Transmigrating Into The Heartthrob's Cannon Fodder Childhood Friend

Police station, communication room.

The policeman and Song Yu looked at each other with big eyes.

Holding a pen, the policeman smiled half-smile: "Why is it you again?"

Song Yu replied slowly: "Probably because I have a strong sense of responsibility by nature, and I like to call the police when encountering unfair things."

The policeman laughed: "No, what I'm asking is why you are always the one who gets beaten up by the group."

Song Yu: "..."

Xie Sui laughed beside him.

The gangsters were actually more injured than they were, but the group of red hairs had already been recorded in the police station, and they had countless criminal records.The police counted them as self-defense, and simply recorded them before letting them go.Originally, he was going to contact his parents, but Song Yu took the initiative to talk about the situation of Xie Sui's family, and his words were emotional and reasonable, so he canceled this link.

It was the same police station, and the same small clinic.

There are several people in the clinic, and the lights are bright.

The male doctor in the clinic still has an impression of them.

Doctor: "Last time it was a leg injury, this time it was a hand injury. You used real knives in any fight. Young man, you are wild."

Xie Sui sat on the chair, eyes slightly bent, smiled and said modestly: "It's okay."

The doctor was so angry that he almost broke the pen when he scratched on the paper: "I said you are wild and you are proud of it? You are showing off your prestige outside, have you ever thought about how worried your family is, at a young age Just let me study in peace, and if you insist on hanging out with that group of social youths who are not doing their jobs properly, if something happens, it will be your parents who are sad."

Song Yu held his mints in his mouth and spoke for Xie Sui: "Uncle, you misunderstood, you can't just look at the surface."

The doctor gave him a white look: "I haven't trained you yet, you kid is his friend, so you just watch him fight there? Don't you persuade him?"

Song Yu choked, his face a little embarrassed, scratching his head: "We are not talking about the same thing."

The doctor put the medicine in a bag and sneered: "Success. Don't look at the surface, are you fighting the scars left by aliens? Aliens also use such down-to-earth cold weapons?"

Song Yu: "..."

The TV hanging on the wall is playing Ultraman Tiga.The doctor's two-year-old son heard this, clapped his hands and turned his head, his big clear eyes curled up, and he laughed childishly, "Crooked Star Silver."

Xie Sui paid the money and took the medicine, "Thank you."

The doctor hates iron but not steel: "My son will grow up in the future. If you hurt yourself all day long like you, I will break his legs first."

Song Yu chewed the candy and yelled: "I said you can't look at the surface, what's the matter with you, uncle. My friend was injured by Chu Bao Anliang. He just fought against Street Bully with one enemy and one hundred. He defended all the north, south, north and south of Lianyun Street. The personal safety and property safety of primary school and high school students. These injuries are the scars of heroes."

doctor:"……"

The child sitting on the chair was drooling and clapped his hands: "Hero."

Song Yu laughed, "Hey kid, you're so smart, let me say it again."

The kid who was praised smiled very sweetly, and said in a childish voice, "Brother, hero."

The doctor saw that he was still teaching his own children badly, and was so angry that he took a feather duster to drive them away: "Go, go, fight street bullies bravely, I think you are the biggest bully in Lianyun Street."

"Pfft hahaha."

Song Yu, who was promoted to Street Fighter, laughed so hard that he dragged Xie Sui out.

A few moths gathered on a street lamp outside the clinic, and on a quiet summer night, small bugs could be heard humming in the bushes.

It was very late now, Song Yu stood under the streetlight, called Uncle Ma, and asked him to pick him up at the old place.

After hanging up the phone, Song Yu turned to Xie Sui and said, "I won't come here very often in the future. I'll see you at the beginning of summer vacation."

Those gangsters have criminal records, this time they will probably stay in the police station for several days, Xie Sui should be safe in July and August.

Solved the most dangerous thing he could encounter on summer vacation.

Song Yu felt that there was no need to run here anymore.

Xie Sui's breath still smelled of mint.

He couldn't help but wonder how much Song Yu liked Mint.

She retracted her fingers and smiled: "Well, see you at the beginning of school."

Song Yu stared at him, thinking of the young man who fought fiercely in the deep alley, he was speechless for a while.

He felt that he didn't understand Xie Sui again for a moment, but it seemed that he had never really understood it.

Get in the car, leave the remote residential area, and go to the center of the bustling city.

The neon lights were shining brightly, shining on Song Yu's thoughtful face.

Uncle Ma asked: "The young master still came to find your friend who hit it off right away?"

Song Yu came back to his senses: "Yes."

Uncle Ma said: "You run around every day, and the old lady is suspicious. I think if you come a few more times, she will meet your classmate."

Song Yu laughed: "Not coming, not coming."

In fact, it's okay to let Grandma Meng see Xie Sui.

It's just that he promised 008 not to appear next to Xie Sui as the third young master of the Song family, and he planned to make up the identity of "a poor distant relative of the Meng family" in the future. It would be easy to reveal his secrets when he met Grandma Meng.

Song Yu's QQ added very few people. He was lying on the bed playing with his mobile phone, looking at Jun Jun's dark profile picture, feeling a little itchy for no reason, and wanted to post something.

But today, I racked my brains to make a bad review, and ran a street in the middle of the night.Tired of mental and physical exertion.

I don't know when I fell asleep.

When I woke up the next day, it was already nine o'clock in the morning.

Going downstairs for breakfast, Song Yu was bombarded by Ma Xiaoding indiscriminately.

