Mu Yuan turned his head and looked at Director Zhou, not wanting to speak very much.

Actually... some people believe in sales...

It is hard to say what other people are doing, but it is difficult for him to believe it anyway.

Could it be that if a person who sells a safe tells you that someone else can open his safe? Isn’t it nonsense?

If you really say that, who will buy it?

"Director Zhou, safety is always relative." Mu Yuandao, "Technical defense is a means, but to be foolproof, one has to rely on others to truly achieve perfection."

"We have been watching the surveillance monitor!" As soon as people were mentioned, Director Zhou said he had something to say, "but they didn't see anything all night, and the things inside disappeared for no reason."

Mu Yuandao: "Video surveillance can also be changed."

"Change the surveillance?" Director Zhou's eyes widened, "What kind of performance in the movie?"

"Yes! Although it is difficult to operate, it is nothing to professionals."

"But... our people have been watching the surveillance. If there is any change, there will be some movement?"

"To put it bluntly, the picture you see is completely a video stream feedback from the front-end camera. If you change the address through some means and then transfer a video stream that has been prepared long ago, as long as the switching speed is fast enough, it is indeed difficult for you to find anomalies. After all, a person's observation ability is limited, and anomalies that pass by may be considered an illusion."

As soon as Mu Yuan finished speaking, a young security guard next to him immediately said, "Director, it seems... it's really a bit of a situation. The screen seemed to flash a little last night, very short. At that time, I thought it was a problem with the screen, so I didn't say it."

"You..." The director was a little angry.

Before he got angry, Mu Yuan said, "Director Zhou, this cannot be blamed on the people who watch the surveillance. From the perspective of electronic products, it is common for the screen to flash for a short time."

Director Zhou was a little depressed!

He is now full of frustration. He finally found a person to vent, but was cut off by Mu Yuan.

Although he could ignore Mu Yuan's opinion, the security guard was also a member of them. Isn't it normal for the leaders to educate their subordinates?

But this makes Mu Yuan so disgusting. If the other party is not concerned about the case, he will be waxed.

"Mu Squadron, you are talking from beginning to end. How do you prove that the other party has tampered with the monitoring data? There is also a safe, which is probably 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 surveillance data is very simple, so I don't need to mention this. As for the safe issue you mentioned, we can go to the scene. No matter how cunning the other party is, there will definitely be traces on the scene."

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

"Prefer to finish watching the surveillance first!" Mu Yuan suddenly said, "Brother, you just said that you found a screen flashing last night. At about when?"

The next sentence Mu Yuan said to the young security guard just now.

Although the other party is quite young, it is also compared to others. Mu Yuan calls him "Brother" and there is nothing wrong with it.

The young security guard was very grateful to Mu Yuan. If Mu Yuan hadn't said something for him, he would have been criticized.

"It was almost 1 a.m. Well, it should be between 1 a.m. and 1:30. At that time, I went to the bathroom and looked at my phone." He thought about it carefully and said.

Mu Yuan nodded and said, "Secretary Li, then start watching from 1 pm."

Section Chief Li did not say nonsense, and made adjustments directly as Mu Yuan said.

It seemed as if the unchanging picture appeared on the screen, except for the quiet safe, only the decoration of the surrounding walls was left.

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

Generally speaking, no one will pay attention to this kind of lag, because it is normal for surveillance video to lose frames during transmission, and lag is basically caused by this.

But Mu Yuan did not let go of this small change. After only a few seconds, he shouted softly: "Stop!"

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

Mu Yuan pointed to the middle of the screen and said, "Look at this place!"

Director Zhou and others looked at Mu Yuan's fingers, and even Mr. Zheng, who was a little resistant to Mu Yuan, couldn't help but turn his head.

The location Mu Yuan pointed to was the middle area of ​​the safe - a display screen, which was 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 I couldn't see the words clearly, everyone could understand what was displayed on it after thinking about it.

It's just about current humidity, temperature and current time.

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

"Squadron Mu, what can I see...?" Vice Minister Li asked curiously.

