(October 2) countdown to the 89th day

The two of them turned back to the 17th floor from the 18th floor along the corridor one after the other, and the shoe that seemed to have fallen off Brother Niu was still lying in the corridor.

Rushing into the door with the same location as the three-bedroom upstairs, Xiao Feng was dumbfounded again!

The layout of the three-bedroom room is exactly the same as that of the three-bedroom room directly upstairs, and the position directly opposite the upstairs study is still set up as a study, but the bookshelves and desks in this study are completely different from the study they had just jumped from the upstairs hole, if they did jump from the upstairs study.

"Is this the study we just jumped into?" Xiao Feng turned his head and glanced at Liu Qing, who also looked surprised.

"No, I was the last one to jump down, and I checked every room deliberately, this study is definitely different from the one we jumped from." Liu Qing's tone was affirmative.

Xiao Feng found a wooden stick and pushed it hard at the approximate position of the chair upstairs a few times, and there were a few solid muffled sounds, and there was no sign of hollowing out the floor slab between the two floors.

How can it be?!

Xiao Feng was almost crazy, and he didn't believe that he had gone to the wrong room, but the room in front of him was obviously not what they had seen before! The two original rooms on the 17th and 18th floors seem to have disappeared suddenly!

"Impossible, impossible!" Xiao Feng walked back and forth in the room, talking to himself, and suddenly asked, "How long did it take between you running out of the door on the 17th floor and then returning to the stairs on the 17th and 18th floors?" ”

"It took about 1 minute to rush from the door on the 17th floor to the elevator; I was going down the stairs to the 15th floor, and I received you and asked me to return to the stairway between the 17th and 18th floors, about 1 and a half minutes; About 2 minutes back to the two-story stairwell; I received another time that you asked me to return to my room on the 18th floor, and it was about one and a half minutes later; Rushing back to the room on the 18th floor for half a minute, calculated as a total of no more than 6 minutes. Liu Qing said while estimating.

"Who has the ability to rearrange two three-bedroom apartments in less than six minutes? Is this gone? Xiao Fengyou shook his head.

"Team Xiao, there's a new situation! The person who found the suspected Niu Ge had just passed through the gate of the community. Inside the headset, a group of police officers who stayed at the gate of the community suddenly reported.

"Design a barricade ahead, arrest immediately!" Xiao Feng gave an order and rushed down.

Xiao Feng rushed downstairs, and on the way to the suspicious vehicle, he received a report that the suspect vehicle had been intercepted, and the man in the car was also wearing a pair of gold-rimmed glasses, but he was not Brother Niu.

More than 10 minutes ago, he received a call from a strange man, saying that there was a car in the garage that was about to be scrapped and he didn't want it, and asked him to drive away immediately, on the condition that he put on the glasses on the car and put on a jacket reserved for the seat. The man went to the designated parking space in the garage and sure enough, he found a car with an unlocked door. He was also curious, rich people are willful, and this car is far from being scrapped. didn't think much about it, and drove out of the community, "No, I was stopped by you." ”

After Xiao Feng arrived, he quickly understood that this was a trap for Brother Niu, and then turned back to the garage of the community and came to the parking space where the second-hand car dealer had just taken the car, and was puzzled.

There is no doubt that it was Brother Niu who called the man who resold the second-hand car, and it was Brother Niu who opened the car door for the man. The man dressed as Brother Niu drove the car out of the community in order to divert the attention of the police and create time and space for himself to escape. If the car door was opened by Brother Niu, then how did Brother Niu come to the underground garage? The elevator to the exit of the underground garage has already been guarded by police officers. Even if Brother Niu has the means to come to the garage without being discovered, then he doesn't have time to return to the 17th and 18th floors, and those two three-bedroom apartments mysteriously disappeared within 6 minutes, who did it?

It's hell.

But there are only tricks and no ghosts in this world, and there must be a fatal negligence somewhere. Xiao Feng thought as he walked, going up from the underground garage to the first floor.

The residents of the community have been disturbed and gathered in the atrium garden to discuss.

From 8 o'clock to now, the arrest operation has been almost 3 hours, and the police have found nothing. Looking at the more and more residents of the community gathered downstairs, Xiao Feng had to order the team to be closed.

Thinking that Brother Niu was once under his nose, no more than half a meter away, but he ran away, Xiao Feng felt extremely frustrated and blamed himself.

Reluctantly, he returned to his three-bedroom home on the 18th floor alone.

Sitting in this study that suddenly appeared like magic, Xiao Feng checked the floor under the chair again to confirm that it was intact, and checked the bottom of the desk again, and found no hidden mechanisms or anything like that.

He stumbled out of his room on the 18th floor and went downstairs to the 17th floor. The shoe in the doorway was still lying alone on the ground. Xiao Feng picked it up and compared the size, it should have been left by Brother Niu, it was speculated that Brother Niu fell from the hole on the 18th floor with a chair and ran away in a hurry. If Brother Niu ran in the direction of the staircase, how did he escape from the building surrounded by the police through the elevator or stairs?

Xiao Feng came to the study on the 17th floor, took out the stopwatch, pressed the timing button after a little preparation, sprinted outward with all his strength, passed through the bedroom to the living room, to the door, rushed out after opening the door, squatted down and took off a shoe and threw it in the corridor, without pausing and continued to rush to the elevator with all his strength, pressing the two elevator buttons respectively, and then stopping the stopwatch, showing the total time of 1 minute and 17 seconds.

He returned to his study on the 17th floor, timed again in the same way, and had a total of 28 seconds until he burst out of the room and could see the entire hallway. Then test from the door to the entrance of the corridor, and sprint with all your strength in 8 seconds.

Looking at the time of the three groups, Xiao Feng quickly deduced. Brother Niu had already calculated, and after falling into the study on the 17th floor with a chair, he should have rushed out of the room without any stops. The time it takes for me to hesitate and pause, plus the time it takes for me to get up from my chair and jump over my desk to the hole, is about 3 seconds; Jumping off the study on the 17th floor, stepping over the broken chair, through the bedroom to the living room, and glanced at the room layout slightly, to rush out of the room, there was a delay of about 3 to 4 seconds compared to Brother Niu. That is to say, with the same sprint speed, he rushed out of the room 6 to 7 seconds later than Brother Niu. These 6 to 7 seconds can reasonably explain that when he rushed out of the room, he didn't see Brother Niu in the corridor, because Brother Niu just had time to disappear from the corridor to the elevator.

There is only a time difference of 6 to 7 seconds between himself and Brother Niu, and when he arrives at the elevator entrance, an elevator goes up and down. This is a residential building, and there is no public space such as a pantry and toilet for Niu Ge to hide. He chased after him, and Brother Niu only had four ways to escape: taking the elevator up and down or walking up and down the floor.

So which one will he choose?
