As soon as the voice fell,

Causes intense discomfort to all PhD students.

“？？？”

“？？？”

“？？？”

Is he confused?

Or are you too confident?

Questioning the professor's lack of streamlining of the problem-solving process?

Every Ph.D. student doesn't believe Xu Mang's words, but they are also looking forward to the content of Xu Mang's words, if he can prove that the professor is wrong, it means that sometimes the professor is not absolutely right.

The professor was stunned for a moment, and looked at Xu Mang carefully, isn't this guy the one who smirked in class?

"Do you have the most streamlined process?" the professor asked.

"Yes!" Xu Mang nodded.

"Okay. The professor said, "Come up and explain." ”

"Oh. ”

After Xu Mang got the answer, he walked all the way to the podium, and on the way he felt the questioning eyes of many people about him, which is also a normal phenomenon, not to mention them, if he encountered this situation, he would have changed his disdainful gaze a long time ago.

The quality of the PhD students is still high... At least a lot taller than myself.

"Professor?"

"Can you help me get a projector?" Xu Mang said embarrassedly, "I wrote it by hand..."

"Good. ”

soon

The professor gets the projector ready.

Xu Mang's handwriting is very clear, and then he began to interpret his content, the previous steps are almost the same, Xu Mang just said a few words, but in the middle part, Xu Mang focused on it.

"The front is almost the same as the professor, but in the middle part I bypassed some questions. Xu Mang said indifferently: "I think the next seven or eight steps are a waste of time." ”

Words fall,

A student in the mathematics department asked, "What evidence do you have to prove that you are more streamlined than the professor? Why do you not make mistakes? Do you think it is reasonable that you are missing seven or eight steps for no reason from logical thinking?"

This is a question that touches the soul!

Xu Mang looked at this student, isn't this the little money classmate just now.

"Professor?"

"Can I respond to this student's question?" Xu asked.

"Yes!"

"I'm curious about it too. The professor nodded.

"Ahem!"

"You're right. Xu Mang said with a smile: "Just now I just talked about the difference between myself and the professor, and this difference is that the seven steps in the middle have been omitted, and now I will analyze why I am omitted and why I am omitted." ”

As soon as the voice fell,

Xu Mang inserted the USB flash drive into the computer.

Then click on a document, and everyone sees a delicate mathematical model.

"This is a mathematical model I made yesterday, and I will use the model data to carefully analyze it for you later, and after removing the seven steps, it is correct or not. Xu Mang said with a smile to the students present.

“...”

“...”

“...”

Boy...

Can this be a mathematical model?

In the time that followed,

Xu Mang carefully explained it from beginning to end, and finally ten minutes later, he drew a perfect end to the question of whether to eliminate the middle seven steps.

Glancing at the expressions of these PhD-students present, Xu Mang showed a relieved smile.

It's supposed to be autistic, right?

"Are you?" the professor stood on the side, looked at Xu Mang, and asked with a puzzled face, "Aren't you studying for a doctorate?" ”

"Huh?"

"Oh..."Xu Mang nodded awkwardly and said, "I'm not studying for a doctorate, and I'm not from this school." ”

“？？？”

“？？？”

“？？？”

He's not a big kid?

How did that end up here?

What about deliberate trouble?

Everyone stared at Xu Mang, very curious about his true identity.

however

The professor looked a little calm, looked at Xu Mang, and asked in a low voice, "Xu Mang, who is reunited?"

Xu Mang: Σ('д′*ノ)ノ

This...

How do you know this?

Could it be that the professor has the same superpowers as Xiaoman's mother?

Foresee?

"Hmm!"

"Professor, I'm Xu Mang. Xu Mang shrunk his neck and responded in the same whisper: "If you are a little bored, come and listen, by the way, feel the teaching quality of Qingda, and study hard." ”

The professor smiled: "I didn't expect it to be you, yesterday I heard the professor of the physics department say that you audited the class of the first-year theoretical physics major, and by the way, you made the students autistic, why do you still want to make the doctoral students autistic?"

Xu Mang: Embarrassed

They are already autistic.

"Ahem!"

"This is Xu Mang, who is Fuda. The professor introduced to his students, "I'm sure you've heard more or less about him, and one of his papers, "The Theory of Electron-Proton Synergy," was on the cover of Nature. ”

Words fall,

It caused an uproar.

Xu Mang?

He... How did he get in Qingda?

Obviously,

Most people know Xu Mang's personal, but there is no way that his movements have been too big recently, and from time to time I can hear some rumors that there is a person named Xu Mang in Fuda, who is very, very awesome.

Since it's him,

That means that the idea of solving the problem is correct, but this guy is inevitably too bad, right? Deliberately concealing his identity and running over to beat us, no wonder it is rumored that he often does not behave, which is something that a person can do.

"Xu Mang?"

"Are you a doctor?" asked one of the students curiously.

"It's not. Xu Mang smiled and said, "But I teach doctors." ”

“...”

“...”

“...”

It's embarrassing,

Shame on yourself!

