Song Yi is in his fifties and has been in charge of grading the college entrance examination for many years.

He casually glanced at the scroll on the screen, frowned, didn't understand?

Lean down and look again.

This examinee's words reveal a sense of logical and meticulous care.

It's not like piecing together a rat to score.

However...... Song Yi has been a teacher for decades, and he has never seen this kind of solution.

"Half of the branches."

Zhang Ling: "That's not very good, right? ”

Every score has the potential to determine the candidate's future.

Isn't it irresponsible to them to be so casual?

Zhang Ling's attitude insisted, and Song Yi waved his hand, "Then convene experts, and let's discuss this volume." ”

Ten minutes later.

The five teachers sat in front of the computer, confused and confused.

"You see?"

"I can read words, count?"

“……”

One of the teachers moved the mouse and looked at the topic in front of him, and his eyes widened.

"Lao Liu, why are you staring at you, you want to eat people?"

Lao Liu touched his eyes to make sure that his eyes were not wrong, and turned the computer to them by himself: "Look at it yourself." ”

"All, all right?!"

Are you kidding!

In previous years, it was not without high scores in physics, but this year's question is Pang Hanzhi!

He made the question, and the basic average score was good if it passed the passing line!

There is a seventy or eighty exam!

This, this is actually a perfect score in front of it?!

The group was silent.

"The front is all right, and the last question should not be nonsense."

"You're right."

Song Yi added, "The key now is that as experts, you can't understand it, who can understand it?" ”

"I heard that Wu Lao is in school today."

"Old Wu? Academician Wu Junlei?! ”

"Yes."

"No, no, it's just a college entrance examination question, so it's too trivial to bother his old man."

"So you have a way? You said! ”

Those who opposed it just now were dumbfounded.

Five miles, three in favor, one against and one abstention.

Simply, I copied the title and went to Wu Lao to take a look.

Of course, it is not excluded that they admire Mr. Wu and want to visit the old professor.

"Knock knock~"

Wu Junlei is nearly 70 years old, and he is still in good spirits, and when the experts knocked on the door and entered, he was still sitting on the table calculating the problem.

"Hello, Professor Wu."

The more respectable the old professor, the more approachable he is.

Professor Wu listened to their intentions, and the old hand lifted his gold-rimmed glasses, and smiled kindly, "College entrance examination questions?" Show me. ”

The old professor took the paper and squinted at it.

At first glance, he still had a smile on his face, and the more he looked down, his whole heart jumped.

He looked at the calculation process over and over again, and his old eyes lit up with excitement, and he couldn't wait to draw a pen and calculate it on the calculation paper.

“…… I see. ”

"How can it be counted like that?"

The old professor's hand holding the pen trembled, and after he finished calculating the whole question, he suddenly got up to get the notebook on the opposite table, bent down and pulled it over, and began to calculate again.

"Yes, yes, that's it!"

The experts sitting on the sofa looked at each other.

At the same time, an incredible thought came to my mind: Are all the steps to solve this problem correct?

Moreover, it also gave the old professor new inspiration?!

Wouldn't it?!

You know, the person in front of you is a national treasure.

He is basically present in the design of large-scale engineering activities in China.

And the one who solved the problem was just a high school student.
