The two teenagers took the fat policeman nervously through the traffic, and stopped in front of the familiar residential building, Zhang Siyuan swallowed his saliva and pointed to the corridor: "He lives in 301." Pen "Fun" Pavilion www.biquge.info"

The fat policeman glanced at the two suspiciously, glared at them and said, "If I find out that I lied, you will be good-looking." ”

Zhang Siyuan and Wang Zhen laughed twice, stared at him apprehensively, raised his hand and knocked on the door, he shouted, "Hello, is it Mr. Cui?" ”

The three of them waited at the door for a long time and didn't wait for Teacher Cui to come over and open the door, Wang Zhen put his ear to the door and listened carefully, but there was no sound inside.

The fat policeman tentatively tapped the door a few more times, but after five minutes, there was still no movement inside. He was faintly angry, glared at the two of them, opened his mouth to scold something, but swallowed the words when they came to his mouth. He sighed, turned his head and ran downstairs without even looking at the two of them.

Zhang Siyuan shouted a few times at his back, and Wang Zhen stopped him and shook his head in frustration. Zhang Siyuan looked at the blue and black anti-theft door, kicked it violently, and was about to turn his head and leave, but the door suddenly opened quietly. Teacher Cui poked his head out like a ghost and stared at the two of them and said, "What are you doing here?" ”

Zhang Siyuan's scalp suddenly rose, and the blood in his whole body was frozen in an instant, and he didn't know whether to run or do anything. Wang Zhen took a few steps back and stammered: "No, it's okay, Zhang Siyuan said that he can't have a question." ”

Zhang Siyuan had no master of the six gods at this time, and he was about to make up nonsense with Wang Zhen's words, when Teacher Cui snorted coldly and slammed the door shut.

The two looked at each other, stunned and didn't know what to do. The door was suddenly opened again, and Mr. Cui's expressionless face came out from behind the door again, and he said coldly, "I know what you guys are thinking. You're completely wrong, I'm the prisoner. ”

The door slammed shut again, and Zhang Siyuan and Wang Zhen stood behind the door dumbfounded, completely confused by his words. What does it mean that I am the prisoner? Could it be that their thinking was wrong from the start? Zhang Siyuan's thoughts extended infinitely in his mind, and he suddenly touched a point that was silent in his mind...... He slapped his head suddenly, cold sweat broke out instantly, and he cried out in a lost voice: "Could it be like this? ”

Wang Zhen stared at him and asked eagerly, "What did you think of?" ”

Zhang Siyuan glanced at the door full of fear, only to feel that the chill had penetrated into the bone marrow, it was obviously a July day, but his teeth couldn't control the fight. He dragged Wang Zhen downstairs, and only when he rushed to the door of the community did he hold his stomach and stare at him fixedly, his eyes made Wang Zhen full of coldness. Zhang Siyuan said breathlessly: "I understand, the imprisoned person is Teacher Cui!" ”

Wang Zhen sighed, and Zhang Siyuan continued to say eagerly: "Do you know why our last expedition went so smoothly? Because that secret room, that secret passage is the escape route he set for himself! The key was placed on a somewhat high windowsill, which was half within reach of us. Mr. Cui's height is slightly taller than ours, and that height is just the height he can get by standing on tiptoe! ”

Wang Zhen's mind was as bright as a flash of lightning, and he couldn't help but curse, exclaiming: "The person who imprisoned him must be a short man, who could that person be?" ”

Zhang Siyuan shook his head and said with a pale face: "I don't know...... I've always wondered about these things, and I can't figure them out anyway. But it wasn't until I heard his words that I felt like a thunderbolt in my head, as if someone was holding a bamboo stick to string together these seemingly unrelated things. ”

Wang Zhen's face was solemn: "Then, should we ......go back?"

Zhang Siyuan's expression froze, and he looked a little embarrassed: "I don't know if we have the ability to save him, although the two of us are a little stronger than him, but what looks so thin that it can easily subdue an adult man......"

