Zhengyang No. 13 Middle School, the third class of high school classroom.

"Bang!"

The test paper was smashed on the podium table.

A middle-aged female teacher wearing glasses, her round eyes seemed to bulge out of her glasses, and her brows were twisted to form a Sichuan character, and she shouted to everyone in the class, "In the final exam of last semester, your class had the worst average score in mathematics!"

"There are only 16 people in the class who passed, and some of them have less than half of the scores, I don't know what's going on, some of the questions are more difficult, but most of the questions are very simple, and the points you should get must be obtained!"

"The new semester is about to start, and you will soon enter the third year of high school, facing the college entrance examination, what to do and have some points in your heart!"

"In this class, we still do questions and lectures to consolidate the knowledge points of the first and second years of high school. ”

"In the previous time, I will make choices and fill in the blanks, and then we will explain the difficult problems——"

The female teacher stared in one direction as she spoke, her tone became louder and louder, and finally burst out, "Zhao Yi! Zhao Yi! Still lying on his stomach? Still sleeping? I said so loudly, I can't wake you up?"

"Zhao Yi! Zhao Yi ......"

The class burst into laughter.

Zhao Yi slowly raised his head, rubbed his eyes weakly, his eyes were full of confusion, and he seemed to be still reminiscing about the afterglow of the dream, and he was not fully awake.

"Zhao Yi, wake up! The Bull Demon King is angry!" came a funny reminder next to him.

Zhao Yi turned his head.

It was a thin man with glasses, who looked a little obscene, but he felt very familiar, but he couldn't name it.

Instantly, strangeness came to my heart.

Zhao Yi was stunned and looked left and right, his mind was still not clear, and he didn't understand the situation.

He turned his head again to look at the thin man in glasses.

Reach over and put it on your arm!

Pinch hard!

"Oops!" the thin man with glasses bared his teeth in pain, "Zhao Yi, what are you doing!"

"There is a response!"

Zhao Yi was shocked to affirm one thing - not a dream!

He crossed!

Back to the high school days of more than ten years ago!

More than ten years later, Zhao Yi, like most people, is mixed up in school and work.

Academic, mediocre.

Work, mediocrity.

My parents have accumulated a lifetime of wealth, just enough to pay a down payment on a house, and they work overtime every day, and they can barely maintain a relatively frugal life while repaying the loan.

Under the huge pressure of life, the dreams of youth have long been forgotten, and the goals pursued have become vulgar, and occasionally gathering with friends, eating, drinking, and playing cards have become the only way to relax.

Unconsciously, he lived to be the most hated when he was young.

In the dead of night, I occasionally reminisce about life, and the longing in my heart is only regret, "I should study hard in middle school, and if I can be admitted to a top university, the future will be different!"

"You should study hard in college, and then you can change your life by studying in a prestigious school or master's degree!"

"Now, back in time, back in time, can you really go back to high school?"

Zhao Yi finally came back to his senses, and his eyes were about to focus on the podium, when he heard a strange electronic sound--

【Ding Dong!】

【Xueba System Activation......】

He felt something appear in his head, as if it were a legendary system?

The electronic sound continues--

[You have obtained the initial ability "The Law of Cause and Effect"!]

[The Law of Cause and Effect: You can rely on real-world connections to find out the right option among the questions that have the right choice.] 】

When Zhao Yi was immersed in the introduction of electronic music, he sat there motionless, his eyes closed again.

The surrounding classmates looked at it funny, "Zhao Yi fell asleep again?"

"Awesome! Open your eyes, this action ...... I can also fall asleep!"

"Zhao Yi, wake up!"

"Wake up!"

The obscene thin man with glasses next to him pushed hard in retaliation.

Zhao Yi tilted his body and almost fell to the ground, sat up with his hands on the ground, turned his head and glared angrily, "What are you doing——?!"

He got stuck and forgot his name.

"Hahaha......"

The class burst into laughter.

Teacher Niu angrily pinched off the chalk, rushed over in a few steps, his big round eyes were full of anger, and his sonorous words shook his ears, "Zhao ——!

"-Yi!"

She slapped the test paper in her hand in front of Zhao Yi, "Today, you should take it as an exam." If you fail the score, you will be punished for copying the question 10 times and the wrong question 20 times!"

"And!"

"Call your parents!"

Exams, punishment copying, calling parents.

Three in a row!

Zhao Yi looked at Teacher Niu in a daze, not knowing what to react at all.

Teacher Niu went back angrily and distributed the test papers to the first row.

Sun Liang's head leaned over and gloated and teased, "Confess, did you think about Sun Jiali last night, and then, hehehe...... Didn't you sleep well?"

"Sun Jiali is in the second class, and I can't see it, it's too far away, otherwise think about us Xiaoqing? It's right in front of you, and you can see it at any time. ”

Sun Liang's voice was not big or small, just enough for Lin Xiaoqing in front of him to hear.

Lin Xiaoqing is tall, her school uniform covers all the connotations, her long braids are curled at the back of her head, and she is full of youthful heroism.

As a high school girl, her personality can't be said to be bad, and it's far from gentle.

At this time, Lin Xiaoqing's body twisted over, and her tone seemed to be squeezed out of her mouth, "Okay! Monkey! ”

She said that she wanted to be chased, but she raised her fist and waved it, and asked in a threatening tone, "Monkey, do you want to try?"

"Forget it, forget it!"

Sun Liang laughed flatteringly, and waved his finger at Zhao Yi continuously, "Lin Nuxia, this precious opportunity is still left to us Zhao Daxia!"

"Humph!"

Lin Xiaoqing glanced at Zhao Yi, and turned her head absently.

