Tong Lingling never expected that while she was eating... she saw this outrageous scene. She opened her mouth forcefully, and poured dog food into it desperately... and even soaked it.
Overconcentrated sulfuric acid.
"you..."
"Can you be a little more reserved?" Tong Lingling said angrily with a dark face: "Can you treat me as a human being? I am also flesh and blood, and I also have emotions...I just broke up not long ago."
"Your brother-in-law often feeds me like this." Liu Yun'er ate the fish meat that Lin Fan brought and said calmly: "I can't change the habits between your brother-in-law and I just because of you, right?"
Tong Lingling was speechless, not knowing what to say.
"I'm furious..."
"If I had known it... I wouldn't have come." Tong Lingling said angrily, "I'm so annoyed."
"I didn't ask you to come." Liu Yun'er said seriously: "How about... I take you home now?"
"..."
"never mind."
"I'll go home in two days." Tong Lingling picked up a piece of plain-cut chicken and dipped it in some soy sauce, and said seriously: "Sister...after dinner, I want to challenge you. Didn't you take Putnam Mathematics?"
The top five results in the competition?"
Hearing these words,
Liu Yun'er was not surprised. She had long known what Lingling came back to do, just to defeat herself. This was also the agreement she had made with her in the past. As long as she defeated herself... she would buy her a doll. The result.
..More than ten years have passed and there has never been a victory.
However,
Liu Yun'er has already felt the pressure, because in these short two years, Lingling's progress has been too fast. When she defeated her last year, she won the final victory in a narrow victory.
"Your sister, I... have become a little lax in this regard, and I am now engaged in the field of physics. Even if you defeat me, there is nothing worth bragging about." Liu Yun'er said calmly: "But...
I accept your challenge, but...I have to add a condition."
"speak!"
"What conditions?" Tong Lingling asked.
"Not only do you have to defeat me, but you also have to defeat your brother-in-law, otherwise... I won't give you this doll," Liu Yun'er said.
Brother-in-law?
Just him?
Tong Lingling was stunned for a moment and said helplessly: "Sister...the conflict between us sisters has nothing to do with my brother-in-law, right? Besides...my brother-in-law doesn't understand."
The words fell,
Tong Lingling looked at Lin Fan and said awkwardly: "Brother-in-law? If I say this...will you be angry?"
"No." Lin Fan smiled and ate the food in silence.
"oh..."
"Then I will continue." Tong Lingling looked at Liu Yun'er and said seriously: "Sister... I think you are trying to drag your brother-in-law into trouble."
"What do you mean by pulling the strings?" Liu Yun'er rolled her eyes and said expressionlessly: "Ask your brother-in-law if he wants to participate. If he doesn't want to, I won't force him."
As soon as the words fell,
Tong Lingling asked hurriedly: "Brother-in-law? Do you want to wade into the muddy water?"
"You can give it a try." Lin Fan said with a smile, "I'm pretty good at math."
"..."
"Brother-in-law!"
"This is not a math question for the college entrance examination. This is... a problem that my sister and I need to solve. It extends to science. We will apply it to... such as functional analysis, statistics, operations research, and dynamic systems.
Topology and so on." Tong Lingling explained.
"oh..."
"Try it." Lin Fan still said with a smile on his face: "I have received perfect scores in mathematics before, so... it shouldn't be a problem."
Tong Lingling was speechless? We are really not a family? She is as stubborn as her sister if she doesn't enter the same family.
"well..."
"Then it's up to you? I hope you won't collapse by then." Tong Lingling sighed and said silently.
soon,
Is dinner ready for three people?
Then Lin Fan put away the dishes and prepared to give them a bath. At this moment... someone came in quietly? He gently hugged Lin Fan from behind and felt the pain through his back.
With a strong sense of oppression, Lin Fan knew that the person coming was anyone.
"Where's your sister?" Lin Fan asked.
"Looking for a topic." Liu Yun'er said.
"You're not looking for it?"
"Well..." Liu Yun'er nodded and said softly: "Xiao Nizi has made too rapid progress in the past two years? And I have been engaged in physics research? How can I have time to study mathematics? Let her win once."
The words fell,
Liu Yun'er said seriously: "But... you must crush her!"
"The little girl has a pretty good personality, isn't it necessary?" Lin Fan said casually while washing the dishes.
"What do you know!"
"The condescending tone Xiao Nizi spoke to you just now? I felt very uncomfortable when I heard it." Liu Yun'er said angrily: "When will it be my man's turn to teach you, but... I don't want to take out my sister's
To educate her with your posture? But I hope you will use your own strength to completely convince her."
"..."
"What if your sister falls in love with me?" Lin Fan said with a smile: "Isn't this how all bloody dramas are played? When the brother-in-law shows his domineering spirit? The sister-in-law's eyes sparkle with stars, and she praises the brother-in-law for being so handsome? Then it's staged
An exciting love triangle."
The words fell?
Lin Fan felt severe pain coming from his thigh.
"rest assured."
"First of all, am I prettier than her? She is self-aware, and secondly, you can't catch her eye. You're too lazy to do anything... Who is willing to raise you except me?" Liu Yun'er said angrily.
Lin Fan smiled awkwardly, as if...this was indeed the case.
