Together, they should be able to make a non-repeater communication range of about 100 kilometers, which could basically cover most of the residential areas in the Western Region. It would also allow Neverwinter to know the situation of the Impassable Mountain Range defense line at any time.
If they wanted to extend the range, they would have to use a signal amplification device.
The reason why Roland chose to use a landline phone was not only that Anna's words had aroused his ambition, but also that the telephone itself was indeed a very versatile tool. Whether it was to control the political situation, strengthen the centralization of power, or help in commanding a war, it was of great significance.
Another more important point was that the current industrial projects in Neverwinter had reached a saturation point.
The new immigrants needed to go through primary education before they could be absorbed. The four giant industries, civil construction, mineral smelting, mechanical processing, and chemical production, had already occupied more than 90% of the qualified workers. Judging from their size and estimated scale, it would not be difficult for them to swallow up the 60,000 to 70,000 new immigrants in the Western Region.
Since these industries were closely related to the future war, no one could suffer but the four giants. The most typical example was the bicycle factory, which Roland had built in high spirits at the beginning, but the number of bicycles produced so far was not even enough for the First Army. When there was a shortage of power, it would be the first to shut down. When there was a shortage of manpower, all the workers had to go to the steam engine factory to work overtime, which could be said to be a difficult life.
Even after the Kingdom Avenue and Route 67 were built, the roads were basically filled with horse-drawn carriages from the Longsong Area or other cities, because the Border Area did not raise horses, nor did it have supporting facilities such as stables. Even though the railway had begun to be laid, the scene of citizens happily riding bicycles between the two places still did not appear.
Of course, Roland would never admit to Barov that it was his mistake. But now, when he was considering new facilities, he would first take into account the production potential of Neverwinter.
The telephone happened to be a good tool that didn't require any production potential, and it didn't require manual maintenance.
First of all, it would not be put into the civilian market. Whether it was for military communication or to connect the Border Area and the Longsong Area, Roland only planned to use a one-to-one method to lay the cable. In this way, the wiring process could be saved, and there was no need to set up a complicated network.
Second, the small number of telephones meant that Anna, Mystery Moon, and Soroya could make them in their spare time, and there was almost no need to use the city's production capacity.
It wouldn't be too late to develop civilian communications after the electron tube was invented.
Therefore, the wired phone was the most suitable project to research before the Taquila survivors explored the Great Snow Mountain.
…
The development of the telephone prototype was smoother than Roland had expected. In the afternoon, two simple magnetic telephones appeared in the backyard of North Slope Mountain.
It didn't have a shell and looked like a combination of naked coils and magnets. It was equipped with a hand-cranked motor and a magnetic induction battery, "Mini Dawn." Since he didn't need a lot of power, the finger-thick magnetic battery could last for at least a month, so he didn't plan to work on a dry battery alone for the time being.
"How do I use this?" Mystery Moon asked curiously. "Is my ability really so magical?"
Roland automatically ignored the latter half of the other party's sentence. "It's very simple. Look carefully … this hand-cranked motor is responsible for the call signal. When the user shakes it," he grabbed the handle and turned it hard, and the magnetic bell on the other end suddenly made a "ding ding dang dang" sound. "At this time, it means that there is a call."
Then he winked at Anna, who nodded and picked up the handset and the microphone.
"When the handset leaves the base, the switch pops up, which means that the voice line is connected, and then we can talk. The electric current for the transmission of the electric signal is provided by the Mini Dawn, so without Mystery Moon's copper rod, the phone can only ring but not transmit sound. "
"Yes, yes!" Mystery Moon stuck out her flat chest and nodded hard twice.
"Your Majesty, can I try to use it to speak?" Soroya asked eagerly.
"Me too." Bell raised her hand high.
"Of course, no problem … As its creator, you are naturally qualified to be the first to experience this epoch-making communication tool," Roland said with a smile. There was no need to explain the significance of the telephone. It had completely changed human communication habits and closely connected the distant world. It was not an exaggeration to praise it too much. "But the yard is so short, and the signal will hardly be attenuated. Just connect it with ordinary copper wire."
Therefore, in this quiet place surrounded by the white forest, the crisp sound of the bell rang continuously. They could have talked directly, but everyone insisted on starting from scratch, starting from the handheld flashlight.
"There's really a sound!"
"It sounds like Lucia's!"
"Uh, what should I say?"
"Let her guess who you are!"
Separated by the wall, the witches scrambled to shout into the microphone. For a moment, the sound of laughter echoed from both ends of the yard.
Roland also tried it twice. To be honest, the prototype was not ideal. The sound was sometimes loud and sometimes soft, and there was a lot of noise. It could not be regarded as a qualified finished product. But he knew that the next step was to repeatedly adjust the size of the reed and the distance between the electromagnets to reach the best quality.
Not long after, the handset was passed to Roland again.
He smiled and shook his head, put the handset to his ear, and habitually said, "Hello?"
But there was no reply except for the faint sound of the electric current.
Almost as if their hearts were connected, he subconsciously guessed the person on the other side of the phone.
"Anna …?" Roland said softly.
After a while, a slightly distorted answer came from the other side.
"I like you … Roland."
After a day of protection, Nightingale went back to her bedroom, a little depressed.
This was not the first time she felt like she did not understand anything. Every time this happened, the only thing that could comfort her was dried fish and ice cream bread.
Well … now there was one more Chaos Drink.
Seeing the intimacy between Roland and Anna, she felt a heartfelt envy, as well as a faint sense of sadness. She thought she would get used to it sooner or later, but the process was harder than she thought.
The deeper the relationship, the longer the thorns would be.
She now somewhat understood the meaning of Wendy's words.
Walking to the table, Nightingale opened the drawer, but found that the bottle was empty.
Did she take the wrong one?
She opened the other drawer, and there was still an empty bottle.
"Vendy? My Chaos Drink … "As soon as Nightingale turned around, she was hugged by her roommate. That proud chest almost made her breathless.
"Nightingale, how long have we known each other? Ever since you left the Quinn family in Silver City, we've been together, right? "
"Yes … it's been almost four or five years, but my Chaos Drink …"
"We've experienced so many dangers and hardships along the way to get to where we are today. Nothing can destroy the friendship between us, right? "
"Of course, I've always treated you as half a sister. But my Chaos Drink … "
"I finished your drink, sorry!" Vendy hugged her tighter. "I'll make it up to you next month!"
What? Finished it?
Nightingale touched the empty bag of dried fish.
The only thing that could comfort her was dried fish, ice cream bread, and Chaos Drink. "
Now, it was all gone.
She heard a cracking sound in her heart.
