Yonglong six years.

The development of radio was quite rapid.

From the beginning of the transmission of only a few hundred meters, to cover the entire Luoyang, and even the suburbs, it only took less than a month.

And Li Chong's side is naturally calculating the relationship between the distance and the emission frequency.

And......

Is there any inevitable relationship with the shape of the antenna structure?

Because it seems that folding the antenna into different shapes will also affect the transmission distance and the quality of the transmitted signal.

And then this year.

The Princess's Mansion also has a lot of happy events.

Of course!

Strictly speaking, it shouldn't be a princess's mansion.

But......

In short, some of Li Chong's great-granddaughters and great-grandchildren are either married or started a family.

Li Chong also had to forcibly open for business.

After all......

After these two became husband and wife, they were not allowed to come to meet Li Chong, the great-ancestor.

On the day of the wedding, the scene was even more lively.

Although they have tried their best to control the scale, they can't help but have many families.

And then this specific object of marriage.

Li Chong didn't pay much attention to it.

After all......

Even if he pays attention, he doesn't necessarily know it.

Anyway......

Usually after the founding heroes, or the Sui Dynasty, or even the Northern and Southern Dynasties, they are already family.

What Li Chong didn't expect was that a few days after the wedding, someone came to the door and said that he wanted to ask him for advice if he had a problem.

Li Chongyi inquired, only to find out that it was a kid who came with this wedding.

He is only thirteen or fourteen years old, but he seems to like scientific research very much, and he used to live in Chang'an, so he has never had a chance.

This time......

Coming to Luoyang with your loved ones for a wedding, you don't want to miss the opportunity to ask questions.

Thereupon......

I dared to disturb Li Chong.

All I can say is......

This surprised Li Chong a little.

Because......

He usually doesn't recommend anyone to the top, so, usually, very few people come to visit him in the princess's mansion.

Li Chong also saw that the other party was a relative who came to attend the wedding, otherwise......

Li Chong asked him to go back to read Science Daily.

Of course!

It is also said that the other party likes scientific research very much, so he reluctantly meets the other party.

Thirteen or fourteen years old, I expected, the other party couldn't ask any difficult questions.

And then......

Li Zhong miscalculated!

This guy seems to have studied quite deeply.

Proper Xueba!

Well!

He could feel the aura of déjà vu from the other party's body.

Even though......

At this time, this scholar is still a little immature, and when communicating with him, he is also a little nervous.

After sending this guy away, Li Chong also asked others, what is the details of the other party? Others replied to him: "Xiao Langjun's name is Zhang Sui, his father is Zhang Sui, who was the county commander of Wugong County, and his great-grandfather is Zhang Gongjin, the founder of the Tang Dynasty. ”

】

Li Chong asserted: "This person should be able to get ahead in the future." ”

Of course!

Li Chong didn't say that the other party could be an official, a big official or something.

But......

This kind of performance like the other party is more suitable for roles such as astronomers and mathematicians.

He even asked Li Zhong a lot of astronomical questions.

He is also very interested in calculus.

It's horrible!

At the age of thirteen or fourteen, he was interested in calculus, so this is not a perversion, no, it is not a scholar.

And......

The other party has always been very concerned about scientific research, and the Science Newspaper is a must-read for him every month.

Although......

He didn't have that condition to really get in touch.

Don't look at his father as the county magistrate of Wugong County, and then you think that his family is very good, but in fact, it is ...... His father had died a long time ago, and in normal times, he still needed help from his neighbor's grandmother Wang's family from time to time.

This Zhang Gongjin died early in his thirties, and then the descendants did not have this umbrella, and naturally gradually withered and declined.

Then Li Chong felt that this person could be cultivated a little.

Of course!

If you want to say what to cultivate the other party and in which direction to cultivate, it can only be said that Li Chong doesn't know at the moment.

Wait until he and Silla have slept first.

Recent......

He did like Silla a little bit.

Because the longer she gets, the better she looks, not to mention, she also knows her preferences very well.

……

Wing Lung six years, the end of the year.

Angran Lee's food delivery business has been fully radio-based.

After the reasonable planning and distribution of the Fang City in Luoyang.

The efficiency of this food delivery business has also improved a lot compared to before.

Of course!

This should be artificial, or indispensable, it's just ......

It can make people run a lot less.

Through such a test, Li Chong can also find some problems in the use of the radio in time.

All I can say is......

Nowadays, radio is still a bit of a 'bulk' meaning.

If it can be integrated, make it more compact and easy to carry, then maybe it will be better.

So......

Next, Li Chong also set his sights on the research of dry batteries.

However, the research of dry batteries also involves the discovery of new substances.

Therefore......

It's going around and around......

Really!

I still can't escape this chemistry class.

Then Li Chong knew that it was time for Zhang Gongjin's descendants to study something.

Chemistry, of course!

It's just that......

To be reasonable, how to get the other party interested in this?

Because people may not be interested in this.

Thereupon......

Li Chong could only ponder it slowly by himself.

Give each other the periodic table of chemical elements, and then teach each other about chemistry.

This......

It doesn't seem to work.

The point is, how did you know this?

The scholar will definitely break the casserole and ask to the end.

And......

Xueba is not as good as a scumbag.

All I can say is......

It's a tough one.

Speaking of which......

He hasn't made electrolytic aluminum yet.

If you can make electrolytic aluminum, won't this plane be early?

Not......

I can only say casually ask.

Just ask him if he is interested in this search for ore and then discover new substances.

As for this, is the other party's talent in astronomy and mathematics in vain?

Li Chong can only say that this is actually not in vain.

After all......

No one says that once you study chemistry, you can't study astronomy and mathematics.

You can spend a little bit of time and then work on chemistry, maybe you can achieve something?

Thereupon......

Li Zhong called the other party over.

Propose to the other party to let him do a project, of course, all the money for the project will be paid by him.

In a word......

Next, what the other party has to do is to see if it can be electrolyzed and then find aluminum.

Then Li Chong vaguely remembered that electrolytic aluminum seemed to have to add cryolite or something.

Alas......

It can only be said that the subject of chemistry is a bit difficult.
