When Li An arrived at the main gate of Daming Palace, two telegraph machines and dozens of subordinates were waiting there, waiting for Li An to make his debut.

Because these two transmitters are too big and luxurious enough, they immediately attracted the masses and businessmen passing by on the street, and many people unconsciously stopped, stood not far away and watched carefully, talking from ear to ear, and there were also bold people who would run over to ask about the situation, and then retreat and tell the masses who did not know the situation of the news.

The telegraph machine is not a secret, and it is to be made public sooner or later, so the technician in charge of the transportation did not hide it, told the surrounding onlookers about the incident, and told the masses to hurry up and not block the road.

But the masses who know the truth, how can it be so easy to leave, they can finally see such a rare thing, if they don't take a few more looks, how can they be worthy of themselves, so they don't leave, the crowd is gathering more and more, and the technicians in charge of guarding the machine are helpless.

"Li Shilang is here, Li Shilang is here, get out of the way, get out of the way."

Seeing that Li An finally came, most of the technicians came up and greeted Li An.

"Why are so many people gathered, the streets are going to be blocked, hurry up, move the machine into the palace, hurry up."

Li An opened his mouth and gave the order.

Because there are too many people gathered at the gate of Daming Palace, if you don't quickly lift the machine in, there will be more people gathered at the door, and it will be bad to block the road.

The technicians came early, so the ministers of the previous dynasty also saw this machine, and driven by curiosity, they all stopped to ask, and after getting a satisfactory answer, they stayed for a while and left, they did not dare to delay the business.

"There's nothing to see, it's all gone, gone."

After Li An and the machine all entered the palace, the guards in charge of guarding the palace gate began to drive away the people at the palace gate and told them to leave quickly.

"Li Shilang, where are these two machines going to be shipped?"

A technician asked.

Li An thought for a moment and replied, "One is placed in the Hongwen Pavilion, and the other is directly brought to the Zichen Palace, let's go!" Remember, the action must be fast, connect the line well, perform in front of His Majesty, and never make a mistake. ”

"Yes, Li Shilang, my subordinates understand."

The subordinate answered.

The machine only needs to be placed in the designated position, and there is no need to spend energy to assemble, the only thing that needs to be done is to connect the two machines with wires.

From Hongwen Hall to Zichen Palace, although it is not very far, but in fact it is not close, it is estimated that there are hundreds of thousands of steps, and such a distance, although it can not well reflect the value of the telegraph, but the purpose of the experiment is to verify the technology, not to be used in two places in the Daming Palace, otherwise it is really meaningless, in Li An's view, there must be at least fifty miles away, the telegraph has the meaning of existence, and the distance that can be reached quickly by horseback will become a decoration.

Therefore, after verifying the technology of the telegraph, the later use must be based on the city, such as connecting a wire between Chang'an and Luoyang, so that the news of Chang'an City can be transmitted to Luoyang City at a very fast speed, and this is faster than taking a train, which is of great significance.

Li An and the ministers came a little early, and when Li An entered the Zichen Palace, the emperor had not yet come, but all the ministers had arrived, and the emperor was left alone.

Because he was curious about the telegraph, when Li An entered the Zichen Hall with the machine, the ministers all gathered around, and their curious eyes were like children.

"Li Shilang, this thing is a machine that can transmit messages thousands of miles away?

Chen Xilie walked over, and the chrysanthemums on his face bloomed.

Li An didn't answer, just nodded quite satisfied, and this was enough.

"Oops! That's a good thing! Good stuff! How do you spread the news? Can you demonstrate this? ”

"Yes! Oh, yes! Let's also see the knowledge first. ”

"Li Shilang, what are you waiting for? Let's demonstrate! ”

The ministers were all interested, eager to see for themselves how the transmitter sent information.

Li An smiled, waved his hand and said, "Don't worry, don't worry, Your Majesty has not arrived, when Your Majesty arrives, it will not be too late to demonstrate." ”

"Then you can always reveal a little bit first! How can this box carry the news thousands of miles away?

Chen Xilie took the lead and asked again.

