"Marquis Yong'an, if I heard correctly just now, is that gentleman explaining the principles of the telegraph to the students?"

When he came to the conference room on the first floor of Guanghua Building, Li Er motioned to Li Zexuan to close the door, and then he looked at Li Zexuan and asked.

Li Zexuan didn't know what Li Er was asking, but he still replied truthfully: "Your Majesty, what Mr. Mo said before is just the most basic theoretical knowledge used in telegraphs..."

"The most basic knowledge? What happened to the most basic knowledge? If the most basic knowledge is learned by foreigners, wouldn't it be possible for them to build a telegraph?"

Li Er interrupted Li Zexuan mercilessly, and he said with a gloomy expression: "I asked you to establish Yanhuang Academy to open up people's wisdom and promote engineering, not to let you leak my Tang military secrets. Tang's highest military secret, but you have so easily disclosed its principles to the public, have you considered the consequences?

This time, the imperial court sent troops to Zhengzhou, and before Cui Junchuo attacked Luoyang, the siege of Guancheng County was completed in time. In the subsequent battle of the siege, Li Jing and Liu Ren cooperated with each other and entered the city without a single soldier. what is it? You must know better than me!

It is conceivable that if the technology of the telegraph falls into the enemy's hands, how much trouble will it bring me to the Tang Dynasty? As the mountain chief of Yanhuang Academy, why didn't you think about this~? "

Li Er said a lot of "blah blah blah", and didn't give Li Zexuan a chance to interject in the middle. It was obvious that he was quite angry now.

It is precisely because of the recent war that Li Er has seen the important role of the telegraph in military and national defense, that is why he has such a big reaction now!

Seeing that Li Er had finally finished speaking, Li Zexuan hurriedly took the opportunity to say: "Your Majesty, knowing the principle of a telegraph is completely different from making a telegraph, just like people know that food is grown in the ground, but everyone Will they all farm? Of course not!

Chen introduced these to the students in the "Physics" textbook, so that they can recognize the characteristics of things in this world and broaden their horizons, so that they can create more valuable things in the future!

A wise man has a thousand worries, and he must make a mistake. Although the minister is proficient in engineering, the power of the minister is limited after all. The minister needs many inheritors of engineering to help the minister to overcome more technical difficulties and blindly treasure himself. Once the minister is old or dead, the engineering will decline rapidly and there will be no successor. what! "

Li Zexuan felt that it was necessary to explain the gap between theory and practice to Lao Li, and by the way, he changed the concept that Li Er had insisted on for a long time.

This question is actually very simple. In modern times, it can be said that 90% of college students, even high school students, know the working principle of telegraphs, but do they all make telegraphs? Obviously it is impossible. Among the 90% of the students, 5% can make telegraph machines!

Another example is atomic bombs, hydrogen bombs, etc. Many people know the principles of atomic bombs and hydrogen bombs, one is nuclear fission, the other is nuclear fusion, but so many people know the principle, why are there so few countries in the world with nuclear weapons? ?

There is a big gap between theory and practice.

A person who knows the principle cannot understand everything in practice. This is a completely different matter!

Li Er's expression turned a little darker, and he asked suspiciously: "According to you, even if all this knowledge is leaked to foreign countries, it will be difficult for our enemies to imitate the telegraph machine?"

Li Zexuan cupped his hands and replied, "Returning to Your Majesty, it's true, even if they figure out how to make a telegraph machine, by then, we may have produced a more advanced telegraph machine, with a longer transmission distance and better communication. Stablize!

Moreover, even though I say this, this knowledge is unique to my Tang Dynasty. At present, only the students of Yanhuang Academy are qualified to study, and the minister will also urge them to keep it secret. Students outside, or messengers from other countries, even if they enter the academy, they will not be able to see these knowledges!

What Your Majesty said today can be regarded as a wake-up call to the minister. In the future, the minister will strengthen the education of the academy students’ awareness of confidentiality, as well as the rewards and punishments. In the future, the admissions of the Yanhuang Academy will focus on examining whether the students are patriotic, and put an end to evil villains, infiltrating the academy, stealing Knowledge!

These things, the minister will list a charter as soon as possible, and then hand it over to Mr. Kong Gui and Mr. Wen Ji to strictly implement it, further preventing the possibility of the academy’s teachers and students leaking the academy knowledge! "

Li Er's complexion finally improved, he nodded and said: "Yeah! It's almost the same! Yanhuang Academy will definitely be the most important weapon of the country in the future, and I will take it seriously. !"

Although the Yanhuang Academy has only been established for less than a year and has not yet fully blossomed, Li Er can already see the important role of the Yanhuang Academy in the national power of the Tang Dynasty.

"The minister obeys the order!"

Li Zexuan arched his hands.

Li Er waved his hand and said solemnly: "Okay! Let's get down to business, I'm here today because I have something to tell you!"

Li Zexuan was puzzled for a while, and said, "Your Majesty, please speak!"

