in the dawn

At this moment, there was a knock on the door, and a slender man was standing at the door. He wore a dark blue shirt and black suit pants, making him look rigid and simple.

Upon seeing this, Principal Wang immediately beckoned, with a little ease in his tone, "Teacher Sun, come in quickly."

"Officer, this is Mr. Sun, the head teacher of Class [-], Senior Three, Mr. Sun, this is the police officer here to investigate the case." Principal Wang introduced enthusiastically.

"Hello, I'm Sun Zehao."

This teacher Sun is the kind of person who would be reminiscent of a teacher if he guessed his occupation at first glance, with wide eyebrows and big eyes, a pair of square glasses, and a little bookish manner in his gestures.

Qiao Yuchuan looked at him silently. Generally, people who give people the feeling of being engaged in a certain kind of work, either have worked for several years, and the traces of the work have long been engraved on their body, showing it inadvertently, or it is deliberate. Dress up, through the first impression, deliberately create such a feeling.

Which kind would this Sun Zehao be?Is it natural or can be dressed up.

"Hello." Jiang Chengyun shook hands with him.

"I called Teacher Sun here because I wanted to know about Song Xiaoyang's situation at school."

Hearing this name, Sun Zehao showed a bit of bitter sadness on his face. He raised his hand and lifted his glasses to wipe his face, his eyes were flushed, and the exhaustion between his brows made him look very depressed, he looked really sad sad.

"This child is usually very well-behaved, and he is a very obedient child."

"Usually, she studies hard, is diligent, and rarely makes mistakes. The teachers speak highly of her."

"Then how is her usual relationship with her classmates?" Jiang Chengyun asked.

Sun Zehao pushed his glasses and sighed slightly, "Very good, she is still the class monitor, and the students all admire her."

"I never imagined that she would come to this point. How should I explain to the parents of my children?"

Having said that, Sun Zetao took off his glasses casually and threw them aside, covered his face, tears rolled down his face, and choked up crying intermittently.

Jiang Chengyun and Qiao Yuchuan looked at each other, and Qiao Yuchuan said slowly, "My condolences."

"Mr. Sun has been the homeroom teacher of Class One since the first year of high school. His main subject is mathematics, and his class performance has always been excellent. He is a star teacher in our school."

"He has a deep affection for this group of children, his classmates also like him very much, and his parents speak highly of him."

"What happened to Song Xiaoyang, Mr. Sun and I are very sad, we blame ourselves every day, and don't know what to do." Principal Wang explained Sun Zehao's appearance.

"I want to ask, whether Song Xiaoyang became the class monitor, whether she recommended herself or the class." Qiao Yuchuan asked.

Hearing this, Sun Zehao picked up the glasses that had been thrown aside, wiped his face with a piece of paper, his voice was still trembling, "It was selected by the class, that child is very obedient, although his grades are not the best, But it's the hardest working."

"So, the classmates all recommended her to be the class monitor, and she has been doing very well, without any major mistakes."

"Before her accident, did you notice any abnormal behavior of her." Jiang Chengyun asked.

"No, she has been very quiet and well-behaved, without any unusual behavior. Now I hope she showed some abnormalities at that time, so maybe I can find out early and stop it in time."

"I didn't do my best, it was my negligence, it was my fault." Sun Zehao said while weeping, as if he was really regretting and blaming himself.

Jiang Chengyun stared at him, and his eyes fell on Sun Zehao's raised hand, on which a Band-Aid was pasted, "Mr. Sun, did you hurt your hand?"

Sun Zehao looked at his palm, and there was a cartoon Band-Aid stuck on the side, with the cartoon image of Ultraman on it, and he unconsciously covered it with his hand, "Ah, I was bitten by the dog at home before going out this morning. "

"Usually I'm quite well-behaved, I don't know what happened this morning, but I suddenly took a bite." Sun Zehao said slowly, with a little helplessness in his expression.

"It seems that the injury is not serious. Just to be on the safe side, let's get a vaccine."

"Hey, good."

Coming out of the principal's office, Qiao Yuchuan and Jiang Chengyun walked side by side on the small road in the school. The surrounding tree branches have sprouted tender buds, and the flowers in the grass have also produced tender flower buds. As long as the sun is sufficient, they can enjoy themselves bloom their beauty.

"See what?"

"A child with poor grades is the monitor of the elite class, and the students are still very convinced."

"Judging from the actual situation of Ancheng High School, there are often two possibilities for this situation."

"One is that Song Xiaoyang's family status and conditions are superior enough, so she doesn't need outstanding achievements, she can also become the one among the stars. This is a bonus from external conditions."

"But obviously, the conditions of Song Xiaoyang's family do not meet this assumption."

Jiang Chengyun nodded, "What about the other one?"

"Another situation is that Song Xiaoyang himself is very sociable and resourceful, and can play with other children in his hands."

