"Students, the sports day has passed, and now everyone is about to face the first major exam for entering high school, the midterm exam! The significance of this midterm exam is also crucial, it is related to how well you study during this time, and it is also related to the second year of high school liberal arts and sciences. The head teacher Jiang Aiyuan said solemnly.

"Ah......" the people in the class complained bitterly.

"Ahh If you don't work hard now, you will regret it in the future! The head teacher said angrily.

“yes madam！” The class immediately spoke in unison.

Class----

"Ahh Yes! Yes! What kind of test to test, it's not good to waste your time" simply wanted to cry without tears.

"Alas, in this short period of time, the devil knows what I learned," Shen Yu said helplessly.

"I don't know what I've learned," Lin Xuan leaned over and said.

"Why don't you help us cheat and copy it for us?" Gu Xing said with a smug expression.

"No, review it yourself." Yi Chen said coldly.

"Cut, if you don't give it, you won't give it, daughter-in-law, I'll copy it for you, hehe" Su Shuo said with a smile.

"Forget it, you probably did less than me, haha" Gu Xing said solemnly.

"We are all fallen people at the end of the world, why do we have to know each other when we meet, why bother with each other," Mu Yiran sighed.

"Okay, okay, let's hurry up and review, temporarily cramming, can hold a little is a little" said simply.

"Why don't you come to my house after school, and I'll help you tutor together." Yi Chen said lightly.

"Okay," Shen Yu replied.

After School ----

“emm…… I feel like I'm really not learning material, and I can't even understand a single question," he simply shook his head.

"Each other, I'm playing chess with Zhou Gong in class," Shen Yu said helplessly.

"Okay, let's start with this question, the third question on page 26 of the math paper...... If you define operations a⊙b=b, a≥b, or a⊙b=a, what is the value range? Yi Chen asked.

Everyone was silent......

"Forget it, just talk about it." Yi Chen looked at it and asked simply.

"Uh...... This one...... I don't know......" said simply.

"Well, forget it, because f(x)=x⊙(2-x)(1)x≥2-x, i.e., x≥1, f(x)=2-x≤1; (2) When x<2-x is x<1, f(x)=x<1, so the value range is f(x)≤1," Yi Chen said seriously.

"Do you understand?" Yi Chen looked at everyone and asked.

“emm…… I don't understand ......," he shook his head helplessly.

"I don't understand either." Shen Yu looked at Yi Chen with a confused expression.

"Whew...... Call...... ...... "A snoring sound hits......

"Oh, Su Shuo, wake up, Professor Yi will give us another lecture" Gu Xing pushed Su Shuo, who was snoring.

"Huh? What's wrong, what's going on? Su Shuomeng said.

"It's over, the exam is going to be smashed," Lin Xuan said.

"Hmm......" Mu Yiran pandered.

On the day of the test----

"Heavenly Spirit, Heavenly Spirit, Heavenly Spirit, Taishang Laojun will appear soon! Bless me for not failing the exam......" Shen Yu held the pen and muttered.

"Alas, I choose to resign myself to fate, ah~ah~ah~" simply shook his head and said to himself.

"Students, the first Chinese test is the subject of the class teacher, and it is also invigilated by me personally, don't be delusional about cheating, other subjects are the same!" After the class leader Jiang Aiyuan finished speaking, he sent the roll down and passed it from the first group to the last group......

"Students, write your name in the class, I'll check them one by one, but don't end up getting zero points because you didn't write your name," said the head teacher.

"Alas, this is the first question, I won't write it, it's too bad......" Shen Yu looked at the volume and said helplessly.

"I'll ...... I'll copy it for you later," he said in a simple whisper.

After some time......

"Easy, how do you do the second sub-question of the third big question?" Shen Yu whispered.

"The third sentence in the second paragraph of the article ......" said simply and cautiously.

"Quiet!" The head teacher slapped the table.

"You people cheating, don't think I didn't hear it, forget it the first time, don't let me hear it the second time! Write your own papers! The head teacher said majestically.

There was no sound below......

"Jingle bell...... Jingle bell ......"

"Okay, the Chinese exam is over, take a break, and then the math exam will be personally invigilated by your math teacher." The head teacher sorted out the papers and walked out of the class door and said.

"Little Dandan, let's go to the toilet together," Shen Yu said simply.

"Okay," replied simply.

"Next, what about the math exam? I don't know anything," Shen Yu said bitterly.

"Me too, it depends on the situation, can you glance at a little bit" said simply helplessly.

Mathematics Exam ----

emm…… How to do this question? Simply bit the tip of the pen and thought.

A glance to the east and a little to the west......

"Ahem......" Yi Chen coughed lightly twice, and moved the test paper a little to the simple side......

It turned out to be minus one...... Simply snickered.

"Teacher, take a quick look at Yichen's test paper!" Guan Xiaoxiao raised his hand and said loudly.

"Huh? Don't look at other people's test papers! If you find it again, it's considered cheating, and you can retake it! Math teacher Mediterranean stood up and said loudly. He walked over to Yi Chen again and looked at his test papers, and then at the simple test papers......

Midway----

"Teacher! Off Little Cheat Tips! Shen Yu stood up and pointed to the paper ball next to Guan Xiaoxiao and said loudly.

"What?!" Mediterranean said angrily.

Walked up to Guan Xiaoxiao, picked up the paper ball, and said loudly: "Classmate, you just reported others for cheating, and now you are cheating yourself, this speed is too fast, right?" The math teacher asked solemnly.

"Teacher, it's not me, this is Shen Yu who threw it over!" Guan Xiaoxiao denied.

"Don't spew blood! I saw it rolling from the front! Shen Yu said angrily.

"That's it! Guan Xiaoxiao, cheating is your fault, re-examining papers! After speaking, the math teacher took away Guan Xiaoxiao's soon-to-finish test paper and handed her a brand new test paper......

"Teacher...... I ......" Guan Xiaoxiao was interrupted before she could finish speaking......

"A retake is a retake! Let's make rolls! The math teacher exclaimed.

After the exam----

"Yuyu...... You ...... "simply want to talk and stop......

"What's wrong?" Shen Yu asked.

"Did you deliberately make it small?" Asked simply.

"Ouch, my little Dandan, how can you think that, I'm that kind of person? I saw it thrown by the person in front of me! Shen Yu said a little unhappily.

"Okay, okay, I'm just a little skeptical," he said simply, scratching his head.

"You suspect that no one can doubt me, if Guan Xiaoxiao hadn't deliberately reported you before, I wouldn't have thought of reporting her for the math test, I was all for your good, and you doubted me? Woo woo woo ......" Shen Yu said aggrievedly.

"I'm sorry...... I was wrong...... No one should doubt you, even if I doubt you, you are so good to me. I was wrong......" said briefly and hugged Shen Yu.

"Okay, okay, I'm not angry with you, that's Guan Xiaoxiao's deserved," Shen Yu said.

"Hmmm! Thank you, Yuyu, it must be the greatest happiness in my life to meet you! Simply hugged Shen Yu and said movingly.

"Me too, we must all be well, may our friendship last forever! Banzai! Shen Yu shouted.

Best friends, who usually tease each other, are the ones with the most ruthless mouths, but the ones with the softest hearts when you need them......
