**Heart of a Champion**

Taking Lin Xian’s shoulder bag, Zhuang Tong acted like a caring little wife and asked thoughtfully, “What fruit would you like to eat? I’ll cut it for you.”

“No. It’s fine. I will have to solve a math problem for a while. You may go and do something first.”

Lin Xian was very satisfied with Zhuang Tong’s attitude and so he squeezed her pretty face lightly.

“Hmmn!”

Zhuang Tong exhaled softly and pecked Lin Xian on the cheek and then went back to continue watching the online drama with Nie Qingqing.

The two have very similar personalities.

If there is no one to accompany her, Zhuang Tong can watch online dramas for a day or do something else at home by herself. There is no need to worry about her being bored.

This is also one of the reasons why Lin Xian would agree to have her as his mistress.

Many mistresses would feel empty inside and lonely after they don’t have to worry about money and lose their motivation.

Additionally, because they are just a mistress, their partner cannot be with them all the time so many mistresses will go out to look for excitement and cheat behind their partner’s back.

But Zhuang Tong is different. With her character, she is destined to never feel empty and lonely.

Just like Lin Xian, she feels that there are so many interesting things in the world, and she believes that life is too short.

Lin Xian took out his pen and paper and calmed himself and began to think about how to solve the problem given by Dai Pingbo.

At first glance, the problem seemed overwhelming.

This is typical of mathematical modeling questions.

It requires a strong logical ability to be able to put a hypothesis, and then use mathematical formulas to fill in the hypothesis little by little. After analysis and verification, finally, a set of correct mathematical models is obtained.

And the most interesting part of mathematical modeling is that there is no standard answer.

For example, using mathematical modeling to make a folding chair, the shape of the folding chair will vary among different people.

And although the shapes may be different, as long as it works, one cannot say that the mathematical model used is wrong.

There is no standard answer, however, there can be good or bad answers.

Someone who is able to design a folding chair that is more comfortable and portable means better modeling was used.

The question of Dai Pingbo is also the same.

Looking at the questions on the paper, Lin Xian’s brain ran fast, and all the mathematics he had learned before kept flashing in his mind.

After pondering for a while, Lin Xian suddenly had an idea.

What this problem requires is actually the concept of the speed of falling objects and displacement over time.

This belongs to Newtonian mechanics, so you can try to establish a model using partial differential equations.

Once the model is established, a series of calculations and verifications follows.

Thinking of this, Lin Xian’s mouth couldn’t help but evoke a smile, and he quickly wrote lines of numbers on the paper using the pen in his hand.

“Let T be time, G the acceleration due to gravity…H the depth of the hole.

“Solution 1: Galileo’s law of free fall states that…”

…..

…..

Before he knew it, an hour has passed.

Zhuang Tong glanced at the time, stretched her waist, and said, “It’s getting late, it’s almost time for dinner!”

“There seem to be no more ingredients in the refrigerator.” Nie Qingqing said.

“It’s okay. I’ll just go to the supermarket to do some shopping.”

Zhuang Tong jumped off the hanging basket chair and went to Lin Xian and asked, “Dear, what do you want for dinner?”

However, Lin Xian did not answer and just kept his head down while writing.

“What are you doing that you’re so focused on?”

Nie Qingqing murmured and stepped forward to take a look.

Her eyes were dazzled looking at the numbers and symbols, and lines of equations made her feel so dizzy.

Who can stand this?

Excuse me! Goodbye!

Zhuang Tong couldn’t help but say: “I don’t understand at all. I’d better cook!”

At this time, Lin Xian raised his head and smiled: “I am okay with whatever you want.”

“Then, let’s go shopping!” Zhuang Tong smiled.

“You may go ahead!”

After saying that, Lin Xian lowered his head again.

Once he finds inspiration, the next steps seem to be just a matter of course. This feeling is so refreshing that he can’t help but indulge in it.

…..

Seated on the Beetle, Nie Qingqing fastened her seatbelt and said, “Lin Xian feels so weird!”

“Why?” Zhuang Tong asked with a smile.

“I just feel that he is completely different from the other rich second generation. I really can’t imagine him seated there for more than one hour solving math problems.”

Zhuang Tong held the steering wheel and looked at her meaningfully.

Nie Qingqing couldn’t help but ask, “What’s wrong?”

“Hehe. I am thinking that we might really be best friends for a lifetime!” Zhuang Tong smiled meaningfully.

Nie Qingqing pretended to stay calm and said, “We…We were supposed to be best friends for a lifetime!”

“Haha!”

Zhuang Tong just laughed and did not expose her.

As a woman, how could she not know that when a woman started to become interested in a man, it means she is not far from falling in love with him?

And a man like Lin Xian is like a black hole. Attracting women is a normal thing.

The two went to the supermarket to do some shopping.

After returning home, Lin Xian was still doing the math questions with his head down.

Seeing this, they quietly walked into the kitchen carrying some ingredients, so as not to disturb him.

At seven o’clock in the evening…

Lin Xian finally raised his head and put down the pen in his hand and let out a long breath of relief.

“At last, it’s done!”

Looking at the dense mathematical models and solutions in the three to four pages white papers, Lin Xian felt an unparalleled sense of achievement deep inside

According to the conditions of the problem, he established a total of four models and proved the logic self-consistent through verification and analysis.

As a final step, he only needs to import these mathematical models into the computer and use C++ or MATLAB to obtain the results of the equations.

To be honest, this problem is his current limit.

In Mathematical modeling, knowledge of basic mathematics is the key to opening the treasure house. The more keys you have, the greater chance of opening the door to the treasure house.

“I still need to keep learning!” Lin Xian heaved a sigh.

Suddenly, a system prompt sounded in Lin Xian’s mind.

[ Ding! Congratulations to the host for solving the problem and triggering the hidden mission: ‘Heart of a Champion’! ]

[ Heart of Champion ]

[ Task Requirements: Participate in Higher Education Club Cup – National College Students Mathematical Contest in Modeling]

[ Mission Progress: 0% ]

[ Mission Rewards: The final reward depends on the host’s performance in the competition. ]

…..

Damn it!

Solving problems can also trigger a task?

But isn’t this task a bit too difficult?

Higher Education Club Cup!

In the National College Student Competition, there are a lot of participating students from 211 colleges and universities. There are also other schools known in mathematics such as QHBD, FD, and TJ. It is really difficult to go up and top the ranks.
