Since Xiaoman's sister moved in, the life between husband and wife has been full of blandness, but Xu Yang and Xu Man, sister and brother, seem to be very friendly to Wang Shuxue, never cry in front of her, play together happily, and even forget their father and mother.

Originally, Xu Mang would often use this matter to laugh at Xiaoman, but now he is also marginalized by the child, which makes him full of jealousy...

The next night,

Xu Mang took a shower and glanced at the living room, and saw that Wang Shuxue was still teasing the sister and brother, and then said, "It's almost enough... Xu Yang and Xu Man are also going to sleep, don't toss the two little guys anymore, go to bed early today, and I'll take you to the Department of Mathematics of Fuda tomorrow. ”

"Fuda?"

"I remember brother-in-law, you came out of Fuda, right?" Wang Shuxue asked excitedly, "By the way... My brother-in-law has something I want to ask you, I study number theory... How can the ABC conjecture be solved?"

ABC conjecture,

Xu Mang has heard that this is entirely a question of the relationship between prime numbers, which includes many Diophantine problems, such as Fermat's theorem, but if the ABC conjecture can be proved, many problems may be solved.

Moreover, the ABC conjecture is different from the Goldbach conjecture, and trying to explain the ABC conjecture to the public is a very large and complex project.

"I don't know. ”

"I don't have time to deal with this either. Xu Mang said indifferently: "I'm quite busy... Studying mathematics is not my direction, as for the problems of mathematics, you can solve them yourself, right... I'll take you to Fuda tomorrow, and you can be honest with me. ”

"Got it!"

"Brother-in-law, you're so annoying... It's as verbose as my sister. Wang Shuxue said angrily: "Actually, it's the same whether you go or not, you can't learn anything anyway, what I learned in Oxford, they definitely won't, and they will, I will definitely do." ”

“...”

"Alright, hurry back to your room. Xu Mang said with a dark face.

"Oh..."

Followed by

Wang Shuxue kissed the sister and brother, reluctantly went upstairs, in the face of Xiaoxue's departure, the sister and brother were a little reluctant, but when they saw their father coming, a smile appeared on their little face again, waving their hands in the air, begging their father to hug.

"Let's go!"

"Let's go to Mom!" Xu Mang smiled and picked up the two little guys, but the sister and brother didn't give Xiao Man face, and they cried at the beginning... Wow wow wow burst into tears, Xu Mang was very devastated, and said helplessly: "You two little things, my mother worked hard to give birth to you, and the result was like this?"

Coaxed for a while,

Xu Mang came to the bedroom with the child in his arms, at this time Xiao Man was sitting at the head of the bed, looking at the company's report with a tablet, and when he saw his baby son and baby daughter, he hurriedly put down the tablet, opened his hand and shouted: "Come, mom hug." ”

Not to mention,

The little ones were quite face-saving at this time, but they just snorted a few times, and then came to Xiao Man's arms, and... The sisters and brothers looked for the source of their life in Xiao Man's body, but they didn't find it...

"Hey~"

"Don't look for it... Mom doesn't have this feature. Xu Mang sat on the side and said with a smile: "Dad has prepared a bottle for you." ”

Words fall,

was blinded by Yang Xiaoman, and said angrily: "It's not all because you robbed the child... Originally, I was... It's already starting to take shape, and it's ruined for you... Do you know how sad my heart is, old lady? Big idiot... I'm. ”

“...”

Xu Mang didn't know how to fight back for a while, indeed sometimes he was greedy, and he couldn't think of it... It's only been less than four months, and Xiao Man has gone from A- to none.

"Ahem!"

"Do you know why I like to eat Lay's Original Potato Chips?" Xu Mang said seriously: "Because I don't like those bells and whistles, when I get used to the flatness of your past, and then let me accept the current you, it's actually a little uncomfortable." ”

"Get out!"

"I don't know which bastard is shameless and says all kinds of witty things to tease me every night. Yang Xiaoman blushed slightly and said shyly: "To be honest... Actually, I like you to tease me, can you tease me again?"

"Forget it!"

"I'm also a human being, not a farming cow. Xu Mang shook his head, closed his eyes directly, and took a long breath: "I'm so tired... I'm going to take Xiaoxue to Fuda tomorrow, and your sister is a little arrogant, I don't know if you know. ”

"Hmm..."

"This little girl is a little arrogant, she feels that she is the best in the world, and no one is smarter than her. Yang Xiaoman said indifferently: "It's not the same as your mango, she is a banana, you know." ”

“...”

"Oh. Xu Mang nodded and said seriously, "When did you go abroad?"

"When I first met you, she went abroad..."Yang Xiaoman said: "Isn't it that time, I often send WeChat messages in class, just chatting with her, anyway... You do your own thing, and sometimes her notions can break you. ”

Xu Mang shrugged his shoulders and said calmly: "How far can it collapse, in fact, it's all the same... I've seen anyone who is even more unbearable than your sister, she's just a pediatrician, let's talk about it tomorrow... Let her see the true strength of the Xu Yang Research Institute. ”

"Don't!"

