The Book of Death by Heart Poison

"Teacher? Why did the teacher kill the teacher?" Hai Zi rushed back from the scene of throwing the body, and after hearing Liu and Hua's analysis from Pei Qing, he took a sip of tea.

After Pei Qing completed the autopsy, she took a shower, and not long after she changed into clean clothes, she was soiled by the oncoming tea, and she just wanted to kick Haizi away.

"I didn't do it on purpose either." Haizi hugged a pack of toilet paper and moaned as he wiped it for him, "If you want to blame, blame you for being too close to me."

Pei Qing patted his hand away, and said coldly: "You have been like this since you were a child, and you never know how to find reasons for your mistakes."

"Hey! What's the matter with you?" Haizi didn't want to wipe it anymore, he took out the paper and continued to drink his tea, "How old are you, and you can't always talk about your childhood, Teacher Pei, you Is it too big?"

Pei Qing pointed at the door, "Mr. Pei, who is not growing up, please get out."

After Haizi drank a cup of tea, he said seriously, "I don't."

Pei Qing: "..."

Some people may really be born thick-skinned.

"Old classmate, don't drive me away, give me fake wine, I'll use it to drown my sorrows." Hai Zi waved his hands.

Pei Qing glanced at him arrogantly, "Can you worry too?"

"Why not?" Haizi continued to wave, "Hurry up, bring Jiu Xin Tang!"

Pei Qing snorted coldly, "Stupid people usually don't worry."

Haizi's waving hands stopped, like a beckoning cat with no electricity.

"Damn! Why are you slandering your only lovely old classmate like this? Cut the nonsense, Jiuxintang!"

Many people in the special operations team smoke, including Hua Chong and Liu Zhiqin, so they are not addicted, but they always carry a pack with them.Pei Qing only had wine heart candy on her body, a hardcover box of seven, he could eat at most three by himself, and the other four had to be exploited by Haizi.

Hai Zi is worthy of being a trace inspector, no matter where he hides Jiu Xin Tang, he will find it eventually.

"You insulted the word 'cute'." Pei Qing said.

"Tsk." Haizi stopped talking and went directly to sneak attack. Sure enough, she found the last two wine heart candies in Pei Qing's coat pocket, peeled off the wrappers with satisfaction, and put them in her mouth.

"You are acting like a robber." Pei Qing said dissatisfied: "At least you have to kneel down and say thank you brother."

It is impossible for Haizi to kneel, but it is not impossible to say thanks, I saw him bow and open his mouth, "Thank you brother!"

Pei Qing wanted to kick someone again.

Haizi finished chewing the heart candy, but his sorrow was not overwhelmed. He sighed and said, "The murderer must have chosen Minggang Elementary School a long time ago. I stayed there for a day today and found that their management is so chaotic... so chaotic. Hold on to your toes! There is no surveillance. Although there are guard boxes, they are useless. Anyone who wants to enter the campus does not need to register. Half of the courtyard wall has collapsed and no one is watching. When no one is around, even in the daytime, the murderer may complete the dumping of the body."

"You are just worried that there are no footprints, fingerprints, images, or witnesses." Pei Qing fired a cannonball.

Haizi scratched his head, "These are all key clues, big brother, after a busy day and nothing, of course I'm worried."

"Not at all." Pei Qing took out another sugar candy like magic, "Once the murderer throws away the body, there will only be more and more clues. You have nothing to worry about."

Looking at the wine heart candy on the table, Haizi asked suspiciously, "This is for me?"

Pei Qing said: "Didn't you not water enough?"

Haizi was overjoyed, picked up the wine heart candy, "Cheers to our boat of friendship!"

Pei Qing said disdainfully: "The boat of friendship capsized 800 years ago."

It was already 1 o'clock in the morning when Hua Chong and Liu Zhiqin came to the vicinity of Minggang Primary School again.At this time, the traffic flow in the city center has already decreased, but the traffic flow outside Minggang Primary School has become denser.

A few years ago, Chuanming City issued a truck traffic management regulation, and trucks can only transport goods in the urban area between 0:6 am and [-]:[-] am.Minggang Primary School is next to the urban-rural junction in the west of the city, and there is a viaduct nearby. At night, the dust is flying.

Hua Chong pulled off his mask and turned his head sideways into the road.

