Super hang up system

Sherman frowned and said, "I'm afraid it will be very difficult."

Liu Xing said: "After the isotope age is determined, maybe I will have a solution."

After waiting for a while, Sherman's assistant came in with an ugly face holding the drawing and the measurement results. From her pale face, she could already guess the final result of the measurement.

"Come on, no matter what kind of bad news it is, I can bear it." Sherman looked at the assistant with a serious expression.

The assistant said word by word: "After testing, the creation time of this painting is no more than one year, and it is an out-and-out fake."

Sherman sighed deeply: "Leave the painting, you go out first, remember, it must be kept secret."

After the assistant left, Sherman looked at Liu Xing and said, "Now please tell me, Mr. Liu, what can you do to help me figure out the whole thing."

Isotopic dating, although the age of this painting can be determined, but the dating is not accurate. For example, the result of this fake is no more than one year old, but the exact time cannot be determined.

What technology cannot do, Liu Xing can do, this is his trump card.

Through the identification technique, Liu Xing knew when the painting was completed.

"If I'm not mistaken, the real completion time of this painting is about a month, so things should happen within this month, so that we can narrow the scope a lot."

"Within a month? This range is still too broad. Are there any other clues?" Sherman asked after thinking about it.

"Yes," Liu Xing said firmly.

Before the measurement results came out, Liu Xing had been thinking about this problem, but he never thought of any valuable clues.

But the subtle difference from the original work has been lingering in his mind, and he always feels that there is a thread that can be grasped within reach, but he can't grasp it all the time.

Until later, when a ray of sunlight came in from the window and just fell on a painting in the corner, this scene gave him a flash of inspiration, grasped the thread, and understood.

Sherman looked at Liu Xing full of expectations, wondering if he had any special clues.

"Has the curator ever thought about why this whole painting is perfectly imitated, but this place has gone wrong?"

Hearing Liu Xing's question, curator Sherman fell into deep thought, his brows were tightly frowned, his eyes kept on the fake painting, and he couldn't leave for a long time.

But at last he sighed and shook his head.

"I don't have a clue."

"Actually, I discovered the problem by accident." Liu Xing said slowly: "Since the other party can imitate the Mona Lisa so perfectly, it means that the painter is very familiar with the Mona Lisa, so this shouldn't happen. mistakes, then there must be a reason for such an accident.”

"So what's the reason?" Sherman asked anxiously.

Liu Xing pointed out the window and said, "Because of the sunshine."

"Sunshine?" Sherman asked puzzled.

"The reason for this error is the sunshine." Liu Xing said with certainty.

"I don't quite understand what you mean," Sherman said, shaking his head.

Liu Xing said, "Are tourists allowed to copy paintings here?"

Sherman nodded and said: "This is allowed. There is a special time every day for students from the Academy of Fine Arts, or other painters to copy paintings."

Liu Xing nodded and said, "If I'm not mistaken, this painting should have been copied on the spot, and the blemish should be caused by the refraction of light from the sunlight on the original painting."

Sherman immediately retorted: "This is impossible. The position where the Mona Lisa is displayed will not be affected by the sun, and such an important painting cannot be exposed to the sun."

Liu Xing said, "Maybe it's because of some special reason?"

Bai Shuangshuang interrupted suddenly: "Such an important place must be monitored, and you will know if you take a look."

"That's right, such a simple thing, what do you want to do so complicated." Liu Xing asked Sherman, "Is there monitoring?"

Sherman said: "Of course there are, let's go and see now."

The opening hours of Mona Lisa painting copying are fixed, from [-]:[-] to [-]:[-] pm, so you only need to check the monitoring for these two hours.

So several people surrounded the monitoring room and began to tune forward to watch the video of the camera facing the painting.

After looking at it for a few minutes, Liu Xing said: "Hurry up, it's a waste of time to look at it this way, we just need to see if there is any sunlight hitting the painting."

Sherman nodded to the security guard, signaling him to speed up the playback.

Liu Xing said: "Hurry up, hurry up, yes, hurry up."

Under Liu Xing's signal, the playback speed was accelerated to eight times, and the time began to advance day by day.

"Stop!" Liu Xing shouted suddenly: "Back back, keep pushing, and back a little more, okay, here it is."

The monitor screen stopped at 27:22 p.m. 5 days later, and a very inconspicuous light spot appeared at the place where the counterfeit had a problem. This light spot lasted for about [-] minutes, and then it never appeared again.

