Qin Ke continued: "Then I understood why the ancients were so obsessed with 'leaving a name in history'. After a person dies, he can leave nothing behind and take nothing away except his reputation. I also want to 'leave a name in history'."

"I was still young at that time, and I didn't think of any way to 'leave my name in history'. But when I saw great people like Newton, Euclid, and Edison, I suddenly got inspiration. Otherwise, I would start with the best grades.

Let’s start as a god of learning. In the future, I will become a scientist or inventor, create some of the most common theorems, and invent some of the most commonly used things. Even thousands of years later, humans will remember my name whenever they use these things. For example, see

When you look at electric lights, you think of Edison; when you study mechanics, you think of Newton; when you study mathematics, you think of Euclid; when you use computers, you think of Bill Gates..."

"Since then, I have embarked on the road of no return with the goal of becoming a god of learning. Haha, school committee, do you think this is particularly naive? In fact, even now, I still have such thoughts, but I have more responsibilities. God has given me

Given this opportunity, I have to try my best to make my life more meaningful."

Naturally, Ning Qingyun didn't know that the "opportunity" Qin Ke meant was the "School God Saves the World" system. She thought he meant "having a healthy life" or something like that, so she nodded in approval.

"Study Committee, as you said before, there is a sentence in Ultraman Tiga, 'Try to live a short life and leave the achievements to future generations to inherit.' I am more greedy. I hope that my life

I have rich and colorful experiences, and I hope that everyone around me can live a happy life because of me. At the same time, I also want to leave some academic achievements and some scientific and technological inventions, especially things that can truly improve human life, such as leading a new energy revolution, such as

Decipher the mysteries of time and space, allowing humans to go into space, or cross dimensions..."

"Haha, the more I talk about it, the more it sounds like science fiction, but I really think that when someone writes my biography in the future, they will write something like this, 'This is a great scientist who guided the scientific development of mankind and enabled

Humanity's scientific and technological civilization has made great strides forward. He has solved many unsolved academic problems. His research and inventions have made human life more convenient. He has changed human life patterns... Please remember it forever.

This incredible Xia scientist, his name is Qin Ke'!"

Ning Qingyun's eyes sparkled when she heard this. She really liked seeing such a confident and assertive Qin Ke.

While she was still focusing on exams and competitions, Qin Ke's eyes were already focused on such a great and glorious goal.

And the amazing thing is that she didn't doubt whether Qin Ke could achieve such an ambitious goal, or in her heart, as long as she kept working towards such a goal, it would be the greatest life.

She lowered her eyes, hiding the admiration and excitement in her eyes, and asked softly: "So you started writing academic papers and compiling mathematics learning materials that are most suitable for junior high school students? Is this the first step to achieve this goal?

One step?"

Qin Ke was startled, then smiled softly, nodded and admitted without shame: "Yeah."

Although it is a task issued by the system, it is indeed consistent with his goal. What if he admits it? Why can't he admit it?

"So thank you very much, Academic Committee. When I wrote the paper, you helped me revise the words and format. I wrote the study materials, and you helped me with suggestions and revisions."

The girl smiled sweetly and rested her little head in Qin Ke's arms: "It is my honor to be able to participate in such a great cause as yours."

Qin Ke kissed her hair and said warmly: "Of course, I have a bigger and more important wish. I hope to add this sentence at the end of my biography, 'But compared with the achievements in scientific invention

Qin Ke believes that the luckiest and most proud thing in his life is that he has never let go of the hand of a girl named Ning Qingyun beside him, and has seen all the beautiful scenery in the scientific world with her.

."

How could a seventeen-year-old innocent girl withstand such sweet love words? It was so sweet that her heart almost felt like it was stained with honey.

Ning Qingyun's eyes flashed with rainbow-like blurred colors, and she didn't know how to express the love in her heart at this time.

She secretly glanced at the fashionable girl next to her who was fascinated by the Korean drama, and finally had the courage to move towards Qin Ke's lips quickly.

A kiss as green as a dragonfly touching water, but it reveals the most touching emotions in the heart of a reserved and proud girl.

"This will also be the luckiest and most proud thing in my life." The girl said softly before burying her hot face in Qin Ke's arms.

…

Dingxiu Mountain is a famous scenic spot in Huahai Province, but now it is the off-season for travel, and there are not many tourists. Qin Ke and Ning Qingyun visited the mountains and rivers of the scenic spot, leaving laughter and laughter in the beautiful scenery.

Took a lot of group photos.

However, the two of them were too conspicuous, especially Ning Qingyun, who was pretty and pure, with eyes as clear as the clear sky. She was very eye-catching. Many tourists pretended to take pictures of the scenery and secretly took photos of the two of them.

Ning Qingyun also noticed it, maybe because she felt shy or because she was attached, she never let go of Qin Ke's hand.

The girl's physical fitness was still not very good, and she often had to take a break after walking for half an hour. But after blushing and sweating, Ning Qingyun became a little more charming and charming. There were even a few photography enthusiasts carrying SLRs and asking politely.

Take a photo of Ning Qingyun and take part in some photography competition as an entry photo.

Ning Qingyun shook her head and hid behind Qin Ke. Qin Ke declined, and the photographers had no choice but to leave with regret.

These little episodes did not affect the mood of the two of them. When they saw a Taoist temple in the scenic spot and heard passers-by discussing in low voices that the marriage lottery in the Taoist temple was very good, Ning Qingyun blushed and dragged Qin Ke there.

