Lu Bu called Huang Chengyan and said to Huang Chengyan: "Best-in-law, don't work too hard on everything. Leave the matter to your subordinates. Just take control of the General Administration."

"If you do everything yourself, wouldn't you be exhausted? I also want the father-in-law to study more scientific research results for me and the people of Dahua!"

Huang Chengyan smiled and said, "Your Majesty, you don't know. I just like to do research. If you want me to be idle, I'm really not used to it! I'm afraid of being busy and tired. When I see the research results being developed, everything is satisfied!"

Then, Huang Chengyan seemed to have reacted something, and his eyes lit up and asked Lu Bu: "Your Majesty, do you mean, are you still trusting scientific research goals? What exactly is it? Take it out and show me?"

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

I know that this is how the father-in-law will manifest when he hears that there are new scientific research topics!

At this moment, Lu Bu couldn't help but say to Huang Chengyan: "Best-in-law, the next step I plan to let you study is telephone, telegraph, walkie-talkie, phonograph, camera, television, etc. to develop in these aspects."

With electricity, if there is no telephone or TV, wouldn’t it be wasted electricity?

With the TV set, we can better promote national policies in the future.

As the territory grows bigger, the timeliness of messaging will become crucial.

So, at this time, telegrams and phone calls become crucial.

As Lu Bu continues to expand outward in the future, he will not only need telegrams and telephones, but more advanced means of transportation will inevitably be put on the agenda.

Otherwise, you will conquer such a great country.

If there is a rebellion, your army will take several months or even half a year to pass. By then, the daylily will probably be cold.

Fast and efficient means of transportation are crucial.

The launch of the plane will be gradually put on the agenda.

In fact, Lu Bu hopes that Dahua can develop advanced transportation such as aircraft and other means of transportation.

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

You have to eat rice bite at a time, and you have to walk step by step.

What they are developing now is only the products they need most urgently and are currently the most urgent for them.

Other products can only be delayed backwards, and there is no way to do so.

After all, the time when Dahuaguo’s technology started was too short.

Despite the continuous expansion of the research institutes, the scale is still too small at present.

...

When Huang Chengyan heard about Lu Bu’s new scientific research goals, he immediately became interested.

He asked quickly: "What are the functions of the emperor, telegram, telephone, walkie-talkie, phonograph, camera, and TV?"

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

After hearing the emperor's words, Huang Chengyan couldn't help but look thoughtful on his face.

In fact, Huang Chengyan can really understand that he uses electricity to pass some digital passwords.

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

However, Huang Chengyan had never thought about using this phenomenon to convey messages before.

If it can be really achieved, then passing messages will break through the distance limit!

Although it is thousands of miles away, it can transmit information simultaneously.

This scientific research result is really amazing!

Lu Bu then explained: "The function of the telephone is similar to that of the telegram, but the function of the telephone is that two people can have a clear conversation, just as clearly as face-to-face conversation."

Hearing Lu Bu explaining to the phone, Huang Chengyan couldn't help but frown.

The phone number is a matter that Huang Chengyan can't understand.

Lu Bu did not explain more like him. It was difficult to explain the principles clearly in one sentence or two sentences.

At that time, just give him the structure diagram and principles and let him explore it slowly.

The walkie-talkie and phone behind are similar to each other, so Lu Bu did not explain much.

Next, Lu Bu has to explain it as a phonograph, camera and TV.

"As for phonographs, they use tapes or discs to save the sound, and then through the phonograph, the saved sound can be replayed at any time."

Um?

Hearing the phonograph as it was used, Huang Chengyan couldn't help but look confused on his face.

Is this really too abstract and too difficult to understand. Can the sound be preserved?

In the future, use a phonograph and listen whenever you want?

How can the sound be retained?

Huang Chengyan's head was about to explode.

Also, what is the purpose of retaining the sound?

I always feel that the phonograph the emperor mentioned today is not very reliable!

Then, Lu Bu explained the camera to Huang Chengyan.

"A camera is a special medium that has different sensitivity to light, and can clearly print transactions on the negative film. Then it comes out again, that is—"

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

Fortunately, Lu Bu remembers that he brought a camera to Hyundai to take birthday photos for his children.

Lu Bu immediately ordered his servants to send the camera from the palace.

After the camera came, Lu Bu couldn't help but say to Huang Chengyan: "Bestie, this is the camera. Don't move. Wait until I take a photo of the father-in-law, and then you will understand what the camera does."

Huang Chengyan looked at Lu Bu's strange cell phone, nodded in confusion, and then stood there in a proper manner.

Soon, Lu Bu adjusted the focal length and pressed the shutter with a click.

The shutter sounded and the flasher flashed, which scared Huang Chengyan.

Not long after, the photos were printed out directly.

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

Huang Chengyan took it and saw it, and was stunned by the shock. The boss with his mouth opened, and he could no longer close it.

Be good at thundering!

This, this is really 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 different sizes.

This feeling is so weird!

Is this the camera?

Is it so magical?

It took a long time to recover a little later.

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

It is indeed difficult to explain before you see the real thing.

This camera must be made as soon as possible!
Chapter completed!
