Short video spoiler history: The beginning of modern warfare

Chapter 84 Telegraph 2
In front of the Fengtian Palace in Jinling City.

The popular science video on the sky screen was played again, and everyone took advantage of this break to think.

Zhu Yuanzhang felt that using Morse code for encryption was still a bit wrong, because the telegraph had a very wide range. If the Morse code was changed every time to achieve confidentiality, it would cause serious confusion in the code rules.

Moreover, the telegraph will certainly be used in administrative and livelihood fields such as provinces, prefectures, and counties in the future. The confusion of telegraph codes will lead to confusion in information transmission in various places. If local governments act independently, it will be a situation of miscommunication.

The best method is to encrypt based on Morse code. This will not affect the basic information transmission. If encryption is needed, you can agree on it on this basis.

In addition, when sending a telegram, for example, when using Arabic numerals, it is best to leave a few seconds between numbers, otherwise the "." and "—" may be confused and lead to errors in information transmission.

Whether it is Arabic numerals or Chinese characters separated by strokes, it is best to use 4-digit ".", "—" codes to represent them. He would like to use 3 digits unless the combination is not enough.

As for expressing Chinese characters in telegrams, Zhu Yuanzhang thought about it and felt that there were too many Chinese characters. If each number was assigned a telegraph code, it would be extremely unrealistic. With so many characters, it would be impossible to memorize the entire code. Even if there was a table to look up the code, it would not only be very troublesome to look up the code, but it would also be even more troublesome for the receiving party to restore it.

If we use the method suggested by Tianmu to split the characters by strokes, the code of a character will be extremely complicated.
Can we split the word into parts, for example, "好" (good) into "女" (woman) and "子" (son), which seems unreliable?
The reason why it can save trouble is that some radicals of Chinese characters can simplify certain codes. In addition, the characters in later generations are very different from those today, and it seems that many characters have been simplified.
There is also training for telegraph personnel, or we need to let people from the Ministry of Science and the Ministry of Engineering develop an automatic punching machine as soon as possible. There is still a possibility of errors when receiving information manually, so it is best to have 2-3 receivers at the same time to prevent mistakes!
Zhu Yuanzhang wrote furiously, writing down every problem he could think of. These were all things to be discussed.

Tianmu simply shared the principles of the telegraph, but to really implement and utilize these technologies, there are really many supporting things, and there will be even more when they are actually implemented. These problems can only be solved when the time comes. Even if Zhu Yuanzhang sits here and thinks about it for a long time, he may not be able to figure it out.

Zhu Yuanzhang also vaguely realized that the advancement of skylight technology would cause some people to lose their original jobs and their livelihoods, but at the same time it would also create some jobs.

But overall, it is always moving towards mechanization and automation, and this relay is one example.

If there were no relays, the only thing Zhu Yuanzhang could think of was to set up a telegraph operator to forward telegrams every 100 kilometers.

Zhu Yuanzhang didn't know whether this direction was correct. This kind of evolutionary direction would eventually lead to robots and AI.

Kicking ass with a machine is indeed very good, but it may also lead to unemployment among the civilian population. An increase in the number of unemployed people may trigger a series of bad things, which is something he had never thought of before.

During the Zhenguan period, Chang'an City.

Fang Xuanling was amazed. He knew all the knowledge here. He thought electricity was just electricity and could only be used as energy to drive machines. He didn't expect that such an amazing effect could be achieved by simply closing and opening a switch!
From Jinling to Youzhou, communication in seconds!

One hour is equal to two hours in later times. One hour is sixty minutes, and one minute is sixty seconds.

You know, even if there was an urgent report of a war at the front, it would still take 3-5 days to travel along the official road post station, changing people and horses and running quickly.

The efficiency is a world of difference.

And the cost of maintaining this wire is much less than maintaining a post station.
Fang Xuanling looked left and right and was extremely delighted.

With the telegraph, the imperial court's control over local areas will be enhanced to an unprecedented level.

Especially in border wars, information is particularly important. With this fast communication channel, a country's war support capabilities will be raised to a terrifying level.

Everyone can understand all these things without going into details. Although this technology was eventually eliminated, its simple principle is still very advanced for the Tang Dynasty today.

"Do you understand the principle of the relay?" someone was discussing, because the previous parts of the explanation had corresponding animation demonstrations, but the relay mentioned at the end was the only thing that made people confused.

"This is also simple. It is to generate electricity every 100 kilometers. Every 100 kilometers is an independent wire. The wires will be wrapped around metal rods at the intersection of every 100 kilometers. When the current passes through this part of the wrapped wire, a magnetic field will be generated."

"Then turn off the switch and use the circuit to temporarily close when sending a message. When the current passes through the entangled wires, it will form a magnetic field, which will attract the switch of the second independent wire to close." Minister of Works Duan Lun stroked his beard and said, but he was stunned when he saw everyone's increasingly confused expressions.

".?.?"

Duan Lun looked at the clear yet stupid eyes of his colleagues and felt helpless. He had to pick up a pen and draw it on paper. The drawing was quickly circulated and most people finally understood it.

"That's wonderful!"

"It is equivalent to setting up a new radio operator every 100 kilometers, and having this radio operator forward the message. However, this part of the work is automatically achieved by the younger generation using the electromagnetism phenomenon." The people from the Science Department slapped their heads as they suddenly realized something. They were really ashamed that they needed the guidance of the people from the Engineering Department to understand Tianmu's casual words.

