Three o'clock in the afternoon,

Liu Zhongtao received a call from his daughter and was told to leave work early for Lin Fan later, as for what reason... Liu Yun'er didn't say it, but Liu Zhongtao smiled knowingly, what other reason could there be?

subsequently

Lin Fan received a call from Liu Yun'er, and then ran to Liu Zhongtao's office, thinking that leaving work early would be rejected, but he didn't expect it to go so smoothly.

When I got to the old place,

Lin Fan stood there and waited for a while, then saw a white Audi car coming.

"What's the matter?"

The first thing he did when he got into the car, Lin Fan fastened his seat belt and asked with a confused face: "I haven't woken up yet..."

"Didn't you say yesterday that you wanted to meet my girlfriend? Liu Yun'er said indifferently: "Then I will arrange for dinner this afternoon, first... Then find a quiet place for you to talk. ”

“...”

"It's not... Didn't you let me meet your best friend before?Why did you suddenly arrange to meet again?" Lin Fan asked curiously, "And I feel that your arrangement... It's kind of like giving me a blind date. ”

"Look at your size!"

"You think you and my best friend can be alone? I'm going to be with you all the time. Liu Yun'er said angrily: "Lest my sister be poisoned by you." ”

"Don't worry!" Lin Fan patted his chest and said seriously: "I will always only take advantage of you!"

These words made Liu Yun'er almost vomit blood, and said with an annoyed face: "You... You... Can you talk to someone?"

Lin Fan smiled and did not continue to speak.

"Ugh..."

"After meeting my best friend, you try to behave better, don't talk about it..."Liu Yun'er said seriously: "And... Don't talk about things in life, including anything related to me, just about gravitational analogies. ”

"Oh..."Lin Fan nodded, and couldn't help but hit a hatchet.

“...”

Liu Yun'er looked at Lin Fan's mental state and couldn't help but ask, "You... Did you get enough sleep during the day?"

"It's okay. ”

"Go to bed early tonight... I'm old, and I can't afford to stay up all night. Lin Fan was paralyzed in the co-pilot's seat, and said weakly: "But I still have to go for a run..."

"Don't run. ”

"Go to bed early. Liu Yun'er said.

"No!"

"I have to go for a run. Lin Fan shook his head and said seriously: "You must take advantage of you." ”

Liu Yun'er was so angry that she felt that she was born to be taken advantage of by him, and she was obviously tired to the point of dying, but she thought about taking advantage of it in her head.

It's so angry!

"Hey!"

"I said you..."Liu Yun'er just asked Lin Fan, can you stop bullying yourself, but when she saw him sleeping, her heart softened for a while, and she sighed helplessly.

I don't know what to start with, Liu Yun'er feels that this guy next to her will deeply hold her heart with every move.

And what about him?

Is he also implicated in his heart?

Definitely too!

Every time Liu Yun'er thinks of the nervous look of the stupid guy next to her when she was sick, and the meticulous care she took afterwards, it will make her heart swell with a burst of sweet emotions.

Long

At half-past four,

Liu Yuner silently started the car and went to her best friend's unit.

When she was about to arrive at the door of Song Yuxi's unit, Liu Yun'er parked the car on the side of the road and said to Lin Fan beside her: "Alas... Wake up!"

“...”

"Huh?" Lin Fan opened his hazy eyes and asked curiously, "What's wrong?"

"You sit in the back. Liu Yun'er said.

"Why?" Lin Fan asked.

"Don't ask!"

"Anyway... Sit in the back anyway. Liu Yun'er said.

"Oh..."

Lin Fan didn't know what Liu Yun'er wanted to do, but sitting in the front and sitting in the back were almost the same, silently opened the car door, and came directly to the back row.

Then

Liu Yun'er started the car again, in fact, it was less than five hundred roads, and in a blink of an eye arrived at the door of a research institute.

"Your girlfriend works here?" Lin Fan asked.

"Hmm...," Liu Yun'er nodded.

Words fall,

took out his mobile phone and made a call to Song Yuxi.

In less than ten minutes,

Lin Fan saw a young woman walk out of the gate.

"Xiao Yun'er, have you been waiting for a long time?" Song Yuxi opened the car door with a smile, and then sat in the passenger seat, and in an instant... Song Yuxi was stunned for a moment, but her expression recovered quickly, turned her head to look at Lin Fan who was sitting in the back row, and said, "Hello... My name is Song Yuxi. ”

"Hello, Lin Fan. Lin Fan said listlessly, and then tilted his head to look at the scenery.

Song Yuxi nodded, and then said to Liu Yun'er: "Let's go." ”

Liu Yun'er originally wanted to introduce the two parties, but the two had already introduced each other, and the process was simple and clear, she was very satisfied at the moment, and said with a smile: "Let's eat first... Find a place after eating and you can have a good chat. ”

"Hmm..."

afterwards

Liu Yun'er and Song Yuxi chatted about some trivial things in life, while Lin Fan sat there alone playing with his mobile phone.

When he arrived at a commercial plaza, Lin Fan jumped out of the car, only to see two women holding hands and striding forward, helpless to follow.