Liu Xing pointed to the light spot and said, "It seems that there is a problem here."

Sherman looked at the inexplicable light spot that appeared on the panic screen in surprise, but couldn't figure out where the light spot came from.

Liu Xing said: "Don't worry about where the light spots come from. That's not the point. The point is that we have found the cause and the exact time. Now we just need to look it up and see who came to copy the painting on this day, and we can shrink it again. scope of investigation."

Sherman said: "We will have detailed records of all the people who came to copy it. It will not be difficult to find it, but there are many people who come to copy it every day. How can we know who painted this painting?"

Bai Shuangshuang interjected: "It's very simple, just see who is drawing the problematic part when there is a spot of light, and you will know."

Liu Xing gave Bai Shuangshuang a thumbs up, Bai Shuangshuang was praised and smiled sweetly.

Sherman had security pull up another monitor that could see the scene around the entire Mona Lisa and step back to the same time.

Everyone can see at a glance that during this time period, among so many copyists, there is exactly one person's brush that is painting that place.

"It seems that this is the person we are looking for." Liu Xing pointed to the girl who was seriously copying in the picture.

Sherman immediately called his assistant and pointed to the girl in the surveillance screen.

"Go and check, this girl's information will be sent to my office in a while."

After the assistant left, Liu Xing and others returned to Sherman's office.

"Mr. Liu Xing is really grateful to you this time. If it weren't for you, the entire Louvre would not know how long it would have been deceived."

Sherman's face was full of gratitude, which seemed very sincere.

Liu Xing said: "Since Director Sherman and Professor Ge are good friends, of course I will not stand idly by."

Professor Ge also seemed very happy with Liu Xing's statement.

Soon the assistant brought the results.

"Her name is Avril Lavigne, and she is a senior student at the Paris Academy of Fine Arts. This is her registration information."

"Understood, you go out." Sherman waved his hand, signaling the assistant to leave.

Sherman handed the information to Liu Xing and said, "You should take a look. We are getting old and our brains are not as fast as your young people."

Liu Xing smiled, took the documents, checked them carefully, and put them down after a while.

"Judging from the data, Avril Lavigne's registration record expired half a month ago, that is to say, the painting should be completed half a month ago, so the time when the real painting was dropped is half a month ago to now within this time period."

Sherman thought for a while and said, "There are a lot of tourists during the day, so it is definitely impossible to switch bags. Only after the museum is closed at night can crimes be committed."

Liu Xing said: "Looks like I have to go to the surveillance room to take a look at the surveillance video after the closure of the museum in the past half a month."

So the group hurried to the monitoring room again and began to check the monitoring of the last half month.

After watching for a while, Liu Xing suddenly asked: "Wait a minute, why is there a sky missing in the middle?"

The security staff replied: "It happened that the surveillance equipment of the entire museum was being upgraded that day, so there is no video of that day."

Liu Xing and Sherman looked at each other: "It should be the problem that happened today."

Sherman frowned and said, "Without video surveillance, it's very difficult to find out who did it."

Liu Xing thought for a while and said: "It seems that we still have to start with Avril Lavigne and see where her paintings go."

After Liu Xing finished speaking, he found that both Sherman and Professor Ge were looking at him.

"Why are you looking at me like this?" A bad premonition rose in his heart.

Sherman said with a smile: "Such an important matter, of course, can only be entrusted to you. You can't let us two old guys do it."

"Hey..." Liu Xing sighed deeply, and instantly felt that he had fallen into a wolf's den, no, it should be a fox's den, two cunning old foxes.

Bai Shuangshuang was rather interested: "Paris Academy of Fine Arts, why don't you go and have a look."

Professor Ge also persuaded: "You should bother more about this matter, and help my old friend."

Liu Xing had no choice but to agree. Originally, he was helping Bai Shuangshuang to find his memory, but now it turned into an investigation, which is really hard to guard against.

With the relationship between him and Professor Ge, it would be unreasonable not to help. It seems that I have to work harder.

The Paris Academy of Fine Arts stands on the left bank of the Seine, not too far away from the Louvre. It is the world's top palace-level academy of fine arts, and has a high level of influence in the world's art circles.

Xu Beihong, Pan Yuliang, Wu Guanzhong, the older generation of Chinese oil painters all graduated from this school.

The academy has brought together a large number of extremely talented young people, who are likely to grow into world-renowned artists in the future.
