But he calls me baby [campus]

================

This Saturday, there was no exam in the competition class, Qi Sibai just finished washing at [-]:[-], sat at the dining table, and ate bread slowly.

Grandma Qi took out the boiled eggs from the pot, rinsed them with cold water, and served them to the table.

"Is it going to be late again?" Grandma Qi glanced at the wall clock on the wall of the living room, "Take the fresh milk, drink it between classes?"

Qi Sibai unsealed two bottles of fresh milk, "It's all right, don't worry."

Grandma Qi took it, sipped it, and suddenly asked: "Speaking of which, you and Xiaosheng live in the same building, did you meet each other when you went to school in the morning?"

Qi Sibai said of course not.

Even if you live in the same unit, there are different elevators.What's more, he and Jiang Yusheng are in different units, and the gates are not the same.

"Oh, I think so." Grandma Qi nodded, and said clearly: "I went to the vegetable market yesterday morning and met Grandma Yanbin. I heard from her that Xiaosheng was always the first in the original school."

As she said that, Grandma Qi joked: "How many good students are there like you who go to school?"

Qi Sibai carefully peeled the eggshells while arguing: "The closer you live, the later you will arrive. Grandma, this is an objective law. Maybe after a while, Jiang Yuesheng will be later than me."

"Crooked ways," Grandma Qi laughed: "Then, you two will be late together? Don't get mad at you, Mr. Chen."

Qi Sibai imagined the scene for a while, and inexplicably felt that Mr. Chen would not get angry with a good student like Jiang Yusheng, and he could take the opportunity to gain some of Jiang Yusheng's glory.He was about to speak, but suddenly stopped.

...almost misled by grandma.If he was going to be late, of course he would ride away, and he wouldn't get together with Jiang Yuesheng.

At [-]:[-], Qi Sibai went out with his schoolbag on his back, walked through the branch road leading to the unit building, and entered the main road of the community.

Before taking two steps, he saw a familiar figure tens of meters ahead.

The boy is tall and tall, with straight shoulders.The loose black T can't cover the broad shoulder line, and the ordinary school pants that half cover the sneakers still line his slender legs.With his left hand in his trouser pocket and his right hand carrying a school uniform jacket, he walked leisurely.

The demeanor was so distinct that Qi Sibai recognized it at a glance as Jiang Yusheng.

This was the first time he met Jiang Yusheng on the way to school.

For someone else, Qi Sibai came to say hello in the morning.But this person happened to be Jiang Yuesheng who he just thought about yesterday to control the social distance reasonably.

Qi Sibai hesitated for a moment, glanced at the time, then slowed down, keeping a distance of nearly 50 meters from Jiang Yuesheng.

He originally thought that it was getting late, and Jiang Yusheng would walk faster anyway.

Unexpectedly, when passing by the stray cat nest in the garden of the community, Jiang Yusheng stopped for some reason. Immediately, three stray cats suddenly ran out of the bushes, and a Sanhua kitten even raised its front legs to rest on it. onto Jiang Yusheng's trousers.

Only then did Qi Sibai notice that Jiang Yusheng seemed to be holding a bag of food in his right hand.

Jiang Yusheng took a step back, trying to avoid the little greedy cat, but the kitten was still at the stage where it didn't know how to be afraid of people, Pidiandian rushed forward again, and with a pounce, both feet hugged Jiang Yusheng's calf .

In an instant, there were streaks of gray on the black pants.

The other two big cats also circled Jiang Yuesheng half a circle, raising their heads and meowing.

Looking at Jiang Yusheng's frozen expression from a distance, Qi Sibai laughed a little.

After a while, Jiang Yusheng bent the corners of his lips as if helplessly, untied the plastic bag in his hand, and poured the food in the bag into a few iron fists next to the cat's litter.

The kitten spread its paws and ran to the bowl to grab food from the big cat.Jiang Yusheng squatted down and raised his hand, as if to touch the kitten's head, but in the end he only stretched out his index finger and poked its furry forehead buried in the bowl.

During the movement, Jiang Yusheng tilted his head to the right and rear.

Qi Sibai suddenly hid behind a crabapple tree with dense branches and leaves.

