The whole world is waiting for us to break up

After Dong Shuoye sent this message in the group, Su Yu was stunned.

It's not because he made that bet, he and Dong Shuoye grew up together, and what they like to do the most is choke each other.

Xia Ran lived opposite Dong Shuoye when he was a child, and he was called brother since childhood. Dong Shuoye and Xia Ran are also closer than him.He doesn't care where others bet, he only cares about one issue.

He made a phone call directly: "What do you mean? What do you mean that the existing technology can't solve it? Is the case that my sister-in-law took over this time so difficult?"

Dong Shuoye said leisurely: "Why, you didn't investigate before investing, but instead asked me the reason for this opponent's bet? Do you have such an empty bet?"

Su Yu: "Fuck, I just support my sister-in-law. What's wrong, I support you unconditionally! Don't talk nonsense here, tell me quickly."

"After finishing speaking, can you give Lin Shuicheng a thorough question?" Dong Shuoye's voice was still slow.

Su Yu was poked at the center of the matter, and said cheekily and nonchalantly: "How is it possible, my sister-in-law and I haven't gotten to know each other that well yet. You said I was going to lose money and I didn't have to ask? What's going on, you and I Let’s talk. We’ll see you for a barbecue in the afternoon.”

"I think you just want to come out for dinner?" Dong Shuoye paused, as if he had checked the itinerary with the secretary beside him, and then turned around and told Su Yu, "I can't come tonight, I have to go back to have dinner with the old man, you Now I can come over to the cafeteria of the General Affairs Office if I have time, or I will tell you on the phone."

Su Yu immediately said, "I'll come here! What are you eating? It's better than eating boiled cabbage at home."

Dong Shuo smiled at night.

Su Yu's boiled cabbage is really boiled cabbage, the kind that leaves the bird in the mouth after eating.Their family is still under strict control, and they don't even allow snacks.

This was most obvious when they were in junior high school. At that time, Su Yu and Fu Luoyin transferred back to Xingda High School to live and study at the junior high school. The meals in the junior high school were notoriously unpalatable. Fu Luoyin and Dong Shuo Ye and Xia Ran go to the canteen every day to buy the instant noodles cooked by their auntie, but Su Yu alone can eat a lot of them in the cafeteria, and then wonder: "I think it's delicious?"

Su Yu immediately took a taxi and went straight to the office building of the General Affairs Office.

As soon as he entered the door, he directly poured out the top black tea that Dong Shuoye kept privately, and went to the tea room to get the milk powder package.

After making milk tea, he sat down opposite Dong Shuoye, and Shi Shiran said, "Please. What advice does Teacher Dong have?"

Dong Shuoye adjusted the laptop on the table and projected it onto the indoor slide screen.The moment the light hit, it was the summary report of the General Affairs Office on the famous painting appraisal case.

The first page of the PPT is a high-definition scan comparison of the two paintings, which is the posthumous work of a world-renowned painter.Su Yu doesn't know the specific artistic value, he only knows that if there is no way to compare the results of this painting, then the consequences must be very serious.

"First of all, this painting is an oil painting from the 75th century. It has been stolen seventeen times in such a long time. After the last time it was stolen, this painting suddenly appeared anonymously at an auction and was bought by a respected collector. Collection, and is expected to donate back to the Union Museum on her [-]th birthday. However, just before the donation, her collection was stolen for the second time. When it was recovered, a total of two paintings were recovered. After investigation by the criminal gang, there is a high probability that they are wanted by the Union They have been a high-tech crime group for five years. They have a fixed organization name: RANDOM.

"This collector is the informant this time. The request is to ignore the criminal first, but the appraisal result must come out. You don't need to know her name. The other party hopes that this investigation will be conducted in secret, and it is best before her 75th birthday. The truth came to light. Our General Affairs Office attached great importance to this case, but soon discovered a technical problem that could not be broken through."

Su Yu subconsciously asked: "How long is left?"

"It was seven days before, but now it is five days." Dong Shuoye paused, "Five days and eight hours. The two paintings have been handed over to Star City Alliance University, and Lin Shuicheng and Yu Fan have seen them two days ago."

