On the fourth floor of the 17th Teaching Building, there was a deathly silence!

Zhang Sicheng's eyes widened, watching a switchblade stabbed into his heart, a sharp pain, his vision began to blur, he looked at the other party's face, stretched out his hand and pointed at it from afar, his face was full of disbelief! With the last of his strength, he kept muttering, "Why...... Why ......" until the whole person collapsed to the ground, and there was no more sound!

At noon the next day, Lin Wenzhou walked out of the classroom after finishing the morning class, and he was somewhat surprised to see his girlfriend waiting for him at the door of the classroom.

An Zixin's expression today was a little strange, looking sullen, and he didn't have his usual flying at all, he couldn't help but walk over and ask Zixin what was wrong.

An Zixin pouted and said, "You know, last month my dad was going to be transferred to Shenjiang to work, serving as a member of the Standing Committee of the Shenjiang Municipal Party Committee and head of the Organization Department. He asked me last night if I would be interested in going to Shenjiang with him, and he arranged a place for me at CEIBS, where finance majors and American universities are in the alliance, and they have a good future prospect......

Lin Wenzhou immediately understood, and he smiled slightly: "Do you want to go?" ”

An Zixin flattened her mouth, nodded and said: "To be honest, I am a little tempted, I have always longed for that school, and the threshold for entering the school is very high, that is, after knowing that my father was going to serve as the main leader of the Shenjiang Municipal Party Committee, the principal specially approved a ...... for me in order to please him."

Lin Wenzhou said without hesitation: "Then you can go." ”

An Zixin glared at him, lowered her head and played with the corner of her clothes, and said a little twisted: "People are reluctant to ...... you"

Lin Wenzhou smiled bitterly: "Shenjiang to Qingzhou, the plane is only more than an hour, and it is not a parting of life and death, I can often come to see you." ”

An Zixin twisted him hard, and said angrily: "Hmph, I know!" You wish I was leaving, didn't you! As soon as I leave, you can fool around with your Senior Sister Ling in the open! Isn't it! ”

Lin Wenzhou said helplessly: "What the hell, I have nothing to do with Senior Sister Ling, you always think nonsense." ”

After a while, seeing that she was still very hesitant, Lin Wenzhou patted her on the shoulder and said, "Zixin, you don't have to give up so much for me." ”

As he was talking, Lin Wenzhou's phone suddenly rang, he glanced at the caller number, and smiled bitterly, the caller was Ling Shuanghua!

An Zixin knew what was going on as soon as she saw his expression, it was really a pot that couldn't be opened! I saw that the little girl was furious, and directly snatched someone's mobile phone, pressed the answer button, and said in a delicate tone: "Oh, Senior Sister Ling, what's the matter with finding my boyfriend?" We're going to have lunch together, why don't you come along......"

I don't know what Ling Shuanghua said on the other end of the phone, anyway, it didn't take long for An Zixin to say triumphantly: "Then Senior Sister Ling, Wenzhou and I continue to eat, you can enjoy it slowly by yourself......"

Lin Wenzhou broke out in a cold sweat, this girl changed her face too quickly......

After she hung up the phone, she was in a good mood, and she grabbed his arm with a smile and said, "Let's go, let's eat!" ”

Lin Wenzhou was very uneasy in her heart, she was in such a good mood, so there was only one possibility, that is, Ling Shuanghua on the other end of the phone should have been ruthlessly suppressed, with her arrogant surname, this revenge must be repaid with blood! God knows how it will erupt, and there's a good chance he's the innocent punching bag and victim, and he shuddeers a little at the thought of it......

The two didn't bother to get out of school, so they went directly to the eighth canteen to eat, An Zixin sat in her position proudly, and instructed Lin Wenzhou to run up and down the queue to eat.

An Zixin said with determination while eating: "I won't go to Shenjiang, I'll just stay here and watch you!" Hmph, she dares to call blatantly when I'm here, I'm leaving, you two are not **! ”

Lin Wenzhou hurriedly wanted to explain something, but at this time, suddenly his phone rang again, and it was Chen Jiayu who called, he was breathing heavily on the phone, and said with a hint of urgency and fear: "Wenzhou, it's not good!" ”

Lin Wenzhou said strangely: "What's wrong?" Such a panicked look......"

Chen Jiayu said nervously: "Zhang Sicheng is dead!" It was the boy who was in 414 the night before yesterday, and the aunt who swept the floor this morning found his body, lying on the fourth floor of the seventeenth teaching building! ”

Lin Wenzhou also exclaimed when he heard this, and his face changed greatly!

If it was just Gu Jiajia who disappeared before, he didn't pay too much attention to it, after all, missing and dead people are still two concepts, but now it has completely become a homicide! The surname is completely different!

Zhang Sicheng remembered the name, he was the only boy who was injured in the previous Gu Jiajia disappearance case! I remember that Jiang Xiaoxue mentioned his confession that day, saying that he was hit behind the head after rushing out of the classroom!

I remember that his transcript also mentioned that he seemed to see something abnormal......

