Standing on the steps of the eleventh floor, Ling Xu was in a daze with a puzzled expression, he thought that the floor here was the same as the county hospital, and the floor number had also been changed, but after climbing from the first floor to the top floor, he didn't find anything abnormal, and the floor numbers were all correct.

Seeing that he didn't find any suspicion, Ling Xu was a little frustrated, turned around and wanted to go downstairs, but because he climbed up when he went upstairs, he climbed eleven floors in a row, Ling Xu's two legs were a little sore, and after taking two steps, he was really reluctant to take the stairs, so he turned around and walked to the elevator, pressed the elevator button, and then, the monitor prompted that the elevator was rising.

Just when the elevator came to the eleventh floor, when Ling Xu walked into the elevator, his mobile phone happened to ring, he took out his mobile phone and looked at it, and saw that the number was called by Shi Jinguang, Ling Xu pressed the answer button, and when the phone was just connected, the elevator door happened to close automatically, and then, the elevator began to descend slowly.

"Hey...... Old section chief, are you feeling better? Oh, it's so much better, I'm relieved, I heard Peng Brigade say that you are hospitalized, I was very worried, just now we went to the hospital together, but after arriving at the inpatient department, I suddenly thought of something important, so I came over first.

I couldn't go to the ward with Brigade Peng to see you, don't blame me. Now that I'm done here, I'm going to look at you, what? Immediate discharge? Oh, you don't want to be raised in the hospital, I think the hospital is stuffy, hehe...... Well, I'll visit you at home in two days. ”

The elevator just arrived on the first floor, Ling Xu also happened to hang up the phone, the elevator door automatically opened after the elevator arrived, seeing this, Ling Xu walked out of the elevator while loading the mobile phone in his pocket, when he closed the mobile phone, he inadvertently glimpsed the call time displayed on the mobile phone, only to see that the call time was 55 seconds.

At first, Ling Xu didn't care about this, but when he stepped out of the elevator, a flash of light suddenly flashed in his mind, and then, Ling Xu stopped and stood in place for a moment, and then, he turned to look at the elevator, and after thinking about it, Ling Xu got up and walked back, and returned to the elevator again.

Entering the elevator again, Ling Xu looked at the button on the elevator, found the "stopwatch timing" software from his mobile phone, and pressed the button on the eleventh floor, when the elevator door automatically closed, Ling Xu clicked on the stopwatch on his mobile phone, one second, two seconds, three seconds...... When the elevator rises to the eleventh floor, the door opens automatically, and the time displayed on the stopwatch is 55 seconds.

Seeing this, Ling Xu put away his mobile phone, a playful smile appeared on his face, and he silently recalled what Li Jinyong had said to him before, after Ling Xu and Li Jinyong lived in room 901, because he was afraid in his heart, Li Jinyong took advantage of Ling Xu's bath and wanted to sneak out quietly.

When the elevator rose to the ninth floor, Li Jinyong entered the elevator and pressed the button to the first floor, but instead of going down, the elevator continued to rise.

Li Jinyong glanced at the monitor from the elevator at that time, and found that the button on the tenth floor was actually on, and after about ten seconds, the elevator stopped from the tenth floor, because there was no one on the tenth floor, a few seconds later, the elevator door automatically closed and began to fall.

Because he was frightened by this strange thing and was afraid, Li Jinyong did not dare to go to the first floor again, but waited for the elevator to descend to the ninth floor, and walked down from the elevator.

The first suspicion, when people take the elevator, only when the elevator button is pressed from the inside, the button of the corresponding floor in the elevator will light up, if someone outside presses the elevator button, after the elevator reaches the floor, although it will automatically stop, but the button marked with the floor number in the elevator will not light up.

When Li Jinyong entered the elevator from the ninth floor, he found that the button on the tenth floor was lit from the inside, and after the elevator reached the tenth floor, there was not even a figure on the corridor, which is not at all reasonable, unless someone entered the elevator before Li Jinyong and pressed the button to the tenth floor, otherwise, the button in the elevator will not light up.

