Future Super Intelligent System

Time passed, and it was June 20th in a blink of an eye.

The exam dates for the three courses required by the task are June 23 for "Complex Variable Functions", June 25 for "Discrete Mathematics", and June 26 for "Probability".

There are 3 days left to take the "Complex Variable Function" test. Liu Fan went to the library for a long time in the morning, and in the afternoon he went to Mr. Liu who taught "Complex Variable Function" with the questions he had accumulated during this period.

When he came to the teacher's office, Liu Fan knocked on the door cautiously.

"Come in."

Liu Fan opened the door and walked in. There were only three male teachers in the office, and Liu Fan didn't know each other.

"Who are you looking for?" asked one of the teachers, who looked relatively young.

"Hello, teacher. I'm looking for Teacher Liu Weiliu."

"Ms. Liu should be in the store now." The other party said uncertainly, you can go to the store to have a look.

"In the shop?" Lin Fan looked confused, "What shop?"

"That Sichuan restaurant diagonally opposite the school gate." The other party explained, "Go over there and look for it."

"Okay, thank you teacher." Liu Fan glanced at the time, it was one o'clock in the afternoon, guessing that Teacher Liu might be eating there, so he quickened his pace and rushed to the school gate.

Diagonally opposite the school gate, there is only Liu Ji Sichuan Restaurant, which is easy to find.

"Hello, what do you want to eat?" A middle-aged woman greeted warmly as soon as she entered the door.

"Oh, that, I'm here to find someone." Liu Fan said as he scanned the store. The Sichuan restaurant is not big, with only a dozen tables in total. There are three tables of people eating now, but he didn't see Mr. Liu.

"Oh, who are you looking for? Is it from that table?" Auntie pointed to the big round table at the back and asked with a smile.

"I came to look for my teacher." Liu Fan smiled and took a good look at the people in the store. "I guess the teacher has left. I'll look elsewhere. I'm sorry."

Liu Fan turned around and was about to leave the Sichuan restaurant. He wanted to ask the class monitor for the teacher's phone number. At the same time, the aunt smiled and asked, "Are you here to see Teacher Liu?"

"Huh?" Liu Fan just turned around and immediately turned back, "Yeah, is Teacher Liu there?"

"Yes, wait a moment." The aunt motioned Liu Fan to sit down, walked to the back kitchen and shouted, "Old Liu, a student is looking for you."

"Oh~~~"

Liu Fan heard a response from someone inside, and after a short wait, a familiar face came out from the back kitchen wearing a chef's uniform.

"Liu... Teacher Liu?" Liu Fan couldn't recover for a long time when he saw Liu Wei's attire.

Liu Wei looked Liu Fan up and down, and after a while, two words came out, "Who are you?"

Liu Fan: "..."

"Cough cough cough." Liu Fan coughed twice in embarrassment, "Teacher, I am your student, Liu Fan, a junior majoring in Information and Computing Science."

"Oh oh oh, Liu... Fan..." It can be seen that Liu Wei is trying hard to remember the name, and after thinking about it for a long time, he probably gave up, "Well, what do you want from me?"

"That's right." Liu Fan didn't want to continue the awkward atmosphere, so he quickly changed the subject, "I don't know how to solve some questions, and I have difficulties understanding some knowledge points, so I would like to ask Teacher Liu to help me read them. "

"Oh?" Liu Wei wiped his hands carefully on the apron before taking Liu Fan's notebook and checking it.

Liu Wei looked back and forth for a minute or two, wondering if he subconsciously said, "Student Liu Fan, is your surname Zhang?"

"what?"

"Oh no." Liu Wei raised his head and smiled, "I mean, have you eaten yet?"

"No." Liu Fan responded instinctively, but immediately added, "But I'm not hungry."

It's really not that Liu Fan deliberately didn't eat lunch and pretended to work hard. He didn't have a big appetite, and sometimes he was too hungry when he was too busy, and then he simply waited until the next meal.

Liu Wei carefully placed Liu Fan's notebook on the dining table, waved his hands and said, "How can young people not eat, and besides, you won't be able to make it to the evening after you have finished talking about so many problems. That's all right, sit down, come on." Here we come, the teacher will make you two special dishes."

Liu Fan felt it was inappropriate and was thinking of how to decline, but Liu Wei went straight into the kitchen.

Seeing Liu Fan's uneasy look, the aunt came over with her warm smile, "Your teacher Liu is happy today, if you have nothing to do, you can have a light meal with the teacher."

"Are you the teacher's wife?" Liu Fan asked cautiously.

The aunt nodded and signaled Liu Fan to sit down. Liu Fan still felt that it was a bit inappropriate for him to do this, but the teacher had already gone in to cook, and the teacher's wife was here to persuade him.

After waiting for about twenty minutes, Liu Wei sat across from Liu Fan with Kung Pao Chicken, fried pork, shredded cabbage, pork head meat, and a plate of peanuts, "I'm afraid you won't cook hard dishes if you're hungry, eat some home-cooked food Bar."

"Teacher, you are too polite." Liu Fan sat up straight in trepidation, "I'm really embarrassed that you are doing this."

"What's so embarrassing about being old men?" Liu Wei waved his hand, "You are already an adult, are you still afraid of the teacher?"

"This is not living under the domination of the teacher since childhood..." Liu Fan whispered.

"Then be a teacher and force you to taste the teacher's craft." Liu Wei said here, and his wife came over with a case of cold beer.

