I failed a course, and the system became my study supervisor.

Chapter 5 A Small Step Towards Scientific Research
Xu Ling's home is not far from the subway station. It is an old residential area. Xu Ling's grandfather bought a house there with foresight, and the family moved from the countryside to the city. They have lived there for almost forty years.

Arriving at the door of his house, Xu Ling's mood was beyond words. His excitement at this moment was even greater than when he received the mission reward.

"dong dong dong"

Xu Ling knocked on the door.

"Here I come——" Xue Yan's loud voice came from the door.

"Crack!"

The door opened and Xue Yan saw Xu Ling standing in front of the door.

"Hey? You still remember to come back! Young Master--" Xue Yan said in a sarcastic tone.

Xu Ling was helpless in the face of her somewhat neurotic mother: "I don't deserve it! I was wrong. Now I'm back, right?"

"Come in now that you're back. I thought you were dead outside!" Xue Yan continued unhappily.

Xu Ling nodded awkwardly, tiptoed, avoided Xue Yan's body, and went into the room.

After all, a mother worries about her son even when he is far away. Seeing Xu Ling return safely, although Xue Yan said some unpleasant things, her mood improved a lot. In a blink of an eye, she went into the house humming a song to cook.

Without the pressure of his mother's words, and with the peaceful and warm atmosphere at home, Xu Ling finally relaxed and collapsed into a heap on the sofa.

After a long rest, Xu Ling remembered the book "Frontier Applications of Fourier Analysis" he had just obtained.

Turning on the computer, Xu Ling began to read with great interest:

The material roughly talks about four aspects, namely the application of Fourier analysis in deep learning and data analysis, physics, engineering technology and finance.

These applications are quite cutting-edge, and Xu Ling is still confused by them. He can only somewhat understand the solutions to various mathematical and physical equations in the field of physics, and it is difficult to comment on the others.

I can recognize each word individually, but I can't understand them when they are put together.

Specifically, the material elaborates on the important role of Fourier analysis in the simple solution of various complex equations in physics, the derivation of relevant theories, the construction of special functions and transformations, and numerical approximate solutions.

In addition, the document also focuses on introducing some unresolved conjectures in the field of solution, such as the high-frequency attenuation conjecture, the critical space conjecture, the small initial value global solution conjecture, etc.

Looking at the unsolved conjectures highlighted in the information, Xu Ling felt extremely excited.

What if I could prove one day?

But Xu Ling just thought about it. How could a poor student like him who failed three subjects have such a good reputation? Unless he cheated.

Huh? Cheating?
Xu Ling suddenly remembered that he had a system!

Isn't this definitely cheating?

The system also gave a prompt at this time: "New tasks have been released, please check in time!"

What is this called?
This is called the system moving at your will!

Xu Ling was overjoyed and quickly opened the taskbar.

【Ordinary tasks

(1) Library check-in task (suspended)
……

Glory Mission:

(1) Prove yourself
……

(2) A small step towards scientific research (the first stage): Please make full use of the time at home during the winter vacation to study the supplementary material "Frontier Applications of Fourier Analysis". The system will assess the host within the first day after the host returns to school.

Completion Reward: Successful assessment will reward 10 motivation points and unlock the next round of tasks.

Failure penalty: If the assessment fails, 10 motivation points will be deducted and you will not be able to proceed to the next task.

Rejectable: Yes]

It turned out to be a glory mission, and it was a series!

Xu Ling was pleasantly surprised and chose to accept the task without hesitation.

What's more, the name of this mission, Xu Ling believes it will definitely bring him a huge surprise.

Just when Xu Ling was still immersed in great joy, the sound of a key being inserted into the lock came from outside the door.

Needless to say, it was Xu Ling's father, Xu Guoqiang, who had returned. Xu Guoqiang was a veteran employee of a state-owned enterprise, with a simple and honest personality, a slender figure, and a fair complexion.

"click"

When Xu Guoqiang opened the door and saw Xu Ling who had returned, his eyes lit up noticeably and all the fatigue on his body disappeared.

"When did you come back?"

"afternoon."

"How long have you been back?"

"Well... it's been a while."

Are all fathers in the world like this?

Xu Ling looked at his father, feeling speechless.

Xu Guoqiang seemed to realize that he had asked two identical questions. He looked a little embarrassed and his face flushed slightly.

The awkward atmosphere was not broken until Xue Yan invited them to eat. The father and son sat down at the dining table feeling relieved.

"Lingzi, the last time I called you I heard you said you failed the exam. What happened? Is there any problem?" Xue Yan spoke first.

Xu Guoqiang also turned his gaze to Xu Ling, looking somewhat worried.

"It's okay! Mom and Dad, don't worry, I can still take the make-up exam. I'm confident I can pass it!" Xu Ling patted his chest and answered confidently.

"As long as you're okay, by the way, your cousin, the one from your second uncle's family, will be coming to our house tomorrow. I want you to help him with his homework."

Xue Yan continued.

"Isn't he just in elementary school? What's there to tutor him for? Don't show off every day just because you have a college student at home." Xu Ling teased.

"Oh? Do I need you to show off? Why are you so fussy all day long? You just flatter yourself." Xue Yan said unhappily.

Without giving Xu Ling a chance to speak, Xue Yan continued, "Just teach me when I ask you to. Why are you talking so much nonsense?"

After saying that, he glared at Xu Ling.

Seeing his wife's unhappy expression, Xu Guoqiang immediately tried to smooth things over:

"Eat, eat, eat first."

The family of three was silent for a while, eating the food in their bowls in silence.

However, this was just a small episode. After dinner, the atmosphere in the house returned to warmth and harmony.

This is also the basic ecology of Xu Ling's family.

A tough northern woman, a classic Shanghai man, and a ragtag son. If there weren't such an episode, it would be abnormal.

After helping his mother clean up the dishes, Xu Ling immediately plunged into studying the information.

Now, Xu Ling is not only interested in the information in his hand, but also regards it as a small gold mine that has not yet been mined.

But in the eyes of Xu Guoqiang and Xue Yan, Xu Ling's condition was incredible.

"Guoqiang? Is this kid being pushed too hard by us? We've never seen anything like this before."

"You didn't force him? Weren't you the only one who mentioned the previous incident of failing the exam?"

"Has this child changed his personality? Has he been stimulated?"

"It's possible. Why don't you ask him?"

"Never mind, it's not a bad thing."

After saying that, the couple looked at each other and nodded.

Xu Ling did not hear his parents' grumblings, his mind was completely focused on his studies.

If Xu Ling heard it, he would be in tears and laughter.

Is the image of myself as lazy, careless and undisciplined so deeply ingrained?
