Lu Bu called Huang Chengyan and said to Huang Chengyan: "Guozhang, don't work too hard in everything, leave more things to your subordinates, you just need to control the General Bureau." ”

"If you do everything yourself, won't it exhaust you? I also want to make the national ruler for me and the people of Dahua to research more scientific research results! ”

Huang Chengyan smiled and said, "Your Majesty, you don't know, I like to do research." You're going to let me be idle, I'm really not used to it! When I see the research results being developed, everything is satisfied! ”

Then, as if he had reacted to something, Huang Chengyan's eyes couldn't help but light up, and he asked Lu Bu: "Your Majesty, what do you mean, do you have any scientific research goals for faith?" What is it? Hurry up and take it out and show it to the minister, right? ”

Seeing Huang Chengyan's impatient appearance, Lu Bu couldn't help but smile helplessly.

I knew that as soon as Guozhang heard that there was a new scientific research topic, it would behave like this!

At that moment, Lu Bu couldn't help but say to Huang Chengyan: "Guozhang, in the next step, I plan to let you study in the direction of telephone, telegraph, walkie-talkie, as well as gramophone, camera, television, and other aspects to develop." ”

With electricity, if there is no telephone or television, wouldn't it be a waste of electricity?

And with the TV, we will be able to better publicize the national policy in the future.

As the territory grows, the timeliness of messaging will become critical.

So, at this time, the telegraph and telephone became crucial.

In the future, as Lu Bu continued to expand outward, not only telegraphs and telephones were needed, but more advanced means of transportation were bound to be put on the agenda.

Otherwise, you'll be so big.

In case of a mutiny somewhere, it will take months or even half a year for your army to pass, and by then, it is estimated that the daylily will be cold.

Fast and efficient transportation is crucial.

The advent of airplanes will be gradually put on the agenda.

In fact, Lu Bu can't wait for Dahua to be able to develop airplanes and other advanced means of transportation now.

However, there are too many modern products that Dahua needs to develop now.

The meal should be eaten one bite at a time, and the road should be taken step by step.

What is being developed now can only be the products they urgently need and are most urgent for them at present.

Other products can only be postponed, which is also a matter of no choice.

After all, the time for Dahuaguo Technology to start is still too short.

Although the research institute has been expanded repeatedly, the scale is still too small for now.

……

Hearing about Lu Bu's new scientific research goals, Huang Chengyan immediately became deeply interested.

Hurriedly asked: "Your Majesty, what is the effect of telegraphs, telephones, walkie-talkies, as well as gramophones, cameras, and televisions?" ”

Lu Bu explained to Huang Chengyan: "The telegram means that although we are far apart, even thousands of miles away, I will send a set of digital passwords here, and you can receive them thousands of miles away, and then translate the digital passwords into Chinese characters." ”

After listening to the emperor's words, Huang Chengyan couldn't help but show a thoughtful look on his face.

In fact, Huang Chengyan can really understand the transmission of some digital passwords with electricity.

Because when he was studying power stations, Huang Chengyan had discovered this phenomenon.

However, using this phenomenon to deliver news, Huang Chengyan didn't think about it before.

If it can really be realized, then the transmission of messages will break through the limitation of distance!

Although it is thousands of miles away, it allows people to transmit information synchronously.

This scientific research achievement is really remarkable!

Lu Bu then explained: "The function of the telephone is similar to that of the telegraph, except that the function of the telephone is that two people can have a clear conversation from a distance of thousands of miles, just as clearly as a face-to-face conversation. ”

Hearing Lu Bu's explanation to the phone, Huang Chengyan couldn't help frowning.

The phone call is something that Huang Chengyan can't understand.

Lu Bu didn't explain as much as he did, and it was difficult to explain the principle in one sentence or two.

At that time, just give him the construction diagram and the principle directly, and let him explore it slowly.

The walkie-talkie and the phone in the back have similar functions, and Lu Bu also didn't explain much.

Next, Lu Bu has to explain the gramophone, the camera, and the television.

"As for the phonograph, it is to use the medium such as tape or disc to save the sound, and then through the phonograph, the saved sound can be replayed at any time."

Well?

Hearing the effect of the gramophone, Huang Chengyan's face couldn't help but show a blank look.

This is too abstract and incomprehensible, and the sound can still be preserved?

In the future, when you use a gramophone, you can listen to it whenever you want?

How can the sound be preserved?

Huang Chengyan's head was about to explode.

Also, what is the use of sound preservation?

I always feel that the gramophone that the emperor said today is not very reliable!

Then, Lu Bu explained the camera to Huang Chengyan.

"Cameras, in the case of a special medium, can clearly print transactions on the negatives with different sensitivity to light. And then come out again, and it's—"

Well, after introducing for a long time, Lu Bu felt a little headache, and he didn't know how to introduce the camera to Huang Chengyan for a while.

However, fortunately, Lu Bu remembered that he brought a camera in modern times, ready to take birthday photos for his children.

Lu Bu immediately ordered someone to send the camera from the palace.

After the camera came, Lu Bu couldn't help but say to Huang Chengyan: "Guozhang, this is the camera, don't move, wait for me to take a picture of Guozhang, and then you will understand what the camera is for." ”

Huang Chengyan looked at the strange-looking mobile phone in Lu Bu's hand, nodded suspiciously, and then stood in place in an orderly manner.

Soon, Lu Bu adjusted the focus and clicked the shutter.

As soon as the shutter sounded, the flash flashed, which startled Huang Chengyan.

It didn't take long for the photo to be printed out with a click.

Lu Bu took out the photo and showed it to Huang Chengyan.

Huang Chengyan took it and took a look, and was directly stunned, and the boss with his mouth open couldn't close it anymore.

Boom!

This, this, is truly amazing!

How can it be so similar?

The scene in front of me is exactly the same as the one in the photo, except for the difference in size.

This feeling is so weird!

This, is this what a camera is?

Is it so magical?

After a long time, Huang Chengyan recovered a little.

At this time, I finally understood why the emperor couldn't explain it.

It's really hard to explain until you see the real thing.

This camera must be made as soon as possible!
