Because of its affinity with magic and magic power, and because of its too large capacity, there was no detectable magic power leaking from inside Reiko's body.
"Hmmm, normally there should be about 100 times this much leaking out."
That's how efficient the use of magic power is.
"Wait a minute. Could it be ......?"
Jin went to the window with Reiko to confirm what had just occurred to him.
"Reiko, I think I can do some magic ...... with a <>. Just shoot a ball of light outward.
"Yes, I understand."
Nodding to Jin's instruction, Reiko extends her right arm and starts chanting.
"<>......!
"Uh-oh!"
Another ball of light, a little exaggerated to say that the sun was shining, was released.
"Oh, Father, I'm so sorry ......!
Reiko is afraid that she has startled Jin. But Jin was not angry. He was holding his eyes and thinking.
"Well,...... the mental wave is the same as the magic wave,...... so the ancient dragon's leather should not leak the mental wave,...... but,...... it's not a good idea to use the dragon's leather. ......"
Jin asked another question that came to mind.
"Reiko, do you have a supply of free magical element (ether)?"
I thought that if the mental waves could not penetrate the ancient dragon's leather, the free magical element (ether) in the space could not be gathered either.
"Yes, that's not a problem at all, is it?"
"I see. ...... hmmm..."
Again Jin pondered.
"...... sure, if leather is impervious to free magic element (ether), then ancient dragons may also be lacking in free magic element (ether). ......"
It is hard to think that the free magic element (ether) contained in the air taken in by breathing is enough to support such a huge body. It is thought that the magic core in the skin and inside the body is also converted into energy.
It is also assumed that the free magical element (ether) is originally a much smaller particle than protons and neutrons. In other words, it can penetrate even reinforced leather.
So there is no problem to take in <>."
Since this is a fact, Jin decides to assume it for the time being.
"The characteristic of dragon leather is that it can be controlled by one's own magic wave,...... so maybe it can be adjusted by one's own will?"
Jin guessed that much and decided to verify it for the time being.
"Reiko, please release the light ball again.
"Okay. ......<"
"<>"
Jin does not look at the light itself this time, but follows the flow of magic power. And then he found out...
"Haaaa....... The free magic element (ether) that the skin took in was working?"
In other words, the ancient dragon leather, which is the skin, was taking in free magical element (ether), converting it into magical element (mana), and boosting the magic in sync with Reiko's mental waves.
"This is going to be difficult to adjust ......"
It is a problem that the least powerful magic becomes the largest.
It is like a flamethrower when you want to light a match, or perhaps even worse.
Even though Reiko is a physical attacker, this was a big deal.
If she could not use engineering magic properly, she would not be able to help Jin as his assistant. Reiko herself knows this, and she looks worried.
The old man offered his advice to Jin, who was troubled.
"Ah, yes, you're right. First of all, ......"
The first one is the individual recognition represented by the warp gate.
"How could she use the warp gate?"
Reiko's body did not emit enough magic power to identify individuals.
"...... Oh, the pendant."
The pendant that hangs from Reiko's neck. When Jin made the guard ring and other magic tools, he also made this pendant and gave it to Reiko.
Since it has Jin's magic pattern, it worked as a recognition vote for Reiko.
Now, the only parts of Reiko's body that are not covered by the ancient dragon's leather are her eyes, mouth, nose, and earholes.
The leaks from these holes are not enough to react to the individual recognition magic tool.
"Well, I guess we can handle that one. ......"
Worst case scenario, you could have a pendant-like magical tool.
The problem is controlling the power of magic.
"Can you consciously suppress the boost from the skin?"
"Father, the control is very delicate. It seems unlikely that it can be adjusted on the spur of the moment."
"Hmm, I see. ......"
Sometimes it can be too strong.
"Speaking of control, I'm a wand ......"
Mages use wands to increase directionality, convergence, and control.
Emitting magic directly from the palm or other parts of the body is not very good in terms of convergence and directionality.
"So, is there something like a pole?
Jin straightened his arms.
Jin straightens his arm. His index finger pointed at the target. Jin looked at the tip of the finger, and a thought came to him.
A nail!
"Father?"
Jin, who had been thinking about it, suddenly shouted out loud, and Reiko looked doubtful.
"Nails, Reiko. If we make your claws the poles of magic, you should be able to release magic from them.
Saying this, Jin began to rummage through the ancient dragon's leather.
"Here it is. We can use this."
Jin found what he thought was the leg of an ancient dragon among the scraps.
"Look, this part is thick and hard. Let's use it as a claw.
The claw is connected to the bone of the fingertip on the inside and becomes a pole to release magic.
For good measure, the toenails were modified in the same way.
What do you think, Reiko?
"Yes, I'll give it a try."
With that, Reiko reached out her hand through the window and released a spell.
"<>"
A normal ball of light is released.
"Father, it's rather easier than before!
"Then we have succeeded, haven't we?"
"Yes, this is great!"
After that, after trying various methods, I found that if there is even one , it is easy to control the power of the magic.
"In other words, until now, it was difficult to control magic because the mental wave to control it would spread over the entire skin. But if there is a pole of activation, it is easy to control because you only need to concentrate on that pole.
Jin was relieved.
"Now I just need to practice a little to get used to the control.
After thinking about it, Jin said to Reiko.
"Practice, father?"
"Yes. The point is to store the control data.
>
The old man seemed to be unsure of Jin's true intentions.
"Ah, didn't the road connecting Klein Kingdom and Egelea Kingdom pass through the old Leonard Kingdom? I thought it would be a good idea to secretly maintain that road.
This would be beneficial to the kingdoms of Klein and Egelea, with whom Jin has a close relationship, and it would also keep the Kingdom of Selroa, which is not exactly hostile to Jin, in check.
"Besides, we would like to be able to go there from the village of Kaina in the future."

"Okay, I'll go there tomorrow morning.
The sun was about to set.
Then Saki and Erza arrived. They were making something together, judging from what they were holding in their hands.
"Hey Jin, there you are. Were you working on something?
"Yeah, actually. ......"
Jin gave them a brief explanation.
"......You're right, I can understand that theory."
"Hmm, such a harm,......."
"......That's why I said you should talk to Saki and Jin."
"That's fine. It's worth thinking for yourself!"
Jin asks them a question.
"Speaking of which, what were you two doing?
Saki does not answer the question directly, but unfolds something in her hand and shows it to them.
"Take a look at this."
It was a leather vest. And what was it made of?
"Ancient dragon leather ......?"
"Yes, that's right! I came up with the idea and Erza made it. It's a present for Jin."
