The Empress’s Gigolo

? After school that day, the students in this session are all indifferent, and their eyes are floating dull.

After suffering for six years, I thought I could finally see the light, but found that it was deeper darkness that greeted me.

Thinking about the next four years, everyone would cry.

Other students at the beginning wondered why these seniors had been elated lately, and suddenly they were not as good as dead.

When they knew the situation, they also changed face to face.

The future of these seniors is their future ...

Life is better than death, and naturally someone rejoices.

Zhan Caixian, for example, loves it here.

There are teachers, and the students are also interesting. They can learn all kinds of interesting things, and they can go to the library to watch interesting cartoons.

She doesn't like to work in any department, and she doesn't lack money at home. She has been studying in this school, and that's the best!

Ten days later, the first student graduated again, but this graduation party was much humbler.

And this time, among the civilian families, except for one person, all of them chose to graduate.

After all, for them and their family, it is enough to learn today. Learning for another four years is too stressful for them. After all, the family situation of ordinary people cannot support them to continue to learn like this.

They don't want to.

Nowadays, Da Yao is at a time of change. Lancheng and Da Yao are different each month. When they were studying at the school, they often had the idea of ​​participating.

So they chose to graduate and enter six posts.

In this regard, Ren Baqian also understands.

As for the powerful neutrons, none of them has graduated.

All went to college.

In a mourning, the first thing to meet them was the entrance exam one month later.

...

At this time, the eyes of a group of people were on a small table in the center.

On the table is a black box with a disc with numbers 0 to 9 written on it.

The box also has a cord that leads to the outside of the hall.

Ren Baqi held the microphone on the box with one hand and turned the disc with one hand. A short beep sounded after a while.

With one beep, the other end was picked up.

"His Royal Highness?"

"We succeeded!" Ren Baqian smiled as he watched the crowd.

The crowd did not respond, and the other end of the phone cheered.

Ren Baqian spoke a few words of relief to the other end of the phone, then hung up the phone, and looked at everyone in the hall with a smile.

"His Royal Highness, isn't this the same as the previous radio?" Shi Qing asked.

Although Ren Baqian did not explain, they had already guessed the purpose of this box.

"No, the radio is a radio station. The radio station is our conversation on each channel, which belongs to fixed-frequency communication. There are several disadvantages. First, the number of fixed frequencies is limited, and it is impossible for radio stations to be used by everyone.

Second, if others get a radio station, they can hear the conversation on the channel.

Although this has not happened before, it does not mean that it will not happen in the future.

Thirdly, the radio station is weak in anti-interference ability. For example, in the skyscape, the radio station cannot be used. "

Everyone did not understand technology, nor did they understand the meaning of any eight thousand words.

Just from Ren Baqian's words, this box is better than a radio station.

"You can introduce it." The empress sat down indifferently.

"Yes!" Ren Baqian gave the Empress a smile.

Turning around: "This is the phone, the same as the radio station for long-distance communication.

There is no need to say more, just 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 have a point-to-point call with any one of the six divisions or any department in any city at any time, and said everything can only be heard by the people at both ends of the phone. "

Everyone nodded, this time they understood.

The radio station is for everyone to chat together, and this phone is for two people to chat in private.

"Secondly, the most important thing is the popularity of telephones. Telephones can be deployed anywhere in Dayao, and there can be millions and tens of millions of telephones.

Whether it is each department, each city, or even every household.

Everyone can talk to one of these millions and millions of phones through a phone number.

For example, Lord Shi can install such a phone in his own house.

As long as I have the corresponding telephone number in the home of Mr. Shi, I can call Mr. Shizhong from any place at any time and call him.

For example, adults can be in any corner of Lancheng, or in any corner of Dayao, even in the 60,000 mountains, you can also contact the government by telephone. "

After Ren Baqian said something, he looked at everyone with a smile.

You have to wait for them to react for a while.

Although they have seen enough new things over the years, it still takes a little time to digest Renbaqian's words.

On the earth, the early application of the telephone was a magnet telephone, which was the type in the movie that made a call while generating electricity by hand, and then transferred by an operator.

After that, it was a common telephone, and no manual power generation was required, but the operator of the telephone office still needed to continue the connection manually.

This type of telephone requires manual transfer, so without a few digits, the number of natural users is unlikely to be large.

At the time, Asia's largest magic city telephone office had only a few thousand users.

The biggest restriction on telephones is not the technology of telephones, but the technology of telephone interaction.

Both of the above are manual connection, and then the step-by-step switch can already connect the phone through the mechanical mode, but there are many disadvantages, especially large loss and difficult maintenance.

Knowing that this kind of thing will enter millions of households sooner or later, Ren Baqian will directly pass it off.

What he uses is the more mature crossbar switch technology.

In the 1950s and 1960s, the use of such switches has become mainstream.

In China, it has been used until the 1980s and 1990s.

Of course, this is also a technology that will be eliminated sooner or later.

But the next generation of technology requires electronics.

Ren Baqian waited for a long time, and then the faces began to gradually move.

"what?"

"His Royal Highness ~ www.readwn.com ~ Is this thing fit in our house?"

"Not just in your house, but in everyone's home, even those cottages on the mountain!"

Ren Baqian corrected.

Of course, there is a premise. First, get rid of the birds and beasts who are okay with the wires!

The cities are okay, there are many beasts in the wild who like to pull a wire or dig holes.

"what--?"

The crowd suddenly exclaimed.

Everyone has such a phone in their home?
