——————————————————————————

Fu Yuanzhuo pedaled the lady's bicycle like a tiger, and when he encountered someone in front of him who had a car, he would press the bicycle bell hard, and the crisp sound of the jingle bell overturned the silent campus, and a boy raised his middle finger to the uncivilized Fu Yuanzhuo, Fu Yuanzhuo said loudly: "I'm sorry, there's something urgent! Hurry to see Xie Minyun!" So the middle finger was replaced with a boo, and it seemed that the night was also disturbed.

Cheng Mo took his mobile phone and watched the live broadcast sent by Song Xizhe with all his attention, and when the white light thrown out by Xie Minyun became brighter and brighter, as if it was about to burn, Cheng Mo guessed that it was a "singularity".

As the majestic cosmic music played, the words "13.82 billion years" fell from the scale as Cheng Mo expected, although the effect on the video was not shocking, but Cheng Mo could guess from the exclamation sound on his mobile phone that the visual experience of the scene must be very explosive.

Cheng Mo has a very strong spatial thinking ability, and can roughly conjure up the scene of the luminous words falling on the huge scale from small to large in his mind, and Cheng Mo began to look forward to what Xie Minyun would use this powerful light and shadow to express next.

He thought that there should not be many people present who could understand Xie Minyun, the original concept of this scale should be derived from the cosmic calendar, the day the universe was born 13.82 billion years ago, in the cosmic calendar, it is the first day of January, under this ratio, every month is equivalent to 1 billion years, and every day is equivalent to 40 million years.....

Cheng Mo grabbed the back frame of the bicycle in one hand, held the mobile phone in the other, staring intently at the screen, not affected by the speeding bicycle at all, he saw that with the continuous rotation of the scale, huge galaxy clusters, dazzling supernovas, mysterious black holes, and vast nebulae...... Like an incredible illusion, the universe is constantly expanding outward, and billions of trillions of planets have been formed in its body, and by virtue of their immediate position in the wandering journey, they constitute a constellation that can be observed by humans......

A variety of beautiful galaxies appeared in his pupils, such as the large Magellanic Nebula in the modernist abstract painting, which was so brilliant that people couldn't close their eyes, the twin galaxies composed of two overlapping spirals, their light illuminated the vast dust belt around them, like a lamp conjuring up two ghosts, and there were beautiful straw hat galaxies like Mexican straw hats, with a bulging bright nucleus in the center of the galaxy, and cosmic dust radiating around the nucleus like the brim of a straw hat, resembling a Mexican straw hat. There are fascinating large spiral galaxies, and its beauty lies in the tens of thousands of blue stars scattered around. Vast expanses of interstellar gas seem to dance the blue into swirls. And those dark matter that we don't know about escape in the extension of this vortex.

Among them is also the WeChat avatar that Cheng Mo once used, the Black-Eye Galaxy, which surrounds a dim cloud-like dust band outside the bright core, which looks like the eye of the universe......

Every time a magnificent galaxy appears, there will be a student from the Department of Astronomy or a student who loves astronomy shouting its name in the mobile phone, and then it caused an exclamation, Cheng Mo has been deeply attracted by this magnificent beauty, although he has seen a lot of documentaries on the origin of the universe, and the picture in front of him is not exquisite, he recalled that he was alone in the giant screen IMAX cinema for the second time "Interstellar" , when he saw the picture of the black hole, his eyes moistened, and the emotion in Cheng Mo's heart was infinitely magnified in this second, and he felt that if he knew Xie Minyun back then, he would definitely invite her to watch "Interstellar" with him a few more times.

But now it seems that there is no need, if he has her, he can have the magnificence of the whole universe.

The picture reaches the birth of the solar system 100-15 billion years ago, and the sun was born on August 31 in the cosmic calendar, and then when the scale turns to 4.6 billion years, in the gas and dust orbiting the sun, the solar system was born, and the earth was also born in the disk.

Cheng Mo began to understand the concept that Xie Minyun wanted to express, which was hidden in the theory of relativity, until the scale rotated to 3.6 billion years, when the words "the first single-celled organism was born in 3.6 billion years" appeared, Cheng Mo felt a deep and vast feeling different from the birth of the universe, that is a sense of joy, forests, dinosaurs, birds, insects, these creatures that are vital to human beings, were all born in the last week of December in the universe, and the first flower on the earth bloomed on December 28.

Each sinking of the scale represents that it is getting closer and closer to the birth of mankind, and it also represents that mankind is only a short moment in the long history of the universe.......

Cheng Mo guessed half of what Xie Minyun wanted to express, but he didn't guess the other half, he thought like most people that Xie Minyun would push the scale of human history to today September 20, 2020, but this time Cheng Mo guessed wrong.