A cement tanker truck passed by just now, and the dust billowed up like fog in a winter morning, making it hard to keep your eyes open.

"Come." Liu Zhiqin handed over a glasses case.

Hua Chong saw that there was a pair of optical goggles inside. Liu Zhiqin faced the computer for a long time in the information warfare team, and often put it on the bridge of his nose. After the criminal investigation team, he wore it less time.

"No need." Hua Chong shook his head, "It's not that dusty."

However, Liu Zhiqin took out the glasses directly, separated the legs of the glasses, and held them with both hands, "I'll wear them for you."

Hua Chong: "..."

Although in the relationship between the two, he is the older one, but in many cases, he has nothing to do with Liu Zhiqin.And maybe precisely because he is old, he occasionally thinks "macholy" that he has to give way to Liu Zhiqin, after all, he is the younger brother.As a result, Liu Zhiqin was spoiled by him and became more and more aggressive.

For example now.

When the criminal police went out to investigate the scene, they had never seen such a harsh environment.Chuanming City is a city after all, much better than those remote mountainous fishing villages.It's just a little sand and dust brought up by the truck. A mask is enough to cover it, so don't wear goggles.

But still complied with the sentence that Liu Zhiqin was spoiled, Hua Chong just said "no need", when Liu Zhiqin put the goggles on, he didn't even turn his head.

"Okay." Liu Zhiqin smiled, "Our flower team's eyes must be protected."

"Brother Xiaoliu doesn't need to protect his eyes?" Hua Chong said.

"Captain priority."

"Team members first."

"The captain has beautiful eyes."

"..."

The entrance of the elevated highway out of the city is about 1 kilometer away from Minggang Primary School. There are surveillance cameras on the main road, but there are many forks in this short 1 kilometer. Almost all of them are unpaved gravel roads. Rushed into a fork in the road, disappeared without a trace in the surveillance, Minggang Primary School is also on a fork in the road.

"The murderer is familiar with this area, so he will definitely not let his car appear on the main road. He drove from the side road to the vicinity of Minggang Primary School. As long as the timing is right, the vehicles passing behind can cover his wheel marks." Hua Chong came About 100 meters away from the damaged courtyard wall of Minggang Primary School, within a quarter of an hour, two medium-sized trucks roared past.

Liu Zhiqin said: "Use passing trucks to hide the traces. The murderer's car can only be parked here, no matter how close it is. For the last 100 meters, he needs to carry two corpses. Maybe the murderer has helpers."

"It can't be ruled out that there is a helper, but there is no one on duty at night in Minggang Primary School. It is not a problem to throw the body alone, but it is just two trips." Hua Chong looked in the other direction of the road. At this time, two bundles of cars The lights came from a distance, and another car was about to pass by.

"According to this frequency, when the murderer was carrying the corpse, there might be a car passing by." Hua Chong said: "The driver either saw the car parked on the side of the road, or saw him moving the corpse."

Liu Zhiqin said: "But no one would think that what is being transported is a corpse. If the car is captured by the driving recorder, it can be used as an important clue."

Hua Chong frowned, "No."

"Huh?" Liu Zhiqin turned around.

"Even if the murderer is familiar with this area, he can't guarantee that no vehicles will pass by when he stops to throw the body. The driver's witness is nothing, but what if it is captured by the driving recorder?" Hua Chong said: "He will really take the risk. Is the car parked here?"

"I suddenly had an idea." Liu Zhiqin rubbed his forehead, "We always thought that the murderer used transportation to throw the body, and ignored one point - the most dangerous place is the safest place."

Hua Chong said: "You mean, the murderer is related to Minggang Primary School? The corpse was also hidden in Minggang Primary School before?"

Liu Zhiqin walked towards the damaged courtyard wall, "The murderer is most likely a person related to the education industry. He used to or is still teaching at Minggang Primary School, which seems reasonable. But there is a problem in this way. Corpse, this is too bold."

Hua Chong was silent for a while, "Two ways of thinking can be investigated first. First, the vehicles passing by the main road last night, and second, the teaching staff of Minggang Primary School."

The criminal police of Chuanming City Bureau were on duty at Minggang Primary School. In the dark playground, high-power lights were turned on. Hua Chong greeted people and walked to the side of the sandpit, "Why was the victim made into a specimen? Brother Xiaoliu, you Got an idea?"

