Nineteen years of Yuan Heng.

At this time, the five widows were all adults.

But......

It doesn't matter if you seem to be an adult.

Anyway......

As early as when they were not yet adults, Li Chong had already asked for them.

this year.

The railway from Liaodong to Yingzhou is also repaired.

This means that the connection between Datang and Liaodong has become a lot closer.

Although it is true!

Sea freight is no worse than land transportation at all.

But!

The point is, sometimes it freezes on the surface of the sea.

This is a bit unfavorable for the Liao State to transport their goods to the Tang Dynasty.

Before building this railway, Li Chengqian also asked Li Chong's opinion.

Say if you want to fix it.

After all......

The impact on Datang must be huge.

Li Chong felt ......

Anyway, it's the money and people from the childish slaves, so let's fix it.

When the time comes......

If you really want to fight with the slaves, it is equivalent to sending them a railway for free.

In fact......

The relationship between Datang and Liaodong has always been very good.

It's just that......

Sometimes, this brother has to settle accounts.

Li Chengqian is also a little worried, in case the slave dies at that time, what if the later people have a bad relationship with the Tang Dynasty?

Li Chong felt ......

This problem can be solved by the third generation.

Now......

This is not at most the first or second generation.

It was the slave who built the railway, and he must have done it in order to dump his goods to the Tang Dynasty.

Li Zhong thought that in the future, this thing that entered the customs must also be well controlled.

Take what you need as much as you can, and don't take advantage of anyone.

Otherwise......

There may be a real war in the future.

Of course!

If you really want to fight, the child slave may not be able to fight.

After all......

The formula of this gunpowder has always been under the control of Datang.

The other party needs it, and Datang temporarily matched it for him.

this year.

After recalling, Li Chong also drew a general appearance of the excavator for the Academy of Sciences.

The excavator uses the principle of hydraulics.

Hydraulics can also be used in the waterproofing of ships.

In the past, the sealing requirements were not high, so this hydraulic pressure was basically useless.

But now......

This hydraulics is also going to start researching.

Especially after the large quantities of rubber trees were retrieved from South America.

Other than that......

Nowadays, more and more precise machining also provides a good prerequisite for the birth of hydraulic devices.

I saw the Liaodong Academy of Sciences.

Everyone stared at the excavator that Li repainted.

Basically, they understand how the spoon moves.

It's just that......

How do you make it move like that, that's the problem they're trying to solve.

Now you have the mass-energy equation and a small piece of uranium-235 in front of you, so well, you are now going to start building your own atomic bomb.

But......

Li Chong's whimsical ideas still made them have to admire.

After all......

Why didn't they think of such a powerful thing?

In fact......

You can build an excavator without hydraulics, after all, the excavators in the small park have been seen and even played. ….

But!

To achieve practical results, it is better still

Go in the direction of hydraulics.

And......

This is also of great help to the subsequent construction of steamships.

Of course!

The former uses hydraulic pressure to convert into mechanical energy, while the latter is just for leak prevention.

Again, the purpose is very different.

In the middle of the nineteenth year of Yuan Heng.

Li Zhi announced that a large island in the sea southeast of the Tang Dynasty was now his.

In order to completely occupy this place.

Li Zhi also carried out the immigration of the place.

How to say it.

Anyway, they are all the people of Goguryeo, Baekje, and Silla, so it can only be said that Li Zhi is not distressed at all.

And then......

Finally, a small number of Han Chinese officials were sent to govern.

Don't talk about it!

The island is quite rich in natural resources.

Even......

There are also precious woods such as ebony and sandalwood.

In this way, in the future, if Liao wants to get ebony and sandalwood, maybe they don't need to buy it from Datang.

After occupying this large island, Li Zhi's exploration of this sea area did not stop there.

Instead, it continues to allow people to explore their surroundings.

Anyway......

He who has been there belongs to him.

This is especially true for the small islands to the east, but they are not to be ignored.

What we need to do now is to ask professionals to explore the map or something, the wind and waves at sea, and so on.

Li Zhi is a sincere person.

Unlike Li Tai, he sent people to Australia without saying a word to Li Chong.

After Li Zhi asked people to roughly draw the map and give Li a second glance.

Li Chong felt ......

This place is often exposed to typhoons, right?

All I can say is......

Let's take precautions to protect it.

In fact......

Not only this island, but other islands can also be occupied.

Just of course!

The other islands must have more populations than in the Philippines.

Affected by the war, in the past two years, Li Xin's maritime trade has been more or less unsmooth.

[The problem of slow update of new chapters is in the can.]

Let's take it back.

As for when it will be taken back.

Li Zhong is not easy to say, maybe years, decades, or hundreds of years?

At last......

Li Chong didn't bother to think about it.

In a word......

Let's first repair the railway from Luoyang to Guangzhou.

Only with the railways can Datang control more, bigger and wider territory.

Other than that......

The railway from Chang'an to Shanzhou, that is, to Tuyuhun, has also begun to be put on the agenda.

The main thing is that if Datang really wants to run the Western Regions next, this road must be built, so that it will be easier to control the Western Regions.

It's best to be able to repair to the Anxi Metropolitan Protectorate, at least no matter what, you have to do it to this extent.
