Qiquge Workshop.
"Ha~! Li Zexuan, what else do you have to say now? You are so brave, you dare to deceive me. Please tell me what is making the noise in this room?"
Li Er also heard the beeping sound in the back room. He instantly remembered what Zhao Song had reported to him at the palace at noon, so he pretended to be majestic and put pressure on Li Zexuan. He wanted to go in and search directly, but it was already inappropriate for him, a majestic emperor, to enter the outer room of Li Zexuan's bedroom. How could he enter the inner room again?
"Well…"
Looking at Li Er's look, Li Zexuan didn't know whether Lao Li was really angry or fake. After all, he was not Lao Li's opponent in terms of acting skills. He felt a little guilty and said:
"Your Majesty, I have never deceived you from the beginning to the end! This is just a gadget that I made to please my fiancée. It is not worth mentioning and cannot be put on the stage!"
"Oh~? What exactly can please my daughter's family? Can Li Siye take out that thing and show it to me?"
At this time, Empress Changsun chuckled.
Alas, Li Zexuan sighed inwardly. It seemed that it was impossible not to take it out. He could only hope that Li Er had some moral bottom line and would not confiscate the tool he used to "fall in love"!
"Yes, concubine!"
Li Zexuan cupped his hands, went in honestly, took out the pile of items, and placed them on the table between Li Er and Changsun.
"Your Majesty, my empress, this is the gadget that I concocted for my fiancée."
"What is this thing called? What is it used for? Why does it look so ugly?"
Changsun looked at this strange and ugly machine and frowned in confusion. No matter how she looked at it, she didn't think this thing could please girls.
Li Er didn't judge people by their appearance. Well, he judged things by their appearance. After looking at the machine with many wires wound around it, he said:
"You kid, don't hide it, just tell me the truth! The Queen and I will not steal your things. Judging from your stingy appearance, it is useless for you to still be the director of the Imperial College. If you tell me, it will embarrass the court."
What a shrewd person he is. He noticed Li Zexuan's strong wariness when he first entered this room. Thinking of this, he felt a little angry for no reason. How could I, the king of this country, still steal things from you?
Li Zexuan rolled his eyes secretly and cursed in his heart. Didn't you steal enough things from me? The gods were drunk and taken directly to the palace to serve as royal wine.
"Your Majesty, this is called a 'telegraph'. It is a tool that I use to communicate with my fiancée. It has not been fully implemented yet and is still in the testing stage."
"How can two people communicate with each other in such a small box?"
Li Er heard what Li Zexuan said was magical, but he didn't believe it.
Empress Changsun also cast a curious look.
"Well, Your Majesty, this telegraph machine is divided into two parts: a transmitter and a receiver. The transmitter can transmit a signal through this key, and another telegraph machine dozens of miles away can receive it. After receiving this signal, people over there can translate the message sent by the sender based on the 'didi' sound!"
Li Zexuan was stunned by the question. It wasn't that he didn't know how to explain it, but that he didn't know where to start explaining it to Li Er and Zhang Sun. The two of them didn't have any foundation in electromagnetism. It would be really difficult to explain it to them completely. . After much deliberation, he simply introduced the principles briefly. If Li Er and Changsun didn't understand, forget it.
Of course Li Er didn't understand. He frowned when he heard it. After Li Zexuan finished speaking, he looked unhappy and said: "Speak in human terms!"
"Well...!"
Li Zexuan was choked to death. He thought about it for a moment and found that he couldn't explain it clearly in just a few words. He could only say:
"Your Majesty, Your Majesty, the principle of this telegraph machine involves a lot of electromagnetic knowledge. I really can't explain it clearly in a short time. However, Your Majesty and Your Majesty only need to know that I am sending out a "Didi di di" "Beep" sound, it is enough that another telegraph machine dozens of miles away can receive the same sound. This is how two people can communicate with each other."
"Tens of miles? How can it be transmitted so far?"
Seeing that Li Zexuan was not deliberately prevaricating, Li Er understood that the principle of the telegraph machine could not be explained clearly in a few words. He directly skipped the parts that he did not understand, captured the most critical information in Li Zexuan's words, and asked road.
"Indeed, this initial telegraph machine has been tested by Xiaochen and can already transmit at least eleven miles, and this should not be the limit. Theoretically speaking, if this telegraph machine achieves its ultimate goal, it can transmit this message to a distance of at least eleven miles. Two people in any corner of the world can communicate with each other, and the communication process can be completed almost in the blink of an eye!"
Now that the telegraph machine has been taken out, Li Zexuan no longer intends to hide anything, and he can also pretend to be a bitch in front of Li Er's eyes. Wouldn't it be nice! His parents in his previous life would definitely be very happy if they knew that he had pretended to be a show-off in front of Emperor Taizong of the Eternal Dynasty.
"Can people anywhere send messages to each other in the blink of an eye? Hiss~!"
Li Er carefully thought over what Li Zexuan had just said several times, and couldn't help but feel a bit of toothache. It was so shocking! Compared with people in this era who often use post stations, carrier pigeons, beacons and other communication methods, the telegraph communication Li Zexuan mentioned has completely subverted everyone's understanding!
"I have something unclear. Can Mr. Li County help me clear up my confusion?"
Empress Changsun always looked as plain as water. She looked at Li Zexuan and asked with a smile.
"Your Majesty, please speak! I must tell you everything I know!"
Compared to Li Er, a jackal and tiger in sheep's clothing, Li Zexuan preferred talking to his eldest grandson. He felt that his eldest grandson was gentler, virtuous, and kinder than Li Er. But it is estimated that it won't be long before Li Zexuan will understand how stupid his current thinking is.
Changsun nodded and said: "According to what you just said, this telegraph machine always makes that kind of "didi-dip-dip-dip" sound whether it is sending messages or receiving messages. But how can we know just with this sound? What message does the other party want to convey?”
Li Er also reacted, and he echoed: "The queen is right, how can the message be conveyed with just the sound of "didi, didi, didi"?"
Li Zexuan looked at the eunuchs and maids who came in with Li Er and Changsun, hesitated for a moment, and said solemnly: "This matter is confidential, so your majesty and empress, please step aside!"
Li Er thought for a while, waved his hand and said: "You all step aside for now, Zhao Song, you watch from outside, no one is allowed to come near!"
Seeing that Li Zexuan was rarely serious and realizing the seriousness of the matter, he followed his words and withdrew his men.
"promise!"
Zhao Song responded.
Brother Ji breathed a sigh of relief. He didn't want to hear those secrets here. He slipped out with the eunuch and the maid.