Holding the hot milk tea in his hand, Su Yu took a sip at a loss, then said, "Go on, what's the problem?"

Dong Shuoye tapped his fingers on the desk, "For the appraisal of famous paintings, especially this kind of oil paintings from the [-]th century, conventional inspection methods are the most direct and common appraisal methods, such as studying the colors, observing the style of painting, and appraising the materials of the pigments."

"Each painter has a different personal style. For example, Salvador, he is a typical painter whose brush effect cannot be seen on the canvas, and his brush strokes are very smooth. The second is cracks. Oil paintings usually have cracks after 50 years of storage. Counterfeiters generally use oils mixed with water-based liquids to create the same crackle effect, which is the most basic style comparison.”

"The General Affairs Department invited the most authoritative historical and art appraiser from the Star University Academy of Fine Arts, but the other party said that there was nothing they could do. We then used X-ray scanning to identify the texture of the canvas. In the [-]th century, many merchants who sold canvas would put a layer of white lead on the canvas. Paint, canvas fibers are different in concave and convex, and the degree of blocking X-rays is also different, so that the irradiation can show the material of the canvas. It is very likely that the same material of the canvas by the same author at the same period is very likely. The appraisal personnel use this method to compare the author's work The success rate was relatively high during the conversation period. But unfortunately, this work is now a work of the [-]th century, and the canvas was not painted with white lead paint at that time, and X-ray inspection is invalid.”

"The radioisotope detection method failed at the same time. The counterfeiters obviously disassembled a large number of oil painting components of the same period to counterfeit. The radioisotope inspection of the two paintings shows that they are of a similar period. At the same time, the detailed completion time of this painting is missing."

……

At the same time, Lin Shuicheng was on the phone in front of the French window at home.

The lights were not turned on at home, and he had been on the phone for an hour.

The sky outside the floor-to-ceiling windows changed from bright white to yellowish yellow, and then from yellowish yellow to slightly blue. After taking a shower, he was wearing a shirt and jeans, and walked lightly on the smooth floor. His skeleton was tall and thin, and his back was straight.The chief lay at his feet, chasing after his trousers legs and scratching them with his paws.

This is what Fu Luoyin saw when he came back. The house was dark and dark, and the lights were not turned on.

The curtains of the floor-to-ceiling windows were drawn tightly, and the last rays of the setting sun were evenly applied to Lin Shuicheng's body. The long and thin shadows drawn from his back made him look lonely and cold.

Fu Luoyin just came back from get off work, Lin Shuicheng didn't hear his voice when he entered the door, but the chief looked back at him vigilantly.

His hand was on the light switch, but he still couldn't press it.

Fu Luoyin just walked in and sat down on the sofa without disturbing him.

Lin Shuicheng's voice was light and pleasant, and he spoke eloquently.His straight and round accent should be suitable for reading stories, and it should be very attractive to girls.

"X-ray irradiation to identify the canvas is not feasible, and the old identification method is not feasible. The identification personnel of the General Affairs Office took samples of the cross-sections the size of ballpoint pens, and then used a scanning electron microscope to conduct material analysis. It was found that they were all around the fifteenth century. The material of the paint, even the thickness of the paint and the coverage of the strokes are highly similar. After this step, the General Affairs Office began to use AI firmness. The researchers of the Old Netherlands Branch provided an AI algorithm that can be used to describe the outline through the complementary colors in the painting , to analyze the difference in image profile between the genuine and the counterfeit, but this step also failed, and it is currently impossible to read any color differences."

"The second AI algorithm that appeared is the brushstroke algorithm that has been used in the last century and has a success rate of over 90%. After computer scanning, it can analyze the unique strokes and lines in the work. The museums of each branch confirmed it through such a comparison. There are already thousands of authentic works, and any written material left by the painter can be used as a reference for the strokes entered by AI to digitize people's habits. But this method also failed. The result read by the algorithm is that the two paintings have The exact same strokes."

On the other hand, Yang Zhiwei deliberately spared time to call this former student.

When Lin Shuicheng talked about this, both of them had the answer in their hearts.

