After the Villain is Reborn, I Hold My Golden Thigh

Lan Yin returned to the classroom and sat in her seat.

A few seconds later, Teacher Yu Zhen, who taught the class for the students, also walked into the class.

Half a minute ago, Teacher Yu Zhen was still shocked by what she had just heard outside the door.

But when she was in the class, she was able to instantly restrain the emotions that she should not bring into the classroom as a teacher.

On the podium, Teacher Yu Zhen opened the lesson preparation materials and led the students to class.

In the back row of the classroom, Lan Yin was still not listening.

As for mathematics, after she has learned the steps to complicate simple problems, Lan Yin doesn't even need to flip through the textbook——

She put the math textbook in front of her as a display, and then Lan Yin suddenly remembered what the math professor just said.

He said that the world-class problem he solved was a problem created by a famous mathematician in Europe?

As a native of China more than 100 years later, Lan Yin could not see that her country lags behind others in mathematics.

So she took out her mobile phone from the pocket of the gray-pink casual suit she wore to school today, and with the cover of the textbook, her fingers 'beat' on the mobile phone quickly.

In a short time, she called out the mathematical problems left by the world today, which were displayed in the world's authoritative mathematics forum.

There were four questions in total, three of which were written by mathematicians in Europe, and one question was written by a small country in China's neighboring country.

However, this question looks like a tiger following the trend, and it is very similar to one of the three questions in the European country.

Among the three questions, one of them was posed by a European mathematician more than ten years ago. From the title Lan Yin, we can see that this question is the most difficult of the three questions.

There are also two questions that were posed by European mathematicians six years ago and one year ago.

Among them, the question six years ago was the easiest. Lan Yin took a look at the question type and got the answer after two seconds.

I want to recall the question that Professor Mu said just now, which was posed by a mathematician in European countries a few years ago.

Lan Yin was still interested in solving problems.

Since the status of mathematics in China is to be improved, it is not enough just to solve a problem.

Lan Yin gently swiped her finger to create a new post in this authoritative math forum post.

Then write down the problem solving process and answers of the three questions except the one solved by Professor Mu.

At the end of solving the problem, Lan Yin did not forget to leave a new 'problem'.

She wants to announce to the world that in mathematics, the most difficult problem comes from Hua Guo——

Of course, the difficulty of this question is only relative to the three questions she has solved at the moment.

In fact, in Lan Yin's view, there is still no difficulty.

In her time, it was only the scope of examinations for junior high school students.

But even so, even if the formula she left for Professor Mu was made public, it would not be possible in ten or eight years to solve this problem with the mathematical level of today's mathematicians.

At the end of the post, Lan Yin did not forget to sign her name, she left a few words——

China.

--blue.

At the same time that Lanyin solved three world-class mathematical problems and released them.

Professor Mullin, who temporarily borrowed the office of the principal of Ningcheng No. 1 Middle School, couldn't wait to publish the problem he solved!

Not long after Professor Mullin sent it out, he received a lot of attention.

Even an honorary mathematician from the highest university in China found his contact information and called directly——

"Professor Mullin, I'm Yang Xian from Imperial College. I just saw the solutions you posted. You are the blue one? How did you solve those problems? What inspiration do you have?"
