Inwardly, Jin wondered if he would be able to summon the Prime Minister so easily, but his fears were unfounded.
The prime minister literally flew in.
"Jiji-jin-dono, it's done!
Even his bodyguards could see him running down the corridor at a speed that would have stunned them.
"Oh, Powell's guy can make a face like that, too?"
Princess Rieschen's cheeks relaxed at the Prime Minister's panic, who usually has a wry expression on his face.
"Wheeze, wheeze, wheeze ............"
The Prime Minister, who seems to have run as fast as he could to the workshop, has a sweaty forehead and is breathing on his shoulders.
"There's no need to be in such a hurry."
The princess's half-amused words were also ringing in his ears,
"Hohohohoho, did you really complete 20 golems and 100 swords?
She asked him with an almost insatiable appetite.
"Yes, please take a look."
Jin pointed inside the workshop.
There stood twenty silver-gray golems with a dull sheen, each holding five swords in its arms.
"Oh, it's true, isn't it ......?"
"Yes, I saw her and Gloria from the middle. No doubt Jin made this many golems and swords.
For some reason, the princess is very proud.
Just when Jin was about to relax, she said, "This is the end of the request.
"How can a sword made by a magecraftsman be of any use in a real battle!
A voice reeking of trouble echoed through the room.
