"Classmate, which department are you from?" The boy couldn't help but ask.

"I ......"

"Qingyun, if you don't want to come up, give everyone a good talk." Before Su Qingyun could answer, Zhang Huaizhi spoke again.

Hearing him call out Su Qingyun's name, everyone suddenly realized that Mr. Zhang knew this student from a foreign department, so it was estimated that he was a cow in which department.

"Okay." Su Qingyun happily agreed.

She stepped onto the podium step by step, and Zhang Huaizhi stepped aside and gave her the place.

After Su Qingyun cleared her throat, she began to carefully explain what she had just said, which was different from Zhang Huaizhi's interesting explanation, her narration went from shallow to deep, and it was easy for people to follow her train of thought, and slowly, they were immersed in it.

The students were shocked to find that they understood!

"I understand, is this still me?"

"Is it my delusion? Suddenly it felt like my brain had suddenly evolved. ”

"It turns out that this is what it feels like to be empowered."

"It's really new that this can be seen from this perspective."

The boy sitting next to Su Qingyun just now also looked at the book in disbelief, he could actually understand what the book was talking about, it was terrifying!

In fact, it is not that Su Qingyun's lecture method is better than Zhang Huaizhi's, but that she uses the teaching methods summarized by many expert teachers in later generations to explain, which is naturally easier for students to understand.

Zhang Huaizhi on the side also looked appreciative, and sighed with a full face, I didn't see it, this kid is still so good.

Su Qingyun spoke for more than ten minutes before he stopped, looked at Zhang Huaizhi, and said with a smile: "Sir, I'm just here to skip class, so it's almost the same here, but you can't be too noisy." ”

She deliberately said it playfully, and the students in the audience laughed.

"Alright, let's stop here." Zhang Huaizhi nodded and smiled, but did not let her go down, but introduced to everyone, "This classmate, no, can't be called a classmate." ”

Zhang Huaizhi smiled and said: "This is a student often mentioned by many teachers in the school, she should have graduated this year, but she graduated early for some reasons, and she is also your senior sister, a 77-level materials student, Su Qingyun." ”

"Hello everyone, I'm Su Qingyun." Su Qingyun took over the conversation and introduced himself.

Who? Su Qingyun.

The classroom was silent for a second, and then quickly exploded.

", it's her, I said why I was a little familiar when I heard Mr. Zhang's name just now."

"Has it been almost three years since she graduated? How did you get back? I don't know where I am now? ”

"This is the legendary god who crushed all of our science and engineering majors in Huaqing, Su Qingyun? It's a sight to be alive. ”

"Professor Li took her as an example two days ago, but today I met a real person, and it was really amazing."

……

The boy sitting next to Su Qingyun just now was already confused, what? This is the legendary god man, and he even thought that others were bragging?

The boy covered his face, and he didn't want to think about his stupidity just now.

"Jingle Bell ......"

Just as the bell rang for the end of class, Zhang Huaizhi announced the end of class, and Su Qingyun followed him out of the classroom, and the students behind him were still discussing fiercely.

"Qingyun, aren't you at the launch center? How can I still have time to go back to school? In the principal's office, Zhang Huaizhi asked with a smile.

His identity and authority are very high, so he naturally knows Su Qingyun's work address, and there is also a Zhang Sida who left Huaqing.

"I've been on vacation recently and I'm back."

"Then it's impossible to come to Huaqing today just to come and see everyone and listen to the class, right?"

Su Qingyun pursed his lips and smiled, "This is the first, and the second." ”

She took out the big red invitation again, put it on the table, and said respectfully: "Sir, I'm getting married." ”

Zhang Huai was stunned.

"This time, I want to invite you to my wedding banquet with Ji Yue."

"You're getting married?" Zhang Huaizhi reacted with a look of surprise, "This is really a happy event, you and Ji Yue's child have finally become a family member after so many years." ”

He still remembers the first time he saw Qingyun and Ji Yue, a teenager, tall and generous, holding his own painstaking works, talking to everyone, it was really high-spirited.

Zhang Huaizhi put away the invitation properly and said, "Don't worry, I will definitely go to your wedding banquet." ”

He is naturally happy to see these two excellent children get married and reap their happiness.

Su Qingyun smiled slightly.

After coming out of Huaqing, Su Qingyun found his teacher again, Chu Xianming.

Chu Xianming had just finished a class in the afternoon and returned to the office, when he saw Su Qingyun waiting for him, he was surprised and delighted, "You kid, when did you come back?" Why don't you say a word? ”

"Isn't this coming?" Su Qingyun said with a smile,

In the face of Zhang Huaizhi, Su Qingyun was more respectful, and in the face of Chu Xianming, Su Qingyun was a little closer.

"Nothing to do but go to the Three Treasures Palace, tell me, why are you here?"

Su Qingyun was a little helpless, why did everyone think that she was not just here to see them? Although it is true.

She took out the last invitation she had brought with her today, smiled brightly, and spoke in a cheerful tone.

"Teacher, your student is getting married!"

Chu Xianming's eyes widened and he was startled, "You girl is really good, if you don't appear, it's just that, as soon as you appear, you'll be scared." ”

However, the smile on his face could not be hidden, and he read the invitation several times.

"Yes, yes, I still rest assured that Ah Yue's child, you two will definitely be happy."

Su Qingyun looked at him and spoke, "Teacher, there is one more thing. ”

"Huh? What? Chu Xianming raised his head and wondered.

"Ah Yue and I would like to ask you to be the witnesses of our wedding banquet." Su Qingyun said seriously, this is something they had discussed before.

"Witnesses?" Chu Xianming was stunned.

"Yes." Su Qingyun said slowly, "You are my teacher, teach me knowledge, teach me the principles of life, now that I am getting married, I still hope that you can witness the new stage of life." ”

"I ......" Chu Xianming wanted to refuse, but looked at Su Qingyun's envious eyes and stopped talking.

He thought about it, and finally nodded: "Okay, I will be the witness of this marriage." ”

"Great, thank you!" Su Qingyun was overjoyed.

Chu Xianming also laughed.

After sending all the invitations, Su Qingyun returned home.

"Dad, have you sent out all the other invitations?" She didn't see any of the other invitations she had handed out.

"It's almost, I'll send what I need to send." Su Aimin replied.

Su Qingyun nodded, but in a blink of an eye, he saw that there was still an invitation card on the corner of the table, "No, isn't there a ...... this?"

The window was open, the wind blew in, and the red invitation card was opened, and the name on it made Su Qingyun stop his voice.

Su Congwen.

This is the last one, and there is no invitation to send out.
