Although some people always say that what high-tech is not reliable. All I can say is that you won't use it, or you haven't seen it. With the passage of time, high technology is an inevitable trend, so high technology will become more and more reliable. Still unreliable? It's true that the people who say this are basically all outdated.

For example, it is an old-fashioned mechanical safe, compared with a safe with infrared induction, vibration induction, various biometrics, plus internal self-inspection, and various surveillance cameras around, which one do you say is safer? Still high-tech unreliable? That's. You may not even be able to get close to the latter. So you're still telling me, high-tech can't be trusted?

Like now, the safe that Fan Keqin is checking at this time is already the top type of safe in this era. But in Fan Keqin's eyes, it is just rudimentary. The principle or something, the most simple.

Carefully, patiently using a magnifying glass, checked for five or six minutes, Fan Keqin gently patted Zhuang Xiaoman's hand holding the flashlight, signaling that she could turn it off. Then he just said four words briefly: "Technology unlocks." ”

Although he said it briefly, several people present were experts, including Yu Runze, and they all understood what it meant. It's like a clever burglar who wants to burglarize, and although he doesn't have a key, he still uses wire, steel wire and other things to open the lock with his own lock-picking skills. This is called technical unlocking.

Fan Keqin then looked at the password knob again, and then said: "This password knob, is the current position the position adjusted by Brother Runze when he rechecked and opened it?" ”

"Yes." Yu Runze said: "After opening it and discovering the problem, I immediately sealed off the house. No one will ever touch it again. ”

Fan Keqin nodded and said, "Brother Runze said before that there are a total of four keys, three in the supervision room and one on the director. ”

Yu Runze replied, "Yes." ”

Fan Keqin said: "What about the situation of the administrator when he goes to work?" ”

"Oh." Yu Runze said: "I also had this suspicion at the time, but it is unlikely that the administrator will have a problem, all of them are people who know the roots, and this No. 1 safe is the top priority, so as long as it is working hours, there must be at least two people inside to supervise each other." When eating, someone also comes to deliver it, and there is a toilet inside. So it's too likely to be one of them. As he spoke, he pointed to the small door on the side.

Lao Qi happened to be next to him, stretched out his hand to open the door, looked inside, turned his head and said, "Well, closed toilet." But...... If there is a person who 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 it takes a long time to go to the toilet." At that time, the situation was that the technical unlocking, and then the theft of the documents inside, had to be looked through, and it had to be restored to its original position, and he also found the secret mark, and tried to restore it. This process can't be too short, and it can take a few minutes if you're quick with your hands and feet. As long as the person who goes to the toilet comes out halfway, or if an outsider wants to come in during this time, he may be exposed instantly. Therefore, I analyze that it is most likely not something that people who work during the day can do, which is really too risky. ”

Lao Qi nodded and said, "Reasonable, is it really possible that the time is night?" ”

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

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

As a result, as soon as I went out, I saw that the young woman named Xiaoou was waiting at the door with a document bag. After seeing Fan Keqin and his party, he said hello, then handed the document to Fan Keqin, and said, "Chief Fan, this is a photo of evidence collection taken at that time, take a look, do you have any other instructions?" ”

After Fan Keqin took it, he opened it and pulled out a stack of photos, looked at it slightly, and said, "Thank you, I don't need anything for the time being." ”

The young woman Xiao Ou said: "Okay, then the chiefs are busy, I'll go upstairs first." With that, he turned and walked down the hallway.

Fan Keqin fiddled with the photo for a while, and there were indeed photos of the safe, the interior, and so on. There are also several photographs of footprints. There are close-ups, there are vistas. However, Fan Keqin can tell that there are only two footprints in total.

After looking at it, Fan Keqin temporarily handed the photo to Zhuang Xiaoman and said, "Let's go to the field to see." ”

Yu Runze agreed again, led everyone to turn a corner, came to the corridor on the side of the building, and followed into another door blocked by guards. Yu Runze pointed to the door lock and said, "Brother Keqin, at that time, we found that the door lock of this door was also open. ”

"Hmm." Fan Keqin nodded to indicate that he understood, but did not say anything of his opinion, and then followed the other party in.

Fan Keqin saw at a glance the two footprints on the windowsill. and a slight trace of footprints on the ground.

Yu Runze said with some regret: "There are actually two footprints on the ground, one deep and one shallow, but now that two days have passed, although we have sealed off here, the shallow footprints are no longer visible." ”

Fan Keqin said: "It's okay, there are photos." Xiaoman, give me the whole picture. ”

"Yes." Zhuang Xiaoman picked it in his hand and handed one of them to Fan Keqin. After the latter took it, he looked at the photo and began to compare the marks on the ground. The location of the second, which had already "disappeared" footprints, was quickly determined. And he took out a bill from his pocket and put it aside.

Fan Keqin stopped talking, but returned the photo to Zhuang Xiaoman, and then took the magnifying glass again, and began to squat on the ground in detail, observing the footprints. I looked at all the footprints, and even the window frames, floors, and doors were all double-checked.

In the end, Fan Keqin put away the magnifying glass, looked at Yu Runze and said: "The footprints on the windowsill are positive and backward, all of them are left feet, which shows that he walked this way when he came out and went in, and how could a normal staff use the trick of turning the window." So it must have been left by a wrongdoer, so what Brother Runze said, this person who left footprints must be a ghost, and it is also based on this reason, right? ”

"That's right." Yu Runze said: "And this room is vacant, and no one comes, because there is nothing in it." Now that the footprints have been found, they must have been left by ghosts. ”
