The principle and production of the phone are very simple...at least for Yunshen.

As an electromagnetic induction device, it is not much more complicated than the power generation model that Xuanhou demonstrated to Scar at the beginning. The design of transmitting magnetic field changes through current, and then vibrating and sounding through the receiving device does not have high requirements for materials. In history, telephones The appearance of the lamp is actually earlier than the electric light.Not to mention Bell's magnet telephone, Edison's charcoal telephone has almost no difficulty for their current level of productivity.As an invention that has been applied to the earth until the 80s of the last century, the accuracy of sound transmission and the stability of long-distance signal transmission of carbon grain microphones made it the preferred choice before they were able to develop modern telecommunication systems.

The production of the telephone itself is not a problem. The principle of the earpiece and the microphone is the same. They can roll out very thin copper sheets, and they are also very experienced in the manufacture of insulating shells. As long as the outer molds submit the drawings to the carpentry brigade, they can get fine details. The finished products include copper-clad laminates and the simple wiring required for the dial does not need to be acid-etched, and can be completed by hand-cutting, and the electric bell is the fastest solution when imitating mechanical clocks and watches.As long as these parts are assembled, an old-fashioned telephone not far from Yun Shen's memory will be formed. Born in a high-tech family, he has always been deeply impressed by these old objects.

The real difficulty is the manufacture of automatic switches.

Of course, switches can also be bought in Yunshen, but the functions of those modern switches are too "high-end" for them, not to mention the problems of use and failure, so relying on foreign objects will not promote the improvement of the level of the mechanical workshop.As for the three-stage switches of common power, step-by-step, and vertical and horizontal switches, Yunshen also skipped the first two and directly entered the development of vertical and horizontal automatic switches that can be applied to long-distance automatic switching.

Since the beginning of summer, although the number of members in the mechanical workshop has been increasing, the division of labor has gradually been refined, and the development direction of each group has become clear. Their progress has gone further. Although the system is constructed by the magician, the design is proposed by the magician, the big picture is drawn by the magician, the sample is broken down and explained by the magician, and even the craftsmanship is instructed by the magician... But the magician Teacher is really busy.

Especially after the workshop of the power plant was roughly completed and the equipment was moved in and started to be installed, the focus of the technician's work shifted. Occasionally, the captain of the third brigade came to check on their situation instead of the technician, and they had no choice but to be abused by that .Although the taciturn captain would not change his appearance just because the magician was not around, every time he left, there would always be a group of people trembling and kneeling to make up for their shattered self-confidence.

He is so strong in a place that does not belong to the scope of his authority, is he a human being?

In the entire settlement, the people in the mechanical workshop are probably the most recognizable group. When Boss and the others went to listen, a group of men and women with colorless skin and thick dark circles turned their heads and stared at them silently. , even the werewolves who are used to seeing flesh and blood almost blew the hair on the back of their necks, probably because of the invisible pressure. From the beginning to the end, they just stood at the back of the classroom and listened, not to mention that there was really no room to squeeze them in—— There are rows of material cabinets next to the wall. In front of each person is not a desk but a workbench. There are vise clamped on the edge of the table. Next to the vise are toolboxes, pens, materials, parts, and stacks of customized notebooks. It was messy to varying degrees, metal shards spread all over the floor, the blackboard was covered with foggy white after overuse, and it was also filled with unidentified images and numbers... All the werewolves voluntarily resigned without persisting for 10 minutes , also missed the later video presentation.

Even if they saw those contents, it would only add more psychological burden to them.

Difficulties, failures, setbacks, of course, are all there, but they are more than this world, than those researchers in Yunshen's history who can only start from the basics and find the right direction after failures, and are restricted by realistic conditions We were lucky many times. After Yunshen took action to solve the most critical material and technical problems, one day when the blizzard and haze had dissipated, in the first room on the left side of the third floor of the teaching building, a group of people Gathered together, the leading black-haired woman picked up the microphone, pressed her finger on the dial, and dialed the number solemnly.

1001.

The bell only rang twice before it was connected.

"Hello, is the magician there?" She asked with an indistinct trill.

A moment later came a smiling answer, "Well, I'm here."

This became the world's first recorded call.

After hanging up the calls of these joyful young people, Yun Shen communicated with power plants, ironworks, arsenals, mines... and other places. When the call with Xuanhou was about to end, that The man hesitated and asked, "Master, these are four-digit numbers... How far do you plan to develop them in the future?"

