"Heh~! Li Zexuan, what else do you have to say now? What a bold man, he dares to deceive Yu me, tell me what is ringing in this room? ”

Li Er also heard the sound of "Didi" in the inner room, and he instantly remembered the situation reported to him by Zhao Song when he was in the palace at noon, so he pretended to be majestic and pressured Li Zexuan. He wanted to go in and search directly, but he was a dignified emperor, and it was already very inappropriate to come to the outer room of Li Zexuan's bedroom, how could he enter someone's inner room again?

Well, Li Zexuan looked at Li Er's appearance, and he didn't know if Lao Li was really angry or fake, in terms of acting skills, he was not Lao Li's opponent after all, he was a little weak-hearted:

"Your Majesty, the minister has never deceived you from beginning to end! This is just a gadget made by the minister in order to please his fiancée, it is not worth mentioning, and it cannot be put on the stage! ”

"Oh~? What is it that can please your daughter's family, Li Siye, you quickly take out that thing and show it to the palace! ”

At this time, Empress Changsun chuckled.

Alas, Li Zexuan sighed in his heart, it seems that it will not work if he doesn't take it out, he can only hope that Li Er has some moral bottom line, don't confiscate the tool he used to "fall in love"!

"Yes, sis!"

Li Zexuan arched his hand, honestly went in and took out the pile of devices, and put them on the table between Li Er and the eldest grandson.

"Your Majesty, Niangniang, this is the gadget that the minister made up for his fiancée."

"What's this thing called? What's the use? Why do you look so ugly? ”

The eldest grandson looked at this strange and ugly machine, frowning and puzzled. No matter how she thinks about it, she doesn't think this thing can please girls.

Li Er didn't judge people by their appearance, but by their appearance, he looked at the machine with many wires, and said:

"Don't hide it, you kid, tell me the truth! I and the queen won't rob you of your things, looking at your stingy ghost, you are still the supervisor of the country in vain, and you will be embarrassed by the court if you say it. ”

What a shrewd person he is, naturally from the time he first came in, he was aware of Li Zexuan's strong vigilance, thinking of this, he felt a little angry in his heart for no reason, I am the king of a country, will I still rob you of things?

Li Zexuan secretly rolled his eyes, and slandered in his heart that your old man robbed me of something less? The immortals were drunk and were directly robbed to the palace as imperial wine.

"Your Majesty, this is called the 'telegraph', which is a tool used by the minister to communicate with my fiancée, and it has not yet been completely successful, and it is still in the testing stage."

"With such a small box, how can the two of them be connected?"

Li Er listened to what Li Zexuan said, but he was a little unconvinced.

Empress Eldest Sun also cast a curious gaze.

"Well, Your Majesty, this telegraph is divided into two parts: the transmitter and the receiver, the transmitter can transmit a signal through this key, and another telegraph machine dozens of miles away can receive this signal, and the people over there can translate the message sent by the sender according to the 'Didi' sound!"

Li Zexuan was stunned when asked, not that he didn't know how to explain, but that he didn't know where to start explaining to Li Er and Changsun, the two of them didn't have a little foundation in electromagnetism, and it would be too difficult to completely explain it to them. After thinking about it, he simply simply introduced the principle, and if Li Er and the eldest grandson didn't understand, forget it.

Of course Li Er didn't understand, he frowned when he heard it, and after Li Zexuan finished speaking, he looked unhappy and said, "Talking about people!" ”

"Uh...!"

Li Zexuan was choked half to death, he pondered for a moment, and found that there was no way to explain it in a few words, so he could only say:

"Your Majesty, Niangniang, the principle of this telegraph involves a lot of knowledge of electromagnetism, and Xiaochen really can't explain it in a short time, but His Majesty and Niangniang only need to know that Xiaochen makes a "Didi Didi" sound here, and another telegraph machine dozens of miles away can also receive this same sound, and this thing is how two people can communicate with each other. ”

"Dozens of miles? How can it be transmitted so far? ”

Li Er saw that Li Zexuan was not deliberately prevaricating, and understood that the principle of this telegraph machine could not be explained clearly in a few words, so he directly skipped the parts that he didn't understand, grabbed the most critical information in Li Zexuan's words, and asked.

"That's true, the current initial telegraph, after the test of the minister, has been able to transmit at least eleven miles away, and this should not be the limit, theoretically speaking, if this telegraph is done to the extreme, it can allow two people in any corner of the land to transmit messages to each other, and the transmission is almost completed in the blink of an eye!"

Now that the telegraph has been taken out, Li Zexuan doesn't plan to hide anything, and he can also pretend to be a wave in front of Li Er's eyes by the way, wouldn't it be happy! If his father and mother in his previous life knew that he had pretended to be in front of Tang Taizong, the first emperor of the ages, they would definitely be very pleased.

"Can people anywhere send messages to each other in the blink of an eye? Hiss~! ”

Li Er carefully recalled what Li Zexuan had just said a few times, and couldn't help but have a toothache, it was really shocking! Compared with the ways that people often use in this era, such as post stations, carrier pigeons, and beacon fires, the kind of telegraph transmission that Li Zexuan said has completely subverted everyone's cognition!

"There is something unclear in this palace, can Li Xiannan solve the confusion of this palace?"

Empress Eldest Sun always looked like she was as plain as water, she looked at Li Zexuan at this time and asked with a smile.

"Mother, please speak! The minister must know everything! ”

Compared with Li Er, a jackal tiger and leopard in sheep's clothing, Li Zexuan prefers to talk to the eldest grandson, he feels that the eldest grandson is more gentle and virtuous, and his heart is better than Li Er. But it won't be long before Li Zexuan will sigh that he is blind when he thinks so.

The eldest grandson nodded and said, "According to what you just said, whether this telegraph sends or receives, it is the kind of "didi-di-di-di" sound, but with this kind of voice, how can you know what message the other party wants to deliver?" ”

Li Er also reacted, and he echoed: "The queen is right, how can the news be delivered just with this "Didi Didi" voice? ”

Li Zexuan looked at the several eunuchs and palace maids who came in with Li Er and the eldest grandson, hesitated for a moment, and said solemnly: "It's a matter of confidentiality, please ask Your Majesty and Niangniang to step back!" ”

Li Er thought for a while, waved his hand, and said, "You all stand aside for the time being, Zhao Song, you watch outside, you don't need anyone to get close!" ”

He saw that Li Zexuan was rarely solemn, and he also realized the seriousness of the matter, so he withdrew from his subordinates according to his words.

"No!"

Zhao Song responded.

Brother Ji breathed a sigh of relief, he didn't want to listen to those secrets here, he slipped out with the eunuch and palace maid.
