The Book of Death by Heart Poison

The closing time of the boys’ dormitory in No. 10 Middle School is 20:9. After the evening self-study at 40:40, the students have 10 minutes to run at night and go to the cafeteria for extra meals.From the monitoring at the entrance of the dormitory, it can be seen that the peak flow of people is around [-] o'clock, and it decreases after that.

On the night of May 5, Zhang Ban consulted with Jia Bing until 2 o'clock. Based on the distance from the senior high school building to the boys' dormitory, if he had nothing else to do, the time when he appeared on the dormitory surveillance should be around 10:10.However, he didn't show up until the housekeeper closed the gate.

Liu Zhiqin dragged the progress bar to the next day, and found that at 8:21 in the morning, after the door of the dormitory opened, Zhang Ban entered with his schoolbag on his back.Before and after him, three other students from class 20 were captured by the camera, and all three of them did not return home at night.

"Have you checked the surveillance at several school gates?" Hua Chong asked, "Did they leave school, or did they stay on campus?"

Liu Zhiqin shook his head, "The management of the new campus is not yet systematic. Although there are cameras installed at the school gate, you can't just pass through the school gate if you want to enter and exit the campus."

When Hua Chongnian was in high school, flipping over the courtyard wall was like three meals a day, and immediately understood, "They can dig out."

"Yes. Moreover, the new campus covers a large area and has a long wall. It may take a long time to determine where they dug out from the traces." Liu Zhiqin said again: "If Zhang Ban and others are related to Jia Bing's disappearance , They probably left from near the west gate. There is a public surveillance outside the west gate, where Jia Bing was last photographed. I checked the video before and after, and there is no sign of any students.”

Hua Chong frowned deeply, "The coverage of that camera is too narrow, it's easy to avoid it."

Liu Zhiqin agreed, "I think the same as you. This group of students moved to the new campus in September last year, half a year is enough time for them to get acquainted with the surrounding environment."

In the last class of evening self-study, Class 20 of the second year of high school seemed to be pushed into the water by a pair of hands, and the silence was very depressing.

In the second grade of high school, there are six science experimental classes and two liberal arts experimental classes.In the eyes of the students in the ordinary class, everyone in the experimental class is a top student, and if you pick one at random, the score is above the line.But within the experimental class, there are also good and bad points. As far as science is concerned, class 17 is the best among the best, and five people in the top ten of each exam are from class 17.And class 20 is the "crane tail" in the experimental class. At most one person can squeeze into the top ten. In the exams that have been taken this semester, no one has been admitted to the top ten.

Due to their poor grades, the students at the bottom of class 20 are more likely to fall into the normal class than other experimental classes. Every time an exam comes, everyone is extremely nervous, for fear that one of them will not perform well and they will go to the normal class to hang out.

But at this time, the depression in class 20 is not because of the upcoming exam, but because of the disappearance of the math teacher Jia Bing.

This evening self-study is a physics evening self-study. The physics teacher handed out a set of papers. Zhang Ban stared at the papers. He didn't write for a long time, and his palms were already soaked in sweat.

"Are you unwell?" A short-haired girl at the same table bumped him with her arm, and put a pack of napkins on the table, "Your face is so red, don't you have a fever?"

Zhang Ban seemed to be frightened, a little taken aback, "No, I'm fine."

"You were like this before the last exam." The deskmate said, "Don't be nervous, you've made it through, as long as you perform normally, you won't fall."

Zhang Ban took the napkin like a ghost, and nodded.

His grades were not good, and he was always at the end of the exam, but he was lucky every time and was not transferred to the ordinary class.His deskmate comforted him, and he was grateful in his heart, but what he fears now is not the exam...

"Hey." The tablemate sighed, holding his cheeks, "What happened to Brother Bing, he couldn't have been killed like those teachers, right?"

Zhang Ban shuddered, his voice trembling: "Don't talk nonsense."

The deskmate whispered: "I also heard others say that. Think about it, those three teachers have been missing for so long. If they are still alive, how come there is no news at all?"

Zhang Ban's face turned pale, and it took him a long time to say: "Don't think about it, just do the problem."

That's what he said, but he just stared at the topic in a daze, and the draft paper was blank.

Footsteps came from outside the classroom, and Zhang Ban's heart constricted for no reason.