Yang Zhiwei said: "In this way, criminal gangs should have used molecular or even atomic-level replication methods. This is not an ordinary counterfeit production, this is a demonstration, no matter whether it is molecular stacking or atomic stacking, a A complete replica, this is a demonstration to the academic and artistic circles, and to the entire Union police. Why does a criminal group, a gang of thieves, have such advanced technology? The world's best covered atomic probes and molecular probes The needle is in my lab, so who provided their lab?"

Lin Shuicheng said: "The General Affairs Office probably hasn't thought of coming here yet, because there is no equipment certified to this level. The latest equipment in Star City can only be accurate to the nanometer level, that is, the molecular level. Teacher, I think, for the sake of insurance, can you..."

"Shui Cheng, time is too late." Yang Zhiwei said, "Scanning atomic-level analysis and comparison, sent to us for comparison, will take ten days at the fastest, and you only have five days left for your mission."

Lin Shuicheng insisted: "We don't need to scan and analyze everything, we only sample and analyze the atomic level comparison of the cross-section, is that okay?"

Yang Zhiwei said: "...Shuicheng."

His suddenly serious tone made Lin Shuicheng stunned for a moment.

When Yang Zhiwei's tone sank like this, Lin Shuicheng was very familiar with it.When he was an undergraduate student in the Jiangnan branch, every time he thought about the wrong direction, or got into a dead end, Yang Zhiwei would talk to him in this tone, asking him to go back and think again.

At this time, if he continued to follow the train of thought just now, Yang Zhiwei would just wave his hand to tell him to go back and continue thinking, instead of continuing the meaningless dispute.

Lin Shuicheng was silent.

There was no word on the other end of the phone.

As time passed by, Lin Shuicheng took a deep breath: "Teacher, I understand. Even if we do analysis and comparison at the molecular or even atomic level, we still can't determine which one is genuine and which one is fake. Because before the real No atomic or molecular level information has been entered, even if it is judged that there are differences between the two paintings at the molecular level, it can only prove that they are 'differences', and cannot be inferred from the differences."

This is like standing in front of a pair of twin brothers, asking you to judge which one is the elder brother and which one is the younger brother, but without giving any other information.

People can find some subtle differences between the twins, such as the ear on the left is bigger, but without the condition of "whether the ear is bigger or younger", they still cannot make an accurate judgment.

This is a dead end.

"Shui Cheng, the only ideas I can provide you with are here. I understand that you still want to use chemical and physical means to compare, because this is what you are good at, and it has always been the research direction—not to mention the emergence of this time. The problem is indeed in this direction. But people, when encountering things, you must not just look at the eyes, let alone dig into the corners."

Yang Zhiwei's voice softened on the other side, and it sounded a little fuzzy, as if it contained a soft sigh, "You and Xiao Chu, both of you are students I like, but you two have something in common. The problem is that they are too young, new and cutting-edge, and it is easier to get into a dead end, especially you. Remember my rules? Every time I enter the laboratory, what is the one thing I will ask you to do?"

Lin Shuicheng's voice was hoarse: "... titration. Acid-base... neutralization test. Hydrochloric acid and sodium hydroxide, indicator, phenolphthalein, methyl orange."

This is a basic reaction and experiment that every high school student or even junior high school student will have, and it is also one of the four major titration reactions that are required for entry into the Department of Chemistry.

The reagent drops drop by drop, and the color of the solution gradually becomes lighter until it becomes clear and transparent, and the moment when the acid and alkali are completely neutralized, neither more nor less will do.

At university, chemistry students are faced with more titration experiments, coordination, redox, precipitation, EDTA... Strict instructors will require students to be able to accurately measure the "last drop" to a quarter or even a tenth , has almost become a metaphysical difficulty, and it is troublesome and boring to be complained about repeatedly.

Where they can't see, heat is absorbed or released, and molecules collide and combine. Human beings use this method to explore the concentration of unknown things, face the uncanny craftsmanship of the universe with the naked eye, and make every effort to measure the unknown as accurately as possible.

Yang Zhiwei told them that this is the romance of chemistry and the interpretation of human exploration of the unknown world.

Doing a titration experiment before entering the laboratory can make them calm down.

