The seventeenth year of Yuan Heng, November.

Large bags of salt brine and other minerals were transported to Li Chong's laboratory in the princess's mansion.

Then, in December, Li Chong basically completed the analysis of the ingredients.

By varying the solubility of different minerals at different temperatures, Li Zhong quickly separated relatively pure potassium chloride from these salt-formed minerals.

Why is it relatively pure?

Because if you think about it, you know that there must be magnesium, barium and other metal ions in it.

But no matter what, this potassium chloride can still be made after laboratory purification.

Some of these salts and other minerals are extracted from Qinghai Lake.

Yes, in a place called Zar Khan.

In a word......

Li Chong's mission with the expedition team is to bring him back, whether there are any or not, anyway, it is a mineral.

And this year, Murong Nuo, the king of Qinghai County, was still alive.

All I can say is......

I really didn't expect it.

But......

It's also a shame that the other party is still alive, which is quite helpful to them.

After all......

It's a completely different situation with locals leading the way, and not having locals leading the way.

Li Zhong weighed the purified potassium chloride and found that the content of potassium chloride in the ore formed by these salt brine was quite high.

If you can develop it......

Then Datang's fertilizer production should not be worried.

Of course!

I also learned from the people I sent out that this kind of stone is relatively rare.

However......

Li Zhong thinks that this is not a problem, because since it can produce a piece, that is, by controlling the concentration, controlling the temperature, etc., it will definitely be able to produce more of this ore.

Of course!

Now these purified potassium chloride have been 'safety verified'.

Cough!

Next, we still have to sacrifice five Japanese women.

Li Chong felt ......

If they were all allowed to wear the clothes of the Tang Dynasty, it would seem that they would lose the taste of the Wa Kingdom.

Of course!

If they were to be allowed to wear the clothes of the Japanese country, it would not seem to be very good.

At last......

Li Chong simply designed some according to what he liked.

Then let them put it on.

Even......

I can't rule out what kind of miniskirts, white stockings or something.

For example: sailor suits, ahem!

While studying ore minerals......

After Li Zhi ordered people to complete the transcription of the nautical diary, Li Chong also studied the diary across the Pacific Ocean.

How to say it.

It's better to look at the weather.

The good news, though, is that at least their ships are strong enough to withstand a certain amount of wind and waves.

Li Chong felt ......

When you have rubber, you can make seals, and you have mastered the sealing technology, then the next ......

Liao might be able to directly use steamships to sail across the sea.

Of course!

Before that, the Liao State had to have a colony of its own in Southeast Asia.

After all......

Liaodong definitely can't grow rubber trees.

Other than that......

If you can establish your own colony or base in Southeast Asia, then, when the time comes, it will be much more convenient to come back from the South Pacific and supply on the way.

It can be regarded as a small suggestion to Li Zhi casually.

For example, in the Philippines, that land is very good.

Even......

That can be said to be a 'gateway'.

From his voyage diary, Li Chong also seems to have found evidence that the Indians smoked tobacco.

Merely......

At first glance, the crew did not seem to be very accustomed to this kind of thing for the first time.

But Lee recounted the time, and the fleet had been in the Americas for at least about a year.

Li Zhong did not believe that the crew did not bring back the tobacco on the way back.

So when he tried to flip back.

Really!

Afterwards......

Li Chong saw that they were also obsessed with tobacco smoke.

I can't say I'm obsessed.

But anyway......

The benefits of this thing must be mentioned, for example, to refresh the mind.

Li Zhong saw this.

It can only be said that his brows are slightly furrowed.

Because this thing, in addition to being good for taxes, it seems to be harmful to individuals.

Should this kind of thing be banned?

Li Chong is not easy to say.

It can only be let Li Zhi, and the five small ones, be cautious.

As for the things that the fleet brought back from the Americas, Li Chongdu gave them notes one by one.

Li Zhi got Li Chong's note.

This reflects the importance of Li Chong.

Obviously, Li Chongdu should not have been to the Americas, but he has a lot of treasures about these things.

Let's be honest.

Sometimes, even Li Zhi had to wonder if Li Chong came from that continent after all.

Li Zhi said this to the four of them. Don't say it, the four of them have to be suspicious.

In a word......

They are very mysterious.

Without leaving the house, he can know everything under the sky.

Li Zhi accepted Li Chong's proposal.

Next......

It is also preparing to go south, first go to Southeast Asia to occupy a piece of land.

In fact......

If you can, it would be best to occupy both Southeast Asia and Taiwan.

Of course!

This will inevitably harm the interests of Datang.

This overseas wealth was divided between Li Zhi and Li Xin.

When the time comes, they will come to harvest the leeks of the Tang Dynasty.

Is there anything left of Datang?

All I can say is......

Thinking about it this way, Li Chong also had to have a little worry about the future of Datang.

In fact......

It's not true that Datang can't live without pepper.

It's just that......

In order to pursue a better life, there are some costs that must be paid.

And this price is the outflow of capital overseas.

How can this outflow of capital be controlled?

Li Chong can only say that he is not studying economics, and he really doesn't know much about this aspect.

Anyway......

It is certainly not okay to buy other people's things unilaterally, and you can't sell your own high-value things.

It is best to be able to achieve a relatively balanced import and export balance.

It's just that this kind of statistics may be okay in future generations.

Leave it now......

Estimation is comparatively difficult.

Holding a widow in his arms and playing with him, he played with the other party until he was already weak, in fact......

There is not a day when Li Chong is not concerned about the future of Datang.

When the time comes......

When they went to the Western Regions, what did these feudal countries rely on to eat?

Providing food?

It's a no-brainer, but it's the lowest.

Maybe you can join forces with Li Zhi to engage in tobacco trading together.

But let's be honest......

This business should be cooperated with Li Xin, maybe it will be more convenient.

With a chirp, the widow was then unbearable.

But......

This made Li Zhong pay attention to the ore on the table.

I don't know if it's feasible to develop copper mines in the Western Regions or something?
