Chapter 4

After submitting the assignment, he headed straight for the Comprehensive Office Building.

Wang Hao went to the office on the sixth floor, waving to the people he knew.

He brewed a cup of coffee and sat down.

He opened the lesson plan he had prepared and went through it carefully again.

It was still nerve-wracking to give his first class.

In his previous life, he had worked for a decade at a tutoring institution, never imagining that one day he would be teaching at a university, giving professional math lectures to math students.

Thinking about it, he was still very excited.

The lesson plan was prepared the day before, covering the content of the class, with the core knowledge point being one—

Fourier Transform.

The Fourier Transform, also known as the Fourier Transformation, based on his deep understanding of the content, he divided the Fourier Transform into several parts, planning to give a simple explanation of the surface level.

The undergraduate content was still quite simple, just an introduction to the basics of the Fourier Transform.

9:30 AM.

Wang Hao went to the large classroom on the side of Building No. 3.

He pushed the door open.

He scanned the classroom and found that only a dozen or so students were scattered, mostly sitting in the middle and back rows.

Only one boy was sitting in the front row.

The boy had his textbook on the side and was focused on playing with his phone, even laughing out loud.

Wang Hao walked straight over.

"Hello, classmate, what's your name?" Wang Hao glanced over and saw that he was watching short videos, so he asked.

The boy looked up in confusion, sized up Wang Hao, and said, "Bishenggong?"

"Must succeed?!"

Wang Hao raised his thumb high, "What a great name! I wish you success in the future, just like your name."

Bishenggong blushed slightly, embarrassed and loudly asked, "Who are you? What's up?"

Wang Hao didn't answer but picked up the student list and scanned it from top to bottom.

Class 2, Bishenggong!

Match!

Bishenggong leaned over to take a look, then with great surprise, he examined the person in front of him, saying in disbelief, "You are... Wang Hao? Teacher Wang?"

"It seems you know." Wang Hao smiled.

"You're so young, I thought you were a student!" Bishenggong quickly explained his earlier behavior.

"Many people say that."

Wang Hao touched his cheek, smiled indifferently, and asked, "It's my first time teaching you. Can you tell me the specific progress of your class?"

He knew the general progress and had prepared the lesson plan, but different classes might have slight differences in progress.

Bishenggong immediately flipped through his book.

Others also heard their conversation and couldn't help but look forward.

A few of them came closer, calling out "Teacher Wang," "Teacher Wang"; many others watched from a distance, whispering about Wang Hao.

Wang Hao's story had made the news, and they had heard that he would be their course teacher.

Although the news was negative, Wang Hao was still a doctoral graduate from Donggang University in his early twenties, with a bit of a "legendary" aura.

The students were whispering, "This teacher is really young. I saw in the news that he's 23, a doctoral graduate from Donggang. He's a genius!"

"But he's also quite unlucky, with experimental data errors and losing his job."

"Our class is really something, having two teachers in a row. One old professor retired early, and now this one, we can't find anyone younger."

"If you look closely, he's actually quite handsome!"

"If he had a student-teacher relationship, my goodness, he'd be a senior, feeling younger than me!"

"Because you look old..."

Although Wang Hao had a research scandal, it was mainly within the academic circle.

From the perspective of ordinary students, Wang Hao could be described as a "legend." A 23-year-old doctoral graduate from Donggang was something they could hardly imagine.

So what if he had a research scandal? He was still a young doctor and could still be a lecturer at a university.

Even if he couldn't stay at the university in the future, finding a job elsewhere would be easy.

They were just undergraduate students at Xihai University.

Xihai University was just an ordinary university, at most a "key" university, not even in the top three in the northwest region. It was not easy for undergraduate graduates to find a good job.

Let alone causing losses due to experimental errors, they didn't even have the qualifications to participate.

...

Class time was approaching.

Wang Hao sat behind the podium, carefully reading the content in the textbook.

This class was about "Fourier Transform," a widely used mathematical method, primarily applied to solving partial differential equations.

"Fourier Transform" also had many applications in other fields.

For example, computer algorithms.

