"Dongdong."

Yi Feng was about to answer when he heard a sound coming from the foot of the table. Gu Muxi kicked it twice.

"Look here." Gu Muxi said in a low voice.

She is writing the problem-solving process in her notebook.

Yi Feng could see that she wanted to help him.

This little girl cares a lot about me.

But such a small problem cannot defeat myself.

Yi Feng was indeed poor in mathematics before the college entrance examination, but in order to get into Guangzhou University of Science and Technology, he sprinted for one month before the exam and successfully got 503 points, exceeding the first-class admission line. However, when he was filling in the volunteer, he was in Gu Muxi.

Under the "coercion", it was changed to Guangshi University.

Later, I studied computer majors that are highly related to mathematics in college, such as advanced mathematics, CNY, and CET-6. I am very proficient in CET-6.

Yi Feng does not think he is a top student, but he can also be regarded as an outstanding graduate of a prestigious university.

How could this pediatrics stump me?

"Why don't you stop talking? You're mute? Didn't you speak happily just now?" Zhao Xue scolded.

Yi Feng smiled slightly, strode towards the podium, picked up a piece of chalk and started writing on the blackboard.

Solution: ∵Complex number z=(x??2x-3)(x3)i is a pure imaginary number.

∴x??2x-3=0,x3≠0, the solution is x=1.

"Teacher, the answer is 1." Yi Feng smiled.

The classroom was quiet and all the students looked at him in surprise.

Even Gu Muxi was almost surprised.

How did Yi Feng improve his math level?

Zhao Xue was also a little confused. Unexpectedly, Yi Feng could answer it. Could it be that he had previewed in advance?

"Ahem, yes, you've got the right answer. You, go back and sit down. You have to listen carefully in class!" Zhao Xue shook his hand and asked him to return to his seat.

Yi Feng smiled, "Yes, teacher."

He returned to his seat and muttered in his heart that what he learned in his previous life was still very useful!

With my current knowledge reserves, it is no problem to crush a college student.

If you take the college entrance examination again, you might be able to win the title of top scorer in the college entrance examination. If you are not the top scorer, you will be in the top scorer.

Thinking of the college entrance examination in 2 months, Yi Feng couldn't help but look forward to it.

"Brother Feng, Niu Pi, I thought you were going to make a fool of yourself!" Wang Tie gave a thumbs up and said to himself.

"Hehe, I mean, I mean." Yi Feng tidied up his clothes.

At this time, a small note was thrown over from the front.

It was a note thrown by Gu Muxi.

He picked it up and took a look.

"You remember owing me a favor!(`へ??*)ノ"

There was also a proud expression on the back of the note.

Xiaopin, she thought it was her credit? That was my own ability?

Yi Feng's eyes rolled, he tore off a piece of paper in his homework book and threw a note for her.

After seeing the note, Gu Muxi showed a look of confusion on his face. When he opened it, his face turned red and he immediately turned back and glared at him in shame.

Seeing this, Wang Tie asked curiously: "Brother Feng, what did you write to School Beauty Gu? Why did she blush?"

"Hehe, nothing." Yi Feng leaned on the chair and said leisurely.

On the other side, Gu Muxi's deskmate, Chen Jiajia, also saw Gu Muxi's cheeks flushed and looked ashamed and angry, and asked curiously: "Muxi, what did Yi Feng tell you just now?"

"What, I didn't say anything. He's just a bastard. When school comes out, I'll deal with him sooner or later!" Gu Muxi said with a concealed look on his face.

She secretly opened the note under the table.

"In addition to owing you a favor, I also owe you a kiss. You can come and pick it up at any time. I'll wait for you~d(^^*)"

"Bastard, if you dare to take advantage of me, I will deal with you when I turn back!" Gu Muxi tore the note to pieces and gritted his teeth.

If I don’t give you some color look, I’m not Gu Muxi!

But she always felt a little awkward, and she felt that Yi Feng was weird today.

Time passes, and it is time to finish school in a flash.

Gu Muxi packed his schoolbag early and left the classroom first.

Yi Feng thought she was a little shy and dared not see her.

Could it be that flirting with her by herself is counterproductive?

It seems that you have to pay attention to it in the future and restrain yourself a little.

As the saying goes, if you are anxious, you can't eat hot tofu. If you are too anxious, it may cause trouble to her.

"Tiezi, let's go home." Yi Feng greeted.

"Okay, Brother Feng!" Wang Tie quickly packed up his books.

Both of them and Gu Muxi live in the same employee community, Guangshi Third Rolling Factory employee community.

Yi Feng's father was a welder in a steel rolling mill, and his mother set up a street stall to sell vegetables outside.

Gu Muxi's father is the deputy director of Zhagang Factory, and his mother is the clerk in the factory.

Wang Tie's family only has one mother who works as a logistics company in the factory. His father is an alcoholic and he stays out all day long.

His parents had already divorced, but every time his father drank too much or had no money in his pocket, he would ask his mother for money.

Yi Feng still remembered that his parents had a few times in the community for this matter.

Later, after the college entrance examination, Wang Tie's mother moved out of the staff community in order to avoid his father.

Because of this, Yi Feng gradually broke off contact with Wang Tie after going to college.

What a great guy, he really regrets that he has separated because of his family.

Since you have lived for a lifetime, you can’t let such regret happen again!

The two left the classroom and came to the parking shed next to the school playground.

There are old-fashioned bicycles parked in the parking shed, Phoenix, and Permanent.

Yi Feng's bicycle is an old-fashioned Phoenix bicycle. It used to be old-fashioned, but it is also a very popular means of transportation for the public now.

He still remembers that it was his 16th birthday, and his father spent 180 yuan to buy it for his birthday gift.

Yi Feng was about to unlock the lock and get the car, but suddenly he found that the tires were flat.

"Damn it! Who tickled my tires!" Yi Feng cursed.

Could it be that a rival of love came to the door so soon?

"Oh, Yi Feng, are your car exhausted? What a pity, it seems you can only walk home!" Gu Muxi riding a bicycle pretended to pass by and smiled.

When Yi Feng heard her tone, he was probably the one who had tied the tires.

"Uh, Brother Feng, why don't you sit behind me and I'll take you back?" Wang Tie patted the back seat of the car.

"Hehe, no need." Yi Feng laughed softly, ran to the back of the bicycle, and jumped into the back seat.

"Okay, Mu Xi will leave."

Gu Muxi glared at him, "Why are you taking my car? Go down!"

"I won't be able to bite me, do you bite me?" Yi Feng said with a thick face.

Gu Muxi grinned, revealing two tiger teeth, "This is what you said!"

After saying that, he grabbed Yi Feng's arm and bit it.

Yi Feng quickly pressed her chin with one hand and held her waist firmly with the other hand.

No matter how hard Gu Muxi bit him, he couldn't bite him.

"You are really a dog? Do you really want to bite me? Fortunately, I was prepared for it! Hehe!" Yi Feng smiled proudly.

"Let me go, I'm going to bite you to death!" Gu Muxi said with his teeth and claws.

The two started to fight by the garage, which attracted the attention of the students around them.

"Hey, isn't this School Beauty Gu?"

"My God, why did she touch a boy?"

"Damn it, it's really school beauty Gu!"
