Seven years of Yonglong.

This is also the seventh year since Li Xiang ascended the throne.

This year, almost half of the railway from Chang'an to Shanzhou has been completed.

The various bridges and railways leading to Lingnan are also under construction at this time.

With the excavator, it is clear that this efficiency is much faster than before.

It's just that there are such things as excavators, and the number is still very rare at present.

There is still no way to completely replace manpower, so there are still a lot of conscription in the Lingnan direction.

Of course!

Most of these conscriptions were borne by the remnants of the former Goguryeo, Silla, and Baekje.

The words of the people of the Tang Dynasty are okay.

At least someone else bears the lion's share, and he only needs to be responsible for a small part.

And Li Zhong this year.

It also set a new goal.

In addition to completing the preliminary compilation of textbooks for each subject, and then while you can still move, you must continue to indulge in women.

Because......

If you don't have fun in time now, it is estimated that it will not be good in the future.

Silla is twenty-two and twenty-three years old this year, which is a good year.

And the first batch of widows at the beginning, at this time, was already thirty-four years old.

All I can say is......

It's not that Li Chongxi is tired of the old with the new.

But......

He's at this age, and if he has to deal with so many people, it's inevitably a little difficult.

So......

I simply stopped letting them serve.

Give each of them a glass rod and figure it out yourself.

In fact......

They didn't seem to be dissatisfied.

As for the ......

The two Tang slaves and maids given by Li Xiang.

Li Chong really didn't think anything about them.

In addition to listening to them play the erhu and pipa from time to time, what Li Chong asked them to do the most was to create the melody of the song he wanted according to his requirements.

The two were naturally surprised that Li Chong had such profound attainments in music.

Originally......

The two of them are also ready to be ruined, but they didn't think about it, and people didn't seem to be interested in them at all.

This also made the two even a little self-doubting.

Don't you look good?

Could it be that he can't even compare to that Silla maid?

For this matter, the two don't know whether to be happy or unhappy.

But the good thing is that ......

Even if they didn't sleep with Li Chong and didn't become Li Chong's women, there was no difference between eating and drinking and other people.

Anyway......

Usually I communicate music with Li Chong seriously.

Even......

Sometimes, when a certain instrument is missing, Li Chong will ask them to find someone they know.

After all......

They know more people in the court bureau.

……

January.

Li Chong conscientiously compiled the textbook.

February.

In addition to writing textbooks, Li Chong also took those widows out to play with Silla maids for a while.

March.

The textbook was compiled, a copy was made in the palace, and after it was approved, it was disseminated in the country.

But in fact, the textbooks are very rudimentary.

Maybe it's just physics, Li rewrites a lot, and the others are not good.

And Zhang Sui was obviously interested in astronomy.

Moreover...... He had never had access to a telescope before.

But now that he knows Li Chong, then Li Chong must be arranged for him.

It's not ......

One fifteenth night, he saw the moon in the telescope.

In astronomy, Li Chong also listed various evidences that are sufficient to prove that the earth is a sphere.

Even......

Li Chong also asked the craftsman to make a Foucault pendulum.

Be reasonable!

For example, the use of Foucault's pendulum to prove that the earth is a sphere, it can only be said that even Li Chong had to ponder for a long time to understand its principle.

】

Zhang Sui is different.

Li Chong just told him the principle once, and he already had a grasp of convenience.

Li Chong still didn't believe it a little, so he asked him to repeat it, repeat it over and over again, and sure enough!

The other party has clearly mastered!

So...... The comprehension ability of this scholar is very different from ordinary people like them.

This year.

In order to promote the development of physics.

At the same time, it is also necessary to compile textbooks.

In addition, his current research on electricity is already quite deep.

Thereupon......

It is also the creation of a new experimental device - "dot timer".

With this "dot timer", it is now more convenient to study the motion of objects or something.

All I can say is......

This is an experiment that anyone who has ever been in junior high school.

And when the students of Guozijian restored this experiment, they were also surprised by this kind of device.

Then during this period of time, Zhang Sui also asked Li Chong how the electricity came from.

At least......

He had to know how the electricity came from.

Although Li Chong did not explain the principle of essence to him, Li Chong also told him that in fact, electricity is generated through chemical reactions.

Moreover......

It can also be propagated by copper wires, etc.

Then Zhang began to draw inferences about the fact that electricity can be used to split water into two different gases.

He suddenly seemed to have grasped something.

So......

Is the essence of chemistry electricity at work?

Although......

He thinks so, too one-sidedly.

But......

If Li thinks about it, there seems to be nothing wrong with it.

And then......

For convenience, I pondered the relationship between electricity, fire, and toner, and iron ore powder.

Speaking of which......

What is the relationship between electricity and fire?

When he asked Li Chong this, Li Chong also gave him an experiment on using fire to conduct electricity.

But beware!

Fire is good for conduction, but ......

In the process of reducing iron ore powder by toner, the fire is heated through a glass tube.

There is no way for electricity to penetrate the glass tube.

So......

This again overturns the conclusion that electricity may be fire.

Following Li Chong's study, it can only be said that Zhang Sui can discover new things every day.

And when he went home, his aunt asked him what he had done today, and he also told his aunt all these things.

The woman looked at her son's gushing appearance.

I probably know what my son's future will be.

This is a good thing, and you will definitely not be able to pass the imperial examination.

But......

Doing these studies might not be a bad thing either.

After all......

Look at Li Chong, Li Chong is not an official in the DPRK.

However......

Li Chong is also respected.

The woman also thought that if she wanted to live a good life in the future, she would probably have to marry a princess.

But......

How can anyone like to marry a princess in this normal person.

That's the door-to-door husband.

That's all forced, okay!

Of course!

Marrying a princess can indeed ensure that you don't have to worry about food and clothing, which is true.

Otherwise......

Doing these studies really can't fill your stomach.