When the scale rotating on the stage stopped on May 20, 2018, Xie Minyun left the piano and went on stage, putting away all the video footage floating in the void, and also putting away the scale, and the phrase "coincidence is just a matter of probability" appeared in the air.

Cheng Mo sat in the back seat and was stunned, he didn't even hear Fu Yuanzhuo stop the bicycle and call him to get off, his memory returned to May 20, 2018 in this second.

He and Xie Minyun met for the first time.

Cheng Mo's chest ignited a huge enthusiasm, as if there was a singularity about to explode in the position of the heart, he looked at Xie Minyun on the screen with dull eyes, as if he saw positive and negative matter meet and then annihilate, and it was like seeing a supernova explode in the dark night sky, it illuminated the entire galaxy, and even standing on the earth could look up at its magnificence, he seemed to see the collapse of a dying giant star, and he felt the most violent gamma-ray burst in the universe, which was more than the sum of the energy released by the sun in 10 billion years......

Cheng Mo stared at Xie Minyun's silent face with lost eyes, and it wasn't until he heard Xie Minyun say, "As long as anyone can answer me ten questions, I'll go on a date with him", Cheng Mo woke up in Fu Yuanzhuo's shout of "go to the door immediately".

His brain was buzzing, as if he had been hammered by something, he looked up at the gymnasium that looked like a huge pot lid, the moon emitted a faint halo in the gray haze, those great stars and strange landscapes were blocked from the light pollution of the city, some scorching evening breeze blew his hair, there were people cheering under the big screen of the gymnasium, the sound came from far and near, he couldn't help but look over, and saw a handsome guy in a white suit holding a tube of bright red roses on stage.

Xie Minyun stood on the stage like a god.

Cheng Mo desperately jumped off the bicycle that was still approaching the entrance, grabbed his mobile phone and ran frantically towards the entrance in Fu Yuanzhuo's exclamation, like a meteor crashing into the atmosphere.

He remembered the poem he wrote to Xie Minyun, which actually had the same meaning as Xie Minyun's show, except that his poem was much less than Xie Minyun's AR Universe - A Brief History of Mankind.

He felt the blazing air pour into his chest, his heart, his blood vessels, his muscles, his nerves...... All burn on the run.

He heard Xie Minyun's voice, which seemed to be a long radio wave through the vast time and space, and in this second, it reached an injection lock with his radio wave.

"Every atom in our bodies can be traced back to the Big Bang, so we are all children of the universe, stardust that has gained life, it took us a long 13.82 billion years to come to Earth from the singularity, and the evolutionary history of humanity began in the last hour of the last day of the cosmic year.

At 11:59:46 a.m. in the cosmic year, the history of mankind is only 14 seconds in the cosmic year, and every famous person we know only lives in this short 14 seconds.

Kings and wars, migrations and inventions, wars and loves, everything recorded in the history books, all happened in these fourteen seconds.

For Xie Minyun, the last second of the end was his encounter with Xie Minyun.

That's Xie Minyun's universe.

—————————————————————————

When Qi Shilong, who was wearing a white suit and holding a Christian Dior silver cylinder and roses, came to the stage, the entire gymnasium erupted in huge cheers, and Du Leng, who was standing on the side of the stage, frowned, because Xie Minyun's actions were really unexpected.

Yu Junshan, who was on the side, also looked at Xie Minyun on the stage and said suspiciously: "No, right? This is really not what Xie Minyun will do!"

Xu Jiyun, who was standing beside Du Leng, said: "I think it is quite in line with Xie Minyun's style, and after listening to her question, no one will dare to chase her in the future." ”

Some of the staff of the Tsinghua Student Union around said nonchalantly: "No matter what Xie Minyun is for, this is giving Brother Leng a chance!"

"Yes, Brother Leng must not give up the opportunity to date Xie Minyun to anyone else!"

Du Leng looked at Qi Shilong on the stage a little entangled, he thought that this opportunity was not necessarily for him, maybe it was for another person, but Xie Minyun didn't need to do this!

"Brother Leng, do you want to go up later? Don't give this Qi Shilong the limelight. A staff member said.

Just when Du Leng was thinking about it, Qi Shilong, who was standing on the stage, presented flowers to Xie Minyun, but Xie Minyun said coldly: "I will accept it when you answer my ten questions correctly." ”

Qi Shilong smiled and said, "Okay, I hope Xie Minyun's question is not too difficult." ”

"It's going to be hard, if you're scared, it's too late to go down now. Xie Minyun said expressionlessly.

Qi Shilong hugged the silver cylinder and shrugged his shoulders, "Since they have already come up, they are not afraid of being ugly." ”

Xie Minyun nodded, and the first question came up, "Find all the prime pairs (p, q) so that pq丨5p+5q, you have three minutes to ......"

