Unlike other disciplines, there are no shortcuts in chemistry.

This winter.

The carriages and horses are sparkling.

Zhang Sui and his mother were taken to Luoyang by Li Chong.

And then......

In another suburb of Luoyang, Li Chong also prepared a laboratory for the other party.

Don't care what Li Chong asks him to do for now.

Just being able to receive Li Chong's letter was enough to cheer him up, and Li Chong also said in the letter that there was one thing that he needed his help with.

Li Chong felt that he might be able to help.

His mother also knows what kind of person Li Chong is.

Not......

Except for being said to be a little, in other aspects, it's pretty good.

In terms of identity and status, the other party is the emperor.

In terms of learning, the entire Academy of Sciences is his disciple.

You said that if she can be appreciated by such a big person, then she is naturally happy.

It's not ......

After thinking about it for a while, I felt that I couldn't let go of such an opportunity.

Even if you smash the pot and sell iron, you have to go to Luoyang.

Whether the glory of the ancestors can be reproduced depends on his son Zhang Sui.

Zhang Sui also felt that this was a very good opportunity to learn from Li Chong's side, although the specific content of what the other party asked him to study was not clear in the letter, but ......

The other party will not lie to himself.

Especially in the letter, it is clear that he is a big man of the other party's status, but he almost asks for his help in the tone of his peers.

It really made him a little confused about what to say.

"It's here!"

The servant led the way.

The first thing I went to was the residence of the two in Luoyang City.

This house can't be said to be very big, but it is also ten acres, if it is according to the current housing prices of houses in Luoyang City, this ten acres of land alone should cost almost 500,000 yuan. And it's just a few.

And it is such a house, but the servant was on the spot, so he said to the two, "Madame and Xiao Langjun will come down to rest first, go in and have a cup of tea, and if we will later, we will go to the government office to transfer the house, and after that, this house will be given to the two residences." ”

This frightened the woman, and she hurriedly said: "There is no merit, and we can't live in such a big house." ”

The servant said, "This is the intention of our master, and the villain only does what his master wants." If you have any grievances about this, you can say it, and I will convey it to my master. ”

"......" woman.

Knowing that the other party was a servant, the woman didn't bother anymore.

After all......

The other party really can't speak, so he can only see if he can go directly to meet the other party's master, and then let the other party's master take it back.

Then he said: "Is your master free today?" ”

The servant said, "My master may not be free for a while in the next period of time, because he has returned to Chang'an." ”

"......" mother and son.

Servant: "It's a bit of a matter to go back to Chang'an, but it should be ten days and eight days, and I think I can come back." ”

"Oh well. It's just that...... We really can't want this house, so let's put this transfer aside for the time being. ”

Seeing the other party's embarrassed look, the servant also said, "Okay, let's wait for my master to come back." Now, you will live here first, and you can tell me what is missing in it. Let's go in first......"

After going in.

This house can really be called a mansion.

After all, Bai Juyi's house is only so big.

Of course!

Bai Juyi's house, that's where he lives is so big.

There are also five acres of yards.

And this one, compared to Bai Juyi's, may be one-third smaller, but to be able to live in such a house in Luoyang City, it can only be said that it may be that some people who are officials may not be able to have such a good treatment.

Even......

There is also a small pond and a small bamboo forest in the house, and there are a few fish in the pond that I don't know what kind of fish they are, which is strange and beautiful.

The woman couldn't believe it, even though she knew that her son was a little smart, but she didn't want to accept it.

Is it because the uncle's daughter married into the other party's family, so that's why it's like this?

If you think about it......

It's not impossible.

Merely......

This house is still too big.

And it's a gift......

Zhang Sui also looked east and west, not to say that he had not seen the world, he had still seen the world, but he was ......

After all, this is something that someone wants to give him.

Then he was even more curious about what the other party was going to do next.

Li Chong's side......

This year, he also went to see Li Chunfeng on purpose.

After all......

There's a successor!

Rest in peace, friend.

After paying homage to Li Chunfeng, Li Chong returned to Luoyang.

After returning to Luoyang.

I also learned about the situation over there.

All I can say is......

This is also normal!

If you are more cautious, maybe you have already begun to suspect that he has bad intentions, and maybe you want the other party to do something bad to kill your head.

Li Chong went to meet the other party in person.

Subsequently......

A pleasant greeting.

I didn't say a word about the house.

Because it's not necessary.

Anyway......

If the other party feels uneasy, let's stay first.

I asked if there was anything else I needed.

Afterwards......

In front of the other party's mother, Li Chong had a rough talk with him about what he was going to do next.

Li Zhong directly gave an example, many things in this world can actually be transformed into each other.

For example, when you make iron, you need charcoal, which is charcoal, which allows iron to be refined from iron ore.

For example, we people always have to breathe every day, we inhale, and then, what is the difference between the air in the mouth and the air exhaled?

What kind of changes have gone through in the human body.

That's what they need to accomplish.

to discover and grasp the pattern of this change.

Li Chong said that this is also the case: "You must not underestimate this little thing, as if this is not a big knowledge. ”

"In fact...... This is so great that even I can't say I can master it. And...... This knowledge can help us discover new things. ”

"Think about when our ancestors didn't discover bronze, think about when our ancestors didn't discover iron, then they had to use stone tools polished from stone for hunting and farming."

"And since there was copper, and since there was iron, you can look at the hunting tools and the farming tools today."

"It can be said that if it weren't for the discovery of copper and iron, there would be no Datang like us today."

"Soldiers can wear thick armor to protect themselves, and people can use iron farming tools, and farming can be twice as effective with half the effort."

"I believe that substances like copper and iron must still exist, but they have not yet been discovered."

"And what you have to do is find out what you want!"
