"Symbiotic relationship refers to two kinds of creatures living together and missing each other. Life will be greatly affected or even die." The biology teacher's voice was hoarse but loud, like the cicadas outside the window, and every sound was fulfilled.

The hot sunset entered the classroom and drew a line of light and darkness. Chen Nian sat on the dividing line between light and darkness. He was quiet and quiet.

The sun shrouded her hair on her forehead, golden, and she squinted her eyes, her eyelashes were black and long, and she futilely blocked the light.

A shadow came over. It was the head teacher, followed by two policemen.

The classroom suddenly became silent.

"Chen Nian," the head teacher stood at the door. The man who was always majestic was rarely kind and waved to her, "You come out."

Chen Nian looked at the two uniformed men and her face changed slightly.

She glanced at the empty seat in front of her, finally put down the automatic pencil, and when she got up, she pulled the school uniform skirt that was stuck to her legs.

The biology teacher and the whole class gave her a scruple. Her eyes were gone, and her ears followed her, and the hairs in the holes of her ears stood up, wanting to hear something fresh.

The head teacher patted Chen Nian's thin shoulders and comforted him: "Don't be nervous, I'll just ask you a few questions."

One policeman looked serious, the other was very young, and smiled at her gently, and there was dimples.

Chen Nian nodded and followed the head teacher to the office in silence. After walking a few steps, the head teacher looked back at the waiting students in the room and scolded: "Go to have a good class!"

When I arrived at the office, I sat down, and the air conditioner and air conditioner drilled into my pores like bugs.

The head teacher looked confident and looked at Chen Nian and asked, "Chen Nian, you should know why these two police officers came?"

"Know...know...know." Chen Nian has a problem with stuttering. He is not particularly nervous. His pale face is because he is naturally thin and thin.

"I know we fell from the building for Hu Xiaodie?"

Chen Nian nodded, staring at him with dark eyes.

"We don't ask others, come and ask you, do you know why?"

"I'm on duty that day."

"That day, Hu Xiaodie, you and two other classmates were on duty together. After cleaning, the two left first. When they left, only you and Hu Xiaodie were left in the classroom."

Chen Nian nodded.

"You said you left before Hu Xiaodie?"

Chen Nian nodded again.

"Did Hu Xiaodie reveal any information to you that day?"

Chen Nian shook his head, his eyes clearly black and white.

"Did you notice something strange about her?"

Still shake your head.

Another interrupted: "Can you tell us about Hu Xiaodie's condition when there were only two of you in the classroom that day?"

"It's all written in...the transcripts."

The head teacher interrupted: "This child has a really difficult conversation. I asked him once last time and all the recordings were recorded."

Chen Nian glanced at the class teacher quietly.

Chen Nian nodded.

A week ago, the security guards patroled and found a pool of blood on the floor tiles in front of the teaching building, and Hu Xiaodie's body was broken inside.

Hu Xiaodie is the school beauty, and she has the ugliest way of dying.

The police initially concluded that it was suicide, but the cause of suicide is still unclear.

There was no other problem, and the class teacher asked Chen Nian to go back to class.

Chen Nian walked out of the air-conditioned room and covered it with a layer of sweat, as if it was covered with a layer of plastic wrap.

She looked at the white sunshine, as if she saw Hu Xiaodie's milky white body, and a stream of air conditioning came up from the soles of her feet.

Cold and heat are mixed.

After walking a few steps, someone called her behind her: "Chen Nian."

It was the young police officer who handed her a business card. He smiled with a deep look, as if he could penetrate something: "My surname is Zheng. If you need help in the future, call me."

Chen Nianxin kowtowed and nodded.

Walking into the classroom was like pressing a mute button, a ballpoint pen, and the homework book was so quiet that it was spasm. Chen Nian seemed to be unknown, and walked towards her seat. There was a particularly sharp look in dozens of eyes, and she wanted to put a hole in her body.

Chen Nian glanced at Wei Lai sitting in the back row. The eyelinered eyes looked particularly deep, with a cold-blooded threat.

Chen Nian sat back on the chair. The classmate in front of him was slanted to snatch her legs under the table. Chen Nian reached out to touch her, touched a note from her hand, and said, "What are they asking you?"

