Black Technology Incubation System

[Trigger side mission [-]: Complete Lou Jianyue's test.

Reward: Points +100, Concentration Potion x 2

Novice benefits: Focus time experience for 12 hours. ]

The system released the task in a timely manner.

As soon as Gu Xing heard this, he immediately took over the problem, and came without even looking at it: "Don't worry, I will solve the problem tomorrow morning."

Lou Jianyue didn't expect him to be so impatient, coughed dryly, took a sip of tea, and added: "First, you can't ask for help from outside, you have to solve it by yourself. Second, this problem was given by Professor Zhang Zhang of the math class. A typical problem in "Advanced Algebra", you need to find the formulas and theorems related to this problem. It is recommended that you read the book before doing the problem."

"Okay." Gu Xing nodded in agreement, his eyes swept over the topic.

"n-dimensional Euclidean space V", "positive semi-definite symmetric square matrix"... a bunch of inexplicable symbols and terms rushed to my face.

Well, the difficulty is a bit big.

Lou Jianyue saw that his expression was serious, not like a joke, and his tone softened a bit, explaining: "This path is prepared for those excellent seedlings who study mathematics, and it is required that they must fully master the freshman mathematics department when they transfer to a major. Knowledge, you will not be given the opportunity to make up lessons and retake it later. What's more, there are more preparations to be done in the two months of summer vacation, you must have the ability to quickly absorb and master knowledge."

"Brother Lou doesn't believe me?" Gu Xing asked with raised eyebrows, changing his previous frustration one by one.

Lou Jianyue shook his head: "I believe in your talent, but you are a person who sees the new and forgets the old. You will be interested in everything, but each interest will not last long."

So it is always not easy to fool someone who knows you too well.Gu Xingyi pretended to be sad: "I didn't expect Brother Lou to be so unreliable in his heart, you have to make it up to me."

"What do you want to do?" Lou Jianyue helped his forehead helplessly.

"Hee hee, do you have a PDF of "Advanced Algebra"? Send it to me." Gu Xingyi said with a smile if he could save some time.

"Yes, this website will be sent to you. There are paid electronic books and supporting exercises. At the same time, you can also find other teaching materials on it. Of course, I recommend you to go to the library." Lou Jianyue sent him a link .

Gu Xing thanked him happily, and couldn't wait to register on the website, buy the e-book, and download it on the tablet.

Now is the time when the interest is strong, so Gu Xingyi simply read from Chapter 1 directly.

[System, start the focused time experience. ]

[OK, I wish the host a pleasant experience, save enough points as soon as possible, and buy focus time! ]

"The discovery history of natural numbers 1, 2, 3, ... may be as old as human history. All natural numbers are recorded as N..."

Gu Xing saw the beginning and couldn't help but immerse himself in it. After reading it in one breath, he felt refreshed and extremely excited, as if the fog of his previous studies had been dispelled, and the gate of the new world was singing before his eyes. When it was opened, the operating law at the bottom of the world flickered, tempting him to pursue it.

Seeing Gu Xingyi's rare concentration, Lou Jianyue was also a little surprised. He didn't expect that when the waiter came to clean up the dishes, the boy was still reading a book, and even started to mutter to himself. Akira: "Yiyi, come back to your senses!"

"Ah?" Gu Xing raised his head in a daze, and Lou Jianyue seemed to see dense polynomials in his eyes.

"I'll take you back."

"Okay." Gu Xingyi felt that his mind and heart were attracted by the few wonderful proofs in front of him, like a starving ghost seeing delicacies, or a miser seeing gold and silver. Outsiders plunged into the ocean of mathematics.

Lou Jianyue saw that he promised without moving his buttocks, knowing that this person didn't listen to his words at all, so he held the person's free hand, led him to the dormitory, and pressed him on a chair.

Seeing Gu Xingyi raised his head in a daze looking for something, Lou Jianyue understood and handed over a pen and paper.This is great, Gu Xing used up a piece of paper in a short time, and threw the paper away in the next second, continuing his mathematical adventure.

Lou Jianyue picked up the waste paper, glanced at it, and it read: "First, if u is the unit root of nth order, then... then let... be the original unit root of nth order... then from the above knowledge... It can be obtained...and because |W| is the determinant of Vandermonde, which is not 0, so taking the determinant on both sides of the equation gives..."

At this time, what Gu Xingyi calculated was a sample problem.For beginners who are new to this door, they can solve it naturally without looking at the prompts, and their self-learning ability has reached Lou Jianyue's standard.

What's more, although Gu Xingyi has many bad deeds of liking the new and disliking the old, this time he was surprisingly serious and focused, even to the point of being obsessed.

Lou Jianyue looked at the young man who was studying mathematics under the desk lamp, his eyes softened. Perhaps Gu Xingyi was born to be in the field of mathematics, but he was too simple to learn before, so he was not interested?

Thinking of this, Lou Jianyue smiled and shook his head. This is a common excuse that Gu Xing used when he couldn't sit still and couldn't learn it. Now it seems that it is somewhat believable.

Gu Xingyi only came back to his senses when the sun was setting and the orange sunlight lazily crawled into the dormitory.

[Warning, the host's body energy is insufficient, the experience of concentration time is over, and the balance is six hours and twenty minutes. ]

[Host, are you okay? ]

[Fortunately... Fuck, this thing has great stamina! ]

Gu Xing rubbed his swollen and sore temples, feeling that someone had stuffed a balloon into his head, and someone kept pumping air into the balloon, as if he had been invaded by a swarm of bees, and his ears were buzzing.

"Come back to your senses?" Lou Jianyue rubbed his hair, and came over with a box of lunch, "Go to the cafeteria and get you a meal, and continue after eating."

