Han Le almost can't remember when the last time he had a more formal birthday, because his birthday is always next to the New Year, so every time his family congratulates him with the joy of the New Year, and when he goes to college, it is even more sad, because his birthday happens to be Valentine's Day, even if Han Le eats out alone, he will be thought that he is taking care of himself by the pair of mandarin ducks on the side.

This year, because of Qiao Yiyu's existence, the situation is much better, no matter how much I say that I am now a nominal girlfriend, although this girlfriend can only be watched from a distance and cannot be ...... But something is better than nothing.

In the afternoon, when Han Le went to the cake shop to order a cake, the cake chef asked him what he wanted to write on the cake, and Han Le thought for a while: "Just write to wish me a happy birthday, yes, I wish it." ”

At about four o'clock in the afternoon, Xie Yongqing came back, stuffed Han Le with a boss gift box, and solemnly warned Han Le: "Don't contact me at night, don't play pranks!" Then he glanced at the cake box on the table that had not been opened, and said, "Keep me a piece of cake!" Then he left in a hurry.

Han Leke didn't have the habit of leaving surprises for himself, Xie Yongqing just went out on the front foot, he opened the gift box with his back hand, and found that it was a set of dominoes, and there was a small card on the top, which read: "If you are bored, you can play at home." Han Le laughed when he saw it.

However, it is undeniable that Han Le still likes this gift - as long as it involves playing, he is interested, and it just so happens that there is no one at home now, so Han Le simply moved the table in the living room to the side first, planning to try it.

Qiao Yiyu didn't come back until half past four, it didn't seem so easy for her to pick a gift, but it was finally done, and when she got home, she was surprised to find that Han Le was lying on the ground, placing dominoes very carefully and seriously, and the huge living room had been occupied by neat dominoes.

Qiao Yiyu naturally has the concept of dominoes, but she has never seen this kind of "primitive" gameplay, so she paid attention to Han Le's progress - in fact, it was almost there, but after all, Han Le had just played, for fear that there would be an accident in the middle, so she carefully checked it before starting, and after making sure that there was no problem, she gently tossed the first domino - and then the gravitational potential energy accumulated by dominoes was naturally conveyed.

It took Han Le more than an hour to put it up, and it was finished in more than ten seconds, maybe it was the lucky aura effect of the birthday, the whole process was very smooth, and it was almost dinner time after the dominoes were put away, and the sky outside was a little dark, but it was not enough - Han Le went to pull up the curtains, turn off the lights, and create an atmosphere for himself.

"Beauty, some music." Han Le imitated the kiss of the guest at 11 o'clock and said to Qiao Yiyu, so the tune of wishing you a happy birthday soon got up, Han Le opened the cake in the dark, and then found that there was still a candle, and it would be a waste of atmosphere to turn on the light again, so he squinted and relied on the dim light of the lighter to insert, Qiao Yiyu wanted to come over to help, but Han Le said that now spirit is more important than material - how can music be broken.

After the first few candles were lit, it was simple, Han Le wanted to insert 27 candles at first, but it was too tiring - he simply used a dozen of them to put a number of 27 to be lazy, and then looked at this pile of small flames and made a wish, but in fact, he didn't make a wish, just put on a wish, as a ceremony.

After blowing out the candle in one breath, Qiao Yiyu sent the gift according to the procedure - it was the first time that Han Le had received a birthday gift so officially when he was so old, I have to say, I was still a little excited, of course, if it was sent by Qiao Yiyu, it was a little more expected, I opened it in front of me and found that there was an hourglass inside, which was really affordable and appropriate as a birthday gift, Han Le also gave it to his classmates for their birthdays when he was in college, of course, this gift was slightly lower than his psychological expectations for Han Le, but Han Le's ability to accept it has always been very strong, he still applauded, saying that he had always wanted to buy an hourglass to play.

In comparison, eating cake may be one of the most boring parts of the whole ceremony, because there are not many people, Han Le bought an 8-inch cake, with not too thick cream and chocolate on it - the master originally recommended putting some fruits and the like, but Han Le rejected them all, which made the cake look a little monotonous as a whole, but it also ensured that the taste was relatively pure, after all, in Han Le's heart, the ingredients of this cake were more important.

It's impossible to just eat cake for dinner, it's so greasy to death, so Han Le also bought some roast duck paste, ready to roll it up and eat it to fill his stomach, and when he ate it, Han Le even had several disgusting suggestions for dark cuisine - eat the dough roll with cream, or sprinkle the sweet noodle sauce on the cake, Qiao Yiyu's understanding of jokes, and the ability to draw inferences on this basis are obviously stronger, she suggested that it is better to stuff the roast duck into the cake......

After eating, the mood of the two was not bad, so by the way, the red wine that was not drunk at the Chinese New Year's Eve dinner was also taken out, and the effect of alcohol also made Han Le have no usual restraints, and he even joked with Xie Yongqing and said a joke with meat: "Let's guess what posture Xie Yongqing is in now, imitate it." Then he sat upright, and then said, "Guess what position he will be in two hours...... and he laughed to himself in the middle of the sentence, and looked like he was half lying on the sofa with an exaggerated tired face.

