This grand future scene makes Li Er and others inexplicably excited, but after all, these are just ideas now, just imagination.
But to implement these ideas and turn your imagination into reality, there must be a process anyway.
This process may even be quite lengthy, but...
Li Er is also confident.
Nowadays, Datang has a good environment. It should be promoted, so there is no need to worry too much.
Everyone deliberated for a while and nodded.
Li Er...
As well as Wei Zheng and his group, they all came out of the heap of dead soldiers and belonged to the founding team. In fact, it is not easy for them to feel "daunted" or even just a little bit discouraged.
In fact, although Li Er and Wei Zheng, the emperor and ministers of Tiance Mansion did decide to start the construction of telephones, but...
No one made a hasty decision, and everyone knew that they needed to discuss it seriously.
The reason is very simple... The main difficulty in the construction of telephones in Mobei lies in the foundation.
It's not easy for the cavalry to come and go, let alone the engineering team? This construction task is indeed difficult to handle.
It was also because of this that Li Er withdrew a large number of troops, which was actually done in stages.
First, move some distance south, so that you are closer to the inland, and you can save some of the transportation costs of grain and grass baggage.
This is first of all, use this savings to save the construction cost of the telephone - at least the upfront cost.
The second is for the army to continue to pull back, another hundred or two hundred miles, to see how the frontline projects are going.
If everything goes smoothly, then we can continue - in short, this matter must not be rushed or delayed - after all, withdrawing troops is considered a military operation, which also has additional costs, but we cannot rush it.
So the whole thing needed to be controlled at a certain pace, but fortunately it was settled smoothly in the end.
Now it's time to set up a new phone line...
From Jiangdong to the northwest.
Then from the northwest, to Hedong, then to Jiangdong, and then to Lingnan.
In the northwest direction, obviously the most critical nodes are the area between Guanzhong and Yizhou. There is nothing to say about Youzhou in Hedong, and Hangzhou is naturally in Jiangdong. Needless to say, Lingnan is the recently built large city Zhongzuo Suo.
It is already very difficult to build one or two telephone lines in such places, and if they are to be built with commercial value, it is even more necessary to build many more lines——
What is the specific number of additional construction? This cannot be explained clearly in a few words. Anyway, it is definitely much more than the fifty military channels in Mobei.
And so many phone lines...
First of all, the number one problem is how to ensure that there is no chaos, and... If you think about it, you will know that the original telephone is of course incomparable with the telecommunications systems of later generations. It can be assumed that the original simple dedicated line is already Zenith Star Technology, then...
If a businessman in Hangzhou wants to know the price of sheepskin in Lingzhou, he might be able to call Lingzhou directly.
But if businessmen in Lingzhou want to know the prices of silk and sugar in Suzhou, they can only set up an office in Hangzhou at this time and let their people stay there at any time to inquire for them. And this...
All of this is actually quite troublesome. Modern telecommunications systems are something similar to air and water to modern people, but without these, a lot of costs will appear invisible.
In addition to these, there is another fatal problem. The "signal line" invented by Li Sheng requires copper, and copper... this thing can be melted and cast into copper coins!
Even if it cannot be made as accurately as copper coins, even if it is just melted and cast into copper blocks, the value will not be much different. This is more troublesome, because some people among the common people will steal copper to make money.
With such a long line, how can we prevent such a situation?
In short, the whole thing is just four words, with thousands of threads.
Other questions, such as there are a large number of merchants in both Lingzhou and Hangzhou, can so many merchants only use one line? This is definitely not possible...
Then we definitely need to build a few more lines.
How many should these be? It sounds like the more the merrier, but now it’s really confusing...
When faced with really difficult things, people can't even simply pursue KPIs. This is the most troublesome thing.
But after some discussion, Li Er and others decided on the matter.
"...Whether our Tang Dynasty can survive for a long time depends on the present..."
As the carriage entered the palace, Li Er murmured to himself!
The future is uncertain, but he must keep doing things. As long as it is useful to Datang, he knows that he must push forward.
but……
"Your Majesty, there is no need to worry. This is a good thing after all. It is just a matter of how good it is. Now that the world is peaceful, Your Majesty must take care of your health!"
Du Ruhui saw that Li Er looked a little haggard after being excited, so he couldn't help but remind him.
The level of the king is still very important to the fate of the country. How many dynasties have overturned on the issue of power transfer since ancient times? No matter how awesome Li Er is, his health is still very important. But Li Er smiled and didn't take it seriously.
He waved his hands, and then his expression showed a bit of embarrassment and a look of emotion.
"Of course I know about taking care of yourself. In fact, you guys do too. I have nothing to worry about. With Sheng'er here, what danger can we face in Datang? Hehe..."
Li Er smiled proudly, but this smile was a bit embarrassing, and then continued, "Now the world is peaceful, and the Tang Dynasty's national power is accumulating rapidly, which can be said to be changing with each passing day... But all of this is almost because of me, a kid like me.
His handiwork. Since I am the king’s father..."
"I have to do a few things for my children in the future, otherwise how can I show my identity?"
Li Er chuckled, sent Du Ruhui away, and went into the palace.
In the following months, Li Er's palace, the Tang Dynasty's court, and the emperors and ministers became busy again.
Of course, this busyness is mainly due to preparation work in various aspects.
To establish a telephone communication line, the first thing is the telephone itself, the hardware...
The structure of the original telephone is of course very simple. Even if the average person does not understand the principle at all, it is still possible for craftsmen to repair and maintain it according to the instructions prepared by Li Shengming.
And this is only one aspect, it can even be said to be a relatively simple one.
Just like on the battlefield, it is cool to fly airplanes in various tricks, but the real test is always how far you can repair the airport. The same is true for telephones.
To lay the signal transmission line, not only the amount of work was huge, but also there were many obstacles... Of course, as this matter was related to the overall political and economic prospects of the Tang Dynasty, Li Erjun and his ministers pushed hard, and of course it was carried out.
It's just that such a big thing is quite eye-catching...
