The battles in the court were not affected at this time by Li Zong in Jiangdu.

Three months passed without realizing it, which made Li Zong couldn't help but remember that just a few days after he got married, he plunged directly on Ying'er's thigh and went to sleep in his brother's pear garden.

So when Li Zong looked at these pear woods that had just been dried, he couldn't help but sigh.

When Ying'er saw this, she couldn't help but say, "Husband, why do you sigh at the limu? These limus are not broken either."

Li Zong said: "I am thinking about it because I am not aware of it. It has been three months since I knew it."

"It's been so long since I last listened to the sound of the piano while I was pillowing Ying'er's thighs."

Ying'er quickly stopped him:

"Husband, stop talking."

If he asked him to continue talking, he would probably tease her again.

But thinking about it carefully, it seems that it has been quite a long time.

"If you like to listen to me, I will play it for you another day... Ying'er will play it for you."

"Okay! I think about it, where to go to play this time. Why not let's go rafting, this artistic conception is better!"

"Husband, you'd better do the serious business first."

The two of them came to the place where the pear wood was stored. After soaking in water for one month, the pear wood was dry for two months and it was no longer so easy to crack.

Now, all the two of them have to do is take out all the pear woods and make them into carved plates.

After a busy morning, Ying'er also came up to wipe Li Zong's sweat during the break.

Maybe it's summer, and the weather is getting hotter now.

However, Ying'er is most concerned about his physical problems.

I am really afraid that he suddenly fainted on the ground at some point.

"Husband, do you feel uncomfortable now?"

Li Zong understood what she was asking.

In short, it should be difficult for him to get over this hurdle of serious illness in a short period of time.

So I had to say, "Besides feeling a little hot."

"That Ying'er will slap you."

Li Zong felt that he was not slapping or fanning, so he also asked, "Where is the fan?"

"?"

Ying'er was holding a small fan, obviously not understanding it.

But that's true. During this period, he has not unlocked a new position with Ying'er, so of course she doesn't know where to slap it.

Ying'er didn't answer his joke, so he had to say, "Forget it, I'm almost finished."

A few days ago, Yang Jiayan had someone bring him back to him.

Although he has never seen what graphite looks like.

but……

I think this should be graphite.

The weight is about two pounds, so you should be able to make a lot of pencils.

only……

He thought about it again these two days and felt that the practicality of the pencil was not very good.

Mainly, he went out in the past two days and suddenly was inspired to see how carpenters of this era draw lines.

In fact, using a brush, you can still draw straight and slender straight lines.

All you need is a ruler and a small stick stuck on the brush.

Use the small stick to control the tip of the brush that only touches the paper, and then draw the small stick against the ruler.

The lines drawn in this way will be straight and will not stain the ink on the ruler.

I have to sigh at the wisdom of ancient craftsmen.

...

"alright!"

"Let Xiaoqing ask Fazhang to come and send the things to carve."

Then Ying'er went to find Xiaoqing.

Xiaoqing asked Fazhang to come again.

All the finished carvings were sent out.

Next, I will wait until the engraving is completed, and I guess it will take a lot of time.

He and his father agreed to produce results within half a year, and there are still three months left, and it is still time.

After finishing his work, he washed his hands, then hugged Ying'er and took her hands to play with her.

Holidays today.

The students all went back, but Li Zong left them homework.

That is, let them investigate how many chickens, ducks each household raises, and how many people each household has.

Why ask this?

This can somewhat reflect the living standards of the people in a place.

It was as if Sima Yi heard that Zhuge Kongming only ate three or four liters of rice for each meal, and Sima Yi concluded that Zhuge Villager would not live long.

This is the power of mathematics!

At that time, when they collect the data back, Li Zong will let them understand from this special perspective that mathematics is not really useless.

Mathematics often allows us to discover rules.

even……

Master the economic development of a certain area and a certain area.

It’s a businessman!

You must be sensitive to the economic sense. When you know that there are many chickens and ducks in this place and few chickens and ducks in another place, can you buy them at a low price and sell them at a high price?

Then calculate the cost. If you can still make a profit after removing the cost, then the business can be done.

What mathematics plays in this process is a process of measuring gains and losses.

certainly!

In fact, Li Zong does not recommend doing this.

Hello everyone, our public account will find cash and red envelopes every day. You can get it by following it. The last benefit at the end of the year, please seize the opportunity. Official account [Book Friends Camp]

Because this is equivalent to speculation and does not help the overall productivity improvement.

The biggest problem with the area where he lives now is that the population is small.

Moreover, production technology is relatively backward.

There are few irrigation facilities, and a large number of places have not been cultivated.

Is there any way to change this situation?

Of course there is!

only……

He is not the kind of person who is good at mechanical making.

And if you want to do it, you must do it for yourself first. Although the Li family seems to have so many people in the county town, it also has its own manor outside the city.

The servants don’t say they are a military force, but at least one or two hundred people are brought out, it should be no problem.

In fact, these are the confidence of the aristocratic families.

Especially for the Jiangnan family, this can even be used to despise the court.

No matter in the past or now, the differences between the north and the south, or differences, have always been there.

Northerners look down on southerners because you are a remote place.

The southerners look down on the northerners because you are not as many as my manors, and your land is not enough.

In name, the whole country is unified.

The problem is that both parties just make do with each other for their own interests.

Therefore, the average Jiangnan family is not willing to be an official in the capital.

When you come to my Jiangnan land, you have to look at the face of my Jiangnan family.

...

Li Zong hugged Ying'er, played with her little hands, and suddenly said:

"Or what if we go and see our place tomorrow?"

After hearing this, Ying'er asked, "What's so good about this?"
