(Thanks to the "Xiao Xiao Great Demon King", "The Dream of the Other Side", and "Love/Nine Foxes" for the ten thousand rewards, I stayed up all night to drive this chapter out, ask for a monthly pass, and I wish you all a happy New Year!)

Cheng Mo walked on the scene of the grandest welcome party in the history of Tsinghua University, stepping on the thin red carpet, he thought to himself that the quality of this red carpet is worrying, there is no softness of the Persian carpet at all, probably the school wholesaled from the splendid land that specializes in selling wholesale carpets, fortunately there are no flower balls next to the red carpet, otherwise it feels like a wedding scene.

He looked at Xie Minyun on the stage as he walked, he hadn't seen her for two years, she was more goddess, more unattainable, her clear and crisp face exuded nobility and arrogance, compared with her, the light emitted by the millions of spotlights hanging on the stage was not worth mentioning, where she was, everything was a foil, such a beautiful Xie Minyun made Cheng Mo feel flustered.

However, when he saw that Xie Minyun was still wearing the skirt they wore when they were separated in Yuelu Mountain, Cheng Mo felt a little more relieved, he felt that Xie Minyun seemed to tell him in this way that she was still the same person and had not changed.

Even so, Cheng Mo's heart was still a little apprehensive, he experienced the great power of love for the first time, and it seemed that the two years of separation had not been able to extinguish the fire in his heart, and in the long-term depression, when it was suddenly released, the fire burst out with incredible energy.

The light was getting closer and closer, Xie Minyun was getting closer and closer, and Cheng Mo felt hot all over, as if he was like a match, which could burn at any time.

Cheng Mo looked at Xie Minyun in the spotlight, she was so dazzling, so dazzling that Cheng Mo didn't dare to look at it directly, Cheng Mo guessed that it was also because the white one-shoulder dress worn by Xie Minyun was like a wedding dress.

Cheng Mo finally walked through the middle of the infield, and when he passed his 9 rows and 9 seats, a voice stopped him, "Hey, since you are going on stage, why don't you bring a bouquet of flowers." ”

Cheng Mo turned his head to look at Qi Shilong, who was sitting in 9 rows and 8 seats, he had just seen him on the big screen outside the gymnasium, a handsome man dressed in white, Prince Charming, but unfortunately Xie Minyun was not a princess, she was a queen from outer space. Cheng Mo moved his gaze to the silver diamond barrel placed on his stool, he hesitated for a moment and asked, "What, you don't want this flower?"

Qi Shilong didn't laugh like Prince Charming at all, like a gray wolf carrying a frying pan, "Yes, so..... If you are willing to take this bouquet of flowers and give it to Xie Minyun, I think she will be happy. ”

Cheng Mo looked at the gorgeous flowers that seemed to be watered by blood, and there were several crystal clear droplets on the delicate petals, he remembered NGC2237 (Rose Nebula), if he wanted to send Xie Minyun flowers, he would definitely use rubies and diamonds to inlay a picture of a NGC2237, Cheng Mo regretted that he couldn't do it now, but he decided to take the first step in his life, he asked Qi Shilong with a dry throat: "I only need one, is it okay?"

Qi Shilong took out the largest one from the silver cylinder and handed it to Cheng Mo, and said with a smile: "Of course you can." His smile is extraordinarily sincere, sincere like a charlatan, who can't help but smile when he has cheated customers out of their money.

Cheng Mo took the rose from Qi Shilong's hand and said in a low voice: "I didn't take your flowers for nothing, this is the fee charged for you to use my seat." ”

Qi Shilong's expression was a little stunned for an instant, and he asked with some surprise: "9 rows and 9 seats...... This...... This is your seat?"

Cheng Mo nodded, took out the crumpled ticket stub from his trouser pocket and handed it to Qi Shilong, and then said, "Thank you." ”

Qi Shilong took the ticket stub a little dazedly, and looked at the seat number on it, it was indeed 9 rows of 9 seats in the infield, he was a little curious about why Cheng Mo didn't come, and he was just about to ask, but he saw that Cheng Mo had already walked a few steps, and he didn't know if the gaffer was too boring, so he chased the light for the little boy in front of him, holding a rose in his hand with a sweaty face on his face, and walked in the pillar of light focused by thousands of pairs of eyes.

