After reviewing the flow of magical control (magi sequence), Jin thought of the method he used for the old man.

"Yes, if we increase the number of control cores in Reiko, we can expect an improvement in processing speed.

So Jin decides to increase the number of control cores in Reiko by one.

This is not a fully parallel processing, but a co-processor like in a PC.

By using this coprocessor to process sensory data such as <>, the main control nucleus (control core) will be relieved from heavy load.

As a safety measure, the control core is set to shut out tactile information when necessary.

"All right Reiko, wake up!"

Finally, the new Reiko is on the move. Jin takes Reiko outside with him. Jin is relieved to see that there is no awkwardness in her movements.

"How are you feeling?"

Jin asked Reiko at the central square in front of the institute.

"Yes, Father. "Yes, Father. I can see what's going on around me more than ever. I can even feel the wind on my cheeks."

"Well, that's a success. Well then, let's increase the speed and see if there are any glitches. First, do a vertical jump. ...... Don't do it all at once, okay?"

"Okay."

Reiko moved a little away from Jin and jumped on the spot first.

Fifty centimeters, sixty centimeters, one meter. Then 2 meters, 3 meters. Finally, she jumped up about 10 meters.

There was hardly a sound or a cloud of dust when I landed, indicating that Reiko was in perfect control of her body.

"Good, Reiko. Next!"

This time she starts to run. And when she reaches the edge of the central square, she changes direction at once and comes running back. At a speed of about 100 kilometers per hour. And he barely makes a footstep.

"Father, it's wonderful."

Reiko, too, is able to appropriately process tactile information and reflect it in her actions.

"I used to be very careful to control the force, but not anymore. I can increase or decrease the power output as I wish.

Saying this, Reiko picked up a dead branch that had fallen near her.

"Let me bend it just enough so that it doesn't break."

Reiko picked up the dead branch with the index fingers and thumbs of both hands and bent it slowly.

"Now, I'm doing it at 100 percent output.

Reiko's 100 percent was enough to move several tons. Despite this, the dead branch did not break. She is able to control the force to a few hundred thousandths of a percent.

"Okay, that's enough."

Jin finished the test.

"It was a great success. But if there are any problems in the future, you must tell me.

"Yes, father."

Now Reiko should be able to use all the swordplay and fighting techniques she's learned.

"Well, I hope I never have to use it. ......

* * * *

Jin wondered how Elsa was doing and peeked into the workshop on the first floor.

"Elsa, how are you ...... doing?

"Oh, Brother Jin."

Elsa had just finished the mascot itself.

"Oh, a doll with black hair."

Jin had prepared various colors of thread for the hair, including black, brown, red, yellow, blue, gold, and silver, but Erza chose black.

She had not dressed her yet. Her black hair, cut at her shoulders, looks somewhat like Reiko's. "I just wanted to ask you a question," she says.

"I just had a question I wanted to ask you. How can I add color to the ...... fabric?"

"Oh, right."

The knowledge did not seem to have been transferred. Jin asked Reiko to fetch some dyes.

"Father, is this what you want?"

Reiko brought a magic dye.

On the modern earth, there is a solution used to measure pH, which changes color from red to yellow, green, blue, and purple, but magic dyes change color depending on the amount of magic power applied.

The cloth dyes are slightly different from the ones used for dyeing hair before, and once dyed, they are difficult to remove.

"Yes, that's fine. Thank you very much.

Jin took the magic dye and began to explain it to Erza.

"Dissolve this in water and soak the cloth. While it is still wet, if you give it magic power, the color will turn red, and if you add more, it will turn orange, yellow, yellowish green, green, blue ......, blue purple, purple, and finally reddish purple. When the color you want is reached, stop the magic and let it dry. Once it dries, the color will never change again. The intensity of the color can be adjusted by the amount of water used to mix it.

"Yes, okay."

Erza took it and went to use it immediately.

"Oh, wait a minute."

"?"

Jin stopped her and asked Reiko to bring the raw rubber solution and sulfur.

"If you use them as they are, it will be hard to remove the color from your hands. Besides, the girl mustn't get her hands dirty.

"...... yeah."

I understand what she means, but I can't connect that with the raw rubber, so I can't help but make a dubious face at Elsa.

