Great Blue Night Watchman

Several women gathered in Tingyu Pavilion.

Lin Su's song Blue and White Porcelain attracted all the women in the west courtyard. Lu Yi was the most excited. She threw herself into the arms of her husband and wanted to eat him. My husband, you are a bad guy. The song you sang almost gave away my soul. Gou ran away and you didn't reveal it for so long? I seriously doubt that Under the Qingcheng Mountain, Rain and Wind in the West Lake and A Thousand Years of Waiting were all created by you.

As soon as Lu Yi expressed his suspicion, it instantly resonated with the girls.

Yes, The Legend of White Snake is yours, and the four most talented women in the capital are also yours. Can they create a new kind of music behind closed doors for half a year? Unlikely? It must be my husband who has let you off...

I don’t know who said this, but Lin Su thinks it’s quite ambiguous...

Just when he was struggling to explain, Xiao Tao ran over: Master, two women came to visit, saying they are from the Mo Sheng family and the Le Sheng family...

As soon as she ran over, Lu Yi and Cui Ying all sat upright. Xiao Tao had been thinking hard about getting into his bed, and the entire West Courtyard knew about it. The women in the West Courtyard were very kind and did not provoke her on this issue.

Lin Su was slightly stunned.

Sister Chen, Lu Yi, Cui Ying and Qiu Shui Huaping were also stunned.

The thoughts running through my heart are connected with each other...

Everyone knows that the saintly daughter of Mo Shengsheng's family was abducted by him and worked as a teacher at Haining Academy for more than a month.

Does he care about other people's academics or his people? It is also something that everyone has speculated about for a long time but has not reached a conclusion.

Now this chick is here.

In addition, a member of the Lesheng Holy Family was added. What the hell?

Mo Qing and Feng Wu came side by side.

This boundless grace suddenly turned the Lin family courtyard into a wonderful place on earth.

Xiaotao didn't have enough confidence, so she shrank to the side.

Xing'er's self-positioning has never changed, and she stands with a bow.

Cui Ying was a little timid. She always wondered why these two women were so beautiful and holy. But Lu Yi quietly pulled her. Cui Ying looked sideways and saw Lu Yi's tall breasts. She felt confident. What are you afraid of? You two saints or the master of the pavilion, I am My husband’s little daughter-in-law! authentic!

As a result, she was also in high spirits.

Only the autumn water painting screen on the attic stood up slowly, like a holy fairy.

In terms of confidence, beauty, and moral foundation, she is also a person who is comparable to the genius of the Holy Family.

Pavilion Master Feng Shao! Lin Su bowed slightly and said with a smile: When did you come to Haining? I didn't know.

Feng Wu smiled sweetly: I heard that the Mo family's sister was abducted, and I was a little worried that she was being harmed, so I came to take a look.

It's not good for Pavilion Master Feng to say that. Saint Mo came to Haining just to discuss literature and art. How can such an open-minded spirit of exploration be as unbearable as you say?

The two women laughed at the same time.

When they smiled, the atmosphere in the courtyard suddenly relaxed.

Sister Chen smiled softly: Please come into the pavilion and try the Lin family's new tea.

The two girls sat down and Xing'er brought new tea.

This is the authentic Qingming tea, collected from Meiling, made by Cui Ying with skillful hands, and regarded as the top grade of the Lin family.

Exquisite new tea, exquisite beauties, and excellent poems. No wonder Mr. Lin, even though he has many official career, he always goes home when he has free time. Mo Qing glanced at the two walls. On the two walls, two poems by Lin Su were engraved. Butterfly Loves Flowers.

Lin Su held up the teacup and greeted him: A boat traveling thousands of miles will eventually find its way back. Home like mine is the harbor for the boat.

Master Lin said it well! Mo Qing said: The boat travels thousands of miles, and home is a harbor. It has been three months since I left Moxin Lake. I also want to return home as soon as possible. I wonder if I can fulfill the promise you and I made in advance.

Can!

As soon as the word Lin Su came out, the hearts of all the girls jumped.

Mo Qing was abducted by him to Haining Academy. It was an absolute secret in Haining Academy. Even Baoshan didn't know that the teacher Lin Qing in the martial arts class was a woman.

But all the women in the Lin family's west courtyard knew about it.

And they also knew that what Mo Qing was looking for was the crown of the arithmetic system - the round square problem.

The problem of the circle and the square is an unsolvable problem.

They didn't know if Lin Su could really figure it out, or if he was just using it as a gimmick to kidnap Mo Qing.

But now, Lin Su agreed.

In other words, today is the time to reveal the mystery.

The problem of the circle and square, a problem that has troubled arithmetic wizards all over the world for thousands of years, may create a miracle today...

Mo Qing was the most excited.

The tip of her nose was sweating...

She is literary! In the literary world, sweating on the tip of the nose is simply an eternal spectacle. Feng Wu could have teased her, but at this moment, Feng Wu was also excited...

