"Ah Cheng," said Gao Cheng mysteriously in the garden corridor, "I heard from the students here that a student named shencho hanged himself half a year ago, but the teachers concealed it."

"Half a year ago?"

Gao Cheng thought about the motive of the case.

"Yes," Yuanzi said fearfully, "I heard that since then, there has been the curse of shencho in the school. There is still a cursed oil painting in the art classroom. Oh, the hair of the woman in the painting grows every day!"

"Why did you commit suicide?"

"It seems that they are often bullied, the two people who died this time..."

Art room,

Gao Cheng follows the garden to find the cursed painting.

A gentle woman embraces the baby and the painting name is "Lullaby".

"I have my old photos," Yuan Zi said, opening his mobile phone photo album. "I used to have short hair, but now I have a long one."

Gao Cheng carefully contrasts and touches the paint.

He is not unfamiliar with the phenomenon that women's hair grows longer in the paintings. In order to hide the real paintings, he repainted them on the surface with pigments that are easy to fall off. There have also been such cases in the history of art.

Even before, he met in a Nagano case.

It's not a curse at all

"Is the author of this painting the suicidal shencho?" When Gao Cheng saw the signature, he said it out of his mind.

"That's right."

A girl with long hair appears behind them strangely. Yuanzi is almost scared to pee. She screams and hugs Gao Cheng.

"The soul of Shen Cho's classmate lives in this painting," the girl said with a nervous smile. "Those two guys are haunted by Shen Cho's dead. Ha ha!"

Gao Cheng watched the girl leave madly, shaking his head and saying, "I feel that the people in the cram school are strange. How can you come to such a place in the garden?"

Yuanzi: "I failed the math exam last time, so..."

Gao Cheng: "just ask Xiao AI to make up for your lessons."

"Xiao AI is more terrible."

……

"Police department!"

Maori xiaowulang ran back to the scene of the crime from the staff office, waving an answer sheet excitedly.

"I know what's going on! Does Mr. Ono have an alibi? "

"What?" Originally prepared to return to the police station, Mu Mu looked at Uncle doubtfully, "what do you find? I don't have time to beat around the bush with you, brother Maori! Really, every time... "

"It's true this time!"

Uncle quickly gave the answer sheet to Mu Mu.

"There were three examinations here yesterday, two in the morning and one in the afternoon. The time when jento was killed was just after the second one. But you see, this is the answer sheet of Shijing's third examination,

That is to say, Ishii was killed after the third exam, but Mr. Ono had been taken to the police station at that time, right? "

"Is that true?" Mu Mu is surprised to check a way, "true, so the teacher Ono has alibi... But just now she has already confessed in the police station, what's the matter?"

"Do you still need to say, police department?" Uncle anxious way, "must be Ono teacher want to cover up the prisoner, that is, a student of this school!"

"Well," murmur said cautiously, "it seems that we need to start a new investigation. Then, please solve the mystery of the chamber of secrets, brother Maori!"

In the afternoon, the police found the stuffed inflatable doll in a clump of grass outside the window of the secret room.

Uncle Maori felt that he had solved the puzzle and called everyone to a classroom.

When Gao Cheng and Yuan Zi came over, they met the woman teacher who was brought back from the police station.

It's really beautiful

In addition, the aura of teachers who love students, according to uncle's logic, is that it can't be the kind of gentle type of murderer.

The most terrible thing is not this point, but Uncle Maori, who has always been confused, actually found a favorable clue this time, even when Conan didn't come.

It's more than extraordinary play

"Ladies and gentlemen," Maori Kogoro coughed softly, "I think you all know the details of the case. Now what I want to say is that Mr. Ono can't be the murderer at all. The evidence is the answer sheet I have,

This is the proof that Shijing took part in the third exam. At that time, Mr. Ono was taken to the police station, so it was impossible to kill Shijing. Of course, it was impossible to kill jento, because they were obviously killed by the same person.... "

"But what about the chamber of secrets, brother Maori?" Mu Mu asked suspiciously.

