"Ayer, how the hell did this thing do it?"

When you are called Aya by someone in his sixties, almost seventy years old.

That's sometimes......

Do you feel a little awkward?

But......

That's what is really going on now.

Li Angran and the others are now almost seventy years old.

Even......

Right!

From the outside, it feels older than Li Chongdu.

Li Chong said: "Now this is only a primary version, if you upgrade it again, I believe that there will be no problem at all to cover the entire Luoyang, even the suburbs of Luoyang." ”

After hearing this, several people were even more surprised.

But they didn't seem to answer their question.

Li Zhong then touched his chin again, and then said, "Forget it! Let's try to use it first. After all...... Whether it's good or not, you have to use it before you know. ”

Speaking of which......

Over the years, many people have also begun to work in the city, or to do business in other places.

The exchange of letters between the people, the merchants, and their families also became more frequent without realizing it.

If only they could take care of the business of sending letters and goods......

That......

To be honest, can this business also be done?

After all......

For the ancients, it was not very easy to send a letter.

Often, it has to be piggybacked by someone else.

It is said that there was once an official who wanted to take up a post somewhere else, and as a result, he was asked to carry hundreds of letters.

Of course!

Whether it was the dynasty or whether it was made up, Li Chong didn't know.

And then the words......

Is it possible to set up a radio in this barracks?

First, it can be used to convey military information.

Second, it can also be used to talk to soldiers and family members.

Of course!

Li Chong was afraid that their homesickness would be too strong, which would eventually lead to unintentional training, or even unintentional fighting.

Other than that......

This radio, it stands to reason, should be reported to Li Xiang.

Not......

Let Li Tian talk about it? Then Li Chong's eyes looked at Li Tian on the side.

Li Tian saw that he didn't know what he was thinking, and suddenly looked at him, as if he had a deep meaning.

Naturally, the next look was also puzzled.

At last......

After thinking about it, Li Chong arranged tasks for them one by one.

And new, wider-range radios are also constantly being researched and produced.

Although this radio was researched by Li Chong.

But!

When they were all gone.

When Li Chong was left alone, Li Chong was even more entangled.

Because you're going to use it, you're inevitably going to be known.

If it is known, will others be confused?

Li Tian should be asked to obtain a license from Li Xiang.

It's like a steam mill.

Permissions, only their homes, can be used.

But Li Xiang is not Li Er.

Li Xiang may not be willing to put this technology in their home.

Can't you get it......

Then they had to get married.

Of course!

In doing so, it seems that he doesn't trust this relationship between the monarch and the minister a little.

Other than that......

It is indeed too much abuse of this technology to be used for food delivery.

Let's take a look!

Let's see how Li Xiang reacts.

……

Luoyang Palace.

Li Tian entered the palace as if he was going back to his own home.

After asking the slaves and maids in the palace where Li Xiang is now, Li Tian quickly found Li Xiang and told him about the situation.

First of all, I said that I Aya has researched a very powerful thing, which can transmit sound for thousands of miles.

Let's be honest.

Just listening, Li Xiang didn't think it was shocking.

Even......

It may not feel at all.

But......

Next, wait for Li Tian to demonstrate to him.

In an open meadow, dozens of feet apart, in fact, it can be farther, but this is just for a simple test, so there is no need to run so that you can't see the figure, and finally, you can actually transmit the voice of the person on this side to the other side.

And the voice is relatively clear.

Then this shocked Li Xiang a little.

"You can't be a trick, right?"

Li Xiang said in surprise.

And Li Tian is on the other side.

"It's not a trick, it's a radio transmitter and receiver that I've only recently developed. Your Majesty, over there, can you hear clearly? ”

"Clear."

"That's fine!"

"How the hell is this done?"

"This ...... I don't know very well. ”

If you talk about the previous microphone speakers or something, they are all powerful.

Then this one is even more incredible.

After that, Li Tian said into the microphone again: "Your Majesty knows what is the use of this thing?" ”

Li Xiang thought about it for a while, and then said, "In the future, if I want to summon you into the palace, just use this directly?" ”

Li Xiang is not stupid, and he immediately understood the role of this thing.

Li Tian said: "You are not wrong to say so. But...... According to Aya, this thing can also transmit the sound to farther places, even to the Western Regions, for example, to the King of Zhao. ”

】

Li Xiang: "......"

After a moment of silence.

Li Xiang said again: "What you said is true? ”

Li Tian continued to say into the microphone: "Aya said yes, then it should be okay." After all...... Ayetha never lies. It's just that it's still being studied. ”

Li Xiang: "And then?" ”

Li Tian: "And what? ”

Li Xiang: "You Aya won't let you enter the palace just tell me this, right?" ”

Li Tian: "Your Majesty is Your Majesty." What to say about this thing, the secrecy may not be very good. Unless you say a code, say, a marching pot or something. ”

Li Xiang said, "What do you mean?" ”

Li Tian: "I don't know what it means to capture a marching pot." What Aya means is that the technology must be kept secret. Best, it's a family that controls it. ”

Li Xiang: "......"

Doesn't that mean let your family take control?

Li Xiang thought about himself, and then thought about the prince.

Anyway......

The prince and Li Shouyang also wear the same pants.

There's nothing wrong with that.

At least......

Before he died, there should be no problems.

As for what you said about the crown prince......

To be honest, then he can't control it, after all, he's dead.

Seeing that Li Xiang was silent, Li Tian also waited patiently for the other party's answer.

Li Xiang finally said: "Does this thing have any other functions?" ”

Li Tian said: "Then this thing has more effects......

If it was a normal king, it should be impossible to directly hand over such an important technology to the family.

Even if it is not divided and divided into several families to master a part of each, it will definitely be handed over to their children and grandchildren to learn.

But it seems to ......

Li Xiang didn't expect this at first glance.

Anyway......

Since it was researched by others, it is not a bad thing to control it for the other party.

Besides......

Next, they have to continue researching.

Although Li Xiang didn't think of it at the first time, Li Chong thought of it.

It's a pity......

You know!

This is probably only the eldest son, that is, the crown prince, the emperor and the grandson, may be able to grasp it.
