Otaku Engineer in Great Tang Dynasty

"Heh~! Li Zexuan, what else do you have to say now? You are so brave to lie to me. Tell me what is ringing in this room?"

Li Er also heard the "dip" sound in the back room, and he instantly remembered what Zhao Song had reported to him when he was in the palace at noon, so he pretended to impose dignity on Li Zexuan. He wanted to go in and search directly, but as a dignified emperor, it was already very wrong for him to come to the outside room of Li Zexuan's bedroom. How could he go into another person's inner room?

Er, when Li Zexuan looked at Li Er's appearance, he didn't know whether Lao Li was really angry or falsely angry. After all, he was not Lao Li's opponent in terms of acting. He said with a guilty conscience:

"Your Majesty, the minister has not deceived you from beginning to end! This is just a little gadget that the minister made to please his fiancee. It's not worth mentioning and can't be on the stage!"

"Oh~? What exactly can please my daughter's house, Li Siye, take that thing out and show it to the palace!"

Empress Changsun laughed softly at this time.

Alas, Li Zexuan sighed. It seems that it won't work if you don't take it out. I can only hope that Li Er has a moral bottom line, and don't confiscate his tool for "dating in love"!

"Yes, mother!"

Li Zexuan arched his hands, honestly went in and carried out the pile of devices, and placed them on the table between Li Er and the eldest grandson.

"Your Majesty, Niang Niang, these are the little things that the little minister made up for his fiancee."

"What is this thing called? What's the use? Why is it so ugly?"

Looking at this strange and ugly machine, Chang Sun 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 appearance. Uh, he judged things by appearance. After looking at the machine with many threads, he said:

"Don't hide and tuck you kid, let's be honest! I and the queen won't **** your things, look at your stingy ghost, you are still the Imperial Supervisor in vain, and you will be ashamed of the court if you say it."

What a shrewd person he is. Naturally, he was aware of Li Zexuan's strong guard when he first came in. Thinking of this, he was a little bit angry for no reason. He is a dignified king of the country, would he still **** things from you?

Li Zexuan rolled his eyes secretly, and slandered your old man for stealing from me. The gods were drunk and robbed directly into the palace as royal wine.

"Your Majesty, this is called \'telegraph\'. It is a tool used by the minister to contact my fiancee. It has not been completely successful yet, and it is still in the testing stage."

"How can such a small box realize communication between two people?"

Li Er heard Li Zexuan's magic, but he didn't believe it.

Empress Changsun also cast a curious look.

"Um, Your Majesty, this telegraph is divided into two parts: a transmitter and a receiver. The transmitter can send a signal through this key, and it can be received by another telegraph dozens of miles away. When this signal is reached, people over there can translate the message sent by the sender according to the sound of \'DiDi\'!"

Li Zexuan was stunned when he was asked, not because he didn’t know how to explain, but because he didn’t know where to start to explain to Li Er and Changsun. They had no basis in electromagnetics. It would be too difficult to explain to them clearly. Up. After much deliberation, he simply introduced the principle briefly. If Li Er and the eldest grandson don't understand it, then forget it.

Of course Li Er didn't understand. He frowned. After Li Zexuan finished speaking, he looked unhappy and said, "Speaking of people!"

"Uh...!"

Li Zexuan was choked to death. He pondered for a moment and realized that there was no way to explain it in a few words. He could only say:

"Your Majesty, Niangniang, the principle of this telegraph machine involves a lot of knowledge of electromagnetics. The minister can't explain it in a short time, but your majesty and Niangniang just need to know that the minister sends out a "Didi Di" here. The sound of "di", another telegraph machine tens of miles away can also receive this same sound. This is how two people can communicate with each other."

"Dozens of miles? Can you spread so far?"

Li Er saw that Li Zexuan did not deliberately prevaricate. He understood that the principle of this telegraph machine was really not explained clearly in a few words. He skipped the parts that he didn't understand and grasped the most critical information in Li Zexuan’s words. Asked.

"It's true. The current telegraph machine that was originally made, after being tested by the minister, can reach at least eleven miles away, and this should not be the limit. In theory, if this telegraph machine is the ultimate, it can make this Two people in any corner of the earth can communicate with each other, and the transmission is almost completed in the blink of an eye!"

Now that the telegraph machine has been taken out, Li Zexuan doesn't intend to hide anything, and he can also install a wave in front of Li Er by the way, how happy! If his parents in his previous life knew that he had pretended to be in front of Tang Taizong, the emperor of the ages, they would definitely be very pleased.

"People anywhere can send messages to each other in the blink of an eye? Hiss~!"

Li Er carefully recalled the words Li Zexuan just said several times~www.ltnovel.com~ I couldn't help but have a toothache, which was really shocking! Compared with this era, people often use post stations, pigeons, and beacons to transmit messages. The telegraph transmission that Li Zexuan said has completely subverted everyone's cognition!

"There is something unclear in this palace. Can Li Xian male answer the questions in this palace?"

Empress Changsun always looks like water, she looked at Li Zexuan and asked with a smile.

"Niangniang, please speak! The minister will know everything!"

Compared to Li Er, a jackal, tiger and leopard in sheep's clothing, Li Zexuan preferred to talk to his eldest grandson. He felt that his eldest grandson was more gentle and virtuous, and had a better heart than Li Er. But before long, Li Zexuan would lament that he was blinded by thinking this way.

The grandson nodded and said: "According to what you just said, whether the message sent or received by this telegraph machine is the kind of "didididi" sound, but with this kind of sound, how can we know? What message does the other party want to deliver?"

Li Er also reacted, and he echoed: "The queen is right. How can the message be delivered based on the "Didi Didi" voice?"

Li Zexuan looked at the several eunuchs and maids who came with Li Er and the eldest grandson, hesitated for a moment, and solemnly said, "It's about confidentiality. Please keep your Majesty and Empress back!"

Li Er thought for a while and waved his hand: "You all step back for the time being, Zhao Song, you don't need anyone to come near when you are watching outside!"

It was rare for him to see Li Zexuan solemnly, and he realized the seriousness of the matter, so he retreated.

"promise!"

Zhao Song responded.

Brother Ji breathed a sigh of relief. He didn't want to listen to those secrets here. He followed the **** and the maid and slipped out.
