Si Qing also saw us, as if she originally wanted to walk in our direction, but she paused hesitantly, took a look at us, then squeezed a fist slightly, and then trot towards us.

When I ran in, I found out that it was Si Li, not Si Qing. No wonder she hesitated.The two of them looked so alike, and today, Silly didn't know why she twisted her hair up and tied a ball head behind her head.

No wonder I would admit it wrong at first. Her long hair looked like Siqing with short hair at first glance.When I ran closer, I saw her bangs, who was about to cover her eyes, and realized that I had admitted wrong.

"En..." Sili stopped not far from us.Maybe it was because she was relatively perverse, and coupled with us, no, mainly Zi Chen, but also very unfamiliar, Si Li looked a little nervous.

"Well, I want to find my sister..." Silly did not meet our eyes, but looked at Zi Chen's knee position, "But I haven't found her for a long time..." Her voice was still so small, " Have you seen her..."

"Ahhh! I'm also looking for Siqing~" Zi Chen took the initiative to move closer to Si Li."Have you called her? I tried several times and no one answered."

"Ah...Me too."

I saw some water stains on Si Li's messenger schoolbag. Her right hand squeezed the strap of the satchel tightly, and her hand seemed a little wet.

"Oh, no one answers, right? It's a bit weird. But the ball head is very suitable for you, very refreshing feeling~" Zichen Chaosili praised, "I just found a circle in the activity building of the drama club. , I didn’t find Siqing, I will look for it again with you~”

"Yep."

"Where have you looked?"

"I originally wanted to come to the classroom to find my sister, but... she was absent in the classroom, so I looked for the second floor... and nothing happened... so I wanted to go to the place where you rehearsed. ..."

"Yeah, I know." Zi Chen thought for a while, "Well, let's look for both the first and third floors together, and then go home if we still can't find it? Maybe we will get home. You will find that Siqing has arrived long ago~''

"OK."

Because there were fewer classrooms on the first floor, the search was quickly over.

"Hey, that's right." Zi Chen said suddenly when he was up the stairs, "Sili, have you checked the bathroom?"

"I've seen the one on the second floor, but there is no one. I haven't seen the others..."

"Okay! Then check the bathroom on the first floor before going upstairs. Maybe Siqing has diarrhea."

"Siqing~" Before entering the bathroom door, Zi Chen started calling.

There is no response.

No doors were locked, and the doors of the compartments were still pushed open to confirm that, naturally, no one was in the bathroom except us.

We also searched the bathroom on the second floor again, no one was there.

At this time, it has been more than half an hour since school is over. The students in every classroom are almost gone, only three or two cleaning students are doing the final finishing work.

Come to the third floor.

Because it's a girls' school, all the restrooms along the way are girls.This is the last restroom waiting for us to check.

"Siqing~" Zi Chen called as usual.There is still no answer, I won't be here anymore.

However, as soon as I entered the bathroom door, I immediately noticed that one of the compartment doors was locked.

"Pop, pop, pop," Zi Chen still pushed open the doors of the compartments quickly, and couldn't move them when they checked the fourth one.

"Is there anyone? Is anyone inside?" Zi Chen knocked on the door.

"sister?"

...

There is no response.

I know this is not good,

Two feet...

Two feet in black leather shoes appeared in my vision.

I nodded to Zi Chen.

"Hey! Is there anyone!" After confirming that there was someone inside, Zi Chen slammed the door of the compartment hard, "Siqing! Are you inside?! Why don't you speak? Are you alright!! Siqing!!!"

"Sister... Sister!"

The door frame was shaken by Zi Chen, but there was still no movement in the compartment.

The feeling of anxiety grew stronger.

"That... do you have any coins?" Si Li asked Zi Chen suddenly.

"En? What's the matter?" Zi Chen asked as he kept knocking on the door.

"That... if you use coins, maybe you can open..."