"Your grades have always been the best. I remember you. In the first class of freshman year, you ran over to me and asked me about the structure of block copolymer assemblies. This is my doctoral project. You are an undergraduate student, but you can actually say it So many. But this is what I am most dissatisfied with you. You are too smart and too stubborn. You never want to do titration experiments well. You think it is a waste of time. Your experiments are all immersive, and the research direction is wrong. , Sometimes they are unwilling to change, and would rather find solutions to their mistakes than think of another path.”

Lin Shuicheng's lips moved, wanting to speak, but no sound came out.

"Shui Cheng, take a good look at what time it is and what you have. You are now a quantum analyst, learn to use analytical methods to resolve all these, and you can't always be immersed in the past. Chemistry is your past, your mentor I am also your past, do you understand?" Yang Zhiwei said solemnly, "You waste my time today, do you know how much it is worth? Bring me a few roast chickens for Chinese New Year this year, don't squeeze your tutor after graduation , and you should honor and respect me."

"Teacher, don't eat so much meat when you are old." Lin Shuicheng smiled, his voice hoarse, "...Thank you teacher, I will hang up here first. Thank you very much."

The phone was hung up, but Lin Shuicheng was still holding the phone, facing the darkness outside the floor-to-ceiling windows.

Their floors were high, and the lights of thousands of houses could be seen from outside. The traffic on the street was scattered like fireflies. He slightly raised his head and fell into deep thought.

Fu Luoyin had never seen Lin Shuicheng like this, or in other words, since he moved here to live with Lin Shuicheng, this person has been refreshing his understanding of him.

He is one way to him, and another way to outsiders, and he is so obedient and serious when facing elders and mentors.He is an obedient student, who has infinite respect and conviction for those who are convinced, and will make mistakes, and will silently bow his head and think about the reasons after hearing the reprimand.He was almost endearingly quiet and dignified as he concentrated on his thoughts.

This appearance is very charming, indescribably charming, and when night falls, his back facing the window is so thin and lonely.

Loneliness is a kind of temperament that Lin Shuicheng has always had. He is a nocturnal cat, jumping up and down, looking at all living beings with his eyes, and then disappearing in the afterglow of the setting sun without knowing it.

People can stay in front of it for a short time, and even touch its furry head and belly, but the cat will not follow humans home, and he will continue to return to the shadow of the evening lights.

Lin Shuicheng looked out the window, and Fu Luoyin looked at him.

Lin Shuicheng didn't know his existence, and when he realized that it was getting dark, he turned his head and walked towards the entrance, but suddenly found a black figure sitting on the sofa, subconsciously startled, and took a step back.

Fu Luoyin lit up the lighter, lowered his head and lit a menthol cigarette, the flame reflected his handsome face, and then went out.

He took a puff and remembered where he was, then quickly snuffed it out.

Fu Luoyin smiled lowly: "You just discovered me?"

Lin Shuicheng ignored him, walked up to him and sat down.

Fu Luoyin pulled him into his arms smoothly, and then the person who rushed to his arms moved, and slightly cold fingers came over, snatched the menthol cigarette from his fingertips, and bit it into his mouth.

There is also a slightly moist and warm taste on the lips and tongue on the smoke.

Lin Shuicheng bit his cigarette and bumped his elbow: "Fire."

Calling people is justifiable.

Fu Luoyin snuffed it out just now, but he wasn't angry, and stretched out his hand to continue it for him.

When the flames came on, Lin Shuicheng's eyelashes cast a shadow, his eyes sparkled, and the red tear mole at the corner of his eyes seemed to be moving and charming.

In the darkness, Fu Luoyin's voice was still low, with a slight smile: "Good student, do you smoke? Who did you learn from?"

No one in the Fu family smokes, only Fu Luoyin smokes.Just like all boys and girls have tried, he secretly tried smoking with Chu Shihan in high school, Chu Shihan choked up tears after taking a puff, and never touched a cigarette since then.Later, he learned to buy this kind of menthol cigarettes with low nicotine content, which tastes cool but refreshing.

When he first started working, he relied on coffee to keep him refreshed. Later, when he was so busy that the coffee was useless, he started smoking. Later, Chu Shihan majored in chemistry, so he took the time to make him a cigarette with a particularly high mint content, and took a puff of ice cold into his lungs. , and will not cause too much damage to the body like other styles on the market.