Chen Nian was silent, looked at the empty seat in front of Hu Xiaodie, and then took his light to scan the people around him.

There was a sudden one missing person in the class, but everyone was not affected much. Only Hu Xiaodie's friend Zeng Hao cried from time to time.

Most of the others were talking, but more curious and puzzled than melancholy;

Or confused, life at the age of seventeen or eighteen is full of mystery.

A major characteristic and advantage of a teenager is that he is forgetful and can move forward easily.

The students who were whispering the other second before were quiet at this moment. Their eyes were hungry and lit up into dozens of light bulbs, staring at the wall clock on the wall above the blackboard—

The countdown to school is one minute!

No small words are allowed in class, but after school, it is like opening a bird cage. Students who usually do not abide by the rules transfer the countdown from their hearts to their mouths, and openly challenged the teacher: "20...19..."

Gradually, following the crowd, it was like a group of bees from far to near.

The biology teacher is very clear about the convergence of biology and the follow-up effect of ethnic groups, but he is helpless and unwilling to give up the textbook.

More and more students join the countdown: "13…12…"

Chen Nian's heart beat like a drumbeat. She had already put away her schoolbag under the desk and just waited for the bell to ring and rushed out of the classroom.

In the hot evening, sweat oozed from her nose.

The biology teacher asked without giving up: "What else does the interspecies relationship between organisms besides symbiosis, parasitics and competition?"

The whole class answered excitedly: "Preat!"

"prey!"

"Dingling~" The bell of get out of class detonates the classroom, noisy, tables and chairs colliding,

Chen Nian walked out of the classroom and was sure to walk out of sight. She ran, ran through the corridor, and bent into the stairwell. The white canvas shoes alternated on the stairs in almost panic.

Her calves are very thin, so she is afraid that she will break if she can't withstand this speed.

Several boys rushed past her roaringly. Chen Nian ignored it and ran hard, looking back from time to time, as if there was an evil ghost behind her that others could not see, asking for her life, and she was a prey to hunt.

After the bell ringtone after class, her white school uniform skirt disappeared at the school gate.

Chen Nian ran home all the way to the alley near his home. He was really exhausted and walked forward with his waist and gasping.

Her heart was like a drum beat. She wiped the sweat from her mouth and tightened the strap of her schoolbag.

The bluestone alley is shrouded in the sunset, like an oil painting, and the fragrance of greasy green pepper shreds floats out of the courtyard wall.

Pingping pong, it is a spatula that hits the iron pot, and punches and kicks.

A group of miscellaneous gangsters were beating people in the corner, and the boy in white T-shirt was curled up on the ground, without resisting or making any noise.

Chen Nian lowered her head and walked past the side with her breath.

The group of people cursed and sweared.

Chen Nianmu passed by quickly without looking sideways. He turned around and took out his cell phone, pressed two buttons, and the collar was grabbed by someone.

She was dragged into the crowd like a chicken.

He had to lower his head under the eaves, and Chen Nian's head was almost buried in his chest.

The little gangster patted her face twice: "Little bitch, who are you calling?"

Chen Nian drooped her eyelids: "I...my mother."

The other party grabbed her wrist and twisted it, and the number "11" was displayed on the screen.

"110?" He slapped the head, "Fuck. Your mother, I'm looking for death!"

Chen Nian fell on the white T-shirt, her cheeks were hot, and she regretted it. She shouldn't have been troublesome. It's all her business if she hurts someone and dies them.

"What JB thing!" The man was about to kick, and the other man waved his hand to stop him, squatted down, grabbed her ponytail and forced her to look up.

Chen Nian saw that the gangster was wearing a school uniform on his waist. He was her peers, but he was separated by an insurmountable gap, like a natural enemy, belonging to different species.

He raised his chin and pointed to the guy with a beaten white T-shirt: "Do you know him?"

He pulled Chen Nian's hair and frowned her head. Chen Nian hit a pair of dark eyebrows and eyes, hidden in the dusk, unable to see his emotions clearly.

"Don't recognize..." Chen Nian spoke a little hard, "I don't recognize him."

"Don't know?" The gangster held her chicken-like hair and shook her head, "Don't you know, you meddler?"

"I... don't care anymore." Chen Nian's voice was very small, with real regrets and weak begging for mercy.
