Communication has a very great significance in any era, this is the basis for contact between people, if there is no communication, there is no way to contact people, they will all live in isolation, human civilization will not be able to develop, let alone brilliant achievements, estimated, the same as the current wild animals.

For example, after the wolves find food, they will howl to greet their companions, so that their companions can join them as soon as possible and share the delicious food together.

Human beings in the early days, the means of communication mainly rely on the voice roar, compared with the wolves there is still a gap, not to mention others, but human beings are also the smartest, after the development of civilization from generation to generation, the means of communication are more and more advanced, in ancient times, there were stagecoach communication, flying pigeon to pass the book, the wild goose to pass the book and other faster means, and in modern times, the emergence of telegraph and telephone, it completely subverted the early means of communication of human beings, so that communication became faster, almost no need to wait for time.

In ancient times, 800 miles was urgent, but only a day could send news out of a distance of 800 miles, and in later civilized societies, a mobile phone could be used to get in touch with the other party immediately, which was too convenient and fast.

When the telephone first appeared, only the government and particularly wealthy people could afford to use the telephone, ordinary people could not think of it, and with the development of the times, soon, the most common poor people can also use the telephone, moreover, it is a mobile phone, and the function of the mobile phone is becoming more and more powerful, all kinds of functions are available, very convenient and fast.

After fast communication, there is a great benefit, that is, it promotes the connection between people and avoids the generation of this emotion.

For example, before the popularization of mobile phones and telephones, after a person left home, if he did not come back for a year, then the people at home could not know his specific situation, and even, whether the person was alive or dead was not clear, and the anxiety in his heart was feasible, and this is what concern meant.

However, in the era of developed communication, there is also a disadvantage, that is, communication is too frequent, people can contact each other anytime and anywhere, the emotion of missing is gradually forgotten, and even, many people can't feel what kind of taste it is to miss at all, and the lack of this emotion is also a pity for human beings!

However, no matter what, the development of advanced means of communication is the progress of the times, is the general trend that no one can stop, although in the development of advanced communications at the same time, will cause certain bad consequences, but on the whole, the benefits outweigh the disadvantages, from the full support of the court and the emperor can be seen, everyone is full of expectations for this subversive invention.

Once a new means of communication appeared in the era of the Tang Dynasty, it is difficult to describe the development and promotion of the Tang Empire, which will save a huge amount of materials, thereby promoting the development of the Tang Empire in a better and faster direction.

Just imagine, the entire Datang official news transmission, need to use a huge post station force, the consumption of resources to the imperial court is not small, in addition, the speed of the post station to transmit the message is still very difficult, even along the railway line deployment of the post station, the speed of transmission of news is difficult to compare with the telephone, and as long as there is a telephone, these post stations can basically be canceled, the various decrees of the imperial court can also be conveyed more quickly, thus greatly saving administrative costs, as for the investment in laying and maintaining huge telephone lines, In the face of these benefits, it seems very insignificant.

It is precisely because of so many benefits that all the ministers and people who know about the Wanli Transmission Plan are very supportive of Li An, and some ministers and people who oppose this plan are not opposed to the plan itself, but feel that it is too difficult to achieve, it is simply a fantasy, if the experiment fails, it will not cost a lot of resources of the imperial court in vain.

And because Ang Lee has done so many miracles, on the whole, most people believe in Ang Lee and support the plan, as long as a few people are skeptical.

"Li Shilang, are you going to the R&D center?"

Li Yu quickened his pace and caught up with Li An.

Li An nodded and said, "Yes! Recently, I have encountered problems in a row, and if I don't go there in person, I'm afraid the craftsmen won't be able to solve them! ”

"Li Shilang's 10,000-mile sound transmission plan can really succeed, in Chang'an City, you can directly talk to the people in Luoyang City, and you can still hear the other party's voice?"

Li Yu looked a little incredulous.

Li An looked at Li Yu with a displeased face, and said, "King Guangping has no confidence in me so much, is this difficult?" ”

After speaking, his face was relaxed.

'Is it hard?' Is this still a normal person? ’

Li Yu complained in his heart, as soon as he thought of being able to talk directly to the people in Luoyang City, Li Yu felt incredible, which was also outrageous.

Although some shocking inventions have been made before, such as trains and airplanes, these inventions are a bit small compared to the Wanli Transsin Project, and they are not at the same level at all.

For example, although the train is much more advanced than the carriage, it is also running on the ground, which is based on the rationalization and improvement of the carriage, and although the plane is more powerful, it is said that Lu Ban has also made mechanical items that can fly in the sky, and the principle of the aircraft is not much different.

Although in the ancient environment, these are all strange and ingenious, and they are all things that cannot be put on the table, but as these items invented by Li An are too powerful, they are of great use to change the lives of the people of the Tang Dynasty, so that no one dares to underestimate these so-called strange skills and tricks, and regard these as very practical and important technologies, and even, the imperial court agreed to open classes, so that the children of craftsmen can learn these techniques from an early age, so that they can invent more and better items in the future.

Looking at Li Yu's surprised eyes, Li An looked a little unimpressed, this kind of expression is too common, it can't cause Li An's slightest psychological fluctuations, he smiled faintly, and said, "Is there anything wrong with King Guangping?" ”

Li Yu opened his mouth and said: "Yesterday evening, Shi'er suddenly wanted to go to the mountains outside the city to play, I asked why, he said that Li Shilang talked about a lot of flowers and trees in class, there are no in the Daming Palace, I specially asked the waiter, sure there is such a thing, and Shi'er and the waiter have been looking in the Daming Palace for a few days and have not found it, hahaha!" ”

At the mention of his son, Li Yu laughed unconsciously, and it could be seen that he was very happy.