Gu Xing was attracted by the aroma of the food early in the morning, and his mouth watered. Hearing this, he even took the boxed lunch and started to eat it.Lou Jianyue's heart trembled when he saw the voracious gobbling, and just hurriedly took a glass of water and handed it over: "Eat slowly, be careful not to choke."

"It's okay." Gu Xing swallowed a mouthful of rice, raised his head and said something in a hurry, then lowered his head and ate.

After a box of lunch was eaten, Gu Xingyi finally got rid of the feeling of hunger and panic before, and was half full, so he could rest and drink some water after all.

[System, will the experience of focusing on time consume my body's energy? ]

[That's right, the host needs to eat well, so as to supply the consumption of the body.Of course, with the system in place, the host will not be overly exhausted. ]

[That's good. ] As soon as Gu Xing was relieved, he didn't communicate much with the system, but he also saw that this system from the future said it would be obliterated on the surface, but in fact it was very soft and kind.What the system says is naturally credible.

"How do you feel about this book?" Lou Jianyue asked gently when he saw his mouth relax.

Gu Xing recalled it for a while, let alone, the products produced by the system must be high-quality products.The things seen in the focused time experience are still clear after leaving the state, and the things mastered are almost instinctive, and you can use them as you like.

So he said calmly: "It's great, it's very in-depth, and some solutions are amazing. I think advanced algebra is a maze, and the editor sprinkles feathers of reminders for us on the right path."

"Others say this book is obscure, but you like it." Lou Jianyue said with a smile, with admiration and anticipation already in his eyes.It was the first time he saw this level of concentration in Gu Xingyi, and he chose to stay because he was curious about how far he could do it.In the end, I spent an afternoon with the other party, witnessing Gu Xingyi's gods blocking and killing gods and Buddhas, and solving most of the advanced algebra books all the way, and I feel hearty at this moment.

Gu Xingyi touched his nose in embarrassment. In fact, he didn't like it much, and it was all thanks to the system.

After turning on the state of concentration, he followed like a demon, crazily loving algebraic formulas. Looking back afterwards, he was frightened and couldn't help but want to experience it for a while.

[System, your time-focused experience won't have any side effects, will it?Like addiction or something. ]

[Host!You are a slander, an insult to the system!Am I that illegal system!This state of concentration is called flow, and addiction to flow is as normal and harmless as human craving for sugar! ] The system said angrily.

[Okay, okay, I was wrong. ] Gu Xingyi hurriedly apologized, feeling ashamed that he used the heart of a villain to treat a gentleman's belly.

[Hmph, the host has to wait for an hour before continuing to experience it. It is recommended that the host take the time to rest.During this period, don't disturb the system's unilateral cold war. ]

After speaking, the system immediately went offline.No matter how much Gu Xingyi harassed him, he still couldn't get a response, and his temper was not small.

"Have you got an idea?" Lou Jianyue asked while seeing the confident look in his eyes, marveling at his talent for self-study.

Gu Xing touched the back of his head, but he didn't pretend to be modest: "It's sure."

"That's not urgent, just take a break. For research, the body is the capital, and only by combining work and rest can you go further." Not intending to persuade Gu Xingyi to leave, Lou Jianyue's tone changed, and he began to regard Gu Xingyi as a The younger generations pass on the experience.

"Like Brother Lou raising flowers for relaxation?" Remembering the colorful flowers on the balcony of Brother Lou's house, Gu Xing said with a smile, "Anyway, I'm planning to go this way, why don't you give me a few pots to raise?"

Lou Jianyue shook his head: "Don't mention the flowers, every time you come, most of the disasters will be eliminated. I want to give them to you, but it is sending sheep to the tiger's mouth."

The two chatted for nearly an hour, and Gu Xingyi's swollen and painful temples finally subsided, and his complexion looked better.Only then did Lou Jianyue let him go to continue his great work of solving problems.

The system went online on time, although his tone was cold (still sulking), but he was conscientious and pulled Gu Xingyi back to the obsessed state within minutes.

When it was nearly nine o'clock, Gu Xingyi finally sharpened his knife, and launched a charge against that difficult problem!

"First prove that for any α, β has...because...therefore..."

"It is known that S is an n-order semi-positive definite symmetric square matrix, then... (where S1...), and it is known that S1 is reversible, then..."

"When a1..., it can be transformed into..."

……

"Comfortable." The road was unimpeded, and Gu Xingyi saw the general direction from the time he wrote the pen, and the process of calculation was nothing more than repeating his own prophecy.When it was completely resolved, Gu Xing still felt a little regretful when he wrote the pen.

"Yes." Lou Jianyue's voice rang in his ears, and gusts of heat rushed to his ears, making Gu Xing unconsciously want to move away, and the temperature of that area even more subconsciously increased.

Lou Jianyue didn't realize Gu Xingyi's strangeness. He watched Gu Xingyi solve the problem all the way. Although it was an extremely simple problem, it aroused the enthusiasm in his heart. Watching Gu Xing watch him complete the answer: "This is the final exam question of the last mathematics and science class, and less than one tenth of the people solved it. It took you so much time to complete it, it is indeed the material."

[Congratulations to the host for completing Branch [-], the mission rewards have been distributed to the backpack. ] The system no longer pretended to be indifferent, and its tone was cheerful.

Gu Xingyi was originally curious about what the system backpack was and wanted to study it quickly, but was attracted by Lou Jianyue's next words, so he didn't have time to check the rewards.

"Yiyi, this summer vacation, you will publish three papers."

The author has something to say: Many symbols cannot be typed out in the process of solving mathematical problems, and the stupid author has read Professor Zhang Xianke's "Advanced Algebra" for a long time and still can't understand it, so all the problem-solving processes in the article are abbreviated and fabricated. Sorry for the inaccuracy.