The physics teacher who had been sitting on the podium walked towards the door, and soon shouted: "Zhang Ban, Wang Xinyue, Sheng Qiang, Fu Jun, stop doing the questions and come out."

Zhang Ban looked out the door subconsciously, his pupils tightened suddenly.There were several men in police uniforms standing there. Although there was no one who looked for him in the afternoon, his heart was already beating violently.

When standing up from his seat, Zhang Ban turned around and looked at Fu Jun who was closest to him.Fu Jun glanced at him evasively, biting his lower lip nervously.

The criminal police from Chuanming City were waiting outside, and the four of them were taken to four classrooms. As soon as Zhang Ban entered, he saw Hua Chong, and his mind went blank.

"Sit first." Hua Chong pointed to the seat in front of him.

Zhang Ban stood like a wooden stake, looking at the ground with both eyes, "What's the matter with you? I'll talk about it this afternoon and make it clear."

Hua Chong said slowly: "Did you really make it clear? You didn't hide anything?"

Zhang Ban blinked quickly, and his facial muscles trembled frequently, "I have nothing to hide..."

Hua Chong opened the chair and sat down, watching Zhang Ban's eyes from below, "Last Friday night, after Teacher Jia finished explaining the questions to you, where did you go?"

Because of the constant swallowing, Zhang Ban's neck contracted several times, "I'm going back to the dormitory."

"Think about it again, did you go back to the dormitory, or where did you go?"

Zhang Ban seemed extremely nervous, "Where can I go? Of course I'm going back to the dormitory!"

"But the surveillance in the dormitory shows that you didn't return to the dormitory until the morning of May 5."

Zhang Ban opened his mouth in surprise.

"Student, you told an unwise lie." Hua Chong said with a serious expression, "Your roommate knows best whether you have returned to the dormitory. ?"

Zhang Ban was sweating profusely, "I, our school is closed for management, but that day was Friday, and there was no class the next day, so I wanted to go out and go out all night."

Although it is desolate outside the campus, there is a town after a short walk. The Internet cafe is open all night. It used to be a business for young villagers. Now students go to play games from time to time.

"Are you alone?" Hua Chong said, "Or with other students?"

Zhang Ban glanced wildly, "And Fu Jun and the others."

Hua Chong said: "Fu Jun, Wang Xinyue, Sheng Qiang?"

"Yes."

"Then how did you get out of school?"

Zhang Ban picked at his fingers, "Climb over the courtyard wall, the security guards didn't see us."

Hua Chong asked again: "Where is the courtyard wall?"

Zhang Ban suddenly stopped.

Hua Chong leaned forward, "Where is the courtyard wall?"

"To the right of Simon."

"But if you want to go to an Internet cafe, isn't it more convenient to climb over the wall near the south gate?"

Zhang Ban took a sharp breath.

"You went out from the courtyard wall near the west gate because Teacher Jia left through the west gate." Hua Chong said, "You want to follow him, right?"

Zhang Ban excitedly said: "No! How could I follow him!"

"In your competition exercise set, except for the page where you asked Mr. Jia, you have basically never done other questions." Hua Chong's gaze was like a nail, nailing the lying student firmly in place, "The evening self-study is so long, why are you so lazy? You have to wait until after the class bell rings before going to Teacher Jia. Your purpose is not to let him give you a lecture, but to hold him back. As long as you delay after 10 o'clock, he will not be able to get on the school bus and can only return to the teacher alone. Wind Garden."

Zhang Ban's eyes vibrated, he looked at Hua Chong in disbelief, and shook his head in vain and mechanically.

The trace inspectors from Haizi and Chuanming searched carefully along the walls on both sides of the west gate, and found four groups of messy footprints 120 meters to the right of the west gate. Some of these footprints have been destroyed, and some of them can distinguish shoe patterns. One of them is consistent with the shoe pattern of mud footprints in the alley, and both are new models released by a certain brand of sports shoes at the beginning of the year.

And Fu Jun's dormitory has a pair of sneakers of the same style.

"The shoe prints are the same, but whether they are the same pair or not can only be determined after modeling and analysis." Haizi said in the group channel: "But since we have found this step, it is impossible for such a coincidence to happen. I can say right now, it’s the same shoe.”

Compared with Zhang Ban, Fu Jun's attitude can be called domineering.

"Why do you interrogate me?" He is 1 meters tall, his hair is made of mousse, and he looks taller than he is. "I didn't break the law, so you just treat me as a suspect?"

