The July sun is still very poisonous, so the demonstration of the use of radio transmitters is naturally not carried out in the square.

Emperor Hongzhi placed the location of the demonstration on the tower of the Forbidden City.

"Your Highness, this iron box is a radio transmitter? No danger, right? ”

Xiao Jing still has doubts about Zhu Houzhao, if there is any problem with this radio transmitter, such as an explosion or something, then the Ming Dynasty will be in chaos in the world, the emperor, the old heavenly group of the three pavilions, the ministers who rushed to hear the news, and the Hanlin who came with them, are all here.

It can even be said that the civil officials above the fifth grade in the capital have basically arrived.

If this is a bomb, it will really be all over.

"Dog thing, this palace has endured you for a long time, and you are still suspicious of this palace, are you looking for a fight?"

Zhu Houzhao clenched his fists, this time he didn't bother with Xiao Jing, but urged Xiao Jing:

"Hurry up and arrange someone to send another radio transmitter and Liu Wu, who is using a radio transmitter, to a distant place."

Zhu Houzhao's urging did not make Xiao Jing act immediately, he looked at Emperor Hongzhi and waited for Emperor Hongzhi's opinion.

Emperor Hongzhi nodded at him, and Xiao Jing went to arrange for people to act.

……

"Father, you see, this is a keyboard, marked on the keyboard, it is the Chinese pinyin alphabet made by Li Zhaotong, so if you want to learn how to use this radio transmitter, you must first learn Chinese pinyin."

The system is produced, and naturally it will not be stolen from any time and space.

The two radio transmitters that Li Zhaotong bought in exchange for 20 years are full of science and technology, and even in the 21st century, which is a few hundred years old, they will not be outdated.

Because it's a thing with a keyboard that looks a lot like a typewriter.

This radio transmitter, the use of Morse code is not used, but pinyin input method, its working mode, is the use of the radio transmitter here to send the person, which button pressed, the key will emit the corresponding key electromagnetic waves, so that another telegraph machine emits the sound of the corresponding button.

The person who receives the telegram records the corresponding keys according to the different sounds, and then spells them out in pinyin.

The process is very complicated, because the pronunciation or something needs to be corresponded to one by one, so to use this radio transmitter, you need to be very familiar with the content on the manual.

This is also the reason why Li Zhaotong almost didn't look at it much, so he left it to Liu Wu and others to familiarize themselves with how to use it.

Because he felt that the system was completely cheating him, it was simple, how good it would be to build the most primitive radio station, and he had to build such a complex radio transmitter.

This purpose is clearly not to let him arrange someone to disassemble the cracking technology, so that he can learn to make a radio station.

Zhu Houzhao is indeed smart, in a short period of time, he can be said to be the second most proficient in the use of this radio transmitter in the whole world, as for the first, it is Wang Shouren, but Wang Shouren did not come back, so this time, it was Zhu Houzhao who personally sent the report.

Xiao Jing sent someone to let Liu Wu take the radio transmitter and did not go too far, just above the Zhengyangmen City Tower.

Soon, someone from Dongchang came back to report that Zhengyangmen was ready.

"Father, tell me what to say, lest these people say that I colluded with that side to deceive people."

The hundred officials standing on the city tower now, except for a few people in Li Dongyang, are full of suspicion about the radio transmitter.

After all, not everyone knows that Li Zhaotong can "get things from the sage Lao Tzu", so they don't believe in something that can only appear in myths like thousands of miles of sound.

"I'll decide?"

Emperor Hongzhi was a little surprised, because Zhu Houzhao had never been so polite to him, but Emperor Hongzhi did not hesitate, he thought about it and said directly:

"Just spread the word Daming to the other side!"

"Yes, Father."

—————

When Zhu Houzhao heard this, he immediately walked to the side of the radio transmitter and prepared to start the operation.

This radio transmitter naturally needs to use electricity, and this electricity is not conjured out of thin air, but requires someone to constantly hand crank a power generation device on the radio transmitter in order for the radio transmitter to work.

Beside Zhu Houzhao, there was a communication soldier from the Ming Imperial Guard, who helped Zhu Houzhao to hand the handle on the radio transmitter to generate electricity.

When the signal soldier shook the handle a few times, the radio transmitter was energized, and some indicators on it began to light up.

At this moment, it shocked all the audience.

Several of the more superstitious and timid people were frightened by the light of the indicator and retreated, fearing that the radio transmitter would explode.

The same goes for Xiao Jing.

He was not afraid of death, but was worried about the safety of Emperor Hongzhi, so he immediately protected Emperor Hongzhi and stood in front of Emperor Hongzhi.

"What's a fuss, isn't it just a light, this palace has already said that this palace will not harm its father, and if this radio transmitter is really as you think, if you want to blow it up, you will blow up the palace itself!"

Zhu Houzhao hadn't moved yet, so when he saw Xiao Jing frightened like this, he immediately sneered.

"Xiao Jing, get out of the way, I believe in the prince."

Emperor Hongzhi was quite calm, and when he saw Zhu Houzhao say this, he was even calmer, so he hurriedly asked Xiao Jing to stand aside.

Hearing Emperor Hongzhi's order, Xiao Jing naturally had no choice but to stand aside honestly.

Seeing that Xiao Jing no longer blocked Emperor Hongzhi's sight, Zhu Houzhao began to tap on the keyboard and pass on the sentence that Emperor Hongzhi had just said: Just pass on the words of the Ming Dynasty to another radio transmitter.

Soon, Zhu Houzhao's operation was as fierce as a tiger, and the information was transmitted.

On the other side, Liu Wu, who had already prepared, quickly wrote down the content sent by Zhu Houzhao and then deciphered it.

It didn't take long for Emperor Hongzhi's words to be deciphered by him.

"My lord, please hand this note back and see if the contents are correct."

"Okay."

The Dongchang fan didn't dare to slack off, knowing that the emperor, the crown prince and many officials were waiting on the upper floor of the Forbidden City, so he put away the note handed to him by Liu Wu, ran down the Zhengyangmen Tower, rode a fast horse, and ran towards the Forbidden City Tower.

……

The Forbidden City Tower.

"Father, look, you're here."

Zhu Houzhao was looking forward to his performance this time, so he was always staring at the bottom of the city tower, anxiously waiting for the news from Zhengyangmen.

At this moment, when he saw a fast horse, his eyesight was good, and he could see at a glance that it was someone sent out by Xiao Jing, and immediately, he happily called Emperor Hongzhi to come and see it.

When Emperor Hongzhi saw a fast horse coming, he also nodded slightly, looking forward to the result this time.

It's just that he didn't know that Zhu Houzhao passed all his words, and he didn't know how wonderful his face would be if he knew the result.
