In addition to the clothes store, Liu Yichen breathed a sigh of relief.

Damn!

Kill yourself and never come here again next time. Isn’t this a scam? Look at the eyes of those women looking at me. The glowing, interesting and curious look made Liu Yichen want to find a hole to crawl in. It’s so embarrassing.

Some women even gave him a glamorous look from time to time and discharged her with their eyes. They died young, and they were not interested in these women at all.

After shopping for clothes, it was already 9:30 in the evening. Liu Yichen sighed secretly. This girl is a natural expert in shopping for clothes.

The two walked back to school, chatting while walking.

Feng Lin laughed from time to time, obviously in a good mood, while Liu Yichen was in a good mood in addition to being embarrassed in the women's clothing store.

The two talked and laughed, chatting about this and that, the spring breeze was whispering slightly, and it was fascinating. It really made people intoxicated. The spring breeze was not intoxicating, and people were drunk by themselves.

The lights on the road are dim and there are very few vehicles. Most of the students are walking here. Although love is forbidden in schools, high school students are over 16 years old and are in a vague curiosity about love. In addition, youth idol dramas are now prevalent, which naturally stimulates the yearning for love and always falls in love.

Therefore, high school campus love is not a rare thing. No. 1 Middle School is relatively rare. This situation in No. 2 Middle School is quite common, which makes Lao Liu worry that his daughter is dating in school, so he no longer lets Liu Tingting live on the school, but returns home to live, and time is tightly squeezing.

"Liu Yichen, are we in love now? Am I your girlfriend now?" Feng Lin suddenly asked, "I am your girlfriend now, right!"

Liu Yichen was stunned.

What do you mean by this? Isn’t it better for two people to be friends? Why don’t you mention which pot to open?

How do you answer this?

Now I am devoted to studying, so where can I have time and mind to fall in love? Now I am moving towards the goal of a top student, and I am determined to become a top student. There is also a broken system that is staring at me from time to time, so as not to let myself slack off at all.

I want to say that I don’t want to fall in love.

But, it’s true that he is a straight man, but he doesn’t know nothing. The soul is the soul of an uncle in his 30s. If he knows that Feng Lin will probably die of sadness, the two will have a gap from now on, and it is unlikely that they will become friends again.

To be honest, for Feng Lin, Liu Yichen has a pretty good sense and a good personality. Although his family is rich, he does not have the high profile and show-off of the rich second generation, and he also studies very seriously.

The point is that Feng Lin is very beautiful. Although she has a little baby fat on her face, she can still see the beauty. If she put on makeup and smiles, it should be no problem to compete for the school beauty.

"This... Feng Lin, we are still high school students and cannot fall in love." Liu Yichen hesitated for a moment and organized a speech: "My family's adults strictly require me not to fall in love in high school. If you want to fall in love, you have to fall in love before falling in love."

"Our task is to study hard and try to get into a good university!" Liu Yichen said: "Now you are my only friend in school. If you still like me in college, let's try to fall in love."

As he said that, Liu Yichen had a prank and said jokingly: "I think you are your best friend, but you want to fuck me and have a baby for me."

Feng Lin was still nervous, shy, and sad just now. Now when he heard Liu Yichen's joke, Feng Lin was furious: "Liu Yichen, go and die~~"

As he said he wanted to hit Liu Yichen, Liu Yichen carried his clothes and shoes in both hands, and ran away when he saw this, chasing and running.

On campus, after the fight, the two of them walked side by side, the lights were dim, and there were very few people, only the chirping of crickets. Neither of them spoke at this time, enjoying this moment of tranquility.

Suddenly, Feng Lin hugged Liu Yichen, which scared Liu Yichen so much that he almost put the things on his hand down and dropped them on the ground.

Why did this little girl become so bold all of a sudden? This would be bad if she was seen in school.

‘Ding Dong~’ Feng Lin put his toes on his toes and kissed them.

Soft and soft, Liu Yichen's whole body was as if he was electrocuted, and his beauty could not be described in words.

After a long time, the lips parted, and the two of them were breathing a little rapid. Feng Lin avoided his eyes, lowered her head, and her little face turned slightly red...

Liu Yichen was stunned.

My first kiss...is gone!?

Damn, this little girl is too brave. She always attacks and kisses him. This was the case last year, and this time it is still like this.

This is a sure thing for me... won't you refuse anyone?

Liu Yichen was a little depressed, and he really wouldn't refuse... and by the way, the kiss was quite wonderful and intoxicating.

"From now on, you are my own... If you want to find a girlfriend, you can only find me. If you dare to find someone else, I will bite you~~" Feng Lin's slightly red face and thin body said unparalleled words.

