Mu Yuan turned his head to look at Director Zhou, not quite wanting to speak.

Actually...... Some people believe in sales......

It's hard to say what is going on with others, but it's hard for him to believe anyway.

Do you want a safe seller to tell you that his safe can be opened by someone else?

If you say that, who will buy it?

"Director Zhou, safety is always relative. Mu Yuandao, "Technical defense is a means, but to be truly foolproof, you have to rely on people." ”

"We've had people staring at the surveillance all the time!" Speaking of people, Director Zhou said that he had something to say, "but they didn't see anything all night, and the contents disappeared for no reason." ”

Mu Yuan said: "Video surveillance can also be changed. ”

"Change the surveillance?" Director Zhou's eyes widened, "The kind played in the movie?"

"Yes, it's difficult to operate, but it's nothing for professionals. ”

"Yes...... Our people have been watching the surveillance, so if you want to change it, there will be some movement, right?"

"To put it bluntly, the picture you see is completely a video stream fed back by the front-end camera, if you change the address to you by some means, and then send a video stream that has been prepared for a long time, as long as the switching speed is fast enough, it is really difficult for you to find the abnormality. After all, a person's ability to observe is limited, and often a fleeting anomaly may be perceived as an illusion. ”

As soon as Mu Yuan finished saying this, a young security guard next to him immediately said, "Curator, it seems to be ...... It's really a bit of a situation.,Last night this screen seemed to flicker.,It's very short.,At the time I thought it was a problem with the screen.,So I didn't say it.。 ”

"You ......" the curator was a little annoyed.

Without waiting for him to get angry, Mu Yuan said: "Director Zhou, this can't be blamed on the people who watch the surveillance, from the perspective of electronic products, it is common for the screen to flicker briefly." ”

Director Zhou was a little depressed!

He is now a stomach full of grievances, and he finally found a master who could vent, but he was cut off by Mu Yuan.

Although he can ignore Mu Yuan's opinion, after all, the security guard is also a person within them, and as a leader and a person under his education, isn't it also a normal situation?

But it's so easy to be disgusting to Mu Yuan, in case the other party doesn't care about this case, he will sit on wax.

"Squadron Mu, this is what you are talking about from beginning to end, how do you prove that the other party has tampered with the surveillance data? And the safe, I'm afraid it's not so easy to open, right?" Mr. Zheng, who had been silent for a long time, finally spoke.

Mu Yuan glanced at him and said, "The tampering of the monitoring data is very simple, so I don't need to talk about this." As for the safe you mentioned, we can go and see it on the spot. No matter how cunning the other party is, there will definitely be traces on the scene. ”

"Then let's go and see!" Director Zhou said impatiently.

"Let's finish watching the monitoring first!" Mu Yuan suddenly said, "This old brother, you just said that you noticed a screen flickering last night, when was it?"

Mu Yuan's latter sentence was said to the young security guard just now.

Although the other party is quite young, it is also relative to others, and there is nothing wrong with Mu Yuan calling him an old brother.

The young security guard was very grateful to Mu Yuan, if Mu Yuan hadn't said a word for him just now, he would definitely be scolded.

"It was about 1 a.m. Well, it must have been between 1 and 1:30, when I went to the toilet and looked at my phone. He thought for a moment and said.

Mu Yuan nodded and said, "Section Chief Li, let's start watching it from 1 o'clock in the evening." ”

Section Chief Li didn't talk nonsense, and directly adjusted according to what Mu Yuan said.

It seems that the same picture appears on the screen, except for the quiet safe, and only the decoration of the surrounding walls remains.

After a few minutes, the video stalled slightly, and then returned to normal.

Under normal circumstances, no one will pay attention to this kind of stuck, because it is normal for the surveillance video to lose frames or something during transmission, and the jamming is basically caused by this.

But Mu Yuan didn't let go of this little change, and after only a few seconds, he shouted softly: "Stop!"

Section Chief Li reacted quickly and pressed the pause button directly, but his face was a little confused.

Mu Yuan pointed to the middle of the screen and said, "Look here!"

Director Zhou and the others looked at Mu Yuan's fingers, and even Mr. Zheng, who was a little resistant to Mu Yuan, involuntarily turned his head.

The location Mu Yuan was referring to was the middle area of the safe—a display screen, about the size of a mobile phone screen.

It should be in standby mode, the display screen is very dim, but you can also vaguely see some black handwriting displayed on the screen.

Although the words could not be read clearly, everyone could understand what was displayed on them after a little thought.

It is nothing more than the current humidity, temperature, and current time.

However, because the screen on the safe occupies too small a position in the entire surveillance screen, the text on it is really difficult to distinguish.