"So, we put sulfur in the raw rubber and <> it. Then, I put my hand in this."

"Huh?"

Jin took the initiative in sticking his hand into the rubber solution, and Elsa did the same.

Since she was wearing short sleeves, she covered about 10 cm from her wrists with the rubber and performed <>. Elsa imitated him.

"Okay, okay, and finally, <>. You have to peel it off from your hand."

Elsa did the same and peeled the thin rubber membrane from her hand, finally realizing what Jin had made.

"...... rubber gloves?"

"Yes. You can use them when you handle dirty things or when you don't want to get your hands dirty."

"Okay. Thank you, brother Jin.

"There's plenty of rubber left, and you should make extra in case they tear. ...... and make some more for Meane, Martha, and Hannah and the others later, okay?"

"Yeah, okay. I'll leave it to you."

Erza nodded and started to work on the task at hand, dyeing the cloth. Jin watches her and, seeing no problems, turns to Reiko.

"Reiko, let's take a look around, shall we?

"Yes, father."

Elsa instructs the old man to send a craftsman golem to support her.

"Ah, you've done a good job."

Jin had come with Reiko to see the fields of Horai Island.

The fruit trees that were originally on the island, Persica (peach), Citran (orange), Apulle (apple), Ramon (lemon), Maruon (chestnut), and Ornut (walnut).

In the field, wheat, barley, black-eyed peas, akame (azuki beans), round peas (soybeans), and so on.

Before long, the variety of legumes has increased.

Vegetables, too, were planted in a variety that Jin had never seen before.

And then there was cane.

"Is this what you found in the southern part of the Kingdom of Celuloa?

The fifth column (quinta) dispatched to the Kingdom of Celuloa had found it and brought it here. Jin only found out about it recently.

This is because the report was made to Jin after verifying whether or not sugar could really be extracted. In addition, Jin was busy with many other things, and the old man could not find the right time to report it.

Sugar was expensive, but he had purchased and stockpiled a good amount of it, so it was less urgent.

"Now we can be quite self-sufficient.

Jin is quite satisfied. All that remained was for the fifth column (quinta) that had been dispatched to the Shoro Empire to bring back rice.

"Well, let's not inspect the fields. Well then, Reiko, let's go back to the laboratory.

After a change of pace from looking at the green fields, Jin started to make something he had been thinking about for a long time.

All he needed was azuki beans, white sugar, and a pinch of salt.

Yes, Jin is going to make red bean paste.

Let's see, 2 kilograms of azuki beans, 2.5 kilograms of sugar, and salt, I think it was 1/120th of the sugar. Salt is 1/120th of sugar, so 20.8 grams.

The red-eyed peas are cooked over high heat, and when they come to a boil, water is added, the water is brought to a boil again, the heat is turned off, and the cooking water is discarded.

Add water and simmer again. Remove any scum that comes to the surface. Keep the heat low.

When the water becomes soft, turn off the heat and add water little by little to the pot, stopping when the pot overflows with water, and drain in a colander.

Add sugar and salt, mix well and cook over medium heat.

Stir to prevent burning, and when the water is gone, turn off the heat and mash the red beans.

When it cools down, the red bean paste is ready.

The time required is 2 hours. This is how to make red bean paste that I learned at the orphanage.

When it was just about lunch time in Kaina village time, Jin asked Reiko to take a pot of freshly made sweet bean paste and went to call Erza.

"Hey, Erza, it's lunchtime, let's go back to the village.

"Oh, brother Jin, I just finished it."

Erza also said that she had finished the mascot doll and showed it to Jin.

"Well, that's nice," she said.

She wears her black hair cut at her shoulders and has strikingly rounded black eyes. She is wearing a deep blue dress with a white collar and long sleeves. The collar is white and the hem of the long skirt is decorated with lace.

Jin was impressed by the girlish workmanship of the dress. Jin could not have designed the dress to this extent, notwithstanding his production skills.

"Lace, Smith 1 brought it out and I used it.

"Yeah, I think it's a good accent. You have improved, Elsa.

Jin was happy to see Erza's growth in a short period of time, even though she had transferred her knowledge.

Then Erza's nose twitched.

"?　...... smells sweet."

Jin replies with a smile.

"Oh, I made some sweet bean paste. Let's go back to the village for lunch.