What a guy, I thought it was a pure little girl next door, but I didn’t expect that she would be a domineering queen.

She actually misunderstood her eyes, and Feng Lin actually has the potential to be a queen.

When they entered the dormitory building, the two separated. Most of the students in the dormitory building went home on May Day holiday, and only a few of them were left.

When he returned to the dormitory, Liu Yichen put his clothes and shoes in his arms, and he was still a little dizzy. He did not expect that the girl now was so bold. He was a big man, but was chased by a woman.

He was really shocked!

"But...it seems pretty good!" Liu Yichen muttered, and Feng Lin's appearance couldn't help but appear in his mind. His face was full of the beauty of a girl.

Well, Liu Yichen admits that he seems to like being a stranger.

......

On the other side, Feng Lin returned to the dormitory with her clothes and shoes, and immediately locked the dormitory door. She seemed to have lost strength all of a sudden. She felt that her face must be very good, just like a fire was burning. Her heart was beating quickly. She could hear her heartbeat, and her heart seemed to be about to jump out.

Her mind was filled with Liu Yichen's figure, holding her cheeks with both hands. The more she thought about it, the more she became shy she became, and the more she felt ashamed she felt.

"Oh~~Feng Lin, how can you do this?"

"How can you be so proactive, as a girl?"

"Will Liu Yichen feel disgusted with me? Will he stop being friends with me?"

"He said I was his only friend~Didn't that believing that I am his girlfriend?"

“…”

That night, Feng Lin was sleepless, like a little girl who fell in love, turning around and unable to sleep. Various fantasies appeared in her mind, fantasizing that the two of them watched movies together, fantasizing that the two entered college together, fantasizing that... she walked into the marriage hall sweetly and happily in a beautiful wedding dress.

The German poet Goethe once said: Which man is not in love with, which girl is not in love with?

This is true!

......

On the other hand, Liu Yichen took a cold shower to calm his body so that his blood would be like boiling.

After calming down, Liu Yichen was reading a book in the dormitory. He was the only one in the dormitory now, and all three roommates had gone back.

One advantage of May Day holiday is that the dormitory will not turn off the lights. And the dormitory building also seems much quieter.

He has now learned that sequences are mainly used to solve the general formula of the sequence, including the conversion method, the feature root method, the fixed point method and iterative method, the mathematical induction method and the recursive method.

Although its importance is not as important as functions, plane geometry and three-dimensional geometry, it is also a relatively important knowledge point in high school, and it involves a lot of mathematical thinking, such as the transmutation method. This is a very common and commonly used mathematical thinking in high school. Complex mathematical problems are carried out in simple ways.

The conversion method does not exist only for a quadratic equation. In fact, it can transform high orders into low orders, fractions into integrals, irrational formulas into rational forms, and transcendent formulas into algebraic formulas. It has been widely used in the study of equations, inequality, functions, sequences, triangles and other problems.

The methods of changing the element include local exchange, triangular exchange, mean exchange, etc. The types of exchange include equal parameter exchange, non-equal exchange.

Liu Yichen has now faintly touched on the knowledge points to understand its thinking more deeply, rather than just staying on the methods and tools.

It vaguely understands why mathematics is so great and why mathematics is so important!

Why do those great mathematicians leave their names in history and keep them famous throughout the ages, allowing the world to remember them forever!

He learned mathematical knowledge, which was the wisdom left by mathematicians. It is better to say that learning mathematical knowledge is to learn mathematical wisdom, learn the wisdom of these mathematicians, and use theorems and formulas to talk to those mathematicians through time and space.

Although he is very small, he is in the midst of rapid growth. Sooner or later, he can thrive into a big tree. The mathematical wisdom left by these predecessors is the nutrients and water for his thriving growth.

What kind of big tree he can thrive depends on how much water and nutrients he can absorb.

"Sure enough, Newton was right. Only by standing on the shoulders of a giant could he stand high and look far!" Liu Yichen muttered to himself.

Everyone's impression of Newton is often that he is a great physicist. The only one who can compete with him is looking at the entire history of humanity. Einstein Newton is like a physical giant, standing in the history of physics, looking down on the world and the latecomers.

In fact, this impression is somewhat biased, because Newton's mathematical achievements are also amazing. For example, he is the founder of calculus or one of the founders. He proved the generalized binomial theorem, proposed the "Newton's method" to approach the zero point of the function, and made outstanding contributions to the research of power-level functions.

The research results of generalized binomial theorem, Newtonian identity, Newtonian method, vertical curve classification, finite difference force, divan graph equation, power-level functions, etc. are Newton's great contribution to mathematics and the treasure left to the world.
