Walking out of the principal's office, Wu Bin picked up his mobile phone and called Gu Fan.

"What for?" After the phone was connected, Gu Fan's voice came from the other end.

"Really going back?"

"yes."

"Don't look at the teacher?"

"What do you think I'm doing when you're interviewing?"

"Why don't you wait for me to come along?"

"I don't want to make you a green leaf for a day, thank you."

"I was convinced by you."

"Heheda, when are you going back to HKUST?"

"Tomorrow."

"I'm in such a hurry, I still want you to come out for a barbecue before you go back."

"Then it's better to hit the day, just tonight."

"Okay, see you at the 6 o'clock bald skewers?"

“OK”

Hanging up the phone, Wu Bin looked at the time and found that it was still early before the lunch break, so he decided to go to Mr. Bi's office first.

Because it was class time, it was quiet in the hallway. As I walked, a nostalgic emotion suddenly came to my heart, and there was an indescribable sense of comfort in my heart.

Slowly pacing to the door of Mr. Bi's office, Wu Bin knocked lightly on the door.

"The door is unlocked."

This voice Wu Bin is also very familiar with, it is Deng Xiuqin, a teacher who teaches mathematics.

So Wu Bin pushed open the door and walked in.

"Hey, isn't this Wu Bin." Deng Xiuqin said with a little surprise when she saw Wu Bin.

"Hello Mr. Deng." Wu Bin waved his hand at Deng Xiuqin.

"Hello, hello, come to Mr. Bi?"

"Yes, is the teacher here today?" Wu Bin asked.

"Here, here, the school is now restarting the competition class, he is full of energy, he guessed that you will come to him today, so ask me to pretend to give you a message, let you go to your previous classroom to find him."

"Oh, thank you, Mr. Deng."

"Let's go." Deng Xiuqin said with a smile.

Finding the door of the classroom with ease, Wu Bin looked in through the small window at the door and found that not only Teacher Bi was inside, but there were also many students sitting below.

'Oh? These students didn't stay in their respective classes on the first day of school, but they came straight here? It seems that the school has really pushed it vigorously this time. ’

"So what do we do here? That is to find the relationship between resistance and speed, so it is a question of functional transformation. ”

Listening to Teacher Bi's angry voice in the classroom, Wu Bin thought about it and decided to wait at the door for a while, anyway, he was not in a hurry.

Standing quietly at the door and listening to Mr. Bi's lecture, the feeling of nostalgia filled Wu Bin's heart again.

It's kind of warm. ’

Within a few minutes, Wu Bin, who was looking at his mobile phone, heard the classroom door suddenly opened, and just when he was surprised, he heard Teacher Bi's voice.

"I knew you were out there."

"Teacher, your ears are so sharp?" Wu Bin turned around and asked.

Bi Wanqing shook his head: "It's not that I heard you, but I know that you will definitely come to me, and then you will definitely not knock on the door when you see me in class." ”

"Haha, the teacher still understands me." Wu Bin said with a smile.

"Come on, come on, come on in, and say hello to your juniors." Bi Wanqing pulled Wu Bin and walked into the classroom.

"Wu Shen!"

"Wu Shen is good!"

"Wu Shen is awesome!"

……

As soon as the students inside saw Wu Bin who was pulled in by Bi Wanqing, they immediately blew up, if only a small part of the freshmen in Xiazhong in the past two years were coming for Wu Bin, then a large part of the physics competition class was coming for Wu Bin.

After all, many people who are inspirational to participate in the competition have been concerned about the event since junior high school, how can they not know a double champion like Wu Bin.

"What does it look like, sit down and sit well." Seeing that the scene was about to be time-sensitive, Bi Wanqing shouted in a low voice.

In an instant, the classroom was quiet again, and the students were sitting quietly.

It can be seen that Teacher Bi is still quite able to control these students.

Nodding with satisfaction, Bi Wanqing pulled Wu Bin onto the podium and said, "Don't be excited, I'll leave time for you to ask questions later." ”

The students below immediately nodded vigorously.

"I'm sure you've all seen your senior in the morning, and you know what honors he has won." After speaking, Wan Qing looked at Wu Bin, "How about you say a few words to your juniors?" ”

"Ah...... I want to say it again. Wu Bin was a little embarrassed, it was really difficult to hold two lectures a day, after all, he had basically finished expressing everything he wanted to say in the morning.

"Just say a few words." Bi Wanqing said with a smile.

"Okay." Wu Bin nodded, supported the podium with both hands, and said after seriously scanning the students below, "Teacher Bi is a good teacher. ”

“……”

"Nothing?" Bi Wanqing looked at Wu Bin and asked.

"You have taught me all these learning experiences, how dare I make an axe in front of your door?"

Bi Wanqing was stunned for a moment after hearing this, and then laughed and said, "You little slippery head, you are really getting better and better at talking." ”

After laughing, Bi Wanqing picked up a piece of chalk and stuffed it into Wu Bin's hand and said, "Then I'll go out for a while, and you can communicate with them." After speaking, he looked at the students below and shouted, "Don't make too much trouble, do you?" ”

"Know~Dao~" the students replied in unison.

"Then tell them." After Bi Wanqing finished speaking, he walked out of the classroom.

"Wu Shen, do you have any cheats left in the school for us to read?"

"Wu Shen, did you also take classes in this classroom before? Where do you sit? ”

"Wu Shen, why do you still have so much hair?"

"Wu Shen, Wu Shen, can you sign my Cheng book?"

……

"Okay, okay, don't worry, come one by one, I'll answer you, can you raise your hand?"

"Good~"

After saying that, all the students raised their hands almost at the same time.

When looking around at all the students in the classroom, Wu Bin suddenly saw a familiar face.

But after thinking about it for a long time, I still didn't remember her name......

"Senior, do you remember me?" Jiang Qingyu saw that Wu Bin looked at him and didn't speak for a long time, so he simply took the initiative to stand up and say.

"Of course, we've been in the preliminaries together." Wu Bin nodded.

"You've taught me a lot of questions." Jiang Qingyu said with a smile.

"Did it help you later?"

"Of course there is, I almost entered the national competition in my sophomore year of high school."

"Awesome, awesome, then we have to make persistent efforts this year."

"I will." Jiang Qingyu smiled and said, "By the way, can I ask a question now?" ”

"Well, you ask."

"Senior, are you free at night?"

"Oh~"

There was an instant commotion below.

"I'm sorry, I've made an appointment with a friend to go to a barbecue."

"Okay~ What about tomorrow?" Jiang Qingyu still didn't give up.

"I'll go back to HKUST tomorrow."

"That ......"

"Ahem!"

At this time, Bi Wanqing's heavy coughing suddenly came from outside the door.