[Sadako never forgets the well digger: Hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaha]

[Zhenzi does not forget the well digger: Brother Yu, is it you who made a bad review? I went to eat at his place on purpose today. Seeing Zhu Zhixing's mother's face turned pale, I was probably going to die of anger. 】

[Sadako never forgets the well digger: Hahahahahahahaha, you are so talented, I also asked my younger brothers to follow your steps, and went to brush up several posts.Fuck this vicious woman to death! 】

Song Yu was already too lazy to care about Zhu Zhixing's affairs, thinking of Grandma Meng's expectant eyes and the stack of papers on the table, he suddenly had a headache.

He sipped his milk and sent a message to Ma Xiaoding.

[Your husband Brother Yu: How are your grades? 】

[Sadako does not forget the well digger:? ? ? 】

[Sadako doesn't forget the well digger: Why did you ask this, it's okay... right? 】

If you can get into Jingcheng No. [-] Middle School, your grades are not bad.

Song Yu hooked his lower lip and started typing.

[Your husband Brother Yu: Good grades in junior high school are not necessarily good grades in high school. Don't think that you can relax this summer vacation after the high school entrance examination is over. Others are now frantically enrolling in cram schools.No. [-] Middle School is under a lot of competition pressure, and people jump off buildings every year. It is luck that they are not seized by the government.You can't lose at the starting line in the first year of high school. 】

Ma Xiaoding was stunned by his father's speech.

[Zhenzi does not forget the well digger: ...Brother Yu, what do you want to say. 】

Song Yu had already returned to the room, pulled out the chair, sat at the table, and looked at the mountain of papers.

[Your husband Brother Yu: Come here, I'll share some knowledge with you.Good brother, let's do papers together. 】

【Sadako never forgets the well digger: ...】

Let's not be a good brother, okay?

Distributing half of the paper to Ma Xiaoding made Song Yu feel much more at ease.

Grandma Meng gave him a lot of information. During the transition period, many of them were consolidated and reviewed in junior high school, and then infiltrated high school knowledge points bit by bit.There are even the original questions of the college entrance examination, just to let him have a grasp of the difficulty.

Except for the first paper, Song Yu wrote it completely unprepared, and gradually found a little feeling later.

It is very difficult to pull a paper at the bottom of the book, so it is not required to do it.Song Yuxian turned to the last question and was stunned.

A very classic function problem, e raised to the xth power and e multiplied by x.

He didn't plan to try the final question yet, but he vaguely felt familiar, and even a very vague concept appeared in his head.Biting the pen and thinking for a long time, I finally remembered it.

Isn't this a typical example of Lagrange's median value theorem!

He will still remember this question, and it is probably because the name of this theorem that the high school teacher mentioned is too weird when expanding the thinking of solving the problem.

The theorems given on Baidu are very puzzling if not combined with specific examples.Song Yu just wanted to finish his first conversation with Xie Sui.

So I took a picture of this question and sent him a message.

Because of the shame of A66 in the first blood, he bit his pen and thought about it.

Pretentiously.

【Do you know what is the Lagrangian mean value theorem? 】

Xie Sui was leaning on the bed, typing on the computer with his fingers, hacking into Linshui's intranet and calling out the monitoring records.

After finishing everything, he went to grab the water glass next to him, and saw the bright message on the phone.

[Song Yu: Do you know what is the Lagrange mean value theorem? 】

Xie Sui: "..."

He should be glad he didn't drink water.

Xie Sui's grades have always been outstanding when he was a student, his personality is withdrawn and indifferent, and he has never had any contact with normal classmates.

Therefore, I can't understand the brain circuit of Song Yu, a scumbag who relies on perseverance to solve problems.

——You even rely on numbers for permutations and combinations, why ask Lagrange?

Of course, Xie Sui didn't say anything about this self-esteem problem.Because he could see that Song Yu's enthusiasm for learning seemed to be quite high, and he didn't want to hit him.

Xie Sui took out a pen and a piece of paper, taking care of Song Yu's knowledge reserve, wrote out the standard solution to the question in detail, and then took a photo and sent it over.

【Xie Sui: [Picture]】

【Xie Sui: You don't need that. 】

Song Yu waited for a long time, and just waited for such a sentence, accompanied by a photo with clear thoughts and beautiful handwriting.

Even simpler and understandable than the answer.

Niubi is worthy of being the protagonist, the proud son of heaven.

But Song Yu would persevere and continue to ask when he was stuck at the tip of his head.

[Song Yu: Then how to use that? 】

By the way, I sent a few emoticons.

【[Scratching head question mark]】

【[ballballyou]】

Xie Sui paused with his fingers on the little soybean scratching his head, as if he saw Song Yu's troubled appearance on the phone, his expression was a little lost, and then his thin lips curled up.

[Xie Sui: So you want to know? 】

[Song Yu: That's right. 】

【Xie Sui: Just cross out the large paragraph from the third line to the fifth line, and change it to "It can be known from the Lagrange mean value theorem". 】

"???"

After Song Yu did what he said, he sighed like a scumbag.

[Song Yu: There is a number that makes them equal within the interval. 】

Xie Sui didn't even want to tell him that it was a theorem. After thinking about it, his eyelashes drooped, and his dark pupils smiled wickedly.

[Xie Sui: Didn't I give you a range?You can substitute them one by one, and you will always find that number]

Song Yu: "..."

Song Yu: "..."

Your fucking range is infinite!

Why did he always feel that Xie Sui was laughing at him.