"I think," Yun Shen said, "in the future, wherever our footsteps go, our voice will be conveyed."

"..." Xuanhou was obviously taken aback.

Next is the radio, Yun Shen thought, but seeing those young people are so happy now, let's talk to them later.

He opened his notebook, created a new document, and started typing on the keyboard after a little thought. The construction and operation of the power plant provided stable electricity, which made his office work much faster, and he completed the general outline soon.Then he stopped, leaned back, and looked at the screen to conceive of supplementary content.

There was a knock on the door at this time.

Yun Shen came back to his senses, "Please come in."

It was the handsome young man he was most familiar with who opened the door and came in. Yun Shen did not blame him for interrupting his work. Instead, he glanced at the clock on the wall with a little guilt, and was secretly relieved when he found that it hadn't timed out. He smiled and said, "What's the matter, isn't today a day off?"

Although Fan Tianlan had fewer vacations than other people in the same position, and he himself never took the initiative to take vacations, there would always be a few times this year.

"There's nothing I want to go." Fan Tianlan said.

So you still come here?Yun Shen put the computer on standby, looked up at the black-haired young man who came to him, "Is there anything you want to do?"

Want to do?Fan Tianlan reached out and pressed his shoulder lightly, and felt the stiffness of the muscles under his hand as expected, "No." Even if there was, he wouldn't tell you.

"...You are still young anyway." Yun Shen said helplessly, "I remember that there are a few people who have a good relationship with you. Even without them, the first dormitory has an activity room, with billiards and chess and so on..." He He stopped, for a young man like Tian Lan with a special background and a super high IQ, the entertainment that the current settlement can provide is not enough for him.

"Or I'll teach you how to play other games?" he said finally.

"Then I play with myself?" Fan Tianlan said flatly.

"..." After being able to promote those kinds of leisure, puzzle and entertainment, Yun Shen became the third player with the highest chess ability here. Firstly, he was not very good at these things, but a few people showed their strength in this aspect. Extraordinary talent.When Tianlan became interested in Go very rarely, Yunshen was quite happy that he could find an activity that could be called an interest. Then the problem came, Tianlan had no opponent.

The others just got started, and Yun Shen's ability soon became insufficient in front of him. Sometimes, in the gap between other people's submission of reports or consulting work, Yun Shen would find that he was sitting on the chessboard under the window sill while waiting. While playing with himself, the speed of the move was fast and stable, as if he hadn't thought about it, but after Yun Shen went over to see it, he found that it was not the case.The chess game is very strict, and the chess moves are very clear, but the styles of the two chess boards are so different that it is impossible to see that this is the result of one person playing alone.

Meravia doesn't touch these matters, and doesn't seem to have much interest in it, so Yun Shen doesn't know if the silver-haired dragon has similar talents, but being too talented may not be a kind of happiness.

Maybe it would be much better if his personality was as cheerful as Meravia's...?

When Yun Shen was thinking this way, the hand on his shoulder increased a little bit, and then he heard Tian Lan say above his head, "Don't talk about me, how long have you been out for a walk?"

Yun Shen got stuck, "Didn't you focus on switches this week? It snowed some time ago..." It was true that they were all indoors, but there was still equipment maintenance in the ironworks, refined copper, etc. As for the improvement of processing technology, the development of basic radio equipment, and the development of winter education and training, he said not very confidently, "Actually, I have enough exercise."

"Is it a sport for work?" Fan Tianlan lowered his head and asked, the ends of his long black braid fell to his chest.

...Young people speak so directly.

"You may not listen." Fan Tianlan put his hand off Yun Shen's shoulder, reached in front of him and closed the lid of the notebook, "Let's start now."

"What?" Yun Shen watched him go to the hanger aside, and took off his down jacket.

"Go out." Fan Tianlan said concisely, "I'll take you to climb the mountain."

"It's almost five o'clock now..."

"Come back in time for dinner." What's more, what he eats is a small stove, and people will rush to make it for him no matter how late it is.

"...Tianlan," Yun Shen stood up while packing his things, "Why do I feel that you seem to be getting more and more impolite recently?"

"yes."