"Dare to appear like this? It's too unkempt! If I were Xie Minyun, I guess I wouldn't even give him a chance to ask him questions!"

"Qi Shilong and Du Leng are still like that, what the hell is this freshman?"

"I don't know if Xie Minyun's charm is too great, or if this freshman is too bold!"

"I bet he won't be able to answer a single question!" Xie Minyun will probably give him a super difficult question......"

All kinds of questions flowed in the crowd, and some even joked that they would go on stage to answer Xie Minyun's questions when Cheng Mo stepped down, even if he couldn't answer it, it would not be a shame, and he could get close to the goddess in his heart.

Except for a very few people, no one is optimistic about this somewhat ordinary-looking teenager, everyone is waiting to see his jokes, although even if it is a joke, his jokes are far less worthy of mentioning than the first two, but more or less when mentioning this big scene that made the whole school sensational, Cheng Mo's name can be simplified into a number, and the first two are tied, which is not a success.

Cheng Mo turned a deaf ear to these, in fact, these melon-eating masses did not exist for him, he only had Xie Minyun dressed like a bride in his eyes, he walked along the edge of the stage past Du Leng who finally couldn't keep smiling, he didn't look at Du Leng, he didn't even notice Yu Junshan standing in the shadows, these people didn't matter, and in this second, only Xie Minyun was left in his universe.

He walked on the stage, and suddenly felt that Tsinghua's comprehensive gymnasium was quite large, even if it was full of people, it still looked empty under the dome, and he walked towards Xie Minyun in the middle under the scorching spotlights, the stage was covered with a layer of dark purple flannel, and there were several circles of spotlights solidified on it, like floating bubbles.

Cheng Mo walked in front of Xie Minyun with a rose in his hand, and this section was two years away from him.

Xie Minyun, who was originally facing the stands, turned around for the first time, and when she asked Qi Shilong and Du Leng questions just now, her body didn't shake a little, but at this moment she turned around and faced Cheng Mo who walked from the side of the stage.

The two men silently looked at each other in the center of the stage, and the entire gymnasium fell silent, and everyone opened their mouths wide to see what seemed like an incredible scene.

Even a single turn was enough to surprise them.

A few seconds later, the two of them opened their mouths at the same time, closed their mouths at the same time, and after a few seconds again, Xie Minyun chuckled, like a glacier melting and everything recovers. Cheng Mo picked at his somewhat itchy scalp that was illuminated by the spotlight, and said softly: "Senior sister, you speak first." ”

Xie Minyun glanced at the roses in Cheng Mo's hand, snorted coldly and said, "I don't have anything to say to the person who plans to give me the roses that others bought!"

Xie Minyun's cold tone made Cheng Mo's always expressionless face appear nervous, he also knew that this was not appropriate, but he didn't want to go on stage empty-handed, he let out a long "ah" in embarrassment, pushed the glasses on the bridge of his nose, and whispered in his heart: "Or, I'll return the flowers?"

Xie Minyun said angrily: "What time is there to delay? Answer the question first, if you can't answer the question, you will have more time to pay it back!"

Cheng Mo lowered his head and wiped the beads of sweat on his forehead, he was a little afraid to look at Xie Minyun's expression, afraid that what he saw was that Xie Minyun was really angry, thinking about it, she did have enough reasons to be angry, Cheng Mo hurriedly said: "Ask!"

The moment Cheng Mo lowered his head, he missed Xie Minyun raised his hand to help her wipe her sweat, but unfortunately the moment he looked up, Xie Minyun remembered something again, so he immediately took his hand back, and it became the action of taking the microphone from the microphone stand, she held the microphone and said: "A finite complete diagram Kn, n is an even number, you and I take turns to choose the side from Kn, I take the first hand until all the points are even, the game stops, the last person to operate wins, for the given n, am I or do you have a winning strategy?" ”

Seeing that Xie Minyun pointed the microphone at him, Cheng Mo replied without hesitation: "Of course it's you." ”

Xie Minyun looked at Cheng Mo and asked, "Did you know the result without even calculating?"

