The combination of these two should enable the unrelayed communication to reach about 100 kilometers, which can basically cover most of the residential areas in the Western Territory, and also allow Neverwinter City to obtain the battle situation on the defense line of the desperate mountains at any time.
If you want to extend it further, you must use a signal amplifier.
The reason why Roland chose to develop a wired telephone was not only that Anna's words had aroused his ambition, but the telephone itself was indeed a very versatile tool, whether it was controlling the political situation, strengthening the centralization of power, or commanding the war. help is significant.
Another more critical point is that the current industrial projects in Neverwinter City have reached saturation.
New immigrants need to go through primary education to be digested. The four giant industries of civil construction, mineral smelting, mechanical processing and chemical production already occupy more than 90% of qualified workers. In terms of scale, it is not difficult to swallow the 60,000 to 70,000 people who have newly joined the Western Territory.
Since these industries are closely related to future wars, no one can suffer the Big Four. The most typical example is the bicycle factory. This factory that Roland built with enthusiasm at first has not produced enough bicycles to qualify for the First Army. When the power is insufficient, it must be the first to shut down. When there is a shortage of manpower, all workers have to go to the steam engine factory to work overtime.
Even if Kingdom Avenue and Route 67 are built, horses and carts are basically running on the road—they all come from Changge District or other cities, because the border areas do not keep horses, nor do they have supporting facilities such as stables. Seeing that the railway tracks have been laid, the scene of the citizens riding bicycles to and fro between the two places still did not appear.
Of course, Roland would never admit that this was his decision-making mistake in front of Barov, but when considering new facilities now, he would take the production potential of Neverwinter into consideration in advance.
And 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 for military liaison or connecting the border area and the Changge area, Roland only intends to use a one-to-one method to lay cables. In this way, the wiring process is omitted, and there is no need to set up a complex wire network.
Second, the very small number means it can be crafted by Ana, Mystery Moon, and Soraya in their spare time, with little need to divert city productivity.
It is not too late to vigorously develop civil communication after the electronic tube is tossed out.
Therefore, the wired telephone is the most suitable project for research and development in cooperation with the Taquila survivors to explore the front of the Daxue Mountain.
…
The development of the phone prototype went more smoothly than Roland expected. By the afternoon, two simple magnet phones appeared in the backyard of Beipo Mountain.
It has no outer casing and looks like a combination of exposed coils and magnets, equipped with a hand-cranked generator, and a magnetic induction battery "Dawning Mini". Since the power required is not large, the magnetic induction battery with the thickness of a finger can last at least a month or so, and he does not intend to fiddle with the dry battery alone for the time being.
"How do I use this?" Miyue asked curiously, "My ability really has such a magical effect?"
Roland automatically ignored the second half of the other party's sentence, "It's very simple, look at it... This hand-cranked motor is responsible for sending out the call signal, when the user shakes it quickly—" He grabbed the handle and turned it hard, and the magnetic bell on the other end suddenly sounded The sound of "ding ding ding dong", "At this time, it means that there is a phone call."
Then he winked at Anna, who nodded and picked up the receiver and microphone.
"When the receiver leaves the base, the switch pops up, which means that the voice line is connected, and the conversation can be made at this time. The current that transmits the electrical signal is provided by the Dawning Mini, so there is no copper rod of Mystery Moon, the telephone is It can only ring the bell, not the sound."
"Hmm, um!" Miyue raised her flat chest and nodded her head vigorously.
"Your Majesty, can I try to use it to speak?" Soraya asked eagerly.
"And me," Bell raised her hand high.
"Of course no problem... You are its makers, and you are naturally qualified to experience this epoch-making communication tool first." Roland laughed. Needless to say, the significance of the telephone has completely changed the communication habits of human beings, and it has closely connected the distant world. It is impossible to exaggerate it. "It's just that the yard is so short that the signal will hardly be attenuated. Just connect the wires."
So in this quiet place surrounded by white jungle, the crisp bells kept ringing. Obviously you can talk directly, but everyone has to start all over again, starting with the hand-cranked power generation.
"It really has a voice!"
"Sounds like Lucia's!"
"Uh, what should I say?"
"Let her guess who you are!"
The witches scrambled to shout into the microphone across the fence, and for a while, laughter and laughter echoed across the yard.
Roland also listened to it twice. To be honest, the effect of the prototype is not ideal. The sound is loud and quiet, and there are too many noises. It cannot be regarded as a qualified finished product. However, he knows that the next work only needs to repeatedly adjust the size of the reed and the distance between the electromagnets to achieve the best call quality.
It didn't take long for the microphone to reach Roland again.
He smiled and shook his head, put the receiver to his ear, and said habitually, "Hello?"
And apart from the faint sound of current interference, no one answered.
Almost like a consonance, he subconsciously guessed the person on the other end of the phone.
"Anna...?" Roland whispered.
After a while, a slightly distorted answer came from there.
"I like you... Roland."
*****************
After a day of protection, Nightingale returned to her bedroom a little gloomy.
It wasn't the first time that she couldn't understand anything. Whenever it happened, the only people who could comfort her were dried fish and ice cream bread.
Hmm... Now there's one more Chaos drink.
Seeing the closeness between Roland and Anna, she felt heartfelt envy and a constant sense of sadness. She thought she would get used to it sooner or later, but the process was more difficult than she imagined.
How deep the feelings are, how long the thorns are.
She now somewhat understood what Wendy meant.
Walking to the table, Nightingale opened the drawer, only to find that the bottle was empty.
Did you get it wrong
She opened the other drawer, still an empty bottle.
"Wendy? My Chaos..." Nightingale just turned around when she was hugged by her roommate, her proud chest almost made her breathless.
"Nightingale, how many years have we known each other? You have been with me since you left Quinn's house in Silverlight City."
"Yeah... It's been almost four or five years, but my chaos..."
"How much danger and tribulation we've gone through to get to where we are today. Nothing can destroy our friendship, right?"
"Of course, I've always regarded you as a half-sister. But my chaos..."
"I've run out of your drink, sorry!" Wendy hugged her tighter, "I'll definitely supply you with the one I've drawn next month!"
What? Drink up
Nightingale touched the empty dried fish bag.
"The only things that can comfort her are dried fish, ice cream bread, and Chaos Drink."
Now, there are none.
She heard a cracking sound in her heart.
In an instant, my heart became more sour.
