Only a week later, on Friday, when all the boarders had to go home, Xie Yushuang took the position of class president, and when all the students left, he helped the teacher to clean up the class.

"Thank you, Yushuang, go home quickly, it's late."

Xie Yushuang looked at the No. 4 table, which had been empty for a day, suspiciously, and couldn't help but feel a little uneasy.

"Teacher, didn't Qianwen come to class today?"

"yes, she took a leave of absence, saying she had a stomachache." Teacher Wu smiled.

At this time, the crisp mobile phone rang, and Mr. Wu took out the mobile phone from his bag.

"Is Qianwen's mother? Hey, what's going on? ”

Li Qianwen her, she died.

Putting down the phone, Mr. Wu's eyes flashed with crystal tears, how could this be? Why did a student who was fine yesterday die because of a stomachache?

Xie Yushuang didn't believe in this reality, and decided to go to Qianwen's home to find out thoroughly.

Later, she learned about the general situation, after returning home that day, Qianwen said that she had a stomachache, and when she was a mother, she thought it was a monthly vacation, but she said that the monthly vacation was not so fast, her lips were purple, her skin was white, as if the blood all over her body had been drained, Li's mother panicked, so she sent the child to the hospital.

After more than an hour of first aid, the doctor wearing the white hexagram shook his head and said, let's prepare for the future!

The cause of death was preliminarily determined to be poisoning, which attracted the attention of leaders at all levels, because the students were boarding students, and the food was basically enjoyed in the school cafeteria, plus there was also a case of female student poisoning a month ago, and soon, the school cafeteria was checked thoroughly by the supervision agency transferred from above, but there were really no toxic chemicals found from the food in the canteen, besides, if there was a problem with the school canteen, why were there only two girls in the accident? Everyone else is okay?

Since Li Qianwen's death, table No. 4 has been empty, and no one dares to sit on it anymore.

Almost all the students stubbornly believe that table No. 4 is an unlucky place, maybe Ye Yanqin's ghost has not disappeared since his death, and he has come to this seat to hook his soul.

Of course, there are even more ridiculous claims.

Xie Yushuang didn't believe in any seductive theories, but there were so many students in the whole school, but the poisoned ones were all sitting at table 4 of class 11, which is too much of a coincidence, right? Superstition aside, there is only the possibility of a deliberate murder by someone.

But Li Qianwen has just been transferred from Tong'an No. 1 Middle School, and she has not been able to get along with anyone in the class, her popularity is very good, her parents are white-collar workers in a certain company, she is fair and fair, and she has no enemies! Who was going to put her to death?

There are many ways to kill a person, so why do you have to poison it? Who gave the poison? Where does poison come from?

All kinds of doubts are like the haze of Qianwen's death, which haunts her, so that she no longer has the heart to imitate all her energy to study, and she is familiar with the detective in the face of reality, but she seems a little powerless.

"Hey! Senior class leader, what do you think? Mengchen, a close friend, patted her on the shoulder, half-jokingly.

"Nothing," she said lightly.

"Nothing? Just now the teacher asked you to get up and answer the question, but you couldn't answer it, you weren't like this before, let's say, there must be something. She leaned over her sideburns with some cryptic husks, "Are you thinking about Qianwen's death?" ”

Xie Yushuang did not deny it.

"Actually, I'm also wondering, why did the two girls get poisoned like this? It's not ancient, and you can use a more advanced weapon to kill people, right? Well, such as machine guns, radiation bombs, etc. ”

"You also think they were poisoned artificially?"

"Of course, I don't believe that there are really ghosts in the world, and my boyfriend thinks so too, if you don't believe it, tomorrow!" She laughed and had two small dimples at the corners of her mouth, which was very charming, "I'll tell the teacher tomorrow that I'll sit at table No. 4." ”

Xie Yushuang was about to say something, but Mengchen had already run away.

This girl.

She smiled, but there was a faint weird feeling in her heart, she had this feeling before Qianwen's accident before, but now, this feeling is even stronger, shouldn't it?

After the fourth class, Mengchen really told Teacher Wu and asked to be transferred to table No. 4, why didn't Xie Yushuang know the idea of her little head?

Her boyfriend Chen Rongzhen sat at table 5, which made the distance even closer.

Tuesday morning, it was rainy and hazy.

Xie Yushuang bought it early and arrived at class early, the door of the classroom was open, maybe the last student who went out after self-study last night forgot to take the pass, right?

Before Mengchen came, she put two eggs on Mengchen's seat on the 4th.

It was about 7 o'clock later, and the students in the class arrived at the class one by one, and Mengchen was late.

Seeing two eggs and a bottle of mineral water on his table, Meng Chen glanced at her gratefully.

Xie Yushuang was drinking soy milk, so he asked, don't you have to drink something?

"I drink mineral water." Meng Chen blinked, picked up one of the eggs casually, peeled the shell and gnawed it, the yolk was pinched on his lips and he didn't wipe it, eating it like he hadn't eaten for several days.

Chen Rongzhen, who was sitting in the back, couldn't stand it anymore, I said you, can't you eat slowly? Don't be afraid of choking to death!

