Qiao Yi could not believe it. He took it and flipped it open - it was completely filled with six pages of writing. As he flipped through and looked at Qiao Ying, he was shocked to the point his pupils shook when he saw the clear answer written at the end.
Qiao Yi was momentarily speechless, only able to stare blankly at Qiao Ying. But the blood in his body was silently boiling and clamoring.
It's done.
Countless teams had scrambled over each other, spent half a year racking their brains and wracking their wits. Even the mathematical genius Xu Zhiyi was unable to solve this problem. Yet his sister was able to do it in less than half an hour.
At this moment, the steps to the solution and the answer were in his hands. Qiao Yi's hands shook slightly from excitement holding the notebook.
Qiao Ying pinched Qiao Yi's handsome, fair face and said with a smile in her eyes: "Don't always have this reaction, it really makes it hard to handle."
Qiao Yi's mind buzzed loudly, even his neck turned red.
"Explaining the problem to you now would be a bit difficult. Wait until you're in college and I'll explain it to you then," Qiao Ying said.
As Qiao Yi looked at Qiao Ying, who had solved the problem with ease and barely any effort, he opened and closed his mouth wanting to say something but couldn't get the words out.
In the end, he silently returned to his room holding the notebook.
Sitting at his desk, Qiao Yi suddenly remembered something. He then took out his phone and clearly photographed each page before opening Peking University's math forum.
Peking University's math forum was lively every day with "mathematicians" from all over the world.
At this time, a Peking University junior math major had just logged off the account of the genius Xu Zhiyi and was idly browsing posts out of boredom.
Soon.
A brand new post caught his attention.
The post had no title. The content was just six photos.
The photos were of six pages of math scribbles.
Upon clicking in and looking, they were surprisingly the math problem that countless math geniuses had wrecked their brains trying to solve yet failed.
At first, he didn't have much of a reaction. After all, people turned this problem over every day and a quick search brought up piles of related posts and forums. He casually clicked to take a look.
As he read on, his facial expression gradually became serious.
He clicked to open the last photo and looked directly at the final answer without reading the solution process.
"Hmm, seems pretty legit."
Although people posted their pitiful attempts at solutions and had heated discussions every day, with some even diligently writing ten plus pages, seeing a complete solution process and answer posted all at once like this was the only one.
Without a second thought, he frantically @'d the genius Xu Zhiyi, who he had long admired, to come take a look. Then he shared it to various WeChat discussion groups.
It quickly attracted a lot of attention.
More and more Peking University students gathered in the comments section.
Within just over ten minutes, the post was pushed to the top and more and more people were alerted and flocked over.
[Has this damned problem finally been solved?]
[I've seen so many math gods show their calculations, this is the first time I'm seeing a complete process and result. There's hope, there's hope!]
[I don't understand math, but just looking at it seems amazing.]
[Without saying whether it's right or wrong, being able to write so much is already genius, right? Which math god hurry up and reveal yourself to accept my utmost admiration!]
[Forgive me for my lack of education, I'm just awestruck.]
[Got nothing else to say, math god please accept my knees.]
[Without any humility, I'll say these symbols make me unable to copy even if I tried.]
[This solution is a bit similar to what math god Xu showed before. Looks like it's definitely the right answer!]
[Math god isn't from our school right? Clicking into the profile shows sixteen years old, is that real?]
[Hurry and bring our lovely Principal and Xu genius over, I'm eager to know the answer.]
[Yet another day I'm just making up numbers in this world, completely given up.]
[Math god, can you please say something?]
[Looks like our Peking University is about to gain either an outstanding student or a genius teacher.]
[Poster above think bigger, just directly add another vice principal.]
[Poster above has small aspirations. For being able to solve this problem, who cares about those things?]
Qiao Yi was just browsing some test papers to calm down. When he opened the forum to check his post again, it had already gained the attention of waves of Peking University students.
There were already over two thousand comments accumulating at a frightening speed, increasing by tens of comments with each refresh.
There were also hundreds of private messages.
It had only been twenty some minutes. If it attracted the appearance of Peking University's president or Xu Zhiyi, this post would probably explode.
Qiao Yi hadn't expected it to be discovered by everyone so quickly, much less such a big reaction.
It seemed everyone's enthusiasm for this problem had never waned.
Xu Zhiyi was currently engrossed in his lab, deeply immersed in his research. The door was suddenly banged open.
The old professor rushed in, impressive for his seventies.
The interrupted Xu Zhiyi deeply furrowed his brows, his handsome face clearly showing anger.
Just as he was about to flare up, he heard the old professor say, "Little Yi, don't be busy. The problem's been solved."
Xu Zhiyi immediately lifted his head, the exhaustion from two days without sleep instantly disappearing without a trace.
"It's solved?"
There was no need to even ask which problem the old professor was talking about.
"It's solved. Take a look."
The old professor held his phone up to Xu Zhiyi's face. His wrinkled old face was flushed red, unable to conceal his excitement and elation.
Qiao Yi no longer had the heart to study and was browsing the comments, looking at the Peking University students' worshipful words. He couldn't help feeling excited in his heart, as if he also had a share in these honors.
"Sis can get into Peking University by recommendation now." Qiao Yi thought.
Just as he was about to show Qiao Ying, his mother Li Lilian called him to eat dinner.
Only then did he realize the sky had already darkened.
Qiao Yi had no choice but to exit the forum, perfectly missing Xu Zhiyi's private message.
At the dinner table, Qiao Yi had originally wanted to tell the whole family about Qiao Ying's high possibility of getting into Peking University by recommendation in front of everyone, to make Father happy and let Mother and Second Sister know Eldest Sister wasn't as useless as they thought.
But before he could speak, Mother Li Lilian used her chopsticks to knock against her bowl. "When are you getting the money from the construction site? There are so many mouths to feed at home, the rice bucket is almost empty. Relying on my two thousand plus salary, how can I support so many mouths?"
Qiao's Father was also worried about the delayed wages. "The foreman said it would be this mid-month. I'll ask again then."
"Mid-month? What day is it today? Who knows if mid-month won't become end of month again." After Li Lilian spoke, she looked at Qiao Ying, "Since you can earn money, shouldn't you contribute something to the family after we raised you and spent so much to support your schooling and nurture you? You eat from the family and use the family's things, now that you have skills and ability to earn money..."
This was her real motive.
Qiao's Father wanted to say something but stopped, only silently looking at Qiao Ying in the end.
Qiao Ying put down her chopsticks without even lifting her head. "Account."
Li Lilian's eyes lit up and she immediately took out her phone to pull up her payment code, beaming ear to ear. "Scan here to directly transfer to Mom's WeChat."
Qiao Ying took out her phone.
Qiao Lingling, who had been quietly eating, couldn't help but sneak a glance at Qiao Ying's expensive phone.
After the money was transferred, Li Lilian held it up to her face. The moment she saw the amount, her smiling face did a complete one eighty degree flip.
"Only two thousand? Your one phone is over ten thousand yuan, plus your computer, new clothes and shoes. You only give the family two thousand?"
"This month's food expenses for me and Qiao Yi." Qiao Ying didn't even want to say another word more than necessary.
Qiao Lingling also snuck a peek at Qiao Yi.
But Qiao Yi was looking at Qiao Ying.
"Food expenses? For two? Do you know how expensive oil, rice, and everything is nowadays? Two thousand yuan for two people, how is that enough!"
Qiao Ying lifted her eyes and coldly looked at Li Lilian, scaring her into immediately shutting up with just one look.
