Release that Witch Chapter 742: The other side of the relationship

Together, the two should enable non-relay communication to reach about 100 kilometers, which can basically cover most residential areas of Western Region's, and also allow Neverwinter City to obtain the situation on the Impassable Mountains defense line at any time.

To extend it further, you must use a signal amplifier.

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

Another more important point is that Neverwinter City's current industrial projects have reached saturation.

The new immigrants can only be digested after primary education. Civil engineering, mineral smelting, mechanical processing, and chemical production, the four giant industries, have occupied more than 90% of the qualified workers. In terms of volume and estimated scale, it is not difficult to swallow the new joining Western Region's sixty-seven thousand people in one mouthful.

Because these industries are closely related to future wars, no one can suffer the Big Four. The most typical one is Bicycle Factory. This Roland factory was originally built with enthusiasm. The bikes produced so far are not enough for First Army points. When the power is insufficient, the first shutdown must be it. When there is a shortage of staff, all workers have to go to Steam Engine Factory to work overtime, which can be described as life-threatening.

Even if the Kingdom Highway and Route 67 are built, the carriages on the roads are basically carriages --. They also come from Longsong region or other cities, because the border area does not have horses and there are no supporting facilities such as stables. Seeing that the railroad tracks had begun to be laid, the scene of citizens riding bicycles to and fro between the two places still did not appear.

Of course, Roland will never admit to Barov that this was a decision error, but now when considering new facilities, he will take into account the production potential of Neverwinter City in advance.

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

First of all, it will not enter the civilian market. Whether it is military liaison or connecting the border area with Longsong region, Roland only intends to use one-to-one method to lay cables. In this way, not only the wiring process is omitted, but also no complicated wire network needs to be set up.

Second, the small number means that it can be produced by Anna, Mystery Moon, and Soraya in the free time, and there is almost no need to divert urban productivity.

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

Therefore, the wired telephone is the most suitable research and development project before exploring Great Snow Mountain in conjunction with Taqila survivor.

...

The development of the phone prototype went more smoothly than expected by Roland. By the afternoon, two humble magnet phones appeared in the Northern Slope Mountain backyard.

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 "Shuguang Mini". Because the amount of electricity required is not large, the magnetic sensor battery with the thickness of a finger can last at least a month or so, and he does not plan to tinker with the battery alone for the time being.

"How do I use this?" Mystery Moon curiously, "Is my ability really such a magical effect?"

Roland automatically ignores the second half of the other party ’s words, “It ’s very simple, optimistic ... This hand-cranked motor is responsible for sending out the call signal. When the user quickly shakes it, --.” He grasped the handle and turned it strongly, The magnetic bell suddenly sounded "Ding-Dang-Dang", "At this time, it means that there is a phone connection."

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

"When the handset leaves the base, the switch pops up, which means that the voice line is connected, and you can talk now. The electric signal transmission current is provided by Shuguang Mini, so there is no copper rod of Mystery Moon, The phone can only ring, it cannot make a sound. "

"Yeah, Yeah!" Mystery Moon lifted his flat chest and nodded hard.

"Your Majesty, can I try to use it to talk?" Soraya eagerly tried.

"me too," Ling Gao raised his hand high.

"Of course no problem ... you are the creators of it, and you are naturally qualified to experience this landmark communication tool first." Roland laughed. The meaning of the phone need not be said much. It has completely changed the communication habits of human beings and closely connected the distant world. It is no exaggeration to praise. "It is just such a short distance in the yard that the signal will hardly be attenuated. Ordinary copper Line is connected to then it will be alright. "

So in this quiet place surrounded by white forest, a crisp ringing bell keeps ringing. Obviously you can talk directly, but everyone has to start over again, starting with manual power generation.

"I really have a voice!"

"Sounds like Lucia!"

"Uh, what should I say?"

"Let her guess who you are!"

witches yelled loudly into the microphone across the wall. For a time, laughter echoed across the yard.

Roland also auditioned twice. To be honest, the effect of the model machine is not ideal, the sound is loud and loud, and there is a lot of noise, and it cannot be regarded as a qualified finished product. However, he knew that the next work only needed to repeatedly adjust the reed size 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 shook his head with a smile, covered the earpiece with his ear, and said habitually, "Hello?"

No one answered, except for the weak current interference.

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

"Anna ...?" Roland whispered softly.

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

"I like you ... Roland."

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

After finishing the day of protection, Nightingale returned to the bedroom glumly.

It's not the first time that I can't understand anything. Whenever this time, only dried fish and ice cream bread can comfort her.

Well ... now there is one more Chaos Drink.

Seeing the intimate looks of Roland and Anna, she felt heartfelt envy and a lingering sadness. I thought she would get used to it sooner or later, but the process was more difficult than she thought.

As long as the feelings are, the thorns grow.

She now understands the meaning of Wendy.

Walking to the table, Nightingale opened the drawer, but found that the bottle was empty.

Is it wrong?

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

"Wendy? My Chaos ..." Nightingale turned around and was hugged by her roommate. Her proud chest almost made her breathless.

"Nightingale, how many years have we known? Since you left Quinn Family of Silver Light City, you have been with me."

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

"How many dangers and tribulations we have experienced along the way, we have only reached this step today. Anything impossible destroys our friendship, right?"

"Of course, I always treat you as a half sister. But my chaos ..."

"I've run out of your drink, sorry!" Wendy squeezed her tighter, "I will definitely replenish the one I got next month!"

What? Drink up?

Nightingale touched the empty dried fish bag.

"Only dried fish, ice cream bread and Chaos Drink can comfort her."

Now it's gone.

She heard a crackling sound in her heart.

In a moment, my heart was more sour.