"In fact, we made a mistake at the beginning," uncle said confidently. "The body Mr. Ono saw at first was not a corpse, but a camouflaged inflatable doll. The window of that room was very small, and it was normal to make mistakes under insufficient light,

The evidence is the inflatable doll found outside the window, which should have been thrown out of the small window by the prisoner

Mu Mu: "what's the matter with the corpse? How are the prisoners going to get out? "

Maori hummed and laughed: "it's very simple, because the body is the prisoner himself! This is a suicide case designed to frame Mr. Ono! "

"Self, suicide?"

There was a cry of surprise in the classroom.

"Did they plan this by themselves?"

"That's right," Uncle nodded. "I'm afraid it's because of too much pressure. When I commit suicide, I want to take revenge on Ono!"

No

Gao Cheng's brows are getting tighter and tighter.

Uncle's reasoning sounds like nothing wrong, but it's not right at all.

If the two students want to commit suicide, there is no need to have anything to do with "the curse of shencho".

Anyway, it's murder

But what about the answer sheet?

Did Murai really take the third exam?

Or is Shijing really killed after rindo?

After the first two exams, the rest time was as long as 30 minutes. It should be at that time that Ando was killed. Then when the third exam started, the lullaby sounded and the body was found.

So, what about the time of Murai's death?

If Ono is the murderer, he must kill Shijing before rindo

"I see." Gao Cheng suddenly raises his head. Regardless of the surprise of the people around him, he runs into the staff office.

The killer would set the lullaby to be played at noon the next day, of course, so that the police could not accurately determine the time of death.

If you want to have an alibi, you have to make the police feel that the killing time of Ishii was after the third exam, so they did a series of tricks.

Including deliberately leaving blood words at the scene.

It makes people subconsciously think that the killer committed the crime in character order.

As for the evidence of the answer sheet

"Sure enough," Gao Chengfan said after reading all the answer papers of the three exams and confirming his guess, "with the one in uncle's hand, there are only two answer papers of Shijing. If Shijing didn't take part in the first exam, it means that the killer replaced the answer paper..."

"What do you mean?" Yuan Zi, who helped to sort out the answer sheet, said, "Shijing did fill in the answer sheet of the third exam, and didn't the police also say that? On it is the handwriting of Shijing... "

"What if it's not the third exam?" Gao Cheng interrupted, "except for the beginning serial number, the answer papers of several exams are completely the same, so it's possible that Shijing filled in ahead of time..."

The serial numbers of the three test papers are 15, 16 and 17 in turn, but only 16 and 17 in Shijing.

Obviously someone did something

Gao Cheng asked, "who are the invigilators for the first two exams?"

Yuanzi: "of course, it's Mr. Ono. My test paper was handed out by Mr. Ono himself.

"That's right."

All the clues are combined in Gao Cheng's mind, and he has solved all the female teacher's techniques.

"There's only one problem left, motivation."

In the art room, Gao Cheng and Yuan Zi come to the cursed painting "Lullaby" again.

"Ah, ah Cheng?" Yuanzi felt that there were some people in the art room. He retreated and said, "you'd better go back. Maybe you'll be cursed..."

"I want to confirm one thing."

Gao Cheng took an art knife and began to shave from the part of his hair that became longer in the oil painting.

Gradually, the watercolor paint on the surface of the painting fell off, revealing an earring in the part of the woman's ear.

It's the same as the female teacher's

That should be the motive.

The relationship between female teachers and shencho is likely to go beyond the teacher-student relationship.

……

It's the same classroom as before, but this time it's Gao Cheng.

"Hey, what the hell is going on?" "We are also very busy," complained a male tutor

"Didn't you find out that it was suicide? What's going on, officer? "

"You don't have to worry," Gao Cheng said, holding a pile of test papers on the platform. "Next, please do a test for me."

"Test?" Ono opened his mouth unexpectedly.

"That's right," Gao Cheng said, distributing the questionnaire. "There are 50 questions, each with five options. Please choose the one that you think is the most correct. If you are not sure, you can choose any one,

The test time is 15 minutes from now. Please start to answer the questions. "

"That's true," the male tutor said with a questionnaire. "What kind of questions are these

The first question is where to buy the rope if you want to hang yourself.

