After dressing as a vicious male supporting character, I attacked the male protagonist

Tutoring is a must.I haven't finished my high school mathematics, and I can't even memorize the formulas. I only have a shallow impression of the quadrant root. How can I learn this?

Not to mention that next week's midterm exam will take advanced mathematics and calculus...

"Let's put those two aside for now."

At ten o'clock in the evening, Huaijiu lay on the table, yawned sleepily, and discussed with Gu Yinglou, "The high math teacher gave the original question, and it's not too late to review it in the last two days. My knowledge of insurance and freight forwarding is not yet look..."

Gu Yinglou was watching Downton Abbey. He took off one earphone, revealing a series of fast and humorous British pronunciation.

He raised his eyebrows slightly and asked, "What does this have to do with me?"

Huaijiu: "..."

"Since you haven't reviewed well in other subjects, you should get up early, don't play with your mobile phone, and pay close attention to reading two more knowledge points every minute and every second. Instead of delaying time when I tutor you in advanced mathematics."

"But."

Holding the pen holder, Huaijiu poked the draft paper in front of him with the round and small nib, and replied sullenly, "There is no need to be in such a hurry, and every time you assign homework, it takes a lot of time, and I am not the only one who is procrastinating. "

"..."

Gu Yinglou slapped the newspaper beside him, and said in a clear and stern tone, "I'm using my spare time to help you with tutoring, can this be the same? I know what you mean, you want me to tell you about the teacher's drawing directly. Did you come up with a question? Do you think this is saving time? No, I tell you, this is cheating!"

Teacher Gu's eyes were deep, and he clicked until he stopped, "With your learning attitude, do you still want to take the postgraduate entrance examination?"

"..."

Huaijiu opened his mouth slightly, his face flushed as if he had drunk three bottles of white wine.

What Gu Yinglou said was straightforward, but he was right.The learning atmosphere of third-rate universities is already a bit substandard, it all depends on the self-consciousness of the students, not to mention that the postgraduate entrance examination is a single-plank bridge crowded by thousands of troops, and if you don't pay attention, you will already fall off the cliff.

Ashamed of the lazy thoughts that flashed just now, he took out eyedrops and dripped two drops into his eyes, drank two more sips of cold coffee, and continued to do the quiz with the light on.

Gu Yinglou put the earphones back on, and leaned on the ergonomic chair while listening to the drama while flipping through the books.

Under the cold white light, as soon as he raised his eyes, he could see Huaijiu's sleepy eyes.

He yawned heavily, his jaw about to drop to the paper.Moreover, his posture of holding the pen was a bit wrong, the pen holder rested abruptly on the phalanx, pressing out shallow imprints one after another.

Huaijiu bit the penholder, and after all the calculations, the answers were all exaggerated, so he had to start over.He rewrote a line of formula, and before he could calculate it, a large black shadow suddenly appeared in front of his eyes——

Gu Yinglou put down the book and strode towards him.He leaned on the desk with one hand and looked down at the cup of wine. His shirt was rolled up one after another, revealing a strong wrist.

"Just such a question, I did it for 10 minutes."

He clicked his tongue twice, turned the notebook over, looked at the barred part, and quickly shook his head, "The thinking is wrong, no matter how hard you go into a dead end, it will be in vain."

"Pen."

"Ah... oh."

Huaijiu hurriedly handed him his fountain pen, with two clear and small tooth marks on the top.

Gu Yinglou took a look, wiped it with a paper towel, and then quickly calculated it on the draft book of Huaijiu, and gave a few words of verbal guidance, "The numerator and denominator of this question are about zero, and it can be guided in a limited area. Then you can find the derivative and judge whether the limit exists... The result here is uncertain, so we must continue to use L’Hopital.”

His mental arithmetic ability is very fast, and the calculation is not particularly complicated. He can write the answer almost at a glance. It only takes less than 2 minutes from reading the question to writing the answer.

Let a certain child in front of you be dumbfounded.

Gu Yinglou raised his eyebrows, "Do you understand?"

"Um……"

Huaijiu wanted to nod at first, but after hesitating for two seconds, he calculated it according to his memory, and after confirming that there was nothing wrong, he replied, "Understood."

"It is already eleven o'clock."

Gu Yinglou tapped his watch, expressionless, "Come and ask me next time, don't waste time."

"..."

Huaijiu was stunned by his domineering tone, "Okay, I get it."

"Let's be here today."

Gu Yinglou slowed down his tone, "I have another meeting tomorrow, so you should go to bed early."

So fast?

He thought he was going to be kept until twelve o'clock.

Huaijiu was a little surprised, he didn't know why, he always felt that today's Gu Yinglou was a little weird, but he couldn't explain why.

12:30 in the middle of the night.

Gu Yinglou raised his hand slightly to block the moonlight coming through the window.

He sighed, turned on the night light by the bed, walked out of the room wearing the cotton slippers that Aunt Zhang had prepared for him.The villa was silent and dark, and the slippers creaked slightly as they stepped on the wooden boards.

The voice-activated lights in the corridor moved upon hearing the sound, and the small velvet yellow lights gradually lit up, illuminating the way to the kitchen for him.

Gu Yinglou opened the refrigerator door, and it was filled with leftover ingredients such as frozen beef, Australian lobster, and broccoli.

He turned over layer by layer, expressionless.

The cold air from the refrigerator drifted faintly in front of him, Gu Yinglou stood there for more than ten seconds, silently took out his mobile phone, and sent a text message to Ye Xian.

late at night.

Ye Xian turned over and heard Gu Yinglou's exclusive text message reminder, trembling with fright in his sleep, he began to touch his phone vaguely.

On the dark phone screen, two new text messages from Gu Yinglou were displayed.

