God-level Xueba system upgrades 999 seconds

"Qin Luo!" Li Wei was furious. Someone dared to laugh out loud in his self-study class, which didn't treat him like a human being.

"Ms. Li, I'm going to the library." Before Li Wei could finish speaking, Qin Luo had already rushed out of the classroom.

Li Wei?You used to ignore me, but now I make you unable to climb high.

library!
Li Wei was stunned. As the head teacher, he knew the habits of every student. If Qin Luo could go to the library, he would immediately jump off the second floor.

"What are you looking at! Go to self-study!" Li Wei turned around and scolded, then ran out in a hurry.

Alas, it's not easy to be a homeroom teacher, eating the public's food and worrying about the mother's heart.Not only to ensure teaching, but also to ensure the safety of students.

What's the matter with this girl.

Beishan No. [-] Middle School is not big, covering an area of ​​only a few hundred acres, but the library here is the largest in Beishan City, with the largest collection of books.

Even more than many university books.

The reason is very simple, because Zhou Haizhong, a well-known mathematician in the country and the director of the National Library of China, went out from here!

Relying on his relationship, Beishan No. [-] Middle School has the largest collection of books in Beishan City.

It was already eight o'clock, looking at the brightly lit library, Qin Luo felt strange in his heart.

As the famous crane tail, he hasn't been to this place for a long time.

Pulling himself together, Qin Luo stepped into the library.

"Mission starts: time limit of ten hours, progress 0/10."

As soon as he stepped into the door of the library, the system's notification sound came as promised.

"He really went in?" Li Wei, who followed closely, almost dropped his eyes.

"No, he must have slipped away in the name of reading!"

As the head teacher of the third class of high school, he knows the tricks of the students like the back of his hand, and he has seen a lot of people like Qin Luo.

-

Looking at the rows of bookshelves in front of him, Qin Luo felt a dry mouth.

These books are like gold mines, waiting for Qin Luo to mine them.

Licking his lips, Qin Luo, who was still hungry, rushed to the bookshelf.

"Student, where are the books about mathematics?" Helplessly, Qin Luo turned to the classmate beside him for help.

The other party seemed to have not heard Qin Luo's words, and muttered in his mouth: "Functions and limits..."

"...Meet a bully." Qin Luo's mouth twitched.

Going around and wandering around in the library for a long time, I finally came to the mathematical classification bookshelf.

Just as he was about to pull out a book to read, suddenly Qin Luo's eyes blurred, and a series of numerical values ​​appeared in front of Qin Luo's eyes.

"Goldbach's conjecture: 500 points of mastery."

"Functions and limits: 20 points of mastery."

"Expansion and analysis of trigonometric functions: 10 points of mastery."

"..."

Originally, Qin Luo thought that a book was worth five points at most, but now it seems that the value of Xueba increases with the increase of value.

Thinking of this, Qin Luo licked his lips, showing wolf-like eyes.

Without any hesitation, Qin Luo picked up the most famous book in mathematics, "Goldbach's Conjecture", and read it carefully.

"This kid really came here to waste time!" Li Wei who hurried over saw Qin Luo's movements, and his teeth itched instantly with anger.

Can Qin Luo understand Goldbach's conjecture?Not to mention a high school student, even a college student, or even a graduate student or a Ph.D., can't understand it.
