Shen Tiantian is only half a year older than Qin Ke. She is currently a sophomore at Chengkong Private High School and is in the same class as Qin Ke.

However, when she took the entrance exam for Chengkong High School, she failed by a few points and had to pay tens of thousands of yuan in sponsorship fees to successfully enroll. So when the news that Qin Ke was admitted to Yingyuan Private High School came back to the town, Shen Tieshan did not Don't use Qin Ke to teach her a lesson, which makes Shen Tiantian particularly unhappy.

What's more, Sakurazono and Seikora are bitter rivals, and students from the two schools also look down on each other. One thinks the other is a nouveau riche with no background, and the other thinks the other is a self-proclaimed yesterday's flower.

Shen Tiantian was originally displeased by her cousin's careless appearance, but now his words became more tit-for-tat.

Qin Xiaoke poked his head out from behind Qin Ke and muttered unconvincingly: "My brother is really good at math! Huh, just a math Olympiad is nothing!"

In her heart, her brother is number one in the world. It’s okay to look down on her, but it’s not okay to look down on her brother!

So even if her grandfather, who is usually the most fearful, is present, she can't help but speak out to criticize her cousin.

Qin Ke rubbed his little sister's hair and signaled her to stop talking. He smiled and asked, "Oh, not yet. Can I participate by signing up by myself?"

Shen Tiantian glanced at Qin Xiaoke, who was unconvinced, and said loudly: "Of course not, you have to pass the school selection to participate. Our Chengkong won the top three in the municipal preliminary competition last year, and this year's preliminary contestant selection competition It was very intense, and several classmates and I attended the Olympiad coaching classes half a year in advance before passing the school selection."

Shen Tiantian pretended to be humble and mentioned that she "attended the Olympiad coaching class for half a year," but the real purpose was to prove how fierce the competition was and how powerful she stood out.

Qin Ke was so funny, he thought of Ning Qingyun for some reason.

Although Ning Qingyun is a little noble, he doesn't have this arrogance to show off, and makes people feel much more comfortable.

"Speaking of which, is there any prize money in this Olympiad?"

"Yeah, the first place at the municipal level will get a reward of 10,000 yuan, and the reward for the provincial semi-finals will be even more. I heard that the first place will get 50,000 yuan, and in the national finals, the first place will get 100,000 yuan. These are not counting the additional rewards given by the school."

"So much bonus?" Qin Ke's eyes immediately lit up. He didn't expect the bonus from the Olympiad to be so good. This is the best way for the student party to get rich!

Qin Ke has not been able to get a scholarship from Yingyuan High School for more than a year. In the past, there were few scholarships for schools in mountainous areas. He spent money generously and has already spent most of it. It seems that if he wants to satisfy Qin Xiaoke's wish for a fruit notebook, he has to rely on himself. This Mathematical Olympiad has come true.

"What, Qin Ke, are you interested? If you can pass the school selection and successfully register, your cousin will lend you some exercise books for the Mathematical Olympiad. But the Mathematical Olympiad is not exam-oriented mathematics. You can't even understand the questions without special training. …”

Shen Tiantian seemed enthusiastic, but the sarcasm in her tone was very obvious.

Qin Ke motioned to his younger sister to get his schoolbag. After taking it, he took out the "Math Olympiad Registration Form" that he had filled out last night and asked, imitating Ning Qingyun's calm expression and tone:

"Cousin, is this the Mathematical Olympiad registration form you just mentioned? Our math teacher gave it to me. I haven't filled it out before. I don't know if I filled it out wrong. Can you help me take a look?"

Shen Tiantian was about to say a few more words of ridicule, but Qin Ke slapped her words back in her stomach. She took it with some disbelief, and it turned out to be the "Math Olympiad Registration Form".

The world attaches great importance to results, and competitions like this are even more rigorous. Each registration form has an anti-counterfeiting mark and a unique number, making it impossible to copy or forge.

Shen Tieshan, who had been silent next to him, glanced at it and said with a snort: "It's okay, it's the recommended registration form." He is the honorary consultant of the provincial semi-finals organizing committee of the High School Chemistry Olympiad, and he has a very good reputation.

Shen Tiantian's face suddenly felt a little hot.

Of course she also knows what an "unofficial recommendation registration form" is. Unlike her own registration form, which was filled out after passing the selection and sent to the school for review, Qin Ke's registration form can only be obtained by "unofficial seed players"! It means no need to participate in the selection!

The most typical sign is that Qin Ke's registration form has a "recommender" column at the bottom, and the math teacher's name has been signed in advance and the school's official seal has been stamped!

This kind of pre-determined recommendation registration form is specially issued by the Mathematical Olympiad Organizing Committee. The number in each high school is extremely limited. For example, Chengkong High School only has about ten copies, so the mathematics teachers will only send them to the most promising students.

The top math student in Shen Tiantian's class had a copy, which made her envious and jealous for a long time. She didn't expect that her cousin would have a copy. Looking at his uninformed look, he didn't seem to know what he was getting. The value and significance of the "default recommendation registration form"!

My cousin, who was careless and lazy, actually became so good after entering high school?

How can it be!

"So my cousin is so good." Shen Tiantian rolled her eyes, opened the Mathematical Olympiad exercises in her hand, pointed at one of the questions and said, "Can you help me look at this question? I don't understand something."

Qin Ke glanced at it and saw the title:

"Is there such a polyhedron that has an odd number of faces and an odd number of edges on each face?"

"Cousin, this is a graph theory question. It is very simple to solve. You can easily come to the conclusion that it does not exist."