Gu Papi: I want to eat instant noodles.

Gu Papi: Bring me two packs tomorrow. I want the old altar sauerkraut flavor, and bring me a boiled egg by the way.

Ye Xian: "..."

Ahhh, go to hell, Gu Bapi!

With Gu Yinglou's friendly joining and devil training, the efficiency of Huaijiu's review has been greatly improved, soaked in the library and study every day, and finally made it to the midterm exam.

The exam went smoothly that day, except for some minor disturbances in the subject of high mathematics.

Everyone happily took the miniature cheat sheet to the exam, especially Zhang Peng, who didn't bring the cheat sheet, but brought a mobile phone.When he entered the classroom, he looked up and saw that the customs declaration teacher was wearing a formal suit, and his sharp eyes looked at him coldly through the glass lens.

"..."

Zhang Peng was almost scared to pee.

The customs declaration teacher's surname is Zhang. She is strict in class and even stricter in exams.After one exam, seven or eight students who cheated were caught, even the girls didn't show any affection at all, and did business as usual.

Huaijiu opened the test paper and keenly noticed that the math teacher had changed the last two big questions. The method was the same, but the shell was changed.And when reviewing, aiming at this knowledge point, Mr. Gu also specially changed three forms to test him. The thinking and process of solving the problem can be memorized by heart.

It took him half an hour to complete all the previous single-choice and multiple-choice questions. When he finished the last two big questions, he circled the key words in the question stems, calculated it on the draft paper, and then checked it again. Check whether there is a calculation error, and finally write it neatly on the answer sheet.

Huaijiu wiped off the rubber crumbs on the surface of the roll, checked it roughly, and then packed up and prepared to hand in the roll.

As soon as he stood up, all the students in the classroom immediately raised their heads like sunflowers, and all their eyes were focused on him.

Xu Yaoyao was also surprised, she was already considered a top student in her class, but now she just started to do the last two big questions...

He was the first to hand in the paper, did he give up?

She was a little worried, but thinking about it, classmate Huai's basics were not good, knowledge points such as rote memorization were okay, but it was quite difficult to improve high math in such a short period of time.

I hope the teacher will stop failing his subject because of his hard work.

Xu Yaoyao thought about it, but she still buried her head and continued to write her paper.

Huaijiu didn't notice the brains of these girls, he folded the test papers and sent them to the podium.

Teacher Zhang was turning off the students' mobile phones one by one. When he saw him coming up, he thought something was wrong. Unexpectedly, the boy took out a neat paper, handed it to her, and asked worriedly, "Teacher, you can leave early now." field?"

???

That's it?Isn't it fake?

"……Can."

Teacher Zhang came back to his senses and glanced suspiciously at the scroll. The font was neat and there were no traces of large-scale alterations.

Should have really reviewed it.

No matter how many exams you take, as long as you have the heart to learn, progress will always be foreseen.

Her expression softened instantly, "Okay, you can go."

Huaijiu nodded and walked out of the classroom, not in a hurry.

After about 10 minutes, people began to hand in the papers one after another, and most of the people who came out were the well-known scumbags in the class.A boy who had a good relationship with him even patted him on the shoulder and said jokingly, "I guess we're going to rebuild together again."

Huaijiu chatted politely with him, and Zhang Peng handed in the paper. When he saw him standing outside the door, he was moved to tears, "Brother Huai! I thought you were gone!"

Huaijiu vaguely revealed the past, "Didn't you say you're going to eat sashimi after class?"

In fact, it was because Gu Yinglou got off work on time these days. If he didn't stay with Zhang Peng, he would have to go home early, and then start working on the fourth grade paper that Teacher Gu assigned yesterday...

Desperate just thinking about it.

It's hard to finish the exam today, let him take a breather and rest for a while.

"Huh? Did I say that?"

Zhang Peng remembered two seconds, with a confused face, "Then go eat sashimi. By the way, Brother Huai, why did you write the paper so fast today? I don't think Yaoyao did it as fast as you. You made it up ?"

"If I do it blindly, can I still wait until five or ten minutes into the exam before handing in the paper?"

"What?! Did you do it yourself?"

Zhang Peng was shocked, and at the same time deeply remorseful, "I would have poked you if I knew it earlier, and I would have looked at your answer..."

"Don't think about it, I won't show it to you. Teacher Zhang is so strict in proctoring the exam, do you still want to copy?"

Huaijiu patted him on the shoulder, and said earnestly, "Besides, it's not safe to copy the exam papers. Only what you learn by yourself truly belongs to you."

"..."

What's wrong, the person who hated studying the most in the past not only reviewed before the exam, but also lectured him...

Zhang Peng got goosebumps all over his body, and quickly changed the subject, "By the way, brother Huai, today my brother held a pool party at home and invited many beauties, so you should come and play too!"

"I do not……"

"No no no no!"

Zhang Peng grabbed his arm involuntarily, "If you continue to read like this, you will lose your mind. Let's go, we brothers haven't had a drink in a long time, so we must have a drink to our heart's content today!"

Huaijiu hesitated for a moment, "Then I..."

He glanced down, he forgot to charge his phone before he came out, and it was turned off now.

He couldn't send text messages, and he didn't remember Gu Yinglou's phone number.

... Then go to Zhang Peng's brother's house, find a plug to charge the battery, and then talk about it.

·

Gu Yinglou was sitting on the gaming chair in the study room, with his head slightly propped on his wrist, staring blankly at the two packs of instant noodles on the desk.

Aunt Zhang knocked on the door and asked him through the door, "Master, it's time for dinner."

Gu Yinglou raised his eyelids, and his gaze fell on the screen of the mobile phone, where the two failed call records were particularly conspicuous.

He was silent for a long time, and finally stood up, "Understood."
