"Xiao Liu, I'll go to their dormitory to remove a router later, and then you take it to the technical department to detect whether there is a recording playback and sensing device, and investigate the source by the way."

"Okay, Sister Wen."

"Chen Lin is responsible for verifying the places about the school in Cao Fang's novels to see if they are consistent."

"No problem."

"Xiao Zhe, Director Su sent me an information sheet of all the members of their class, and also marked the classmates who participated in the summer vacation, I will post it in the group later, and you will check one by one to find out the boy."

"Uh-huh."

"I've applied to the dormitory manager to stay with them tonight while I see if that weird knock on the door will happen again."

"After you complete the task, you can go back to rest, and then go back to school at noon tomorrow, are there any questions now?"

"Nope." The three of them replied in unison.

"Alright, disband."

After the tasks were distributed, everyone left the office.

Shen Panzhe wore a black mask, sitting on the steps of the flag-raising platform, where the lights were insufficient and a little dim, and in front of him was a vast football field, where many students gathered to sing and dance, so lively.

Seeing that he looked intently at the information of all the members of the painting class, he then clicked to add friends, entered the mobile phone number of the female class leader, and then applied to add friends.

After a few minutes, the other party agreed.

"Hello, Zhang Li, the female squad leader of the painting class, I am today's detective Shen Panzhe, is it convenient for you to come to the flag-raising platform now, I have something I want to ask you."

After Shen Panzhe finished typing, click send.

The other party immediately replied: Okay, please wait.

Ten minutes later, two girls came quickly from a distance, two with long hair fluttering, delicate faces, about one meter six or seven tall, dignified manners, wearing casual shoes, they were roommates, I didn't know that they thought they were sisters, they looked about the same.

Shen Panzhe didn't need to raise his hand to signal, because he was the only one sitting there on the flag-raising platform.

A moment later, they walked up to Shen Panzhe.

"Which of you is Zhang Li?"

"I am!"

Zhang Li raised her right hand and explained, "This is my roommate, Liang Liwen, she said that she wants to know you, and she also wants to add you to WeChat, I don't know if it's okay." ”

"Yes, yes, but I may not reply if you send a message, one is that I am very busy at work, and the other is that I rarely read WeChat except for work matters, so do you want to add?" Shen Panzhe politely refused, even if he added it, he would rarely chat or even reply.

"It's okay, if there's something, can I ask you for help?" Liang Liwen asked shyly.

"Yes, but I hope it's okay, because if something happens, it's a matter of human life."

"Uh-huh."

After adding Shen Panzhe's WeChat, she left happily.

"Don't stand, come, sit." Shen Panzhe said cordially, his tone gentle.

After Zhang Li sat down, she asked, "Officer Shen, you called me here, do you have something to ask?" ”

"Yes, then I asked, when you participated in the summer vacation, there were five boys, Jia Fan, Jin Peng, Zhao Fangbo, Chen Shengyong and Li Binyan."

"Among these five boys, who has these physical characteristics: slightly curly hair, melon seed face, thick eyebrows, very cold eyes, not very smiling, and moderate body shape."

After Zhang Li heard this, she thought for a moment and replied, "There are two people with slightly curly hair, Jin Peng and Li Binyan, whose eyes are cold and don't like to smile, then only Li Binyan." ”

"Does Li Binyan like to play basketball?"

"Yes." Zhang Li replied bluntly.

"I see, thank you for your cooperation."

"Officer Shen, you shouldn't suspect that it's Li Binyan, it's impossible, he's also the squad leader, although he is very ruthless, he often takes care of his classmates, especially for girls, there's no reason to play pranks on us."

"Besides, he can't get into the girls' dormitory, so how can he play a prank on us?"

Zhang Li defended him, and it could be seen that Li Binyan had a high reputation in the class and was very friendly, not like he could play tricks on people. But being said by her stimulated Shen Panzhe's curiosity even more.

Seeing that the corners of his mouth were slightly raised, he explained, "Zhang Li, you misunderstood, we don't just suspect him, but everyone else, and he is just one of them." ”

"Have you read a detective novel?"

Shen Panzhe asked with a smile, his eyes in the dim light, highlighting the profundity, which made people wonder through.

"I've seen a little."

"Then you should know Sherlock Holmes, right?"

"Acquaintance."

"Sherlock Holmes said: If all impossible conclusions are excluded, then the rest, however implausible, must be irrefutable facts."

After Zhang Li heard this, she was even more dazed.

"Haha, go back, Officer Guo will accompany you tonight, I wish you a good night's sleep."

"Uh-huh." Zhang Li stood up and thanked him, "Officer Shen has worked hard, goodbye." ”

"Goodbye."

After chatting, Zhang Li turned around and left, Shen Panzhe pondered for a moment, the first ruled out the ghost committing the crime, the second ruled out other professional revenge, and the third ruled out the spoof between them.

Then, there are only the boys in their class left, and Shen Panzhe and the others already have goals, so it is up to Xiao Liu to come over tomorrow with the answers to connect all the questions.

When the perpetrator is there, he will surface.

The moon and stars are scarce, and the night is quiet.

Two o'clock in the morning.

The lights on the five floors of Building B have been turned off, and the corridors are dim and empty, and there is no longer a figure.

Guo Wen stayed in B513, which is the dormitory of the squad leader Zhang Li, and the router of this dormitory has been taken by Xiao Liu to the technical department for testing, and the results will be available tomorrow.

At the same time, Guo Wen also specially reminded the other dormitories to unplug the network cable tonight to see if there would be a weird knock on the door.

Guo Wen looked at her watch, there was still half an hour before the knock on the door, if she didn't hear the knock again, it means that her guess was right, but it is also possible that the perpetrator did not dare to act rashly.

At this time, the girls in the dormitory all slept peacefully, after all, with Sister Wen's powerful aura suppression, I am afraid that no demons and monsters dare to approach.

There was still a minute left at half past two in the morning.

59… 58… 57… 56… 55…

7… 6… 5… 4… 3… 2… 1…

Guo Wen concentrated and stared ahead, and after two minutes, there was still no knock on the door, and she breathed a sigh of relief, it seemed that her guess was correct.

But......

Right the moment she lay down.

"Bang! Bang! Bang! ”

"Bang! Bang! Bang! ”

A crisp and loud knock sounded, intricate, disorganized, and incomparably real.

Guo Wen was stunned for a moment, how could this be possible, could it be that she guessed wrong, but half past two o'clock, why did it still ring, could it be that the perpetrator changed the time?

Perhaps there is another possibility......

"Impossible!"

Guo Wen immediately denied that it could not be a ghost.

At the same time, the girls in the dormitory were all woken up, seeing them get up in a hurry and stand with Guo Wen, this familiar voice could not be clearer to them, and their spirits were tormented every time it sounded.