Shen Tiantian: "???"

She looked at the topic she was pointing at and realized that she had accidentally turned to the wrong page. She had never read this question before. She only had a vague impression of "graph theory" and seemed to have heard about it in a training class. , but I can’t remember it for the moment.

"We assume that there is such a polyhedron, then use vertices to represent the faces of this polyhedron, and only when the two faces represented by vi and vj have common edges, connect an edge between the corresponding two vertices of graph g. According to the meaning of the question It can be seen that each d(v) is an odd number, so the sum of the degrees of the odd vertices is also an odd number, which obviously violates the theorem, and it can be disproven that there is no such polyhedron."

Shen Tiantian quietly took back the book and turned to the answer page, which was almost exactly the same as what Qin Ke said.

Shen Tiantian couldn't help but ask: "Wait a minute, what is picture G?"

"Graph g is a graph in graph theory. It refers to a graph composed of several different vertices and the edges connecting some of the vertices. Cousin, you don't understand, right? Didn't the training class say that? Then what do you do? Selected through the school?”

"I...I..." Shen Tiantian Ling was confused. Did I attend a fake training class?

In fact, similar concepts were taught in the training class, but she got confused just by memorizing the "induction method", "combination of numbers and shapes", "recursion method" and so on. As for the more advanced "graph theory" that follows, , "structural method" and the like are completely confusing.

In fact, the main reason is that Shen Tiantian's own mathematical talent is not very high. The training class is inherently cramming teaching. There are many knowledge points involved in the Mathematical Olympiad. How can Shen Tiantian, who has only attended the training class for half a year, master and memorize them all? ?

What's more, "graph theory" is also a difficult topic in Mathematical Olympiads. Teachers in ordinary training classes may not be able to fully understand it themselves, so how can they teach her in detail?

Seeing that his aggressive cousin was rendered speechless by the question, Qin Xiaoke secretly smiled, hugged his brother's arm, his eyes were bright, he was indeed the most powerful! Even Qin Yanghui showed his white teeth and secretly looked at her. Qin Ke gave a thumbs up.

A flash of surprise and admiration flashed in Shen Tieshan's eyes, but he still snorted habitually on his face: "The Mathematical Olympiad is not easy, don't be proud, if you have the ability, come back and show me the top three in the city competition."

Qin Ke smiled and said: "Top three in the city competition? Grandpa, you underestimate me. At least I am in the top three in the provincial competition."

"Don't talk nonsense. If you can really get into the top three in the provincial competition, I will bring the box of Maotai from my house to your house!"

"Okay, grandpa, it's a deal."

Here, Qin Ke habitually "exchanged fire" with his grandfather, but Shen Tiantian did not dare to provoke Qin Ke anymore. She was ashamed, angry, and restless. After a while, she found an excuse and ran away while Shen Tieshan was in trouble. , didn’t even stay for dinner.

Qin Xiaoke also escaped smoothly, and her grandfather did not use her midterm exam results as an excuse. For this reason, she even ate two more bowls of rice tonight to celebrate.

His father, Qin Yanghui, was heartlessly making noise with him. He took the opportunity to secretly drink a few bottles of beer, and even hugged Qin Ke. He laughed and said, "It's better that my Qin Ke is here, so I don't have to be criticized anymore." , you can also see the old man being beaten back, so refreshing! Come on, Qin Ke, have a cigarette!"

"Old Qin, I'm still a high school student. Can you have some awareness of being a father? I'm warning you, it's okay to do this to me. If my little sister is led astray by you, see how I deal with you!"

"Qiu Yi, your son threatened me again... wu wu wu..."

Shen Qiuyi looked at the lively scene at home, pursed her lips and chuckled, and suddenly asked Qin Ke: "Xiao Ke, have you started falling in love recently? Tell your mother quickly!"

Seeing the expectation on his mother's face, Qin Ke said angrily: "Answer for the ten thousandth time, no! I'm concentrating on studying, not in love! Mom, don't read those love novels and TV series all day long, they are all lies. How can human love be so beautiful?"

My mother is good at everything, but she really likes to read all kinds of romance novels and loves to fantasize. Other parents guard against early love like a scourge, but my mother wants him to have a girlfriend since kindergarten.

Qin Yanghui also encouraged: "Qin Ke, are you seventeen years old this year? It will be too late if you don't fall in love early. How can you grow up if you don't experience an all-consuming early love?"

Oh, and there is also this father who is afraid that the world will not be in chaos.

"Fuck you, old Qin, can you stop being so superficial? The news has said that now a new era is calling, youth needs to struggle, and the country's prosperity needs the hard work of the young people of our generation to build it. I am holding back a moment. We must work hard to live up to the mission of the times, live up to the expectations of the people, study hard to achieve the great rejuvenation of the nation, and better contribute to the realization of the second centenary goal in the future. What a fart in love!"

"Brother, didn't you say when you were a child that your goal was to become a god of learning and conquer the stars and the sea with knowledge? Why did you change it recently?"

"Xiao Ke, please don't tear me down! And, Xiao Ke, you can't listen to your parents' nonsense, about students falling in love early and so on, and you can't fall in love until you finish college!"

"Okay, brother, Xiaoke doesn't want to fall in love. I just want to rely on my brother for the rest of my life. I don't have to go to work and worry about life. I just stay at home to eat, drink and have fun. What a comfortable life.

ah!"

Qin Ke: "..."

Looking at this unreliable family, Qin Ke felt that it was a miracle that he could grow up to be such an upright, kind-hearted, morally upright, humble, courteous, well-loved, and outstanding scholar.
