Top Student: Wasteland Technology Invasion

Zheng Quanxun snorted coldly, "There's something fishy going on here! Who knows what your mentor might have done for you behind the scenes."

He originally did not want to be Lin Chuan's enemy.

But when Zheng Quanxun saw that Lin Chuan had inexplicably transferred from the Applied Mathematics Class 2 to the Qiushi Class and had actually received a scholarship of 10,000 yuan in just a few days, he could no longer remain calm.

Zheng Quanxun's family was of modest means, and he really wanted to win a school scholarship.

Why was Lin Chuan able to get into the Qiushi Class and receive a scholarship through connections?

Why is it that Zheng Quanxun, despite studying so hard, is always a little worse than Lin Chuan in everything?

This is not fair!

Today he must reveal everything.

Lin Chuan really wasn't in the mood to listen to Zheng Quanxun's continued rambling.

He knew that he and Jung Jeon-hoon hadn't gotten along well in high school, and he didn't want to explain anything now.

In a few days, when everyone finds out that he has published a paper, or that he has achieved good results in the midterm exam, everyone will naturally understand his abilities.

There's no need to waste time explaining now.

But now, Jung Quanxun is subtly pointing the finger at Director Lu.

Professor Lu helped him pay the publication fees for his paper, found someone to expedite the review process, and helped him apply for scholarships and various subsidies. He was very kind to Professor Lu.

Even knowing that Zheng Quanxun's dirty water wouldn't affect Director Lu in any way, Lin Chuan still couldn't just sit idly by.

He had to do something to repay this kindness.

just now.

Faced with public skepticism, the solution was simple.

That is to crush them using mathematical methods.

In mathematics, you either succeed or you fail.

There's really no twist or turn involved.

Lin Chuan risked his life to study math for so many days in the wasteland, how could he possibly fail!

Thinking of this, he replied, "You seem unqualified to give me a question."

Wow!

As soon as Lin Chuan said this, the previously noisy corridor outside the classroom instantly fell silent.

Many people know about the feud between Lin Chuan and Zheng Quanxun, and were originally looking forward to some gossip, but Lin Chuan directly said that he was not qualified.

Regardless of whether Lin Chuan has real skills or not, it seems Zheng Quanxun can't expose him.

Is this how this farce is going to end?

Just then, a voice rang out from outside the crowd, "What's going on? Why all the noise?"

Upon seeing the visitor, many students from the Department of Applied Mathematics greeted him in hushed tones, "Professor Zheng."

Zheng Rui is in his thirties and is a lecturer for the first-year elective course "Introduction to Mathematics" in the School of Mathematics.

"Teacher Zheng," Zheng Quanxun called out warmly.

No one else would know that Teacher Zheng and he were related, sharing the same clan and surname. Although they were beyond the fifth degree of kinship, Zheng Quanxun could still call Teacher Zheng "uncle".

In fact, Teacher Zheng's passing by here today was something he had prepared in advance.

Thinking of this, Zheng Quanxun deliberately explained, "It's like this, Teacher Zheng. Lin Chuan just won the school's top scholarship, and it's still in the public announcement stage. However, his math performance in high school was very average, so everyone has doubts and wants to verify his true ability."

Teacher Zheng frowned and looked at Lin Chuan. "Lin Chuan, the scholarship is an affirmation of your learning ability, but it also means that you will be subject to supervision. If you have the ability to answer the reasonable questions raised by your classmates, you should clarify them on the spot. Wouldn't that be better? Being secretive will only make people suspect that there is some kind of unfairness in education."

After a pause, Teacher Zheng spoke in a lecturing tone, "How about this, I happen to have a problem, a thought-provoking question I gave to the freshman interest group a few days ago. Could you solve it for everyone?"

Zheng Rui knew that Lin Chuan was Professor Lu's student, and that Professor Lu had very strong connections in the School of Mathematics at Yueyang University.

But so what?

Teacher Zheng worked her way up to become a lecturer at Yueyang University, but it was difficult to take the next step and even become a level 7 associate professor.

Why should someone like Lin Chuan, who has connections, receive such treatment right from the start?

Today he's going to give Lin Chuan a challenge to test his true abilities.

At the same time, Teacher Zheng left himself a way out.

His words were very clever.

To outsiders, he was upholding the dignity of the academy; whether Lin Chuan solved the problem he set or not, it wouldn't cause him any loss.

As for what Lin Chuan just said to Zheng Quanxun, it was naturally invalid.

As a young lecturer at Yueyang University, Professor Zheng certainly has the qualifications and ability to set questions for Lin Chuan.

At this moment, a student from the Applied Mathematics Class 5 in the crowd nudged his friend's arm and said, "I didn't expect to see such a big show before the National Day holiday."

"Doesn't this look like something out of a martial arts novel, where some unconventional martial artists are too flamboyant and eventually attract the attention of a prestigious sect to suppress them?"

"You know what, I really feel that way. I don't know if Lin Chuan has any real talent, but with this commotion, even if he can't answer Professor Zheng's question, he's already made a name for himself. From now on, who in the School of Mathematics will dare say they don't know who Lin Chuan is?"

"Make a name for yourself? Heh, if Lin Chuan doesn't have real skills, he won't be able to keep the scholarship issue under wraps. If some shady dealings are exposed, it's uncertain whether Lin Chuan will be able to continue studying at our school."

"Holy crap, it's true."

……

Sun Ang, standing next to Lin Chuan, became anxious. "Teacher Zheng, this isn't fair..."

"Sun Ang!" Lin Chuan called out to his roommate, glancing at Teacher Zheng and then at the students gathered around. "Teacher Zheng, where's the question?"

Having come this far, he could no longer back down.

He doesn't need to prove his abilities to anyone.

But now that the other party has come as a group to question him, he will not let go of this opportunity to slap them in the face.

For many days he had been shuttling between the two worlds, using every means to learn mathematics, so how could he be afraid of the other party?

Lin Chuan's confident demeanor stirred something within Teacher Zheng for no apparent reason.

Could it be that Lin Chuan really has some trump card up his sleeve?

Otherwise, how could he be so calm?

But with the die already cast, Teacher Zheng had no time to think. He stepped into the classroom directly opposite the corridor, picked up the chalk, and began writing furiously on the blackboard.

Let A be an m×n real matrix and B be an n×m real matrix.

"Prove: det(Im−AB)=det(In−BA), where Im and In represent m-order and n-order identity matrices, respectively. If Im−AB is invertible, prove that In−BA is also invertible. Find the expression for (In−BA)^−1."

After the question was finished, the students from each class who were watching had different expressions.

Some people think this question is too simple because the question stem is so short; anyone could do it.

Some students also vaguely discovered the hidden tricks in the questions, and it was not easy to solve them.

Only Zheng Quanxun was smug.

His uncle had explained the problem to him, and he had seen the answer, but even if he were to answer it now, it would be difficult for him to do so without referring to the answer.

Lin Chuan has absolutely no chance of getting the answer.

"Alright, Lin Chuan, you can come over and answer now."

Teacher Zheng put down the chalk and extended an invitation to Lin Chuan, who was still standing outside the classroom.

Since he's going to do it this time, he's going to do it to the best of his ability.

There is absolutely no way Lin Chuan will get the answer.

Even though Lin Chuan was a student in the Qiushi Class, and even though he got a perfect score on the Qiushi Class entrance test, Teacher Zheng was still confident in his questions.
