When the time comes, the group takes the high-speed train to the capital, spanning most of the provinces across the country between the starting point and the destination. The road is still long, and you can enjoy the scenery outside the window, pick up your mobile phone to play games, sleep on your tummy, or simply pick up your math problem to think about it.

After getting on the bus, Ouyang Zhe sat in his seat, suddenly thought of something, and said with a smile: "I suddenly thought of a math problem. How far do you think of Yangcheng and the capital?"

"Can you know this problem by looking at the map?"

"I definitely can't check the map. What's the point of looking for the map? Actually, I thought about it and could calculate it by knowing the radius of the earth, the longitude and longitude of the capital and Yangcheng."

"The idea is correct. The earth is a spherical surface, so you have to consider the distance of the spherical surface. Just be simple. First consider the same longitude, then consider the same latitude, calculate two right-angle edges, and use the Pythagorean theorem on the spherical surface to calculate it."

"Okay, I'll check the radius of the earth online and see who calculates it first."

...

The five people were discussing, and they were all top mathematics masters in their respective schools, and they soon calculated the spherical distance between Yangcheng and the capital.

After Ouyang Zhe calculated the answer, he couldn't help looking at Li Xuan.

Li Xuan sat in his seat and read a book, without communicating with others, nor did he count this question.

In fact, the question raised by Ouyang Zhe was too simple. Li Xuan’s current computing ability is too strong. The formula was calculated from the cosine theorem, so he did not participate.

The radius r of the earth and the latitude and longitude of the two places (a1,b1)(a2,b2), the spherical distance is rxarc(sina1sina2+cosa1cosa2cos(b1-b2).

Of course, Li Xuan was not very interested in this kind of communication.

Li Xuan sat in his seat and was not idle. He was holding the algebra theory and became a little bookworm. He chewed happily, and it was very quiet.

Seeing Li Xuan like this, everyone else was stunned and had no intention of playing. They picked up the books and started reading them one after another. It didn't matter to Zhou Lele, but he picked up his mobile phone and started playing games.

At this time, Ouyang Zhe noticed that the content in Li Xuan's book was familiar, and said in surprise: "Li Xuan, are you reading Algebraic theory?"

"Yeah, just saw it."

"Li Xuan, this book is very good. The explanation of number theory is very systematic. You can understand it even if you have no foundation. I have read it for half a month and have benefited a lot."

Li Xuan was stunned for a moment. Could it be that his brain is so good? In fact, it only took him two days and it took him less than half a month to read the book. Of course, he understood it thoroughly, not just a quick look. Now he read it again, and he has a new experience.

Of course, some of the problems after class were very troubled. In the mathematics competition, it was too common to understand the knowledge and do the questions. Because the style of the questions has changed, it is very challenging to have skills. Number theory pays special attention to skills and is more obvious.

Li Xuan thinks he is not smart enough?

To be honest, Li Xuan enjoyed the pleasure of becoming smarter. Now his schoolbag is still hidden in his online purchases and silver-white wigs.

When shopping online, he not only bought the books that Lin Xuerui asked for, but also bought a silver-white wig. The quality is very good, imported high-temperature silk, which is smooth and soft to touch.

Li Xuan swore that he had bought it by accident.

When Ouyang Zhe saw that Li Xuan was focused on reading, he did not continue to disturb him.

After a while, Li Xuan looked at the book that might be the most difficult question in the book, but found that he still had no idea and was a little annoyed.

Grass!

I knew it would be like this.

He started thinking about this question last night, but he still doesn't know how to do it. His brain is still not smart enough?

He really wants to be smarter.

Only women's clothing can become stronger?

Forget about women's clothing, although I found that it didn't seem to be anything.

Wear a wig?

So the question is, is wearing a wig considered women's clothing?

The system told him that wearing wigs can get appreciation value, but Li Xuan thinks that wigs are not women's clothing, and women's clothing requires clothing, so the literal meaning is different.

After thinking about it, he suddenly took out a silver-white wig from his schoolbag. He hesitated for a moment, glanced at the surroundings, gritted his teeth, and put it on his head.

For the scientific starry sea, he decided to take his time.

Not women's clothing.

Just a wig.

He recited it silently three times.

This way there will be no psychological pressure.

Li Xuan's long hair looks really beautiful. Although she has no makeup, her facial features are very delicate and her skin is good, and she becomes beautiful in an instant. The air bangs and silver wigs make Li Xuan's facial features look very girlish, just like a beautiful girl walking out of an anime.

