The groundbreaking technology brought by Gran gave us the prospect of making an accurate watch.

So I'm going to build a clock tower quickly.

Currently, the city of Fontana is surrounded by walls.

And the center of the land in its walls has a slightly uplifting little hilly terrain, where the castle of the Fontana family is built.

The Archdiocese for Archbishop Paul will be built on newly planned land, but the castle will be built on this hill.

Set up a clock tower in a high position called the hill so that it can be seen from all over the city.

That should help you understand that the most important thing in this Fontana is not the cathedral, but the person in the castle of the Fontana family.

but you can't just suddenly crush the current castle and build a new one.

It is still being used as a place to conduct business, and when it is gone, it is difficult.

Therefore, a clock tower is to be set up first, after which a castle is to be built to connect with that clock tower.

After much discussion, the clock tower was built so that me and Gran would take the lead, and the other castle parts were to be built by the original minister of the Fontana family hired by the architects.

I asked him what he thought of Gran, and he said it was okay.

Instead, he was pleased that it would be a good stimulus because he would be building a castle in collaboration with a prominent architect.

"Shall we just make a clock tower, then? For once, I'm going to build a tower like this, and I'm going to put on a clockboard at the top of the tower that I can see from four directions."

"Would you just put four clockboards on the wall of the tower? It's not that difficult to make more than one clock, Lord Ars."

"Really? Do we have to adjust the gear combination so that we move the four watchboards at the same time?

"You don't have to do that. Using the co-oscillating phenomenon of the corners of the Valkyrie, it is not a problem to separate it. It's easier to repair the interior when it fails than it is to use a complicated mechanism."

"Oh, I see. Should I not complicate the making? The clock tower won't even need a second hand, which means you can make it with minimal mechanism."

"It is. If only a power source was installed inside the clock tower using electromagnetic steel, crystals and machined Valkyrie horns, we could create as many clock towers as possible thanks to the co-oscillation phenomenon. It's also possible to build the same clock tower over a long distance."

"How much at a distance, for example, does it matter if you build a clock tower in Balkania or Baltonia in the Urk District? So you're saying there doesn't have to be any magic and electric steel on the spot?

"Of course I am. As long as the clock tower that should be able to be found here in the city of Fontana is in motion, what has been made elsewhere does not require an electromagnetic steel. As long as the horns of the Valkyrie are machined into the same shape,"

"... wait a minute. Let's say you made a clock tower bell that rings at regular intervals. If you had a processed Valkyrie horn on that bell, would that vibrate the same shape of horn? You don't need magic or anything?

"Exactly. Co-vibratory phenomena are only attributes of Valkyrie's horns. Unlike magic swords and other things that don't work unless you pour magic into them, whether or not you have magic is a phenomenon that can be triggered."

Seriously.

I don't have to wonder where you're getting the energy to allow that movement when it's different from something that vibrations resonate in close proximity like a fork.

I guess I can do that more than just say I can pin but gran what principles would make that happen.

That would mean that it would also be possible to ring the clockbench bells at exactly the same time everywhere.

When a clock stand in the city of Fontana rings a bell, even inside that bell, if you put a Valkyrie horn on it, it is also possible to vibrate and sound to reproduce the movement of the bell in another land.

Worst of all, you mean you can even hang a bell without a clock tower and make a noise at the same time?

... or would there be a better way to make use of it?

I can't think of a puff, but when I heard about Gran, I remembered the thread phone.

Connect the thread to the bottom part of the two paper cups and one speaks toward the paper cup and the other hits the ear.

Then the vibration that transmitted the thread means that you can hear the other person even if they are far away.

I thought this would lead to telephone technology, but as things stand, it won't be what I need any sooner than I have the [mindset] of the Reed family.

but I also feel I can make use of it besides the phone.

Shit.

Even though Valkyrie's performance is amazing, I'm surprised there are even various ways to make use of it.

Wouldn't it get more and more important?

Once again in conversation with Gran, I realized how great Valkyrie was, and that day I showed my gratitude by carefully brushing every head of Valkyrie in the city of Fontana.