Lin Shuicheng's appearance of smoking was actually very standard. He took a deep breath into his lungs, and then let it out slowly.

He said: "Decompression, learned in the past two years."

Sparks flickered, and the smell of mint mixed with the fragrance of Lin Shuicheng's shower gel.The chief jumped up, and Lin Shuicheng was in Fu Luoyin's arms. He cowered and dared not move, only daring to circle around them.

Lin Shuicheng coughed: "It's so cold."

"Smoking is not good, good student." Fu Luoyin said. "Smoking less in the future."

Lin Shuicheng still ignored him, breathing lightly on his own.

Fu Luoyin suddenly felt that he was very cute and pitiful like this—even though it was already too dark to see anything clearly, he said: "Let's forget about the pressure. I'll let the seventh department take over this matter. Good student."

"I can make it." Lin Shuicheng said, "Leave me alone."

Fu Luoyin wanted to say something, but the person in his arms came over and blocked his mouth directly - also with lips.

The scent of mint approached, with a warm scent, Lin Shuicheng grabbed his collar and kissed him.

Very hard, Fu Luoyin didn't know that Lin Shuicheng still had such a strong and aggressive side, it was not he who kissed Lin Shuicheng, but Lin Shuicheng kissed him.Clutching his five fingers, pressing him on the sofa

The cow cat was startled by their sudden movements, and immediately jumped to the ground, watching them even more suspiciously, with green eyes shining in the dark.

Fu Luoyin couldn't tell why, but the moment Lin Shuicheng kissed her, he felt slightly dizzy.

He remembered that he was fined to copy when he was in junior high school. The Chinese teacher asked him to copy the missing idioms a hundred times. Among them was the word "dazzling". He brought carbon paper and stayed up all night writing under the lamp, dazzled Fascinated and dazzled... The desk lamp is very bright, shining a silent white light on the paper. It was late at night, and he stayed in Fu Kai's office. The dark night enveloped him and surrounded him from all sides of the desk lamp. , Like ghosts in the darkness.

He kissed Lin Shuicheng in the dark, as if bringing him back to so many silent nights, with only the sound of light breathing to accompany him.

Both of them nodded, Lin Shuicheng reached out to hold his hand, bit his shoulder, and said in a low voice, "Not today."

Fu Luoyin rubbed his head: "...Okay, I won't trouble you today, and I won't trouble you these few days, good student."

They didn't turn on the lights that night, Lin Shuicheng took a nap on the sofa, Fu Luoyin went to the kitchen to heat up the food that was not taken away yesterday, and asked Lin Shuicheng to get up and eat.

The kitchen light is warm yellow, neither bright nor dazzling.They were still surrounded by darkness.

Fu Luoyin said: "I'll be at No. [-] in the next few days, if you have something to call me, you can just come and find me."

Lin Shuicheng let out a "huh".

After eating, Lin Shuicheng went to his workshop and locked the chief outside.

He forgot to feed the chief. After Fu Luoyin finished eating, he found the chief screaming terribly, so he went to have a look.

Both bowls are empty and clean.

Fu Luoyin knelt down and looked at the chief, stretched out his hand, palm up: "Shake hands?"

The chief refused to hand over his claws, but also looked at him with a righteous look.

Fu Luoyin took the next best thing and decided to touch the chief's head, but this time he stretched out his hand, and the chief ran away.

Fu Luoyin still filled the head with cat food.

The chief had no backbone this time, and before he started eating, he rushed over again, stared up at him, and then buried his head in eating.

As soon as it lowered its head and began to eat cat food, Fu Luoyin reached out and stroked its head.

After such a touch, the chief will pause for a moment, as if he has encountered a major problem in the life of a cat-should he endure being touched on the head and continue to eat, or just get angry and stop eating?

After thinking for a while, it continued to eat.

Fu Luoyin touched it again.

After doing this three or four times, the cow cat finally got impatient and came over to bite him with its tail flicking.

Fu Luoyin smiled: "Your surname is Lin, right? Why do you like to bite people so much? A cat follows its owner."
