The next day, Yan Yu began to give her father special training before the exam.

Still unable to live peacefully at home, on the road, in the village, in the charcoal field, at the repair sites of various broken houses...

The main focus is hard study and training.

First, go through the basic original questions in the arithmetic book, then do it again after making slight changes, and repeat the wrong questions three times... The classic original questions will be silent...

Then there is the recitation that Yan Laoer is familiar with. He strives to be able to pronounce the previous sentence and think of the next sentence, to be able to silently pronounce the previous sentence when there is a second sentence, know the source, and write difficult words well...

Yan Yu is a person who has a horizontal contrast with his own level.

For example, her eldest brother, such as Liang Tongsheng.

Liang Tongsheng is better than her in reading more, whether it is words or articles, writing is definitely better than her, but in terms of in-depth understanding, logical arrangement and keeping the main point of the whole text...I am afraid she is even better.

Yan Xiangheng is a little worse than Liang Tongsheng. This is an advantage due to age, which can only be equalized with time.

This gap will be difficult to make up for at least two to three years.

My uncle once said that my eldest brother is no problem as a scholar. So from comparison, we can see that her level is almost equal to that of a scholar?

Therefore, Yan Yu asked herself whether she could tutor her father, a poor student with pre-exam syndrome.

If he really let him go to Mr. Cheng's place, she would not be at ease.

Every one of the adults I have come into contact with is not simple.

Think about it, they are all elites who fought hard in the imperial examination field with thousands of troops, and they have served as officials for many years. Which one is free?

Mr. Cheng is just a prankster. He likes to spread gossip with his master and is well aware of all the happenings in Yongning City. How can her father keep it a secret?

If you really get in front of Mr. Cheng, you'll see something out of nowhere.

Her godfather had to let them know, and he would not be allowed to talk about it to anyone until he died.

It's not that it's serious if anyone knows about it, but it's her godfather who got the news from the King of England.

What is a confidant?

A confidant is one who can be trusted.

From the perspective of the superior, you can do some things secretly, and he doesn't care.

But if you do things with your mouth, it will not be so reassuring.

Yan Yu also considered whether to send a message to her elder brother.

Then I thought about it, with her elder brother's level... she really didn't need it.

The uncle attaches great importance to teaching them practical matters, so the eldest brother is good at both arts and sciences and is not lame.

"Xiao Er, the method you mentioned really works. Look, this is what we froze yesterday!" Xiao Xiaozi said excitedly.

How could Yan Yu not think of the problem that Yan Laoer thought of about the difficulty of getting ice?

In this season when dripping water turns into ice, what can be done faster than using molds to freeze ice!

As long as they have the corresponding mold and only need two or three hours, they can freeze the shape they want.

Yan Yu and the others used ice cubes from local materials. It took them a lot of work to dig out these two large ice troughs. They put soil and hay clippings in them for insulation. The ice removal went smoothly, except for a few spots.

If there are adhesions, just use a file to repair them.

After the inspection, Yan Yu said: "It seems that the ice mold is not working. The adhesion is too strong. Since we want to save trouble, it is best to pour it in and shape it immediately. I will move the square wooden box from home to try it. If it works, I will

Remember you have some at home too, bring them all."

Square wooden boxes became popular for a while, because the Yan family was using them, and the village followed suit and made some. The shape is simple and the materials are easy to obtain. You can also make them with crude boards made at home. Of course, the effect of filling water is good or bad. Later, everyone

I still feel that the round barrel is useful, and the square box is not used anymore.

I used it for a while while pressing the fodder, and then left it alone.

Look now, huh? It can still be used?

The children did not wait for Yan Yu to finish the experiment, but pulled their own sledges and rushed home.

That's right, the children in Xiao'an Village are so good at traveling.

If there is no dog at home, they are not afraid. They can pull it by themselves and run not much slower than the dog...

Yan Yu was about to calculate the amount of ice when he slapped his forehead.

What a ready-made arithmetic problem!

