"Yaoyao, just now, did I see things?"

"No, cousin, I don't think this person is a good person. He's lying to Xiaoxue!"

"Don't make a fuss yet, don't alert them."

"Huh? Cousin, you mean?"

"Well, let's pretend we didn't see anything. There are people in the fields all around. If we make a fuss, it won't be good for Xiaoxue's reputation."

"My sister is so smart. I was so angry that I almost forgot about this."

"Concern leads to confusion. Let's go meet up with Xiaoxue and keep an eye on this person to prevent him from getting close to her."

Okay~

After the two sisters finished whispering to each other, they pretended not to have seen anything, went to the edge of the field, and shouted loudly.

——

"Xiaoxue, I brought my cousin to help!"

"Yaoyao? This field is all dirty, why did you bring your cousin here?"

Xiaoxue hurriedly filled the water bag and handed it to Xu Jinbao, completely unaware that his face had turned slightly paler.

...

Seven days a week, five days of school, and two days off.

Today is Friday, and what excites students is not only the holiday after school, but also science class!

I benefited immensely from Principal Jiang's personal instruction!

Regardless of their family status or wealth, all students are treated equally at school, and no one is treated differently because of their family background.

At first, some local gentry and wealthy people thought that it was just a small village school, only to let their sons, daughters and grandchildren become familiar with Magistrate Jiang.

Oh no, now she should be called Lady Jun!

But after a month of school, the visible changes in the children surprised and delighted them.

My son, who used to be naughty and unruly, has now become very polite.

The once spoiled and willful daughter has now become gentle.

My grandson, who used to be selfish, has now become quite generous. Although he asked the cook to make more snacks to take to school and share with his classmates, it's great that he has this kind of awareness!

There were also a few families with good conditions who originally just sent their children to school, but unexpectedly, their summer homework won an award from the school, and they received a bonus and prizes!

Are they short of money?

Not bad at all!

Is it a name difference?

Difference!

The children came home proudly and said that the principal said that after they graduate, those with excellent academic performance will be recommended for jobs!

Although we don't know what kind of job it is yet, it's obviously about sucking up to powerful people!

Wujiacun School is becoming increasingly famous.

Unfortunately, they only admit 300 students each year, and they have to go through multiple rounds of selection.

Trying to squeeze people in?

No way.

Who dares to challenge Principal Jiang?

She was personally appointed by the Emperor—

Lady Jun!

A widow's life takes a dramatic turn for the better!

Three years ago, she was granted the title of County Lady, a seventh-rank official.

Three years later, she was granted the title of Lady of the County, with an official rank of sixth grade!

That speed is incredible!

No one can overlook the fact that this lady of the county also has a son who has entered the Hanlin Academy!

His son is destined for great things!

At that time, above the Lady of the County, there will be...

Jiang Yue was unaware of how outsiders viewed her; if she had known, she would have simply laughed it off.

Instead of indulging in daydreams, why not eat and drink well and focus on how to live your life right now?

"stand up--"

Hello, teacher!

Hello everyone!

"Sit down~"

"In this lesson, we'll learn about buoyancy..."

Jiang Yue looked at the huge crowd of students on the playground and almost had a fit of trypophobia.

It seems we need to get school uniforms in place next year, otherwise, it'll be a huge mess, and all sorts of colorful things...

Science has no lesson plans or fixed teaching points.

Considering that the classrooms could not accommodate all the students, the students had to move their benches to an open space in the center of the school.

Let's call it the playground for now.

Let's wait until winter break when the school is empty before starting the repairs.

What is buoyancy?

The upward force exerted on an object in a fluid is equal to the weight of the fluid displaced by the object.

Jiang Yue cleared her throat, answered the questions first, and then began her demonstration.

"Clap clap clap~"

After the clapping, other teachers helped carry over several prepared basins of water, each with a stone inside.

"Students, remember, the surface of the water is always flat."

If we remove the stones from the water and replace them with water, while keeping the water level constant, what should the volume of the newly added water be?

With the principal's approval, ten students formed a team and began to look at the basin of water placed in front of them.

Everyone saw the stones in the basin, and observant people even noticed the markings.

However, the group still only had a vague understanding of the principal's question. They didn't know what volume was, and even if they did know what volume was, they couldn't convert it.

After much thought, the concept remained vague.

But they knew that the principal was teaching a very powerful kind of knowledge!

It's not just the students who think this way; interested teachers are also racking their brains over it.

After all the students, including Jiang Yue, had examined the basin, they answered aloud:

"Clearly, there are only three options:"

The first choice is to choose an object with a volume greater than that of the object in water.

The second option is to choose an object smaller than its volume in water.

The third option is equal to the volume of the object in water.

Now, which choice do you think is the right one?

This is a very simple question, but it is somewhat unfamiliar to teachers and students who have not been exposed to science for long.

Most teachers and students chose the first and second options, while some chose the third option.

Jiang Yue remembers that the students who chose the third option were all those who had completed their summer homework exceptionally well.

She secretly noted down these promising students, who might become her capable students and helpers in the future!

"The answer is the third option: the buoyant force on the new water is equal to the weight of the new water. This buoyant force is also the buoyant force on the original object. Therefore, the buoyant force is equal to the weight of the displaced water."

After the answer was announced, the teachers and students were in an uproar.

A small number of people applauded and cheered.

You got it right!

For the next two hours, the teacher and students asked questions and answered each other's questions, with Jiang Yue occasionally adding information and clarifying doubts.

She was actually only half-baked; she had forgotten most of the physics knowledge she had learned before.

But ever since Little Ginseng King entered the system space, she has become a "rich person".

I had so many points that I couldn't spend them all, so I redeemed them for math, physics, and chemistry books from junior high to university.

She can't explain the profound concepts now, but she reviews the basics and then rephrases them before imparting them.

As the saying goes, if you master math, physics, and chemistry, you can go anywhere in the world without fear!

The principles of mechanics and buoyancy are applicable to various industries.

There may not be many results in the short term, but given time, a single spark can start a prairie fire!

She did more than just spread the fire; she also left a glimmer of hope for the lives of her entire family!

When the crown prince ascends the throne, will the crown prince's concubine, who is the female lead in the original book, be willing to be subordinate to others?

Once Qingyun and Changjun entered the Hanlin Academy, could they really rest easy and grow into towering giants?

Feeling a vague unease, she wanted to keep some trump cards up her sleeve while the emperor was still alive!
