The next second, the impatience on her face disappeared, replaced by the meticulous seriousness.

It's easier said than done. Qin Luo's data is not only a summary of wrong knowledge, but also a method of solving problems and ideas

The most terrible thing is that every knowledge point can be made in three or more ways, and it is easy to understand.

The more she saw Lin Shanshan, the more frightened she was. In the end, she did not give out a exclamation: "can this problem be solved in this way?"

If it wasn't for fear of scaring you, I could use ten! Qin Luo's faint smile was full of complacency.

"Diddidi ~" at this moment, the clock made a short ring. Two hours. It's time.

It was not until this time that Lin Shanshan came to her senses.

"Two more hours!" Lin Shanshan said without raising her head.

Two hours? Are you my computer? How long do you want to go?

"Double the price per class." Aware of Qin Luo's strangeness, Lin Shanshan added.

Double

In other words, a class of 400? Scary!

"No time." Qin Luo said and opened the door.

One minute, two minutes After several minutes, Lin Shanshan didn't make any noise!

Miscalculation, miscalculation, Qin Luo heart is dripping blood.

Lin Shanshan was silent in the room, which was totally different from his script.

What about the third place of care? It's not a bad deal? How can I ask the price once and not?

“……” Lin Shanshan clenched her teeth. It was the first time in a long time that someone refused her, and it was repeated. Isn't learning better? What's the big deal, huh!

At the door, Qin Luo refused Yang Peishan's invitation to stay for dinner and opened the door.

"Wait a minute."

"Ms. Yang?"

Yang Peishan took out a bunch of keys without expression and put them in front of Qin Luo. "This is the key to the room. Come here when you are free."

Key?

Cough, is this really a mother?

This problem is quite serious, OK!

"I'm afraid that's not good."

"There are more than a dozen cameras installed in the house." Yang Peishan shrugged her shoulders and said calmly, "of course, if you feel that you have violated your privacy, you can bring it up to me."

Ha ha

More than a dozen monitoring, but also said so indifferent.

Lin Shanshan's mother is more ferocious than a great beast.

Yanjing University, the most ranked university in China, is the dream palace of countless Chinese students, the Holy Land in the minds of parents and the goal of teachers.

Wang Xuecai, Professor of Yanjing University, academician of Chinese National Academy of Sciences, and a big bull in mathematical circles, once won the "Hua Luogeng Award" known as the Huaxia fields award.

He is one of the most outstanding mathematicians in China.

At the moment, on his desk, there is an answer paper and hundreds of drafts.

It records the process of Zhou's conjecture.

It has been two days since I got this answer paper. In these two days, Wang Xuecai hardly closed his eyes.

Hundreds of scribbles and dozens of used pencil leads were his answers.

At the moment, Wang Xuecai's face was flushed. His eyes were full of blood, and his whole body was shaking.

"From today on, Zhou Haizhong's name will be recorded in the history of mathematics!"

"Zhou's conjecture has finally been proved! It will be sublimated from conjecture to theorem! "

"Spare the car, I'm going to see Zhou Haizhong!"
