Although some people always say that high technology is unreliable. I can only say that you don’t know how to use it or have never seen it. As time goes by, high technology is an inevitable trend, so high technology will definitely become more and more popular.

The more reliable it is, the more unreliable it is. People who say this are basically out of date. It is true.

For example, if you compare an old-fashioned mechanical safe with a safe that has infrared sensors, vibration sensors, various biometrics, internal self-checks, and various surveillance cameras around it, what do you think?

Safer? High technology is unreliable? That’s nonsense. You may not even be able to get close to the latter. So you still tell me that high technology is unreliable?

As it is now, the safe that Fan Keqin is inspecting at this time is already the top type of safe in this era. But in Fan Keqin's eyes, it is still elementary. The principle and so on,

It's the simplest.

Carefully and patiently, he checked with a magnifying glass for five or six minutes. Fan Keqin gently patted Zhuang Xiaoman's hand holding the flashlight, indicating that she could turn it off. Then he simply said four words:

"Technical unlocking."

Although what he said was short, several people present were experts, including Yu Runze, and they all understood what he meant. It was like a clever thief who wanted to break into a house. Although he didn't have a key, he still used wire and steel.

Using something like a thread, you can open the lock with your own lock-picking skills. This is called technical lock-picking.

Fan Keqin looked at the password knob again, and then said: "Is the current position of this password knob the same as the position that Brother Runze adjusted when he rechecked and opened it?"

"Yes." Yu Runze said: "After I opened it and discovered the problem, I immediately sealed the room. There is no way anyone can touch it again."

Fan Keqin nodded and said: "Brother Runze said before that there are four keys in total, three are in the inspection room and one is on the director's body."

Yu Runze replied: "Yes."

Fan Keqin asked: "What about the situation when the administrator is at work?"

"Oh." Yu Runze said: "I also had this suspicion at the time, but it is unlikely that the administrator has a problem. They are all people who know the basics, and safe No. 1 is a top priority, so as long as it is during working hours,

There must be at least two people inside to supervise each other. When eating, someone will come to deliver it, and there is a toilet inside. So it is most likely one of them." As he spoke, he pointed to the small door on the side.

.

Lao Qi happened to be nearby, stretched out his hand to open the door, looked inside, and turned around and said: "Well, it's a closed toilet. But... if one person goes to the toilet, the other person will still get a separate space outside.

.”

Fan Keqin waved his hand and said: "It's impossible, unless someone has diarrhea and takes a long time to go to the toilet. The situation at that time was that it was necessary to technically open the lock, and then steal the files inside, which must be read and restored to their original state.

In addition, he also discovered the secret mark and tried to restore it. This

The process cannot be too short, and it will take a few minutes if you are nimble. As long as a person goes to the toilet and comes out in the middle, or if an outsider comes in during this time, he may be exposed instantly. Therefore, I analyze that there is a high probability that he does not work during the day.

It’s really too risky for people to do it.”

Lao Qi nodded and said: "That makes sense. Is it really possible that the time is night?"

Fan Keqin didn't say anything, but looked at Yu Runze and said, "Brother Runze, please take us to see those two footprints again."

"Okay." Yu Runze said, "It's not too far, just turn next to it." As he spoke, he led them out.

As soon as I walked out of the door, I saw the young woman named Xiao Ou waiting at the door with a document bag. After meeting Fan Keqin and his party, she said hello, then handed the document to Fan Keqin and said: "

Commander Fan, this is the evidence collection photo taken at that time, take a look, do you have any other instructions?"

After Fan Keqin took it, he opened it and took out a stack of photos, looked at it briefly and said, "Thank you, I don't need anything else for now."

The young woman Xiao Ou said: "Okay, sirs, please be busy, I'll go upstairs first." After saying that, she turned around and walked along the corridor.

Fan Keqin played with the photos for a while, and there were indeed photos of safes, indoor conditions, etc. There were also several photos of footprints. Some were close-ups and some were long shots. However, Fan Keqin could tell after a little analysis that there were a total of

There are just two footprints.

After looking at it, Fan Keqin temporarily handed the photo to Zhuang Xiaoman and said, "Let's go and take a look."

Yu Runze agreed again, and led everyone around a corner, to the corridor on the side of the building, and then entered another door blocked by guards. Yu Runze pointed to the door lock and said: "Brother Keqin, at that time we

I found that the door lock of this door was also unlocked."

"Yes." Fan Keqin nodded to show that he understood, but did not say anything about his opinion, and then followed the other person in.

Fan Keqin saw at a glance the two footprints on the window sill and the slightest trace of a footprint on the ground.

Yu Runze said with some regret: "There are actually two footprints on the ground. Relatively speaking, one is deep and the other is shallow. But now two days have passed, although we have blocked the place, the shallow footprint can no longer be seen.

Already."

Fan Keqin said: "It doesn't matter, there are still photos. Xiaoman, give me the overall photo."

"Yes." Zhuang Xiaoman picked one in his hand and handed one to Fan Keqin. After taking it, the latter looked at the photo and began to compare the traces on the ground. He quickly determined that the second footprint had "disappeared"

position. He took out a banknote from his pocket and placed it next to it.

Fan Keqin stopped talking and returned the photo to Zhuang Xiaoman. Then he took the magnifying glass again and began to squat on the ground in detail and observe the footprints. He looked at all the footprints, even the window frame.

The floor, doors, etc. were all checked again and again.

Finally, Fan Keqin put away the magnifying glass, looked at Yu Runze and said: "The footprints on the window sill are both positive and negative, both of the left foot. This shows that he always walked this way when he came in and out. How could a normal staff member do this?"

The trick was to climb through the window. So it must have been left by someone with evil intentions. That’s why Brother Runze said that the person who left the footprints must be a ghost. It’s also based on this reason, right?”
