Hearing my question, Mu Zihan smiled slightly, and said while drinking tea: "Siyuan, this is a blind spot of inertial thinking. The pen "Fun" Pavilion www.biquge.info we generally comment on the number of floors of a building, and they are calculated according to the indoor floors. However, in fact, all buildings with roofs have an open-air floor. In the case of the building of this detention center, the reason why it is said to be the third floor is because the first to third floors can accommodate people. However, in fact, above the third floor, there is another floor, that is, the roof of the building, although it cannot live people, but it is enough for people to walk on it. ”

"Oh, the fourth floor you mentioned turned out to be the rooftop." I said suddenly. And in this way, I also understand.

It turned out that the location where the footsteps and dragging sounds were made was on the roof, so the suspect on the third floor could hear those sounds in the dead of night. Moreover, since the roof is generally not equipped with surveillance. Therefore, at the time when the footsteps are heard, investigate all the surveillance videos, and no human figure will be found.

However, then I had another question: "Although your statement seems to make sense, if the footsteps are coming from the ceiling overhead, ordinary people can still hear it." ”

"You're right, but only if it's coming from the ceiling directly above. But what if it's not directly above? In that case, you will notice that the sound is coming from a higher position, but you can't completely conclude that it must be upstairs. In addition, in the empty detention center in the middle of the night, there would be echoes when walking, and I thought that I was already living on the top floor of the building. Then, people will subconsciously judge these sounds as coming from outside the door. Mu Zihan explained.

Immediately after, he added: "Of course, in order to do this, you must first be very familiar with the internal structure of the third floor of the detention center, even if you are on the roof, you can accurately identify the location of the corridor and the cell, and avoid walking directly above the cell." Therefore, if my inference is correct, this ghost is not a suspect detained in the detention center, but a staff member who has worked in that detention center for many years. ”

"Oh, I see." Now I understand it completely. I have to say that Mu Zihan is really good at these reverse thinking reasoning, just based on Lin Shixuan's description of the phenomenon, he can deduce so many things, as if he has personally investigated it.

Seeing that there was nothing left to talk about, Mu Zihan looked at the time, stood up and stretched, and said, "As for who the person who pretends to be a ghost, I think with Lin Shixuan's ability, he can find out quickly, so we don't have to worry about it." It's not too early, pack up and go to bed, I'm tired all day today. ”

After saying that, he ignored me and went straight to the bathroom to wash up while yawning.

But not long after Mu Zihan walked into the bathroom, the mobile phone he left on the coffee table suddenly rang, I picked it up and found that it was actually a call from Lin Shixuan, who had just left not long ago.

"Zihan, Lin Shixuan's phone." I yelled at the bathroom and got up to get my phone in for him to answer.

"I'll wash my hair, Lin Shixuan's phone, you can answer it." Mu Zihan's urn sounded and the sound of urn gas came from the bathroom. This guy too, I don't usually know how to wash my hair for a few days, and I'm going to sleep today, and I'm actually washing my hair? I guess he couldn't stand it when he saw his hair in the mirror.

However, what is the matter with Lin Shixuan? Didn't he find out the truth about the strange things in the detention center? Why did you call so quickly? Could it be that the man who pretended to be a ghost was caught so quickly? It's impossible, it's only been such a short time, and it is estimated that no one else should have arrived at the detention center yet.

Since Mu Zihan asked me to answer, I unceremoniously satisfied my curiosity and connected the phone: "Hey? Didn't you just go? Caught that guy so quickly? ”

"Catch a ghost. What about Mu Zihan? "I don't know what happened, Lin Shixuan was obviously very impatient, as if he didn't have the heart to joke with me.

Seeing his tone and attitude, I knew that something big must have happened, so I also said seriously: "He is washing, it is inconvenient to answer the phone, what happened?" ”

"Let him stop washing, and he won't sleep after washing. I'll send you the address, you and him come over quickly, what's going on in the detention center. Lin Shixuan hurriedly finished speaking, hung up the phone, and after a while, a message was transmitted to Mu Zihan's mobile phone, the content of which was the location of the haunted detention center.

At this time, Mu Zihan also walked out with wet hair, looked at me and asked, "Lin Shixuan, what's the matter?" ”

"What the hell knows? He didn't say what happened, but he seemed to be in a hurry, saying that there was an accident at the detention center, and he wanted me and you to hurry over. I replied with a shrug.

Hearing my words, Mu Zihan's face sank, and he didn't care about his hair that was still dripping with water, so he put on his coat directly, and pulled me out in a hurry, and went straight to the position sent by Lin Shixuan.

On the way, I asked Mu Zihan suspiciously, why are you in such a hurry? Although, from Lin Shixuan's tone, I knew that this must be urgent, but there was no need to be in such a hurry, I had just washed my hair, so I had to dry it before leaving. After all, it's midnight in late autumn, and it's already very cold outside, and with wet hair, it's easy to catch a cold.

However, Mu Zihan's analysis and answer instantly raised my sense of urgency.

I saw Mu Zihan saying while driving: "From the content of the phone call you relayed, it is very simple to know that something must have happened in the office, and it is very likely to be related to the 6 members of the 'Butterfly' organization who were imprisoned there." ”

Then he gave me an analysis and explanation: The first point is that Lin Shixuan is usually a very stable person, and he will be so anxious, and the seriousness of the matter can be seen.

The second point is that it is close to 11 o'clock in the night, and at this time, he will not say a word and needs us to go over, which means that it must be related to us. And in that office, we are related to the six detained members of the "Butterfly" organization.

The third point, which is also the most urgent and complicated point of the situation, is that Lin Shixuan did not say anything on the phone. Obviously, the time is tight and the incident is complicated, and it is not something that can be explained in a few words on the phone.

Therefore, combined with the above three reasons, it is natural that Mu Zihan would rush to the detention center in such a hurry.
