Jian Jing was quite unhappy.

I played the game for four and a half hours, and the reasoning took no more than half an hour. The rest of the time was spent on sorting out the emotional drama. You love me and I love you, love back and forth, endlessly, and there was no decisive evidence.

The real murderer was particularly arrogant.

Ji Feng comforted her: "They are just here to socialize, it's normal that they don't take the case seriously."

Jian Jing pursed her lips: "Forget about the guests, but what about the script? This is a scam."

"This is a game, it's fun only if you can pass it. If it's too difficult, the guests can't solve it. Besides, the case is not too outrageous, it's a bit clever." He commented objectively, "It's just that there are too many emotional scenes, and the main and secondary are not distinguished.

" "Yes, look at the evidence found, all related to emotional scenes." Jian Jing was so angry that her teeth itched, "After the code was unlocked, it turned out to be a love letter, what romance, who wrote the script, rubbish."

Ji Feng had never seen her like this before, and couldn't help laughing: "Okay, okay, don't be so serious, ah, I'll treat you to dinner."

Jian Jing: "What are you eating, hurry up and solve the Miao Tong case."

"That's fine." Ji Feng nodded indifferently, "First of all, Miao Tong is not a pure victim." Jian Jing

calmed down and said, "This can explain the fingerprints on the railing. Miao Tong did climb out by herself, but it was not necessarily for suicide. It is possible that she wanted to make others fall."

"But in the end, she fell down. Was it an accident or human error? I'm afraid we have to ask the murderer." Ji Feng sighed and was quite entangled. "It's not easy to deal with. She's still a student. If she's not handled properly, it will affect her whole life."

"Suicide and murder will definitely have different effects on students." Jian Jing thought about it and said, "Find evidence first?"

Ji Feng asked, "Go now?"

"Yes." Jian Jing had been holding back her energy for four hours and had to finish it today, "Anyway, they still have evening self-study."

Ji Feng had no choice but to accompany her to the school again. After some effort, he found the evidence and sent it back to the bureau for inspection.

It happened to be Lao Gao's turn to be on duty today. When he saw the two of them together, he immediately became energetic: "Hey~~"

"Officer Gao, long time no see." Jian Jing greeted with a smile.

Lao Gao made a seat for her: "Have a seat, Teacher Jian, where are you from?"

"The crime scene." She asked curiously, "What are you busy with?"

"A home robbery."

Jian Jing: Heping City is still as "peaceful" as ever.

Ji Feng returned after handing in the materials: "I jumped the queue, the results will be out tomorrow. Teacher Jian, can I take you home?"

Jian Jing pretended not to hear and strolled around.

In the interrogation room, a suspect was confessing his crime.

She stood on tiptoe to take a look.

"Teacher Jian, let's go to eat, ah." Ji Feng quickly grabbed her and dragged her out, "You can't look, don't look, he has confessed. Damn it, don't play any scripted killings in the future, this is not suitable for a professional like you..."

After struggling, he finally stuffed the man into the passenger seat.

Ji Feng breathed a sigh of relief. He had arrested suspects in the three digits, and none of them was so difficult.

"What's wrong with taking a look, you are so stingy." Jian Jing crossed her arms, still angry.

Ji Feng: "There's no use for you. You should rest early and go to bed early today. Tomorrow morning, we will solve this case, okay?"

Jian Jing reluctantly said, "Okay."

"What are you having for dinner?"

"I'm not hungry."

"It's eleven o'clock. You have to eat something. Noodles ?

" "No."

"Barbecue?"

"I don't want to eat."

Ji Feng glanced at her and said, "Give me some clues."

"Hot, soft, salty and not greasy. No porridge or noodles."

Ji Feng: "Then eat rice noodles. I can't object. Who told you not to rule it out just now?"

Jian Jing was puzzled: "What's the difference between rice noodles and noodles?"

"One is rice and the other is wheat. There is no difference?" Ji Feng was even more puzzled than her.

"No rice noodles, no wontons, no dumplings, no pan-fried dumplings."

Ji Feng: "Rice cakes."

Jian Jing was convinced: "The idea is really clear, how about screening and eliminating according to the raw materials?"

"Do you want to eat it?"

