Originally, Tong Lingling was going to ask her brother-in-law how he solved these problems in a short period of time, and what skills were used, you must know that these problems were thought up by authoritative people in the field of mathematics, even if they are so-called mathematical geniuses, it takes a period of hard thinking and meditation.

As a result, in the hands of my brother-in-law, it seems that he has not survived for a long time, and the longest is probably the first question, and he thought about it for about five minutes before he started writing.

But compared to his cousin, these five minutes of thinking time are simply non-human... My cousin thought about it for half an hour, but she still didn't come up with a solution, you have to understand... My cousin, as a physicist, is ridiculously strong in mathematics.

At this moment,

This outrageous scene appeared...

Tong Lingling looked at her cousin Liu Yun'er, lying on her cousin-in-law Lin Fan, her cousin's arm wrapped around her cousin-in-law's neck, and her cousin-in-law also hugged her cousin's waist... The heads of the two men were pressed tightly together, constantly writhing...

In a flash

The face is distorted, and there is only one thought in the head... Want to go home!

Tong Lingling was so angry that she exploded, and said angrily: "Hey!

Lin Fan still had some sense, and was about to let go of his mouth, but Liu Yun'er felt Lin Fan's retreat, and clasped the back of his head with one hand to prevent this big pig's trotters from escaping, for the big goblin, it has only been twenty seconds now, and there are at least ten seconds left to kiss.

"Hey!"

"Hurry up and let go of me!" Tong Lingling roared.

however

In the face of Tong Lingling's roar, Lin Fan and Liu Yun'er were indifferent, and still hugged each other tightly.

Tong Lingling exploded directly, stepped forward angrily and grabbed one of her cousin's arms, and said angrily: "Hurry up and let go of me... I can't stand it anymore!"

ultimately

Lin Fan and Liu Yun'er were relieved, but the big goblin was still lying in Lin Fan's arms, enjoying the warmth given by his man.

Then

Tong Lingling glanced at her cousin, her face was full of happiness, and she was very angry... Look at his brother-in-law, he is also a raccoon dog.

“...”

"I want to go home!" Tong Lingling said with an aggrieved face: "I have to go home now!"

Lin Fan and Liu Yun'er were stunned for a moment, looking at their cousin's aggrieved appearance, they suddenly felt a trace of pity, Liu Yun'er felt that her little sister was also quite miserable, she had just broken up with her boyfriend? And then return home with a lovelorn mood? was first beaten up by Lin Fan academically, and was also shown his affection.

"This..."

"It's so late? Do you want my sister to send you back tomorrow?" Liu Yun'er said helplessly.

"Don't!"

"I'm going home now!" Tong Lingling pouted? With an angry face, he said, "I don't want to stay here anymore... You guys are too bullying!"

Words fall,

Tong Lingling's eyes began to have tears? She was so angry that she choked.

At this time, Liu Yun'er hurriedly got up from Lin Fan's arms and directly hugged Tong Lingling in her arms? Said helplessly: "Sister is wrong... Don't cry, don't cry... Sister apologizes to you? How about my sister accompany you to buy dolls tomorrow?"

“...”

"Then can you sleep with me at night?" Tong Lingling said aggrievedly.

"Of course!" Liu Yun'er nodded.

"That..."

"Can you ask my brother-in-law to teach me how he solves these problems?" asked Tong Lingling.

Liu Yun'er pondered for a moment and said to Tong Lingling: "This... Ask your brother-in-law yourself. ”

As soon as the voice fell,

Tong Lingling broke free from Liu Yun'er's embrace? With an expectant face, he asked, "Brother-in-law... Can you teach me? How did you solve these problems? Did you use any techniques?"

"Yes. ”

Lin Fan nodded with a smile and said seriously: "Actually, it's not a skill, your sister knows..."

“...”

Liu Yun'er was already wondering, why was Lin Fan able to analyze the meaning of the topic so quickly, and the guy started cheating again? He is not solving the problem seriously, but is figuring out the plan of the questioner? Because there is a pattern to any topic.

"You..."

"Forget it. Liu Yun'er said helplessly: "You just tell her how to solve it." ”

"What's there to say about this, it's just a bit of a broken topic. "Lin Fan is still lying on the sofa? said indifferently: "If she wants to discuss academic issues with me, I would be quite willing... I also know a lot about topology. ”

Hear your brother-in-law's words? Tong Lingling was taken aback? He looked at him with horror on his face.

No...

Does he even know that?

"Don't look at your brother-in-law's ostensibly just a library administrator? In fact, he used to be a researcher on the theory of relativity. Liu Yun'er explained: "There is a little research on topology. ”

Tong Lingling came back to her senses, glanced at her lazy brother-in-law, and then at her cousin sitting beside her, and cautiously asked Lin Fan, "Brother-in-law, you are so awesome, why did you find my sister as your girlfriend?"

Hearing this,

Liu Yun'er almost didn't get angry, what is he bullish or not, does it have anything to do with finding himself as a girlfriend?

Am I not worthy to be his girlfriend?

Suddenly

Liu Yun'er grabbed Tong Lingling's ears and asked angrily, "What do you mean by this little girl?" Do you think that my sister and I are not worthy of your brother-in-law?"