The second suspicion is that Ling Xu took the elevator from the eleventh floor to the first floor, and the time happened to be 55 seconds, and Ling Xu rose from the first floor to the eleventh floor, and the time was also 55 seconds, so if calculated, it is equal to every time the elevator descends or rises one floor, and the time used is 5 seconds, but Li Jinyong took the elevator from the ninth floor to the tenth floor before, but it took about 10 seconds, which also doesn't make sense.

With doubts, Ling Xu entered the elevator for the third time, he first carefully observed the inside of the elevator, pondered for a moment, and then pressed the button again, this time, he pressed not the button on the first floor, but the button on the tenth floor.

Ling Xu's idea was very simple, he wanted to take the elevator to inspect it layer by layer to see what secrets this elevator had? 10th, 9th, 8th, 7th floors...... The elevator descends one floor at a time.

When the elevator descends to the first floor, there is no problem, and the descending time of each floor is 5 seconds. In this regard, Ling Xu was a little unwilling, he started to rise from the first floor floor by floor, checking the lifting time and floor situation of the elevator, the first floor, the second floor, and the third floor......

After the elevator came to the eleventh floor, there was no problem, it was still 5 seconds per floor, neither fast nor slow, but because of this, Ling Xu felt more and more that there was a problem, because he believed Li Jinyong's words.

That night, Li Jinyong's fear of room 901 and the rumors of haunting, so Li Jinyong's mental attention that night was also highly concentrated in addition to tension, and in that case, Li Jinyong must have a clear idea of the time of the elevator.

In an environment of extreme suffering and resistance, the brain's calculation of time is often proportionally amplified, and it can perceive the passage of every second.

At that time, since Li Jinyong gave more than ten seconds, it must be accurate, but the problem is that it only takes 5 seconds to take the elevator from the ninth floor to the tenth floor, and it doesn't take 10 seconds at all, so what's going on with the remaining 5 seconds?

Scratching his head, Ling Xu's face was full of incomprehension: "It's strange, it's obviously 5 seconds, but Li Jinyong sat for 10 seconds that night, he took a first floor of the elevator, but it took him two floors to go up, why is this?" ”

Talking to himself, Ling Xu's eyes suddenly froze, and he thought secretly: "10 seconds? Two floors? Don't? Li Jinyong went up two floors that night? If this inference is correct, then Li Jinyong took the elevator from the ninth floor that night to the 10th floor not at all, but the 11th floor. ”

Thinking of this, Ling Xu hurriedly walked into the elevator to check, but here he has checked several times, and found no suspicious points, this time is the same, there is still no gain, the elevator from the 1st to the 11th floor of the floor buttons are complete, there are no changes and substitution symbols, except for the lack of monitoring probes, other elevator components are all here.

Take the elevator to the ninth floor, looking at room 901 next to him, Ling Xu frowned and pondered for a moment, then turned his eyes to the monitor at the elevator door, when the elevator descended to the first floor, he climbed the stairs to the eleventh floor, and after a little hesitation, he pressed the elevator button on the eleventh floor, and then, Ling Xu silently said "Stop", turned on the ability operation, and after the ability was running, he quickly ran back to the ninth floor.

Running to the elevator on the ninth floor, Ling Xu gasped for breath twice, and then lifted the ability, the moment the ability was lifted, Ling Xu pressed the elevator button on the ninth floor, and at this time, the monitor indicated that the elevator had begun to rise.

Forty seconds later, the elevator came to the ninth floor, the ladder door slowly opened, Ling Xu walked in, entered the elevator, Ling Xu began to calculate the time, and at the same time turned his head to the button in the elevator, it didn't matter, I saw a trace of shock on Ling Xu's face, it turned out that the button marked "10" in the elevator was actually lit at this time.

Nervous and excited, Ling Xu silently calculated the time, one, two, three, four, five, five seconds later, the elevator did not stop but continued to rise, and after five seconds of time passed again, the elevator stopped.

The ladder door slowly opened, Ling Xu's vision gradually revealed, when Ling Xu's eyes saw the scene outside the elevator, the expression on his face was a little complicated, only to see that at the entrance of the building opposite the elevator, there was a striking floor prompt number - 11F.