Under Han Le's obscene reminders many times, Qiao Yiyu finally struggled to understand this "joke", but in Qiao Yiyu's era, similar words obviously no longer have the core of a joke - because no one will feel that this kind of thing is difficult to talk about, or ashamed to say it, just like people in the 21st century say kisses without the taboo feeling of saying "kiss" in the feudal era, and even blatantly put it on TV and movies!

Han Le was still a little weak about Qiao Yiyu's smile that didn't show understanding, but fortunately, he still knew that he didn't continue, Qiao Yiyu seemed to be interested in dominoes at this time, so Han Le proposed that the two of them should put a big one together and finish all the 1,000 pieces......

Until a long, long time later, Han Le will recall today's happiness countless times, 27 years old is like a watershed in his life, no matter from what point of view, everything that happened after this is the one he couldn't imagine before, and he was not mentally prepared.

……

Xie Yongqing didn't feel good when he woke up, his whole arm was numb and he couldn't stand it, the set on TV was really deadly, what woman fell asleep with the crook of a man's arm - did the screenwriter consider a man's feelings? This is going to get married, and every day is like this, and sooner or later your hands will be crippled.

But compared to the happiness he gets, Xie Yongqing feels that this price is not unbearable, while getting dressed, Xie Yongqing is thinking nonsense, looking at the faintly prominent curves in the quilt, he feels that he seems to be a little impatient - the virtue of a man, Xie Yongqing laughed at himself.

Yan Tian felt Xie Yongqing's movements, and opened his eyes in a daze: "Why don't you sleep more?" What time is it? ”

"It's early, it's only past seven o'clock," Xie Yongqing went over and gave Yan Tian a good morning kiss, "I'll go buy you breakfast." "This dormitory is far inferior to Han Le's house, if there are kitchen utensils, Xie Yongqing can also show his characteristics as a good man at home, make a loving breakfast or something.

Xie Yongqing finished eating by himself first, dragged it for a while and then brought her a share to Yan Tian, and it was more than 7:40 when she returned to the dormitory, Yan Tian just got up, was washing her face in the bathroom, and sighed when she saw the hot breakfast, and suddenly remembered that there was something I forgot to mention yesterday: "I told my family about us during the New Year." ”

"Huh?" Xie Yongqing was obviously a little unacceptable, "Then what do they say." ”

"I didn't say anything," Yan Tian said while eating the buns, "just let me take you back to see it when I have time...... I was going to take you straight over, but you suddenly went back to your hometown......"

It's not over yet...... Xie Yongqing complained in his heart, but he was still not in a hurry: "This is too fast, right...... We're just ...... Less than a month. ”

"Remember the day you sent me back?" Yan Tian stretched out his hand to pick up Xie Yongqing's ear, "At that time, I asked you if you were developing too fast, and you said that it was not fast at all, which is normal." ”

Xie Yongqing was speechless, and the man would say anything in that situation.

"Next week, I was going to submit my resume with my classmates and find a job first," Yan Tian said again, "but my parents let me take the civil service exam, what do you think I should do?" I've heard that civil servants are boring...... But it's also stable, but it's also hard to ......."

"What do you think of yourself?"

"I just can't decide to ask you." Yan Tian's voice is as good as his name, especially when he is coquettish.

"It still depends on your own liking," Xie Yongqing said, "do you think life should be a little calmer, or a little bit of ups and downs." ”

"I," Yan Tian thought, "I thought it would be best to have both, calm and exciting...... Blandness is wonderful in itself. ”

The woman's strength came up and she couldn't communicate, but Xie Yongqing still listened patiently to Yan Tian's outlook on life, and it didn't take long for Yan Tian to get to the point: "...... What I want is actually very simple, to have a home of our own, we work separately during the day, and live in a world of two people at night......"

Is it simple? It depends on the environment, if you just find a rural village, Xie Yongqing's deposit can be basically satisfied, but if it is changed to Shenhai, Xie Yongqing feels that he will not be able to do it in his life - even in the most daring future planning, he has never thought of buying a house in Shenhai and settling down, if this plan can be simply regarded as an ideal in his high school days, it has now been upgraded to a fantasy.

Because of this topic, the originally beautiful day was overshadowed like this, and on the way to the laboratory, Xie Yongqing was still entangled in himself: "Is my requirements too low, or are other people's requirements too high?" ”

The film and the random data Xiao Lin is ready, just in a yellow file paper bag, Xie Yongqing is not in much mood to watch it now, just take it and go to the subway, there is still a lot of work waiting to be completed in his room. But when I felt bored halfway, I finally lifted my spirits, opened the file bag, took out one and looked at it, and when I saw the content in the photo, the first thought was to stuff it back and change it - Xie Yongqing didn't need to look at the multiples marked under the photo, so he knew that the magnification must be too low, because the content in the photo was too neat.

