"What kind of question is this? Yunyun has been like this for a long time. Is the question really that difficult?" Wu Guixiang couldn't help it, her face full of worry.
"It's a very difficult problem." Qin Ying thought for a moment and said, "No one has solved it for over a hundred years."
"What?" Zhang Xinlan was dumbfounded. "What's the point of Yunyun trying to solve a problem that hasn't been solved for over a hundred years? Isn't this just asking for trouble?"
She really couldn't understand why all this effort was needed.
Qin Ying smiled and didn't feel offended by Zhang Xinlan's words, because she knew she didn't understand these things. "It's because no one has solved it, so I try to calculate it."
Li Xiulian smiled and said, "This is a puzzle that no one has solved for over a hundred years. If we can solve it, wouldn't that be amazing? We'll be more amazing than anyone else in the past hundred years."
"No matter how strong you are, you can't be like this." Compared to her child's health, Wu Guixiang didn't care about those things. She looked disapproving, "No matter what you do, you have to take care of your body first. I think if Yunyun continues like this, her body will not be able to bear it sooner or later."
"Don't worry, Mom. I'm taking good care of her." Qin Ying was certainly concerned about her daughter's health. "I'm watching her. I'll bring her food in later."
"OK."
Su Qingyun was completely unaware of her family's worries. She was immersed in the world of mathematics. The Riemann hypothesis occupied her entire brain. Countless mathematical formulas and theorems flashed through her mind, forming logical chains, which she then overturned one by one. In this way, she kept experimenting to verify the possibility of the Riemann hypothesis.
The calculation manuscripts in her hands already amounted to three thick volumes. She continued to calculate very quickly, and one after another, slightly sloppy numbers and letters were born under her pen.
She was like this at home and at school. After class, Su Qingyun's pen was still moving very quickly, and she didn't notice that the bell had rung.
"Qingyun, why don't you take a break?" Ji Yue couldn't help it. She had been in this state all morning, and he was really a little worried.
"It's okay, no need." Su Qingyun took the time and replied to him quickly without raising his head.
She was afraid that if she stopped, her train of thought would be interrupted.
Ji Yue pursed his lips, helpless, and had to get up to help her get some water and put it on the corner of her table.
"Thank you." Su Qingyun still didn't raise his head.
Seeing her like this, Ji Yue felt a sense of crisis in his heart again. He had to work hard. Thinking of this, he took out the book and continued reading.
Until noon when school was over, the two were still studying hard. Xia Qiu came to call them to eat and stood in front of them, but they ignored her.
"You two don't have to fight so hard, do you?" Xia Qiu looked incredulous. "Do you still want to keep people alive?"
These two people have always been the first and second place and have never wavered. After winning various awards, they are still working so hard to learn this and that. How can ordinary people like them survive?
"Let's go, let's go eat." Xia Qiu waved his hand in front of the two of them, "Today the cafeteria has fried meat with black fungus, but if you go too late it will be gone."
After Su Qingyun finished writing the last letter, he finally raised his head, and Xia Qiu was startled.
"Qingyun, your eyes are too red, aren't they?"
Su Qingyun's eyes were red, with some thin bloodshot veins, and he looked extremely tired.
"Please take a break and stop writing."
Ji Yue put down the book and frowned when he saw Su Qingyun like this. He took the pen from Su Qingyun's hand and said, "Let's go and have dinner."
Su Qingyun pressed his tired brows and finally stood up. "Let's go."
Her voice was a little hoarse when she spoke.
When they arrived at the cafeteria, Ji Yue asked her to sit down and rest. He went to get her some food and also went to the school cafeteria to buy a bottle of soda.
"Drink some water first." Ji Yue handed her the soda.
Su Qingyun took a small sip and felt his dry throat felt a little better.
"Qingyun, eat more." Xia Qiu generously gave the meat from his plate to Su Qingyun. "Look at how much weight you've lost recently. What's going to happen if you continue like this?"
"It's not that exaggerated." Su Qingyun was a little helpless, but she also knew that her recent state had scared them, so she picked up the chopsticks and started eating slowly.
"By the way, Qingyun, what about the Li conjecture you calculated? Are you going to figure it out?" Xia Qiu asked curiously.
"No." Su Qingyun shook his head. "It's just that I've found a way to think about it. I haven't found any problems yet, but I've reached a bottleneck. It will be very difficult to move on to the next stage."
Although it is very difficult, Su Qingyun is already very satisfied with what she has calculated so far. After all, that is the Riemann hypothesis, not just any math problem. If she can prove it easily, she will realize its authenticity. At present, this stage victory is already very good.
"So what are you going to do next?" Xia Qiu asked again.
Ji Yue said: "Take a break for a while, you are too tired, and let your brain relax. Maybe you will have other unexpected gains and ideas."
"Yes." Su Qingyun nodded. "I plan to organize all the information I have so far and write a paper to send out."
"Paper?" Xia Qiu's eyes widened. "Qingyun, you're going to publish a paper?"
For her, the word "thesis" only existed in her hearing.
"Well, let's try sending it." Su Qingyun smiled.
"How are your studies going recently?" Su Qingyun asked Xia Qiu, "If there's anything you don't understand, just ask me."
It is almost April now, and there are only more than six months left before the announcement of the resumption of the college entrance examination policy. Su Qingyun still hopes that when that day comes, Xia Qiu will not be at a loss, but will be prepared to deal with it.
As for Ji Yue, she was certainly not worried. He was already good enough, and even if that day came, he would be able to deal with it calmly.
"That's it." Xia Qiu said casually.
She didn't take it too seriously. In her opinion, having good grades would only result in a better job assignment upon graduation, so the difference wasn't that big.
Su Qingyun frowned, sensing her perfunctory attitude. After thinking for a moment, he said, "Starting tomorrow, no, starting from this afternoon after school, you will come home with me and do your homework together. I will supervise you."
"Ah?" Xia Qiu was dumbfounded. "That's not the case, is it?"
"It's settled." Su Qingyun said without being able to refuse.
Xia Qiu immediately looked miserable. When doing homework with Qingyun, she could imagine the fear of being stared at.
It's so scary!