Because Li Xuan is talented, he can meet the minimum requirements of the system by wearing a wig.

Ouyang Zhe turned around and saw:=-=

Cao Song: “….”

Zhou Lele: “…o.o”

Li Xuan pretended that he hadn't seen the other surprised and stunned eyes, and just shame. In order to become stronger, it's nothing to wear a wig.

System prompt: [Get five appreciation values].

Li Xuan was speechless. He didn't say anything about this group of people, but he was still very honest in his heart. He also thought that he was beautiful when wearing a wig.

He doesn't dare to do this at school for the time being, so wearing a wig here is not as stressful as he has just met him anyway.

Li Xuan's group was connected to each other, and he happened to be sitting together. Zhou Lele's position was right in front of Li Xuan. At this time, he stood up and turned around and suddenly saw Li Xuan's long hair and bowed his head. He was stunned.

His heart beats wrongly and his breathing is a little rapid.

The people who walked through the aisle also saw Li Xuan, and their eyes lingered on Li Xuan for a while, were inexplicably surprised.

The system prompted to gain appreciation value.

Li Xuan couldn't care what the people around him thought. He was a little nervous when wearing a wig for the first time, but fortunately, his psychological quality was OK and he didn't blush.

But Li Xuan also found a problem. He was so shameless, but the appreciation he got was still pitifully small.

This is a bit too much.

Li Xuan thought for a while, then took out his cell phone, didn't care about other people's gazes, and prepared to record a short video and post it to the fun.

In short video apps like Douyin, it is very popular to have good looks. Of course, you have to be cute to be popular only when you record videos. Li Xuan thought that he would wear a wig and he would be cute no matter how he moves, nothing.

As a straight man, don’t know too much about men’s psychology. Isn’t it just like cuteness? The so-called men are just a group of stupid visual creatures.

He picked up his phone and was about to start recording. He looked at the camera quietly without smiling. The front camera of the phone captured his appearance and then presented it on the screen of the phone through the fun and beauty function.

That's what his hair looks like when he grows?

Li Xuan was stunned when he looked at it. He was so beautiful that he had been traveling through time for so long, and every time he saw this face, he still felt unreal.

It is as graceful as a floating cloud, as if it is astonished as a dragon. The face is as creamy as a varnish, and the eyes are as varnished.

Li Xuan was a little confused and found that long hair did have plastic surgery effects. His appearance was very suitable for long hair. If his girlfriend looked like this, he would be happy to accept it. He suddenly wanted to kiss the little beauty on the screen of his phone and pouted slightly into the air, similar to kissing.

This action was recorded.

Ouyang Zhe: “…”

Cao Song: "????"

Zhou Lele: "!!!"

After recording this way, Li Xuan also found something was wrong and felt a little scared. What did he do just now?

But if you think about it carefully, this kind of action is normal. Isn’t it just a pout? Don’t a boy pout?

Not deliberately cute.

What's wrong with him kissing himself!

It is normal to comfort yourself.

The road to a super academic master is probably destined to be full of ups and downs.

The system prompts: "Critical strike, congratulations to the host for harvesting 50 appreciation points."

Li Xuan was surprised and suspicious. Is there any such operation of critical strike? The appreciation value has increased ten times?

Not sure what to say, Li Xuan glanced at the classmate beside him. The group of people was still looking at him for a moment. The critical strike prompted by the system told Li Xuan that the group of people had rich thoughts in their hearts.

Seeing Li Xuan's gaze, this group of people dared not to have Li Xuan anymore, lowered their heads, looked at their noses and their hearts.

They don't know what their mental activities are.

Li Xuan ignored it, rolled his eyes, communicated with the system, "Enough to replenish my brain."

Then, upload the short video to Douyin and wait for official review. This is his Douyin number’s first video.

After doing everything, Li Xuan took off his wig and breathed a sigh of relief.

Li Xuan turned his head quietly and looked out the window, as if nothing had happened, like a lonely outsider, but gradually fell into thinking again.

The green mountains and clear waters outside the glass window kept retreating.

He suddenly remembered his sister again.

On his lunar birthday, Mu Xi told him a happy birthday. At that time, she still remembered her silent appearance. Because Li Xuan did not tell Ling Chu, Ling Chu didn't know his lunar birthday.

If you think about it carefully, his approach was indeed a bit too much and he didn't even say thank you.

This time I went to the winter camp and asked the school for a long vacation. When I came back from the capital, I happened to see her.

Li Xuan thought he would rather say thank you.
