Reiko was consulting with the old man using the built-in manacam (magic element communication device).

"Your father looks very happy. I have not seen him so happy for some time now.

"Yes. I don't think it's a change of scenery, but rather that your father is essentially suited to this kind of life."

"Therefore, I think it is necessary to create a system that can deal with the Unification Party (Unifiler) without your father.

"Please, sir. I have to protect my father here.

I have to stay here and protect my father.

Thus, we decided to enhance the system of Horai Island without Jin to reduce his burden, and also to establish a system to realize his ideas as quickly as possible.

The old man decided to prepare another 500 Smith Golems.

The work is easy or rather a process of flow work, since there is a template.

By fully utilizing the existing Smith Golems, a total of 1,000 Smith Golems were assembled in such a short period of time that it could be said that the process was quick.

The control core (control core) is a copy, so it was possible even without Jin.

>.

The old man has taken full advantage of his authority to reorganize the craftsmen (smiths) golem, and has set in motion the quickest way possible to realize Jin's idea.

"Wow, Gon and Gen, long time no see!

It's the afternoon after returning from a picnic of medicinal herbs.

Hannah was so happy to see Gon and Gen, who had come to show themselves in a dignified manner.

She is hanging on Gon's arm or being carried on Gen's shoulders.

Jin was still keeping quiet about Hanna's special covert task force (SP).

What he is doing is building a washing machine with Erza as his assistant.

Last year, we did not notice it, but Martha and the other women in Kaina village had rough hands after the winter.

One of the reasons for this is washing clothes.

In Kayna village, there was not even a washboard, and most of the washing was done by hand in a large washtub. Large items such as bed sheets were washed by stepping on them with one's feet.

Although hot spring water is available, it is still a difficult task.

It happens every year," he said. It will get better when it gets warmer.

Martha laughed, but Jin was not convinced.

That's where the washing machine comes in.

He envisioned a hand-cranked washing machine. The laundry, detergent, and water are placed in an egg-shaped container, and when the handle is turned, the container spins and the laundry is agitated inside.

Jin thought that an ordinary automatic washing machine would be difficult to operate and, although it may be selfish of him, it would not be suitable for the village of Kaina.

The missing materials were brought from Hourai Island. Well, most of them were made from bronze, copper, and iron left in Martha's house.

Erza is still an apprentice, so she is still observing.

Her eyes were serious as she stared at Jin working the metal by forming.

"The most important thing in forming is to have an image. Imagine from beginning to end what kind of shape you want to make. That's the best trick.

Jin slowly builds up the washing machine, using forming to show us how he does it.

"The image ...... is difficult. Do you mean that I have to have a clear picture in my mind of what I want to make?

"Yes, that's right. Yes. You have to start with a simple shape at first.

While talking like this, Erza does not know that Jin is out of his league when it comes to forming without chanting. She is striving to be able to do the same.

It is too high a goal to strive for, but it will not be in vain.

In the meantime, the hand-cranked washing machine is completed. Reiko asked me to get the leather of the hexenbiest to use as packing material. Without it, water would leak out and splash all over the place when the machine is turned.

Natural rubber would have been fine, but it would not be as durable.

"Interesting shape"

Erza expressed her honest opinion when she saw the completed washing machine. Hannah came over and looked at it with interest.

"What's this?

"This is a washing machine. Is there anything you want to wash?

Jin asked Hannah if there was anything she wanted to try. Then Hannah said,

"Yes, I do!　I changed my pants yesterday.

and went to the laundry room to get them. Jin and Elsa look at her with a wry smile.

Reiko takes the prototype hand-cranked washing machine and we go to the well. The sun was shining and a few women were chatting with each other.

"Oh, Jin, isn't it? Did you cook something again?

"You're Jin's sister, aren't you?　You don't look much like her. But she is beautiful.

She was approached by someone who said something like "You're a beautiful woman. When she was told to her face that she was a beautiful woman, Elsa's cheeks turned red with surprise.

"This is called a washing machine," she said.

Jin opened the lid of the washing machine, put in Hanna's pants, and poured in water from the well. Finally, he poured a small amount of Rita's seed powder as detergent. Then he closes the lid.

The ladies at the well are watching with great interest.

"And then I turn this handle."

The size of the washing machine is for one person, as it is a prototype. The size of the washing machine is for one person, as it is a prototype, and the amount of laundry in the village is not so large that this size is sufficient.

The larger the machine, the more power it would require to spin the clothes, and that would make it more difficult to spin the clothes. There is an option to have Gon or Gen do it.

After spinning the wheel around and around for about three minutes, Jin stopped. The washing tank slowly slowed down and stopped with the lid up to balance the weight of the tank.

"Open the bottom stopper and let the water out.

Dirty water comes out. (To Hannah's credit, it is not really "dirty". It means water after washing.)

Fill the rinse water.

Close the stopper at the bottom and now pour the water through the lid.

"Turn it again."

While turning it, Jin said,

"Oh, that's right. If it's not too dirty, you can clean it with just water.

With this remark, he kept turning the water for about one minute this time.

After changing the water again, Jin said that he would finish next time, and then turned the water with the bottom stopper open. The water splashed a little.

You can squeeze it like this. Of course, you can squeeze it by hand.

After explaining the process, he stops the washing machine, opens the lid, and takes out Hanna's pants.

"Now, open the lid and take out the laundry.

She then pats the clothes dry and stretches out the wrinkles.

"All that's left is to hang them out to dry."

How do you like it?　Jin looks around at the ladies' faces.

"......"

"............"

Just when Jin thought they were not responding well.

"Jin!　You can wash more things with this, right?"

"Make one for me!"

"Sounds fun!"

The hand-cranked washing machine seems to have been accepted in the village of Kaina, though more for fun than convenience.

"Thank you for washing my clothes, Onii-chan!

Hannah's smile made Jin the happiest.

He arranged through Reiko to have the washing machine mass-produced and brought to Horai Island.

Jin, of course, and Erza were to stay one more night.

Meane, who talked to Erza through the manacam, said <>.

"Brother Jin, you looked so good today."

Erza said suddenly after dinner.

"What?"

Jin was not sure what she meant.

"The past few days, Jin, you sometimes looked so sad. But today you seemed to be having a great time all day.

"I see. ......"

Jin thinks about what Erza said to him. Inwardly, he had an idea.

(I guess I was tired from the Unification Party (Unifiler) and so on.)

Jin smiles bitterly and wonders if he is not suited for rough work after all.

"Hey, Erza, can you use magic too?

Hannah, who was helping to wash dishes, asked Erza as soon as she came back.

"No, but I'm not as good as my brother Jin. But I'm not as good as my brother Jin."

But Hannah looked at Erza expectantly with sparkling eyes,

"Show me something you can do!

She said, "Show me something. Elsa thought for a moment and then noticed that the kitchen where Martha was sitting was dimly lit,

She chanted "<>" and turned on the light.

and turned on the light. The kitchen becomes bright at once. Martha is surprised.

"Wow!　I was surprised. ...... Oh, it's you, Elsa. Is this magic too?　How convenient!

Erza saw the scene and said

"Enriching people's lives with magic is very rewarding, isn't it?"

Hearing these words, Jin smiled and turned to Erza,

"You've found a good point. I'm sure Erza will make a good magecraftsman.

He said.

Really?　Thank you, Brother Jin.

Erza smiled with happiness when she was told this. This smile was something Jin had never seen before.