No, she replied, I am not afraid of anything, I am afraid of starvation, even if the egg is poisonous, I will eat it.

The last sentence unconsciously made Xie Yushuang feel frightened, he was about to say, Mengchen, you wait, but what appeared in front of him next was enough to make her so scared that she couldn't keep her mouth shut.

Mengchen, who was full of egg yolks, fell straight down like an elephant falling to the ground.

Fell right in front of her!

Her lips were purple, her hands were like white paper, and there was no blood, and her mother was a doctor, so she knew what this meant.

Mengchen, don't worry, I will definitely find out that murderer and avenge you!

When the school doctor arrived in a hurry, everything was too late, and the poisoning was too deep to be saved.

Xie Yushuang gently took Meng Chen's increasingly cold hand and put it on his face, trying to warm her up.

A few minutes ago, Xiao Chenzi, who was still alive, turned out to be a cold corpse a few minutes later!

The forensic doctor personally determined the cause of death, or poisoning!

So where does the poison come from?

According to the memories of his classmates, Mengchen only ate the same porridge mixed with salted fish as usual last night, because the poisoning did not last long, which means that there should be something wrong with this meal in the morning.

Xie Yushuang's face suddenly turned pale, those two eggs?

She was too worried, the forensic doctors used silver needles to test, and did not find any toxic substances on the eggs, so it is strange, she only eats two eggs for breakfast, besides, she slept so late, the food in the canteen has long been sold out, what else did she eat?

"Yes, water! She even drank water! Xie Yushuang pointed to the half bottle of water placed on the desk and said.

Mengchen has the habit of drinking boiled water, is allergic to soy milk, and likes to eat eggs with boiled water.

However, soon, the forensic doctors also tested the half bottle of water, and it was not poisonous.

How did the poison come about?

At this moment, another girl died of poisoning, and almost everyone was convinced that seat No. 4 was definitely an ominous seat.

Xie Yushuang noticed that Chen Rongzhen's complexion was a little abnormal, and she was sullen for several days, she was a little worried, if it went on like this, something would happen sooner or later.

She carefully recalled that the night before Mengchen's poisoning, the lights after evening self-study were turned off at 11 o'clock on time, and there was a surveillance video in the class, but nothing was found in the video, which means that the murderer was likely to take advantage of the black poison after the lights went out, how did the poison come about? Was it really accidental?

First Yan Qin a month ago, then Qianwen and Mengchen, one by one, as if it had been arranged, the murderer's purpose was by no means as simple as killing people, maybe he wanted to put everyone in a state of fear, what good would it do him like that? Maybe the truth is at table 4.

Yan Qin has been working at table No. 4 for nearly a year without any accidents, but she was poisoned more than a month ago, it seems that if you want to know the truth of the matter, you must start from her.

Xie Yushuang has been in the same class for nearly a year, and he only has a general understanding. I heard that her family is wealthy. Her hometown is in Tong'an, she can be regarded as a local, her parents work in a certain company, and she has a younger sister who is in junior high school. Xie Yushuang decided to find a breakthrough in this so-called sister.

After school that day, she didn't go directly to the cafeteria with her friends, but bypassed the big playground to the junior high school.

Yan Qin's sister Yan Ning's second and third classes of junior high school have already finished school, and the students came out of the classroom one after another, hurriedly asking, who is Yan Ning's classmate?

"I'm just, what's the matter with me?" It was a girl with a delicate ponytail who was not tall, but her skin was very white.

"I want to ask you something about your sister...... Hey, little classmate, don't run! ”

Yan Ning seemed to be very sensitive to this topic, and walked forward without looking back.

Xie Yushuang was unwilling and shouted in the back, but to no avail.

Could it be that there is something unspeakable?

Just when she was thinking about it, Yan Ning, who had already walked to the school gate, suddenly turned her head and said, If your curiosity is really that big, you can come with me!

She couldn't help but be overjoyed.

Yan Qin said that her sister didn't like the food in the cafeteria during her school days, and she often invited the two sisters to eat outside.

"Fortune teller?" She didn't feel a little big, how could it be related to superstition again.

"Yes, fortune teller.

Yan Ning went on to tell that my sister liked to go to the fortune teller from now on, and the fortune teller would also give my sister a medicine, and my sister would be very excited every time she finished eating, I was very worried, after all, I often heard adults say that medicine should not be eaten indiscriminately, no, I am sick after eating.

"In other words, your sister's poisoning was purely accidental." Xie Yushuang stopped, but saw Qin Ning shake his head.

"At first, I was suspicious of the fortune teller, but after my sister's accident, I checked the medicine my sister was taking, but it was just some brown sugar and other medicine packets, I tasted it, and nothing happened."

This is strange, since the medicine is fine, what is the problem? Why would Yan Qin believe what the Taoist priest said so much? Brown sugar, she knows that it is a symbol of marriage, that is to say, Yan Qin went to the Taoist priest to tell fortunes, it should be divination love or something, so if you want to understand why Yan Qin was poisoned, you must first find the answer from this Taoist priest!
