Siqing also saw Zhao Bai'an and them, as if she originally wanted to walk in their direction, but she seemed to hesitate for a moment, glanced at them, and then squeezed her fist slightly, and then trotted towards them.

ran in only to find that it was Si Li, not Si Qing, no wonder he hesitated. The two sisters look too similar, and today Si Li didn't know why she tied up her hair and tied a ball on the back of her head.

It's no wonder that Zhao Bai'an made a mistake at the beginning, the long hair of the girl standing in front of her looked like a short-haired Siqing at first glance after her long hair was coiled up. ran closer, and Zhao Bai'an saw Si Li's bangs that were about to cover her eyes, and realized that she had made a mistake.

"Well..."Si Li stopped not far from Zhao Bai'an and the others. may be that she is relatively obedient, and because she is very unfamiliar with them, no, mainly Yang Zichen, Si Li looks a little nervous.

"Well, I'm looking for my sister." Si Li did not make eye contact with the two, but looked at Yang Zichen's knees.

"But I haven't found her for a long time...", her voice was still so small, "have you seen her......"

"Ahh I'm also looking for Siqing~" Yang Zichen took the initiative to get closer to Si Li, "Have you called her?" I tried several times and no one answered. ”

"Ahh Me too. Si Li weakly agreed.

Zhao Bai'an saw that there were some water stains on Si Li's cross-body schoolbag, and she squeezed the strap of the satchel nervously with her right hand, and her hand seemed to be a little wet.

"Oh, no one answered, did he? It's kind of weird. But the ball head is very suitable for you, it is a very refreshing feeling~" Yang Zichen praised Si Li, "I just looked around in the activity building of the drama club, but I didn't find Siqing, I'll look for it again with you~"

"Yes." Si Li nodded slightly.

Yang Zichen asked, "What places have you been looking for?" ”

"I wanted to come to the classroom to find my sister, but... She wasn't there in the classroom, so I went down to the second floor... It didn't turn out, so I wanted to go to your rehearsal place too. ”

"Uh-huh, I see." Yang Zichen thought for a while, "Then why don't we look for the first and third floors together, and then go home first if we still can't find it?" Maybe when you get home, you'll find that Siqing has already arrived~"

"Well...... Good. ”

The first floor was quickly found due to the relatively small number of classrooms.

"Oh, that's right." When she was going up the stairs, Yang Zichen seemed to think of something, and she suddenly said, "Si Li, have you checked the bathroom?" ”

"I've seen it on the second floor, but there's no one. I haven't seen the rest yet......" Si Li replied weakly.

"Good! Then check the bathroom on the first floor before going upstairs, maybe Siqing has diarrhea somewhere. ”

"Siqing~" Before entering the door of the bathroom, Yang Zichen began to call.

There was no response.

No door was locked, and the doors of the cubicle were still pushed open one by one to confirm that no one was in the bathroom except for the three people.

The three people in the bathroom on the second floor also searched again, but no one was there.

At this time, it has been more than half an hour since the bell rang after school, and the students in each classroom have basically left, and only three or two students who are cleaning are doing the final tidying work.

Come to the third floor.

Because it's a girls' school, it's all women's toilets along the way. This is the last restroom to be viewed by the trio.

"Siqing~" Yang Zichen called as usual. There is still no answer, no matter how you think it is, it won't be here.

However, as soon as he entered the door of the bathroom, Zhao Baian immediately noticed that the door of one of the cubicles was locked.

"Bang, bang, bang," The doors of the compartments were still quickly pushed open by Zi Chen, and when they checked the fourth room, they couldn't be pushed.

"Anyone? Is anyone in there? Yang Zichen knocked on the door.

"Sister?" Si Li also called out.

……

There was no response.

Although Zhao Baian knew that this was not good, it was a special situation now. She bent down and peered through the narrow gap between the cubicle door and the bathroom floor.

Two Legs......

Two feet in black leather shoes appeared in her field of vision.

Zhao Bai'an nodded at Yang Zichen.

"Hey! There is no one! After confirming that there was indeed someone inside, Yang Zichen slammed the door panel of the cubicle hard, "Siqing! Are you in there?! Why don't you speak? Are you okay!! Siqing!! ”

"Sister...... Sister! Si Li's voice began to panic.

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

The feeling of uneasiness is getting stronger.

"That...... Do you have coins? Si Li suddenly asked Yang Zichen.

"Huh? What's wrong? Yang Zichen asked as he continued to knock on the door.

