From all-round academic master to chief scientist

At six o'clock in the afternoon, it was still the same study room.

Lin Xiao, who had a good meal, came to the study room with his proof process filled with more than 20 pieces of draft paper.

Teacher Xu Hongbing hasn't come yet. After all, it's still early. He probably went to eat. When Lin Xiao came over, he didn't see many people in the classroom.

At this time, he remembered the health capsules rewarded by the system, and silently said in his heart: "Extract [Health Capsules]."

Then, he felt something extra in his hand.

He was stunned, opened his palm, and saw a blue capsule appearing in his hand.

Suddenly, he felt incredible.

This thing actually appeared in his hand out of thin air?

Where did it come from?

Doesn't this violate the law of conservation of energy?

Lin Xiao was very shocked for a moment.

However, since the system was already there, it seemed pointless for him to dwell on this issue.

"But, is this a health capsule?"

Looking at this capsule, it can eradicate all external forces in the body, all external forces in the body, could it mean all diseases?

After all, they are called health capsules.

In addition, it can also bring certain strengthening to the body.

Can it make the body stronger?

After thinking for a while, he took out his cup from his schoolbag, put the capsule into his mouth, took a sip of water, and swallowed it.

He carefully felt the situation in his body and didn't notice any changes in his body. Maybe the capsule shell hadn't dissolved yet, and maybe it would still take some time for the medicine to take effect.

He breathed a sigh of relief. This is just science. Is there any medicine in the world that can work just by drinking it? It takes a while for the anesthetic to take effect.

He thought it was like the medicine in fantasy novels, and it would be effective after drinking it.

Then don’t think too much and just wait for it to take effect.

Then, he took out the scratch paper on which he wrote the proof process and read it from beginning to end again to check if there were any mistakes. Otherwise, he would be very embarrassed when the teacher found out later. .

However, after reading it from the beginning, he found no errors. Under the blessing of the immersion state, his thinking was quite rigorous, and it was basically impossible to have any logical or computational problems.

The most important thing is that if the system recognizes your results, then there must be no problem.

Then, he checked the previous eight algebra questions.

When he finished the inspection and found no problems, Teacher Xu finally returned to the study room.

Lin Xiao raised his head and looked at Teacher Xu.

Xu Hongbing smiled at the boy, while thinking about how Lin Xiao did on the question.

I don’t know which question he fell on.

This study room is open all day, but Lin Xiao didn't come all day, which means that he most likely encountered a problem.

Xu Hongbing couldn't help but nodded with satisfaction. His ability to formulate questions had not faded.

At this time, he also saw Lin Xiao getting up from his seat and walking over, but what puzzled him was, why did Lin Xiao come over with a stack of paper?

However, he only thought about this question briefly for a while, and Lin Xiao had already walked to the podium.

Xu Hongbing stopped thinking about it and said with a smile: "How was it? How did you feel about the questions I gave you yesterday?"

Lin Xiao first sighed: "It's too difficult."

Xu Hongbing immediately laughed twice and said: "It is as difficult as it should be. You should have no problem with the first four questions, but the following questions are all difficult at the university mathematics competition level, and they are also questions for the mathematics major group. You After all, I am self-taught, and the self-study time is not long, so it’s okay if I find it difficult and can’t do it.”

"Ah?" Lin Xiao was stunned, and then said: "Teacher, it's really difficult, but the ninth question is more difficult. Among the first eight questions, the first four are really no problem. It took me twenty minutes to write it. It’s over, but the fifth to eighth questions are indeed quite difficult, and it took me nearly seventy minutes to finish them.”

After saying that, he felt relieved and said: "It turns out that the following questions are all college mathematics competition questions. No wonder it is so difficult, especially the last question. It must be the finale question, right?"

Seeing him sighing there, there was only one big question mark in Xu Hongbing's head. What the hell is the ninth question?

Did I ask Question 9?

Maybe Lin Xiao made a mistake?

Also, Lin Xiao said that the first four questions took him 20 minutes, but the last four questions actually took 70 minutes. Is this equivalent to saying that he finished them in an hour and a half?

He was shocked. He took twenty minutes to finish the first four questions and seventy minutes to finish the four competition questions he had asked.

Are you kidding me?

Shouldn't it be focused on a certain question?

He couldn't help but ask again: "Have you finished writing? All the questions?"

Seeing Xu Hongbing's surprised look, Lin Xiao smiled and nodded: "Yes, all questions."

He felt that it was natural for Xu Hongbing to be surprised. After all, it was a competition question. If he, a senior high school student, could solve such a question, it would not be an exaggeration to surprise the teacher, right?

Xu Hongbing looked at Lin Xiao and nodded again. He suddenly felt that he had encountered something extraordinary. He quickly waved his hand and said, "Show me the process of your eight questions."

Eight questions?

After hearing Xu Hongbing's words, Lin Xiao took out the first two papers from the stack of papers in his hand, and then handed them to Xu Hongbing's hand.

These two pieces of paper are the first eight questions.

Xu Hongbing picked up the first piece of paper. The four questions on it were all simple questions. He read them briefly and confirmed that Lin Xiao had indeed done them all correctly.

This was nothing, so he quickly turned over the second piece of paper.

While looking at it, he took out his glasses case from his arms, took out his glasses and put them on, and continued to read carefully.

The questions on the second sheet of paper were more difficult. It took him an hour to figure them out. Two of the questions were modified from the questions he had given before, so he needed to read Lin Xiao carefully. the process of.

So after a while, and after confirming that the last question was correct, he finally put down the piece of paper, and he couldn't stop being shocked at all.

At the same time, he will also think of what he said last night?

Said that if Lin Xiao finished everything, he would eat those scratch papers?

And this table in front of me?

He couldn't help but blush. He threw away the pile of draft paper. As for the table?

Forget it, I don't want to think about it. He is the only one who knows about it anyway. God knows that he knows, but no one knows.

So he consciously changed the topic to avoid feeling embarrassed in his heart.

He praised: "Awesome, really awesome."

"Your talent, I estimate that no student in the past ten years can compare with you."

Although he didn't know what Teacher Xu was thinking, when he heard the teacher praising himself so much, Lin Xiao scratched his head and said modestly: "Actually, it's nothing, I'm still stumped."

"You finished all the questions in an hour and a half. How can you be considered stumped? Don't be humble in just one day. Even I, the professor, feel like I was hit by you."

Lin Xiao touched her nose and said: "Teacher, I didn't finish writing all the questions in an hour and a half. I started doing it after I went back last night. After sleeping at night, I didn't finish writing until about four o'clock this afternoon. Finished."

Xu Hongbing was stunned: "Then you said you finished writing it in ninety minutes?"

Lin Xiao couldn't help but wonder, didn't the teacher hear what he said clearly just now?

He replied: "The first eight questions were written in ninety minutes. The rest of the time was mainly spent on question nine. It probably took... nine hours to complete."

Hearing Lin Xiao talk about the ninth question again, Xu Hongbing became confused.

"Question nine?"

"Yes." Lin Xiao nodded again and showed Xu Hongbing the more than 20 pages of draft paper in his hand: "On this ninth question, I have written so many pages."

Xu Hongbing looked confused, "I didn't ask the ninth question, I asked you the first eight questions."

Lin Xiao was also confused and said: "Didn't you leave three pieces of paper for me? That question was written on the third piece of paper, that's it..."

When Lin Xiao said that, Xu Hongbing suddenly remembered that he did have a piece of paper last night, and Lin Xiao also took it.

Then, he and Lin Xiao said at the same time: "Prove that the Fibonacci sequence has infinite prime numbers (ah)?"
