I saw Li Chong pause and said:

"Of course! If you only think about being an official and plan to embark on a career and participate in politics, then I will not stop you. ”

"After all...... I also know a little bit about the situation in the house. ”

"Your great-ancestor is Zhang Gongjin, the founder of the Tang Dynasty, and Aya once served as the county commander of Wugong County, but unfortunately he is also a jealous talent."

"But...... Datang really needs a smart person like you to lead the development of a discipline. ”

"And I think you're a good fit!"

Li Chong was talking to himself, so that the two people in front of him could only listen.

Then Li Zhong said again:

"How to say it, it doesn't mean that if you do this, you can't be an official."

"In fact, you can also do research while taking the imperial examination."

"It's just a hobby, as long as it doesn't affect you to take the imperial examination."

When Li Chong paused again, Zhang Sui finally found an opportunity to speak.

I saw him kneeling and asking Li Chongdao, "May I ask, what do you mean by what you just said?" ”

Li Chong also said: "What do you not understand? ”

Zhang Sui said: "You just said that Datang really needs a smart person like me to lead the development of a discipline. ”

Li Chong sighed, and then said, "You don't have to worry about this, of course I will also participate in it, but ...... I am old, and learning is never-ending, and I don't want such a knowledge to be passed on, so I need to find someone to pass it on, and even carry it forward. ”

At this time, the woman on the side also said, "But can Sui'er be competent?" ”

Li Zhong wants to take her son as a disciple, no problem.

The question is......

Li Chong said that he would let his son lead a discipline in the future.

That's an exaggeration!

Hearing this, her little heart was pounding with excitement.

Li Chong said: "Madame doesn't need to be presumptuous, in my opinion, Ling Lang is smart enough, I believe that it should not be difficult to learn this." ”

The woman looked at her son, and it was rare for others to think so highly of you, and she immediately said, "Sui'er, don't you see your teacher soon." ”

Zhang Sui was about to salute......

Li Chong stopped in time: "It's serious, in fact, I didn't think about accepting apprentices. And...... I'm just going to give him some guidance in the early stage, a little bit, and then ...... How he was made. Let's be honest...... It's up to him. ”

After that, Li Chong looked at Zhang Sui and said, "Are you willing to study and lead this science?" ”

It's a rare opportunity!

Zhang Sui said to himself: "The kid is willing." ”

Li Chong: "That's okay! That leads ...... Let's start tomorrow. ”

Zhang Sui also said: "Can you start today?" ”

Li Zhong smiled, "It's okay!" Anyway...... I don't have much to do. Merely...... It's not intuitive enough to just say that. ”

Zhang Sui: "? ”

Woman: "? ”

Li Chong said to the servant waiting outside the door: "Fengduo, you go to the laboratory outside the city and help me bring all the equipment for the experiment." It's the box in the corner of the east wall that you can see at a glance. Be careful not to break the contents when carrying them. ”

And the servant named Fontale took the command and departed.

It must have been almost an hour before the thing was retrieved.

And then next......

Li Zhong began to explain various experiments to him.

Include......

Electrolysis of water can decompose hydrogen and oxygen.

For example, the use of toner and the application of high temperatures can reduce the iron produced.

Li Zhong showed the two of them one by one, what these things were at first, and then, after processing, what they became.

Li Chong didn't say it, that is, hydrogen and oxygen.

Instead, a lake-containing expression is used, that is, two different gases are produced, but what are the two gases.

All I can say is......

I don't know.

But!

The properties of these gases can be detected by various means.

Li Chong even showed the two of them the gas exhaled by people, and there must be some special connection between hydrogen and oxygen.

In a word......

It's just a lot of fun.

And its law is so clearly there.

It's as if waiting for someone to unravel it.

Li Chong said: "This is actually a bit similar to alchemy, but, unlike alchemy, we don't seek immortality, we just want to understand the relationship between these things, and whether we can make something new and useful to Datang." It's like saying that the ancients accidentally discovered the secret of copper and iron smelting. ”

"It seems to be playing, and it's not difficult, just do it casually."

"However, what Zhang Sui has to do next is not just to play, or just do it casually."

"I want you to dig out the connections of everything in this world."

"Under what circumstances does one thing become two other things, and what are the two things that are of use to other things?"

"For example, one of the two gases just now, one of which obviously has the same properties as toner, can refine iron."

And ...... I just showed you that on the wall of the test tube, there are even small water droplets, but in the toner experiment, there were no small water droplets in the test tube. ”

"Then can we think that the water that was originally separated by my electricity has changed back into water after some experiments?"

"So what does water have to do with the powder of those ores?"

"Could it be...... Is there any water in the powder of this ore? ”

Zhang Sui interjected: "What is the relationship? ”

Li Chong also smiled slightly, and then said: "I can only say, I don't know, you are smarter than me, I believe, you can understand." ”

Zhang Sui did not doubt Li Chong's words.

Even when he bit his fingers and pondered.

After listening to Li Chong's lecture, when the woman looked at Li Chong, her face couldn't help but look serious and solemn.

In fact......

The women of Datang are not stupid.

Or rather......

In fact, in every era, there is no shortage of smart women.

The woman was also a wise woman.

All I can say is......

Through Li Chong's simple description, the woman understands the gold content of Li Chong, the emperor.

This person teaches people, does not blindly make people memorize, but mainly inspires.

It's a pity!

After all......

If you can let the other party be a teacher, even in the officialdom, it won't be of much help, but it will also have a lot of benefits for inspiring your son to learn.

And Zhang Sui ......

At this time, I was already immersed in this research.

Why can it go from liquid to gas and then from gas to liquid, and what is the connection?

"Where did this electricity come from?"

Then Zhang Sui asked Li Chongdao.