"That...... If you use a coin, you may be able to open ......"

If you look closely, the doors to the cubicles in Ayton's restroom are all swivel rather than slotted. The oval black knob on the outside is connected to the swivel handle on the inside by a large slotted plastic screw. The thickness of the coin seems to be about the same as the thickness of this recessed line.

"I don't think I really have any coins." Yang Zichen instantly understood what Si Li meant, and fumbled in the pocket of her skirt, "There is no bag either." Yes! There is this! ”

She took out her student ID card from her cross-body bag, and although the thickness of the card was thinner than a coin, it could be used improvised.

The screws are slowly turned......

The door was pushed open.

"Thinking ......" Yang Zichen took a deep breath, but never heard her exhale, with an unbelievable look on her face, and her eyes couldn't be opened wider.

Si Li looked in, covering her mouth with her hands.

It was quiet and no one spoke.

There is only the sound of swallowing saliva, and the sound of a rapid heartbeat.

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

"Si Li...... Call an ambulance!!! Yang Zichen's hurried voice broke the silent depression filled with extreme uneasiness and panic.

"Hey, Siqing! Feed! She walked into the cubicle and tried to wake Siqing up.

"Sister!" Si Li's voice grew louder.

"Si Li, call an ambulance!" Yang Zichen interrupted Si Li and began to shake Siqing, who had begun to stiffen, "Hey Siqing!" Answer me! Are you still conscious? Siqing? ”

Zhao Bai'an squeezed into the small cubicle with Zi Chen, Siqing's hair was a little shiny, and she glanced at a small green bottle thrown in the trash can.

"PARAQUAT, 200 ML".

The bottle that was picked up by Zhao Bai'an was labeled like this.

"Zichen, it's useless." In order to be sure, Zhao Bai'an still reached out to probe Siqing's snort, and sure enough, he didn't feel anything, "Siqing is dead, and it looks like she has been dead for at least half an hour." ”

After all, it's already starting to stiffen.

"What...... What the? How so? Yang Zichen looked at Zhao Bai'an blankly, his mind was completely stagnant, "Si Li! Did the ambulance call? ”

"Zi Chen, you have to be calm..."Of course, Zhao Bai'an knew that she didn't say it when she said this, but she really didn't know how to comfort others correctly.

"Look." Zhao Bai'an held up the bottle with paraquat written on it to Yang Zichen, who was already sitting in the cubicle, "Paraquat, also known as the water of death, is a highly toxic pesticide that currently has no antidote. FOR AN ADULT, 5 TO 15ML OF 20% AQUEOUS SOLUTION CAN KILL PEOPLE, NOT TO MENTION THAT SIQING DRANK 200 ML. ”

"Do you know Zichen, it is often said that when paraquat comes out, the grass does not grow. Its lethality is too powerful, as long as you take it, you will inevitably die. ”

I can't help but sigh.

What's even more terrifying is that paraquat is not an instant poison that can kill people, and it will slowly corrode the internal organs throughout your body within a few hours of taking it. It gives you time to regret it, but it doesn't give you a chance to live.

Little by little, the mucous membranes of the mouth, throat, and esophagus begin to fester, and the lungs, kidneys, liver, heart, and adrenal glands slowly die, and you will feel more and more difficult to breathe, and your body will become weaker and weaker. Zhao Bai'an had no way of telling whether Siqing eventually died of organ failure or difficulty breathing. But it can be seen that she must have been very desperate at that time.

No, she's been desperate for a long time, paraquat isn't an easy poison to obtain. And during this period of taking poison, she can obviously regret it, although it is useless, but she does not.

In such a small space, facing the white door panel, feeling the passage of your life for a minute and a second, what a complete abandonment it is!

And what has I experienced, I am willing to endure such despair and want to escape, escape from my own life.

Zhao Bai'an didn't know.

Zhao Bai'an really didn't know why she wanted to die.

It's just that......

Zhao Bai'an squatted down and looked at eye level with Yang Zichen: "Zichen, I don't know why Siqing wants to die." ”

She hugged Yang Zichen, gently stroked Zichen's back and said, "But what I know is that she must be very happy." It's nice to have done everything you did for her at the last minute, you've been looking for her from just now to now. ”

Zhao Bai'an hugged Zichen tighter: "You looked for her, and found her, and didn't let her stay here alone for the night." Without your efforts, she might not be found until tomorrow morning, or even later. That's for sure, Siqing must be happy to have a friend like you.
