Ever since Xiaoman's sister moved in, the life between the couple has been full of dullness. However, Xu Yang and Xu Man, brother and sister, seem to be very friendly to Wang Shuxue. They never cry in front of her, play happily together, and even forget about it.

My own father and mother.

Originally, Xu Mang would often laugh at Xiao Man about this matter, but now he has been marginalized by his children, making him full of jealousy...

The next night,

After Xu Mang took a shower, he glanced at the living room and saw that Wang Shuxue was still teasing the siblings, and then said: "That's almost enough... Xu Yang and Xu Man also need to go to bed, so don't bother the two little guys anymore.

, Go to bed early today, I will take you to the Department of Mathematics of Fuzhou University tomorrow."

"Fuda?"

"I remember, brother-in-law, you graduated from Fuzhou University, right?" Wang Shuxue asked excitedly: "By the way...brother-in-law, I have something to ask you. I study number theory...and what about the ABC conjecture?

How can we solve it?"

abc conjecture,

Xu Mang had heard a little bit that this was entirely a question of the relationship between prime numbers, which included many Diophantine problems, such as Fermat's last theorem. However, if the ABC conjecture could be proven, many problems might be solved.

Moreover, the ABC conjecture is different from Goldbach's conjecture. To explain the ABC conjecture to the public is a very huge and complex project.

"have no idea."

"I don't have time to solve this problem." Xu Mang said calmly: "I'm very busy... Studying mathematics is not my direction. As for mathematics problems, you can solve them yourself. By the way... I will take you with me tomorrow.

Go to Fuda and be more honest with me."

"knew!"

"Brother-in-law, you are so annoying...you are as verbose as my sister." Wang Shuxue said angrily: "Actually, it doesn't matter whether you go or not. You won't learn anything anyway. What I learned in Oxford, they

Definitely not, and if they can, I will definitely do it.”

"..."

"Okay, go back to your room quickly." Xu Mang said with a dark face.

"oh..."

Immediately afterwards,

Wang Shuxue kissed the siblings and reluctantly went upstairs. Facing Xiaoxue's departure, the siblings were a little reluctant to leave. But when they saw their father coming, a smile appeared on their little faces again, and they waved their hands in the air.

Standing, begging for a hug from his father.

"Walk!"

"Let's go find mom!" Xu Mang hugged the two little guys with a smile. As a result, the siblings didn't give Xiaoman face, so they started crying... and burst into tears. Xu Mang was very broken.

He said helplessly: "You two little ones, your mother worked so hard to give birth to you, and then you treat her like this?"

After coaxing for a while,

Xu Mang carried the child to the bedroom. At this time, Xiao Man was sitting on the bedside, reading the company's report on his tablet. When he saw his precious son and daughter, he hurriedly put down the tablet, opened his hand and shouted

Said: "Come, mom, give me a hug."

Not to mention,

The little guys were very considerate at this time. They just hummed a few times and came into Xiaoman's arms. Then...the siblings looked for the source of their lives in Xiaoman's body, but they couldn't find it...

"Hehe~"

"Don't look for it...Mom doesn't have this function." Xu Mang sat on the edge and said with a smile, "Dad has prepared a milk bottle for you."

The words fell,

Yang Xiaoman rolled his eyes and said angrily: "It's not all because of you and the child... I was already... already beginning to take shape, but I ruined it for you... You know I am...

Am I feeling somewhat sad? You idiot... made me so angry."

"..."

Xu Mang didn't know how to retaliate for a while. Indeed, he was greedy sometimes. Unexpectedly... It had only been less than four months, and Xiaoman had gone from a- to nothing.

"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. Once I'm used to your plainness in the past, and then let me accept you now, I'm actually a little uncomfortable with it.

."

"roll!"

"I don't know which bastard is shameless every night and says all kinds of witty words to tease me." Yang Xiaoman blushed slightly and said shyly: "To be honest... I actually quite like you teasing me. If you can

Can’t you flirt again today?”

"Forget it, forget it!"

"I am also a human being, not a farm cow." Xu Mang shook his head, closed his eyes directly, and took a long breath: "I am so tired... I have to take Xiaoxue to Fuda tomorrow. By the way, your sister is a bit arrogant.

I don’t know if you know that.”

"Um..."

"This little girl is a bit arrogant. She thinks she is the best in the world and no one is smarter than her." Yang Xiaoman said calmly: "She is different from your mango. She is a banana, you know what I mean."

"..."

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

"When I first met you, she went abroad..." Yang Xiaoman said: "It wasn't during that period that I often sent WeChat messages in class, just chatting with her. Anyway... you can be yourself

Sometimes her ideas will make you collapse."

Xu Mang shrugged and said calmly: "No matter how much you can collapse, it's all the same... I've seen people worse than your sister. She's just a child. Let's talk about it tomorrow... Let her see

See the true strength of Xu Yang Research Institute."

"Don't!"

"I'm afraid she won't go back after seeing her." Yang Xiaoman hurriedly shook his head and said seriously: "It's annoying to think about staying in our house from now on."

"Ouch?"

"Are you worried that your status will not be guaranteed?" Xu Mang said with a smile: "Wife... you also have today?"

"how?"

"There seems to be some story in your expression. Do you have any undue thoughts about me, Xiaoxue?" Yang Xiaoman glared and said angrily: "You scumbag!"

Xu Mang shrank his neck and said cautiously: "I am very picky, okay? Not just any good-looking woman can win me over. Look at so many single women in the world, why are they with you?"

get married?"

"Your taste!"

"You treat it with care!"

Suddenly,

Xiaoman felt as if she had been wiped with honey. In fact... To be honest, she was more than ten times more beautiful than Xiaoxue. She was just taller, and there was nothing else.

...

The next day,

Xu Mang took his children and his sister-in-law to the campus of Fuda. Along the way, his sister-in-law kept asking questions about this and that, which almost made Xu Mang collapse.

"Okay, okay!"

"That's it...are you one hundred thousand whys?" Xu Mang said with a dark face: "This far Abelian geometry...I really don't know, this most abstract branch of algebraic geometry, how can I

Maybe study it, and let me stress this again... I'm a theoretical physicist."

"..."

"cut!"

"If you don't want to say it, just say it. What's the point of emphasizing?" Wang Shuxue said with an unhappy face: "Brother-in-law, you are really bad."

"If it's bad, just be bad."

"I just ask you to shut up...it's so annoying." Xu Mang almost understood why Xiaoman was so disgusted with Xiaoxue. Who could stand this chattering?

soon,

Arriving at the Mathematics Department building of Fuzhou University,

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

"Xu Mang?"

"Ouch, ouch... the future math sweetheart is here too?" Director Ouyang Fei suddenly showed a friendly smile when he saw Xu Mang's child, hurriedly put down his work, walked to the stroller, and teased

With the siblings.

"Director Ouyang."

"Let me introduce... This is my wife's sister Wang Shuxue. She is a top student in the Department of Mathematics at Oxford University. She came back to China for vacation... I am thinking of bringing her here to accept the training here." Xu Mang smiled.

Said: “Let’s communicate and communicate with each other between Fuda and Oxford.”