This question is actually not difficult, but it requires a lot of calculations, but at this moment, Qi Shilong has no pen and paper to say, there are only three minutes to go, this is not a question at all, it is making things difficult, the Tsinghua students in the gymnasium are following and thinking hard, and they seem to be able to empathize with Qi Shilong who is sweating like rain on the field.

And Qi Shilong's mind was almost blank under the spotlight, he didn't expect Xie Minyun to come up with such an unreasonable question as soon as he came up, seeing that time passed minute by minute, he could only wipe the sweat on his forehead and said with a wry smile: "Give me some time to solve this problem, but three minutes is too little." ”

"I think that's enough. Xie Minyun said lightly.

Qi Shilong pretended to be chic and said: "Okay! I hope you just give me such a difficult question because you don't like me as a person, otherwise the people behind will probably not dare to come up, because whoever comes up will have the same result." ”

"There will always be a different outcome. ”

Qi Shilong shrugged his shoulders, hugged his limited silver cylinder and flowers and got off the stage, the entire gymnasium was a huge sigh, everyone didn't expect that the male god Qi Shilong of the Institute of Economics and Management actually got off the stage without answering the first question, and the people of the Institute of Economics and Management still gave Qi Shilong applause, and they all felt unfair for Qi Shilong, and felt that Xie Minyun's topic was aimed at Qi Shilong.

Even the Tsinghua leaders in the audience felt that Xie Minyun's topic was a little embarrassing, and said to the leaders of the troops on the side with a smile: "The girl of the Xie family, is this a competition to recruit relatives?"

The leader of the army looked at Xie Minyun on the stage and said with a smile: "If it is a competition to recruit relatives, ten is not enough, even if it is a thousand or ten thousand, there are many people rushing to answer." ”

At this time, Du Leng, who was standing at the bottom of the stage, suddenly walked on the stage, and he said loudly and coincidentally: "I have calculated the answer to this question, so I will continue to answer it!"

Xie Minyun turned his head to look at Du Leng, who was walking from the right side of the stage to the center, and Du Leng didn't wait for Xie Minyun to agree, so he spoke: "(2,3),(3,2)(2,5),(5,2),(5,5),(5,5),(5,313) and (313,5). ”

Xie Minyun nodded, and said without too much emotion: "Then even if you pass this question!"

The phalanx of the Faculty of Science erupted in loud applause, while there were boos from the School of Economics and Management, believing that Xie Minyun was releasing water, as if this had become a struggle between the two faculties.

Du Leng breathed a sigh of relief, although he knew that he might not be able to stand at the end, but he still didn't want to give up this once-in-a-lifetime opportunity, Xie Minyun was a girl he couldn't and didn't want to give up. And after entering Taijilong, he also has a certain confidence in his mathematics, physics and chemistry level, like just now, he can still cope with a problem that only requires computing power, as long as he does not step down too early, Du Leng feels that it is a big victory.

Du Leng, who was already ready, watched Xie Minyun with bated breath and waited for her to come up with the second question, while the students in the gymnasium also quieted down, waiting for Xie Minyun to come up with the question.

Xie Minyun, who was standing in the spotlight, didn't look at Du Leng at all, but looked at the entrance of the infield, and said lightly: "How many masterpieces of Leonardo da Vinci are there, and where are they?"

Originally, Du Leng thought that the second question would also be the first Olympic-type mathematics, physics and chemistry question, but he didn't expect Xie Minyun to make such a big turn and ask an unbelievable art question, Du Leng usually never pays attention to the useless things of art, and even if he does, he doesn't think that there will be many famous paintings that have attracted worldwide attention.

He asked with a dull expression, "Is this a brain teaser?"

Xie Minyun shook his head, "It's a normal art problem." ”

At this time, someone in the audience whispered: "3, 3, 3......"

Du Leng pretended not to hear, and said as if he was thinking: "It should be 3.... As for the place....."

Du Leng was about to continue to listen to the people in the audience give him an answer, but he heard Xie Minyun interrupt him, and said lightly: "Wrong, not three." ”

Du Leng smiled bitterly and asked in a low voice, "Are you waiting for him?"

Xie Minyun didn't answer, still looking at the door at the entrance of the gymnasium.

Du Leng followed Xie Minyun's gaze and looked over, then turned around and walked towards the stage with a lonely face, seeing that Du Leng stepped down from the stage with the second question, a huge cheer broke out in the direction of the School of Economics and Management, and there was silence on the side of the School of Science.

The audience who was watching Baidu with their mobile phones was in an uproar, but they didn't expect that the vice president of the student union, Du Leng, the male god of the School of Science, actually answered the second question incorrectly, and the audience on the stage began to discuss, some of them didn't understand what Xie Minyun was going to do.

A supporter of Du Leng's girl said dissatisfiedly: "Xie Minyun doesn't play like this in order to be in the limelight, right?"

