"In this problem, let the function x satisfy f... That's right, that's the idea,"

"This title draws a diagonal auxiliary line,..."

"The tangent coordinates of this problem are unknown, so the tangent coordinates should be set first, and then solved. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

This question is simple, assuming that plane A is x,...。 ”

“……。 ”

Zhou Xing's eyes are hot, he writes non-stop, after increasing his IQ by 25 points, his brain becomes flexible, his thinking is clear, he draws inferences from one another, and doing mathematical problems is like opening and hanging, even if the problem is complex, he can always think of the corresponding solution ideas and apply the correct formula to solve it.

Solving problems is like playing a game, conquering one level after another to obtain achievements, Zhou Xing can't help but immerse himself in it, and can't extricate himself.

The questions were solved one by one, and time flew by bit by bit, and before I knew it, it was already late at night.

With a "crunch", the door suddenly opened, and Ye Huilan walked into the room with a porcelain bowl.

In front of his eyes, Zhou Xingzheng was sitting at the desk, concentrating on writing, and there were a bunch of exercise papers stacked next to the desktop, densely filled with answers.

"Xiao Xing, don't do it, drink this bowl of chicken soup, and go to bed quickly!" Ye Huilan slowly walked behind Zhou Xing and put the porcelain bowl on the desk:

Zhou Xing looked up at the electronic clock on the wall, and before he knew it, it was already 11.30 minutes.

"Well, I'll go to rest when I'm done with the practice papers. Zhou Xing turned his head:

After speaking, Zhou Xing consciously stopped doing the question, put down the pen, picked up the porcelain bowl with both hands, and drank the chicken soup in one go.

These days, Zhou Xing has become accustomed to the soup that Ye Huilan cooks for him every night, as well as the "nagging" urging him to rest early.

"Well, don't stay up too late, you will lose more than you get when you get sick. Ye Huilan persuaded distressedly:

"Mom, I know, you go to sleep first! This exercise paper will be completed in half an hour. Zhou Xing handed the porcelain bowl to Ye Huilan and nodded:

After speaking, Zhou Xing turned his head and plunged back into the sea of questions.

Seeing Zhou Xing racing against time and studying seriously, Ye Huilan was distressed and relieved, no longer bothered Zhou Xing, took the empty bowl, and silently exited the room.

Before I knew it, another half an hour passed,

As soon as 12 o'clock arrives, the system's forced learning state disappears.

After finishing the last question, Zhou Xing exhaled a heavy breath of turbidity, put down the pen in his hand and stopped doing the question.

For more than five hours, I did the questions of seven practice papers, and the speed was okay, but I don't know how much accuracy I can have.

Zhou Xing took out the answers to the practice test paper and began to check, outlining and marking the questions one by one.

"The first paper is wrong with two questions, the second paper is wrong with four questions, and the third paper is three questions,... , I'm lucky to get a full score in the test, haha!" After checking the papers, Zhou Xing laughed happily:

After the system added 25 IQ points to him, Zhou Xing felt very good about himself, his head became smarter, his memory, logical thinking, and all of them were strengthened, which made him feel that the difficult topics were significantly reduced, although it was not as perverted as the "excellent wisdom" blessing of 120 IQ, and he could master all the knowledge in three years of high school in three days, but his memory, comprehension ability, and problem-solving ability have been significantly improved.

If the mock test is conducted now, Zhou Xing is sure that the lost score will be controlled within 100 points.

The probability of completing the first place in the college entrance examination has increased greatly, and now what is lacking is time, Zhou Xing needs to do more questions, be familiar with various question types, reduce mistakes, and the system library can just meet the requirements of increasing learning time.

Zhou Xing finished washing, changed into pajamas, and couldn't wait to lie down on the bed.

"System, send me to the library!" Zhou Xing's eyes closed slightly, and he instructed the system, saying:

"Okay, host!"

Immediately, Zhou Xing's spirit was in a trance, and after waking up, he was already in the vast library with a vast sea of books.

"System, help me search for high school math study books, and get a set of tables and chairs, I want to do the questions in the library!" Zhou Xing continued to instruct:

"Yes!" the system responds with a short but powerful response:

Immediately, a set of black desks and chairs appeared in front of Zhou Xing, with a stack of white scratch paper and a black pen on the desk, and tall bookshelves on both sides of the desk, on which were rows of high school mathematics study question books: "College Entrance Examination Mathematics Real Questions", "Huang Gang Question Dictionary", "High School Mathematics", "High School Mathematics All-round",... , variety, all-encompassing.

Zhou Xing took out a workbook of "1,000 Must-Do Questions for College Entrance Examination Mathematics" from the bookshelf, sat down at the desk and began to do the questions.

I don't know if it's an illusion, or if it's supposed to be like this, after opening the exercise book, Zhou Xing's original tiredness disappeared, and the whole person became excited, and he threw himself into the sea of questions energetically.

Zhou Xing concentrated on the problem and kept writing.

――――――――

The stars turn, day and night alternate, and the night passes in a blink of an eye.

At seven o'clock, the sun scorched hot, and the sun shone obliquely into the room through the window, falling on the head of the bed, and shining on Zhou Xing's face.

Zhou Xing's eyes suddenly opened, he blinked, and woke up from his deep sleep energetically.

Last night, I spent almost all night in the library doing problems, and six or seven tenths of the thousands of math problems were completed, Zhou Xing had an illusion that it seemed like a dream, but he remembered the problems very deeply, and those problems were not done in vain.

After a night of serious mental testing, after waking up, Zhou Xing did not feel sleepy, but was full of energy, which was very magical.

"System, I did so many exercises last night, but now I'm not sleepy, don't I need to rest?" Zhou Xing asked curiously:

"Host, after opening the library, it will automatically guide you into deep sleep mode!" the system responded:

"System, what is the ratio of time to the library, and why is the ratio of the library to real time 5:1?" Zhou Xing frowned and asked puzzledly:

"The host, stationed in the library, the system will be configured according to the host permission level: time ratio, time ratio definition is based on: library transmission information speed, host neuron reception efficiency, information transformation speed,... to adjust the definition!" the system replied:

Zhou Xing frowned, the more he listened, the more confused he became, and he couldn't understand the principle of the system's definition of the time ratio for the library.

It's time for a new day to start and get ready for school.

Yesterday, because of the "system" trouble, he rejected Ai Xiaoqing's invitation, was Tang Xin angry at that time? I hope I can take time to explain today.

Giving up the idea of continuing to explore the library, Zhou Xing sat up, stretched his comfortable waist, rolled over and walked out of bed, put on his slippers, and walked to the toilet.