Regardless of whether this young dragon has a little puberty by chance, Yun Shen will never reject him.What's more, he really hasn't gone out for a while, and the contacts between the school and the workshop in the residence are not counted. What kind of damage has been caused, whether their facilities can withstand the test, the construction problems of this season, and the situation of Sasheer and Hekel. If it is not for Fan Tianlan, he may not be able to think of heavy snow. And obstacles, there will be other things.

"The surface of the lake is frozen..." Yun Shen looked at the lake in front of the road, "How thick is the ice layer?"

"You can't stand up to others." Fan Tianlan said.The source of the lake is the big river, and the river does not freeze all year round. Even if the climate here is abnormal, the ice formed by the rapid freezing will not be very thick.

"There's still rime." Yun Shen was a little surprised.They are walking along this reinforced embankment, which was preserved during the demolition of the temporary measures in late spring, because the view and scenery are good, and a few trees were removed from the mountain, which were planted at that time It was too late for the season, but they survived with strong vitality.Now standing by the lake, frost needles are hanging on the not-so-luxury branches, and Kazuki's silver dress is quite beautiful.

Fan Tianlan took a look, "It's done today." Then he continued to walk forward.

Yun Shen suddenly felt like laughing. If there is any shortcoming of this extremely talented young man, it is probably the emotional part.He has no interest in music, and he doesn't pretend to talk to the opposite sex. It seems that no matter whether the food in the cafeteria is good or bad, he never has any objections. Yun Shen asked him to send flowers to the old priest, and he just accepted it as a task. , and then brought him back the last words of the old priest. It is rare that he would invite himself to climb the mountain today, although the time is not right...

They were walking in the direction of the farm, and the farming work had almost stopped. The people who would walk in this direction were basically people from the shipyard construction site. Although they were about to leave work now, they still didn't see anyone on the road.They went a little further, then turned around.

Looking at the snow-covered path in front of him, Yun Shen felt that he probably knew why Tianlan asked him to climb the mountain.

Although the snow is not clear, it is not deep. People have gone up after the heavy snow, and the windless weather has retained their traces. The slope is not steep, and the clouds are deep. It is not difficult to walk, and the rustling sound of snow particles rubbing against each other is heard regularly , Fan Tianlan, who was one step ahead of him, suddenly stopped.

"What's wrong?" Yun Shen asked.

The handsome young man who could make all the opposite sex hold his breath turned sideways and stretched out his hand, "Are you cold?"

Yun Shen took his hand out of the pocket of the down jacket and put it in his palm. Although he was wearing thermal underwear, a wool sweater and a down jacket, while the young man was only wearing a black wool coat, His hands were very warm, "Tianlan, are you wearing a little less?"

"I don't feel much." Fan Tianlan said.His father has rolled in the high-temperature and high-pressure magma sea for 20 years, but he has evolved from a disfigured alien to a super handsome man. Of course, this temperature difference is nothing to him.

The two of them walked hand in hand for half an hour, and together they climbed to the top of the hill next to the settlement.Not to mention Fan Tianlan, this distance only made Yun Shen breathe a little faster. He looked at the flat land extending from his feet to the opposite side in the distance, from the white snow to the clusters of buildings, his eyes turned around, Finally, it landed on the low saplings lined up beside it.The ground has been covered with a thick layer of straw before the snow. Plant ash was cultivated under the seedlings, and then the roots were tightly flocculated with straw. In order to avoid heavy snow pressure, the branches and leaves were also pruned. Although this plant According to the data, they can withstand the low temperature of at least minus [-] degrees, but everything is well prepared.

"If Huckle's climate is stable, we can consider transplanting them there in the future." Yun Shen brushed off the snow, squatted down to check their condition, and then stood up, "Although it depends on their influence on the water and soil here. Adaptability, but if we can start planting on a large scale, our rubber source will be basically guaranteed.”

"There will always be." Fan Tianlan said beside him.

"It is indeed..." Yun Shen looked softly at the Eucommia in the snow, "We still have a long way to go."

"It's enough for you to be optimistic about yourself now." Fan Tianlan said, "Don't overwork... What will I do if you die?"

The sky and the earth seemed to suddenly become brighter for a while, a ray of sunset light came through the clouds in the sky, the snow surface was shining, the air seemed to have a transparent texture under the refraction of various lights, and the ends of Yun Shen's hair were dyed light. Jin, he turned and looked at the speaker.
