Thirteen years of Yuan Heng.

Li Tai established diplomatic relations with Da Shi.

All I can say is......

It's not easy to get here.

This also means that the exchanges between the East and the West are about to become more and more in-depth.

Unlike Datang, the big cannibal is actually very protective of business.

Since Li Tai is here to do business, they naturally protect these people.

Li Tai's side......

In addition to establishing a trade relationship with the Great Cannibal.

Next, this south, for the exploration of Australia, did not pull down.

Of course!

If he could, Li Tai even wanted to annex all these large and small islands and small countries along the way.

It's a pity......

This inconvenient transportation and inconvenient rule is one thing, and others will definitely not obey them, and another aspect.

Merely......

It's okay too!

And sometimes, it doesn't have to be all of them.

With a lot of porcelain and silk obtained from the Tang Dynasty, Li Tai exchanged a lot of Kunlun slaves from the southern islands.

It's still okay to use these Kunlun slaves to help you grow land or something.

Let Kunlun Nu help with farming.

And then the rest of the people are in charge of production, or they simply get on the ship and follow the maritime trade.

Although Cochin has not carried out large-scale agricultural mechanization, it is estimated that this manpower will be okay if it is replaced with a little more.

Now Li Tai feels that there are a lot of things to do, but he doesn't know how to start.

Tell me about Li Chong.

Obviously, Li Tai already has a bit of selfishness.

Li Tai planned to establish a system in which all overseas countries would pay tribute to him, with himself as the center.

If he said this, wouldn't it threaten Datang's interests and expose his own ambitions?

】

Datang shouldn't watch him sit big, right?

In fact......

There will indeed be such a problem.

Merely......

Liaodong is sitting like this now, and Datang actually didn't say anything.

……

Thirteen years of Yuan Heng.

Spring, March.

Liao's fleet began its first attempt to cross the Pacific Ocean.

All I can say is......

The road went relatively smoothly.

From west to east, the flotilla went for almost a month.

Along the way......

None of the major problems were encountered.

Merely......

This sky and sea are really a little lost and dazed.

Fortunately, they are still able to determine their position and know what to expect, otherwise......

It's hard to say where exactly this has gone.

The first time I went out, I only walked for a month, and then I came back.

It took a month to go, and almost two months to come back.

Through the observation of ocean currents, it is also found that there is indeed a very regular flow of water in this ocean.

In order to figure out the width of this current, the fleet also boldly conducted an experiment on the return trip.

On the road......

Naturally, I saw a lot of sharks and whales.

By June.

The fleet returned to the port of the Wa Kingdom.

The current excavation of gold and silver in the Wa Kingdom has slowly entered a very mature stage.

The annual output of gold and silver adds up to more than 50,000 catties, and there is no problem at all.

And......

In the future, this production should be more and more.

Seeing that the first experiment at sea seemed to be okay, Li Zhi also continued to spend a lot of money to buy bigger and better ships from Yangzhou again.

Estimate......

By then, we will probably be able to build forty or fifty of those large ships.

Subsequently......

Li Zhi also showed Li Zhong all the relevant data obtained from the first experiment.

Don't even say how far this is from the eastern part of Japan to the western part of the Americas, this Li Chong really doesn't know very well.

But......

According to the three years it took Magellan to circumnavigate the world, this year is more than enough.

Of course!

This also depends on the speed of the ship.

At least, Li Zhong feels that with the current shipbuilding technology, it should be a little unsightly.

He had only one advice to the shipyard, and that was to get as many sails as possible.

It is necessary to make full use of the wind power.

"After going out for a month, I can't see anything on the sea, and I can only see a few big fish that spray water on their heads."

"In other words, it won't be a month long."

"Then next time, I'm going to try to go out for two months."

Li Zhong drew a rough map and tried to divide the world into twenty-four time zones.

Youzhou belongs to the East Eighth District, and this Li Chong must remember it.

As for the West Eighth District, what is it......

To be honest, I really don't remember this Li Chong.

No way......

It can only be that Li Zhi and them come little by little.

When it went out along the current, to be honest, it was quite smooth along the way.

It's just that when you have to come back against the current, it feels a little hard.

It would be nice if the steamship could be studied.

Merely......

There was no coal to be found on the road, so it didn't seem to be of much use.

This year......

For the research of aircraft, it seems that it is a bit of a bottleneck.

No way.

The main thing is that this EDM ignition device is too difficult.

Liaodong also wrote a lot of letters to Li, hoping to solve this ignition problem.

But the question is......

This Li Chong really won't.

However, Li Zhong knows that this should be achieved using the principle related to electromagnetism.

For example, high-voltage electricity can be discharged in the air.

But......

How did this high-voltage electricity come from, this question ......

In the past, I had seen a lot of high-voltage power lines on the side of the road, but the problem was, how to make the voltage high......

All I can say is......

He really gave all the knowledge he had learned back to the teacher.

Of course!

As long as you have the formula in your hand, it is not difficult to push back.

It's just that......

Li Chong was a little too lazy to do that.

It wasn't until there was really no way out on the Liaodong side that Li Chong had to put this on his plan.

And......

It's not just about increasing the voltage, it's about making it possible to discharge it consistently and regularly, which is actually the key.

Through formulas, there is also the principle of groping for power generation.

Li Zhong quickly solved the problem of how to increase the voltage.

As for the rest......

How to control, cough!

This one seems to be a little harder.

Li Chong could only let them continue their research.

For electricity, to be honest, it's really a bit difficult.

After all, even if Li Chong is well-informed, often, there are not too many things about electricity on the Internet.

And......

This has to do with electricity, which is obviously much more complicated than steam.

For example, this impulse voltage or something.

But......

It is quite remarkable to be able to propose a high-voltage discharge method to ignite the cylinder of the engine.

Li Chong actually thought about using a lighter, it seems to be called piezoelectric ceramics, but to be honest, he doesn't know where to find it.
