After realizing that I had been reborn and time-traveled, I looked at my white and slender hands. I looked in the mirror and saw a pretty face. 

I looked more beautiful than I was before, but there were faint dark circles beneath my eyes. It was obvious that I hadn't slept well for a long time.

I looked down. Gosh, I'm still wearing a cast on my leg.

On the desk, revision books were neatly piled up, as well as the notes and exam papers. 

The marks were low. 

At this moment, everyone was doing homework. I look around and spotted some acquaintances. I wanted to ask my deskmate about the current year, but he interrupted me impatiently, "You're so annoying." 

It seemed that the original owner of this body was not very popular in class. 

So I gave up talking and began reading through the test papers on the table. It was written from the year 2020 to 2021. It had been two years since my college entrance examination, and my first year becoming a corpse.

The owner drafter a whole page of notes but failed to solve the second question. I looked at it and found that her calculations were wrong. 

I sighed, picked up the pen, and began to calculate.

It took me only 15 minutes to finish the question. At this time, several students were already discussing the answer in a low voice.

I also changed the answers to the first few questions as I listened.

I heard someone behind me saying that the answer was negative. I turned my head and chimed in, "Yes, your answer is right. What did you use..."

They looked at me as if I were some kind of fool. They ignored me and carried on with their discussion. 

My head was filled with questions.

At this time, the teacher came in from the door. He was a bald middle-aged man with a pair of glasses on his nose bridge. He asked skilfully, "So, who had finished it? The questions today were quite difficult."

I raised my hands as well, but there was a burst of laughter.

The teacher looked at me in surprise, "Sun Shuyi, did you hear what I asked?"

I nodded. The teacher shook his head and said, "Don't joke with me now. Hurry up and show me the corrections you made yesterday."

I looked through my notes to find the test paper he asked for. When I looked up, the teacher had already begun to discuss the answer with the students who had completed the test paper. 

Meanwhile, there were full of red markings on my paper.
