Police station, communication room.
The police and Song Yu have big eyes on small eyes.
The policeman held a pen and smiled, "Why is it you again?"
Song Yu replied slowly: "Probably because I have a strong sense of responsibility, I like to call the police when I encounter unfair things."
The policeman was delighted: "No, what I'm asking is, why is it always you who is beaten by the group."
Song Yu: "..."
Xie Sui laughed beside him.
The gangsters were actually more seriously injured than them, but the red-haired group of people had a record in the police station and had numerous previous convictions. The police counted them as self-defense, only briefly recorded it, and let them go. Originally, he wanted to contact the parents, but Song Yu took the initiative to tell the situation of Xie Sui's family, and the words made sense, so he canceled this part.
It's the same police station and the same small clinic.
There are a few people in the clinic, and the lights are bright.
The male doctor in the clinic still had an impression of them.
Doctor: "Last time it was a leg injury, this time it was a hand injury, and it was a real knife to fight. Young man, you are wild."
Xie Sui sat on the chair with slightly curved eyes, smiled and said modestly, "It's okay."
The doctor was so angry that he almost broke the pen on the paper: "I said that you are wild and you are proud of yourself? You are showing off your prestige outside. Have you ever thought about how your family is worried? Just read me in peace, and you have to follow the group of social youths who are not doing their jobs properly. If something goes wrong, it is your parents who are sad."
Song Yu held his mint and spoke for Xie Sui: "Uncle, you have misunderstood. You can't just look at the surface."
The doctor rolled his eyes at him: "I haven't trained you yet. Your kid is his friend, so he's just watching you when he fights? Don't you persuade him?"
Song Yu choked with embarrassment on his face, scratching his head: "We're not talking about the same thing."
The doctor put the medicine into the bag and sneered: "Sure. 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 listened, clapped his hands and turned his head, his big clear eyes rolled up, and he laughed in a milky voice: "Crooked Star Silver."
Xie Sui paid the money and took the medicine, "Thank you."
The doctor hated that iron could not become steel: "My son will grow up in the future. If you hurt yourself like you all day long, I will break his leg first."
Song Yu chewed on the sugar and shouted: "I said you can't look at the surface, what's the matter with you, uncle. My friend was injured by Chuyu Anliang. He just fought against a hundred and fought Street Fighter bravely. He defended all the north, south, north, south, and north of Lianyun Street. The personal safety and property safety of elementary, middle and high school students. These injuries are the scars of heroes."
doctor:"… "
The child sitting in the chair drooled and clapped his hands: "Hero."
Song Yu was amused, "Hey little kid, so smart, say it again."
The child who was praised smiled especially sweetly, and said in a milky voice, "Brother, hero."
Seeing that he was still teaching his own children badly, the doctor was so angry that he used a feather duster to drive them away: "Walk around and fight Street Fighter bravely. I think you are the biggest bully on Lianyun Street."
"Pfft hahaha."
Song Yu, who was promoted to Street Fighter, couldn't laugh, and dragged Xie Sui out.
A few moths gathered on a street lamp outside the clinic, and on a quiet summer night, the whispers of small insects could be heard from the bushes.
It was very late now, Song Yu stood under the street lamp, 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. See you at the beginning of the summer vacation."
Those gangsters have previous convictions. This time, it is estimated that they will stay in the bureau for several days. Xie Sui should be safe in July and August.
Solved the most dangerous thing his summer vacation will encounter.
Song Yu felt that there was no need to run here anymore.
Xie Sui's breath still smelled of mint.
Can't help but wonder how much Song Yu likes mint.
He closed his fingers and smiled: "Well, see you at the beginning of school."
Song Yu stared at him, thinking of the boy who fought fiercely in the deep alley, and was at a loss for words.
He felt that he didn't understand Xie Sui for a moment, but it seemed that he never really understood.
Get in the car, leave the remote residential area, and walk towards the bustling urban center.
The neon lights glowed brightly, shining on Song Yu's thoughtful face.
Uncle Ma asked, "Young master, did you still come to find your friend who hit it off?"
Song Yu recovered: "Yes."
Uncle Ma said: "You are running 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: "I won't come, I won't come anymore."
In fact, it's nothing to let Grandma Meng see Xie Sui.
It's just that he promised that 008 could not appear beside Xie Sui as the third young master of the Song family, and he planned to make up the identity of "the poor relatives of the Meng family in the distance" in the future.
Song Yu has very few people who have added to his QQ account. He was lying on the bed and playing with his mobile phone. Looking at the dark profile picture of Jun Qu, he felt a little itchy and wanted to post something.
But today I was racking my brains trying to give bad reviews again, and I ran down the street in the middle of the night again. Exhausted and exhausted.
I don't know when I fell asleep.
It was nine o'clock in the morning when I woke up the next day.
Going downstairs for breakfast, Song Yu was bombarded by Ma Xiaoding.