At this time,
Tong Lingling's shouts came from the living room.
"sister!"
"I'm ready."
"..."
"I understand." Liu Yun'er shouted helplessly, and then said to Lin Fan: "I'll go over first...you wash slowly."
The words fell,
Liu Yun'er left the kitchen and came to the sofa in the living room. Then she saw a piece of white paper on the coffee table, with four simple questions written on it.
"What four questions?" Liu Yun'er frowned.
"Two of you and two brothers-in-law, or four of you and zero brothers-in-law." Tong Lingling said with a smile: "Sister? What about yours?"
"I'm too lazy."
"Just do it... As long as you make three mistakes, you win. What do you think?" Liu Yun'er asked.
"OK!"
Tong Lingling nodded, then handed Liu Yun'er a pen and said with a smile: "Sister... let's get started."
When Liu Yun'er took the pen and began to read the questions seriously, she realized... why did the little girl next to her suddenly return to China? This was a long-planned plan. The above questions must have
She didn't think of it herself.
This difficulty...
Equivalent to the highest level of difficulty in the Putnam Mathematics Competition and the International Collegiate Mathematics Competition.
"well?"
"I said you, little girl, are you doing this for your sister's doll?" Liu Yun'er glared at Tong Lingling and said angrily: "These questions of yours... must have been thought up by your tutor, right?
?”
"hey-hey..."
"I have been losing for more than ten years, what's wrong with letting me win once?" Tong Lingling said with a proud look on her face: "These questions were thought up by my mentors and I."
Although Liu Yun'er was very angry, she had no choice but to continue to do it. Of course... Liu Yun'er also wanted to test herself and see how much she had regressed in mathematics. She felt that she had regressed a lot.
, after all many years ago... Liu Yun'er had already led multiple research projects.
As the leader of a research project, she does not need to participate in the whole process, but plays an absolute role in several key issues, such as... to overcome a certain problem, formulate a rough solution, and then
Assign tasks to the following researchers.
first question,
Regarding the direction of group theory, this is what Liu Yun'er is good at, but she soon discovered that Xiao Nizi was not so kind, because there were many contradictions in this issue.
at this time,
Lin Fan walked out slowly and looked at the two sisters sitting together. He did not approach them and talked to them. Instead, he went to the computer desk and started playing games.
For mathematics,
Lin Fan has never been very interested in it since he was a child, but physics requires mathematics, so Lin Fan had to learn mathematics, and then accidentally won some mathematics awards. However, compared with his achievements in physics, Lin Fan
His achievements in mathematics are not high.
But this does not mean that Lin Fan is weak in mathematics. On the contrary... his mathematical talent is very strong.
Just opened the game,
As a result, Dabao and Erbao slowly walked to Lin Fan's feet, rubbed them gently a few times, and then suddenly jumped onto Lin Fan's lap. The two cats each occupied one leg and lay quietly on it.
actually,
Lin Fan has regarded Dabao and Erbao as his own family, and they have the same status as Liu Yun'er, and Lin Fan also hopes that...when the little goblin is born in the future, Dabao and Erbao can get along happily with the little goblin.
at the same time.
The big goblin is racking her brains, thinking of solutions to the problems in front of her, but she just can't think of any. She can't even solve a single problem. This has obviously exceeded her understanding of mathematics, and she is already studying pure mathematics.
"well..."
"never mind."
"Can I admit defeat?" Liu Yun'er sighed, silently put down the pen in his hand, and said to Tong Lingling, who was smiling brightly next to him: "You are so good...sister, I lost."
"yeah!"
"I finally won!"
Hearing that her sister admitted losing, Tong Lingling jumped up with excitement. Although...the method of winning was a bit shameless, and she asked those math experts to help her solve the problem, but think about it...she was bullied by her sister.
After more than ten years, it’s time to win again.
"Hello!"
"I lost...but your brother-in-law hasn't lost yet!" Liu Yun'er said angrily, "Are you too happy too early?"
"..."
"sister?"
"You really won't let your brother-in-law do it, right?" Tong Lingling said in a low voice: "Save some face for your brother-in-law..."
Liu Yun'er pursed her lips. In fact, she was a little panicked at this moment. This little girl asked the authorities in the field of mathematics to ask questions. You can imagine the difficulty... Yes, the big idiot is indeed very strong in mathematics, but also
Not strong enough to reach the authoritative level, right?
At this time,
Lin Fan had just finished the game, took off his headphones, looked back at the sofa, and found that it seemed to be over.
"well?"
"it's over?"
"What's the final result?" Lin Fan asked curiously.
"hey-hey!"
"My sister is completely defeated!" Tong Lingling said excitedly.
Lin Fan was stunned for a moment. He originally thought that Liu Yun'er would be defeated, but he didn't expect that he would be completely defeated in the end.
He picked up the two cats and put them on the ground, then stood up and walked to the sofa. He bent down slightly and glanced at the question on the white paper, and he was immediately shocked.
Damn it!
The little girl is coming with bad intentions!
at this time,
Liu Yun'er saw Lin Fan's silent look and knew that even a stupid person couldn't solve these problems, but she didn't blame him in her heart. She could only blame herself for being careless.
Sudden,
Lin Fan looked at the big goblin and asked seriously: "Baby, do you want to win?"