"Not really!"

"My brother-in-law is so good, look at you so badly, except for being beautiful, you are nothing good..."Tong Lingling said stubbornly.

Words fall,

Tong Lingling felt a burst of pain and hurriedly said, "I was wrong..."

"Humph!"

"Almost... You can go back with me. Liu Yun'er glanced at the time, and said to her cousin indifferently: "If there is something to talk about tomorrow." ”

"Oh..."

...

Eleven o'clock in the evening,

Liu Yun'er and her cousin Tong Lingling were lying on the same bed, and Tong Lingling seemed to have opened the conversation box, telling her cousin about the various things she had encountered this year, including the troubles and pressures she had encountered in academics.

"Sister?"

"How did you and your brother-in-law meet?" Tong Lingling turned around and asked curiously.

“...”

"I met on a blind date. Liu Yun'er was sending WeChat messages with Lin Fan and said casually.

"Huh?"

"Such a cliché start?" Tong Lingling said with a little disappointment: "It's boring... Not interesting at all. ”

Liu Yun'er put down her phone and said angrily: "You think you are filming a TV series?"

“...”

"I thought you and your brother-in-law knew each other because of a scientific research. Tong Lingling said helplessly: "It turned out to be a blind date... But it's normal to think about it, sister, you're twenty-nine, and if you don't go on a blind date, it's estimated that it will be cool. ”

"Don't mention my age again, or I'll go to bed on the couch. Liu Yun'er said angrily: "Did you hear that?!"

"Oh..."

Tong Lingling nodded, her big eyes flickered a few times, and she asked cautiously, "Sister, do you have any... The secret to getting bigger? I found that you seem to have expanded a little more, is it the relationship between brother-in-law? ”

"Hey!"

"Lingling!"

"That's all you learned abroad?" Liu Yun'er said angrily: "Don't learn good knowledge, learn some messy things." ”

"I've learned a lot too, you see... You can't even do a single question. Tong Lingling said with a smile: "Actually, I am very good. ”

"I..."

"I'm busy with work. Liu Yun'er glanced at her and said indifferently: "But... You said that you are very good, I have a little objection, your cousin-in-law's current state is to fish at work, start playing games after work, and never touch books, but you were crushed by him, do you think you are still good?"

Suddenly

Tong Lingling was speechless and didn't know how to refute.

"Sister?"

"What the hell is my cousin-in-law... What kind of strength?" Tong Lingling asked curiously: "Why is he so good, willing to work in the library, what is his situation?"

“...”

"I don't know. Liu Yun'er said helplessly: "Whenever I ask about these things, your brother-in-law will put on a face for me, and then I will lose interest, so I will as... It didn't happen, but according to my guess, he used to be a researcher on a top-secret project. ”

"I guessed that I was calculated, and I quit halfway, and this kind of project doesn't keep a file, and even hides my identity, so... That's what happened to your brother-in-law. Liu Yun'er explained: "Of course... That's all my guess. ”

"Uh..."

"Sounds reasonable. Tong Lingling nodded.

suddenly

Liu Yun'er's mobile phone rang, and it was a WeChat prompt tone.

The big goblin hurriedly glanced at the content on it, and Lin Da Pig's trotters only wrote a few words... Do you sleep together?

Then

Liu Yun'er pursed her lips and silently replied to Lin Fan with a message...

Yun: Wait a minute, Xiao Nizi hasn't slept yet.

In fact

Liu Yun'er was already a little impatient, the original plan was to let her cousin Lingling sleep alone, and she lay in Lin Fande's arms, but... In the end, it turned out to be like this.

"I slept. Liu Yun'er turned off her mobile phone and said silently: "You also go to bed early." ”

"Oh..."

Tong Lingling silently closed her eyes, and the two women were lying on a big bed, listening to each other's breathing, but each had a ghost in their hearts.

Liu Yun'er hoped that Tong Lingling would go to bed early so that she could sneak into Lin Fan's bedroom, but... Tong Lingling, a little girl, is not a fuel-efficient lamp, and she has long known her cousin's routine.

As for why she didn't expose it, she just wanted to give her cousin a fatal blow at a critical moment and let her cousin get out of trouble.

Ten minutes later,

Liu Yun'er opened her eyes and asked in a low voice, "Lingling?"

She was met with silence.

Liu Yun'er hesitated for a moment, gently lifted her quilt, and then tiptoed towards the bedroom door.

At this moment,

Tong Lingling suddenly opened her eyes and asked curiously, "Sister, where are you going?"

This sudden inquiry almost scared Liu Yun'er to death, and suddenly looked at her cousin with a frightened face and asked, "You... Why don't you sleep yet?"

"I slept all afternoon... I can't sleep a little now. Tong Lingling then said seriously: "Sister, you haven't answered me yet, where are you going?"

Time

Liu Yun'er didn't know how to answer her.

"Are you going to find my brother-in-law?" Tong Lingling showed a wicked smile: "Lonely?"

Liu Yun'er glanced at each other, and said angrily: "The lonely and lonely person is you, I will go to my man's arms now, you lie down slowly alone!"

"Goodbye!"