Mu Yuan smiled and did not answer directly, but said, "Secretary Li, please adjust the picture forward for 1 minute."

Section Chief Li did as he did.

Everyone stared at the small screen, and they all knew that there must be some abnormal changes within this minute.

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

The vague handwriting is still so blurry, even if they stare at the eyes, they still see it in a blur.

A minute passed quickly, and Lai Yang suddenly said in surprise: "Captain Mu! I can see it."

Mu Yuan raised his lips slightly, turned his head and asked, "What did you see?"

"Time! The time above is wrong."

Mr. Zheng's eyes stayed on Lai Yang's face for two seconds, then looked at the display screen and said directly: "This police officer, can you see the words on it clearly? I think my eyesight is pretty good, but I also can't recognize the time on it."

"I can't recognize it either!" Lai Yang said seriously, "But now we are handling the case, and we don't need to recognize it. As long as we can see that there is something wrong with this time."

Everyone was a little dizzy...

"The numbers on this are indeed difficult to distinguish. But there is one number that can still be identified, that is '1'. Although other numbers cannot be distinguished, they can still be seen if there is a jump. Just now, the second last digit of this time, that is, the ten digits of seconds, disappeared from the last '1' to the next '1', and the interval between the next '1' should be at least about 50 seconds, but just now, the interval between the two '1' was only 20 seconds."

All the people present, except Mu Yuan, fell into deep thought.

Lai Yang's words could not be refuted. Although the screen was small, the slim '1' did have the conditions for identification.

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

Time is beating, what else can it be if the video is changed?

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

This kind of thing is indeed very ordinary after putting it bluntly, but if you can find such details, it is a kind of ability.

Judging from the situation where he discovered this detail just now, Mu Yuan's detailed observation ability crushed everyone present because he could see it completely based on his naked eyes.

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

Not to mention the others, they are all trash.

At least in terms of observing and controlling the details, they were completely defeated!

It seems that not everyone can do the job of a policeman. Especially the detective, who has no choice but to make soy sauce without making any tricks.

"Okay! Let's go to the scene now." Mu Yuan said calmly.

"Okay! Go here." Director Zhou immediately stepped forward and took two steps, looking like he was leading the way.

At this moment, he felt a little more anticipation in his heart. Perhaps... Mu Yuan was really as magical as Director Feng said.

As long as the case can be solved, the lost cultural relics can be recovered, and he will beg his grandfather to sue his grandmother, let alone just behave with a more humble attitude.

The group left the monitoring room, and Section Chief Li followed.

After all, he is the head of the security section, and he is directly responsible for such a matter.

Soon, they walked through a walkway and arrived at the exhibition hall No. 3 that Director Zhou had mentioned earlier.

The guard belt was already raised at the gate, and two security guards were guarding the gate, and there was no one inside.

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

Director Zhou said: "I've been in! I'm going to open a museum at that time, and I need to open a safe to take out the cultural relics."

“How many people have been in?”

"About... ten." Director Zhou smiled embarrassedly.

There are a lot of people here. Although Director Zhou is not very familiar with investigating and solving the case, he has never eaten pork and has always seen the pig run. These more than ten people walked around the crime scene. I guess even if the suspect left any trace, it would have been almost destroyed.

Mu Yuan glanced at the exhibition hall, didn't say anything, pulled up the warning belt and walked in.

The others were a little stunned. Should they follow in? Or not?

However, they did not struggle for too long. When Vice Minister Li and others saw that Lai Yang and Xiao Yu, the two criminal police officers, were also standing outside the guard belt, they were completely settled.

Although more than ten people have stepped in before, we cannot relax the control of the scene, and just go in and step on it again, right? Even if we have to step on it, we have to wait for the professionals to complete the on-site inspection.

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

"You Mu Squadron should be an investigator, right? Shouldn't on-site investigation be something that technical personnel do?" Mr. Zheng asked.

Lai Yang glanced at him and said, "Although our Mu Squadron is not a professional in conducting surveys, his ability in this area is more professional than professionals."