Soon, Jiang Yusheng got up and continued to walk towards the gate of the community.

Qi Sibai heaved a sigh of relief as if guilty of guilt, raised his wrist and looked at his watch, only to feel his blood pressure go up.

It's 46:[-], why is Jiang Yusheng still acting unhurried?

A short distance away, he and Jiang Yusheng left the gate of the community and went around two bends.After that, Jiang Yusheng stood at the intersection, waiting for the red light.The school gate is just across the road across the street.

Qi Sibai slowed down, hesitating.

Suddenly someone patted his right shoulder. He turned his head and saw that it was a boy from the Huajing class, named Xu Ta, who lived in the neighborhood next door.The two would meet each other on the way to school from time to time.

"Qi Shen, are you so late?" Xu Ta smiled and wanted to move forward.

Qi Sibai had no choice but to follow along, explaining: "There is no exam this morning, Mr. Chen usually asks everyone to correct the papers first, so don't worry."

Xu Ta weighed the heavy schoolbag on his shoulder, "Ah yes, I heard that you are number one."

The two walked side by side to the zebra crossing, exactly one person away from Jiang Yuesheng.

Jiang Yu heard the sound and looked sideways.

Only then did Xu Ta see Jiang Yusheng, and tentatively said, "Jiangshen is good."Qi Sibai paused when he was moving towards Xu Ta, and smiled at Jiang Yue, as if greeting him normally.

Jiang Yusheng looked at Qi Sibai, smiled inexplicably, and then nodded towards Xu Ta indifferently.

Seeing that the atmosphere was a bit cold, Xu Ta had no choice but to try to find a topic: "Qi Shen, many people in Moments were talking about your basketball team's friendly match yesterday."

As he said that, he leaned over to Qi Sibai, "I saw several short videos of you, so handsome."

Qi Sibai raised his eyebrows with a smile.

"Mun Shen also reposted a post in the sand sculpture emoji exchange group in the grade yesterday." Xu Ta smiled at them, and said in a joking tone: "Discuss what your relationship is now."

Qi Sibai subconsciously glanced at Jiang Yusheng, seeing that Jiang Yusheng's expression was still calm, he bumped Xu Ta's shoulder, and said with a smile: "It's all jokes on the post bar, Jiang Shen and I have known each other for a week, what could it be?" relation."

Xu Ta was a little nervous when he asked the question just now, but now he also smiled, "Yeah, there is always a riot on the post bar. According to them, you and I can build a building."

Qi Sibai shook his head helplessly.

Jiang Yusheng glanced at them indifferently, and after a while, hummed.

Qi Sibai was stunned for a moment before he realized that Jiang Yue's "hmm" was in response to his "what could it be?"

The atmosphere became inexplicably cold again.

The red light goes out, and the villain on the green light begins to walk.

Xu Ta was afraid of embarrassment, so he had to drag Qi Sibai to chat on one topic and the other.The three of them crossed the road, and within a few steps, Jiang Yuesheng walked far ahead, leaving an indifferent back view for the two behind.

"I finally feel what is called a 'moving refrigerator'." Xu Ta finally stopped standing side by side with Jiang Yusheng, relaxed a little, and said suddenly: "I didn't say anything just now to offend Jiang Shen, how do I feel? He is not quite the same as the one seen in the photo yesterday..."

Qi Sibai asked: "What photo?"

Xu Ta smiled, "Haven't you seen the post that Mu Yangcheng reposted? A girl took a picture of Jiang Shen delivering water to you, and Jiang Shen's expression felt...very gentle? I don't know how to describe it. "

When Xu Ta said this, the orange sky of yesterday evening flashed across Qi Si's white mind.

The crowd was loud and the weather was hot.Next to the green rubber field, the boy standing in front of him has a mint-like coolness and a little familiar fragrance.It is completely different from the surroundings, making people feel the breath of ironing.

He lost his mind, and was called twice by Xu Ta, asking what's wrong.

Qi Sibai was stunned for a moment, and said nothing.

He was just wondering if something he said just now offended Jiang Yusheng.

But he didn't say anything just now.

