After school that day, all the students of this class were pale, and all of them went out with dull eyes.
After suffering for six years, I thought I could finally see the light, but found that what greeted me was a deeper darkness.
Thinking about the next four years, everyone wants to cry but has no tears.
Students from other classes wondered at first that these seniors had been in high spirits recently, why they suddenly looked like they would rather die than live.
After knowing the situation, each of them's face changed tragically.
The future of these seniors is also their future...
Some people would rather die than live, and naturally some people are happy.
Zhan Caixian, for example, likes this place very much.
There are teachers around, and the students are also interesting. They can learn all kinds of interesting things, and they can also go to the library to read interesting comics.
She doesn't like to work in any department, and her family is not short of money. It would be best if she continues to study in this school!
Ten days later, the first batch of students graduated again, but this time the graduation party was much simpler.
But this time, all but one student in the civilian family chose to graduate.
After all, for them and their families, learning to this point is enough. Another four years of study will be too much pressure for them. After all, the family situation of ordinary people cannot support them to keep learning like this.
Nor do they want to.
Now that Dayao is changing, Lancheng and Dayao are different every month. When they were in the academy, they watched all this from the sidelines, and they often had the idea of participating in it.
Therefore, they chose to graduate and enter the six departments.
Ren Baqian also understood this very well.
As for the heirs of those powerful clans, none of the successful ones graduated.
All went to college.
Amidst the wailing, the first thing to greet them was the entrance exam a month later.
…
In the court hall at this moment, the eyes of a group of people were all on a small table in the center.
On the table is a black box with a disc with numbers from 0 to 9 written on it.
And there is a wire on the box, which has been connected to the outside of the hall.
Ren Baqian held the microphone on the box with one hand, and turned the disc with the other, and a beep came out of the microphone after a while.
There was only one ring, and the other end was picked up.
"Your Highness?"
"We succeeded!" Ren Baqian looked at the crowd and laughed.
Before everyone responded, the other end of the phone cheered.
Ren Baqian said a few forgiving words to the other end of the phone, then hung up the phone and looked at everyone in the hall with a smile.
"Your Highness, isn't this the same as the previous radio station?" Shi Qing asked.
Although Ren Baqian didn't explain, they already guessed the purpose of the box.
"No, the radio station is a radio station. The radio station is our conversation in one channel, which belongs to fixed-frequency communication. There are several disadvantages in it. First, the number of fixed-frequency stations is limited, and radio stations cannot be used by everyone.
Second, if other people get the radio, they can hear the conversations on the channel.
Although this has not happened before, it does not mean that it will not happen in the future.
Third, the anti-interference ability of radio stations is weak. For example, in the land of Tianjing, radio stations cannot be used. "
Everyone doesn't understand technology, and they don't understand the meaning of Ren Baqian's words.
It's just that from Ren Baqian's words, it can be heard that this box is something better than a radio station.
"Let me introduce you." The empress sat at the head and said calmly.
"Yes!" Ren Baqian gave the empress a smile.
He turned around and said, "This is a telephone, which is also used for long-distance communication like a wireless station.
There is no need to say more about the others, but only two of them. First, this is point-to-point communication. A phone only needs to dial the corresponding number to communicate with any phone.
For example, this station can make point-to-point calls with any department of the six departments at any time, or any department in any city, and everything that is said can only be heard by the people at the two ends of the phone. "
Everyone nodded, this time everyone understood.
The radio station is for everyone to chat together, but this phone call is for two people to chat in private.
"Second, and most importantly, the popularity of telephones. Telephones can be laid to any place in Dayao, and there can be millions, tens of millions of telephones.
Whether it's every department, every city, or even every family.
Everyone can use a phone to dial the corresponding number and have a conversation with one of these millions of phones.
For example, Mr. Shi can install such a phone in his house.
As long as I have the corresponding number of Mr. Shi's home phone number, I can call Mr. Shi's house from any phone at any time and talk to Mr. Shi.
For example, if you are in any corner of Lancheng, or in any corner of Dayao, even if you are in the 60,000 mountains, you can still contact the mansion by phone. "
After Ren Baqian finished speaking, he smiled and looked at the crowd.
It takes a while for them to react.
Although they had seen enough new things over the years, it still took some time to digest Ren Baqian's words.
On the earth, the early application of the telephone was a magnet-type telephone, which is the kind in the movie that makes a phone call while cranking it by hand, and then transfers it through an operator.
After that, there is a common electric telephone, which no longer needs to be hand-cranked to generate electricity, but it still needs the operator of the telephone exchange to make manual connections.
This kind of telephone needs to be switched manually, so there are not a few numbers, and the number of natural users cannot be large.
Back then, Asia's largest telephone exchange in Shanghai had only a few thousand users.
The biggest limitation on the telephone is not the technology of the telephone, but the technology of telephone interaction.
The above two types are for manual connection, and then the step-by-step switch can already allow the phone to be connected in a mechanical mode, but there are many disadvantages, especially the loss of power and difficult maintenance.
Knowing that this kind of thing will enter thousands of households sooner or later, Ren Baqian naturally directly passed this kind of thing.
What he used was the more mature crossbar switch technology.
In the 1950s and 1960s on Earth, the use of such switches has become mainstream.
In China, it was used until the 1990s.
Of course, this is also a technology that will be eliminated sooner or later.
But what the next generation of technology needs is electronic technology.
Ren Baqian waited for a long time before the expressions on everyone's faces gradually began to show.
"Huh?"
"What does your Highness mean, that this thing can be installed in our house?"
"Not just your house, but everyone's house, even those villages on the mountain!"
Ren Baqian corrected.
Of course, there is a prerequisite for this, first drive away those beasts who have nothing to do with wires!
The cities are alright, but there are many ferocious beasts in the wild who like to pull wires or dig holes.
"Huh?"
Everyone suddenly exclaimed.
Everyone has such a phone in their home? —