"Discrete Fourier Transform" was one of the main algorithms in computers.

Wang Hao suddenly had an idea, "If I explain the Fourier Transform, I will definitely get many related inspirations."

"Then, setting up a research task related to the Fourier Transform would definitely be more efficient!"

"Right!"

He immediately opened the system and tried to create a task named "Fourier Transform."

[Task creation failed, "Fourier Transform" is not a research content.]

"Failed?"

Wang Hao frowned, thought carefully, and added a few words.

[Task creation successful, new task opened!]

[Task 2]

[Research Project Name: Algorithmic Application Expansion of Discrete Fourier Transform (Difficulty: C)]

[Inspiration Value: 0]

Indeed, it was feasible!

Wang Hao's eyes lit up. He looked at the time and then at the students in the classroom, feeling much more affectionate.

Many students entered the classroom just in time.

Coming and going, the flow was constant.

Wang Hao stood at the podium, his young face, ordinary attire, and gentle smile made the students feel close, as if the one teaching them was a peer student, not a university teacher.

Many students couldn't help but think, "This Teacher Wang seems very approachable!"

"Even if I skip a few classes, I can probably talk to him and it will be fine!"

"The exam will definitely be easy to pass!"

"I've got this subject!"

Wang Hao stood with a smile, seemingly indifferent to everything, until no more students entered and the last student found a seat.

He tested the microphone volume and said, "Everyone, please be quiet, class is starting."

"Today is my first formal class at Xihai University. To be honest, I'm quite nervous. I spent several hours preparing the lesson plan."

"My name is Wang Hao, very ordinary. I believe many of you already know. If you don't, you can look at the news from a few days ago about the material research at Donggang University. The male protagonist who made a major mistake causing significant losses is me."

"Ha ha ha~~"

Many students laughed.

They found it amusing that the new teacher would start the class by self-deprecatingly mentioning his "work mistake in the news."

When the classroom quieted down, Wang Hao continued, "This incident was very hard for me. Regardless of right or wrong, I was so upset a few days ago that I almost jumped off a building..."

He said it jokingly, but no student believed him.

Everyone thought he was joking.

"But life must go on, and what needs to be faced must be faced, just like me standing here to teach. I can't choose my students, and you can't choose your teacher."

"I just hope that all of you will listen carefully and correctly grasp the knowledge points and methods of the course 'Partial Differential Equations.'"

"You are in the Applied Mathematics major, and 'Partial Differential Equations' is one of the most important professional courses."

"Whether you do research in the future or any other work related to mathematics, you will definitely use it."

Wang Hao paused here, becoming more serious, "I have low requirements for teaching."

"I have only three requirements for you."

The students listened attentively, thinking that with such an approachable teacher, the course would be easy to pass.

But as they continued listening, they felt something was off.

"First, you must attend class and not be late. Starting from the next class, any student who is late without reason four times or skips two classes will be directly marked as failing, even if they score full marks on the exam."

"Second, you must listen carefully in class. No sleeping or using phones. If I catch you once, I will deduct points from your regular score, and if it happens multiple times, you will fail."

"Finally, all homework must be completed independently. If you plagiarize, please don't let me find out. During the problem-solving sessions, I will randomly check individual students based on their homework, and I may also ask some students to explain to the class."

"That's all three small requirements."

Wang Hao said the requirements seriously, and the classroom fell silent. The students looked at his smile, feeling it was like the smile of a demon.

It was truly terrifying!

How could he be so strict? Wasn't he afraid of too many students failing?

Wang Hao seemed to hear their thoughts and immediately explained, "Some of you might think, with such high requirements, many will fail."

"Indeed, other teachers might worry about this." He smiled, "I don't worry."

"You might not know, but my contract with the school is only for one year. Whether I can continue as a lecturer next semester is uncertain, but it's unlikely."

"So, do you think I care how many students fail?"

Wang Hao pursed his lips and continued, "Even if all of you fail, and none can pass, it's fine. I don't care..."

He still smiled.

The students in the classroom were stunned, their minds filled with frustration.

Is this a university teacher?

Is he a demon?