Qi Sibai separated from Xu Ta on the first floor of the high school building. When he entered 307, he saw Jiang Yusheng already sitting on the seat reading a book.

Mr. Chen was writing on the blackboard when he turned around and saw Qi Sibai, and tapped on the blackboard, "What are you doing standing there, it's 59:[-], why don't you go back to your seat?"

The first and second quarters in the morning.In the first half of the class, Mr. Chen asked everyone to correct the papers by themselves. In the second half of the class, Mr. Chen started to answer each question one by one, and asked people to come to the stage to write their detailed practices, and then he would talk after finishing.

For the medium-difficulty questions, Mr. Chen just clicked casually.When it comes to difficult questions, I click and click, and I always hang people on the blackboard. I get stuck halfway through writing, and people in the seats under the stage find some loopholes.

At the end of the point, it was inevitable that Qi Sibai and Jiang Yusheng would sneak together to the blackboard to write the process.

Like Mu Yangcheng and Jing Yanbin who love to gossip, at first they watched the excitement and made strange noises, but gradually they became silent.

Because, the atmosphere in front of the blackboard is really weird.

Others came to the stage, wrote on the same blackboard, met each other while writing, or fought for the space with a smile, or simply discussed it on the spot.

But Qi Sibai and Jiang Yusheng didn't exchange a word the whole time.The handwriting of the two people, one is free and easy and indifferent, and the other is correct and cute, but the distance between the two of them seems to be thousands of miles in the process of writing, and the smell of unfamiliarity with each other is almost overwhelming.

Mr. Chen couldn't bear to read half of it, and said happily: "Qi Sibai, when did you become so refined, you had to squeeze into the small corner on the right to write? Who is the big space in the middle of the blackboard for?"

Hearing the words, Jiang Yu glanced sideways at Qi Sibai.

Qi Sibai's hand holding the chalk paused for a moment, and with an oh, the next line moved to the left by a number.

Old Chen: "..."

The two bosses in front of the blackboard finally finished writing their respective processes "unacquainted with each other". Mr. Chen squinted at Jiang Yuesheng's process, and said kindly, "God Jiang, tell me what you did?"

Jiang Yusheng put down the chalk and explained the process of writing line by line.

The elegant bird under the stage was silent, and Mr. Chen leaned against the table with his chin resting, as quiet as a sculpture.

There are generally two possibilities for this situation. One is that the question is too simple, and everyone is either too lazy to listen and is doing their own thing, or they are actually in a daze.The second possibility is that this question is too difficult, and the people listening under the podium didn't even have a sympathy, and they were in a blank state of "Who am I? Where am I? Has this god finished beeping?".

The class was silent for another two seconds.

Qi Sibai stood on the other side of the blackboard, watching the faint golden light coming in from the window lattice, outlining the profile of Jiang Yuesheng's profile deeply and smoothly.

The boy's demeanor was as cold and calm as ever.The fingers resting on the blackboard are bony and fair, with obvious joints and blue veins protruding from the back of the hand, clearly visible.What did not violate this temperament was his voice.

It is cold and indifferent, exactly the same as the sound of the wind passing through the treetops outside the window and the fluttering of sycamore leaves.

Qi Sibai was in a daze, and heard Chen Lao slowly say: "The formula in the penultimate line is..."

The fourth last row?

Jiang Yusheng did the same thing as him. Qi Sibai knew what Mr. Chen was asking, so he blurted out an explanation: "He has already set a1, a2 to ap as an arrangement that satisfies the meaning of the question. For each 1 to p Between k, k-1 and p are mutually prime, so this formula has a unique solution within 2, 3 to p-1, recorded as ak..."

As soon as Qi Si's vernacular words fell, he paused first.

There were a few whispers of sudden enlightenment from under the podium.

"Oh, oh! Yes, I forgot to set it before." Chen Lao moved his finger on his chin, and then he turned his eyes to Qi Sibai belatedly.

Why can't he figure out what tricks these two kids are playing recently?Didn't you just pretend that the well water does not violate the river water, why did you help to answer in the blink of an eye?

Jiang Yusheng paused with his fingers, hummed, and continued: "Next, we just need to prove that the aks are different from each other."
