The Water Magician

Four days later, the group departed from the Holy Capital Marromar and headed towards Port Town Japorii.

As for the group...

From the Fundebie Kingdom, there were Pope Graham, Cardinal Stefania, fifty inquisitors, and several golems.

From the Naitorei Kingdom, there was King Abel the First, the B-class party 'Room 10', fifty members of the Royal Knight Order, and two squad captains.

From the Debuhi Empire, there was Duke Rubine Fiona, Count Oscar Lusk, several maids, and some imperial knights.

From the Handalu Federation, there was Robert Pirlo, the former king of the Kingdom of Capitone, Captain of the Guard Grown, and a few chamberlains.

"Hey, Ryo hasn't returned yet, right?"

"Yes, your majesty. However, we received a message just now that he is heading directly to the town of Japorii to meet us there."

The one who answered Abel's question was Eto.

"I see. Hmm? Ryo is in the West Dungeon, right? How did we get that message?"

"Yes, it seems he contacted us about a new alchemy tool made based on 'echo of the soul' that he's testing."

"Huh? A new alchemy tool made based on 'echo of the soul'?"

Abel tilted his head at Eto's answer.

Then he remembered.

The existence of 'echo of the soul'.

((Ryo, don’t be late.))

((Abel! You surprised me!))

((I don’t understand.))

((I was just about to contact you too. I'm going directly to the port town.))

((Ah, Eto told me. But something about a new alchemy tool?))

((Yes, yes. I was researching 'echo of the soul' and had an idea. Ms. Marlin gave me a magic stone, so I decided to give it a try. I had tinkered with 'echo of the soul' before, but I noticed something I hadn't at that time.))

((Hmm?))

((The essence of Kenneth's magic stone segmentation, I think it might be 'quantum entanglement'.))

((Hmm, I don't know that term.))

Yes, a word Abel did not know.

There is a phenomenon called 'quantum entanglement'.

It's a famous phenomenon that has even been a subject for the Nobel Prize in Physics.

A special existence that possesses both particle nature (the properties of matter) and wave nature (the properties of states).

This is called 'quantum'.

Well, for example, if you put two entangled particles, like two electrons, in a small box, no matter how far apart they are placed, they will still be related.

When the state of one is determined, the state of the other is also determined 'instantaneously'.

Across distances.

If you separate them over a great distance, it can create phenomena that exceed the speed of light, which is about three hundred thousand kilometers per second.

Between entangled quanta, distance becomes irrelevant.

Ryo thought that a phenomenon similar to this 'quantum entanglement' was occurring between the segmented magic stones...

That 'echo of the soul' might be utilizing a phenomenon similar to quantum entanglement to enable communication over thousands of kilometers.

Previously, in the City of Manyamia, he had tinkered with 'echo of the soul' so that messages could be delivered to the royal capital.

At that time, he honestly hadn't thought that far.

It seemed like he was using water vapor in the air to enable long-distance communication, so he made adjustments to the magic formula and delivered the message.

Of course, that wasn't wrong.

However, upon closer examination, he realized something odd.

Indeed, there is water vapor in the air.

Even if it were used to transmit information, if the distance became too long, that would be impossible.

Even Ryo could only use water attribute magic within a kilometer radius.

He couldn't deliver information across thousands of kilometers through water vapor.

However, 'echo of the soul' was able to do so.

In other words, it does not matter the distance.

Something that nullifies distance or reduces it to zero.

If demons were involved, Ryo would have suspected it was their 'gravity-type' magic or something like that.

But that was not the case.

The 'echo of the soul' in Ryo's ear and the paired ring on Abel's finger.

Slightly, the magic stone on the ear side was chipped, and it fit into Abel's ring.
