Black Technology Incubation System

On the second day, Gu Xing went to Lou Jianyue's office as soon as he finished his class.

Lou Jianyue's research direction is number theory, so he took a position in the school's Institute of Basic Mathematics, with a small office.

At the beginning, two research monks were reading the thesis bitterly, and the draft paper was piled up on the table.The whiteboard next to it is filled with characters and several complex graphics.

Immersed in mathematics for the past few days, Gu Xing unconsciously stopped and looked at it for a while, only to feel very dizzy.At his level, don't even think about advanced number theory.

His pause was long enough for the other two to see him.

The more introverted senior pushed his glasses, smiled politely, and seemed to want to say hello, but before he could utter a word, his face blushed completely.

It was another senior who was always cheerful who broke the silence. He stood up with a smile and greeted him: "The junior is looking for the teacher again?"

"Senior, I have something to ask Teacher Lou." Gu Xingyi greeted him politely, and then explained his purpose.

"The teacher is not here now, you go in and wait for a while." The senior is also used to seeing Gu Xing come to the office from time to time, knowing that he has a close relationship with his teacher, and has no intention of stopping him.

So Gu Xingyi smoothly bypassed the screen and arrived at Jianyue's desk in the back building.

There are a few drafts scattered on his desk, a stack of folders on the left, an unclosed laptop on the right, and a bookshelf full of books behind him.The window just let in light from one side, and three pots of succulents were placed on the window sill.

Gu Xing looked around the office, and when he saw the computer that hadn't been turned off, he guessed that Brother Lou probably just went out for a while because of some trivial matters, and he would come back soon.So he also found a chair for hospitality and sat down, took out the tablet, and continued to work hard on the high-level math review.

It didn't take long before the two graduate students outside greeted each other.As soon as Gu Xing heard the voice, he raised his head, and saw Lou Jianyue striding forward in a shirt and trousers.

Lou Jianyue saw one by one sitting there concentrating on studying, and he felt a little relieved in his heart. After all, he had exhausted all his words to calm down this little boy, study for a while, and compare it with today's scene. It really feels like the flowers and plants that have been carefully cared for for several years have finally formed flower buds.

With this feeling, his tone was gentle: "I came so early, how long have you been waiting? Let me make you a cup of milk tea."

Gu Xingyi was a little flattered, and he never thought that such a serious person like Brother Lou would prepare milk tea powder in the office. He always thought that Brother Lou only drank freshly ground coffee.

Under Gu Xingyi's shocked gaze, Lou Jianyue rarely felt a little embarrassed, but at this time he explained it as if trying to cover up: "I saw that you were not very interested in coffee last time, so I studied it What do young people like to drink now, and I have prepared milk tea for you."

"Brother Lou, you're a young man too." Gu Xingyi didn't know whether to laugh or cry, but rolled his eyes, and said slyly, "I guess Brother Lou wanted to drink himself, and he still used me as an excuse."

Lou Jianyue couldn't beat him in this kind of matter, but he also had a way to cure this brat, so he pushed his glasses, turned around and walked to the desk, picked up a pen and wrote a series of books smoothly.

As soon as Gu Xing watched his pen go off like a dragon, his originally relaxed mood gradually lifted: "Brother Lou, please be sympathetic in your writing, I will go to the battlefield this weekend, and I can't read so many books!"

"Sharpening a gun in front of battle, it's okay to be unhappy," Lou Jianyue felt proud at the moment, "There is always enough whetstone."

Alas, Gu Xingyi took the paper in his hand with a sigh, what can he do, he should learn how to learn.

But after getting the paper, Gu Xingyi frowned involuntarily.Looking at the titles of "Introduction to Calculus and Mathematical Analysis" and "New Lectures on Mathematical Analysis", he asked with some hesitation: "Aren't these all works of mathematical analysis?"

Lou Jianyue turned his pen around. At this moment, he doesn't look like the big brother next door who teased him just now, but a senior in the academic world: "I don't answer the question, it's up to you to find the answer."