Lin Sudao: To solve the problem of round and square, we need to first implant a concept called area. What is area? The popular understanding is how much land it occupies. I divide all planes in the world into three types, namely square , triangles, circles, and other irregular shapes can actually be split, but in the end they are still these three...

The pavilion was as quiet as night, and the eyes of the women were all bright.

Even Myolie, who has the worst background in arithmetic, understands it, because she is from the Lin family, has been exposed to high-end things, and is no stranger to arithmetic.

The various shapes Lin Su drew casually on the table, after his explanation, can indeed be divided into three categories: shapes, triangles and circles.

After talking about the splitting of plane graphics, now comes the key formula. If you master this formula, you can accurately know the area of ​​various graphics. Let's talk about the simplest one first, the square! The formula for calculating a square is length times width... Based on this table For example, Saint Mo, please measure the length and width of this square table.

Mo Qing had fully entered the state. As soon as he took out the measuring ruler in his hand, he quickly got the accurate result, which was five feet seven inches long and three feet two inches wide.

What's the area?

With a flick of Mo Qing's hand, an abacus separated from the measuring ruler, and with the snap of beads, the result was quickly obtained: 1824.

Measure the area of ​​this jade pendant again!

Lin Su casually threw over a square jade pendant.

The area was quickly calculated: 36!

The first question is, if this table is covered with this kind of jade pendant, how many jade pendants are needed? The calculation formula is, the area of ​​the table is divided by the area of ​​this jade pendant.

The abacus clicked, and the result came out quickly: a little over 50 yuan.

Verify it to see if it's accurate.

Mo Qing waved his hand lightly, and the jade pendant in front of Lin Su was suddenly copied 49 times. 50 jade pendants were spread on the table, one piece not too much, one piece not enough.

Mo Qing's face suddenly turned red, and her blood flowed at least twice as fast as usual.

She has touched upon the ultimate solution to the problem of the square, and all that is missing is just a little bit...

Lu Yi's face also turned red. She was the best arithmetic person in the entire Lin family besides Lin Su.

Only Feng Wu was completely confused. She didn't understand everything in front of her!

She didn't understand what multiplication was, what division was, she didn't understand the tool Mo Qing used just now, and she didn't understand what area was. Everyone in the pavilion felt like hearing about the great road, with joy in their bones, but she was the only one who was confused. over there.

Oh my god, I’m only half-stepped in the literary world. There’s no reason why I can’t be as good as a girl, right?

Am I crazy, or is the world crazy?

Mo Qing slowly raised his head: With square terrain and square bricks, I can calculate it as long as you give me time, but I'm not as fast as you. The real problem is the question of round squares. How to calculate the area of ​​a circle?

The only difficulty in the question of the square of a circle is: the calculation formula for a circle. This formula is: multiply the radius of the circle by the radius, and then multiply by 3.1416!

A long calculation...

Mo Qing stared at the countless squares in a circle deduced by the measuring ruler, and his chest rose and fell sharply...

The problem of round and square has a solution!

The tragedy that happened to her father that day could actually have been avoided!

She traveled thousands of miles just to find an answer, and she got it today!

From now on, Mohism can push Mohism to a higher level at an academic level!

At some point in the sky, a ray of holy light shrouded the Tingyu Pavilion. Above the Tingyu Pavilion, golden lotuses bloomed, and there was peace between heaven and earth. It seemed that the people in the temple were also extremely happy for the answer to the round square problem.

Tears quietly moistened Cui Ying's eyes.

Dad, Mom, can you think of it?

My daughter left home thousands of miles away and found the most amazing man in the world!

At this moment, a hand gently pulled her.

Cui Ying turned around and saw Xiaoxue.

Xiaoxue came to her ear and whispered something. Cui Ying's face suddenly changed and she slowly left Tingyuting...

In the Tingyu Pavilion, Lin Su said: I said that the shapes in the world can be divided into three categories. You already know the formulas for calculating the areas of squares and circles. Now it is triangles. The formula for calculating triangles is...

This explanation truly explains the principles of geometry.

Mo Qing's heart turned from excitement to clarity. As he said, the world's graphics can be divided into three categories. Mastering these three calculation formulas, not to mention the complete solution to the circle and square problem, even the more difficult deformation of the circle and square Questions, all are covered by one method and all methods are accessible.

The golden lotuses on the Tingyu Pavilion are blooming, and lotuses are growing under Lin Su's feet. The golden lotuses are cheering in the air. Everyone in the Lin family is staring at the Tingyu Pavilion. Everyone in Haining City is also staring at the Tingyu Pavilion. Boats are sailing on the river. He also stopped the boat and watched...

There was only one small boat that left the shore and headed for Beichuan, Yishui. On board was Cui Ying. Her tears kept flowing down her face...

The golden lotus finally dissipated.