Cheng Mo replied as a matter of course: "Understanding the examiner is also what candidates should do, not to mention that this question is really not difficult to calculate." ”

Xie Minyun nodded, "Then you have to be careful next." ”

There was an uproar in the stands, they didn't even understand the question, and this question was over?

Xie Minyun ignored the noise in the stands and continued to ask: "Where are the differences between the several paintings of "Mona Lisa's Smile"?"

Xie Minyun asked Du Leng about this question at the beginning, and everyone was also very curious about the answer to this question, so the hustle and bustle stopped abruptly, and everyone looked at Cheng Mo in the center of the stage to see if he could answer.

This question couldn't be simpler for Cheng Mo, when the two of them visited the Louvre together, they had discussed Leonardo da Vinci and his peerless painting, so Cheng Mo said into the microphone: "Mona Lisa is a portrait painted by Leonardo da Vinci to the wife of his father's tenant, legend has it that Leonardo da Vinci painted two portraits of Mona Lisa, one of the evidences is that Saint Raphael once copied the "Mona Lisa's Smile", and this copy of Saint Raphael has eyebrows, so there is no doubt that Leonardo da Vinci painted two " The Smile of the Mona Lisa" has one with eyebrows and one without eyebrows, and as for the original painting with eyebrows, it is hidden under the one without eyebrows, so both paintings are hidden in the Louvre......"

Xie Minyun nodded, "Correct." ”

The audience was silent, none of them knew whether what Cheng Mo said was true or false, they looked at each other and didn't know what to say, and some people were using the role of search engines, but they couldn't find the answer.

Xie Minyun looked at Cheng Mo's trouser pocket and asked, "You just watched the live video, right?"

Cheng Mo nodded.

"What is wrong with the expression of black holes in the popular science AR video just played?"

At this time, everyone's eyes turned to the direction of the Department of Astronomy, but the freshmen of the Department of Astronomy looked sluggish, fully showing that I was in a state of confusion.

Cheng Mo closed his eyes and recalled, and said: "There is no redshift effect, you can imagine a spherical light source moving towards you, due to the absolutist Doppler effect, the frequency of photons flying towards you decreases, that is, it turns blue. At the same time, you will receive more photons per unit of effort, which is similar to the normal Doppler effect, you can equate each photon to a crest, so the light source will become brighter. Conversely, when viewed away from the light source, the light source becomes dark and red. If the speed of the light source is quite close to the speed of light, a large part of the energy will be concentrated and radiated to the back of the light source, like a very narrow beam, so it is called the absolute beam gathering effect..... Perhaps in order to make black holes appear more intuitive, the redshift effect, which is difficult for ordinary people to understand, has been canceled......"

Xie Minyun looked at Cheng Mo and hooked the corners of his lips, showed an appreciative expression, and said lightly: "Yes, this has been noticed, correct." ”

At this time, the principal was not calm, and turned his head to ask the professor of the astronomy department sitting behind him, and the gray-haired old professor said to himself: "I even ignored this, I didn't say it just now, I haven't been able to remember it." ”

The principal looked up at Cheng Mo and said, "This student ..... It's not easy!"

All the chatter around them couldn't interfere with the two of them, and Xie Minyun continued to ask, "How can you see the sun rising in the west in a normal way?"

Seeing that Xie Minyun asked another unbelievable question, the entire gymnasium quieted down again, and Qi Shilong, who was sitting in the infield, breathed a sigh of relief and said in his heart: "Although you answered the previous few questions correctly, but this kind of impossible thing, how to answer?" Then he was very annoyed and thought about how Xie Minyun's first question to him was so difficult, but it seemed that he couldn't answer any of the questions just now, which made Qi Shilong fall into anxiety again, praying that Cheng Mo would get off quickly, otherwise his face would be lost.

