Datang: Li Shimin begged me to rebel

This is an unprecedented gathering and an unprecedented celebration. There has never been such a celebration in Datang. Maybe it will become the norm in the future, but this year is definitely the most special year.

This is the first time, but it definitely won't be the last.

And for that day, Li Ke even did not hesitate to demonstrate the function of electricity for the first time, mainly by erecting large speakers on the relevant squares.Electricity is actually not a difficult task for Li Ke now. After the invention of the steam engine, the main source of human energy for many years to come will become boiling water.

Until Li Ke traveled through in his last life, the energy form of boiling water was still the mainstream. There are at least two ways of change that can be seen in the future, at least Li Ke traveled through.

One is that it is possible to use controllable nuclear fusion to directly cut the lines of magnetic induction to generate power, and it may become a mainstream power generation device in the future controllable nuclear fusion. Of course, Li Ke did not see it.

Another kind of Li Ke saw that it had already been manufactured, but it was useless to popularize it on a large scale.

That is the fourth-generation thorium-based molten salt nuclear reactor combined with the technology to promote supercritical carbon dioxide for power generation, and supercritical carbon dioxide replaces water vapor.

However, in Datang, Li Ke probably won't see the popularization of these technologies in his lifetime, and boiling water will be the mainstream way for human beings to obtain energy for a long time in the future.

Although the electric power Li Ke has not been launched in Datang, it is actually not difficult to make generators. It is estimated that in half a year at most, the first generator may be used in Chang'an City by then, and by then , it is estimated that Datang Everbright City will be the first place to adopt it.

The generator driven by a large steam engine is enough for the current Datang, and the difficulty of making it is not high. What Li Ke lacks is the popularization of basic subjects.

To be honest, the current Datang weapons and equipment can actually undergo further innovations, but Li Ke is not in a hurry.

There are several reasons, the first being that it is not necessary.

The large-scale armed all-steel armor combined with the large military crossbows that have been equipped to the squad, and the bows and arrows that have been popularized on a large scale, combined with the three-edged armor-piercing arrows, are crushing for the main enemy that Datang is facing now.

In fact, it is no different from the crush equipped with a rifle.

On the contrary, rifles are not even as good as bows and arrows. At present, the bullet production of rifles must not keep up. The main problem is gunpowder. Although there are basic industries, there is still a long way to go before the basic industries are fully popularized. It takes more than five years to train the first batch of technicians.

At present, Li Ke has started to build a large number of technical schools near all major cities in the Tang Dynasty, and then began to train the first batch of workers in technical schools.

If it is said that primary schools, middle schools, and universities cultivate the future of Datang, then technical schools cultivate the present of Datang.

Just like in the previous life, it was more pleasing to enter a technical secondary school than to enter a university. During this period, the popularity of technical schools is obviously higher than that of universities.

However, Li Ke is not prepared to make much change in these aspects. The advancement of society is regular. Although Li Ke can change, such changes that do not affect the overall situation are unnecessary.

In fact, the top group of people, in fact, have enough vision to make their own choices, and the cultivation of Datang by scientists will naturally not reduce the relevant efforts.

So in a short period of time, there is actually no need for any rifles or cannons, or in other words, the suppression power is not as good as that of bows and crossbows.

Because when the bow and crossbow lack arrows and arrows, you can use local materials, and even capture the enemy, but bullets can't.

The processing of gunpowder is not that simple, and gunpowder that cannot keep up with it may cause wrong effects, so Li Ke, a rifle cannon, is not in a hurry at all.

Let's put it this way, the normal historical development should be like World War I and World War II, when a war broke out, and then some technological reserves were transformed into brand-new weapons, and then quickly put into use.

But what Li Ke did was that he first brought the basic industry to the point of forming a primary industrial country, and in turn, when he carried out the reform of weaponry and equipment.

The speed of exploding equipment is much faster than it is now, because even if Li Ke gets out muskets and cannons now, Datang will not occupy the country's territory very fast.

Occupation is easy, but rule is difficult. If some territories are not fully prepared for rule, there is no benefit in occupying them. Instead, it is better to throw them to the enemy first.

What Li Ke is doing now is to first start reforming Datang, and the second is to supplement and strengthen the deficiencies brought about by the reformed Datang.

When Datang grows into a real giant, it's time to spread her influence.

But before that, Li Ke wants to set a goal and an example for Datang!

This gathering was a very important signal, so Li Ke also used the electricity that he had not used all this time, and installed speakers around the entire square and so on.

Of course, the speakers produced by Li Ke are incomparable and impossible to compare with the speakers of later generations. In fact, they are probably equivalent to the big speakers in every village in the past, but these speakers are enhanced through some technologies. Some equipment in the warehouse was used to make their sound transmission as consistent as possible.

Don't pursue the sound quality, there is no way to pursue it, these speakers are all cast in Datang.

Of course, Li Ke is definitely not doing these jobs to show that what he learned in college in his previous life has finally come into use.

In terms of power supply, Li Ke used two generators. The strategic warehouse has a backup generator, but it must not be a small backup generator. In fact, there are two lines here, and one line is connected to ordinary civilian electricity. Go to the National Grid.

Another power supply line is a special combat preparation line that is powered by a separate power station, which means that the entire city's civil power grid is powered off, and this power grid will not be powered off.

In addition, the important and large electronic equipment in the warehouse is equipped with ups, but that thing is completely different from the small ups in the office building.

So all in all, until now, Li Ke has found two 5kw gasoline generators in the entire warehouse, which are in the logistics warehouse. Li Ke doesn't know why these two generators are used. Li Ke pulled it out of the car in the parking lot.

The civilian strategic warehouse in his mind has no fuel reserves, that is a matter for military warehouses.But fuel is very useful, so their warehouse has an internal gas station.

But the internal gas station is located in the most independent and safest peripheral area of ​​the entire warehouse area. Unfortunately, it is in two different directions from the office building, so it is not unlocked yet.
