The last day of March, the 30th.

"Well, let's fix it.

Jin said, "Let's rebuild the giant Magi Puppet that Rubina had modified, and make it work again.

"Oh, yeah. I'm here to help, right?"

"What?"

"Rubina is the star of the show. You've done all this work, you can do it, can't you?

I'll do my best!

Rubina responded to Jin's words with clenched fists.

I'll help you today.

I'll do my best!

Neige and Rouge also offered their unconditional cooperation to Rubina.

"Yes, thank you."

Rubina's skills are well documented since she is the Queen of Magecraft.

The only thing left is experience, Jin thinks, so he puts her into practice every chance he gets.

"Roo-chan, hold it right there!　Ne-chan, hold this side!　I'll do the processing in the meantime!"

(Yes, he is growing up after all.)

Jin was satisfied to see Rubina giving instructions to Rouge and Neige.

But...

"Hey, Rubina, why don't you tell me what to do?　I'm kind of out of ideas."

"But what kind of instructions do you want me to give to ...... Jin-sama?

I can understand that feeling. Jin thinks it's strange that people don't mind giving orders to their superiors, even if it's only when they are working.

When Jin himself was working for a black company, he had a hard time giving instructions to a worker who was twice his age at a subsidiary factory to which he was sent.

I was left with an even stronger impression because the worker did not even try to hide the fact that he was also thinking, "What the hell are you doing, young man?

"But you know, this is just another experience," he said.

"uu......"

Rubina was still not ready to make up her mind,

"Rubina, it's not every day you get help from Master Jin, so take the plunge and give it a try," Marikka said.

Marikka also said to Rubina, "Rubina, it's not every day that Jin-sama helps you.

"Well, ......, I understand."

Rubina had no choice but to give it a try, especially since Jin and Marikka had told her so.

"Jin-sama, can you repair the distorted exterior?"

"Yes, I can."

One of the tricks to deal with such a situation is to "give them a large volume of work for the time being.

Of course, you will be in trouble if the person you ask does not have adequate ability.

And if they are too competent, they will say .......

"I'm done, what should I do next?"

They ask us to give them the next instruction before we are ready for it.

"It's too soon, Jin-sama!"

Rubina is impatient.

"Well, can you prepare the control board for me?"

"Yes, sir."

Jin replied shortly and prepared a standard link board.

"Yes, sir."

This was originally intended to be used for the large-sized Magi Puppet that Jin had modified.

"Uh ...... wow, so this is Jin-sama's standard ......."

Give me the next instruction.

"I know, ...... well, check the skeleton of the upper body and fix it if it is distorted."

"Yes, sir."

Rubina then gives instructions to Neige and Rouge.

Jin has learned from experience that when using multiple subordinates like this, the one who gives instructions should be a supervisor and not do the work himself.

Of course, it depends on the situation, but in most cases, if the supervisor himself is working, he cannot keep track of the progress of his subordinates' work, and as a result, he may end up with <, which is a waste of time.

Such a mistake at Jin's company would immediately bounce back to his appraisal, but not here.

It would be better if Rubina could gain experience in such an environment, Jin thought.

* * * *

"...... Jin-sama, please adjust the right leg. Ne-chan and Roo-chan, please adjust the left leg.

And as Jin hoped, Rubina's instructions became more and more appropriate as time went by.

（Yes, he is a man of his word.)

In Jin's case, when he gives instructions to his <s, he gives them 1, 2, 3......in stages.... ... and so on.

The trick is to have a rough idea of all the steps to be taken at this point.

In other words, it is the job of the person giving the instructions to grasp the flow of the work and to make sure that the flow is not interrupted.

It is also a viewpoint that looks down on the entire project from a higher level.

Rubina seemed to have begun to grasp this sensitively.

（She is only 10 years old. (She is only 10 years old. She will learn better by trying it first, rather than by teaching her theoretically.)

Jin thought so, and this was the time for this work.

* * * * * * * * * * * * * * *

"It's done!　...... but it took longer than I thought. ......"

We managed to finish the repair and modification before lunch.

However, Rubina was shocked to find out that what she had expected to take two hours took three and a half hours, almost twice as long as she had expected.

"Rubina, that's the difficulty of using people."

Jin spoke to Rubina as if admonishing her.

"If you work alone, it is easy to estimate the time required. But when you are working with many people, it is difficult.

"Yes, I understand.

"There are two ways of working together, one is to do simple tasks in parallel. This one is easier to understand.

Yes, it is.

The hard part is when several people are working on a task. If someone is dragging his feet, of course it will take longer.

"......, I know."

"So you have to assign the amount of work or the content of the work according to each person's ability."

"Ummm, that's difficult."

Rubina makes a reluctant face. Jin, however, smiles gently at her.

"I don't expect you to be good at everything at once. I'm not asking you to get good at everything at once, but this just happened to be a good opportunity and I wanted you to experience it.

Jin patted Rubina on the head.

"You did a good job for the first time you gave her instructions.

"Really?"

"Yes, I'm sure."

When Jin assured her, Rubina, who had been looking at him with a difficult expression for a long time, finally smiled.

"I feel a little better now. Then let's move on to the next job.

"What?　What?

"Yes. < family.

Jin told Rubina that he would work with her.

But first, let's eat.

Lunch was just about ready.
