Zhengyang No. 13 Middle School, Class 3, Class 3, High School.

"Bang!"

The test paper hit the podium table.

A middle-aged female teacher wearing glasses had her eyes wide open as if she was protruding from her glasses, and her frown brows formed the character Sichuan. She shouted to everyone in the class, "In the final exam last semester, your class has the worst math average score!"

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

"The new semester is about to begin, and you will enter the third year of high school soon. Facing the college entrance examination, I know what to do!"

"In this class, we will do questions and teach questions to consolidate the knowledge points of the first and second grades of high school."

"In the previous time, we will finish the choices and fill in the blanks, and we will explain the difficult questions later."

The female teacher stared at one direction while talking, and the tone became louder and louder, and finally burst out suddenly, "Zhao Yi! Zhao Yi! Still lying down? Still sleeping? I said so loudly, but I still can't wake you up?"

"Zhao Yi! Zhao Yi..."

The whole class burst into laughter.

Zhao Yi slowly raised his head and rubbed his eyes weakly. His eyes were full of confusion, as if he was still savoring the afterglow of the dream, and he did not fully wake up.

"Zhao Yi, wake up! The Bull Demon King is angry!" A funny reminder came from the side.

Zhao Yi turned his head.

He was a thin man with glasses. He looked a little vulgar, but he felt very familiar, but he couldn't name him.

In an instant, strangeness surged into my heart.

Zhao Yi stared at the left and right, still not clear-headed, and he was a little confused.

He turned his head and looked at the thin man in glasses again.

Reach your hand and look at your arm!

Pinch it hard!

"Ouch!" The thin man in glasses grinned in pain, "Zhao Yi, what are you doing!"

“There is a reaction!”

Zhao Yi was shocked and affirmed one thing--not a dream!

He traveled through time!

Back to high school days more than ten years ago!

More than ten years later, Zhao Yi, like most people, hang out in school and work.

Academic, mediocre.

Work, mediocre.

My parents have accumulated wealth for life, and they only have enough to pay the down payment for a house. They work hard every day and work overtime only while repaying the loan, they barely maintain a relatively frugal life.

Under the huge pressure of life, my dreams when I was young have long been forgotten, and my goal has become vulgar. Occasionally, I have gathered with friends, had dinner, drank, and played cards with them, and became the only way to relax.

Before he knew it, he lived the most annoying thing when he was young.

When the night is late, I occasionally recall my life, but only regrets are left in my heart. "You should study hard in middle school. If you can get into a top university, the future will be different!"

"You should study hard in colleges and study in a prestigious university. A master's degree can also change your life!"

"Now, I've traveled through time? I've returned to the past? I can't really go back to high school?"

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

【Dingdong!】

【School-Big System is on...】

He felt something appearing in his mind, as if it was a legendary system?

Electronic sound continues-

[You have obtained the initial ability "The Law of Causality"!]

["Cause and Effect": You can rely on the relationships in the real world to find the correct options in the questions that have the correct options.]

When Zhao Yi was immersed in the introduction of electronic sound, he sat there motionlessly and his eyes closed again.

The classmates around him looked at him with a funny look, "Did Zhao Yi fall asleep again?"

"Awesome! With your eyes open, you can fall asleep even with this action!"

"Zhao Yi, wake up!"

"Wake up!"

The slutty and thin man wearing glasses next to him pushed hard with revenge.

Zhao Yi almost fell to the ground with his body tilted, and sat up with both hands, turned his head and glared at him and said, "What are you doing! Sun?"

He got stuck and forgot his name.

"Hahaha……"

A loud laughter sounded in the class.

Teacher Niu cut off the chalk in anger, and Fengfeng rushed over in a few steps. His big eyes were full of anger, and his sonorous and powerful words made him buzz in his ears, "Zhao!

"Yi!"

She slapped the test paper in front of Zhao Yi, "Today, you just think it's an exam. If you fail the score, you will be punished to copy the questions ten times and copy the wrong questions twenty times!"

"besides!"

"Call your parents!"

For exams, copying is punished and called to parents.

Three consecutive days!

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

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

Sun Liang's head came over and teased gloatingly, "Tell me, did you think of Sun Jiali last night, and then, hehehe... didn't sleep well?"

"Sun Jiali is in Class 2 and can't see her. It's too far away. Otherwise, consider us Xiaoqing? She's right in front of you and can see her at any time."

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

Lin Xiaoqing is tall, her school uniform covers all the connotations, her long braids are on the back of her head, and her whole body is full of youthful heroism.

As a high school girl, her personality cannot be said to be bad, nor can she be said to be gentle.

At this time, Lin Xiaoqing twisted her body, and the tone seemed to squeeze out from her mouth, "Okay! Monkey! Make fun of me? No one is chasing me, so I can also experience the feeling of being chased."

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

"Forget it, forget it!"

Sun Liang laughed in a flattering way and waved his hands to Zhao Yi continuously, "Mr. Lin, let's leave this precious opportunity to us, Daxia Zhao!"

"snort!"

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

Zhao Yi listened to the conversation between the two and held his forehead hard. Even if he forgot Sun Liang's name, he could call out Lin Xiaoqing's name directly. Lin Xiaoqing left a deep impression on him.

Lin Xiaoqing has always been his front desk, the first in the academic class, has a strong self-esteem, and is the top leader in competitive strength. She seems thin and weak, and her long braids are full of youthfulness. She is actually a real tomboy.

She is really fierce!

When he was in the first year of high school, a senior confessed to Lin Xiaoqing in public. Lin Xiaoqing felt very embarrassed and was so angry that she beat the senior up. The poor senior had to transfer to school because she was too embarrassed.

Since then, no one dares to pursue Lin Xiaoqing again.

The test paper was passed.

Zhao Yi already had the test paper, but he just helped to pass the test paper to the back row, and he also focused on the test paper.

Zhao Yi looked down at the test paper and felt a novel feeling. He made up his mind to work hard. "After more than ten years of memory, I even passed the advanced mathematics. Can ordinary high school mathematics problems still stump me?"

Read the question.

The first multiple-choice question...?

What?

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

More than ten years!

I have long forgotten all the knowledge in high school, and the complex mathematics that I can't use in life is even worse.

I only know that π is pi, should I convert it to 3.14?

Also, what is e?

"At this level, it's not as good as before!" Zhao Yi felt extremely stressed when he thought that he had already entered the senior year of high school.