But after picking up the second photo, there was something wrong with Xie Yongqing's face - this film looks exactly the same as the one just now, it can't be a duplicate, right? Xie Yongqing took out the one that was stuffed back just now, and carefully looked at the parameters of the two photos, both of which were taken at 500,000 times, and they were two different photos - this multiple is already the highest multiple of the conventional shooting in the laboratory, that is to say, the neatly arranged and slightly blurred dots in the picture are all atoms one by one, but the question arises, how can there be such neatly arranged atoms! You must know that the metal powder he sent over for testing is frustrated off, even the surface of the material that looks smooth and has been specially smoothed will be as potholed as the Gobi Desert at such a magnification, even if the seemingly perfect crystals formed under the most ideal conditions in the laboratory will look like many irregular lines at such a magnification.

These two photos are like a spark in a dynamite keg, which ignited Xie Yongqing's whole person in an instant, and he took out other photos in the file bag one after another, looking at them one after another, most of them look the same, full of neat molecular arrangements, but in some photos in the marginal areas, Xie Yongqing can see some irregular existences - those should be individual phenomena of chemical reactions between metal and air.

Compared with nothing at high magnification, a few low-magnification photos allowed Xie Yongqing to get more information - in a few conventional photos that were only thousands of times larger, Xie Yongqing could easily see that the powders were almost all regular spherical shapes, which was not surprising, but the strange thing was that the size of these powders was almost uniform, like glass marbles - generally speaking, the most likely way to peel the material off the original surface with his rough use of a file was a pile of metal particles of different sizes, Instead of most of the consistent "assembly line products" he sees now, that is, the internal structure of this material is just as uniform and terrible as the previous surface photos!

Xie Yongqing didn't know how he walked home from the subway station, and when he reacted a little, he found that he was already sitting on a stool in the room, and a bunch of electron microscope photos had been placed on the computer in front of him - all kinds of photos, including the latest new nanomaterials developed by the country in recent years, the latest achievements of foreign peers, relevant analysis papers and reports, and the pile of photos that he had been pinching and never relaxed.

The sample was still in the file bag, it was sealed in a small plastic bag, Xie Yongqing lifted the small plastic bag and put it in front of his eyes, a little bit I didn't dare to imagine that the handful of powder inside was less than the finger cover, that is, the substances that looked flawless under the photo, he had not yet finalized what this was in the end, but this was not important - in materials science, the arrangement of materials is far more important than the materials themselves.

For a moment, Xie Yongqing almost had an impulse, and immediately rushed into Qiao Yiyu's room with these photos, and asked her questions about herself in person - there must be something wrong with this box, no, there must be something wrong with Qiao Yiyu! No, it's not all, Xie Yongqing remembered the scene that Han Le had described to himself, the metal material gradually softened, and words appeared like a display screen - if these weren't Han Le's nonsense, then the problem was big!

But Xie Yongqing, like Han Le at that time, was excited in place for a long time, but he was never able to come to a suitable conclusion - this information came too suddenly, just like the primitive people saw the lightning in the sky for the first time, and the Indians saw the giant ship on the ocean for the first time, in addition to being excited, they could only use their imagination to guess wildly - and Xie Yongqing's guessing direction was obviously similar to Han Le, he felt that the box should be some kind of latest material, but as for why it appeared here, he was completely confused.

The idea of asking Qiao Yiyu was quickly dispelled by himself, because no matter what the identity of the other party was, would he answer himself (calm down and think about it, Xie Yongqing felt that the biggest possibility was some kind of new application, and she didn't know about the nano coating, maybe she didn't know it herself, Han Le's descriptions were still too nonsense), and in that case, not only did he not get an answer, but he also complained all over his body - just secretly frustrating some powder to look at this with an electron microscope is perverted enough! Not to mention that Han Le and her still seem to be in a bit of a situation now.

After thinking about it, Xie Yongqing felt that the most reliable thing was to find Han Le to talk about it, after all, with the relationship between Han Le and himself, he could more or less understand his own approach, and then he could also ask Qiao Yiyu about the origin of the box through Han Le - this also has the advantage that if Han Le also has this information (judging from his previous description, it seems that it should be), the two can also share it with each other.

Xie Yongqing naturally didn't expect that Han Le and Qiao Yiyu had already had a private offensive and defensive alliance, but even if he knew, he would try it - although it is a universal law that there is no humanity of the opposite sex, Xie Yongqing feels that any universal law has to be discounted on Han Le's head, the two have known each other for almost 10 years, and Qiao Yiyu has only been here for more than a month.

"Han Le, are you in there?" Xie Yongqing looked at the living room with a weak heart, and after making sure that Qiao Yiyu was not there, he knocked on Han Le's door.

The door opened, but Xie Yongqing was startled like a ghost - it was Qiao Yiyu who opened the door, and she was discussing with Han Le inside about using Han Le's ID card to open a bank account.

"What's wrong with you?" Qiao Yiyu was a little surprised when he saw Xie Yongqing's abnormal face, and pointed to the paper bag in his hand again, "What is this?" ”