"Spicy stir-fried rice cakes."

Although she said so, but when she arrived at the Korean restaurant, Jian Jing's appetite returned.

She ordered a spicy stir-fried rice cake, a sweet and spicy fried chicken, a buckwheat cold noodles, and grilled pork belly.

Ji Feng: "..."

So just now, no greasy, no noodles, no grilled, just casual talk?

Women are really fickle creatures.

The next day, the weather was clear and the sun was shining.

Squad Leader Wu came to the rooftop of the experimental building and saw Jian Jing holding a parasol and wearing a French floral dress.

She smiled and said, "Nice to meet you again."

"Teacher Chen said you have something to talk to me about." Squad Leader Wu asked politely, "How can I help you?"

"You can help me sort out some thoughts." Jian Jing took off her sunglasses, "Is today's weather similar to the day Miao Tong died?"

Squad Leader Wu: "What do you mean?"

Jian Jing took out a stack of papers from her bag: "Take a look."

Squad Leader Wu took it, his fingers stiff. On it were some printed screenshots, the content was a radical speech posted by a certain account on various platforms, and some sentences showing off the abilities of one's own relatives.

"You deleted the message, but Miao Tong has taken screenshots and saved them all. We found this in the encrypted file on her computer." Jian Jing said, "It's you, right?"

Squad Leader Wu said stiffly, "I don't know."

"Lying is not a wise choice. You should know that with today's technology, it's not difficult to find out who it is. But you are still a child, so it's not surprising that you have a lucky mentality."

Jian Jing said slowly, "Let me explain everything to you."

"On the day of the incident, Miao Tong asked you to meet in the laboratory building. I think the purpose was to threaten you to give up your recommendation quota, otherwise she would make it public. Then, not only would you lose your quota, but your uncle, the principal, would also be implicated. You had no choice but to keep the appointment." "

At 14:20, you started your physical education class. You first went to the gymnasium with your classmates to borrow equipment, and then went to the basketball court with everyone else. No one would suspect you, as it was natural for boys to play basketball. If you left, everyone would just think that you, a good student, had to review and came here just to look after your classmates.

"But in reality, you came to the laboratory building quietly, and in order to avoid being recognized, you changed into cleaner's clothes at the back of the stairs on the bottom floor of the first floor. "

Although the murder story in the script is terrible, it is surprisingly coincidental with reality.

In the hotel fall case, the murderer used the location to cleverly create a real secret room. In reality, the testimonies of three eyewitnesses also happened to constitute a surveillance-type secret room.

Ji Yunyun and others behind the experimental building only saw Miao Tong going there.

The cleaner on the left side of the first floor only heard the footsteps of one person. The young couple who were having a tryst on the right side of the first floor only saw the cleaner and no one else.

At first glance, It seemed that there was no suspect at all.

But Jian Jing remembered that the girl said that there was lush wisteria where they had a date (this key sentence did not appear in the police confession and was ignored by the person involved). She went to the scene to check and found that there were indeed lush flowers and leaves, but they were in the middle.

Only there could they block the view of the office building and have a secret date.

Similarly, because of the obstruction of the branches, they could not see the cleaner who was cleaning on the left.

So, who was the cleaner?

Of course, it was the other person who had a date.

"We found the clothes you stole in the office of the school worker. Fortunately, we collected some hair and dandruff. We can tell who it belongs to by comparing DNA."

Jian Jing reminded him: "Do you have anything to say? Turning yourself in can get a lighter sentence. You are still young. "

I didn't kill her." Squad Leader Wu clenched his fists and said firmly, "She fell down by herself."

Jian Jing raised her eyebrows: "Really? Let me remind you, there is more evidence than what I said, you'd better tell the truth."

"What I said is the truth." He did not change his words, "The day before, Miao Tong asked me to go to the laboratory building for physical education class, but at noon, I saw her going there mysteriously. I was very worried, so I followed her."

Jian Jing waited for him to continue.

Squad Leader Wu paused and continued to explain: "She sneaked upstairs, pried open the lock of the roof, and climbed over the railing and stuck something there. I thought she was hiding something, so after she left, I took the thing away immediately. "

"Then what? "

Then I pretended that I knew nothing. During the physical education class, I sneaked up as you said. At that time, she seemed to have discovered that something was missing. I thought the problem was solved, but she took out the USB flash drive and threw it outside the railing."

