Chapter 742

The combination of these two should enable the non-relay communication to reach about 100 kilometers, which can basically cover most of the residential areas in the western region, and also allow Neverwinter to obtain the battle situation on the defense line of the impenetrable mountains at any time.

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

The reason why Roland chose to develop a wired phone was that apart from what Anna said aroused his ambition, the phone itself is indeed a very versatile tool, whether it is controlling the political situation, strengthening centralization, or directing wars. help is of great importance.

Another more critical point is that the current industrial projects in Neverwinter City have reached saturation.

Newly arrived immigrants need primary education before they can digest them. The four giant industries of civil engineering, mineral smelting, mechanical processing, and chemical production have already occupied more than 90% of qualified workers. In terms of scale, it would not be difficult to swallow the 60,000 to 70,000 newcomers to the Western Territory in one go.

Since these industries are closely related to future wars, no one can suffer from the Big Four. The most typical one is the bicycle factory, which was built by Roland at the beginning with enthusiasm, but the bicycles produced so far are not enough for the first army. When the power is insufficient, it must be the first one to shut down. When the manpower is in short supply, all workers have to go to the steam engine factory to work overtime.

Even if the Kingdom Avenue and Highway 67 are built, the horses and carriages running on the roads are basically from Changge District or other cities, because the border area does not raise horses, and there are no supporting facilities such as stables. Seeing that the railway tracks have started to be laid, the scene of citizens happily riding bicycles between the two places has not yet appeared.

Of course, Roland would never admit in front of Barov that this was his decision-making error, but now when considering new facilities, he will always take Neverwinter's production potential into consideration in advance.

And the phone happens to be a great tool that takes up little production potential and requires no human 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 method to lay cables. In this way, both the wiring process and the complicated wire network need not be erected.

Secondly, the very small quantity means that it can be crafted by Ana, Mystery Moon, and Soraya in their spare time, with little need to divert city productivity.

It will not be too late to vigorously develop civilian communications after the electronic tubes are tossed out.

Therefore, the wired telephone is considered to be the most suitable item for research and development before exploring the Daxue Mountain with the Taquila survivors.

...

The development of the telephone prototype went smoother than Roland expected. In the afternoon, two simple magnet telephones appeared in the backyard of the North Slope Mountain.

It has no casing and looks like a combination of exposed coils and magnets. It is equipped with a hand-cranked generator and a magnetic induction battery. Since the power requirement is not large, the finger-thick magnetic induction battery can last for at least a month, and he does not plan to fiddle with dry batteries alone for the time being.

"How do I use this?" Mystery Moon asked curiously, "My ability really has such a miraculous effect?"

Roland automatically ignored the second half of the other party's sentence, "It's very simple, watch it... This hand crank motor is responsible for sending out the call signal. When the user shakes it quickly," he grabbed the handle and rotated it vigorously, and the magnetic bell on the other end immediately sounded. "Ding Ding Dang Dang" voice, "At this time, it means that there is a call connected."

Then he winked at Anna, who nodded and picked up the receiver and receiver.

"When the handset is off the base, the switch pops up, which means the voice line is connected, and you can talk at this time. The current to transmit the electrical signal is provided by the Dawn Mini, so there is no copper rod from Mystery Moon, the phone is It can only ring the bell, but cannot transmit the sound."

"En, um!" Mystery Yue puffed out her flat chest, and nodded her head twice vigorously.

"Your Majesty, can I try using it to speak?" Soraya eagerly asked.

"And me," Bell raised his hand high.

"Of course it's okay... You are its creators, so 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 linked the distant world. It cannot be overstated. Just connect the wires."

So in this quiet place surrounded by white forests, the crisp bells rang continuously. Obviously you can talk directly, but everyone has to do it all over again, starting with the hand crank generator.

"It really has a voice!"

"Sounds like Lucia's!"

"Uh, what should I say?"

"Let her guess who you are!"

Across the fence, the witches scrambled to shout loudly into the microphone. For a while, laughter echoed in both ends of the yard.

Roland also listened to it twice. To be honest, the effect of the prototype is not ideal. The sound fluctuates, and there are too many noises. It cannot be regarded as a qualified finished product. However, he knows that the next job is to repeatedly adjust the size of the reed and the distance between the electromagnets to achieve the best call quality.

Not long after, the microphone was passed to Roland again.

He shook his head with a smile, covered the earpiece to his ear, and said habitually, "Hello?"

And there was no one answering except for the weak electric interference.

Almost like a tacit understanding, he subconsciously guessed the person on the other end of the phone.

"Anna...?" Roland said softly.

After a while, a slightly distorted answer came from there.

"I like you... Roland."

*******************

After finishing the day's protection, Nightingale returned to the bedroom a little glumly.

It was not the first time that she couldn't understand anything. Whenever this happened, the only things that could comfort her were dried fish and ice cream bread.

Hmm... Now there is an extra Chaos Drink.

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

As deep as the relationship is, the thorns will be as long.

Now she somewhat understood the meaning of Wendy's words.

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

Did you take it wrong?

She opened the other drawer, still an empty bottle.

"Wendy? My chaos..." As soon as Nightingale turned around, she was embraced by her roommate. The proud chest almost made her breathless.

"Nightingale, how many years have we known each other? Ever since you left Quinn's house in Silver City, you've been with me."

"Yeah...it's been almost four or five years, but my chaos..."

"We've been through so much danger and hardship along the way to get to where we are today. Nothing can break our friendship, can it?"

"Of course, I have always treated you as half my own sister. But my chaos..."

"I've run out of your drink, sorry!" Wendy hugged her even tighter, "Next month I will definitely refill you with the one I got!"

What? Drunk?

Nightingale touched the empty dried fish bag.

The only things that can comfort her are dried fish, ice cream bread and chaotic drinks.

Now, all gone.

She heard a crackling sound in her heart.

In an instant, my heart became even more sour.
