Wang Yan stepped forward, and saw that there were introductions below the hanging things, it turned out that this was a masterpiece selected by the elytra of the Seven Gods internally, and it was generally selected once every six months, this laser cannon was a product of more than ten years ago, and it is estimated that it has already completed the production and assembly into the army.

"Is it an order from Her Royal Highness? Of course, I will follow the wishes of Her Royal Highness. After learning about the intention of Wang Yan and others, the person in charge quickly agreed to find a few scientists who had studied communications, and Wang Yan and the four of them only sat in the hall for a few minutes, and the scientists who rushed to hear the news arrived.

"Where, where are the people who know a lot about telecommunications?"

"It's him, he's too young, so small, as big as my assistant, what can he do?"

"It can't be a liar, right?"

The three scientists who arrived were all wearing thick glasses, and after they communicated with the person in charge, they all looked at Wang Yan suspiciously, not knowing what the origin of this young man was, and he could actually be admired by Her Royal Highness.

"Let's go straight to the lab." Wang Yan understood that it was useless to say anything, and they had to be truly convinced by the principle of long-distance communication.

In the laboratory, Wang Yan saw the most cutting-edge communication equipment in the world today, observed for a moment and listened to the person next to him explain the principle, Wang Yan couldn't help laughing, it turned out to be a telegraph.

"What are you laughing at, have you ever seen a telegraph that can send pictures?" The other party pulled out a stack of things, and after putting it down, Wang Yan could see that it was some pictures of flowers and plants, but they were all black and white.

"Oh, fax, I know." Wang Yan still had that indifferent expression: "Is there any, I just saw a video record in the hall, what kind of video is recorded?" ”

"How can you see that? It's still experimental. The three of them all laughed slightly, Wang Yan shook his head and sighed: "I thought you had a lot of ability, look at this." ”

Wang Yan took out the laptop with his backhand, then clicked on the webpage and selected an issue in Man and Nature, and chose to play it on mute, since Wang Yan took out the thin laptop the size of a diary, the eyes of the three scientists widened, and when the screen of the laptop began to play as if they had seen it with their own eyes, the three of them hurriedly approached the notebook, and one of them looked behind the notebook suspiciously, but did not find anything abnormal.

The picture of the notebook is constantly changing, and when they see a fast-running beast attacking an antelope and biting off its neck to look around, all three of them gasp for breath, too real, really too real!

"Oh my God, where in the Celestial Realm already has such a new technology? You have to tell me where this is the lab that produced the experiment, and I really want to see what it was like to be a great scientist who was able to work on such an amazing experiment. ”

"Hahahaha." Wang Yan laughed, he closed the notebook with his backhand and put it away: "I took this out, just to let you know that what I know is not as little as you imagined, understand?" ”

"Understood, understood." The three of them hurriedly replied, anyone who saw the clear video on the notebook would be shocked, and they couldn't help but wonder, how did they do it?

"I'm here to help you complete remote communication this time, so let's get back to business first, the road has to be taken step by step, sometimes it's not that you can go fast when you take a big step."

"That's right, it does."

"Yes, if the foundation is not laid, it is not a good thing to progress too fast."

The three scientists, who had been thinking with some pride, nodded their heads repeatedly, and now they were completely convinced that the young man would be able to help them with long-distance communication that they had not been able to do for a long time.

Use the strength of the current to simulate the change of sound volume, so as to use the current to transmit the sound, this is the principle of telephone communication, and the telegraph must lay the line is different, the telephone can complete the signal relay through the signal tower, but this requires the support of the satellite.

There are satellites in the sky, but the original use is to set up laser weapons to carry out indiscriminate strikes anywhere on the ground, after years of hard work, the satellite is indeed launched into the sky and into orbit, but the consequences of the crooked technology tree are revealed, and it will take a long time for them to communicate with the satellite.

"The old satellite is not good, and a new satellite must be launched." After discussing with the three of them for a while, Wang Yan said this sentence, after all, if you want to complete long-range communication as soon as possible, satellites must be launched, not to mention unrestricted communication like on the earth, the current communication range of the celestial realm is also 100 kilometers, and a message needs to be transferred several times or even dozens of times to reach the destination, which takes too long and is prone to mistransmission of information.

"Then you need to make a decision at the Council of Nobles before the Institute can start launching, but there are still satellites that have already been built, and you can change and renovate them according to your wishes." The person in charge of the research institute answered, Wang Yan shook his head, it seems that all decisions can only be completed at the noble council the day after tomorrow, and now that they say more, it will be useless if they don't pass it at that time.

However, long-distance communication can not complete the experiment for the time being, Wang Yan feels that it is still possible to start radio communication, although this communication method can only be a few kilometers, but it is convenient, as long as the two communicators are on, there is no need to set the channel to communicate, after all, the current celestial realm, there is not much interference from electromagnetic waves.

"Radio? What is it? ”

"Short distance communication? The institute can also communicate with some places in Dietrie. ”

Listening to the new ideas that came out of Wang Yan's brain, several people were puzzled, Wang Yan had to work hard to explain to him, so he took out his laptop to check the principle of radio communication, after all, he only knew all the skins, and it must be no problem to use, and it was impossible to directly say the manufacturing principle or even make it immediately.

When Wang Yan finally made the three of them understand the principle of radio communication, the three of them were overjoyed and said goodbye to Wang Yan and went to the laboratory to make it, which was nothing more than some magnets and copper wires and then energized, first to make them that could be used and then slowly improved.

"I didn't expect you to be a scientist, Carey." Walking out of the hall of the research institute, Zedin Schneider looked at Wang Yan and became much more respectful, the atmosphere of the heavenly realm has always been like this, and those who can have new scientific and technological research results will quickly get the respect and attention of others.