15 minutes later, the questionnaire was collected by the police and returned to Gao Cheng after the correction.

"Well, can you tell us now?" The male teacher asked, "what's the point of doing this kind of investigation?"

"This questionnaire can find out the real murderers of rindo and Ishii." Gao Cheng looks at the score track“ The above questions are basically criminal clues investigated by the police. For example, the source of the rope in question 1 is from the interlocking convenience store, so the answer is the convenience store in the option. Other questions are almost the same. Except for the police, only the real murderer knows the correct answer to the questionnaire, but after the murderer knows this, I'm sure I'll deliberately avoid the correct answer... But I didn't expect that the murderer avoided all of them. All of the 50 questions were wrong. The probability of getting zero is only four fifths to the 50th power, which is one in 70000. But some of us got this score. " Gao Cheng's eyes fell on the silent female teacher“ Mr. Ono, the murderer of rindo and Murai, is you all wrong? "“ Are you kidding? " Uncle Maori responded strongly and said, "doesn't Mr. Ono have an alibi?"“ That's the alibi she specially arranged, "Gao Cheng explained." the reason why she asked detectives to investigate pranks is to help her find alibi. It's just a part of the plan. "“ How is that possible? Can't an alibi be false? "“ Uncle, you can ask those examinees again. Indeed, every time you take three exams, you will draw lots to change seats. It's normal if you don't see Shijing, but what if everyone doesn't see Shijing? Is it normal? " Gao Cheng took out the answer sheet of Shijing No. 16 and the standard answer sheet of Shijing No. 15“ This answer paper of Murai actually corresponds to the serial number 15, that is, in the first exam, the answer paper given by the prisoner to Murai is the answer paper of the next exam 16. Similarly, in the second exam, the answer paper given by the prisoner to Murai is the answer paper of the serial number 17. I looked through all the answers of the three exams and came to the conclusion that Murai only took two exams, He was killed before the third exam, or before rindo. " Maori Kogoro's face was stiff: "this... How can it be like this?"“ Now you know? " Gao Cheng continued, "teacher Ono's alibi doesn't exist at all. Whether it's the previous chicken killing prank, or the blood words on the scene, as well as the examination papers, it's just to mislead the order of killing and create an alibi for himself."“ "Mr. Ono..." uncle was deeply hit. He couldn't believe it. He looked at the female teacher, "is it true? You're just using me? I believe you so much... "When you think about it carefully, it seems that he was indirectly guided by the female teacher. Uncle is a few years old in an instant“ But what about the motive? " Mu Mu hastily asked, "what is the motive of teacher Ono?"“ The motive should be this painting. " Gao Cheng brought the lullaby from the art room to the stage“ As like as two peas, the painting is painted on the basis of the original painting. The painting is easy to fall off. After painting, a part of the ear can be seen. Actually, it is wearing an earring. Mr. Onokazu is exactly the same as the one on your ear. The female teacher looked up at the painting, her eyes gradually moist“ A few days later, Gao Cheng came to the cram school to pick up the garden. This time, he got a "Mathematics" card. Unfortunately, it couldn't be handed over to Yuanzi. In the end, he just promoted his "Mathematics" to the proficient level. A little is better than nothing, but it corresponds to the university level, which can make his later study much easier“ Ono has pleaded guilty, "Yuanzi said in low spirits." the third person she wants to kill is the long haired boy who said Kaodong University. It seems that shencho was hanged by the three men six months ago... "Gao Cheng pauses, remembering the long haired man who satirized him and Yuanzi in the corridor. Are all the people in Kaodong university like this? Or is it the problem of this tutorial school? It's a big problem that students often commit suicide... What do parents think of sending their children to such schools? Gao Cheng shook his head and saw that the garden was unhappy. He took the garden by his hand and said, "there's a new western restaurant over there. It's called AI. Let's have a try." Yuanzi: "that Aini restaurant is very popular. I have to make a reservation."“ What kind of restaurant“ Annie... Asshole, don't think I don't know Chinese! "
