In fact, all kinds of efforts did not have a substantial effect, the incident began in the second month after the new students entered the school, that is, in October, after lasting for more than two months, winter came, and the pressure of exams also became greater, and after everyone went back to their homes during the winter vacation, no one mentioned it again at the beginning of the second half of the semester, and the legend about the mysterious girl disappeared by itself.

Mu Chun also heard him mention this story many times in Professor Chu's class later, and now he is standing in the security room, waiting for Zhang Hai and Liu Yiming to check the surveillance records, maybe he was touched by the scene and recalled the incident again.

Subsequently, Mu Chun asked Liu Dong in a strange way, is this dormitory building the same building that had an accident before?

Liu Dong shuddered for a moment, a trace of horror mixed with sadness in his eyes, he stared at Mu Chun's face, and asked incredulously, "How do you know about this?" ”

"It's no secret." Mu Chun said casually, as if this matter was an ordinary thing that everyone knew.

Liu Dong's face was still a little too nervous, Mu Chun guessed that it was either because it was too cold, there was no heating in the security room, and now the temperature here should only be between 3 degrees and 5 degrees, and it is normal for middle-aged and elderly people who are weaker to feel cold.

When a person is cold, it is understandable that the muscles on the face are a little tense.

Liu Dong sniffled, raised his right hand and rubbed it, and before he could think of how to respond to Mu Chun's words, he heard Liu Yiming say to Zhang Hai: "Found it, Zhou Gang." ”

Zhang Hai took a closer look at the monitor, although the picture was not very clear, but there was no one in the screen ten minutes before Zhou Gang appeared.

Liu Yiming let half of his body so that Mu Chun could also take a look, Mu Chun nodded and said, "Yes, it should be Zhou Gang." ”

The screen continued to play, and I saw Zhou Gang enter the school from the south gate, and then walked straight towards the path south of the third dormitory building, and then Zhang Hai rushed out of the third dormitory building, and then Liu Yiming also followed.

"Did this work?" Liu Dong asked, pointing to the picture.

"Yes, we need to make a copy of the information and bring it back, do you know how to operate the computer?"

Zhang Hai's tone has a majesty that can't tolerate Liu Dong saying no, Liu Yiming always says that he always said that it would be good if he could have Zhang Hai's momentum without anger and self-authority.

Zhang Hai told him that after a long time, it will naturally come about.

After the three of them exited the security room, Liu Dong sat down at the computer and began to export the monitoring records carefully and slowly according to Zhang Hai's requirements.

Zhang Hai sighed, and in the cold air of the morning, a white mist was rising from his mouth.

"Remember the time?" Zhang Hai asked.

"Yesterday I arrived here at about eight o'clock, and you can see that in the video, ten minutes after I arrived, that is, maybe at 8:15, there was no one in the surveillance during that time."

Liu Yiming was talking to himself and analyzed, while Zhang Hai took out a notebook and calculated the time when the three of them appeared here yesterday.

"Brother Zhang, judging from this monitoring, Zhou Gang came to the school after we arrived at the dormitory, which is too strange." Liu Yiming said.

The matter is actually very clear at this point, Mu Chundu has already seen it clearly, he thinks that Zhang Hai and Liu Yiming must also know very well that there must be some misunderstanding in this matter last night.

"Judging from the content of the surveillance records, it is impossible for Zhou Gang to appear in the bathroom before to peep at Deng Lin taking a bath." Zhang Hai said as he drew a line in his notebook.

Liu Yiming nodded in agreement, and then looked at Mu Chun.

"Doctor Mu, what do you think?"

"Unless he didn't enter the school through the south gate, but through other doors, and then hid in the girls' dormitory, it would logically work. After the bathroom peeping session was over, he still walked out of the school through another door of Sumikawa Medical College, and then returned to the school through the south gate, so that this is what we saw in the surveillance, and at eight o'clock, Zhou Gang appeared after Liu Yiming entered the school from the south gate.

Although it is a bit troublesome, if Zhou Gang deliberately wants to do this, it is not impossible, the difficulty is that the camera at the south gate can shoot the gate of the third dormitory building, and the location of the first camphor tree, he must not sneak into the dormitory building from the dormitory gate, if he wants to enter the dormitory building from somewhere else...... We should be able to see if it's feasible by checking it.

In addition, I don't know how many doors there are at Sumikawa Medical College to enter and exit the school, but judging from the monitoring position of the south gate, there must be monitoring at every gate entering and exiting the school, and it is not easy to avoid being photographed or seen by the security guards. ”

"Since you're here, let's check this dormitory building and see if there's any other way to go upstairs."

After Mu Chun finished speaking, Zhang Hai put the notebook in his pocket, and then proposed.

If you want to enter the dormitory building from outside the door, you can only climb into the dormitory window on the first floor, then enter the dormitory through the window, open the dormitory door and run to the second floor.

The school has obviously taken into account the safety of the dormitory on the first floor, and anti-theft windows are installed outside the windows on the north and south sides, and it is possible for a cat to climb in, and it is impossible for a person as big as Zhou Gang to squeeze into the dormitory through the anti-theft window.

"It seems that the voyeuristic thing is basically impossible to do."

After going around and returning to the dormitory door, Zhang Hai said.

"It may be Deng Lin's illusion, after all, I am alone in the dormitory, and it is winter, and the lights in this dormitory building are very dim at night, and it is not impossible for a girl to feel scared and call the police to say that someone is in the bathroom." After Liu Yiming finished speaking, he pushed Mu Chun and continued: "Doctor Mu, what do you think? Is this a possibility? ”

"Of course there is, the girl feels scared, and then she makes up a story in her head, yesterday her brain made up a story about someone peeping in the bathroom because of fear, this situation is also normal, but to the point of calling the police, it is a little exaggerated, but it is understandable. But there is one thing...... Deng Lin's proposal to ask the police to protect her is more interesting. ”

Mu Chun smiled, scratched her neck and added: "But this is nothing, maybe the girl is smarter and knows that she has the right to let the police protect her, so she asked for it, although ordinary people may not think of ......it."

"I don't think this Deng Lin is simple, if you peep at this matter because you are afraid to come up with it, forget it, I'm afraid that this matter will be her lying from beginning to end." Zhang Hai said sharply.

The cold air dispersed around him.
