The ground-breaking technology brought by Gran gave us the prospect of creating an accurate watch.

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

The city of Fontana is now surrounded by walls.

And in the middle of the land inside the wall is a slightly raised little hill-like terrain, where the castle of the Fontana family is built.

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

Place a clock tower high on the hill to make it visible from all over the city.

That way, you'll know that the most important thing in Fontana is not the cathedral, but the person in the Fontana family castle.

But we can't just suddenly crush the current castle and build a new one.

It is still being used as a place to carry out government affairs, and it is troubled when it is gone.

Therefore, we will first install a clock tower and then build a castle to connect with that clock tower.

As a result of various discussions, the clock tower was built at the initiative of me and Grant, and the rest of the castle was hired by the original Fontana family minister to build it.

When I asked Grant what he thought, he said it was fine.

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

"Well then, let's just make a clock tower. I was hoping to build a tower of this shape and put a clock board on the top of the tower that I could see from all directions."

"Why don't we just put four clock dials on the wall of the tower? If you just make multiple clocks of the same kind, it's not that difficult, Ars."

"Really? Do we have to adjust the gear combination to move the four clocks simultaneously?

"You don't have to do that. If we use the Valkyrie angle co-vibration phenomenon, there is no problem even if it is separated. Instead, it is easier to repair the interior when it fails without complicating the mechanism."

"Oh, I see. Should I make it less complicated? The clock tower won't need a second hand, so it can be built with minimal mechanism."

"That's not true. If only a power source using magic steel, crystal, and processed Valkyrie angles were installed inside the clock tower, we could build as many clock towers as possible thanks to the synergistic vibration phenomenon. It's possible to build the same clock tower from a distance."

"How much distance does it take to build a clock tower, for example, in Vulcania or Baltonia in the Urk District? Does that mean there's no magic steel on the spot?

"Of course it is. As long as the clock tower that should be able to be built here in Fontana is in motion, what was built elsewhere would not require magic steel. If only there were Valkyrie horns processed in the same way, it would be."

"... wait a minute. Well, suppose I made the clock tower a regular bell. If you were wearing a processed Valkyrie corner on that bell, would it vibrate the same shape of the corner? You don't need magic?

"That's right. Covibration is only a characteristic of Valkyrie's angle. Unlike magic swords and other things that don't work if you don't apply magic, magic is a phenomenon that is caused regardless of whether you have magic or not."

Oh, really?

Unlike things where vibrations resonate in close proximity like a tuning fork, you don't have to wonder where you get the energy to make that movement possible.

What kind of principle does such a thing happen? I don't know, but I think I can do it even if I say I can do the grand.

That means it's possible to ring the clock bell all over the place at exactly the same time.

When a clock stand in the city of Fontana rings a bell, keep the corner of Valkyrie on the inside of the bell so it can vibrate and sound like a bell in another place.

Worst of all, even without a clock tower, if you hang the bell, you can make a sound at the same time.

... or maybe there are more ways to make use of it.

I can't think of Pa, but I remembered Yarn Phone when I heard Gran's story.

Connect the thread to the bottom of the two paper cups, one talking to the paper cup and the other to the ear.

The vibration conveyed by the yarn causes the other person's voice to be heard even if it is far away.

I thought this would lead to telephone technology, but at present, I don't think we need it right away, as long as we have the [prelude] of the Reed family.

But I also feel that it can be used in addition to the telephone.

Shit.

Even though the performance of Valkyrie is amazing, it is surprising that there are various ways to utilize it.

It will become more and more important.

Once again I realized Valkyrie's greatness in my conversation with Gran, I politely brushed every Valkyrie in the city of Fontana that day to show my gratitude.
