yes!

After the hot air balloon is launched, the lowest attack height is also above 100 meters and below 150 meters.

This height is impossible to communicate directly through voice.

In the past, their communication methods were through carrier pigeons.

Although the carrier pigeon is very fast, it still takes a certain amount of time.

Furthermore, the transmission of information by carrier pigeons is sometimes not safe.

Because during the transmission process, the carrier pigeon is likely to be shot down.

But now with the walkie-talkie, it’s completely different!

Through the walkie-talkie, you can directly and live conversations.

Lu Sheng couldn't help but say to Lu Bu excitedly: "Father, let's see if this walkie-talkie is easy to use!"

Lu Bu nodded, and then Lu Sheng went out with the walkie-talkie excitedly.

Lu Sheng walked far away, about 200 meters away, then turned on the walkie-talkie, pressed the speech button, and said in a normal voice: "Father, I am Sheng'er, can you hear it?"

Soon, Lu Bu's voice came from the walkie-talkie: "Sheng'er, Sheng'er, the father can hear it, the voice is very clear!"

Lu Sheng continued to experiment and finally found that the effective distance between the walkie-talkie is 300 meters. If it exceeds 300 meters, the sound begins to be chaotic.

More than 350 meters, there is no signal directly.

However, the distance of 300 meters is barely enough at present.

Of course, it must be continuously improved.

After all, the distance between 300 meters is really too short on the battlefield.

The commander must follow the hot air balloon and keep running...

Next, the experiment phone number.

The distance between the phone must be unlimited, but it must be completed through a dedicated telephone line.

Lu Bu was very satisfied with the quality of the phone.

After having the phone number, Lu Bu will install the phone number in important cities in Dahua.

If you have any important things in the future, you can contact us by phone.

There is no need to pass messages slowly through the post road as before.

Next, the phonograph that started experimenting was the phonograph.

Lu Bu turned on the phonograph and pressed the recording button, and said, "The road is long and arduous, I will search up and down!"

After recording the sound, Lu Bu pressed the play button, and soon, a sound came from the phonograph: "The road is long and arduous, I will search up and down!"

The sound was a little distorted, but you could hear it all at once. This was Lu Bu's voice.

This scene shocked Lu Sheng directly.

He couldn't help but stammer, "This is so amazing, right? Father, what is this?"

Lu Bu couldn't help but smile and said, "Well, it's called a phonograph. You can save the sound. Just press the play button to replay the sound."

After hearing Lu Bu's explanation, Lu Sheng couldn't help but say with his eyes lit up: "Father, this is good, this is good!"

"Hey, hey, hey! Father, can you reward the phonograph and this pair of intercoms to your sons?"

Lu Bu glanced at Lu Sheng, and a meaningful expression appeared on his face.

This guy is so anxious to have a phonograph and walkie-talkie, he must want to please his wife.

This guy is just a wife-lovers!

Lu Sheng's personality is completely different from that of the eldest prince Lu Bin.

As his name suggests, Lu Bin is gentle and has a calm personality.

And Lu Sheng is active by nature and has a strong martial arts skills.

But this guy is fine every few days. He always likes to go to Zhang Fei's mansion to meet his young wife.

If this matter is left in the family of those literati, even if you are the prince, they will never be allowed to meet before marriage.

It’s not nice to spread this kind of thing.

Besides, if they can't control themselves and come up with ideas, will everyone still have the face?

But Zhang Fei is not a literati, he is just a military general, and he doesn't care about these things at all.

Therefore, every time Lu Sheng went to Changfu, Zhang Fei not only did not chase Lu Sheng out, but also served him with delicious food and drinks.

Zhang Fei likes this son-in-law very much. Treating Lu Sheng is no different from treating his own son.

But Lu Bin is different. Lu Bin and Guan Yu's daughter are engaged, but they never come to pay their respects except for holidays.

Generally speaking, the people like young children, and the royal family favors the eldest son.

Most people love their youngest son the most.

And in the royal family, the eldest son is most valued.

But for Lu Bu, his favorite is his second son Lu Sheng.

Because among these sons of Lu Bu, Lu Bu felt that Lu Sheng was the most similar to him.

Therefore, in the face of Lu Sheng's request, Lu Bu did not think much and agreed happily.

Seeing that his father really agreed to his request, Lu Sheng was so happy that he thanked him happily, he picked up a phonograph and a pair of walkie-talkies and left happily.

...

After Lu Sheng left, Huang Chengyan couldn't help but say to Lu Bu: "Master, the camera will be developed soon. However, this TV will probably be difficult to develop in a short while."

Is a TV set? It requires a lot of electronic components, and it is probably not easy to develop with current technology.

Lu Bu couldn't help but nod and said, "Since that's the case, let's put the TV on it first."

"Now, you're starting to develop rifles, cannons, mine demining vehicles and tanks."

Let me tell you, Lu Bu explained the current situation in Dahua and Cao Wei to Huang Chengyan in detail.

After listening, Huang Chengyan couldn't help but look thoughtful on his face.

At this stage, the most important research of Dahua is to be placed on cannons and mine-de-de-cart.

As long as you have these two new weapons, you can easily crush Cao Wei.

With mine demining vehicles, you will no longer be afraid of Cao Wei’s landmines.

With cannons, they can easily blast open their city gates.

As for rifles and tanks, it is still the second.

Because even without these two new weapons, as long as there are mine-de-detached vehicles and cannons, they can easily crush Cao Wei.

But if you want to conquer the whole world, you must use rifles and tanks.

After understanding the situation, Huang Chengyan took the research drawings from Lu Bu and hurriedly left.

...

After finishing the business, Lu Bu walked into the harem to find Queen Cai Yan.

After staying in Yuzhou for several months, Lu Bu missed Queen Cai Yan very much.

After arriving at Qianning Palace, I saw Empress Cai Yan leaning against the door and looking at her.

After seeing Lu Bu, he couldn't help but blessed and said, "I have seen the emperor!"

Lu Bu took a step forward, helped Cai Yan up, and looked at him intently.

Yan'er seemed to have lost weight again.

Lu Bu felt ache in his heart and couldn't help but hold Cai Yan tightly in his arms.

Cai Yan couldn't help but blushed, patted Lu Bu's chest gently, and said coquettishly: "Your Majesty, this is still at the door, why don't you let go? Let those palace maids and father-in-law look at it, what will it look like?"

Lu Bu smiled and said, "I hold my wife, I think anyone dares to gossip?"
