At five o'clock, the bell rang.

The professor just finished writing the last sentence on the blackboard, walked to the podium and clicked the mouse, and projected the ppt to the last page - homework.

Inhale the bottom.

He stopped breathing for a while, smiled, and lit the mouse again.

There is also the next page of homework.

“…”

"I'm irritated."

The boy sitting in front of Xie Lan was named Wei Dongkuo, who was frantically flirting with notes, without the style of being the top ten in science. He spoke in a strange accent: "You can start two chapters in one afternoon? My claws are trembling."

Xie Lan was still writing the last notes on the iPad, and the pen holder almost made a afterimage.

He discovered that Wei Dongkuo always likes to use "chicken" to enhance his tone, just like the "Just Nima" that Che Ziming taught him back then. But the pronunciation of this word is more difficult and the language feels more elegant and smooth, making people unable to help but want to learn.

So he read it in a low voice: "I'll start two chapters in one afternoon..."

Unexpectedly, Wei Dongkuo heard it and turned his head, "Lan Shen, do you learn from me? Are you interested in our hometown dialect? Do you have time to show me more?"

Xie Lan looked up helplessly, "Can you shout a famous name?"

The other party laughed a few times, "My conscience does not allow me to insult the divine nature."

“…”

I don’t know who founded this name. It has only been two weeks since the official school started and has spread throughout the mathematics department.

What's outrageous is that there are several boys in the department this year who are not distinguished from "l" and "n". The heroic "male god!" made Xie Lan want to escape on the spot in public.

Xie Lan lowered her head speechlessly and continued to make up for the notes. Wei Dongkuo came over and said, "Let me see what Lan Shen's notes look like... Damn!"

The one next to him immediately turned his head, "I'll take a look, too!"

The screen is full of smooth English, and it is mixed with mathematical symbols bit by bit, elegant and elegant. Most people can't understand how to practice writing English, so Wei Dongkuo reacted for a long time, "I thought you wrote notes in Arabic. Is this Ingres?"

Xie Lan nodded, "The teacher speaks too fast, I... can't keep up with my Chinese characters."

It's also very ashamed to say that he used to take notes in Chinese for two years in high school. Although he wrote slowly than others, he persisted. Unexpectedly, he still failed in front of Professor T's Great Devil.

"Worship!" The boy next to Wei Dongkuo shook his head and sighed, "Although I can't understand this font, it can be fooled and has a divine character."

"Is that right?" Wei Dongkuo hurriedly said, "Shen Lan, you teach me English calligraphy, I teach you how to talk about chickens, how about it? The one you just now, you didn't have enough sounds. This word is not my hometown dialect. I have learned it from others for a long time and can be taught to you."

Xie Lan refused mercilessly, "Thank you, I already know. Chicken."

Wei Dongkuo almost turned over with laughter, and even the girls in front were laughing.

Xie Lan was a little embarrassed and quickly packed up his things and pulled his schoolbag and left.

Wei Dongkuo was one of his roommates who was originally arranged. Although Xie Lan rarely returned to the dormitory after military training, he still had a good relationship with this familiar roommate.

Dou Sheng had class in the evening, so he sent his boyfriend to class and wrote the math homework he had just done in the library.

The phone was silent, but the screen kept popping up because the messages kept popping up. He picked it up and glanced at it after solving two questions.

Various notes were taken in the group, and the group of people cried for help were caught in despair.

-What about the number ring q4?

-/photo

-Don't you, you've been wiped

-I realized that I couldn't finish writing and it was too late to take a photo

- This teacher is really awesome in shaping the blackboard

-Bald head, our teachers really like to write on the blackboard...

- As we all know, ppt is only used to assign homework

-Has anyone ever recorded the mysterious q4??

-Guo Zi has the upper half, Kuo Ye has the lower half, but a few lines are missing

Xie Lan poked the iPad casually, took the corresponding part and posted it into the group.

The group immediately exploded again.

-Lan Shen!!(Zhen Sheng!)

-Lan Shen appears!

-Congratulations on attracting the attention of God Lan

- and successfully unlocked Lan Shen's help

-I was so moved that I couldn't understand the mysterious language on the screen. The only two lines of mathematical formulas I could understand happened to be what I needed. Who knows this kind of natural fate? I am locked by the Lan Shen.

The library was brightly lit, and the two large long tables were filled with people. The college students lowered their heads and studied with concentration and nervousness.

This quiet fryer group seems particularly inappropriate compared to the surrounding environment.

Xie Lan put down his phone speechlessly and continued to do his homework. But the group was still popping up, and the space was small, and the news was still clamoring in his aftermath.

-Does Mr. Xie Lan still have q6 notes?

-Same request

-q7 I want it too

-q7 I have, do I have the number domain q3?

-Crazy Ait, help @Xie Lan_em

Are these people serious?

Xie Lan had to export one note and send it to the group. In fact, all the previous notes were still in Chinese. He collapsed and changed to English when he couldn't keep up. The questions asked in the group just now all had Chinese versions.

But the Chinese version...

-??

-This word??

-I am stupid, the fourth line of q6, what is the pxq? Gu Gen?

-Is there a tongue...

-Why would I ask if the tongue is...?

Not finished.

Xie Lan had no choice but to put down his pen, picked up his phone and replied: "There is a heavy root."

-?

-?

-...

-It's hard for me to imagine...

-I also……

Xie Lan patiently explained: "I can't copy it all, I'll write it up. That 'tongue' is a simplified version of the 'heavy', and a little details are omitted."

-???

-...is it

-Billion Dot Details

-I laughed and dazzled

-I'm so hard that I can't hold back my laughter in the study room until I pinch my thighs

-Redefine "Simplified Chinese"

Xie Lan looked at the screen that was quickly brushing down, and was a little powerless, so he simply answered a few more questions that everyone could not see clearly.

-What is "Day#or"?

-Complex Domain

-Where is the "large-style knife angle"?

-Factorization

-Where is the "multi-worker"?

-...I think about it

Xie Lan settled for a few seconds and replied: "Polynomial."
