"There were no wounds on the bodies of the two deceased, and there were no signs of poisoning in the preliminary judgment, and the exact cause of death needs to be further investigated.

Their bodies were found by a sanitation worker at the school, and it is described that their bodies were tightly hugged and then wrapped in chains around the swing, meaning that they were hung from the swing all night. ”

"Swing?" Hearing this description, Li Chenfeng felt more and more that the deaths of these two people were related to the thing he investigated last night.

"When did they die?"

"It's about half past two in the morning."

At this time, Li Chenfeng secretly said in his heart: Half past two, isn't that about the same time as when I left here last night, or was I killed as soon as I left them?

"This is the third murder case that has occurred in this school in recent times, involving a total of seven lives, and the upper authorities have already issued a death order, asking us to solve the case as soon as possible, Xiao Li, I know that you are very good at solving these bizarre things, so if you see something, I hope you can tell me truthfully."

"Of course, with our relationship, I can still hide it.

But just looking at the corpse and the scene, I can't see the reason for the time being. You just said that this is the third homicide, is there another one besides last night's accident and the previous one? ”

"Well, because that case involved a lot of elements to solve the case, it was not broadcast by the media."

"Tell me about it."

"The two deceased are also a man and a woman, both students in the third and second classes of this school, they were killed half a month ago, and the cause of death was gas poisoning."

"Gas poisoning?"

"That's right, although the deceased were both high school students, they had an abnormal relationship between men and women, they did not live in the school's dormitory, but rented a house outside the school in violation of the school's rules, and the two have been living together.

They were supposed to be sleeping at the time of the crime, and then they didn't notice the gas leaking in the house. ”

"In other words, the seven victims are all students, and they are all classmates?"

"No, these seven victims belong to different classes, but according to the investigation, the relationship between the seven of them is very good, and they usually get together to play."

Li Chenfeng nodded. "Okay, I think I've learned enough, if I have any clue about this case, I will notify you as soon as possible, I won't bother you police handling the case, let's go first."

"Okay Xiao Li, remember to drink together when you have time."

"No problem."

That night, Li Chenfeng originally planned to go to the school sports field again, but because the place was still sealed by the police, he might get into unnecessary trouble if he rushed in at this time. After all, Li Chenfeng was the last person the two high school students saw before they died, and he was lucky that he was not convicted of murder.

In the afternoon of the next day, the school resumed normal classes, and Li Chenfeng was going to wait for his niece Chen Wenwen at the school gate according to the reservation with Zhang Selling Dog.

The end of school was half past five, and Li Chenfeng arrived at the school gate at almost five o'clock, and he was still thinking about how to communicate with Chen Wenwen, but then he saw a familiar figure walking over across the street.

Zhang sold dog and bought something at a roadside stall outside the school, and then walked towards Li Chenfeng with a smile.

"Brother Xiao Li, it's quite early."

"Well, didn't you let me come alone to see your niece's daughter, why did you come too?"

"Wasn't I afraid that you wouldn't come again, so I came here to take a look."

"Heh, you don't trust me like that."

"Where."

Li Chenfeng glanced at Zhang Gou's hand. "I said what you bought, it's not dark."

"Stinky tofu, Wenwen likes to eat this very much."

"I can't see it, your uncle is quite competent, and I feel that I love her more than her parents."

Zhang Sellgou sighed. "What's the way, I'm just such a relative when I sell dogs, and her mother doesn't like to take care of me, and now Wenwen still recognizes me as an uncle, I don't care who she hurts...... Alas, they were out of school. ”

As soon as the school gate opened, the students inside walked out one after another, but Li Chenfeng and Zhang Maigou looked at the door for a long time, and they didn't see Chen Wenwen come out.

After about twenty minutes, the students had basically finished, and Li Chenfeng said impatiently: "Will that girl skip class today and not go to school?" ”

Zhang Maigou said very unhappily: "Impossible, my Wenwen is a good student, how can she skip class." ”

"Heh, who said that good students won't skip class......"

As she was talking, a girl in a school uniform and a skirt walked out with a shoulder bag on her back, she was half-bowing her head, and there was no one else around, looking a little lonely.

"Look, Wenwen can't come out."

Seeing that his niece came out, Zhang Sellgou hurriedly walked up with a smile.

"Wenwen, it's time for school, come, this is the stinky tofu that my uncle bought for you."

"Uncle."

Wenwen shouted so casually, then took the things in Zhang Gou's hand and continued to walk forward, without even raising her head during the whole process.

Although her attitude was cold, Zhang Meigou didn't care at all, and kept shushing with a smile on her face, asking her how she was doing at school today and whether anyone bullied her.

Zhang Maigou followed Wenwen forward and beckoned to Li Chenfeng, and Li Chenfeng also followed.

"Wenwen, this person is your Uncle Li, he is my uncle's best friend, if you have any trouble, just tell Uncle Li, he will definitely be able to help you solve it."

Li Chenfeng didn't know how to communicate with this kind of young girl, so he had to say hello with a smile.

"Wenwen, hello."

The girl seemed to be deaf to what she said to them, and still walked on her own.

Li Chenfeng stopped his steps and said to Zhang Sellgou: "I said that your niece is too rude, treat me as air?" ”

"No, brother, listen to me, Wenwen was not like this before, she used to be a very polite and good child, every time I came to school to see her, she would talk to me very enthusiastically about her, she has only recently become like this.

Look at her, she keeps her head down all day long, she doesn't want to speak, and she doesn't seem to listen to what others say. ”

Hearing him say this, Li Chenfeng looked at Wenwen's back carefully, and really felt that something was wrong.

"You wait here for a moment."

Saying that, Li Chenfeng followed alone, and then talked to Wenwen enthusiastically, although Wenwen ignored him at all, he still put a hot face on his cold buttocks, and as he spoke, he took advantage of his unpreparedness to put a willow leaf on her head.

"Wenwen, you don't seem to like to talk very much, then uncle won't bother you, go home obediently, don't play outside."

In this way, he watched Wenwen leave, and then Zhang Selling Dog came up and asked, "How is it, is it an evil spirit?" ”

Li Chenfeng didn't speak, led Zhang Selling Dog forward for a while, and then bent down to pick up the willow leaf that had fallen from Wenwen's head just now.

I saw that a willow leaf that was tender green just now had dried up and turned brownish-yellow, and there was still a black gas in the veins of the leaves.

Li Chenfeng nodded and said, "That's right, she is indeed stained with unclean things." ”
