After accepting Dikao's order, Josh ran all the way and finally returned to Hesler six days later.

After I came back, I felt my butt start to hurt slightly.

At Nitia's house, she took out the things from the space ring with Selena, and dozens of parts almost filled the living room.

The house is not big, it's just that Nitia bought her own living, and she hasn't bought a servant or something, so the house that wasn't originally small suddenly became a little cramped.

Selena didn't know anything about these parts, but just helped her place the position and started to daze.

"Stop being idle, look at this!"

Nitea took out Dikao's password book, flipped through a few pages and threw it to Selena.

Selena took it and nodded, then sat on the chair and looked over.

After Niteya began to look at the parts, she began to assemble them on her own.

As a result, Selena came over just as soon as she assembled without two parts.

“Is there anything you need help with?”

"You finished reading?"

"Well, that one is only eighty-two pages." Selena nodded.

"Sometimes I really envy you for your memory..." Nitia shook her head and pointed to a large part next to her, "Just bring that one."

Selena walked over and helped move over.

This password book by Dikao has written a password of fifty words on each page.

The horror of Selena's memory is that she doesn't need to look carefully, and she will never forget it as long as she looks at it like a scan.

She could even accurately draw a leaf she saw accidentally when she was four years old!

Even though I didn’t look at anything carefully at that time, when I recalled it, as long as this thing appeared in her field of vision, I could remember all the details!

When I was a child, Selena didn’t know that she was different from others, so when others said they had forgotten something, they always felt confused.

What does it mean to forget? Do you remember what you have seen before?

Until now, Selena couldn't understand what the so-called "forgottenness" really feels like.

Niteya once did many experiments for her and wanted to analyze her ability through alchemy, but unfortunately she failed.

...

"Is this installed here?" Selena asked with a part.

"Don't be sure, you must first carve the magic array."

"Magic Formation?" Selena didn't understand a little.

"Nonsense, how can I drive it without a magic circle?" Netiya was too lazy to explain, so she just shut up and obeyed the command.

Selena helped assemble parts under the command of Nitia, and after an hour, she finally got two metal products that looked like spire-shaped.

It is about 1.5 meters tall, and the bottom looks as big as a four-person coffee table.

"Is this the telegraph machine that Dikao mentioned?" Selena looked curious, "How to use it?"

"According to his words, just take a picture of this place according to different lengths." Niteya pointed to a place below that was obviously different from the surroundings.

"How to supply energy?" Selena asked.

"this!"

Nitia took out two soccer-sized crystal balls from her space ring.

"Demon-gathering ball?"

Selena knew that this thing was a must-have item for alchemists, and sometimes it was used as a substitute for insufficient magic.

"Anyway, try it, you can move that one to the other." Niteya pointed to the corner of the living room.

"oh."

Selena carried the charter flight weighing more than 300 kilograms to the other side of the living room and gently put it down.

"There is a lid behind it. After opening it, put the magic storage ball into the slot."

Selena obediently and did what she said.

"Pull down the wrench next to it!"

"Click!"

As Selena pulled down the wrench, a light began to shine between the two metal rods on the top of the telegraph.

"Si~~"

A blue current lights up, twisting between the two metal rods, and even tends to extend into the surrounding air.

However, the electric current visible to the naked eye only extends to the air at a length of less than five centimeters.

However, Selena has the magic of thunder attributes and can feel that the current between the two telegraph machines can actually be connected together.

It's just that it can't be seen with the naked eye, but she can feel it with the thunder attribute.

"It should be no problem." Selena nodded.

"Try it first."

As he said that, Nydia put her hand on the huge button in front and began to press it.

A blue light began to flash in front of Selena's button.

It flashed one after another, and then the frequency of the flashed slowed down a little.

"Can you see!" Selena nodded excitedly.

"Okay, then try a little further away." Niteya said, "You take that one to the street opposite."

Selena agreed and went downstairs with her equipment.

Nitia estimated the time and began to look through the password book.

After estimating that the time was about the same, I came to the device again and pressed the button.

After a while, Selena rushed up from downstairs and said angrily: "You are the fool!"

"Well, it seems that the accuracy of the signal is OK," Niteya nodded, "Next, move to your house a little further."

Selena turned and went downstairs again, and Nitia looked through the password book again.

Selena's house is still a bit far from Nydia, and this experiment took an hour.

More than an hour later, Selena jumped in from the second floor window, "I'm going to beat you up if I scold me again!"

"Don't be so emotional, this is to confirm the accuracy of the experiment." Niteya said calmly with the codebook, "You can try it outside the city before dawn."

…………

In the next three days, the two of them were doing various experiments every night, and the distance increased little by little.

And Nitia also tested the energy supply limit of a magic storage ball, which was about three hours.

The key is that this magic-accumulating ball has a large capacity, and it takes half of Selena's magic to fill one.

It will take at least half of the magic power to be replenished.

Selena was helpless. It seemed that the idea of ​​chatting with Dikao at any time was impossible. After all, the magic supply could not keep up.

But the limit distance has been tested and it can actually go from Hesler to the center of Silver Light City!

This distance can be said to be quite terrifying. You should know that the two places are nearly 800 kilometers apart.

However, this target distance is obviously not enough to talk to Dikao at any time, so Nitia asked Josh to send him a letter and call Dikao.

I can't explain this kind of thing too clearly in the letter, and I can only rely on interviews.

So Dikao came to Hesler again half a month later.

…………

"How many?" Dikao was a little surprised when he heard Netiya's words.

"It's almost eight hundred kilometers." Niteya answered again.

"Damn! Are you so awesome?" Dikao looked excited, "I thought it would be great if you did the first time you did it in Hesler..."

"Dear, it's not the time to praise her?" Selena sat in the chair. "The problem has not been solved yet."

"That's it!" Needia didn't care about Dikao's praise at all. She heard this kind of praise from childhood to adulthood and took a lollipop and put it in her mouth. "The problem now is how to increase the distance. You proposed this thing. Do you have any ideas?"

"The key is..." Dikao was a little stunned at the huge telegraph machine in the living room, "Can you make it smaller?"

"That requires a lot of experiments in the future, not the most important thing," said Nitia. "The first priority now is to increase the transmission distance. Do you have any ideas?"

"Uh, this..." Dikao thought for a while, "There are probably two ways to say something, either bury the wires underground and connect them to me..."

"Impossible, this is not something that can be done secretly." Niteya raised her hand to reject it, "and the investment cost is too high."

"Or it's just that the signal tower is needed." Dikao picked up a piece of paper and explained, "It's just to add a transit equipment to Yinguang City to expand the distance."