"But obviously this is also inconsistent, because Sun Zehao's evaluation of her is well-behaved and sensible, and judging from Sun Zehao's expression when he evaluated Song Xiaoyang, what he said should be true."

"But if Song Xiaoyang is a well-behaved and sensible child, then this is an obvious point of contradiction, which is not in line with common sense."

"I've said so much, what do you see?" After Qiao Yuchuan finished speaking, he put one hand in his pocket and tilted his head to ask.

Jiang Chengyun raised his hand to straighten the collar of his clothes, and his fingers cleverly avoided the scar on his neck, "This anti-theft net was installed three or four years ago, that is, this group of students just entered the first year of high school, and Principal Wang just came school time."

"Besides, you can't believe everything the two of them said today. There are still some things that need to be understood."

"But at present, I think the probability of homicide is [-]%."

Listening to Jiang Chengyun's words, Qiao Yuchuan kicked a stone casually, and watched the stone gradually roll away, his eyes became far-reaching, "Actually, the cases that happened on campus, compared with those brutal killings, are more serious. Even scarier."

Regarding this point, Jiang Chengyun also agrees very much. The campus should be an ivory tower far away from the world. It should be full of the simplest yearning, and it should be the place where evil should least be involved.

"So, we must find out the truth of this matter as soon as possible."

The two walked side by side and returned to the scene of the crime not long after.

Jiang Chengyun walked up the stairs to the rooftop, and Qiao Yuchuan followed behind him. The moment he stepped up, he saw a student standing under the tree opposite the teaching building from the corner of his eye, looking up with some embarrassment.

As if he noticed Qiao Yuchuan's gaze, he glanced at Qiao Yuchuan from the air, and immediately ran away in panic. Qiao Yuchuan squinted his eyes, and when he heard Jiang Chengyun calling him from upstairs, he turned and went upstairs.

Seeing the two coming, Su Bei immediately walked over, "Boss, Professor Qiao."

"How's it going."

Jiang Chengyun asked and looked around. The roof was very large, surrounded by railings, and only one railing was missing.

Su Bei followed Jiang Chengyun's gaze and said, "There is decay under the railing at that position."

"Preliminary judgment, Song Xiaoyang fell down with the railing because she was leaning on that position, and the decayed railing couldn't bear her weight."

"Besides that location, are the railings in other places also decayed?" Jiang Chengyun walked over to check the railing, looking at the broken gap, Jiang Chengyun squinted his eyes.

Su Bei shook his head slightly, "There are other locations too, but that location has the most serious damage. A sample has been taken just now and sent for inspection."

"In a place like the roof, the railings are naturally exposed. In the long run, damage is inevitable, but usually someone will be sent to check, go to the person in charge of the school, and check the roof maintenance records." Jiang Chengyun said and got up.

If the railings here are damaged naturally, that's all. If they are damaged by man, then things will become troublesome.

If artificial, in such a big campus, anyone could be a potential murderer, and everyone could become the next Song Xiaoyang.

Sun Ping left the scene of the crime with his head down. He walked in a panic, put his finger in his mouth and bit it, and it seemed that he was about to bite the skin, but he didn't realize it.

"Sun Ping, if you don't go back to class, where are you going?"

Unexpectedly, when he heard someone calling him, Sun Ping looked up subconsciously, and saw Sun Zehao standing opposite him with a stack of books in his arms, staring at him with a smile on his face.

At this moment, Sun Ping only felt a chill on his back, and his finger finally broke under his bite. The slight tingling pain brought him back to his senses, and he stumbled and said, "Sun, Teacher Sun."

Sun Zehao stepped forward, and Sun Ping subconsciously wanted to back away, but Sun Zehao stopped a step away from him, "Sun Ping, the bell is about to ring, hurry back to class."

Sun Ping lowered his head, nodded awkwardly, and immediately turned around and ran into the teaching building. Sun Zehao stood behind him, silently watching him run away.

The investigation lasted from early morning to afternoon. It was near evening that Jiang Chengyun drove Qiao Yuchuan away. The two found a small shop by the side of the road, ordered some food and brought them back to the bureau.

As soon as he entered the door, he saw a room full of people. Everyone was not off work and were busy sorting out the materials they got today. Jiang Chengyun put the bag on the table.

"Come and eat."

Hearing this, Feng Xue was the first to put down the things in her hands, rushed to open the bag, saw the food inside, her eyes glowed, "Wow, pickled fish and braised pork, boss, you are so kind."

"How can there be so much nonsense, eat quickly."

"After eating, everyone sort out the materials at hand, and have a morning meeting tomorrow morning."

"Yes." With the delicious meal, everyone swept away the fatigue just now, and instantly felt as if they had been beaten with chicken blood, and all of them had the confidence to fight until dawn.