Yang Guozhong looked at the wires extending from the transmitter, and guessed: "There is a wire here, compared to the transmitter transmitting news through the wire!" It's incredible that a single thread can send news thousands of miles away. ”

The rest of the ministers also discovered that there was indeed a line connected to the outside, but it was not clear where it led.

"It's not that I don't want to say it, it's just that the principle of the transmitter is too complicated, and I can't explain it clearly for a while, and when His Majesty comes, I have to say it again, I really can't stand two sins."

Li An shook his head slightly, and didn't want to say anything more.

Li An carried a big machine to the Zichen Palace, and such an important news naturally quickly reached the emperor's ears.

Li Longji, who originally planned to linger for a while, heard that Li An had completed the machine, and hurriedly got up happily, Li An didn't want to eat breakfast, but only ate a few bites at the strong request of the concubine, and then couldn't wait to walk towards the Zichen Palace.

"San Lang, the concubine also wants to go and see."

As soon as the emperor walked not far, the concubine chased after him, and driven by curiosity, Yang Yuhuan also wanted to see what the transmitter looked like.

"Zichen Hall is a place to discuss government affairs, it's not appropriate for Concubine Ai to go, so it's better not to go!"

Li Longji opened his mouth and said.

"San Lang, I'll just take a look from afar, it's not okay if the concubine doesn't enter the hall, it's okay to be in the wall."

Yang Yuhuan asked again.

"How can I bear to let my concubine stand in the wall?"

The emperor looked a little embarrassed.

"It's okay, I just want to see it."

Yang Yuhuan continued to insist.

"Alright! Since the concubine is so insistent, then the concubine has been wronged. ”

Li Longji had no choice but to agree.

"Zhong Aiqing doesn't have to be polite, don't be aware."

As soon as the emperor arrived, he saw that the ministers were about to salute, so he waved his hand casually and exempted the ministers from saluting, because he was eager to see the machine invented by Li An, and he could already turn a blind eye to these salutes.

"Your Majesty, Weichen has finally lived up to expectations and developed the telegraph, please take a look at it."

Li An said.

Li Longji took a few steps forward, looked at the huge telegraph, and said, "Li Aiqing, this big guy is a telegraph, can transmit news thousands of miles away?" ”

"Yes, Your Majesty, exactly?"

Li An said affirmatively.

Li Longji was overjoyed when he heard this, and said, "Then how to deliver the news?" Why don't Li Aiqing demonstrate. ”

"Your Majesty, the telegraph machine needs to have a transmitter and a receiver to transmit news, it is the transmission between two telegraphs, here is just one of them, the other is exactly the same telegraph in the Chongwen Pavilion, between the two telegraphs, there is a wire connected, the news is transmitted from this wire, Your Majesty has any instructions to transmit to Hongwenkan."

Li An said.

When Li Longji heard this, he thought for a moment and said, "Let Hongwen Pavilion immediately take a copy of Taixue Zichen Palace." ”

"Yes, Your Majesty."

Li An responded, and personally picked up the brush, and wrote, 'Your Majesty's will, Hongwen Hall immediately sent the book of Taixue to Zichen Palace. ’

Once written, they were given to the technician in charge of the telegram and asked to send the emperor's decree immediately.

After the technician saw it, he immediately began to send it tick-tock, and Li Longji and the ministers were dumbfounded.

According to the film and television dramas of later generations, the people who send telegrams are all sitting, but in the palace, the emperor and the ministers are still standing, how can the little people who send the telegram sit down, so Ang Lee is very interested in letting the technicians stand and send telegrams, anyway, sending telegrams has nothing to do with standing and sitting, and it is not constantly sending, and it is not tiring to go anywhere after standing for a while.

"Just tick and tick like this, and the Hongwen Pavilion will receive my will?"

Li Longji looked puzzled, and felt that it was too incredible.

The ministers above the hall also all had incredible expressions, they really couldn't figure it out, how could they pass the news elsewhere by casually pressing the electric button, this was really amazing, far beyond their cognition.

Li An nodded with a smile and said, "Your Majesty, don't worry, the people in the room haven't moved, and when the people from the Hongwen Pavilion send the book of Taixue over, it won't be able to prove it." ”

At this time, it is not time to explain, and Li An does not want to explain the principle, only if the emperor and the ministers can really see the results, and then explain the principle, the effect will be better.

