Combined, these two should be able to make unrelayed communication reach about 100 kilometers, which can basically cover most of the residential areas in the western realm, and can also allow Neverwinter to obtain the battle situation on the defense line of the desperate mountains at any time.

If you want to extend it any further, you have to use a signal amplification device.

The reason why Roland chose to develop the corded telephone was that, in addition to Anna's words that aroused his ambitions, the telephone itself was indeed a very versatile tool, whether it was to control the political situation, strengthen the centralization of power, or help the command of the war.

And, more crucially, Neverwinter's current industrial projects have reached saturation.

The four giant industries of civil engineering, mineral smelting, mechanical processing, and chemical production already account for more than ninety percent of the qualified workers, and with their proper size and projected size, it will not be difficult to swallow up the 60,000 or 70,000 new entrants to the West.

Since these industries are closely related to the future war, no one can suffer the Big Four. The most typical is the bicycle factory, which Roland originally built with great interest, and has produced more than enough bicycles for the First Army. When the power is low, it must be the first to shut down, and when there is a shortage of manpower, all the workers have to go to the steam engine factory to work overtime, which can be described as a bad fate.

Even after the construction of the Kingdom Avenue and Highway 67, most of them were horse-drawn carriages - they all came from Changge District or other cities, because there were no horses in the border areas, and there were no stables and other supporting facilities. Seeing that the railroad tracks have begun to be laid, the scene of citizens happily riding bicycles between the two places still does not appear.

Of course, Roland would never admit in front of Barov that this was a mistake in his decision, but now when considering new facilities, he always takes into account the production potential of Neverwinter in advance.

The phone happens to be a great tool that requires little to no production potential and no manual maintenance.

First of all, it will not be put into the civilian market, whether it is military liaison, or connecting the border area and the Changge area, Roland only intends to use a one-to-one way to lay cables. In this way, there is no need for wiring and complex wire networks.

Second, the very small quantities mean that they can be crafted by Anna, Mystery, and Zoroa at their leisure, with little to no appropriation of city productivity.

After the tube is tossed out, it is not too late to vigorously develop civilian communications.

Therefore, the wired telephone is the most suitable project for research and development before the Taqira remnants explore the Daxue Mountain.

......

The development of a prototype telephone went more smoothly than Roland had expected, and by the afternoon two rudimentary magnet telephones had appeared in the backyard of the North Slope Mountain.

It has no shell, and looks like a bare coil and magnet composition, equipped with a hand-cranked generator, and a magnetic battery called the "Aurora Mini". Due to the small amount of power required, the finger-thick magnetic battery can last for at least a month or so, and he does not plan to tinker with the dry battery alone for the time being.

"How do I use this?" Mizuki said curiously, "My ability really has such a magical effect?"

Roland automatically ignored the other party's second half of the sentence, "It's very simple, I'm optimistic...... This hand-cranked motor is responsible for sending out the call signal, and when the user shakes it quickly-" he grabbed the handle and rotated it vigorously, the magnetic bell on the other end suddenly made a "jingling" sound, "at this time, it means that there is a phone access." ”

Then he glanced at Anna, who nodded and picked up the earpiece and microphone.

"When the handset leaves the base, the switch pops up, which means that the voice line is connected and you can talk. The current used to transmit electrical signals is provided by the Dawning Mini, so without the copper rod of the Mystery Moon, the phone can only ring, not transmit. ”

"Uh-huh!" Myzuki puffed up her flat chest and nodded her head twice.

"Your Majesty, can I try to use it to speak?" said Zoroa.

"And me," Suzu held her hand high.

"Of course...... As the makers of it, you are naturally qualified to be the first to experience this epoch-making communication tool. Roland laughed. Needless to say, the significance of the telephone has completely changed the communication habits of human beings, and the distant world is closely linked, and it cannot be overstated, "It's just that the yard is such a short distance, and the signal will hardly be attenuated, just connect it with ordinary copper wires." ”

So in this quiet place surrounded by white jungle, the crisp bell rang constantly. Obviously, you can talk directly, but everyone has to start all over again, starting with hand-cranked power generation.

"There's really a voice!"

"Sounds like Lucia's!"

"Uh, what should I say?"

"Let her guess who you are!"

The witches scrambled to shout at the microphone across the wall, and for a moment, laughter echoed across the courtyard.

Roland also auditioned it twice, and to be honest, the prototype didn't work well, the sound was loud and small, and there was a lot of noise, and it couldn't be considered a good finished product. However, he knew that the next task would be to repeatedly adjust the reed size and the electromagnet spacing, and he would always find the most suitable data for the call.

It didn't take long for the microphone to reach Roland again.

He smiled and shook his head, put the earpiece to his ear, and habitually said, "Hey?"

Except for the faint sound of electric interference, no one answered.

Almost as if he had a heart, he subconsciously guessed the person on the other end of the phone.

"Anna......" Roland said softly.

After a while, a slightly distorted answer was heard.

"I like you...... Rowland. ”

At the end of the day's protection, the nightingale returned to the bedroom somewhat sullenly.

It's not the first time that she can't understand anything, and the only things that comfort her at such times are dried fish and ice cream bread.

Not...... There's one more Chaos Drink now.

Seeing Roland and Anna's intimate appearance, she felt sincere envy and a faint sense of sadness. She thought she would adapt sooner or later, but the process was harder than she thought.

As deep as the affection is, the thorns will grow.

She now understood what Wendy meant.

Walking to the table, Nightingale opened the drawer, only to find the bottle empty.

Did you take the wrong one?

She opened the other drawer again, and it was still an empty bottle.

"Wendy, my Chaos ......" Nightingale was held in her roommate's arms as soon as she turned around, her proud chest almost overwhelming her.

"Nightingale, how many years have we known each other? ”

"yes...... It's been almost four or five years, but my chaos ......"

"We've gone through so many dangers and tribulations along the way to get to where we are today. There's no way anything can ruin our friendship, right?"

"Of course, I've always treated you like half a sister. But my chaos ......"

"I'm sorry I've run out of your drink!" Wendy hugged her tighter, "I'll be sure to make up the draw for you next month!"

Drunk up?

The nightingale touched the empty bag of dried fish.

"The only things that comforted her were dried fish, ice cream bread, and chaos drinks. 」

Now, it's gone.

She heard a cracking sound in her heart.

In an instant, my heart became even more sore.