Liu Zhiqin turned his back to the light, and his shadow was stretched very long, "I think the murderer's choice of Minggang Primary School is the key. Among all the schools in Chuanming City, Minggang Primary School may be the most suitable place to throw the body. Conditions allow the murderer to leave us with the least traces. But he could have chosen a more suitable place."

Hua Chong nodded, "Not to mention anything else, just go to the west for about 2 kilometers, and the conditions for throwing corpses there are better than here."

"The murderer spotted the school, so he must throw the corpse at the school." Liu Zhiqin frowned half, "Because of the combination of school + corpse, he can express what he wants to express intuitively. He may have 'investigated' many schools, yes Most of the schools in Chuanming are well known, and after a comprehensive comparison, it is found that Minggang Primary School is the most suitable place to dump the body."

Liu Zhiqin paused, "I'm right, it's not just that this place allows him to avoid detection as much as possible."

Hua Chong happened to be standing in the shadow of Liu Zhiqin, half of his cheeks were brightly illuminated by strong light, and the other half was in deep shadows, "This is what I have been thinking about too. Before the bodies of Wang Yuxia and Zhang Xu were found, how did these four cases end?" Whether it is a serial murder case or an ordinary disappearance case, it is still impossible to draw a conclusion. One of the reasons is that the four missing persons have no similarities. We can only say that they have one thing in common, that is, they are all excellent teachers in the eyes of the public."

"Now that Wang Yuxia and Zhang Xu have been confirmed dead, it is a series of cases. The common ground we found at that time may be the real common ground." Hua Chong continued: "Minggang Primary School has poor teachers. The poor quality is not only the teaching quality. There is also the character of a teacher, throwing the body of an excellent teacher in the school where the disqualified teacher is, I always feel that this is the root cause of the murderer who wants to show the world."

Liu Zhiqin said: "Combined with this case, the specimen may represent a model, a perfect benchmark."

Both of them fell silent, obviously wanting to go together, but there are still many fogs that have not been cleared.

The most important thing is the motive of the murderer, killing excellent teachers, making them as crude specimens, and throwing them in a primary school with corrupt teachers. Is he targeting excellent teachers, disqualified teachers, or another group?

The next day, the investigation of Minggang Primary School and nearby roads was launched.

通过监控，警方发现，一共有27辆货车在凌晨3点14分到清晨6点之间经过明钢小学外的岔路，而在凌晨0点34分到3点14分这个时间段，则无车经过。

"This is a strange thing." Xu Xiaozhou stared at the video. "Actually, the traffic flow is the most dense between 12 o'clock and 3 o'clock. After 4 o'clock, there are fewer and fewer cars. No matter how many days we go forward, this is the rule."

"Then there is only one possibility." Liu Zhiqin stood behind Xu Xiaozhou, with his hands folded in front of his chest, "12:3 to [-]:[-] is the time for the murderer to throw the body. And his car, he set up a roadblock at one end of the fork in advance, and then removed the roadblock after he finished dumping the body."

Xu Xiaozhou quickly contacted 27 of the 10 truck drivers, and some of them provided driving records. Judging from the video, there were no suspicious vehicles outside Minggang Primary School.

"Here." Liu Zhiqin pointed to the display screen. "At 1:25, this truck had a tendency to turn a corner. It seemed that it wanted to enter a fork in the road, but when it saw something, it had to give up."

The truck driver worked at night and caught up on sleep during the day. When he was found, he kept yawning, "I didn't turn off the road, I kept driving on the straight road."

Seeing that he was in a trance, Xu Xiaozhou directly opened the video on his mobile phone, "Have you ever thought about the fork in Minggang Primary School?"

The driver looked at it for a long time, and finally said "oh", "I wanted to turn in at the time, and there was a shortcut there. I wanted to finish the delivery quickly and go home to sleep. But isn't that road blocked, so I won't let you in."

Xu Xiaozhou asked: "What do you use to block it?"

"It's the warning tape." The driver said, "Then how dare I enter it. It's the area around the school. I can't afford it if something happens."