"Okay, I have time, I'll just wait."

Li Longji walked to his dragon chair, ready to sit and wait, after all, he was also relatively old, and it would be very tiring to stand all the time.

"Li Shilang, Hongwenguan has replied."

The technician quickly received an echo, and after a few moments of proofreading, he wrote a few words on a blank piece of paper and handed it to Ang Lee.

Li Longji hadn't walked to the dragon chair yet, and when he heard the news, he hurriedly walked back.

"Your Majesty, the scholar of Hongwen Pavilion is already on his way over, and the book of Taixue will be delivered to His Majesty immediately."

Li An said respectfully.

"Oh, let me see."

Li Longji picked up the paper in Li An's hand and saw the echo from Hongwen Hall, and was immediately quite excited.

"Hongwen Pavilion is not far from Zichen Palace, there are a lot of young people in Hongwen Pavilion, if you trot over, it won't take long, you should be able to get there immediately."

Chen Xilie spoke.

Yang Guozhong didn't speak, his eyes unconsciously looked at the outside of the main hall, as long as the people from the Hongwen Pavilion came, he could immediately find that he was also quite looking forward to and curious about this machine.

As for Yang Yuhuan, who was quietly hiding in the wall, although she was a little wronged, as long as she could see the telegraph, she was also satisfied, and she also wanted to know if this telegraph really had such a magical function.

"Your Majesty, Your Majesty, Taixue is here."

A young Hongwen Pavilion scholar, holding a book of Taixue in both hands, ran towards the Zichen Hall with small steps, slightly out of breath.

"Come in."

Li Longji let the bachelor in and picked up the book of Taixue in his hand.

At this point, no one in the Zichen Hall doubted the magical ability of the telegraph machine to transmit information, and everyone was very surprised, and immediately realized the importance of this advanced machine to the Tang Empire.

"Zichen Hall is not very far from Hongwen Hall, if another telegraph is thousands of miles away, can the news really be transmitted? Also, wouldn't that require a thousand-mile-long wire? ”

Yang Guozhong asked.

Li An opened his mouth and replied: "The telegraph is inseparable from the wire, if the other machine is thousands of miles away, it does need thousands of miles of wires, as for thousands of miles away, whether it can also transmit news, you only need to prepare a thousand miles of wires first, connect between the two telegraphs, and you can know by experimenting, but, according to the principle, tens of thousands of miles are not a problem." ”

Seeing what Li An said, the emperor and all the ministers believed it, and they didn't have any reason not to believe Li An, after all, the preliminary facts were already in front of them, and they couldn't help but not believe it.

Li Longji was excited, and asked with great ambition: "Two telegraphs can be connected by wires, what if it is a three-day telegraph?" Can the extra one be connected with these two to deliver messages, and if one sends a message, the other two can receive it? ”

Li An knew that the emperor would ask these practical questions, and replied: "Your Majesty, three telegraphs can be connected directly, just like the connection of electric lights and wires, one sends a message, and the other two can receive it, if it is ten, then one sends a message, and ten can receive it." ”

"Li Aiqing, in this way, isn't it too chaotic, if the first station is sent to the second station, and the third station is sent to the fourth station, then how should the news be received?"

Li Longji continued to ask.

Li An knew that the emperor was not too easy to fool, but Li An was very clear about the principle of the telegraph, so that no matter what the emperor asked, Li An could answer very well, and he would definitely be able to satisfy the emperor.

Subsequently, the emperor and the ministers asked many questions about the telegraph, and Li An'an answered them 1510, telling everyone all the simple principles and knowledge of the telegraph.

A series of explanations took a full morning, and it was not until lunchtime that the emperor and the ministers finally figured out a general idea, but the excitement moistened everyone's hearts.

"I'm hungry, and all of you Aiqing must be hungry too! Someone came, and told the imperial chef to prepare more meals......"

Li Longji was happy and asked the imperial chef to prepare a large number of delicacies to express his great joy, not only the ministers could eat the delicacies, but all the technicians who entered the palace could all eat the most wonderful delicacies.