Liu Zhiqin snorted coldly, "That's right, I know the suspect."

Fu Jun raised eyebrows, "You!"

"Last Friday night, why didn't you come home at night?" Liu Zhiqin asked.

"I have no obligation to tell you." Fu Jun said, "This is my privacy!"

Liu Zhiqin stared at the arrogant young man, "Don't open your mouth and keep it private, privacy is not how you use it."

Fu Jun was in a hurry, "Which bureau are you from? As long as I notify my dad, I won't have any good fruit for you!"

Liu Zhiqin's eyes turned cold again.

He has already found out the backgrounds of the four of them and their status in the class—Zhang Ban, who comes from a single-parent family, whose father is a migrant worker, with only an elderly grandmother at home. Wang Xinyue's parents are self-employed, engaged in catering business, and their income is not low. They also entered the second middle school, and their grades are slightly better than Zhang Ban's, but they are very unstable; Sheng Qiang, his father is unemployed, and his mother works in a small company. In administration, he is not rich, and his grades are comparable to Wang Xinyue's.

As for Fu Jun, he came from a wealthy family, his father was a well-known entrepreneur in Chuanming City, and he had contacts with various officials.Fu Jun did not do well in the senior high school entrance examination. He was admitted to the No. 20 Middle School relying on his father's face and the "sponsorship fee". It is reasonable to say that he could only enter the ordinary class. But when he was in the second grade last year, he was "sent" into the [-]th class. Ruan Shun became a member of the experimental class.

"At a young age, I learned how to bully others, even the police dared to threaten." Liu Zhiqin walked in front of Fu Jun, "Don't use your father to oppress me, I don't know who the one who has no good fruit is. "

Most of the time Liu Zhiqin appeared gentle and casual, but once he became serious, the aura exuding from his body was extremely compelling.

Fu Jun trembled without warning, and the arrogance disappeared immediately, "You..."

"I'll ask again." Liu Zhiqin said, "What did you do last Friday night?"

Fu Jun took a few steps on his hind legs, his eyelids trembling one after another, "Playing games, let's go to the Internet cafe in the town to play games."

Liu Zhiqin has already called the Internet cafe to monitor, "You leave school after 10 o'clock, and only go to play games at 3 o'clock in the middle of the night? Did you spend all the 5 hours on the road?"

"We, we..."

"You stopped Teacher Jia on the small road outside Shifeng Xiaoyuan."

Fu Jun's legs went limp, and he fell to the ground, staring in bewilderment, "I didn't!"

Liu Zhiqin looked down at him, "I found your footprints in the path."

Fu Jun yelled and put his head in his hands, "It's none of my business if he disappears! Whether he's dead or alive is none of my business!"

Liu Zhiqin said: "So you admitted that on the night of May 5, the four of you left school not to play games, but to target Teacher Jia?"

In four classrooms, four students successively explained what happened that day.It is impossible to piece together their testimony without being infuriating.

Entered the second year of high school, and got a new math teacher in Class 20. The previous math teacher was so strict that he was feared by the students. The new math teacher, Jia Bing, was a meek person. He was very young. He was said to have graduated Not long.

Although the students are young, they already have the awareness of distinguishing others, knowing that the old teachers can't be messed with, and the new ones can be bullied.

After a period of observation, Fu Jun found that Jia Bing seemed to have no life of his own besides teaching. Other teachers would definitely go back to the city on weekends. If Jia Bing missed the school bus, he would stay.

In the last exam, Fu Jun was only one point higher than the students who lost the ordinary class. This time he didn't think he had such good luck.

In fact, he didn't want to study in No. [-] Middle School, let alone squeeze into the experimental class, but it was about his father's face. When his father was happy, he could have whatever he wanted.So he must stay in the experimental class.

In the student group, it is often easier for the good students to become friends with the good students, and the poor students and the poor students report to the group to keep warm.After Fu Jun came to Class 20, he quickly became friends with Zhang Ban, Wang Xinyue, and Sheng Qiang who had similar grades as himself.Last semester, Wang Xinyue and Sheng Qiang both dropped to the ordinary class, and then rose back one after another.Every time they come to the exam, the four of them are terrified.

On the weekend half a month ago, Fu Jun invited the three of them to have a meal in the town, and proposed a plan - to kidnap Jia Bing.

