"System, I want to know how to get grain seeds? And when are the crops harvested? Xiao Yi asked the key elements to survive in this wasteland world,

"Various seeds are obtained through random events, and due to unknown factors, the ripening time is greatly shortened, ranging from one week to several months."

"I choose random event ......" Although Xiao Yi ate canned food, he still felt very hungry, so he could only enter the world of random events to replenish it.

"Random Event Searching...... Search Success...... Disappear for 5 minutes, high school homicide. ”

A spatial crack appeared in front of Xiao Yi...... He felt a hard blow on his head, turning into white light and disappearing into the cracks.

"Raw Time Cooling...... Time Lapse Stops"

This was the last time Xiao Yi heard a prompt from the system, and when he slowly woke up, he found himself standing at the door of a building called "Yucai High School".

There were busy policemen all around, the police car had blocked the road, looked at himself, found that he was wearing a police uniform, and glanced at his police ID card, which read: Criminal police Xiao Yi, police number......

"Captain Xiao won't come in soon, I'll be waiting for you." The one who spoke was a policewoman, about 1.67 meters tall, with a goose egg face, wearing a mask, unable to know the specific face, and looking at Xiao Yi with an anxious look in her eyes.

Xiao Yi touched his stomach, now he wants to solve his own problem first, the homicide case can wait a while. But the people around him were staring at him, and the corners of his mouth rose slightly as he walked into the school.

The blockade had been drawn on the campus, and in an instant a strange memory appeared in his mind, and he knew that the policewoman who had just called him was Zhang Jing, the assistant of Zhang Ruoyun, the forensic doctor in the criminal police team.

"Team Xiao, where is Forensic Doctor Zhang investigating the scene in the men's dormitory building, I'll wait for you to pass." Xiao Yi nodded and glanced at the man who spoke. He is about 30 years old, with short hair, giving people the feeling of a greasy uncle, Wang Jun said as he took notes.

When I arrived at the scene of the crime, I saw a boy slumped in a chair, his head tilted back, no wounds on his body, and no blood on the ground.

Forensic doctor Zhang Ruoyun said: "The deceased was 20 years old. Died 1 hour ago, cause of death: suffocation. It is suspected that someone suffocated from behind with something covering their mouth and nose, and there are faint purple marks under the skin of the mouth. It is suspected that the murderer was left by the second injury. ”

Xiao Yi said: "Move me a chair."

Wang Jun behind him moved in a chair that was exactly the same as the deceased sitting from outside the door and placed it behind Xiao Yi.

Xiao Yi sat on the chair, tilted his head back, and said, "Forensic Doctor Zhang, you cover my mouth and nose from behind."

Zhang Ruoyun did so, and after a while, Xiao Yi said: "I just struggled for a long time, and I made a lot of marks with my hands back."

"But what does it mean that you look at the deceased and that he didn't struggle, and that the chair didn't even move?"

"Explain the ...... killed by the deceased after being subdued," Zhang Jing said.

"Wang Jun, you take Zhao Wen to investigate the relationship between the deceased, Forensic Doctor Zhang, I suspect that the murderer used something to make the deceased instantly incapacitated, and then killed, there must be residues in the blood. Over to you. After Xiao Yi finished speaking, his stomach screamed directly.

Wang Jing couldn't help laughing, and when she looked back and saw Zhang Ruoyun's eyes, she couldn't help it again.

Liu Xiaodong said: "Team Xiao, you go to lunch first, and we will investigate the matter first." I couldn't help but laugh after saying that.

"Jingle bell ......" a mobile phone rings.

Xiao Yi touched it and found that the mobile phone in his pocket kept vibrating, and took it out to see that it read: "Liu Ju."

"Bureau Liu, I'm Xiao Yi, and I'm at the scene of the crime now." Xiao Yi answered.

"Xiao Yi, the impact of this matter is very bad, some media have begun to report on the security problems in our city, and this situation has occurred, I hope you will solve the case as soon as possible." Liu Ju said.

"Hmm...... I estimate that it will take 5 days to solve the case......" Xiao Yi thought about it for a while.

"Forensic Doctor Zhang, is it a crime simulation for Team Xiao to sit on the chair just now?" Wang Jundao.