Mother Lin's stretched-out neck finally retracted.

On the Tingyu Pavilion, Mo Qing stood up and bowed deeply.

There are no words of thanks, everything is in one bow.

Master Lin, originally I wanted to leave Haining and return to Moxin Lake today, but now I have changed my mind and I want to stay.

Why?

Because I want to finish the second volume of your arithmetic!

Lin Su smiled: Did you know there is a second volume of arithmetic?

It's natural! Whether it's a circle or a square or a triangle, they are all practical applications. The basic theory should be in the second volume of your teaching for Haining Academy's art class.

Haha, Lin Su laughed loudly, raised his hand, and handed two books to Mo Qing.

The first middle volume of Arithmetic, the second middle volume of Chinese Language...

This is the textbook I compiled for Haining University for the next academic year. You can read it first, and then make 10,000 copies to prepare for the students!

good!

As soon as the word good came out of his mouth, all the girls in the pavilion were stunned.

Oh my gosh, not only has she been kidnapped for three months, it looks like it has been extended...

Mo Qing said goodbye.

Before leaving, Feng Wu moved her mouth, as if she wanted to say something, but in the end she said nothing and followed Mo Qing.

Lin Su stared at the backs of the two women, with a smile on his lips. How do you describe this smile? In Lu Yi's words, it's the kind of smile a fox would have when facing a little chicken...

Mr. Sir, congratulations. It seems that Saint Mo is abducted, and from what I can see, the Feng Shao Pavilion Master also seems to have the consciousness of being abducted...

As soon as these words came out, the eyes of all the women in the pavilion had something strange...

Lin Su looked at this and that: Hey, where is Ying'er?

Don't come here, just change the subject when you encounter a question you don't want to answer... Green Yi gave him a blank look, turned around, and was slightly surprised, where is Ying'er?

…

In a residential house in Beitan, Yishui, a ragged old man held a bowl of porridge, his throat sliding up and down. The sweet porridge felt like heaven to him.

In the past month or so, he traveled thousands of miles from north to south. Wherever he went, there were human tragedies. His clothes had long been rotten to pieces, and his stomach had long forgotten the taste of serious food. The sky was filled with floods and corpses were strewn across the fields. He passed by wild dogs that gnawed on corpses again and again. He thought he would eventually reach the end of his life.

However, a place called Yishui Beichuan changed his destiny.

When he arrived here, it was as if he suddenly saw a fairyland on earth.

Neat houses, neat fields, everyone wearing unpatched clothes, everyone has a moving smile on their face.

He once thought that these were the family members of high-ranking officials, but after hearing their introduction, they turned out to be refugees from the north.

As soon as he spoke in his native accent, these refugees showed unimaginable kindness to him, letting him live in their room and bringing him rice porridge. But when he accidentally mentioned a person's name, everyone was surprised. The ground was stunned.

He didn't know if this was a blessing or a curse, why everyone had this look on his face when he mentioned his niece's name...

Cui Ying followed Deng Bo to Beichuan, Yishui...

She had walked through the familiar flower path countless times, but today, she was very nervous...

Pushing open the door, the old man inside raised his eyes, and suddenly his whole body was shaken, and the porridge bowl in his hand almost overturned...

Ying'er!

uncle!

Cui Ying ran over, tears streaming down her face again.

Ying'er, why are you here? I...I thought you were gone...

Uncle, please tell me quickly, how is my mother...how is my mother?

Uncle let out a long sigh...

After Cui Ying left home that day, her father was worried and chased her out, eventually dying on the road to exile. The story of Cui Ying selling herself to bury her father was spread back to the Lei family in Dongzhou through the mouths of the refugees.

How could her mother bear the news? I can't afford to be sick.

The Lei family has also fallen out, and the son-in-law is gone. What does the concubine taken by the son-in-law and the children born by the concubine have to do with the Lei family? Why do you live in Lei's house when you have no relationship? It was acceptable for both uncle and Cui Ying's mother to drive them away, but what the Lei family wanted to do was too much. They wanted to sell Cui Ying's sister Cui Miao to a brothel.

Her sister is only thirteen years old!

So, last winter night, when the moon was dark and the wind was high, the uncle carried her mother on his back, and the brother led the sister, and the four of them escaped from Lei's house overnight.

He hid in the deep mountains and forests and lived in a broken Taoist temple for a whole winter.

That winter, my uncle learned how to dig traps to catch rabbits, and my brother, a scholar, also learned how to chop wood, and learned medical skills from an old hunter. In this way, my mother was pulled back from the brink of death and survived until the beginning of spring.

Seeing that the four of them could start their new life on Beiliang Mountain, the Lei family found them. They still wanted to sell the girl to a brothel. Cui Ying's brother was furious and killed her with a hatchet. The second son of the Lei family was wounded by a chop. This chop made him irrecoverable. The government officials came and took him to prison.