Zhao Yi listened to the conversation between the two and supported his forehead hard, even if he forgot Sun Liang's name, he could directly call Lin Xiaoqing's name, Lin Xiaoqing left him too much impression.

Lin Xiaoqing has always been his front table, the first in the class in academic performance, with strong self-esteem and competitiveness, she seems to be thin and weak, her long braids are full of youth, and she is actually a real female man.

She's really fierce!

When I was in my first year of high school, a senior confessed to Lin Xiaoqing in public, Lin Xiaoqing felt very embarrassed, and beat up the senior in anger, and the poor senior had to transfer to the school because he was too embarrassed.

Since then, no one dares to chase Lin Xiaoqing.

The test papers were passed over.

Zhao Yi already had the test papers, but he just helped pass the test papers to the back row, and he also paid attention to the test papers.

Zhao Yi looked down at the test papers, there was a sense of novelty, he made up his mind to work hard, "I have more than ten years of memory, and I even passed advanced mathematics, can ordinary high school math questions still stump me?"

Look at the question.

...... the first multiple-choice question?

What？

Before I saw the end, I was hit by 999+ in my heart.

It's been more than ten years!

The knowledge of high school has long been forgotten, and the complex mathematics that is basically unused in life is even worse.

π only know that it is pi, do you want to convert it to 3.14?

Also, what is e?

"At this level, it's not as good as before!" Zhao Yi thought that he was already in his third year of high school, and suddenly felt a huge pressure.

He saw the parentheses at the end.

At this time, a strange feeling arose in my mind, as if I could directly know the answer options by using one ability?

Zhao Yi was full of novel feelings, and he was sure that his feelings were right.

Looking at the exam paper is completely different.

Most of the multiple-choice questions on the paper he doesn't know how to do at all, but he knows that he can know the correct answer to the question in a way?

Zhao Yi was a little unaccustomed to it, but he immediately grasped the point--

If you can't understand the question, you can know the answer!

"This is the ability given by the Xueba system?"

【Turn on the system!】

A thought, a set of data comes to mind.

[Name: Zhao Yi.] 】

[Brain domain development: 5.3%]

[Wisdom: 60.] 】

[Energy: 100/102.] 】

[Learning Coins: 0.] 】

[Ability: "The Law of Cause and Effect.] (To activate the next stage of ability, you need to consume 1000 Learning Coins.) ）】

There is not a lot of personal data in the system, and for each piece of data, you can know how useful it is if you pay close attention to it.

Brain domain development is an evaluation of the brain's ability, which directly affects attributes such as wisdom and energy, and can even be related to physical condition.

Wisdom is a very complex evaluation, involving the breadth of knowledge, logical thinking, the ability to observe things, and even the causal thinking related to the system.

Energy is the same as ordinary people's understanding.

Everyone's energy is limited, and long-term use of the brain will feel tired, the ability of "The Law of Cause and Effect" consumes energy, and the ability to use it is much higher than the normal use of the brain to solve problems.

Learning coins are like money, which can improve concentration and replenish the energy consumed, and the way to obtain them is related to daily behavior.

After Zhao Yi understood the general situation, he looked at the questions on the test paper again, and couldn't wait to test his ability.

Question 1.

"Known set A={x||4x-1|>...... Then what is the interval of A+B?"

[The Law of Cause and Effect!]

[Answer: C. 】

"You don't even have to look carefully at the options to know that the answer is C!"

Zhao Yi took a deep breath and filled in the answers in parentheses, he also paid attention to the personal data of the system at the same time, and the energy on the panel was consumed by 1 point.

Next question.

"If the plural number a+2i/1+2i(...... Then the value of the real number a is ?"

[The Law of Cause and Effect!]

[Answer: A. 】

Next question.

“......”

“......”

Zhao Yi read and browsed the options one by one, and quickly completed the ten multiple-choice questions at an average speed of less than ten seconds.

Further down is embarrassing.

At present, in the test papers of the formal college entrance examination, multiple-choice questions account for only one-third of them, that is, the total is 50 points.

Teacher Niu said that only doing 'small questions' also includes choosing to fill in the blanks at the back.

"But ......"

Zhao Yi carefully calculated, ten multiple-choice questions are fifty points, and six fill-in-the-blank questions are twenty-four points.

50/74=？

More than two-thirds?

Passed!

Zhao Yi suddenly exhaled lightly, and when he relaxed, he felt tired, glanced at the energy attribute, and was surprised to find that sixteen points of energy were consumed?

Too fast, right?

Ten multiple-choice questions consume sixteen points of energy, and if you change to so many multiple-choice questions on the English test paper, the negative value of the energy squeezed is not enough!

"While the ability is good, the attrition is also an issue. ”

Zhao Yi pondered carefully, stretched tiredly, suddenly felt the softness on his elbows, and turned his head a little strangely.

A dark shadow.

Strong!

Wide bull's eye!

The Bull Demon King looked at Zhao Yi in a daze, his face turned from white to red, and then from red to black, and his trembling body seemed to be brewing with the power of a volcanic eruption.

[Flirting girl, target: Niu Lotus, learning coin +1.] 】

Zhao Yi's neck twisted back stiffly, looked at the test paper and pretended that nothing had happened.

I heard an angry roar behind me.

"Zhao Yi!"

"Sleep in class, don't take the questions seriously, affect your classmates, and have a bad attitude......"

Teacher Niu yelled a series of times, and finally pointed to the door of the classroom, "Get out!"

"Yes, yes!"

Zhao Yi stood up awkwardly, as if liberated, and rushed out of the classroom.
