Although some people always say that high technology is unreliable. All I can say is that you don’t know how to use it, or you haven’t seen it. As time goes by, high technology is an inevitable trend, so high technology will definitely become more and more reliable. Still unreliable? It is true that the people who say this are basically all behind the times.
For example, if you compare an old-fashioned mechanical safe with a safe that has infrared sensors, vibration sensors, various biometrics, internal self-tests, and various surveillance cameras around it, what do you think? More secure? High technology is unreliable? Just 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 safe in this era. But in Fan Keqin's eyes, they are just junior. The principle is 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 it meant. It's like a clever thief who wants to break into a house. Although he doesn't have a key, he still uses iron wire, steel wire and other things to open the lock with his own lock-picking skills. This is called technical unlocking.
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 opening it and discovering the problem, we 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 said: "What about the administrator's situation when he is at work?"
"Oh." Yu Runze said: "I also had this suspicion at the time, but it is unlikely that there is a problem with the administrators. They are all people who know the ins and outs, and this No. 1 safe is the 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 technically necessary to 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 recover it. This process cannot be too short, and it will take a few minutes if you are nimble. As long as people who go to the toilet come out in the middle, or if there are outsiders coming in during this time, he can It will be exposed instantly. Therefore, I analyze that there is a high probability that it cannot be done by people who work during the day. It would be too risky."
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, take us to see those two footprints again."
"Okay." Yu Runze said, "It's not too far, just turn around." As he spoke, he led them out.
As soon as he walked out of the door, he saw the young woman named Xiao Ou waiting at the door with a document bag. After meeting Fan Keqin and his party, he said hello, then handed the document to Fan Keqin and said: "Sir Fan, these are the evidence collection photos 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 the safe, indoor conditions, etc. inside. There are also several photos of footprints. There are close-ups and long shots. However, Fan Keqin can tell after a little analysis 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 and take a look."
Yu Runze agreed again and led everyone around a corner to the corridor on the side of the building, then entered 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 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 party in.
Fan Keqin saw two footprints on the windowsill at a glance. And there is a slight mark on the ground that can be seen as a footprint.
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. ”
Fan Keqin said: "It doesn't matter, there are still photos. Xiaoman, give me the overall photo."
"Yes." Zhuang Xiaoman selected one in his hand and handed one 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 "disappeared" footprint was quickly determined. And he took out a banknote from his pocket and put it next to him.
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. I looked at all the footprints, and even checked the window frames, the ground, the door, etc. all over again.
Finally, Fan Keqin put away the magnifying glass, looked at Yu Runze and said: "The footprints on the window sill are the same as those of the left foot. This shows that he always walked this way when he came in and out. How could a normal worker do this?" The trick was to climb through the window. So it must have been left by someone with evil intentions, so Brother Runze said that the person who left the footprints must be a ghost. It is also based on this reason, right?"
"That's right." Yu Runze said: "And this room is vacant. No one comes because there is nothing in it. Now that footprints are found, it must be left by ghosts."
