Release that Witch

The sum of the two should be able to make the non-relay communication reach about 100 kilometers, which can cover most of the residential areas in the West, and also allow the Winter City to obtain the battle situation on the mountain line.

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

The reason why Roland chose to develop a wired telephone, in addition to Anna’s words aroused his ambition, the phone itself is indeed a very versatile tool, whether it is to control the political situation, strengthen the centralization, or command the war. The help is significant.

Another key point is that the current industrial projects in No Winter City have reached saturation.

New immigrants need to be digested after primary education. The four giant industries of civil engineering, mineral smelting, mechanical processing and chemical production have already occupied more than 90% of qualified workers, and they should have the volume and expectation. In terms of scale, it is no difficulty to swallow the six or seventy-seven people who have joined the West.

Since these industries are closely related to the future war, no one can suffer from the Big Four. The most typical one is the bicycle factory. This Roland plant was originally built with great enthusiasm. The bicycles produced so far are not enough for the first army. When the power is insufficient, the first one must be shut down. When the manpower is in short supply, all the workers have to go to the steam engine factory to work overtime. It can be said that it is a long way to go.

Even if Wang Guo Avenue and Highway 67 were built, the roads were basically horse-drawn carriages – all from the Changge District or other cities, because there were no horses in the Bianbu District, and there were no supporting facilities such as stables. Seeing that the railroad tracks have begun to be laid, the scenes of the citizens who are happy to ride bicycles to and from the two places still do not appear.

Of course, Roland will never admit that this is his decision-making mistake in front of Barov, but now that he considers the new facilities, he will pre-empt the production potential of No Winter City.

The phone is just a good tool that requires almost no production potential and no manual maintenance.

First of all, it will not be put into the civilian market. Whether it is military contact or connecting the border area and the long song area, Roland only intends to use one-to-one methods to lay cables. In this way, the wiring process is eliminated and no complicated wire mesh is required.

Secondly, the very small number means that it can be produced by Anna, Mystery Moon and Soroya at leisure, with little need to divert urban 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 in front of the Daqishan Mountain.

......

The development of the phone prototype was even smoother than Roland expected. In the afternoon, two simple magnet phones appeared in the backyard of the North Hill.

It has no outer casing and looks like a combination of bare coils and magnets. It is equipped with a hand-cranked generator and a magnetic battery called "Twilight Mini". Since the amount of power required is not large, the magnetic battery with a finger thickness can last for at least a month, and he does not intend to dry the battery alone.

“How do you use this?” Mystery Moon curiously, “Is my ability really so amazing?”

Roland automatically ignored the latter half of the sentence. "It's very simple, optimistic... This hand-cranked motor is responsible for sending out the call signal when the user shakes it quickly-" He grabs the handle and rotates hard, the magnetic bell on the other end Suddenly, the voice of "clam dangling" was issued. "At this time, it means there is a telephone access."

Then he gave Anna a look, and the latter nodded and picked up the handset and microphone.

“When the handset leaves the pedestal, the switch pops up, meaning that the voice line is turned on, and you can talk at this time. The current that delivers the electrical signal is provided by the Twilight Mini, so there is no such copper rod for the mystery, the phone is Can only ring, can't pass sound."

"Well, um!" Mystery month stood up on the chest of the tablet and forced it twice.

"Your Majesty, can I try to use it to speak?" Soloya eagerly tried.

"And me," Bell raised his hand high.

"Of course no problem... you are the maker of it, and naturally qualified to take the lead in experiencing this epoch-making communication tool." Roland laughed. Needless to say, the meaning of the telephone has completely changed the communication habits of human beings and closely linked the distant world. It is not an exaggeration to praise. "It’s just a short distance from the yard, the signal will hardly decay, with ordinary copper. The lines are connected."

So in this quiet place surrounded by white bushes, the ringing sounds are constantly ringing. It is obvious that you can talk directly, but everyone has to repeat it, starting with hand-cranked power generation.

"There is really a voice!"

"It sounds like Lucia!"

"Hey, what should I say?"

"Let her guess who you are!"

The witches screamed at the microphone across the wall, and for a time, laughter echoed at the two ends of the yard.

Roland also listened twice. To be honest, the effect of the prototype is not ideal, the sound is too big and small, and there are so many noises that it can't be regarded as a qualified finished product. However, he knows that the next step is to adjust the reed size and the distance between the electromagnets repeatedly to make the call quality the best.

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

He smiled and shook his head, covering the earpiece with his ear, habitually opening the way, "Hey?"

And there was no one to answer except the weak current interference.

Almost a heart, he subconsciously guessed the person on the phone.

"Anna...?" Roland whispered.

After a while, there was a slightly distorted answer.

"I like you... Roland."

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

After finishing the day's protection, the nightingale returned to the bedroom with some sullenness.

It is not the first time that this feeling of incomprehension is not the first time. At this time, only the dried fish and ice cream bread can comfort her.

Uh... There are more chaotic drinks now.

Seeing Roland and Anna's intimate appearance, she felt sincere envy and faint heart. I thought I would adapt sooner or later, but this process is more difficult than she thought.

How deep is the feeling, how long the thorns will be.

She now understands what Wendy is saying.

Going to the table, the nightingale opened the drawer, but found the bottle empty.

Did you get it wrong?

She opened the drawer on the other side and was still an empty bottle.

"Wenty? My chaos..." The nightingale just turned and was held in her arms by her roommate. The proud chest almost made her breathless.

"Night, how many years have we known? Since you left the Quinn family in Silver City, you are with me."

"Yeah... almost four or five years, but my chaos..."

"How many dangers and hardships we have experienced along the way, we have come to this step today. Nothing can destroy the friendship between us, right?"

"Of course, I have always treated you as a half-brother. But my chaos..."

"Your drink, I am drinking, sorry!" Wendy tightened her tightly. "I will definitely replenish the one I received next month!"

what? Drinking it?

The nightingale touched the empty dried fish bag.

"The only thing that can comfort her is dried fish, ice cream bread and chaotic drinks."

Now, there is no more.

She heard a crack in her heart.

In an instant, my heart is more sour.
