After talking, when it came to today, it became what it is now, not only the members of the Tang clan and the royal family who could come to participate participated, but also the ministers of the imperial court who were in Chang'an, and they were not left behind.

In addition, the scale has not been expanded, the problem is that there is no need to expand, all the ministers of the court have come to participate, which means that almost all the gate valve families in the world know that they have participated in this ceremony.

Although it is a little different from Li Ke's original idea, just like Li Shimin said, after the entire ceremony of the crown, no one really felt that there was anything wrong, even Li Tai and Li Zhi felt that it was normal.

It seems that Lao Li's idea is right, and his previous high-profile character design is really deeply rooted in the hearts of the people.

But it doesn't matter, anyway, it's just like this once in a person's life, it's impossible to marry a wife every year, all the big things that should be done this year have been done, and there will be no big things left.

After the completion of the crown, Li Ke is about to leave for Qinghai, and when he arrives in Qinghai, it is basically late October, and it is about to enter winter, this year he is destined to spend the New Year in Qinghai, which can be regarded as the completion of Li Ke's original promise to many Qinghai people.

But before leaving, Li Ke has one more important thing.

That is to solve the trouble raised by Li Shimin.

I have to say that what Li Shimin put forward is very reasonable, and if someone dares to publicize this kind of thing in the name of Li Ke in a locality, it will easily cause a huge riot.

Even if such a riot was dealt with in the end, it was also a major impact on the development of the Tang Dynasty, as well as on the reputation of Li Ke and the Tang royal family.

After all, some rumors spread, and it is even more difficult to eliminate them.

Spread rumors with one mouth, refute rumors and break your legs. This is true more than a thousand years later, let alone in this ancient world?

So the best way to avoid one thing from happening is to strangle everything in the cradle, and the solution to this is very simple! That's the speed at which information is delivered and converted!

For others, such a thing may not be solved in this era, but for Li Ke, it is not difficult.

Quite simply, the radio station can solve this problem, and as for the problem of communication distance, it is not a problem! In terms of the cleanliness of the electromagnetic waves in Datang's current atmosphere, it is estimated that the modern transmission of the hand, which is 3 kilometers away from the plain, can reach about 5 kilometers in Datang.

A clean electromagnetic environment is too much of an impact.

As for Li Ke, although Datang's industrial system can already make radio, Li Ke did not guide in this aspect, mainly because it is not easy to learn the pre-discipline of electromagnetism, and there are not many students trained in this area.

According to Li Ke's estimates, it will take at least five to six years to reach the radio station.

But it doesn't matter, who let us hang it.

Li Ke hadn't paid attention to the warehouse in his mind for a long time, but the warehouse was still expanding steadily, and the warehouse on the ground had unlocked several large warehouses, but all of them were filled with grain.

In addition to high-yield wheat, it is ordinary rice, but it is of little use to Li Ke, because rice is a grain reserve, not a seed reserve, which means that they basically cannot be left for seed.

Although the data of these grains is very large, it is useless, and now Datang is not short of grain, what is the use of taking out these grains?

However, the warehouse on the ground did not unlock anything useful, but the underground part still had something completely new, such as a radio station.

Li Ke has also seen that there are air-raid shelters, grain, and so on, which are completely built in accordance with an underground permanent air-raid shelter.

And the things that are stored in this are naturally available from all sides, and the radio station is the latest warehouse to be stocked, not a modern radio station.

Rather, it was the end of World War II, or the radio stations that were produced based on modern production technology similar to those of the Second World War era, both small and large, with hundreds of sets in total.

All the electronic components of these radio stations are tubes built with special modern technology, and these tubes are also wrapped with a special electromagnetic radiation protection film.

There are also special protective shielding boxes on the outside of these elements, which are also grounded with special devices.

As can be seen from these protective measures, all the equipment here is designed to protect against electromagnetic pulse bombs.

For example, the nuclear electromagnetic pulse bomb uses the neutron bomb after the nuclear explosion to interact with the atomic nucleus of a certain material to instantly release high-energy γ rays to destroy all electronic equipment.

After all, the killing radius of a strong electromagnetic pulse formed by the explosion of a special nuclear bomb with a million-ton yield at an altitude of 400 meters is about 2,000 kilometers, and the electromagnetic pulse is pervasive.

In a sense, this thing is almost the best choice after the outbreak of nuclear war in modern times.

Because its destructive power is much greater than the direct lethality of nuclear bombs, and the degree of destruction of modern civilization is also much more terrifying.

The communication device equipped with the protection electromagnetic pulse bomb appeared here, and Li Ke did not feel any surprise.

You don't know how many of these things there are in the country, not to mention that this is a strategic reserve warehouse, which itself can be regarded as a key "taken care of" object.

Li Ke didn't plan to take out this thing, because what's the use of taking it out? For this era, trains are already plug-ins at the level of plug-ins.

After this radio is taken out, isn't it a super plug-in? Although it is said that Datang will have it in a few years.

But Li Ke finally took it out, the reason is very simple, the scene that Li Shimin described to him before really scared Li Ke.

He didn't want his influence to be used, and Li Ke knew the terrible consequences of this kind of use by others, he knew it better than anyone else, so such a thing must be prevented.

And the best way to prevent it is to ensure communication with Chang'an.

Therefore, Li Ke held the map of Datang and studied it for a long time, according to the description of the large radio installations here, if the antenna towers tens of meters high were built outside, these large radio stations could almost radiate thousands of kilometers in radius.

Consider that in those days, domestic radios often received Soviet radios, and you can see the coverage of this thing.

And Datang's electromagnetic environment is so clean, its coverage is naturally unparalleled.

And Li Ke also thought about it, although he took it out, but as a secret means of guaranteeing the bottom, it is not easy to use it, it is the top secret of Datang's top secret, and normally it is still in accordance with normal communication, so as to let the industry develop normally.