At the end of class, these doctoral students left the classroom one after another, and when Xu Mang was about to leave, he was stopped by the professor.

"Xu Mang?"

"Is there time for noon?" the professor asked.

"Yes. ”

"Please have a meal at noon and talk together by the way. The professor said.

"Oh..."

"It's my pleasure, Professor. ”

...

midday

Tsingda staff canteen.

The food here is slightly better than outside, not only is the price low, but also the taste is good, Xu Mang took a little food casually, and then sat in front of the professor.

"Why are you at Qing University?" the professor asked curiously.

"National Collegiate Mathematics Competition. Xu Mang said: "I am the leading teacher. ”

“...”

"You're not a player?"

"Escorted. ”

Hearing Xu Mang's words, the professor smiled: "It's right to escort, if you compete, what will others do?"

"Xu Mang. ”

"Since you are so talented in mathematics, are you working on a mathematical problem?" the professor asked.

Xu Mang shook his head: "I'm interested in math... I'm not very interested, and the reason why I studied mathematics is because physics requires mathematics... I majored in theoretical physics. ”

"What?"

"You're not interested in math?" the professor looked at him in surprise, a person who is not interested in math has learned math to such a high level, this is a bit insulting, what about those who are interested in math?

Xu Mang nodded: "I was forced to learn mathematics..."

The professor smiled wryly, the first time he heard that he was forced to study mathematics, he learned to crush the level of a doctoral student.

Hell...

soon

After lunch, Xu Mang said goodbye to the professor, and just after leaving the restaurant, he received a call from Xiao Man.

"Hello?"

"Stupid!" Yang Xiaoman said, "Where is it?"

"Me?"

"Just finished lunch with the professor who taught the PhD. Xu Mang replied honestly, "What's wrong?"

"What!"

"Have you eaten?" Yang Xiaoman said angrily: "I waited a morning just to have lunch with you, and you actually told me that you had eaten?

Oops!

I forgot!

Xu Mang suddenly realized, no wonder when he had lunch, he always felt panicked, it turned out that he had forgotten Xiaoman.

"Huh?"

"I'm hungry again?" Xu Mang pretended to be surprised and said, "Aren't you strange, I just had lunch, and I didn't eat enough, uh... Hey, where are you?"

“...”

"Idiot!" Yang Xiaoman said angrily, "Of course I'm in the arena." ”

"Wait for me!"

Words fall,

Xu Mang went to the competition venue.

...

"Oops..."

"Don't be angry. Xu Mang looked at Yang Xiaoman's sulky appearance, and felt very funny, she used to be cold to death, but now she often plays tricks on you, and is willful from time to time.

If you can rewind once in your life, will you have a chemical reaction with Xiaoman again?

Fear... I will still buy the meat buns of that family, I will still appear at that point in time, I will still aim at Xiaoman's head, and I will still provoke her in class.

"What are you thinking?" Yang Xiaoman glanced at it and found that Xu Mang had been staring at him, and suddenly his pretty face flushed: "I don't have anything to do in the afternoon anyway... You just hold me and watch slowly, there are too many people now... I'm a little embarrassed, old lady. ”

Xu Mang: Embarrassed

"I was thinking about what choices I would make if there was a time machine in the world that everyone could use once. Xu Mang said.

"Humph!"

"You must regret knowing me, right?" Yang Xiaoman said disdainfully: "Go back to the past timeline and choose to be a passerby with me, right, tell you that there is no door, there is really this time machine, I will... I'll just smash it!"

Xu Mang shook his head and said seriously: "I think I still can't escape the law of fate, who made me love to eat that steamed bun." ”

Speaking of steamed buns,

Yang Xiaoman thought of the scene when he just reported to school that day, and spent an hour dressing himself up beautifully, but as a result, there were unforeseen circumstances, and people had good and bad luck, and he was actually topped with buns.

"You still have the face!" Yang Xiaoman glared at Xu Mang: "I spent an hour in the morning and was ruined by your bun." ”

Xu Mang was very helpless, and asked cautiously: "Aren't you going to my house for the Chinese New Year this year, what... Let's reminisce about the classics?"

“？？？”

"What do you mean?" Yang Xiaoman asked curiously, "What classic?"

"Feel the mood at the beginning. Xu Mang smiled and said, "I'm afraid you forgot." ”

Yang Xiaoman is so angry, this experience is a big stain on his life, he still wants to amplify it infinitely, what do you think?

"Get out!"

Words fall,

Yang Xiaoman suddenly thought of something, and asked in a squeaky voice, "Alas... Will your family recognize me?"

Xu Mang frowned and asked seriously, "Do you know how to cook?"

Xiao Man shook his head.

"Do you know how to do laundry?"

Xiao Man shook his head.

"Do you do housework?"

Xiao Man shook his head.

"Then you're finished. Xu Mang said seriously: "I won't know anything, it's hard for my mother to recognize you as a daughter-in-law." ”

Yang Xiaoman: (# ̄~ ̄#)

however

Xu Mang never expected that he was cheap for a while, and almost hospitalized his father-in-law.