"What on earth did these young people come up with?"

“What a fantastic idea!”

"All the knowledge is already known, but I never thought that combining them could achieve such a magical effect!"

Now that Chang'an City has been baptized by the Sky Curtain, they have seen very magical things like electricity, so they naturally know its value. No wonder the young people in the Sky Curtain are full of confidence every time they mention time travel. Li Shimin was very happy. If he were to travel to the Qin and Han dynasties now, he might also look at primitive people with the eyes of a modern person.

There is no way. I am the man who can call the wind and rain and control thunder and lightning. From now on, there is no need to ask Thunder God to help me. Zhang Jiao has to call me "Sir" when he sees me!
To those who don't understand, the various truths in it are no different from miracles.

Immortal? Although I am not one, my methods are not much different.

"Tianmu said that this technology once shone brightly in the history of human development. Why would such a good technology be eliminated?"

"Although this technology is good, it is still much worse than the telephone. The telephone can enable us to talk and chat with people thousands of miles away!" Duan Lun said seriously. The telephone is also the technology he has always been thinking about. Unfortunately, Tianmu did not mention it.

"One must eat one bite at a time. Now that I have acquired this magical skill, what I need to do is to understand and digest all this knowledge. A journey of a thousand miles begins with a single step." Li Shimin said. He knew that although the telegraph was eliminated by later generations, it was still of great significance to the Tang Dynasty.

Its future status will definitely not be low!
"Your Majesty, Holy Might!"

The video was replayed on Tianmu, and everyone followed suit to look at the comments section, from which they roughly learned that this technology is almost lost. According to the discussions of these young people, they searched the Internet and Baidu for a long time but could not find the corresponding principle.

"The name Baidu contains the word 'du'. Is it the Baidu mentioned earlier?" Li Shimin frowned and said.

"I'm afraid so. Someone mentioned before that you can find everything that Tmall Genie knows on Baidu!" Du Ruhui analyzed carefully. "From the comments here, it can be seen that Baidu is probably similar to Hongwenguan, which is mainly responsible for collecting various knowledge and classics."

Li Shimin and others nodded. This analysis was indeed correct and not much different from the image of Tmall Genie who "knows everything about astronomy and geography". However, they did not expect that people in later generations had made many improvements. If they wanted to find something, they no longer had to bury themselves in piles of old papers. They only had to ask and the Tmall Genie would give them the sweet answer.

"What is the net mentioned here?"

"Is it a fishing net? Is there any connection between this and Hongwenguan?"

The ministers were all confused. These names were better than Tmall Genie and Baidu, but they still couldn't guess anything based on the names.

It is also possible that the name is very vivid, but no one has ever seen it and cannot imagine it, just like honeycomb briquettes before.

"The name is not important, the principle is what's important. If you want to find something, just ask it and it will appear out of thin air in a flash."

"It's really a magic trick!"

"Anyway, the function of this website is almost the same as Baidu and Tmall Genie. I don't understand the specific principle yet. I will worry about it when I have the chance."

Everyone nodded, and saw the screen switch the content several times in succession, including a video of someone pulling bananas, repairing donkey hooves, washing carpets, and eating pig trotters live. Finally, it stopped at a video of several young and beautiful geishas with long white legs.

These young women have very different temperaments from the geisha women in Heiankangfang. Their makeup is more delicate, their skin is whiter, and their behavior is more daring. Although their dancing is a bit coquettish, their skin is as delicate as a baby's and their eyes are as charming as silk.

Naked seduction!
Li Shimin had some rare leisure time, and began to tap his fingers to the dynamic rhythm.

The courtyard of Pingkangfang is full of spring.

The madam Chen's eyes lit up. The skin of the woman here was as crystal clear as jade. It would be a shame if she didn't become her daughter.

There is also this form of performance, called a girl group, which was the welcome video for some Winter Olympics ten years ago.

Although it was inappropriate, Mother Chen saw something. With such long legs and white flesh, which lecherous man could resist it? Looking at her 'darlings', she wondered why not try to form a girl group?
In Chun Manting, some people are making their plans as they wish, some are eager to try, but girls like Gan Tang and Qingsha are sitting on pins and needles. They naturally know what Mama-san is thinking and they wish they could find a crack in the ground to crawl into.

It is said that I am selling my art but not my body, but I am living under someone else's roof. Once I step into this vortex, how can I easily get out?

Fortunately, the sky curtain did not stay here for long. After that, it was the "Internet Depression Cloud" time. Only during this time every month could Gan Tang and others calm down and listen to the songs of later generations. At the same time, they also knew that the sky curtain was about to end when it was lit up this time.

Jinling City, in front of Fengtian Palace.

A group of people have begun to pack up and organize today's content. After the skylight goes out, it will be the court meeting, during which various contents need to be sorted and organized for publication.

At the same time, any areas of disagreement need to be discussed, and the manufacturing objects for the next month should be allocated, which is mainly the work of the Ministry of Industry.

The most important content this time is the telegraph. However, the telegraph does not require advanced technical skills like airplanes and steam locomotives. Basically, all you need is hands.

And this thing will profoundly reshape the Ming Dynasty, this is an obvious thing. It is very similar to the telephone in later generations, that is modern society!
According to the calculation of later generations, it is now the 14th century, and other places are still fighting with cold weapons. A modern country will rise slowly.
Daming is about to become the only true god on the blue planet!
