The world was originally a wilderness, but we stepped out of the way.

I just went to the supermarket to buy the ingredients and prepare to make my own dinner. The phone on the table vibrate. I walked over to the table and picked up my phone and glanced at it casually. It turned out to be an email prompt, and I looked at the headline of the email, and the sudden joy enveloped my whole body, making me indescribable. I saw that it was clearly written:

"Admission Letter from China University of Science and Technology Development."

I quickly opened the email and read it:

"Hello Cheng Yin, you have been officially admitted to China University of Science and Technology Development of our university."

……

I couldn't believe my eyes. I looked at the email again, word by word, for fear of slipping out a single word.

"Hello Cheng Yin, you have been officially admitted to China University of Science and Technology Development of our university."

……

Really, yes, I was admitted!!!!!!!! I was admitted!!!!!!!!!!

That's great. I'm going to tell Arthur, Xiaoyu, the dwarf, and Yan Xiaoxue.

By the way, and Professor Wu!

Oh no, I laughed and patted my head. What a fool, he should have known the news before I did, and I was overjoyed. I laughed at myself and looked out the window at the sky—it was clear and cloudy, and it was a little reddish.

September 1, 2021 at 8:20 a.m.

This morning's weather was exceptionally clear, and the aroma of the grass was rushing towards me, and I rode my bicycle down the campus road. I looked at my watch at 8:20 and there were still 20 minutes left before the 8:40 class. Looks like it's enough for me to go to the school cafeteria and buy a breakfast. Today is my first day as a graduate student at HKUST, so I should be in a good mood no matter what.

Thinking of this, I hummed a little song and walked into the cafeteria.

After buying breakfast, I parked my bicycle in front of the first school building. I walked quickly to the classroom on the second floor. I expected more people to arrive early on the first day of school, but I was wrong.

When I walked into the classroom around 8:30, the whole classroom was empty, except for one student sitting there, looking intently at the textbook on the desk. The classmate, a man in his early 20s wearing a short-sleeved shirt, cropped trousers, and square-rimmed glasses, walked over softly and sat down in the row behind him. But he still seemed to notice me, looked back at me, pushed his glasses, and greeted me shyly.

"Classmate, morning."

"Early."

I greeted him politely, then put my backpack on the seat next to me, and took out my notebook and black pen and placed it on the table. Just as I took out my textbook and was about to look at him, he had already moved to my side, looked me up and down carefully, and then pointed at me excitedly: "You, you, aren't you the classmate who fought gringos at the lecture?" It's a great honor for me to be in the same class as me. ”

"It's not a big deal, I'm just an ordinary student like you." Out of politeness, I took the hand he stretched out to me.

Ay...... Why did I mention the matter of the lecture again, my heart is helpless.

But he didn't seem to pay any attention to what I said, and introduced himself to me seriously, "My name is Cui Li, and my undergraduate is also from the University of Science and Technology, so I am considered a half-guaranteed student." We will be classmates in the future, and I hope you will take care of it. ”

"Hello, my name is Cheng Yin, please take care of me."

I casually dealt with Cui Li, shook his hand again, and then leaned on the table and ate the breakfast I had just bought from the cafeteria.

"You've just come to our school, right? I'm not familiar with this place, but I'll tell you that our school is good, not only the location is good, but the food in the school is also good..."

Cui Li didn't mean that I had automatically ignored what he said, but he continued to talk about the school that he was proud of.

Before you know it, the whole classroom has been filled. The quiet classroom has gradually become noisy. I quickly finished my breakfast and looked left and right, waiting for the first lesson to begin.

As the class bell rang, a hunchbacked old man on crutches in a dark gray suit, holding a few books in his left hand, walked slowly into the classroom, and then stood in front of the podium.

"Ann, Ann, Ann, Ann, Quiet...... Up, up, up, up, class. Students...... Open the book. ”

There was a snickerle of laughter from below, and from time to time a few mischievous students were imitating his way of speaking. I couldn't help but secretly laugh too.

"Laugh, laugh, laugh, laugh what laugh. Give it all to me...... Quiet ...... Listen! ”

I held back my laughter, pushed the arm of Cui Li, who was smirking on the side, with my hand, and whispered to him: "Didn't you say earlier that you are familiar with this place?" This professor, you know? ”

"You say he's not a professor, he's just a lecturer."

"Lecturer?"

"yes." Cui Li glanced at his name written in front of the podium, and then stammered to introduce his lecturer Hu Zaide, and continued, "This Hu Zaide is not fluent enough, but his ability to teach high mathematics is really good, it is said that he has published several papers that shocked the whole country, and has won several national academic research awards, but it is a pity that this oral expression ability is too poor, and people are pedantic and do not know how to be ingenious, so for so many years, they can only be mixed into a lecturer, and they have no chance to be a professor and other titles." ”

"I see."

I held my head with one hand and rubbed the footer of the book with the other, looked at the stuttering Hu Zaide seriously writing the formula on the blackboard, and shook my head helplessly.

"With... Same... Students, we... Today... Speak... Explain... Textbook... First... Chapter. Hu Zaide opened the textbook on the podium.

My gaze deliberately rested on his sleeve-rolled arm, which was rough but unslain. After all, he didn't have a chance to be a professor, and there was no scar on his arm, so that "Z" professor shouldn't be him.

Thinking like this, I lay on the table in a daze, listening to Hu Zaide's stuttering in a daze, which was like a lullaby, turning my books into a double and unconsciously bringing me into a dream.

"Hey, hey, wake up." I opened my eyes and looked at Cui Li in front of me.

"What's wrong?" I looked at him with a confused expression.

"Cheng Yin, the teacher asked a question." Cui Li whispered to me.

I quickly got up from my seat and looked at the blackboard full of mathematical formulas.

"It's... Bit... Same... Same... Learn, please... For everyone... Again... Again... Explain this formula... of... Usage. Hu Zaide watched as my saliva dripped down the corners of my mouth onto the desk.

I looked at Cui Li awkwardly, he wrote all the formulas on a piece of paper, and I read them all along with the above.

"Very... Good... Well, explain... Of the very... Arrive... Arrive... Bit. ”

Hu Zaide's speech was still the same inaudible. I slowly sat down in my seat.

The first class I wanted to take turned out to be like this. I looked out the window at the blue sky and soon fell asleep again...