"Isn't that a pastime? The Mona Lisa's Smile is known to have only one piece!"

"Maybe the answer is a picture, and that's what she asked on purpose?"

Some people even shouted: "No one can answer such a question!"

Xie Minyun turned his head and looked in the direction of the voice, took the microphone and whispered: "Someone must be able to answer ten questions correctly, who wants to come up and try?"

The person who spoke just now saw Xie Minyun looking over, shrunk his head, and showed a silent expression, seeing Xie Minyun's somewhat cold face, the entire gymnasium seemed to have been hit by a cold snap, and was instantly frozen and fell into silence.

At this moment, the brown fire door at the entrance of the infield of the comprehensive gymnasium was gently pushed open, and Cheng Mo, who was sweating profusely, walked in from the entrance, he stood at the entrance and raised his hand, and said loudly: "I want to answer the question....."

At this moment, Cheng Mo seemed to find the feeling when he raised his hand on the K20 train to ask for a game for the clown, he raised his right hand high, and the other hand held the mobile phone that was still broadcasting the live scene, he watched Xie Minyun's quiet face slowly walk towards the stage along the passage of the infield.

At this time, the whole gymnasium looked at Cheng Mo who was walking towards the stage, and their eyes shot at him like sharp arrows, Cheng Mo's memories entered that absurd, bloody and incredible journey, he took the hand of the girl in front of him who seemed to be impossible to touch in the narrow train corridor, the white curtains were blowing by the broken window, and the blue Lake Baikal on the other side was as smooth as a mirror.

He remembered the lyrics of "Lake Baikal" that he had just heard, "How many you and I are in this life."

Swallowed up in the moonlit night

I want to think about the past again one day

We lingered on the shores of Lake Baikal

How many years later, the past will go with the clouds

The flying ice and snow can't accommodate the gentleness

This life is too little time

Not enough to prove the affection of melting snow and ice"

In the process of running just now, he finally realized the "impulse" that Fu Yuanzhuo said, the strong urge to run away no matter where the girl he liked was.

Cheng Mo, who looked a little embarrassed, walked in front of everyone, his white T-shirt was covered with sweat, his hair that had been cleaned was blown into a chicken nest, there were no flowers in his hands, only a mobile phone that was still glowing, and the black glasses on the bridge of his nose seemed to be slanted a little, he reached out and pushed it......

Song Xizhe, who was above the stage, stood up and shouted, "Come on, Cheng Mo!"

Cheng Mo, who walked to the red carpet in the infield, glanced back at Song Xizhe, who was waving, and he hooked the corners of his mouth and smiled, this smile made him look a little embarrassed.

The noise in the gymnasium was ignited by Song Xizhe's shout, and people asked who Cheng Mo was.

Especially in the direction of the Faculty of Science, all the freshmen were surprised, and everyone still had some impressions of Cheng Mo, who only came to the stage to accept the award in the afternoon.

"Isn't this Cheng Mo?" someone said loudly,

"Cheng Mo, isn't that literary otaku from our astronomy department?"

"Literary otaku? You mean the man with glasses who reads the original English book every day?"

"That's right! Just call him Cheng Mo, as his name suggests!"

"My God, I didn't expect him to dare to go up and answer Senior Sister Xie Minyun's question. ”

"I don't think he can answer a single question!"

"I also think that the first two questions are so difficult....."

"Why go up and be embarrassed? I guess I'm a fan of Xie Minyun like Xiaopang! Maybe he also studied astronomy for Xie Minyun!"

Ye Lushan, who was sitting in the stands, didn't speak, she looked at Cheng Mo's small back in the audience and remembered the neat stack of notes, she had a premonition that she seemed to have missed something.

Xu Jiyun, who was standing on the side of the stage, was a little surprised, obviously she had recognized the ordinary boy she had seen during this summer vacation, and some people said at that time that he was Xie Minyun's boyfriend, Xu Jiyun said with an incredulous face: "Xie Minyun..... You can't be waiting for him, are you?"

Du Leng, who was standing on the side, did not speak, but Xu Jiyun saw that Du Leng, who had always been calm and was in danger of anything, was trembling, and Yu Junshan's face on the other side turned blue, Xu Jiyun immediately realized that the situation was wrong and was not talking.

After a while, Xu Jiyun heard Yu Junshan say with a weak heart: "Maybe Cheng Mo will be ousted from power soon, Xie Minyun will not like a poor boy who has nothing! Her family will not agree to ......."

Du Leng closed his mouth tightly, he had already seen Xie Minyun's cold eyes revealing a tenderness that he had never seen before, and he also felt that the ice and snow melted in the distant mountains, and the golden spotlight was the sun, no, maybe Cheng Mo, who was gradually approaching, was Xie Minyun's sun, making her coldness and nobility turn into gentleness.........