"Haha! Shi'er is a very serious student! However, I talked about a lot of flowers and trees, some of which are not available in the entire Tang Dynasty, and some of them are not of good quality and noble enough, and cannot enter the palace. ”

Ang Lee replied with a smile.

Li Yu nodded and said, "What Li Shilang said is that it will be time to teach the children in two days, why doesn't Li Shilang pull the class out of the city?" In this way, they can see the grass and trees outside the city for themselves, and they can really understand, don't they? ”

When Li Ang heard this, he felt that it was too right, nature is the best teacher, taking students out to play, isn't it an outing, you can go out in spring, and you can also see different charming scenery in autumn, and the benefits of this are also obvious, so that children can feel the wonderful scenery of nature up close, so as to be full of love for life.

And because the outing needs to climb mountains and wade through water, it is a more physically demanding thing, so it can also test the children's physical strength and endurance, test their willpower, and be very good for their future.

Since the outing has so many benefits, Li An naturally has no reason to object, and the only problem is the problem of safety, if you only take Li Shi to the outing, a dozen guards are enough, but if you take a large group of imperial grandchildren to the outing, the security pressure cannot be easy, in addition, there are too many imperial grandchildren and guards, in order to ensure safety, it may be necessary to close the road along the way, thus interfering with the normal life of ordinary people.

In short, ordinary people go out for an outing or something, there is no pressure, you can set off at any time, but the emperors and grandchildren go out to play together, there are more things to consider, any detail is not taken into account, it may lead to accidents, for example, ordinary people go out for an outing, it doesn't matter if they fall or something, but if the emperor and grandson fall, it is a very serious problem, not only the emperor and grandson themselves are guilty, the attendants must be punished, and the guards are indispensable to be punished, Even Ang Lee, the organizer, has to be criticized to a certain extent.

However, no matter how difficult it is, Li An is not afraid, as long as all the work is arranged in advance, there will be no major problems, let alone any potential safety hazards, as for the abrasions caused by occasional falls, Li An is also fully capable of resolving them.

"King Guangping's proposal is very good, and I personally support it, but should I tell Your Majesty about this matter?"

Li An nodded and spoke.

"Li Shilang, don't worry, I'll go and tell the imperial grandfather about this matter, I believe the imperial grandfather will agree."

Li Yu said.

"So, that's great, gather at the gate of Daming Palace early the day after tomorrow, let's go on an outing together and say goodbye."

Li Ang doesn't have much time to talk to Li Yu, and there are still many things waiting for him in the R&D center? Especially today and tomorrow are the best time for Ang Lee to solve the problem, and Ang Lee also fully believes in his own strength to be able to solve this problem before the day after tomorrow, and then let the craftsmen start to produce experimental-grade products, so as to promote the further development of the Wanli Transsion project.

Yang Guozhong put down all the affairs at hand, bought some gifts, and quietly ran to Li Linfu's mansion, he had something very important to discuss with Li Linfu, he believed that Li Linfu was about to die, and he should be able to release his past suspicions with himself, after all, they now have a common enemy, and Li Linfu is a person with a sweet mouth, and he will not be as dead as the prince, and he will never reconcile with himself.

However, since you want to give gifts, you should also give some more expensive and high-grade ones, and Yang Guozhong's stingy personality is also revealed at this time, he didn't give any valuable things, so he gave a very ordinary snack, five copper plates and a big bag, it should be said that it is a dessert, it is for children to eat, however, the elderly also like to eat, in fact, it is also a good small gift, but it is generally a gift item for ordinary people, and rich people do not look down on it.

And Yang Guozhong, as a big official in the current dynasty, has a number of money-making industries, so he is naturally not a poor ordinary person, he casually takes some snacks and gives gifts, which does seem a little shabby, which is simply disgusting Li Linfu.

However, Li Linfu is about to hang up now, it is indeed not particularly worth investing, everyone is just a relationship of using each other, no one owes anyone, why do you want to give a big gift, besides, people are dying, give too big a gift, Li Linfu can't afford it, just buy a small snack.

"Yang Yushi, why are you here?"

The housekeeper Li Zhonglin had just come back from buying medicine for Li Linfu when he saw Yang Guozhong coming to visit.

Yang Guozhong didn't bother to be polite to a subordinate, and said directly: "Go and tell the right minister that Yang Guozhong is coming to visit." ”

"Yes, Yang Yushi wait a moment."

Although Li Zhonglin had some opinions about Yang Guozhong, at this time, he did not dare to slack off, and directly trotted to report.

At the beginning, when Yang Guozhong was against Li Linfu, he hated Yang Guozhong to death, and felt that this person surnamed Yang was an ungrateful villain, who actually betrayed the people who promoted and helped him, but at this moment, Yang Guozhong's status is in full swing, and Li Linfu is about to hang, so he naturally does not dare to be angry, let alone offend Yang Guozhong.

"Ah Lang, Yang Guozhong is here."

Li Zhonglin even put aside the medicine instructed the people below, and ran directly into Li Linfu's bedroom to report the situation.

"What, Yang Guozhong is here, what is he doing here?"

Li Linfu and Yang Guozhong have been at odds for many years, and no one will let anyone, but on the road of framing the prince, they have always cooperated very well, and in addition, the two sides are almost enemies.

"Ah Lang, Yang Guozhong seems to have come to see you, and he still has a gift in his hand?"

Li Zhonglin opened his mouth to guess.

"What, with a gift, really came to see me?"

Li Linfu frowned slightly, thought for a while, and asked, "Zhonglin!" Is there something going on in the court today? ”

With the sensitivity of a politician, Li Linfu felt that this matter was not simple, Yang Guozhong would not come to see him for no reason, there must be some reason.