"Dad! Come and help me with the math!" Yan Yu shouted.

Yan Laoer was sitting in the igloo built by the children on the river, studying questions. Not to mention, this igloo looked cold, but it was really okay to stay there.

Light a fire, and the light from the fire will make the ice cubes glow red, which is beautiful and warm.

"Come on, come on!" Yan Laoer walked out and immediately felt the severe cold outside, shrinking his neck.

"What the hell?"

"Calculate the amount of ice cubes used in this igloo." Yan Yu said.

"It's still a matter of calculation. Just ask a child to count." Yan Laoer said subconsciously.

"Dad! This is a real problem that needs to be solved by arithmetic in life!" Yan Yu said with a sullen face: "If you have to count for everything, what else do people need to study arithmetic? Just count!"

"You're right, I guess!" Yan Laoer didn't argue with his daughter, mainly because he couldn't argue...

Yan Yu was still standing by: "Any solution can be used, easy or difficult, all for solving problems. Except for the a few original questions in the arithmetic examination, which require good steps to be written down, you can do whatever you want.

The key to performance is right or wrong. This is much better than when I took the exam. We were not allowed to make a mistake in any step. If you use an over-the-top solution, you may not be awarded points. It is common to solve a question that fills a paper.

Any larger characters must be written on the back..."

"My dear girl! It takes so much trouble to make your igloo. Even if you use a mold to remove the ice, it's still laborious. In fact, an igloo can be made. Look at the thick snow on the ground. Building an igloo is much faster than building an igloo."

Yan Laoer couldn't help but said.

"Dad, you are too careless to observe. Didn't you realize that there are only a small number of people here? Most of them are building snow bags in the village!" Yan Yu rolled his eyes.

They take their Boy Scouts too seriously.

Her father didn't notice such a big project!

Snow houses are naturally faster and easier to make than igloos.

However, considering its durability and her idea of ​​an ice cover, Yan Yu decided to experiment with the igloo.

In other words, the kids here all belong to the R&D group.

Yan Laoer turned off his microphone.

Go back to the igloo to do the questions.

Not long after, the children came back with the wooden box.

There are quite a few.

It's much easier to freeze ice in a wooden box. Just dig a hole in the river and pour water directly into it.

This chapter is not over yet, please click on the next page to continue reading the exciting content! While scooping water, you can also catch fish, killing two birds with one stone. The children were very happy.

When it was almost noon, Master Lu came over.

"Boy, I've seen the snow bag you piled up. It's not too big. The weather is cold and the snow can hold up. But if the sun comes out, the top will collapse easily. It's best to find something to hold it up from the inside...

"

Master Lu made several suggestions based on his many years of experience in building houses.

Yan Yu couldn't help but nod, and the children gathered in a circle. You and I said something that was either childish or feasible.

Master Lu was too busy, so he left after saying a few words.

When the meal was approaching, everyone was hungry and began to rummage around the stove and pot they had brought. They fetched water from the hole in the ice and boiled it. Then they cleaned up the fish they caught, cut them into pieces of different sizes and threw them into the pot.

The water is boiling and the fish is cooked.

Add a little salt, and the salty smell wafts out. The children's stomachs growl one after another. You look at me and I look at you, laughing so hard.

Let’s not eat the fish for now. Let’s have some fish soup to warm our stomachs.

Add more water and throw in the dried vegetables.

When the dried vegetables slowly unfolded, the fish meat was already stewed and melted into the soup.

The children took out pancakes and skillfully rolled them with a small amount of fish.

Yan Yu neatly rolled one for her father.

Then it's your own.

The hot vegetables and hot soup have softened the dry and hard pancakes just now. Take a bite and follow it with a sip of fresh fish soup. Not to mention how delicious it is!

"Xiaoer! Yan Xiaoer! Is that you!" Someone shouted from the other side of the river.

Yan Yu sounded familiar and looked in that direction.

I saw a carriage parked on the other side of the river, with a little fat man standing on the carriage...
