The next day, Jin was in Horai Island.

"Well then, I will send 410 from craftsman 401.

"That's good. Gon and Gen are continuing to work on it, and as soon as the craftsman (Smith) arrives, we will return to the village of Kaina.

That's good about the pavement.

"Well, now we have to do what is most necessary."

.

"Yes. After I found out that the magic circle should be multi-layered, I've been trying to come up with some ideas.

Jin explains some of his ideas to the old man.

"First of all, this would require a large amount of free magical elements (ether), so the first one is an ether converter.

"The second layer would be a magical control flow (Magi Sequence) to set the range and intensity of the effect.

<>

"The third layer is ......."

In this way, Jin explained his plan.

"On the ninth layer, we will use the collected free magical elements (ether) to generate a transition space. This is an application of the shifting magic circle.

"The tenth layer has the effect of reversing the transition space.

"The boundary created by this should be a break in space."

In short, it would be like having <> with no enclosure, but with very small intervals between them.

Theoretically, the gates are connected by a space called subspace, in which the physical phenomena on the other side become almost meaningless.

In other words, physical phenomena on the other side are not transmitted to our side.

The only exception is the movement of matter, which is placed at very small intervals, so it should appear that nothing changes.

However, since the intrinsic velocity that the material had before it entered the room would be reduced to zero, it would appear as if it stopped instantly, Jin guessed.

"I doubt it. It might be worth a try.

Jin worked out the details of the project while exchanging such conversation.

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

The magic circle is not a mature system that can be completed by theory alone.

Experimentation and practice are essential.

"Okay, let's start the test."

"Yes, father."

Jin was now about to test the spatial barrier he had created on a trial basis.

The size of the field to be generated is a disc of one meter in diameter.

The size of the generator needed for this is about the size of a box of tissues. It could be made a little smaller, but this was done for the sake of ease of analysis, such as checking the operation.

"<>"

Reiko and Hitoshi are standing about 5 meters apart, Hitoshi is right next to the warding generator and Reiko is in front of it. Reiko is attacking the warding generator and Jin is observing.

"Yes, the warding is working fine.

The warding is black.

"The reason why it looks black is because no light is emitted. ......?

Jin imagined that the blackness is due to the fact that no light is emitted and no light is reflected back.

In a sense, it is the same as a black hole. This one does not absorb matter.

"It's a disc shape now, but I'd like to make it hemispherical or spherical eventually.

"Father, where would you like to start?"

Reiko asked Jin who was thinking about something.

"Oh, yes, first of all, try throwing a stone lightly.

"Yes.

Reiko throws a stone with one percent force. The stone hits the boundary with the speed of an adult throwing it as hard as he can. .......

"Okay, that's what I thought."

The velocity becomes zero, and the stone plops to the ground, pulled by gravity.

After that, I tried three more times with different sized stones, but all of them lost speed when they touched the boundary and fell to the ground.

"Okay, so far so good. Let's try magic next.

"Yes. ......<>"

Reiko fires a <<>.

The fireball aimed straight at the boundary, and when it touched the boundary, it dissipated.

"I see. Reiko, one more time.

"Yes."

Jin repeated the experiment five times.

"Yeah, in the case of magic, I wonder if it loses its < to maintain ......?"

However, even Jin could not understand why the magic was fading away.

Reiko, who is powered by magic, is not affected by the warp gate, nor is the blood that flows through the human body affected in the first place.

"I guess we'll just have to leave it as for the time being."

Being a practical person, Jin decided to focus on practical application for the time being, thinking that the theory would come later.

The experiments are done," he said. Now let's work on the second prototype.

"I see. I'll take care of it then."

The old man offers, and Jin gives his permission.

"Yes. We can have a craftsman (Smith) help us with that."

>.

** ** "I think we can call it a success first.

With this first success, Jin started to work on the application.

"If we make it spherical, there is a possibility that we will not be able to replenish free magic element (ether). ...... In that case, we can use ethenol or magic element storage stones (manacelles)."

<<

"Yes. But it will probably make it impossible to see anything outside."

It will be impossible to use any electromagnetic waves, including infrared rays.

"So that's why it goes dark for a moment when you use the warp gate."

Reiko said, as if impressed.

"Yeah, I guess that's what it means."

Jin also had an idea about this phenomenon.

The inside of the Warp Gate is illuminated and bright, but it was not his imagination that it seemed to get darker for a moment at the moment of the transition.

Reiko must have had a clearer perception than Jin.

"But if it could be the strongest barrier, it wouldn't be a bad idea to be able to deploy it even for a short time."

>.

Hearing these words of the old man, Jin came up with an idea.

"Is it possible to predict <>?"

If it is possible to do so, it would be possible to deploy the boundary a moment before the vibration and release it when the vibration subsides.

Then, perhaps it would be possible to cover the entire Ars.

The old man agrees with me.

The expectations on Jin's shoulders are growing.
