Seeing that his daughter, who had never liked mathematics, seemed to be fascinated by the book, the father couldn't help but turn to the first page and start reading.

After reading the first three chapters, he suddenly said to his wife: "Honey, this fairy tale book is interesting. It's completely different from what I imagined."

The mother had also been reading, and she looked away from the book with nostalgia: "Yes, it is quite interesting. I thought it was for children, but I actually read it with gusto and innocence.

It's interesting, has a good perspective, and the plot of the story is very clever in integrating mathematical knowledge into it without any sense of violation. You will remember these knowledge points after reading the story. It's amazing! These two genius high school students are really amazing!

"

The father looked at the exercise booklet in the last appendix and became more satisfied, but he deliberately pushed his daughter who was looking at it in awe: "Ayi, do you think you should buy this book?"

"Ah? Dad, what did you say?"

"I asked if I should buy this book?"

The daughter said sheepishly: "How about... should I buy it?" Her tone was uncertain, but she held the new book tightly in her hand.

The parents smiled at each other, did not make fun of their daughter's "fickleness", and took their daughter to the checkout counter.

Similar situations occurred repeatedly. In just an hour or so, nearly fifty copies of this set of teaching aids for the first grade of junior high school were sold, basically to children of appropriate age.

After watching this scene from a distance, the general manager and editor-in-chief of Yingyuan Education Group Publishing House looked at each other and saw the surprise and relief in each other's eyes.

Such a high payment rate is simply amazing.

You must know that this is teaching aid material for the first grade of junior high school, and it is after nine o'clock in the morning on weekends, when the flow of people is not too large.

The fatigue of the two people who had been standing for an hour was gone. However, their tense hearts had relaxed a little. They simply ran to Starbucks opposite, ordered two cups of coffee, and continued to observe.

The closer it gets to noon, the greater the flow of people in the bookstore, and most of the parents who stopped there have paid. Including parents with primary school students, after browsing for a long time, they actually bought it.

The more people gathered around the promotional display board and bookshelf, the more attention it attracted. Many passers-by stopped and gathered around curiously, making the front of the bookstore become a little lively.

The eyes of the general manager and editor-in-chief showed unconcealable excitement.

Stable!

After a rough calculation, they found that this bookstore had sold nearly 400 copies this morning alone!

If you put it nationwide, it shouldn't be a problem to sell 50,000 copies!

This is only half a day’s data!

…

At around three o'clock in the morning on Sunday, the lights of Yingyuan Education Group Publishing House were still bright, the first-day sales data on Saturday were being calculated nervously, and a group of editors were checking the response online.

As a result, whether it is an online e-commerce platform, a forum, or a scarf, the response from readers is basically positive.

[Passing by the bookstore, I accidentally saw that Qin Shen and Ning had published a book. The price was quite cheap. I thought about buying it home for my sister, but I was fascinated by it while riding in the car. Hahaha, Lemon and Ke Ke are so cute.

Is there any!】

[I didn’t expect that teaching aids could be written in this way. It was an eye-opener. It was very lively and interesting. Anyway, I laughed the whole time and read it, just like reading a picture book story. Huh? It seems that I also reviewed the mathematics of the first grade of junior high school without knowing it.

(dog head)]

[I am a student who is about to enter the first year of junior high school. My dad bought it for me today. I was still very unhappy, but my dad pressed my head and read two chapters. The result... it tasted so good! I didn’t even eat.

I’ve finished reading it! I’m excited to comment, and I plan to read it again later. PS: I feel like I can do the attached first-grade math study booklet, haha!]

[The illustrations are cute, the story is interesting, you can learn mathematics, and the key price is so cheap. I felt sorry for the fruits of Qin Shen and Ning’s work... So I went to the class group to recommend it! 】

[My mother bought it for me to watch, but now my brother and I are fighting over it... Damn it, you can't let my sister do it! 】

[Looking forward to the second grade of junior high school article! I will be in the second grade of junior high school in a few days. After reading this fairy tale book, I looked at the original mathematics textbook again, and it was boring!]

[I thought it was about young people looking for money, but after reading it, I was surprised that it was good. It is better to eat it with the after-school exercises. Oh, I am a junior high school mathematics teacher. I feel that if every student in the class has a copy, it will be much easier for me to teach the textbook.

.]

[The explanation about pricing on the back cover made me stand in awe of these two students. Incidentally, I also gave a slight X to show respect to the publisher for agreeing to such a request. 】

Seeing these good reviews, one of the publishing staff couldn't help but ask a colleague in the publicity department: "Is this the troll you hired?"

A colleague from the Propaganda Department spread his hands: "Didn't you hear in yesterday's meeting that 80% of the publishing house's working capital was used for printing and transportation? Do you think we still have enough funds to hire trolls? We even hired websites and big Vs to post soft articles.

All the money is gone, so I manually mobilized my relatives and friends to convert friends and wear scarves..."

Publishing staff: "...In other words, these are all true reviews?"

"99.9999% tap water."

The editors who heard the conversation smiled proudly, but the rest of the staff were shocked.

In the publishing department on the other side, the phone kept ringing.

"Yes, don't worry, we still have stock here and will send it out as soon as possible. You can receive it tomorrow evening."

"What? Your bookstore is all sold out and you want to place an additional order? But basically all the stock in our inventory has been pre-ordered... You said you can pay in full first? It will be credited to your account right away?"

"Hello? This is Yingyuan Education Group Publishing House... Do you want to add orders too? You guys have sold out too?"