The two stood at the gate of the community for a long time, and people who came and went looked at the two teenagers strangely. After stomping their feet and scratching their heads countless times, they decided to go back and take a look, and if they found something wrong, they ran away desperately.

The boys wiped the sweat from their foreheads, climbed the stairs with heavy steps, and knocked tentatively on the door, but there was still no sound inside.

Wang Zhen imagined countless bloody pictures, his heart became more and more panicked, and he desperately took out the key from under the carpet and inserted it into the lock hole. Zhang Siyuan's heart was beating more intensely than ever, he wanted to stop Wang Zhen but didn't have the strength to raise his hand, he could only stare at him and turn the key, and the keyhole made a crisp sound.

The two of them walked in nervously calling Mr. Cui's name, and all the facilities and furniture in the room were piled up in place as usual, but Zhang Siyuan keenly felt that something was different here, as if something had left the room.

Wang Zhen held his breath and pushed open every door, bathroom, kitchen, bedroom...... Laundry was piled up in the corner, wet clothes were in the washing machine, and there were even cut broccoli on the cutting board. But there was no one else in the whole house but them, and the strange drawer under the table was pulled out and thrown aside.

The two of them walked back and forth in the room a few times, but they didn't even see a single figure. Zhang Siyuan looked at the half-human-high space of the black hole under the table, and cast an inquiring look at Wang Zhen. Wang Zhen frowned, grabbed a wolf-eye flashlight from the windowsill of the bedroom, and took out a kitchen knife from the kitchen and stuffed it to Zhang Siyuan. Zhang Siyuan stared at him for a long time, sighed silently, and then bent down and went in.

Because they had been here once, the two of them were familiar with the road this time, and after a few minutes, they had already climbed down the ladder to the ground. Zhang Siyuan looked around uneasily, and although Wang Zhen's hands were trembling, he still raised his flashlight to shine all over every corner. However, the dark room was more empty than the last time I came, and the pile of bricks blocking the doorway had disappeared somewhere, except for the plastic dummies wearing nothing, waiting for them in the corner.

Wang Zhen took him around the entire room back and forth twice, but found nothing. A hint of joy welled up in his heart, and his tense nerves relaxed a little. Zhang Siyuan put the kitchen knife aside, took out the key from Wang Zhen's pocket and inserted it into the lock hole, urging him to flee quickly.

This matter was hidden in the hearts of the two of them, and it seemed that they would complete a certain task by going around Mr. Cui's house, and they would be worthy of anyone - whether they found any traces or not. That afternoon, the two went to the basketball court of a nearby university to play basketball all afternoon, and then sat on the curb with sweat and dirty clothes, nibbling on popsicles and talking endlessly. The thrilling events of the morning never seemed to have happened.

Zhang Siyuan was very bored when he arrived at class again, but he was forced by Zhang's mother to pedal to a familiar place. It just so happened that Zhang's mother was on vacation on this day, and he was extremely reluctant to face Teacher Cui again alone, so he took Zhang's mother to go with him, and asked her to see his learning results.

Zhang's mother knocked politely on the door and shouted, "Is Mr. Cui here?" ”

Zhang Siyuan was a little apprehensive and a little embarrassed, hiding behind her and staring at the security door without blinking. But after a long time, the door didn't open, just like the day he and Wang Zhen went to visit. Zhang's mother muttered, and knocked a few times harder, but there was still no sound inside. Zhang's mother was a little puzzled, took out her mobile phone and called Teacher Cui, and put down her mobile phone with an ugly face in a few seconds: "Why did you turn it off?" ”

Zhang Siyuan's heart was shocked, he couldn't tell whether he was happy or worried, he lowered his head and asked Zhang's mother, "Then what should I do today?" ”

Zhang's mother looked annoyed, and secretly scolded Teacher Cui in her heart, but it was difficult to vent it in front of the child. She frowned and said, "Wait a little longer, maybe the teacher will come over in a while." ”