Chen Jiayu's voice on the phone trembled a little: "Wenzhou, Ding Hui said...... That's the spread of legends...... She said we saw things that day that we shouldn't have seen...... So he got into the trouble of killing, maybe ...... Perhaps, the next one will be...... We! ”

Lin Wenzhou scolded angrily: "Jiayu, is it good for you to be a little more promising, what kind of legend is spreading, as a promising young man in the twenty-first century, do you still believe in this kind of thing?" Shame on you! That Zhang Sicheng's death may be just an accident, a coincidence! As for the last time, it was obvious that someone was playing a prank, pretending to be a ghost, and Sister Jiang and I already had some guesses! ”

Chen Jiayu said in a mournful tone: "Wenzhou, it's not a coincidence! Not a coincidence! There really are ghosts! I learned about the case, I heard that Zhang Sicheng died last night, and the forensic doctor judged that the time of death was after 10:30 p.m., but the probe at the corner of the stairs from the third floor to the fourth floor of the 17th teaching building last night was completely normal, and no one went downstairs after 10:30 at all! When the police arrived early this morning, except for the cleaning aunt who found the body, there was no one on the fourth floor! ”

Lin Wenzhou was also stunned, his head turned quickly, and he quickly understood the situation, this is a typical so-called secret room murder!

Because of the relationship between that probe and the husband, the entire fourth floor of the seventeenth teaching building after half past ten last night has completely become a secret room!

On the phone, Chen Jiayu was still screaming, obviously worried about his situation, Lin Wenzhou was speechless for his such timid performance, and could only comfort him: "Didn't Sister Jiang tell us clearly last time, their police did not disclose the fact that the four of us were also on the fourth floor that day, so you don't have to worry about ......"

Chen Jiayu leaned in and said with extreme fear: "Wenzhou, you still don't understand the situation!" Maybe no one knows...... But the problem is that we are not dealing with people! ”

Lin Wenzhou really couldn't stand this guy, and scolded angrily: "What is not a person, it's just that the case has not been solved, what are you anxious about!" With that, he hung up.

In the Public Security Bureau of the Haibin Division, Jiang Xiaoxue, the captain of the Criminal Investigation Brigade, frowned and said: "Captain Hua, Zhang Sicheng's body was found by the cleaners early in the morning, and the cause of death was that he was stabbed directly into the heart with a knife and died of excessive blood loss. ”

Sitting opposite Jiang Xiaoxue was a man in his thirties, named Hua Lei, whose position was the head of the criminal investigation detachment of the Qingzhou City Public Security Bureau, that is, the position of captain Xiong.

He nodded and motioned for Jiang Xiaoxue to continue.

"We checked the camera between the third and fourth floors, and just after ten o'clock last night, that is, after the lights of the seventeenth teaching building had just turned off, Zhang Sicheng went up to the fourth floor alone."

"No one has come up since then, which is understandable, after all, there has just been a disappearance here, and there are still terrifying legends among students about what kind of soul seducer, those college students and young couples don't dare to come here to make love."

Hua Lei gestured to her to stop, and then he was in a daze for a long time, recording something in his notebook, and then motioned Jiang Xiaoxue again to continue.

Jiang Xiaoxue continued with a serious face: "Our comrades have observed minute by minute, and no one has ever left the fourth floor from the stairs since then!" This is too strange, if no one else has gone up, it can be explained that the murderer stayed on the fourth floor before the lights went out, after all, there are normal classes there during the day, and there are a lot of people coming and going, so there is really no way to count, and then he waited until it was dark, until Zhang Sicheng went upstairs and killed him, but the question is how did he escape after that? When our police arrived at the school in the early morning, there was no one on the fourth floor! ”

Hua Lei vigorously extinguished the cigarette butt and said in a deep voice: "Have you carefully checked every detail on the fourth floor of that teaching building?" Are there any other entrances and exits? Maybe not so obvious, like throwing a rope from the window to climb down, like ......"

Jiang Xiaoxue shook her head and said with a serious face: "No! Our district bureau has investigated every inch of the fourth floor, the windows are one-piece sealed and cannot be opened, and the air windows above are so small that it is completely impossible to pass through a person. At the east and west ends of the corridor are walls and are sturdy. In addition, our comrades stepped on every inch of the floor, and there were no secret tunnels or anything like that. ”

Hua Lei stopped talking, and after a while, he said, "Could it be that the camera has moved?" ”

Jiang Xiaoxue shook her head silently and said softly: "I have also checked, there is no problem, and it is working normally all night." ”

Then she paused and said, "However, then again, that camera is actually not so clear, especially at night, it is inevitable that it will be a little confused...... But it's still clear whether there is anyone or not. ”

Hua Lei said in a hoarse voice: "In other words, it is indeed an invulnerable secret room?" ”

Jiang Xiaoxue's expression was also a little weird, and she didn't answer directly.

At this time, Hua Lei suddenly asked, "Xiao Jiang, do you have any questions in your heart?" You can say it. ”

It must be admitted that in the end, it is an old criminal policeman, Hua Lei is still very accurate in seeing people, Jiang Xiaoxue smiled slightly: "Indeed, I have a big question, and I have always been puzzled." ”

Hua Lei gestured for her to speak.

Jiang Xiaoxue brushed her hair and said word by word: "You said that in terms of universities, why do you want to install a probe between the third and fourth floors?" ”

There was silence in the conference room! (To be continued.) )