"Can I drink it?"

"Let's have a little." Liu Fan's capacity for alcohol is actually not bad, but anyone who drinks often knows that if you can drink, you have to call yourself average, otherwise you will die at the wine table.

Liu Wei poured wine and ate two mouthfuls of food, but didn't talk about anything else, and directly took Liu Fan's notebook over, "Do you not understand these questions, or do you not know how to count them, or what?"

"I have classifications." Seeing that Liu Wei started to talk about the business, Liu Fan hurriedly got serious, "The main thing in the first part is that I did the calculations several times and the correct answer was not the same, and then there are basically problems in understanding in the next few pages. After that, I think the most difficult thing is that I can't even understand the title."

"Yeah." Liu Wei drank a glass of beer, and then remained silent for a while, "I probably know your situation, how about this, I will help you straighten out the basic knowledge points first, and then we will explain the topic for a deeper understanding, and finally we How do you feel about doing another review?"

"Listen to you, teacher." Liu Fan said respectfully.

"Okay, let me tell you about the problem of the complex sphere first. Many people think that this is a very basic thing, but in fact all the interesting things are in it...

Here you just mentioned the Cauchy integral formula, Xiao Liu, you have to remember that first you have to understand the high-order derivative of the analytic function...

Well, speaking of Laurent series, tell me what is its essence? By the way, he's still a Taylor series...

You said that mapping is your biggest difficulty now, so let's try to reverse it first, consider the application of mapping, and then talk about the principle...

..."

Not long after Liu Wei started lecturing to himself, Liu Fan immediately jumped out of the previous embarrassment and became extremely attentive to the lecture. What shocked Liu Fan was that Liu Wei's explanation was very simple and interesting, but Liu Fan Those who have taken Liu Wei's class have been taking the other party's class for a semester, but they have never found such a treasured teacher.

The two of them were teaching while eating like this, one was speaking carefully, the other was listening carefully, drinking beer and eating vegetables, and swiping at the test center to brush up the questions.

The business of Liu Ji Sichuan Restaurant is very good. Fortunately, there are other chefs in the back kitchen. Liu Wei and Liu Fan, the master and apprentice, have become a beautiful scenery in the Sichuan Restaurant today. An alcoholic who seems to be drunk is talking about mathematics that a group of college students who have studied advanced algebra can't understand...

Every college student who came in to eat had a group of black question mark faces rushing past.

WTF?

It was night in a blink of an eye, Liu Wei glanced at the clock on the wall, and covered the pen in his hand, "I remember the dormitory closes at eleven o'clock, right?"

"Yeah." Liu Fan nodded, and then he realized why he quickly glanced at his phone. It was already 10:15, "It's so late, but I haven't covered the rest of the knowledge yet."

Liu Fan frowned. He was indeed a little anxious. After all, after today, he only had two days to review.

Liu Wei closed the notebook and pushed it in front of Liu Fan, "Well, if you don't think it's going to change, come here tomorrow. I'm going to the office tomorrow, and you come to the office to find me."

"It doesn't change, what's there to change." Liu Fan said without hesitation.

Liu Wei looked at Liu Fan and smiled meaningfully, "You were uncomfortable at first."

"At first, uh..." Liu Fan smiled embarrassedly, "Teacher Liu, please decide, I will do whatever I want tomorrow, I'm sorry if it affects your business."

What Liu Fan said was the truth. He just realized that he might take up two days of the teacher's time, that is, two days of his money-making time.

"If you are really embarrassed, bring more classmates to eat with me in the future." Liu Wei naturally gave Liu Fan a step.

Liu Fan smiled, and then asked out the doubts in his heart, "By the way, Mr. Liu, why did you open a restaurant?"

"What's the reason for this? You can't have a job while you're alive." Liu Wei said after taking a sip of beer.

Liu Fan became more and more confused, and continued to ask, "Aren't you a university teacher, isn't that a job..."

"Cough, the university teacher is a joke." Liu Wei's expression changed as soon as he said that, as if he realized that he had lost his composure in front of the students, and hurriedly said vaguely, "It's not that, the university teacher is just a side job. Restaurants are my main business. Hahaha.”

Liu Fan is a sensitive person. You can see the change in Liu Wei's expression just now, and what Liu Wei said is so clear. Guan teacher's inner thoughts, so he pretended to be stupid and said, "Mr. Liu, don't tell me, you are much better at cooking than teaching. It is very delicious."

"Stinky boy!" Liu Wei pointed to Liu Fan, and then looked at the time, "Okay, go back to rest early today, I can't drive you after drinking, be careful on your own way."

"Okay, I'll walk back quickly." Liu Fan stuffed everything back into his schoolbag, and then said sincerely, "I'm really grateful to Teacher Liu today."

"Okay, let's go now." Liu Wei waved his hand while drinking, "My store opens at six in the morning, and you can come over anytime."

"Okay, goodbye, Mr. Liu, and goodbye, teacher's wife."

After Liu Fan left, Liu Wei's wife came to his side and put her hands on her husband's shoulders, "Are you happy today?"

"Cut." Liu Wei touched his wife's hand, "It's just a stinking brat before the exam."

His wife patted Liu Wei on the shoulder without making any unnecessary comments, but quietly started to clear the table.

Liu Wei took out a cigarette and lit it, looked at the dark university outside the store through the smoke, and said to himself, "It's getting dark...how can there be a sun..."
