Luoyang.

Li Chongzheng is seriously doing experiments, such as the materials of phosphorus vapor and boron vapor, which are really difficult to find.

He can only use related phosphorus compounds, as well as boron compounds, of course, this boron Li Zhong doesn't know if it's the boron.

Anyway......

In medical books, this boron, which is written as 'borax', has the effect of clearing heat and eliminating phlegm, detoxification and antiseptic. Li Chong felt that even if it was not elemental boron, it must be a substance containing boron, so it should be the same when used for it.

Put it in an airtight glass container, heat it, and tell the truth......

Li Chong also didn't know how long it would take to heat up.

It could be an hour, or it could be ten hours.

In a word......

Let's try them all.

After all......

What if the blind cat runs into a dead mouse?

Li Zhong knows that many new discoveries and inventions in the world have come from this way.

Of course!

Before that, you have to be like him, have a certain amount of knowledge, or theoretical direction, so that you can do more with less, rather than relying on luck completely.

After Li Chong's efforts.

All I can say is......

This smoked seems to be a little different from the beginning.

Merely......

This difference doesn't seem to be obvious.

Other than that......

Li Zhong felt that it seemed a bit dangerous to do this experiment.

Because......

He seemed to be able to smell the poisonous gas.

Although he didn't know if it was poisonous gas, his intuition told him that this unpleasant smell must be harmful to the human body, and every time he did an experiment in the future, even if he didn't wear a gas mask, he should at least wear a wet towel.

Otherwise......

When the time comes, if you get a cancer, it won't be good.

Although......

He didn't seem to be so afraid of death.

But he can't poison himself to death, and if he poisons himself, what will the people of the future think of him?

Not......

Cough! Maybe it's even more dramatic?

Saying......

Historically, have there been any scientists who have been poisoned for doing experiments?

Come out after doing the experiment.

Today's experiment failed again.

But......

That's what scientific research is all about.

Only by constantly trying, persevering, and overcoming difficulties can we achieve success.

When you come out, take a warm bath.

Afterwards......

Under the service of a slave maid, he dried his hair and put it on a shelf to dry, and Li Chong read the letter sent back from the prince of Liaodong Liao by the light of the electric lamp.

"This is a typical time to make cakes, there are fewer suspects, and when the cake is divided, there are more suspects."

Just briefly glanced at a few columns of words on the other party's letter, Li Chong said.

But one thing to say, when he thinks about it, is indeed a problem.

All I can say is......

In times of peace, the population will grow exponentially, although it has only been less than 50 years since the Liao State, but it is predictable that in the future, this population will only increase, and when the time comes......

Whether this piece of land in Liaodong alone can support so many people is a question.

It's like the rabbit in Australia, the growth rate.

And......

In recent years, there seems to be a situation that is.

Because the Liao State has never collected taxes on the Han people, but on the remnants of Goguryeo, Baekje, and Silla, it is taxed.

Those remnants of Goguryeo, Baekje, and Silla, right?

They all asked the Han people to intermarry, or they were willing to be concubines for the Han people, at least they could have food and clothing or something.

After these people became concubines for the Han people, according to the past practice, they were regarded as Han people, that is, they were also distributed with grain, so this ......

In the long run, the number of these Han people will also increase, and the growth rate will be faster.

I don't know when Liaodong began to consciously develop into the Northeast Plain, probably for this reason.

Thinking of this, Li Chong also had to nod his head, and said to himself: "This prince of Liao, I didn't expect to be able to pay attention to such a problem." ”

But think about it!

After all......

This flesh was cut from him, so of course he understood it very deeply.

Then ask yourself what you think about it.

"Forehead ......"

Li Chong could only say that he was lying down and watching.

There really doesn't seem to be a good way to do this.

No wonder Li Zhi used to be so concerned about his fertilizer.

This contradiction that grain production cannot keep up with population growth is indeed a very thorny contradiction.

Key words......

If the Liao State says in advance now, I won't support you, or if you have to pay some labor to get food, and if you don't pay for labor, there will be no food, then it will definitely cause the people's hearts to turn back.

To Li Chong's surprise, the prince of Liao was able to see so long-term.

I thought about the future.

In Li Chong's view, the Northeast Plain is so big, it will take at least a hundred years before it is estimated that all kinds of problems will break out in Liaodong due to food shortages.

Come to think of this......

Li Chong beckoned to a waiting slave and asked him to bring a brush.

Directly wrote four words, "Immigration to the Americas!" ”

Yes!

That's all he can do.

If there is not enough food in the Liaodong Plain and the Northeast Plain, then the only way to reclaim new land will be to reclaim it.

This can at least allow the Liao State to live for another one or two hundred years, or even three or five hundred years, it shouldn't be a problem, right?

After all......

It's so big over there!

Of course!

The Americas also have its disadvantages, for example, it is prone to hurricane disasters.

Speaking of which......

If you feel that the Americas are too far away, then immigrating to Wajima is the same.

It's just that......

In the case of Wajima, it is not suitable for growing wheat, but it is more suitable for growing rice.

But......

It's just like we're stalling for time.

In fact, he did not give a solution that could completely cure the root cause.

Lee scratched his head.

Hand back the pen and paper to the slave who was waiting.

Forget it!

Don't think about it so much.

And......

To be able to explode troops and occupy the Americas, to be honest, it is not a bad thing.

As long as you can explain to the people that the imperial court is also in difficulty now, do you have to be in the same boat now?

And then let the people from each household send one or two people to develop the new world, which is not impossible.

Come to think of it, if you really say it so clearly, the people will definitely not be unreasonable anymore.

Merely......

If you really go to the Americas, so far away...... If you don't listen to the orders of Liaodong in the future, you can only say it, and it's not easy to say.

The contradiction between population and food can be solved, but if it is controlled......

That's why he developed the radio.