"I'm afraid she won't go back when she sees her. Yang Xiaoman hurriedly shook his head and said seriously: "In the future, I will be in our house, and I feel annoying to think about it." ”

"Huh?"

"Are you worried that your status is not guaranteed?" Xu Mang said with a grin: "Wife... Do you have today?"

"How?"

"Look at your expression, it seems that there is a story, do you have any thoughts about me Xiaoxue?" Yang Xiaoman glared and said angrily: "You scumbag!"

Xu Mang shrunk his neck and said cautiously: "My vision is very picky, it's not a casual woman who can take me down, you look at so many single women in the world, why did I marry you?"

"You're good!"

"You taste it with your heart!"

Suddenly,

Xiao Man's heart is like smearing honey, in fact... To be honest, she is more than ten times better looking than Xiaoxue, she just grows taller, and nothing else.

...

Following

Xu Mang took the child and sister-in-law to the campus of Fuda University, and along the way, the sister-in-law either asked or asked that, which almost made Xu Mang collapse.

"Alright, alright!"

"So be it... Are you 100,000 why?" Xu Mang said with a dark face: "This far Abel geometry... I really don't know, how could I possibly study this most abstract branch of algebraic geometry, and I emphasize it again... I'm a theoretical physicist. ”

“...”

"Cut!"

"If you don't want to say it, don't say it, emphasize something. Wang Shuxue said with an unhappy face: "Brother-in-law, you are really bad." ”

"Bad is bad. ”

"Just keep your mouth shut... Sick of it. Xu Mang almost understood why Xiao Man was so disgusted with Xiao Xue, who could stand this chatter?

soon

When I arrived at the Mathematics Department Building of Fudan University,

Xu Mang pushed the stroller and took his sister-in-law and ran directly to the office of the head of the mathematics department.

"Xu Mang?"

"Oops... The future math lady is also here?" Director Ouyang Fei saw Xu Mang's child, and immediately showed a kind smile, hurriedly put down his work, walked to the side of the stroller, and teased the sister and brother.

"Director Ouyang. ”

"Introduction... This is my wife's sister Wang Shuxue, a top student in the Department of Mathematics at Oxford University, who returned to China for a vacation... I thought about bringing her here and getting her to be nurtured here. Xu Mang said with a smile: "Between Fuda and Oxford, communicate together. ”

"Director Ouyang, hello. Wang Shuxue greeted respectfully.

"Oh?"

"Are you Wangshuxue?" Director Ouyang was stunned for a moment, couldn't help but show a smile, and said: "I didn't expect this world to be so small, and it was all a family... Xu Mang, why are all geniuses in your family?"

Xu Mang: ???

What genius?

She's a genius, huh?

Startled, repeatedly jumping sideways, this is also a genius?

"Last year, I won the third place in the International Collegiate Mathematics Competition, and I don't think I need any training for this strength. Director Ouyang smiled: "But it's okay to communicate with each other." ”

"Isn't it awesome?" asked Xu Mang.

“...”

"Brother-in-law!"

"I'm really good!" Wang Shuxue frowned and said angrily: "Don't always look down on me. ”

"Oh..."

Xu Mang didn't know much about some competitions in the field of mathematics, he didn't participate in much, and he was not banned from participating in international competitions, and he later embarked on the road of physics, and mathematics was more reduced to a calculation tool.

afterwards

Xu Mang directly sent his sister-in-law away, asked her to visit a laboratory, and took the child to chat with Director Ouyang.

"Xu Mang?"

"Train Xu Yang and Xu Man well, you must study mathematics in the future!" Director Ouyang said: "The thing I regret the most in my life is that I didn't recruit you and your wife into the Department of Mathematics, and now I don't want to miss Xu Yang and Xu Man." ”

"Hey, hey!"

"Let's talk about it later... First pass the level of nine-year compulsory education. Xu Mang sighed and said silently: "I'm very worried now... The child does not learn and has no skills, mainly because the family conditions are too superior. ”

"It's about parental education. ”

"But I'm very confident in your family's genes!" Director Ouyang smiled: "Parents are so powerful, children will not be far behind, dragons give birth to dragons, phoenixes give birth to phoenixes, and mice give birth to burrows in the ground, this is not a joke, this is a cruel reality." ”

"A person's growth is particularly influenced by his family..."Ouyang said: "Cultivate well, don't distort the skill tree, and be sure to point out the mathematical talent." ”

In response to Director Ouyang's words,

Xu Mang fell silent, but in the end he chose to be a lying and winning parent, letting Xu Yang and Xu Man play freely, and sometimes forcing them to backfire.

Then

The phone rang,

It turned out that the sister-in-law had an academic dispute with someone else, and the quarrel was inseparable!