He took a deep breath and held back his anger: "She said she would delete the things, but she copied them again and again. I was so angry and asked her what she was doing. She was guilty and scared, and she fell down without standing firmly."

"I was scared." Squad Leader Wu's voice became dry. "At that time, everyone heard the noise and gathered over. I didn't dare to stay there any longer, so I changed my clothes and pretended that I knew nothing... But I really didn't kill her, she fell down by herself. "

Jian Jing declined to comment.

For now, squad leader Wu's testimony is consistent with the evidence - the school's surveillance camera captured him and Miao Tong appearing near the laboratory building at noon.

But the most crucial part, whether Miao Tong fell accidentally or was pushed down, remains to be discussed.

"We found your fingerprints on Miao Tong's clothes." The sun was too strong, and Ji Feng had been standing in the shadow behind the door. He just appeared and reminded him, "At the shoulder blade."

Squad leader Wu said, "She and I are in the same class. It's not strange that I patted her shoulder."

"Why did you go up wearing the cleaner's clothes? Obviously, the evidence has been taken away by you, and you could even not keep the appointment." Jian Jing hit the nail on the head, "But you still had to dress up, and even forged a suicide note afterwards. "

She took out the suicide note sealed in the evidence bag and said, "There are traces of a blade cutting on the edge of the paper. If I'm guessing correctly, this is the sample you deliberately asked Miao Tong to write. You cut off a part of it, and it became a suicide note. "

The original suicide note was as follows:

After thinking it over, I still can't accept it.

I have decided to give up. I

'm sorry, please forgive my willfulness.

As a suicide note, the content is too general and abstract. What can't be accepted? What to give up? Who is the recipient of the letter? None of them are specified.

But if it is expanded, the content is obviously more reasonable, for example:

Teacher X, after thinking it over, I still can't accept

it. I have decided to

give up the recommendation. I'm sorry to let you down. Please forgive my willfulness.

I still plan to go to the ideal university based on my own grades

...

"I changed my clothes just because I was afraid of being seen by others. I can't let this matter get out. "Class monitor Wu defended, "I only thought of writing the suicide note later. She asked me to write it, saying that she was afraid that I would lie to her, so she had to write such a letter personally. She put it in the principal's mailbox, but I didn't have time to take it back that day... I was so scared. Her inexplicable death in the laboratory building would definitely arouse a lot of suspicion. If people knew that I was here at the time, I would be doomed!"

He said painfully: "Anyway, it was an accident. I just want to treat this as suicide... It's good for everyone."

"What you mean is, when you saw Miao Tong fall from the building, you first ran down to see the body, and then returned to the teaching building in the chaos, found this letter, and in front of so many classmates in the classroom, cut off a part of it, pretended it was a suicide and stuffed it into Miao Tong's drawer? "Jian Jing asked back.

Squad Leader Wu said: "Yes, everyone was scared at that time and no one noticed. I really only thought of it after she died."

Jian Jing sighed lightly, and suddenly became serious: "I gave you a chance."

"That noon, Miao Tong bought a box of yogurt. It was the new cherry flavor that day." She took out a box of fresh yogurt like a magic trick, "See, it's with the lid off, and it comes with a small spoon."

Squad Leader Wu showed a puzzled expression.

"According to the testimony of eyewitnesses, Miao Tong ate yogurt before the physical education class, and milk stains of this yogurt were detected in the suicide note." After remembering 1, Jian Jing's memory ability increased a lot, and she still remembered the testimonies of Ji Yunyun and Xiao Xiao.

At that time, no one thought that this would be such an important evidence.

"When the police checked the drawer of the desk, they did not find any unfinished yogurt, proving that she had finished drinking and thrown it away before leaving. If you put the suicide note after the incident, how did it get stained with milk?"

Wu Jincheng's face was pale, his brain turned rapidly, but he didn't know how to refute this strong evidence.

Jian Jing ended her speech neatly and clearly: "There is only one answer. You put the suicide note before the physical education class. That means that at that time, you had already decided to kill Miao Tong."

There was silence at the scene.