"Squadron Mu, this ...... What can you see?" asked Vice Minister Li curiously.

Mu Yuan smiled and didn't answer directly, but said, "Section Chief Li, you move the picture forward by 1 minute." ”

Section Chief Li did so.

All eyes were fixed on that small screen, and they all knew that there must be something unusual changing in this minute.

Time passed slowly, and Minister Li and the others looked at it for more than ten seconds, and then gave up completely, because there was really nothing to be seen on it.

The blurry handwriting was still so blurry, even if they stared at the round eyes, what they saw was still blurry.

A minute passed quickly, and Lai Yang suddenly said in surprise: "Mu team! ”

The corners of Mu Yuan's mouth curled slightly, and he turned his head and asked, "What do you see?"

"The time is wrong. ”

Mr. Zheng looked at Lai Yang's face for two seconds, then looked at the display screen again, and said very directly: "This police officer, can you read the words on this clearly? I think my eyesight is not bad, but I also don't recognize the time on it." ”

"I don't recognize it either!" Lai Yang said solemnly, "But now that we are handling a case, we don't need to recognize the time, as long as we can see that there is a problem with the time." ”

Everyone's brains were a little dizzy......

"It's really hard to tell the numbers on it. But there is one number that is still recognizable, and that is '1'. Although the other numbers are indistinguishable, if there is a jump, it can still be seen. And just now, on the penultimate digit of this time, that is, the tenth digit of the second, from the last time '1' disappeared, to the next time '1' appeared, there should be at least about 50 seconds in between, but just now, the interval between the two '1's is only 20 seconds. ”

Everyone present, except for Mu Yuan, all fell into deep thought.

Lai Yang's words they couldn't refute, although the screen was small, the slender '1' did have the conditions for recognition.

If it is really as Lai Yang said, then this is ironclad evidence that the video has been tampered with!

Time has jumped, it's not that the video has been changed, what else can it be?

After figuring it out, they couldn't help but look at Mu Yuan, and at the same time at Lai Yang.

This kind of thing, to put it bluntly, is indeed very ordinary, but such a detailed thing, it is an ability to be discovered.

Judging from the situation where this detail was discovered just now, Mu Yuan's ability to observe details crushed everyone present, because he could see it with his own naked eyes.

As for Lai Yang, although he also observed it, he was reminded by Mu Yuan.

That's not to mention the others, who are all scum.

At least in terms of the observation and control of details, they are completely defeated!

It seems that not everyone can do the job of a policeman. Especially the criminal police, without two brushes, it is estimated that they only have the share of soy sauce.

"Okay, now let's go and see it. Mu Yuan said calmly.

"Okay! Director Zhou immediately stepped forward and took two steps, making a look of leading the way.

At this moment, he has a little more expectation in his heart, perhaps...... Mu Yuan is really as magical as Feng Ju said.

As long as he can solve this case, recover the lost cultural relics, and let him beg his grandfather to sue his grandmother, let alone just show humility and lead the way.

The group walked out of the monitoring room, and Section Chief Li also followed.

After all, he is the chief of the security section, and he is directly responsible for such an incident.

Soon, they walked through a walkway and came to the third exhibition hall that Director Zhou had mentioned earlier.

A cordon had been put up at the gate, and there were two security guards guarding the door, and there was no one inside.

"Have you ever been in?" Standing outside the door, Mu Yuan asked casually.

Director Zhou said: "I went in! At that time, the museum was to be opened, and it was necessary to open the safe to take out the cultural relics. ”

"How many people have been in?"

"Probably...... A dozen of them. Director Zhou smiled.

This number is a bit much, although Director Zhou doesn't know much about investigating and solving cases, but he has never eaten pork and has always seen a pig run, right? These more than ten people walked around the scene of the crime, and it is estimated that even if the suspect left any traces, it was almost destroyed.

Mu Yuan glanced at the exhibition hall, didn't speak, pulled up the cordon, and walked in.

The others were a little dumbfounded, should they follow up or not?

However, they didn't dwell on it for too long, and when Vice Minister Li and the others saw that Lai Yang and Xiao Yu, the two criminal policemen, were also standing outside the cordon, they were completely settled.

Although more than 10 people have stepped on it before, it is not possible to relax the control of the scene, just go in and step on it again, right? Even if you want to step on it, you have to wait for professionals to complete the scene inspection.

Thinking of the on-site inspection, Mr. Zheng, who knew something about this industry, frowned.

"You Mu squadron, you should be scouts, right? Shouldn't on-site investigation be done by technicians?" asked Mr. Zheng.

Lai Yang glanced at him and said, "Although our Mu squadron is not a professional in field surveys, his ability in this area is more professional than that of professionals. ”

Ask for a small monthly pass......