"Simulate what?" Liu Xiaodong didn't see the scene just now, and asked a little puzzled.

"Well, some excellent criminal investigation policemen often put themselves in the crime scene, sometimes imitating the murderer, sometimes imitating the deceased, to simulate the entire process of committing the crime, making judgments through assumptions and realistic situations, and figuring out the psychology of the murderer, or the behavior of the deceased before death. Analyze how the killer killed the deceased. Zhang Ruoyun said.

"I thought this situation would only appear in movies, but I didn't expect our Xiao team to do the same." Liu Xiaodong touched his head and said.

When Xiao Yi left, he said: "It is more likely that an acquaintance will commit a crime." I'll just go to the school cafeteria and solve it. ”

"What are you waiting for? Help put the body in the body bag. A few of you still expect Wang Jing to move alone. After Zhang Ruoyun finished speaking, he followed Xiao Yi towards the cafeteria.

"Bring me a set menu." Xiao Yi said to the cafeteria aunt.

The aunt looked at Xiao Yi suspiciously, a little suspicious, she didn't know the teachers at the school and had never seen this person.

"You are?" Auntie said.

Xiao Yi took out his police ID card, and then sat down. The aunt looked at it carefully, and returned the police officer card that was a little trembling to Xiao Yi.

"Sure enough, you still haven't changed...... Same as before. Zhang Ruoyun said with a little emotion.

sat next to Xiao Yi and said, "Give me a copy too, according to the standard of 15 yuan per person."

"Before...... What was I like before? Xiao Yi asked lightly.

"Well, you used to be so casual...... I don't care much about eating, I don't care about my body as soon as I start the case, because there was a problem with that case, you were transferred, and you have ...... until now" Zhang Ruoyun looked at the food in the cafeteria.

"Tell me what you think of this case, I took a closer look, there are no footprints around, and there is no problem with surveillance, I think the murderer will definitely not be so easy to leave us with the opportunity to view the surveillance." Xiao Yi looked at the food brought by the cafeteria aunt.

"The murderer must be someone who knows him very well, it may be his roommate, or a teacher, but at the time when he died, the school had already sounded the bell for the evening self-study preparation, so ......" Zhang Ruoyun said with a little hesitation.

"I still have something to ask about when you go back first after eating, I hope I can get the autopsy report tomorrow morning, I'm sorry for you." Xiao Yi thought of something as he ate.

Fifteen minutes later, he went to the victim's class and asked about the people in the dormitory.

"Wang Xing, Zhang Liang, Li Qiang, you guys come out for a while." The head teacher shouted directly.

When the three of them heard the words of the head teacher, they came to Xiao Yi with trepidation.

"Let's go, go to the playground, I have something to ask you." Xiao Yi said.

The head teacher looked at Xiao Yi taking away the three people, and hesitated to say something. In the end, I didn't say it.

"If you are asked to kill your roommates, how do you want to kill each other in the shortest possible time, think clearly and then answer." Xiao Yi said a little playfully.

Wang Xing hesitated for a moment and said, "Kill him while he is sleeping."

Xiao Yi suddenly put his head into his ear and said, "Who do you want to kill the most in the same dormitory?"

When Wang Xing heard this, he was so frightened that he took 2 steps back. A little frightened, he looked at the police officer in front of him. He felt that it was not the police but the devil, how could the police ask such a question.

Xiao Yi asked Zhang Liang and Li Qiang the same question with a smile on his face, and the reaction of the two was even stronger than Wang Xing.

The three of them are separated by a distance, you look at me, I look at you. They looked at each other with twinkling eyes.

Wang Xing was the first to walk to Xiao Yi's side and whispered a word, glanced back at the two of them, and ran back to self-study directly.

The corners of Xiao Yi's mouth rose slightly, the demon is on the left, the angel is on the right, everyone is an angel and a demon, Wang Xing has a motive to kill......

The other two looked at each other and took out the sticky notes and pens they had brought with them. wrote the names on it and handed them to Xiao Yi respectively.

Xiao Yi opened it and saw that it was written "Wang Xing", and the name written by Wang Xing was the name of the deceased.

Although he didn't know the specific situation, he felt that the case was not so simple.

Suddenly, the mobile phone rang again, and Zhou Zhen answered the phone. Wang Jun said directly.