I asked for a signature.

Qin Ke knew the secrets inside and winked at the Taoist who interpreted the signatures. When Ning Qingyun wasn't paying attention, he secretly donated five hundred-dollar bills to the incense box. The Taoist who interpreted the signatures immediately praised him and said that it was absolutely superior

The smile on Ning Qingyun's lips never disappeared.

This chapter is not over yet, please click on the next page to continue reading! The Taoist interpreter also used a red rope to tie their wrists together, saying that if they were not disconnected at the bottom of the mountain, it would be even more perfect.

Qin Ke took a look and saw that the red rope was very strong and could not be cut easily with scissors. However, Ning Qingyun decided not to stay on the mountain anymore and pulled Qin Ke down the mountain, always being careful and safe.

When she arrived at the bottom of the mountain, she saw that the red rope tying their wrists was intact, and she smiled happily with relief.

Qin Ke felt funny in his heart, you girl is still targeting great scientists and you still believe this.

However, he could also feel that the girl valued and cherished the relationship between the two of them, and his heart was full of tenderness. Naturally, he would not say anything disappointing. Instead, he followed the Taoist's words and coaxed him to make Ning Qingyun happy.

Her mood couldn't be better, so she kissed him sweetly.

The two played for two days and one night before taking the high-speed train back home.

When it comes to what was the most unforgettable part of the entire trip, Ning Qingyun might say it was the experience of traveling somewhere, or the pleasant walk the two held hands by the big lake near the hotel in the evening, blowing the breeze.

But Qin Ke will definitely tell the story that happened in the hotel.

Considering safety and various considerations that are not common to outsiders, Qin Ke booked a double room, which meant that he and Ning Qingyun slept in the same room with two beds.

But Qin Ke is still more disciplined. Ning Qingyun, a shy and conservative girl, must not be impatient. It is not easy to let her get used to such a double room first, especially when the girl is still blushing and obedient after taking a bath.

She put on the short skirt Qin Ke bought, which made Qin Ke even more satisfied.

…

After the sweet date, Qin Ke returned to school. In addition to guiding Ning Qingyun's IMO, Qin Ke's main focus was on formally advancing his task of writing junior high school mathematics learning materials.

At this time, he had bought all the junior high school mathematics textbooks from all over the country, and used his free time to read them carefully. He had a clear understanding of the advantages, disadvantages and knowledge points of all the textbooks before he started to take action.

Ning Qingyun was also interested in helping.

After discussion, the two decided to break up the mathematics knowledge from junior high school into it in the form of a story.

As long as junior high school students understand their carefully designed story plots, they will basically be able to learn the corresponding mathematical knowledge points. With the help of the questions and answers behind each short story and the accompanying exercise booklet, they will be able to master these knowledge points proficiently.

Thus, a teaching aid storybook called "Cat Lemon and Puppy Keke's Wonderful Math Journey" was born.

The first part written for the first grade of junior high school.

Qin Ke is responsible for the scientific combing of the mathematical knowledge in the story, the arrangement of the exercise book, and the content of the story by Ning Qingyun.

In order to prevent the story from being too childish or too serious, Ning Qingyun also bought a copy of "Puppy Money" for reference.

Every time a story is written, the two of them will discuss and revise it over and over, striving to be interesting, vivid and permeated with mathematical knowledge points. After the final draft is finalized, Ning Qingyun will copy it into a specially purchased A4-sized bound book with Juanxiu's beautiful handwriting.

.

As for the cover and illustrations, Qin Ke found his younger sister Qin Xiaoke, who has a strong artistic talent and has been good at painting since she was a child, to be in charge.

Originally, he had to think about what kind of promises to make, or even "promise huge profits" to persuade this lazy girl to help. Unexpectedly, Qin Xiaoke agreed easily, without even mentioning any conditions, just asking.

If you know the details to be drawn, you will start immediately.

This surprised Qin Ke.

It is said that this little girl seems to have grown up since the last time she came to the city to meet Ning Qingjun. Her parents said that she actually started to take the initiative to read and do homework at home, and her recent monthly test scores have also steadily improved.

, but from Qin Ke's point of view, Qin Xiaoke has not changed much. If anything, it is that he chats with him on WeChat less frequently, and instead sends WeChat messages to Ning Qingyun.

Ning Qingyun also mentioned to Qin Ke that Qin Xiaoke would send her several WeChat messages every day to chat, and the relationship between the two was good.

Qin Ke is happy to see his sister's growth and the closer relationship with Ning Qingyun, and will not interfere.

The busy work between him and Ning Qingyun lasted for nearly three weeks.

Especially in early June, when the school was on holiday during the week before and after the college entrance examination, Qin Ke and Ning Qingyun, apart from taking a day out to go shopping and date, spent the whole day in Green Cuiying Juli compiling this study material.

By mid-June, the more than 100-page "The Wonderful Mathematical Journey of Kitten Lemon and Puppy Keke (Junior Chapter 1)" and its supporting exercise book, which included mathematical knowledge points for the first and second semesters of junior high school mathematics, were officially released.

Completed.

Probably they would not have imagined how far-reaching this handwritten pamphlet and its subsequent second and third chapters would have in the future; and they never imagined that this booklet would be translated into dozens of languages ​​in the future.

, swept the world and became the most popular popular mathematics reading book for primary and secondary school students in the next hundred years. Its influence is far-reaching, even surpassing "The Little Prince" by French writer Antoine de Saint-Exupéry.
Chapter completed!
