In Horai Island in the year 3900 of the continental calendar, Jin was unusually busy.
Whenever he has free time, he is either making something or getting into trouble ......, so it is rare that he has free time.

Jin thought of doing something that had been on his mind but had been left unattended because of its rather low priority, now that he has more time to spare.
It is a counterpart to a

Thinly molded magic crystals are used for the diaphragm, and the sound is converted into magic power like a dynamic microphone.

This was Jin's conclusion.

Incidentally, there is a
This device shines a laser beam on the glass in the room to be eavesdropped and measures the reflected wave.
Since the glass is vibrating with sound waves at this time, the returning laser beam will have sound waves on it.

...... is a rough explanation.
Of course, Jin had heard of the principle and had thought about using it, but he had given up the development because of its disadvantages, such as the fact that it was effective only in a room and that it could not be used with materials that absorb sound waves, such as clay walls.

Jin spent two days to develop this method.
The diaphragm could be replaced by the application of a solid physical barrier.
Invisible boundaries are maintained by invisible magic, and the vibrations are used as a carrier wave for free magic element (ether) ...... waves.

"Yes, I think I can manage that."
The problem was the strength of the solid barrier, which is equivalent to a vibrating plate.
If it was too strong, the sound would not be audible because it would not vibrate. If it is too weak, it will be too noisy to pick up the important sounds.

In the case of vision, the image is blurred if it is not firmly fixed, but in the case of audio, the noise only increases, but it can be heard well enough depending on the adjustment.
Since visual information is not so necessary for eavesdropping on the contents of meetings, this technology is expected to be very useful in the future.

Jin laughed inwardly, thinking that what the old man meant by "in the near future" must be in the order of 100 years.

(Come to think of it, he also said that the Sea of Trees at Fuji was a forest formed after the eruption that took place a little over 1000 years ago.)
(By the way, did I mention that the Sea of Trees in Fuji was formed after the eruption that occurred a little more than 1,000 years ago?
Thus, there are other examples where the landscapes we can see in modern Japan have a surprisingly short history.

Oni Oshidashi, a sightseeing area at the foot of Mt. Asama, which rises on the border between Nagano and Gunma prefectures, dates back to 1783, while Mt. Bandai and a group of lakes and marshes including Lake Hibarako, which are scattered at its foot, were created by an eruption and explosion in the middle of Meiji Era (1888).
(I remember the director of the facility where Jin grew up said that the scenery was not like this back then whenever he saw Mt.)
The director of the facility where Jin grew up was a fan of historical dramas, but he was also a maniac in terms of historical research.

For example, he said that Zenkoji Temple in Shinano had burned down and had only a temporary main building during the time of Mito Komon, and that inns were not so well maintained in that era.
But at the same time, it is a fact that they enjoyed any period drama in their own way.