Alright, Brother Lou is about to start pretending.Gu Xing thanked him, took the paper and went to the library.

He often ate in the cafeteria, so he naturally took his meal card with him, swiped through the door with ease, and entered the library.

The east and west of the library are integrated, and the layout is elegant. As soon as you enter the library, you can see a few pieces of calligraphy, bringing out a bit of a bookish atmosphere.There are borrowing rooms on both sides. At a glance, you can see that the seats are almost full of people, and they are all students who are concentrating on preparing for the exam.

Although Gu Xingyi does not act normally, he is very curious and has a strong desire to explore everything in the world. He is also a person who never escapes because of hardships in his studies, so he is also a frequent visitor to the library.Even because of his extensive hobbies and thorough understanding of arts and sciences, he has a clear understanding of where and what kind of books are in the library.

However, the books proposed by Lou Jianyue were relatively professional, so he took out his mobile phone first, entered the library app, searched for the specific reading room and bookshelf, and then took the elevator upstairs, hugged a Stack of books, sitting at the desk.

There were hardly any vacant seats in the reading room. Gu Xingyi was lucky. He just found all the books when he saw a senior girl packing up her things and going to eat. She went over immediately and got a seat by the window.

He opened the book, inexplicably feeling a sense of heroism welling up from the bottom of his heart, and immediately called out the system: [How does the concentration potion work?Is it the same as focus time? ]

[Of course there is a difference. When concentrating on time, the host only has things to do in front of his mind, while the concentration potion is less useful. It is used to eliminate distracting thoughts, and the host will still be subject to certain external interference. ]

Then try the effect of the concentration potion first.Gu Xing thought to himself, read his backpack silently, and then took out a bottle of concentration potion. The potion itself was a small bottle. When it was taken out, the bottle cap had already been opened. And do.

After drinking the potion, Gu Xingyi also felt that he had focused a lot, and the book in front of him became even more cute, so he took the scratch paper and pen at hand, and started to study with great concentration.

However, it was already the end of the semester, and there were students everywhere in the library who were determined to study hard, and his state of devotion did not seem abrupt at all.

After reading only half of an "Introduction", the effect of the concentration potion gradually disappeared.Gu Xingyi gradually came out of the state of concentration, and was a little dizzy for a while, his shoulders were stiff, and his wrist was a little sore. While moving his right hand, he let his eyes go empty, wandering aimlessly.

The writing style of "Introduction" is friendly, as if the professor is explaining the knowledge points in front of him. Unfortunately, such words as "obviously" and "obviously" are not uncommon, which forced Gu Xing, who has proven obsessive-compulsive disorder, to write frequently.Now that I finally stopped writing, I'm not too tired, but more like a state of a sage's time.When the heart is content, everything is empty.

It was during this process of looking around that he and a classmate who was struggling to solve the problem happened to meet their eyes.

That classmate probably came when he was concentrating on brushing up the questions. After all, under normal conditions, he would never fail to notice such a hill.

Yes, this classmate's appearance is by no means like a frail scholar, but mighty and majestic, with well-developed muscles.When that big hand held the pen, it made people tremble with fear, for fear that this person would break the pen accidentally.The chair in the library made him feel aggrieved and unable to stretch out.

Where is this sports student from?As soon as Gu Xing thought about it in his heart, his eyes drifted to a piece of paper in front of him.

Wow, he is calculating points, and there is actually "Mathematical Analysis" next to him.It can't be seen that this guy is actually from the Department of Mathematics. When it comes to proof, he has conflicts with others. How can anyone dare to confront him head-on.

When he noticed what the other party was learning, it was obvious that the other party also knew what he was studying. As soon as his eyes met, he didn't know what signal this brother had received. Pushing it in front of Gu Xingyi, the voice was obviously soft on purpose: "Student, can you teach me this question?"

"Are you from the Department of Mathematics?" Gu Xing asked in a low voice as soon as he took the question.

This time, the brother was a little shy. He scratched the back of his head: "No, I'm from the Department of Chemistry. I'm a freshman now, and I'm studying computational chemistry with my teacher."