Li Er pondered for a moment, then slowly opened his mouth and said: "This time, to resolve the danger in Luoyang and break through Guancheng, the telegraph has played an extremely crucial role. The situation on the battlefield is changing rapidly, and the commander behind the enemy needs the latest frontline news, while the frontline soldiers need the commander. The latest order sent, the telegraph machine perfectly solved all the problems, this thing is simply an artifact of military formation communication!

The pharmacist mentioned to me in his report that he wanted to fully implement the telegraph in the army. I felt that what the pharmacist said was very reasonable. Therefore, one

, the telegraph machine needed in the army, Marquis of Yongan, see if you can think of creating another batch; second, no one in the army can use telegraph machine, or you let your students teach the sergeants telegraph machine How to use it, or you can send a group of students directly into the army to take charge of the telegraph! how do you feel? "

Hearing this, Li Zexuan frowned slightly. He did not expect that Li Er would be so eager to promote the telegraph machine. The problem is that the current telegraph machine is only in the experimental stage. If it is to be put into use on a large scale, there are still many problems to be solved!

"Your Majesty, the current telegraph technology is still immature. This minister recommends that you wait a little longer until the academy improves the telegraph before extending it to the army! Don't be too hasty!"

Li Zexuan arched his hands.

Li Er was a little unwilling and said: "When you say immature, you should mean that the current telegraph transmission distance is not far enough? But there is already a solution. This time Guancheng suppressed the rebellion, Li Yu was in Songyue. The top of the temple tower and Meng Wenhao on the fairy lanterns can transmit information to Chang'an City, which is more than 400 miles away. This is enough! After the big army goes on an expedition, just bring a few fairy lanterns with the army! "

Li Zexuan shook his head and said: "Your Majesty, using a telegraph machine at a high place to send telegrams can certainly increase the distance of transmission, but there are limits. As far as our existing telegraph machines are concerned, I estimate that these four hundred miles are likely to be the limit. The distance, no matter how far, is likely to be ineffective!

Moreover, every time you send a telegram, you need to climb on top of a very high fairy lamp, which is very detrimental to the concealment of the army! What if our army needs to sneak behind enemy lines? Could it be that a fairy lamp is still raised? Isn't that clearly telling the enemy the location of our army?

So please give your majesty some more time. The telegraph machine after the transformation of the academy will not only be able to transmit messages farther, but when sending telegrams, it only needs to be sent on the flat ground! Such telegraphs are more suitable for promotion in the military! "

After listening to Li Er, his face couldn't help but be moved. He asked uncertainly, "Can this kind of telegraph machine really be made?"

"Absolutely!"

Li Zexuan replied affirmatively.

Li Er nodded and said, "Okay! How long will it take you?"

Li Zexuan pondered for a moment and replied, "At least half a year, as long as a year, because the transformation of the telegraph requires searching and refining several special materials, so the minister cannot give His Majesty a very precise time!"

Li Er didn't ask Li Zexuan what materials he needed, because he knew that he would ask for nothing, and he certainly didn't have it, otherwise Li Zexuan would have directly asked him to borrow it instead of looking for it, so Li Er said directly:

"I know that you have sent people to search for various ore veins in the past. In the future, as long as it helps to make a telegraph machine, I can give you any ore! If you don't have enough people to search for ore veins, I can still do it. Appropriate to some of you!

If I remember correctly, there are two people in the Imperial Army who are brothers. Their ancestors were Taoist warlocks who specialized in finding dragons and acupoints. Although these two people did not learn the skills of family inheritance, they have also been to the vast majority of the Tang Dynasty. In most places, if you need people to find mines, I can send them to follow you and help you find useful mines all over the world! "

"Need and need! Your Majesty, to be honest, I don't lack anything, just manpower!"

When Li Zexuan heard the words, he was overjoyed. When he sent Ah Fu to Bashu to look for vanadium mines, he was thinking about getting a team dedicated to finding mines, but he never found the corresponding talents. Bring him warmth.

This warmth is so timely!

Li Er couldn't help but smile and said: "Okay! I will let them come to you when the time comes! One of these two is called Liu Feng and the other is called Liu Yun. In addition to being well-informed, the two of them are also good at kung fu. They will help them in the future. After you find the ore veins, stay here as your guard! You and the Yanhuang Academy are very important to the Tang Dynasty, and there must be no mistake!"

"Ah~?"

Li Zexuan was stunned when he heard the words, and he quickly waved his hand and said, "Your Majesty, you can't do it, you can't do it! The two of them are the imperial guards, how can they be the guards of the ministers? Please take your majesty back!"

Before Pang Feiji's investigation of the whereabouts of the "Taibai Four Ghosts" failed for several months, Li Zexuan thought about expanding a group of guards. Although he was indeed lacking guards, he couldn't use the Imperial Army as a guardian. You must know that the Imperial Imperial Army is equivalent to The emperor's personal guard, it would be taboo to serve him as a guard!

"It doesn't matter! You just need to improve the telegraph as soon as possible. If this happens, I will protect the honor of Yanhuang Academy for all ages, and be with the country!"

Li Er waved his hand and said indifferently.

After all, he left without caring about Li Zexuan's reaction!