"Jia Bing is timid and has no temper. He doesn't dare to do anything to us." Fu Jun said: "I have already found out that the math paper for the next exam is written by him, and the math will get more points. As long as we force him to reveal Big question, the ranking is stable."

Zhang Ban was worried, "But what if he messed up? If he tells the grade director, we will definitely be punished."

"Impossible, he doesn't have the guts." Fu Jun was confident, "And will anyone have trouble with money?"

Wang Xinyue asked: "Where do we do it? School?"

"You are stupid, how can it be a school?" Fu Jun said: "There is a broken factory near this town. Torture him slowly."

Zhang Ban was unwilling to join the group, "Torture? But he is a teacher after all."

Fu Jun slapped Zhang Ban on the back of the head, "You can't do great things if you are timid, do you still want others to underestimate you?"

Sheng Qiang was the strongest of the four, and he hugged Zhang Ban half-jokingly, "Brother, you have heard so much, is it possible to withdraw? Brother Jun and I will not agree."

The four quickly drew up a plan.Since most of the teachers would return to the city on Friday night, if Jia Bing couldn't catch the school bus, they would be left alone, so Fu Jun decided to implement the plan after self-study on Friday night.Zhang Ban is the most like a good student, and the task of holding Jia Bing is left to Zhang Ban.

Before Friday, Sheng Qiang accidentally discovered that Jia Bing had caught a cold, so he took advantage of the big recess to replace the capsules Jia Bing was taking with sleeping pills.

Everything went very smoothly. Jia Bing, who missed the school bus, walked into the alley in a daze, and fell into the trap of Fu Jun and others.

"What are you doing here?" Jia Bing had a splitting headache, his eyelids could hardly be opened, and four figures were moving back and forth in front of his eyes.

"Bingge, don't go back tonight, go somewhere with us." Fu Jun suddenly took out a pocket knife from his bag, and gestured in front of Jia Bing.

Jia Bing was exhausted and couldn't resist at all. He couldn't struggle, but was carried by Sheng Qiang and taken to the abandoned factory building.

When he was thrown on the ground, Jia Bing almost passed out. Fu Jun imitated the appearance of the gang leader on TV, and slapped him on the face, "Brother Bing, you made up the papers for the monthly exam, right? You must remember the big questions, write Come down, and I'll let you go back."

Jia Bing frowned, weakly, "Impossible."

"Tsk." Fu Jun laughed, "Bingge, I advise you not to toast or eat fine wine. If I dare to bring you here today, I must get the test questions. If you want to go back healthy, you need to get acquainted. Don't make me unhappy."

Jia Bing wanted to touch the phone, but Sheng Qiang took it away first.

Fu Jun gave Zhang Ban a wink, and Zhang Ban had no choice but to step forward, "Brother Bing, I'm sorry, just tell us, we really don't want to lose the regular class."

Jia Bing shook his head in disappointment, "You can't do this, I can't help you cheat."

Fu Jun's patience was limited, and he was furious, "Jia Bing, why are you so proud of yourself as a fresh graduate? Don't blame me for doing it if you don't silent the question today!"

Jia Bing refused to let go from the beginning to the end, and the two sides were in a stalemate until 2:[-] in the morning. Fu Jun and Sheng Qiang punched and kicked Jia Bing until he vomited blood and lost consciousness.

"Damn it!" Fu Jun scolded, "Why are you so stubborn!"

Zhang Ban panicked, "What should I do? He will definitely tell the director when he wakes up."

"Wake up and hit again!" Fu Jun said viciously, "I don't believe he would rather die than give questions!"

In the middle of the night, everyone was very tired, so Fu Jun proposed to go to the Internet cafe in the town to play games, and wait for Jia Bing to wake up.

Sheng Qiang was left to watch over Jia Bing, and the other three walked towards the town.Unexpectedly, Sheng Qiang called at dawn, saying that he just took a nap, and Jia Bing disappeared.

"What should I do?" Zhang Ban panicked beyond measure.

Fu Jun also panicked, and tried to calm down: "Going back to the dormitory, Jia Bing is alone, he has no recordings, no evidence, no matter what he says, we just kill him and deny it!"

The four returned to the dormitory, thinking that what was waiting for them was the livid face of the grade director, but at night, they waited for the news of Jia Bing's disappearance.
