**I will reward you well this evening!**

There are a total of 53 students, and almost 70% of them skipped class. Isn’t that like slapping professor Dai’s face?!

The students who skipped class could only accept that they were unlucky.

Dai Pingbo is already benevolent enough not to report it to the school.

In fact, Lin Xian could guess what these students who skipped classes had in their minds.

They must have all inquired about Dai Pingbo.

Finding out that he has an easy-going personality, and he seldom calls names for attendance, they thought it should be fine to skip a few classes occasionally.

However, there are a lot of students who think this way. In fact, everyone does.

To be honest, if it wasn’t for his sudden interest in mathematics, he probably would have also skipped class today.

After calling the names, Dai Pingbo glanced at Lin Xian who was seated in the front row, and then his expression softened a little.

“Let’s begin the class now!”

Dai Pingbo picked up a chalk and began to teach.

“Mathematical modeling is the most common application of mathematics, this is the mathematical representation of a real-world scenario. If you take a human as a whole, then mathematical modeling is equivalent to the human skeleton…”

Dai Pingbo’s teaching level is very high. In just a few minutes, he introduced the specific content and function of mathematical modeling.

Put simply, mathematical modeling is turning mathematical knowledge into practical applications in real life.

This requires not only mathematical skills but also a strong logical thinking ability, as well as vast reserve knowledge.

One application of mathematical modeling for example is in creating a folding chair. It involves a series of knowledge in materials science, human mechanics, engineering, and others.

In addition, you must have a certain knowledge of computer technology, because mathematical modeling will often carry out tedious and complex calculations, and the use of computers can improve efficiency

Because of the atmosphere before, the dozen or so girls in the back row are behaving well, listening carefully, and some even taking notes.

But as they listen, they realize that the situation seems not right.

*‘Who am I?’*

*‘Where am I?’*

*‘What am I doing?’*

After this triple soul torture, the girls finally gave up and began to play with their mobile phones.

Dai Pingbo just ignored them and continued teaching.

On the other hand, it was Lin Xian who experience as if having his own tutor.

It could be clearly seen that Dai Pingbo was focusing on him as he taught.

When he talked about certain topics, he would stop deliberately to ask if Lin Xian understood.

If Lin Xian shook his head, he would repeat what he said several times.

A university professor as a tutor? This treatment is too awesome!

After the 90-minute class, Dai Pingbo took a sip of tea and asked with a smile, “How was it?”

Lin Xian nodded and said, “It feels like opening the door to a new world. It is very interesting.”

“Mathematical modeling is like basic mathematics. The best way to improve your knowledge and skills is to solve a lot of problems. Don’t be afraid to be wrong. You can only learn and improve from your mistakes.”

Dai Pingbo smiled and said kindly: “I will give you an assignment, go back and do it slowly. Just hand it over to me in the next mathematical modeling class.”

After saying that Dai Pingbo took out a pen and a blank piece of paper and quickly wrote down a problem.

After receiving the paper, Lin Xian was a little stunned.

The problem read as

【Hole depth calculation: If you are standing at the opening of a hole with only a calculator and a stopwatch out of curiosity, you wanted to calculate the depth of the hole by throwing a stone and listening to the echo as it drops to the bottom. Given that the stone had a mass m of 1kg and the echo appears after 5 seconds, calculate the depth of the hole under the following conditions:

(1) Air resistance is not considered

(2) Air resistance is a factor, coefficient = 0.05

(3) Air resistance is a factor, coefficient = 0.0025

(4) The above three cases consider the time it takes for the echo to return. 】

Seeing Lin ‘Xian’s expression, Dai Pingbo patted him on the shoulder and said with a smile: “Go back and solve it slowly, even if you can’t do it, it doesn’t matter.”

Lin Xian nodded and said, “Okay, I will give it a try.”

After Dai Pingbo left, Lin Xian suddenly found that the girls in the classroom did not leave yet. And all of them were looking at Lin Xian curiously.

They had the same thoughts as Lei Hongguang. A rich and handsome guy like Lin Xian should typically be just flirting with girls, enjoying racing, and visiting nightclubs.

No matter how, he can also play golf and bowling.

Lin Xian’s behavior and personality seemed too far from what they imagined, so they couldn’t help but feel a strong sense of contrast.

Lin Xian just ignored them, packed his books, and returned to the dormitory.

Now that the non-residential procedures have been completed, he can be out of the university at any time.

Lin Xian stuffed his Alienware notebook and the homework given by Dai Pingbo into his shoulder bag and then leisurely drove his Ferrari out of the campus.

..…

As he arrived home, pushing the door open, Lin Xian couldn’t help but be slightly taken aback.

The whole house was transformed.

There were some art paintings hanging on the walls and ornaments placed on the coffee table. Additionally, on the originally empty balcony were hanging basket chairs.

Zhuang Tong and Nie Qinqing were lying comfortably on the hanging basket chairs, holding a laptop, and seemed to be watching some online drama.

Seeing Lin Xian has come back, Zhuang Tong sat up and smiled and said, “Dear, you are back?”

“Yes. The home is well arranged.” Lin Xian said with satisfaction.

Zhuang Tong’s vision and aesthetics are very good. The decorations fit the style of the house very well.

What satisfies him the most were the hanging basket chair on the balcony. Just thinking of lying on it while reading a book on a winter afternoon is already so comforting.

“Do you like it?”

Zhuang Tong’s expression of waiting for a compliment is extraordinarily cute.

“I like it very much. I will reward you well this evening!”

“Cough! Can you be a little discreet? There is someone else here!” Nie Qingqing said in a low voice.

This shameless couple is becoming more unscrupulous, they even started to flirt in front of her.

Lin Xian put on his slippers and joked, “You can join too. I wouldn’t mind.”

Nie Qingqing’s appearance is not low, with at least a face value of 91 and a figure of 87. Although a little inferior to Zhuang Tong, she is still a proper goddess.

There should also be a lot of licking dogs lurking around her.

The two have their own strengths. If she wants to, Lin Xian doesn’t mind having another lover.

“Hehe. I don’t mind either. It might be for the better. We can be good girlfriends for a lifetime.” Zhuang Tong said with a smile.

For a split second, Nie Qingqing was moved.

But the thought that her parents might kill her if they found out that she is a mistress prompted her to drop the crazy idea.