Listening to the sound coming from the publishing office next door, everyone looked at each other in shock... Is it that exaggerated? There is actually a bookstore that has sold out of stock?

The stockings of publishing houses are generally determined based on the size of the bookstore, and it is rare for books to be sold out on the first day.

"The first sale is out!" A loud shout made everyone stop talking and stand up.

The statistician stared at the computer screen and announced in a trembling voice: "The first sales figure is... 326,000 copies!"

Everyone present was stunned for a long time, and then cheers resounded throughout the conference room!

Even if they overestimated the value of this set of teaching aids, they never expected it to sell so well!

Taking advantage of the opportunity when Qin Ke and Ning Qingyun’s fame is exploding to release this book is indeed the right decision!

The director of the distribution department wiped the sweat from his forehead and said with pain and joy: "According to this trend, our inventory will be gone tomorrow... Manager, we must print more!"

"Then we will print more and ask all bookstores to pay for the goods first and ship them in the order of payment! At the same time, notify the printing department to print an additional 500,000 copies!" The general manager suppressed his excitement and looked around the crowd and said: "

If you still have energy, come and have supper with me, the company will cover everything!"

"Long live--!"

Everyone cheered again, not just for a late-night snack, but for the bonus that seemed to be in their pockets!

Although this set of teaching aids is priced cheaply, each set actually has a profit margin. As the scale increases, the profit margin will increase. The most important thing is that the reputation of Yingyuan Education Group Publishing House will be built!

In the next few days, as the Internet became more and more popular, the sales of "Kitten Lemon and Puppy Keke's Wonderful Mathematical Journey (Part 1)" continued to rise, further pushing up the popularity of Qin Ke and Ning.

Qingjun's reputation spread by word of mouth to countless parents, who rushed to buy it. It turned out that it was hard to find a book. The publisher repeatedly added more printings, but still could not meet the huge market demand.

A week later, the first-week sales record was released. The sales volume of "Kitten Lemon and Puppy Keke's Wonderful Math Journey (Elementary Chapter 1)" actually exceeded 5 million, breaking the first-week sales record of teaching aids in academic circles across the country.

Sales records and reputation are rising steadily, with more than 200,000 ratings on Douban, and a total rating of 9.8.

There are countless people frantically urging for updates.

[Ah ah ah, Qin Shen and Ning students should hurry up and publish the second and third grade chapters of junior high school. My children will start school soon! She said that she can’t stand the boring mathematics textbooks now!]

[I am in the third grade of junior high school, but I have read the first chapter of the first grade five times, and then I took the test paper for the first grade of junior high school, and I got a perfect score easily! You must know that I have never passed mathematics since I entered junior high school! Thanks to brother Qin Ke and sister Ning Qingyun!

】

[Qin Shen, classmate Ning, please beg for an update! We are all genuine readers who bought your book, not pirated readers! Please reply when you see the message!]

[It’s best to publish the first, second and third grades of high school as well, the vast number of high school math scumbags are waiting for your rescue!]

[Also, can the price be raised a little? There are more than 270 pages, nearly 200,000 words, and such exquisite arrangement of knowledge points. I feel embarrassed and seem to be looking away...]

Of course, it wasn’t all good reviews. Some jealous people in the education sector also said some weird things, such as “How unbecoming! It doesn’t have the seriousness of teaching aid materials at all!” and “The plot of the story is ridiculous, and it actually uses small animals as the protagonists.

?Your dog and cat know math?”…

Many netizens took the initiative to stand up and retorted: "It's nonsense, is it entertaining and educational? Do you understand?" "P's family, how many cartoons have animals as the protagonists, why don't you criticize them?" "You're full after you eat them.

Or are you narrow-minded? Hehe, have you been slapped in the face by a high school student? Are you feeling embarrassed and angry?" "The teaching aids you compiled are expensive and boring, and you have the nerve to complain?!"

Amidst the noise, there was no news from Qin Ke and Ning Qingyun. It was not until the seventh day that a scarf was released at the same time:

"Thank you for your trust and support in our book "The Wonderful Mathematical Journey of Kitten Lemon and Puppy Keke (Part 1)". We have decided to use all the 400,000 yuan royalties for printing this book to purchase this book.

And donated it to the library of a mountainous middle school through the 'Hope Project'. We are weak, but we hope that the light of mathematics will shine brighter and brighter on the land of Xia Kingdom. I hope that more and more seeds of mathematics can take root and sprout, and eventually make

Our Xia Kingdom’s mathematics is at the top of the world!”

The two scarfs quickly set off the Internet, with countless netizens frantically liking and retweeting them, and those "brickheads" who had said weird things before were almost driven into isolation.

[Well done, both Qin Shen and Ning are well done!]

[I’m so touched, I’m a huge fan of you two now, what should I do?]

[Following the fire, the students in our class also decided to buy ten copies each and send them to the libraries of nearby village primary schools and village middle schools!]

Even the official media commented: "Why did the teaching aid materials written by two high school students arouse such widespread praise? This deserves countless education experts to study carefully and think deeply. We believe that this is the profound understanding of mathematics in this book."

Love, with a pure heart to spread mathematical knowledge! They squatted down and thought about how to resonate with the students from the perspective of students, and how to make those children who have no mathematical talent quickly learn knowledge points!

It’s not about publishing books to gain academic achievements! Qin Ke and Ning Qingyun, well done to you!”

One comment instantly attracted countless likes, and at the same time, it also pushed the fame of Qin Ke and Ning Qingyun to a level comparable to that of top stars.

…
Chapter completed!