"Imitation warning tapes can be bought online and offline." Hua Chong is inquiring some teachers at Minggang Elementary School and learned the investigation results from the road monitoring side. "Now we can confirm that the murderer drove over to dump the body." , and then use the trucks passing by to remove their own wheel marks. I still tend to think that the area between Jianshan Vocational High School and Nineteen Middle School is the murderer's daily activity range, and it is convenient to throw the body if you have a car."

Liu Zhiqin understood, "Didn't find anything at Minggang Primary School?"

Hua Chongdao: "Not yet, all the teaching buildings have been searched, and there is nothing suspicious. As for the teachers here, they are even worse than I imagined."

Liu Zhiqin: "Huh?"

"If you can suppress the students, you will use corporal punishment. If you can't suppress the students, you will let the students skip class." Hua Chong said: "The parents of the children who come to study here are almost all migrant workers, and they have no time and energy to worry about it. As for the school, I think it’s fine if the child can go to school.”

After a long investigation, almost all the teachers were terrified, and the teacher who let the students out to play during class time even cried in front of the criminal police.

"I beg of you, please protect me. I know I was wrong. I will be a good teacher in the future, and I will not do anything to offend my students."

After listening, Liu Zhiqin asked, "Why, those teachers think they are the murderer's next target?"

"Well. Teachers who have disappeared continuously for the past six months have already made the teachers panic." Hua Chong leaned on the wall of the corridor, "Many people are worried that they will be the next one. This time the body appeared in Minggang Primary School, and the society There are also rumors of the murderer's enemy on the Internet, and the teachers of Ming Gang feel that the murderer is killing the teacher with bad conduct, and they are the first to bear the brunt."

"However, the murderer killed a model teacher." Liu Zhiqin was in the city bureau at the moment, and after saying this, he caught a glimpse of a familiar figure from behind.

It is Hua Chong's father, Hua Linmao.

In fact, he and Hua Linmao have only met twice, not to the point of familiarity, but since he has something to do with Hua Chong, he instinctively takes his heart.

He could see that Hua Chong didn't care about Hua Linmao at all, it was just that his youthful experience left some shadows.He didn't intend to get involved in the affairs of the father and son, let alone be a peacemaker.His beloved did not get the care he deserved from his father when he was a child, and he hated Hua Linmao more than Hua Chong.

But obviously, Hua Chong did not make a clean break with his family, so he hoped that the shadow in Hua Chong's heart would become smaller and smaller, and it would be best if it could be eliminated.

After hanging up the phone, Liu Zhiqin walked towards Hua Linmao.

In the past few days, Hua Linmao would come to deliver food and soup every day, which was very rich, but because Hua Chong was busy, he only went to pick it up in person on the first night.

Liu Zhiqin observed for a while, only to find that Hua Linmao didn't just leave at the guard's place in the dormitory, but waited for more than ten, twenty, 10 minutes before going to the guard's place.

He really wanted to see Hua Chong.

Liu Zhiqin walked up, and Hua Linmao saw it at a glance, with a cramped smile on his face, "Aren't you busy today?"

It seems that the next sentence is: "Is Hua Chong here?"

Liu Zhiqin took the thermos over with a smile, "The flower team has gone to the scene, and I'm the only one in the game."

"That's good, that's good." Hua Linmao nodded, turned around and wanted to leave, then turned back after hesitating, "I heard that you found the body in the case you investigated?"

This is not a secret, it was spread all over the Internet yesterday, Liu Zhiqin said: "Yes, the flower team is over there now."

Hua Linmao hesitated and said, "Is there anything I can do to help?"

Liu Zhiqin was a little surprised, "You?"

"The ones who died were all teachers, and the ones who disappeared were also teachers. The murderer targeted the teacher, right? He probably hated the teacher." Hua Linmao's words actually represent the views of most Chuanming people, but what they don't know is that on the criminal side of the police In the novel, the murderer is also very likely to be the teacher.

"I am also a teacher. I have taught for most of my life. I may know the education situation in our city better than you as a policeman." Hua Linmao looked at Liu Zhiqin, hesitantly but firmly said: "What's the problem? You can ask me. I know Hua Chong is not good at talking to me, but I feel ashamed of him, since he came to Chuanming to handle the case this time, and the case is related to the teacher, I, I want to help him."

Liu Zhiqin thought about it for a moment, then said with a smile, "If you're not busy, come upstairs with me."
