Chapter 1： Im serious about solving problems (1/2)

Beishan Fourth Middle School, mathematics class.

Li Wei's face was green, and he stared at Qin Luo straightly: ”Qin Luo, get up, tell me how to solve this problem?”

While talking, Li Wei casually wrote a mathematical equation on the blackboard.

He even dared to sleep in his class. He simply didn't know how to write dead words.

”It is known that the ellipse X-square+Y-square=1 and the straight line X-Y+B=0 intersect at two points PQ, and O is the origin of the coordinate. If OP is perpendicular to OQ, find the value of B and write the process.”

Qin Luo Juhua's face was stunned.

”The strongest Xueba system is on, and the progress is 99%...”

”The system was installed successfully.”

who? Who is talking? Qin Luo looked around.

”Dip, the host thinks hard, and gets 1 point of Mastery.”

system! At this moment, Qin Luo became excited. As an old bookworm of the 21st World, he was very familiar with the system.

This is a must for the protagonist, whoever gets him, without exception, has become a coaxing existence.

It’s just that Qin Luo didn’t expect that he actually got the system.

Thinking of this, Qin Luo couldn't help but speed up.

”Don't froze, do it quickly!”

”Do you think you are a genius, like Huang Zhen, can get full marks in class and sleep?”

Huang Zhen, the son of the dean of the fourth high school, from the moment he entered the fourth high school, he was the real pride of the sky. His academic performance has never been in the top three. Every time he takes the test, he is among the top ten in the city. Save thousands.

He has always been the sharpest weapon in Li Wei's mouth.

”Isn't it just a question? It's not that I don't know how to do it.” Qin Luo glanced at Li Wei smugly, and went straight to the podium.

Starting today, he is no longer an ordinary person, but a person with a system.

Picking up the chalk, Qin Luo suddenly got into trouble. Although he had a system, he didn't know how to use it.

”Ms. Li is one of the top ten mathematics teachers in the city. Even if I can't quite understand the questions he asked, he? Hehe, give him ten days, he can't do it right.” Huang Zhen pulled his eyes and swept lightly. Qin Luo glanced, his eyes full of disdain.