Take a closer look, the doors of the compartments in the Ayton restroom are all rotating rather than slotting.The outer oval black knob is connected to the inner rotary handle by a large flat-shaped plastic screw.The thickness of the coin seems to be about the same as the thickness of the recessed word.

"I don't seem to have a coin," Zi Chen understood Sili's meaning, and fumbled in her skirt pocket. "Neither in the bag. Ah! There is this!"

Zi Chen took out the student ID card from the diagonally across the school bag. Although the thickness of the card was thinner than that of a coin, it could also be useful.

The screw was turned slowly...

The door was pushed open.

"Thinking..." Zi Chen took a deep breath, but never heard her exhaling sound. There was an incredible expression on her face, and her eyes could no longer be opened.

Sili looked inward and covered her mouth with her hands.

It was quiet, and no one spoke.

Only the sound of swallowing saliva, and the rapid heartbeat.

The short-haired girl in the cubicle slumped on the toilet, with sunken eye sockets, excessively bulging cheekbones, and wide open mouth.

"Sili...Call an ambulance!!!" Zi Chen's hurried voice broke the silent depression filled with extreme anxiety and panic.

"Hey, Siqing! Hey!" Zi Chen walked into the cubicle, trying to wake up Siqing.

"sister!"

"Call an ambulance, Si Li!" Zi Chen shook Si Qing, who was already stiff, "Hey Si Qing! Answer me! Are you still conscious? Si Qing?"

I squeezed into the small compartment with Zi Chen. Siqing's hair was a little shiny, and Yu Guang glanced at the trash can and threw a small green bottle.

"Paraquat, 200ML".

This is the label on the bottle I picked up.

"Zi Chen, it's useless." In order to be sure, I reached out and probed Tan Siqing's breath. As expected, I didn't feel anything. "Siqing is dead, and it seems that he has been dead for at least half an hour." After all, the corpse has started to become stiff.

"Wh...what? How come?" Zi Chen looked at me blankly, his mind completely stopped, "Sili! Has an ambulance called yet!"

"Zi Chen, you have to calm down..." Of course, I know that I didn't say this, but I really don't know how to comfort others correctly.

"Look," I held the bottle with paraquat in front of Zi Chen, who was already sitting in the cubicle, "Paraquat, also known as water of death, is a highly toxic pesticide that has no antidote yet. . For an adult, a 20% aqueous solution of 5 to 15 ml can be fatal, not to mention Siqing drinking 200 ml.”

"You know, Zichen, it is often said that when paraquat is released, all herbs will not grow. Its lethality is too strong, as long as it is taken, it will not escape." People can't help but sigh.

What's more frightening is that paraquat is not a poison that can cause death immediately. It will slowly corrode the internal organs of your body within a few hours after you take it.It gives you time to regret, but it does not give you a chance to survive.

Bit by bit, the mucous membranes of the mouth, throat, and esophagus begin to ulcerate, and the lungs, kidneys, liver, heart, and adrenal glands will gradually become necrotic.I have no way of telling whether Siqing eventually died of organ failure or breathing difficulties.But it can be seen that she must be very desperate at the time.

No, she has been desperate for a very long time, after all, paraquat is not an easy poison.And during the period of taking poison, she could obviously regret it. Although it was useless, she did not.

In such a small space, facing the white door panel, feeling the passing of one's life every minute and every second, what kind of complete abandonment is this!

And what has been experienced, willing to endure such despair and want to escape, escape from his own life.

I do not know.

I really don't know why she wants to die.

just.

I squatted down and met with Zi Chen's sight. "Zi Chen, I don't know why Siqing wants to die." I hugged her, "but what I know is that she must be very happy. I'm glad you did it at the last moment. Everything she did, you have been looking for her since just now."

I hugged Zi Chen tighter, "You searched for her and found her. You didn't let her stay here alone for the night. Without your efforts, she might not be until tomorrow morning or even later. I was found out. I’m sure, Siqing, she must be very happy to have friends like you.”