[Sadako did not forget the well digger: pffhahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahah
[Sadako did not forget the well digger: Brother Yu, is it you who gave the crazy bad review? I deliberately went to eat at his place today, and when I saw Zhu Zhixing's mother's face ashen, she was probably going to die of anger.]
[Sadako did not forget the well digger: Pffhahahaha so talented, I also asked my little brothers to follow in your footsteps, and went to brush a few. Piss off this vicious woman!]
Song Yu was too lazy to care about Zhu Zhixing. Thinking of Grandma Meng's expectant eyes and the stack of papers on the table, he suddenly had a headache.
He drank the milk one by one and sent a message to Ma Xiaoding.
[Your husband, Brother Yu: How are your grades?]
[Sadako did not forget the well digger:? ? ?]
[Sadako did not forget the well digger: Why did you ask this, it's alright...]
If you can get into Jingcheng No. 1 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, but not necessarily good grades in high school. Don't think that you can relax this summer after the high school entrance examination. Others are crazy to apply for cram schools now. There is a lot of competition pressure in No. 1 middle school. Every year, there are jumps from the building. It is lucky not to be seized by the government. High school can not lose at the starting line ah.]
Ma Xiaoding was stunned by his speech like his father.
[Sadako did not forget the well digger: ... Brother Yu, what are you trying to say?]
Song Yu had already returned to the room, pulled out the chair, sat down at the table, and looked at the pile of papers.
[Your husband, Brother Yu: Come to me, I will give you some knowledge. Brothers, let's make the paper together.]
[Sadako did not forget the well digger:…]
This good brother, let's not do it right.
After giving half of the papers to Ma Xiaoding, Song Yu felt a lot more comfortable.
Grandma Meng gave him a lot of materials. During the transition period of junior high school, many of them were to consolidate and review junior high school, and then penetrated high school knowledge point bit by bit. There are even the original college entrance examination questions, just to give him a rough idea of the difficulty.
Except for the first paper, Song Yu was completely unprepared to write it in the first place, and gradually found a little feeling later.
It is very difficult to pull through a paper at the bottom of a book, and 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 power of x and e multiplied by x.
He hadn't planned to try the final question yet, but he vaguely felt familiar, and even a very vague concept appeared in his head. After biting my pen and thinking for a long time, I finally remembered it.
Isn't this a typical example of Lagrange's mean value theorem!
He would still remember this question freshly, probably because the name of the theorem mentioned by the high school teacher was too strange when he expanded his problem-solving ideas.
The theorem given on Baidu, without specific examples, is very confusing. Song Yu just wanted to finish the first conversation with Xie Sui.
So I took a picture of this question and sent him a message.
For the shame of the original A66, he bit his pen and thought about it.
Pretend to be profound.
[Do you know what is Lagrange's mean value theorem?]
Xie Sui was leaning on the bed, tapping his fingers on the computer, invading the Linshui intranet and calling up the surveillance records.
After everything was done, I grabbed the water glass next to me and caught a glimpse of the message on my phone.
[Song Yu: Do you know, what is Lagrange's mean value theorem?]
Xie Sui: "..."
He should be glad he didn't drink water.
Xie Sui's grades have always been outstanding in his student days, and his character is withdrawn and cold, and he has never met any normal classmates.
Therefore, it is impossible to understand the brain circuit of Song Yu, who relies on perseverance to solve problems.
—You have to count even 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 attack him.
Xie Sui took out a pen and a piece of paper, took care of Song Yu's knowledge reserve, wrote down the standard solution of the problem in a well-mannered and detailed manner, and then took a photo and sent it.
[Xie Sui: [Picture]]
[Xie Sui: You don't need that.]
Song Yu waited for a long time before he said these words, accompanied by a picture with clear thinking and beautiful handwriting.
Even simpler and easier to understand than the answer.
Niubi, worthy of being the protagonist, the proud son of heaven.
But when Song Yu got to the point of a horn in his question, he would persevere and continue to ask.
[Song Yu: Then how to solve it with that?]
By the way, I sent a few emojis.
[[scratching head question mark]]
[[ball ball you]]
Xie Sui's finger rested on the little soybean scratching his head, as if seeing the troubled appearance of Song Yu's mobile phone, his expression was a little dazed, and then his thin lips twitched.
[Xie Sui: So want to know?]
[Song Yu: Yes.]
[Xie Sui: Cross out the large section from the third row to the fifth row and change it to "It can be known from Lagrange's mean value theorem".]
"???"
After Song Yu did what he said, he sent out the final grade emotion of being a scumbag.
[Song Yu: There is a number within the interval that makes them equal.]
Xie Sui didn't even want to tell him that it was a theorem. After thinking about it, her eyelashes drooped, and her dark pupils smiled a little bit of wickedness.
[Xie Sui: Didn't I give you a range? You can replace them one by one, and you can always find that number]
Song Yu: "..."
Song Yu: "..."
Your mother's range is infinite!
Why did he always feel that Xie Sui was laughing at him.