The audience on the stage is also thinking about this impossible question, some people say that they will move to Venus to live, some people say that they will fly in the opposite direction of the earth in a super fast plane, but this is not normal!

The people in the entire gymnasium thought that Cheng Mo should end there, but they had already memorized the name and correctly answered Xie Minyun's three questions, surpassing Du Leng and Qi Shilong's men......

However, they were soon disappointed, and Cheng Mou, who was standing in the spotlight, pondered for a moment and said very calmly: " Simply put, if you want to see the sun rise from the west, as long as you move in the opposite direction along the direction of the earth's rotation, when the speed of movement exceeds the speed of the earth's rotation, you can see the sun rising from the west, that is, close to 2,000 kilometers per hour, such a speed is difficult for ordinary people to achieve, but there is a way, when you go to the south pole or the north pole, the latitude of the polar region is relatively high, and the radius of rotation is relatively small, so you take a plane from Canada to Alaska in the evening, or the plane from Moscow to Helsinki, Finland, Alaska and Helsinki are high latitudes, the speed of the earth is low, the speed of the plane can easily exceed the speed of the earth, and at this time it is easy to see the sun set first and then rise in the west...."

After a moment of silence in the entire gymnasium, there was warm applause, Tsinghua is a school that respects wisdom, and Cheng Mo won the applause of all Tsinghua students with his incredible thinking ability and reaction speed.

At this time, someone remembered that Cheng Mo was the double champion of arts and sciences in Xiangnan Province, and someone immediately shouted, "Isn't this the big bull in Xiangnan Province, who took the college entrance examination in both arts and sciences at the same time, and scored 749 points at the same time?"

"It seems to be eh, how could it be him?"

"No wonder he's so good! I feel like he can answer ten questions correctly!" someone said excitedly.

"The previous questions are already so difficult, and the later ones should be even more difficult. ”

"I'm really looking forward to the next question, I feel like I've learned a lot!"

Xie Minyun and Cheng Mo's tense and exciting Q&A continued, the audience at the scene seemed to have seen an exciting Q&A show, and it seemed to be at the scene of the strongest brain, Xie Minyun's questions were either tricky and weird or needed to count the mysterious ones that required powerful calculations, but Cheng Mo calmly solved Xie Minyun's problems again and again, winning thunderous applause again and again.

If it wasn't Xie Minyun who asked the question, and the prize was Xie Minyun's date, everyone would definitely think that Cheng Mo was invited by Xie Minyun, seeing that Cheng Mo had reached the ninth question, the mood and breathing of all the audience at the scene were urgent, for the vast majority of people, seeing Xie Minyun fall into the world and go on a date with a boy she would never fall in love with at all can be regarded as watching a farce, at least it is much better than seeing Xie Minyun and Du Leng, or dating Qi Shilong.

After all, the possibility of Xie Minyun being with Du Leng and Qi Shilong is much more likely than being with Cheng Mo, and Cheng Mo's IQ and solid knowledge base make them have to admire, everyone feels that if Cheng Mo is not too ordinary, it is also a match for Xie Minyun, a true scholar goddess, but the two of them are too mismatched from the outside, which makes them both sorry and happy.

In any case, Xie Minyun is still Tsinghua's Xie Minyun, not someone's Xie Minyun.

However, when Xie Minyun asked the ninth question, everyone thought that Xie Minyun would increase the difficulty of asking a difficult problem that made people give up thinking, such as "NP problem", "Huo Wei conjecture" or "Riemann hypothesis", which may not be able to solve in a lifetime, but Xie Minyun asked a question that made the hearts of the boys in the audience tremble.

She stood in the spotlight with the microphone and asked, "What would you do if you were asked to confess to a girl!?"

As soon as this question was asked, no matter how dull people were, they knew what the two people on the stage had, and the sound decibel level was almost comparable to a vegetable market in an instant, you must know that this is Tsinghua University, which has always been famous for its high quality.

