Police Detective

There is also monitoring in this floor of the corridor, Bai Song can already habitually discover monitoring, this kind of ability also existed before, and ordinary people will also have it. But after the anti-tracking training taught by Master Qiao, Bai Song's ability in this area has been greatly enhanced, as long as it is not a very distant pinhole camera, he can easily spot it.

　　 The two quickly reached the door of the activity room, went in to find a table tennis table and looked at it.

　　 Here are two old men who are playing table tennis. You come and go with each other. They are very skilled and enjoyable. A dozen people gathered around to watch.

　　 The skill of smashing and catching the ball is so high that Bai Song is astounded. No wonder people say that the seniority of the community is good enough for the Warring States Period. But even so, there are still a few uncles on the side that said, "That's it." Each of these people is holding a beat and eager to try.

　　 Bai Song didn't understand these beats, so I chatted with Liu Shuyuan. Liu Shuyuan generally knows some high-end brands, such as Kaisting and Dakke. In short, one beat is basically Bai Song's one-month salary.

　　 Those who buy the racket prudently, they all buy one, not a pair. The uncles who come here are all local tyrants...

　　 Soon, an uncle was defeated, and someone immediately took over...

　　 The uncle who came down was a little frustrated. He put a guard on his beat and put it on the window sill. It seemed that he was a little tired.

　　 "Old Sun, you have won seven rounds, you are not reconciled!" Someone ridiculed.

　　 "It's no good if you don't accept the old, you can't keep up with your physical strength!" Hearing this, Lao Sun said happily.

　　 I can see that many people know each other, but these people have very good personalities, and they didn't pay much attention to Bai Song.

　　 If you are unfamiliar, it is a very polite behavior to not always stare at others.

　　 The two chatted for a while, and found a blind spot for monitoring. There was a chair to sit on here, and Bai Song just started to talk about the matter.

　　 "Do you remember, when you climbed the stairs last time, which floor was the laboratory on?" Bai Song asked.

　　 "I have no impression." Liu Shuyuan shook his head: "It should be on the tenth floor, right?"

　　 "Well, in my impression, but I always feel weird." Bai Song frowned.

　　 "Weird? Where is it?" Liu Shuyuan didn't feel anything wrong.

　　 "Don't you think that last time we went down to the sixth floor from the laboratory, it seemed that we only walked three floors?" Bai Song's complexion wrinkled deeper.

　　 "You mean, on the ninth floor?" Liu Shuyuan was a little confused.

　　 "No, in my impression, going down from the 13th floor to the laboratory is also on the third floor." Bai Song said: "But I didn't count, I'm not sure."

　　 "So gloomy, who counts this thing." Liu Shuyuan pointed to the outside: "Should we go and count it again?"

　　 "No, I always feel that there is a problem with this corridor. Let's walk rashly, and I don't know what will happen." Bai Song shook his head cautiously. The corridor was too dark, and he was unwilling to take meaningless adventures.

　　 "What do you do then?" Liu Shuyuan thought for a while: "I think you are still nervous. We didn't think about these things at all last time. How can you determine the number of layers?"

"But..." Bai Song bit his lip: "I just counted the time. It took about 9 seconds for the elevator to close the door from the seventh floor to the tenth floor. But it took about 9 seconds to open the door from the tenth floor. On the 13th floor, it took about 12 seconds."

　　 "Are you sure?" Liu Shuyuan exclaimed at Bai Song's strong psychological quality. In the situation just now, Liu Shuyuan's spirit was completely affected by the situation on the tenth floor. He didn't think about anything else, why would he consider counting such things? And why is this count?

　　 "The error is less than one second." Bai Song nodded.

　　 Liu Shuyuan was shocked by what Bai Song said, and on the other hand, he had a deeper understanding of Bai Song's "perversion". This is not a question of the ability to count and count seconds at all. Some people who speak a few seconds can have an error of less than one second within a minute, but in this environment, Bai Song also thinks about the matter of seconds by the way, which makes Liu Shuyuan a bit speechless.

　　 But it's not about this matter now. Liu Shuyuan now believes too much in Bai Song's words. He subconsciously began to consider what this matter means.

　　 Assuming that the elevator does not have the problem of variable speed at different floors, then, between the 6th and 13th floors, there is one missing! ! !

　　 "Impossible", Liu Shuyuan thought for a while, only to realize something was wrong: "From the outside, this building is indeed 13 floors!"

　　 "Of course it is the thirteenth floor. Eliminate all the impossibility." Bai Song pointed to the upper floor: "It is possible, there is another floor above this."

　　 Liu Shuyuan was stunned, he thought down, and felt that what Bai Song said could really be true!

Any building, fire exits and safety exits are required. Therefore, the downward corridor here is usually not sealed at 0. However, it is a routine operation for the hospital to seal the upper floor, and no one will ever go there. check. As long as there is no fire in the hospital, no one will ever ask to go to the rooftop for inspection.

　　 In addition, the hospital may still have a little backstage. If it is true that this floor is twelve and there is another floor above, it is normal that there is no relevant department to conduct door-to-door investigations.

　　Because the windows of the building cannot be opened and it is made of one-way glass, sometimes there is really no way to determine which floor is the top floor in the usual sense.

　　 This hospital is opposite the prison, and there are no high-rise buildings nearby, and it is also a no-fly zone for drones... This is really the 12th floor, and no one will ever find it.

　　 How many people will run to the number of floors in the gloomy corridor?

　　 Liu Shuyuan became a little excited, this kind of big discovery often means a big problem! The big questions are often very interesting!

Bai Song saw Liu Shuyuan look like this ~www.wuxiaspot.com~, but still said: "We have to withdraw. If there is such a big problem here, then we are really easy to be found out. Even if we are not in danger at that time, if they know about it, it will not be good to transfer or destroy the illegal and criminal things in advance."

　　 "Well, withdraw, look back and derive a face, and the old policeman will come over and investigate slowly." Liu Shuyuan agreed with Bai Song's statement.

　　 "It's not in a hurry, it's easy to say anything." Bai Song was still calm.

No one should pay attention to monitoring at this moment. The things downstairs have not been finished. If it is really as Bai Song estimated, this hospital has a big problem, then it is normal for the hospital to pay attention to the police. There are so many on the first floor. Police, it's normal to attract such a big attention.

　　 Bai Song is very good at making use of various environments, but now it is estimated that the downstairs has also slowed down. If you stay longer, it is easy to have problems. The two left directly and took another elevator downstairs.

　　 Now is the safest time, but next time, the two can never come again.