Zhang Siyuan replied sullenly, secretly praying in his heart that Mr. Cui would release his pigeons today and even next time. And things were really as he expected, the mother and son waited at the door for nearly half an hour without seeing Teacher Cui. Zhang's mother said angrily: "Go downstairs and go home." ”

Along the way, Zhang Siyuan felt that the garbage bins on the side of the road looked much more pleasing to the eye than usual, and although Zhang's mother sat in the back seat of the car, the bicycle felt a little lighter than usual. While thinking about what he was going to do in the afternoon to pass the time, he pedaled the car, and before he knew it, he was soon home.

Zhang's mother's mood was not as good as Zhang Siyuan's, she made more than ten calls to Mr. Cui at noon, but without exception, the other party was in a state of shutdown.

Zhang Siyuan never went to class again, and it wasn't until the evening of the fifth day that Zhang's mother rushed back with a blue face, and Zhang Siyuan realized that something was wrong. He was worried that his affairs would be exposed, and after careful questioning, he learned that Mr. Cui had evaporated from the world after noon that day, and his phone was always turned off when he called, and no one answered when he knocked on the door. Countless students and parents were furious, and some even asked a locksmith to pry open the door of his house, but it was empty, and the table was covered with a fine layer of dust - fortunately we blocked it with a drawer, Zhang Siyuan thought happily.

Zhang's mother was angry and distressed about the wasted money, and said angrily: "Some people say that he provoked someone who shouldn't be messed with, rolled up his belongings and ran away." Won't my money be wasted! I haven't had a few classes yet...... Alas! ”

After Zhang Siyuan comforted Zhang's mother for a few words, he secretly called to tell Wang Zhen the news. He pondered for a while and didn't say anything, just smiled: "Congratulations on getting out of the sea of suffering." ”

After that, Mr. Cui never appeared again for more than a month, and Zhang Siyuan lived extremely freely. Every day, I got up and went downstairs to buy breakfast and lunch, and after eating, I either read a novel or asked Wang Zhen to play ball or climb a mountain, and I didn't go home until the evening, take a shower, sit at the table and write homework for a while. In the test after the start of school, he scored more than 80 points for the first time, and Zhang's mother did not forget to scold Teacher Cui while feeling relieved. Zhang Siyuan listened to her voice, and only felt that the thrilling and bizarre days were extremely far away from him.

In mid-September, Zhang Siyuan unexpectedly received a thick envelope. He opened it in confusion and was pleasantly surprised to find that there were nine hundred yuan and a letter inside. He opened the letter in surprise, and the unfamiliar and somewhat familiar handwriting jumped on the paper:

Is life and learning still going well? I don't know if you still remember me, I'm Cui Zhengyi, Teacher Cui. Please forgive me for not saying goodbye, I am here to apologize to you, but I also have something difficult to say. I know you and another boy are always secretly investigating me, even sneaking into my house. But I think you must be confused now, I thought about it for a long time, and decided to tell you the truth about it.

I have a daughter with dwarfism, who is now nineteen years old and still the same height as a five or six-year-old child. This illness caused her temper to gradually become more and more eccentric and irritable, and her personality became withdrawn and autistic. The note that day was a joke she made with you to tease you, but she didn't expect you to be so bold to visit her. She likes to hide in the dark and not communicate with others, and I tried to correct it countless times to no avail, so I had to let her go. I used the money I had saved up to buy my downstairs house and transform it into what she liked. Did she make the strange villain on the table and my portrait, which can gradually disappear or highlight with the change of temperature - my daughter's personality is too weird, please don't care, the reason why I didn't say goodbye that time was also for her.

I have enclosed the cost of the tuition school and wish you all the best in your studies. Oh, by the way, you may still be wondering one thing, why do I have to go to the toilet every time I finish class? I'm sorry to tell you that I have some slight hemorrhoids.
