"How do you know it's a good thing?" Gu Baozhu looked at him funny, feeling that he was still a fortune boy.

The old leader beckoned her to sit down, and then said, "It's a good thing for you to see me when you see me, even if there is no good thing, if you come, it's a good thing." ”

"Old leader, you really guessed it, it's really a great thing."

Gu Baozhu didn't sell it, took out the two mobile phones in the bag, and then took out the signal base station.

"What is this?" The old leader was confused.

"That's good stuff." Gu Baozhu smiled mysteriously and handed over the mobile phone in his hand.

"Old leader, this is a mobile phone, and it is also called a mobile phone abroad."

"Mobile phone?" The old leader frowned.

He knew that country M had a mobile phone that could communicate wirelessly.

But the phone was very large, brick-sized, and slightly bulky.

The mobile phone in Comrade Xiao Gu's hand is only the size of a palm, is this really the same?

"Yes, it's a mobile phone, I prefer to call it a mobile phone." Gu Baozhu grinned, not unhappy at the old leader's puzzled gaze, and continued.

"What I'm saying might be hard to believe, just wait, I'll show you it and you'll know."

Gu Baozhu's mobile phone functions may not be very much compared to those of later generations, but for people of this era, it is definitely a shocking existence.

After Gu Baozhu's simple display, the old leader was directly stunned.

"This, this?"

With such a palm-sized thing, you can take pictures and listen to music!!

It's incredible, how is this all done?

Not only that, but there are more explosives to follow.

Gu Baozhu dialed a string of numbers on one mobile phone, and the other mobile phone rang, which was still a red revolutionary song.

"Old leader, you press here, this is the answer button!"

The old leader trembled and pressed the answer button, Gu Baozhu grinned, "Old leader, you put this in your ears, and I'll go outside." ”

Gu Baozhu walked out as he spoke, and only when he walked into the courtyard did Gu Baozhu start to speak.

"Old leader, can you hear me?"

"Yes!" The old leader on the other end of the phone was very excited.

Gu Baozhu said a few more words, and then returned to the study with his mobile phone.

At this time, the old leader was already excited, he looked at the mobile phone in his hand, and his face was red with excitement.

Technology changes life, it's all real.

"Comrade Xiao Gu, this, this can really talk."

Gu Baozhu looked proud, "Of course, I just said that this is a mobile phone, which can also be called a wireless phone, let me tell you, a mobile phone is equivalent to an electromagnetic wave transmitter and an electromagnetic wave receiver."

The mobile phone transmits electromagnetic signals, receives them from a nearby receiving tower, and then sends the signal to the satellite, which sends the signal to the receiving tower, and then sends it from the receiving tower to the called mobile phone.

Sometimes mobile phones have no signal because electromagnetic waves are absorbed or scattered by airborne dust and water molecules in the air, causing the signal to weaken or disappear. ”

"Satellites?" The old leader asked uncertainly.

Gu Baozhu nodded, "Yes, it's the satellite." ”

"Our country has its own artificial satellite, because there is no signal base station set up, the signal receiving device of my two mobile phones has been improved, so it can use telephone signals to connect.

However, this is not a long-term solution after all, and the function driven by the telephone signal is also limited, so it is still necessary to set up a signal base station and use artificial satellites to transmit, so as to transmit information faster and more stably. ”

"You see, this is the small signal base station I made, with this base station, you can make calls at will within a radius of ten kilometers, I have the design drawings of the signal base station here, and there are some cost calculations for setting up the base station."

"The base station is large enough to cover a wide range, so there is no need to set up too many base stations."

She has made a lot of technical improvements to the signal base station, and she uses the technology from the interstellar side, which is naturally different.

"Good, good, good!"

The old leader happily slapped the table.

He immediately thought of the various uses of mobile phones, especially this kind of small and portable mobile phone, which has a wider range of uses, which is not a big brick like abroad.

"Comrade Xiao Gu, you have to surprise me every time we meet, you, you are really ......"

The old leader is already incoherent with joy, God bless Huaxia.

"Don't be too busy getting excited, I have a surprise here."

Gu Baozhu took the computer out of his backpack and looked at him with a smile, "Guess what this is?" ”

Seeing that the old leader was confused, Gu Baozhu didn't sell it, and told him directly, "This is a computer." ”

"I didn't ask you for a bulky desktop computer before, but after more than a month of disassembly, I built a portable computer myself, you see, isn't it very convenient."

Old leader: This is a computer?

Gu Baozhu couldn't care about the old leader's shock, she directly turned on the computer and continued to demonstrate the functions of the computer to the old leader.

Although the old leader is not a scientist, he can also peek into some of the future, and Gu Baozhu's hand is directly Wang Zhan.

"Old leader, after the construction of the signal base station, the computer can also be networked with microcomputers, and the computer can not only be used for huge computing, but also has many uses."

"As you just saw, I have written a lot of programs and software on it, and there are many basic functions on it that can be used without the Internet, I ......"

"Comrade Xiao Gu, I don't understand what you say, do you mind if I call a few experts in information technology to come over and listen to it together?"

"Don't mind." Gu Baozhu smiled and shook his head.

These techniques were meant to be handed over, and of course she didn't mind letting someone who knew how to come over and communicate.

The old leader was very fast, and immediately asked Secretary Zhang to invite all the bigwigs in this area.

While waiting for the experts to come over, Gu Baozhu taught the old leader to play the game hand in hand.

These small games are very simple, but they are also some puzzle games, especially chess games, and the old leaders play them quite energetically.

After playing the game for a while, the old and the young started to exchange ideas about the future development trend.

Gu Baozhu also said his outlook on the outside world, after the two communicated, the old leader had a better outlook for the future, and there must be a place for them in the Xia Kingdom in the future.

Two hours later, two experts in information technology arrived.

"Chief."

"Professor Fang, Professor Ma, come quickly."

The old leader couldn't wait for them to see the mobile phone and computer provided by Comrade Xiao Gu, and he believed that the two professors must be shocked.

The two professors were really shocked, they rushed over non-stop when they got the news, and even put down the test in their hands, and naturally looked forward to the technology in Secretary Zhang's mouth.

"Comrade Xiao Gu, please introduce the two professors." The old leader looked at the past, and he still had to find a professional person to introduce professional things, so he would not command indiscriminately.
