The end of the Upper Metaverse.

Everyone was talking about what the hell that firework was.

Li Chong also published an article in the Science Newspaper titled: "The Flame Color Reaction of Metal".

That said, yesterday's fireworks produced so many different colors.

That's because there are a variety of different metals burning inside.

As soon as this article was published, it immediately attracted the attention of the Datang alchemy community.

For this reason, there are many people who want to come to ask for advice.

Li Chong simply gave a lecture in Luoyang's Guozijian.

The theme of the lecture is that in the future, we should all systematically understand the world.

Just like when Shennong tasted a hundred herbs, he carefully analyzed the characteristics of everything in this world.

Of course!

In fact, the ancients already had such a consciousness.

It's just that......

The practice of the ancients was still not systematic enough.

And......

Their accounts are too lake-contained, too mysterious.

It's like Chinese medicine.

Of course, Li Zhong is not saying that Chinese medicine is bad, it is like observing the problem from a macro perspective, and observing the problem from a micro perspective.

Macroscopic, they have seen a lot, and now, they want to strengthen their observation of the microscopic.

And then...... From a scientific point of view, to re-understand the world.

Other than that......

Li Zhong felt that another book should be compiled, similar to the kind of encyclopedia.

All the substances that exist in this world must be recorded in their characteristics.

Not......

And then...... Li Chong issued a merit order, if you are interested in this work, you can come to him.

Of course!

If you want to pass this, as a springboard, then you want to rely on your relationship with him to become an official in the court or something.

Then don't come, because ......

It's just a very ordinary, ordinary job.

And......

Only for those who are really interested in this aspect.

As for the treatment......

Li Zhong can guarantee that it will definitely not be too bad.

The reason why the United States is so strong and why science and technology are so advanced is because they are willing to spend money on this.

Li Chong can only say that he is relatively rich.

Engaging in scientific research like this, I don't think it's a big problem.

After the lecture ended, half a month later, Li Chong met five or six people who came to him one after another to sign up.

After all......

These students studying in Guozijian are not all materials that can become officials.

Even......

Yes, he may not have much interest in being an official.

Li Chong specially bought another house, and then changed it into a research room.

This is the first thing to be done.

It is to let them study the properties of this urine first.

For example, what is the boiling point and what taste.

With something, what effect will it have.

It can only be said that everyone is confused, because ......

Shouldn't it be for them to taste it for themselves?

Don't even say it!

Li Chong really tasted it!

It's not five Japanese girls.

It's Li Li's.

Because Li Lizhi has a lot in this regard.

It's all for science!

Sometimes, a sacrifice is needed.

But don't be a pervert.

If you feel that other people's urine is not good for your mouth, then you can taste your own, or taste the person you like.

Of course!

These are the most basic things to get started.

Li Zhong actually wanted them to discover phosphorus.

And why plants can grow well when they water their urine, it's because of the phosphorus in them.

Of course, Li Chong can directly give them an answer.

It's just that......

In this way, there is no point, what he wants to cultivate is actually their spirit of scientific exploration.

At Li Chong's request, they all went back one after another to try it.

Some may be sick, and then the urine will appear different.

Then this thing can also be discussed with each other, maybe, that special one, maybe the body is sick.

Every once in a while, Li asked them to work on a topic.

Now that all kinds of experimental equipment have been developed, there are more and more things that can be done.

As for the treatment given to these people.

Let's start with the nine officials of the Tang Dynasty.

Wait for when they have made meritorious contributions, or as the number of years of work increases, they will increase little by little.

It didn't take long......

They got a lot of information about the urine.

So much so that in the end, even they couldn't help but be a little surprised, they didn't expect that this seemingly simple and ordinary thing contained so much knowledge.

Even......

In the end, by boiling urine, they also boiled something magical that would glow.

You see!

These are not all gains!

Of course!

This process is also really full of flavor.

Why is urine filled with a pungent smell and what exactly is this smell?

Why does boiling water in urine leave something that glows?

Why does urine have a growth-promoting effect on plants?

Is there a secret they don't know?

These things are worth pondering.

Then wait for the article to be published in the Science Newspaper.

Cough!

It can only be said that the nobles of the Tang family who read the newspaper are really a little surprised that these people have nothing to do.

Hello, don't study other things, what do you study urine?

It's no wonder that in recent months, it seems that someone has been buying urine from outside.

They thought it was a little strange at the time!

Li Chong's side......

With these people here, and taught them how to conduct scientific analysis and research, then Li Chong will be much more relaxed.

After studying the urine, in order to provide the possibility for the next step of mass production of chemical fertilizers, Li Chong also began to ask them to study the water of Qinghai Lake.

As we all know, the lake water must contain a lot of magnesium, potassium and other metals, if potassium ions can be extracted, then mass production of potassium fertilizer will become possible.

Other than that......

In terms of this stone mine, it is also necessary to conduct research, but generally most of the useful stone mines are hidden hundreds of meters or even thousands of meters underground, which is really difficult to get to the truth.

Anyway, if there is anything that has come out in the open air and looks a little special on the outside, they will all be collected first and let them study it.

With these helpers, Li Chong can have a lot of time to listen to music.

At the beginning of the year.

Liaodong also made the third voyage.

On the third voyage, Li Zhi was no longer satisfied with the first two petty fights, but let the fleet bring enough food for a year, which is obvious.

If you don't find the New World, you don't have to come back.

On board, all the crew members were both entangled and afraid.

Because Your Majesty said that if you go there, if you really find the gold, then all the gold you bring back will belong to them.

Other than that......

Your Majesty will give them other rewards.

As the saying goes, people die for money, birds die for food, however, they have experienced the last catastrophe.

What will happen on this sea, no one knows.

And the breadth of the sea has no bounds, it really makes people feel very oppressive, and every time they go to sea, they are actually afraid.

But......

It seems that they have no other choice.

I had to bite the bullet.