"Huh?"

"Your friend... Feel... Don't have any energy?" Song Yuxi asked cautiously.

"Oh... He's busy. Liu Yun'er said.

"Really?"

"How do I feel... He exuded a kind of..."Song Yuxi frowned and said softly: "Very lazy temperament." ”

Words fall,

After hesitating for a moment, he said cautiously: "Xiao Yun'er... It's not that I'm judged by my appearance, it's just... Your friend seems to seem... It's not like someone who understands physics, I say so... Don't be angry. ”

Liu Yun'er nodded and said indifferently: "I won't be angry." ”

Honestly,

Liu Yun'er saw Lin Fan for the first time, and she didn't believe that this guy understood physics.

afterwards

The three of them arrived at a relatively high-end restaurant, and after ordering some dishes casually, Lin Fan took out his mobile phone, anyway, he is just an outsider now, and he dares to do whatever he likes.

Then

Song Yuxi glanced at Lin Fan, who was playing with his mobile phone and playing Hache, and couldn't help frowning.

"Lin Fan?"

"Have you read the project report I wrote yesterday?" asked Song Yuxi.

"Hmm..."

"Not bad. Lin Fan said weakly.

"Really?"

"Yun'er said that you have a lot of questions. Song Yuxi said: "What are the specific problems?"

Lin Fan said casually: "It's too much... It's a bit hard to say. ”

“...”

As a researcher working in the field of relativity, being so belittled by others... No matter how good Song Yuxi's temper is, it will explode... At this moment, she was so angry that she was going to die, but because this was Liu Yun'er's friend, she didn't have the first seizure.

Liu Yun'er listened to it so much that her scalp exploded, making you not talk about it, and as a result, you chatted with people like this... Hurriedly stretched out his foot under the table and kicked Lin Fan's calf as a warning.

Sensing that someone was kicking him, Lin Fan raised his head and saw Liu Yun'er on the opposite side glaring at him, and hurriedly said, "Actually... In fact, these problems are just minor problems. ”

"Hmm..."

Song Yuxi was sad and refused to accept Lin Fan's explanation.

Time

An awkward atmosphere permeated the three of them.

fortunately

The dishes ordered were all seated, avoiding the embarrassment and continuing to spread.

In the process of eating, Liu Yuner obviously felt that her best friend had a sense of rejection towards Lin Fan, and she was also... It's hard not to be angry when you come up and be so damaged.

What's the situation?

Isn't this guy a scumbag? Why can't he be a scumbag today...

subsequently

After the three of them finished dinner, they went to the nearby Starbucks, found a relatively remote location, and each ordered a cup of coffee, at which time Liu Yun'er took out a document and handed it to Song Yuxi.

"Rain Creek..."

"Just ask if you have any questions, and he can help you solve them all. Liu Yun'er said.

"Hmm..."

Song Yuxi raised his head, looked at the listless man in front of him, and at the same time exuded a lazy temperament, and asked seriously: "You said that there are many problems in my research topic, which one is the most serious?"

"Uh..."

"Not which. ”

"Which ones should be. Lin Fan put down his phone and said indifferently.

Hearing Lin Fan's words, Liu Yun'er was about to close herself, can't she save some face for others?

Sure enough,

Song Yuxi was so angry that he gritted his teeth and asked, "Excuse me... Which ones?"

"Give me the papers. Lin Fan said.

"Give!"

Song Yuxi handed the document in front of him to Lin Fan.

Followed by

Lin Fan said to Liu Yun'er: "Pen!"

“...”

"Give. Liu Yun'er handed Lin Fan a pen.

Then

Lin Fan took a sip of the American coffee he ordered, instantly felt a little refreshed, opened the file unhurriedly, and said: "First of all, there has been a huge mistake in the holographic duality principle of gravity. ”

"A very important conclusion in gravitational holographic duality is that the entangled entropy of a subregion on the boundary in asymptotic anti-Dessitt spacetime is given by the Ryu-Takayanagi formula. Lin Fan had maintained a listless appearance, and his tone was still so lazy: "But you didn't fully understand this conclusion." ”

"That's the first point. ”

After Lin Fan finished speaking, he couldn't help but hit a hatchet, and continued: "The second point... According to gravitational holographic duality, a quantum gravitational system and a quantum field theory are equivalent under certain conditions, and for the latter, it can be written as a quantum many-body model in a lattice system. ”

"You didn't take that into account. Lin Fan didn't look at Song Yuxi's expression, and continued to speak: "Then there is the aspect of quantum information theory, when answering the question about the incompatibility between general relativity and quantum mechanics, you use the gravitational holographic duality principle to answer, which is problematic. ”

"The gravitational holographic duality does not directly answer how the information that falls into the black hole escapes the black hole. Lin Fan said: "So you can't cite this theory, but I can give you a theoretical model, which is roughly like this... If quantum information is rapidly being transported inside a black hole..."

At this point,

Song Yuxi was stunned... As a professional in the field of relativity, she almost couldn't understand what Lin Fan was talking about.

meanwhile

The other woman present seemed very excited.