It turned out to be like this, no wonder I came here to study math.Gu Xingyi couldn't help but think of the narrow aisles and those fragile bottles and jars in the chemistry student's laboratory, and compared the figure of this brother, he suddenly felt sorry for their fate, but he still spoke quickly. Self-introduction: "My name is Gu Xingyi. I plan to transfer to the Department of Mathematics. I am currently a freshman."

"My name is Tu Liang, classmate Gu, do you know this question?" Tu Liang felt a little uneasy when he heard that the other party was planning to transfer to the Department of Mathematics, but since he had already asked the question, he was embarrassed to question the other party.

"Don't worry, it's a simple question for points." Gu Xingyi was already extremely talented in mathematics, and he studied so many questions with the help of the system, so he was naturally confident.

This confidence also infected Tu Liang. He leaned forward and listened carefully to Gu Xingyi's analysis.

"The first one is to find the limit. We use the simplest definition to find the limit. We need to properly enlarge the inequality. There are two key points. One is to change the implicit expression into an explicit expression, and the other is to make a reasonable choice. The score cannot be enlarged. For example, here, the Bernoulli inequality can be used, and then look at the mean value inequality, and the expansion of the quadratic term.” Except for the important point, Gu Xingyi is writing calculations most of the time and rarely speaks.

As Tu Liang listened, he had the feeling of seeing the sun through the clouds, and suddenly felt that the questions that had stumped him all morning were not really difficult problems, and the math was only mediocre.

"Hey, here, you can use L'Opidus by just changing it. 0/0, Luo is just playing around." Gu Xingyi solved the last problem, feeling comfortable, raised his head to meet a pair of glowing eyes, inexplicably I'm a bit cowardly, big brother, why do you look at me like that, although I'm gay, but I like boys who are fragrant and soft, not big brothers, big breasts are not good!Gu Xing's eyes moved up and down on Tu Liang's body for a while, feeling a little terrified.

At this moment, Tu Liang also regained his composure from mathematics. Seeing that it was getting late, he rubbed his hands together and said, "Master, I invite you to dinner."

When did I accept apprentices.Gu Xingyi's peach blossom eyes widened, he had a familiar personality, but he had never met such a guy who could climb smoothly!

Tu Liang didn't care about his shock, thighs, it's business to hug him quickly when he found it: "Master has taught me so much, it's right to call out to Master. What does Master want to eat at night? What time will you get up tomorrow? Do you need your apprentice to bring breakfast? When will we gather here for tutoring tomorrow?"

The master's name is nice, and the co-author wants to hire a tutor.Gu Xingyi didn't intend to refuse, after all, after explaining to him, what he had learned would be verified and reviewed, which would have many benefits: "You don't need to bring breakfast, and you will study here at [-] o'clock tomorrow afternoon."

Let Sun Jiu see what he was thinking about with breakfast, and he might be ready to marry himself off.Gu Xing looked at Tu Liang with complicated eyes when he thought of his gay friend who was sometimes enthusiastic about his love life.Just treat it as a tutor for others, and you don't need to show off what you have accepted as an apprentice.

"Okay." Tu Liang happily dragged the newly-baked master to the cafeteria.

After they left, Dong Yu listened for a long time on the opposite table and covered his face with a book. Finally, he put down the book and thought, "No wonder I suddenly learned mathematical analysis. It turned out that I was going to transfer to our department. Changing department, did you go through some back door?"

The author has something to say: the relationship between advanced mathematics and mathematical analysis is probably similar in content but different in depth.

Mathematical analysis focuses on analysis. It is an introduction to "analysis". It exercises mathematical thinking and proof ability, which is helpful for future learning of functionals and the like.

Advanced mathematics is much more simple, and it is for other students in science and engineering to learn basic mathematical tools. It is a subject that is enough to know what it is but not to know why.

Therefore, Tu Liang's academic score in the Department of Chemistry focuses on how to calculate the questions, as long as the calculation is fast, and Gu Xingyi is struggling to prove that