Cheng Mo, who was standing opposite Xie Minyun, turned a deaf ear to this huge hustle and bustle, he met Xie Minyun's clear gaze and said softly: "I will take her to see the aurora." ”

Xie Minyun was stunned for a second, and then echoed: "It's so romantic." ”

Qi Shilong, who was sitting in the audience, couldn't stand such a big stimulation anymore, and said loudly in his seat angrily: "What's so romantic about watching the aurora? Xie Minyun As long as you want, I can take you to live in the space hotel!"

Qi Shilong's clamor didn't cause any waves, because the phalanx of the Faculty of Science erupted in a deafening applause, and then someone shouted: "Cheng Mo is awesome!"

There are also people who shouted unscrupulously: "Cheng Mo, you are the last love master of our science students!"

"Cheng Mo took Xie Minyun to see the aurora!"

Many people didn't know why, and they asked, "What's wrong?"

Someone said with tears in his eyes, "Don't you know...... The aurora is green!"

"Green?"

"Love is a light, so green that you panic?"

"Originally, I thought it was quite romantic to watch the aurora, but you guys said that I don't think it's appropriate to watch the aurora confession, right?"

"Damn, so you idiots don't understand the romance of science and engineering men!"

"So, showing something green to someone you like is a confession?"

"You know the! The wavelength of green light is 520!!."

"Grass! is that okay?"

"This works....... Capitalized convincing !!!"

"He is worthy of being the last love master in science and engineering!"

"God-like confessions! learned! learned!"

"Is this how Green Light really opens?"

"The double champion of arts and sciences deserves to be the double champion of arts and sciences!

—————————————————

ON THE STAGE, OF COURSE, XIE MINYUN WAS ABLE TO GET TO CHENG MO'S CONFESSION, SHE LOWERED HER VOICE SLIGHTLY FOR THE FIRST TIME, AND HER ORIGINALLY SLIGHTLY COLD TONE SOFTENED, "THEN THE LAST QUESTION ......" PAUSED SLIGHTLY, XIE MINYUN STARED AT CHENG MO INTENTLY, AND AFTER A WHILE, SHE LIGHTLY OPENED HER LIPS AND ASKED IN A SHALLOW VOICE: "Then you won the opportunity to date me, where will you take me?"

Xie Minyun's sound wave was like a powerful vacuum bomb, instantly destroying the gymnasium like a huge bunker.

The entire Tsinghua Comprehensive Gymnasium was still amazed at Cheng Mo's brain hole a second ago, and all the sounds were swallowed up by Xie Minyun's question in this second, and the huge gymnasium fell into a death-like silence, like a lonely relic on a desolate planet in the vast universe, there was nothing here, only the bright starry sky above the head was flickering silently, and it was so empty that even the wind could not be heard, like a cursed castle.

Cheng Mo stood in the center of the stage and also looked back at Xie Minyun, he remembered that Xie Minyun led him down the steps, at this time it happened that the rain stopped, and a colorful rainbow hung in the sky, as if before that he was holding Xie Minyun's hand through the long K20, she said a lot to him, some were very warm, some were very inexplicable, Cheng Mo thought to himself that my reflection does not need you to correct it, and I will not incarnate as a demon and need you to ignite it.

But this world is worth my attention now, and so are you.

Cheng Mo stared at Xie Minyun's deep and silent pupils like a galaxy with black eyes, he felt that he would not avoid this answer, when a girl expressed her longing in this extreme romantic way, Cheng Mo felt that he couldn't and couldn't refuse, so he said in front of thousands of people: "I will take you to see the aurora." ”

Xie Minyun smiled, like a little star in the night sky.

"From the origin of the universe to the disappearance of the last black hole, life, as we know, has only a 1 in 100 billion likely. ”

"So for me, the great miracle of the universe is not stars, not planets, not galaxies. ”

"Not even material. ”

"It was a moment in a long time. ”

"That moment was now. ”

"It's been so long. ”

"Life is so short. ”

"Then Cheng Mo, what are you waiting for?"
