Conan's grammatical investigator

Chapter 251 Law of Mind Conservation

Hui Yuanai looked around at this moment and found that Qin Zhibo hadn't come yet.

After asking about the air conditioner just now, Qin Zhibo went to investigate elsewhere by himself.

Where can I go at this time?

If the case is not solved, Conan will.
Although Qin Zhibo took the lead in unraveling the mystery of Professor Hirota's death when they met for the first time, Haibara Ai thought that Conan was only mediocre as a detective.

But in the few cases without Qin Zhibo, Conan performed very well, worthy of his title of famous high school student detective.

Therefore, whether Qin Zhibo can beat Conan this time and take the lead in solving the truth of the case, Huiyuan Ai is not very sure.

At this moment, Qin Zhibo walked into the screening room under Hui Yuanai's expectant eyes.

"I already know the truth of the matter."

"Actually, this case is not a suicide, but a genuine homicide. The murderer is Mr. Guqiao, a projectionist at the movie theater."

Qin Zhibo's words exploded like a thunder in the brains of everyone in the projection room.

what!The murderer is the projectionist?

How did he do that?
Did he have two reels of Monster Gomera, one split in two and the other for censorship?
The ticket sales lady is actually an accomplice with him?
After all, if the cinema is gone, the work of both of them will be affected.
The moment Qin Zhibo announced the correct answer, Conan was 100% convinced that what Qin Zhibo said was correct, and began to deduce the answer from there.

"Brother Qin." Police officer Meguro on the side routinely doubted, "If it is the method of dividing the film into two parts, Conan has already said it just now."

"Mr. Guqiao has already explained this, but you were not here just now, so you didn't hear it"

Qin Zhibo was stunned for a moment, glanced at Conan and replied calmly: "Only children can think of such a level of technique."

This level of manipulation. Children.
Conan: Mentality -1
Hui Yuan Ai, who was at the side, came over and comforted him lightly: "It's okay, aren't you just a kid in the first grade of elementary school now?"

Conan: Mentality -1
Contrary to Conan, police officer Mu Mu beside the projector was very relieved after hearing Qin Zhibo's words.

Turns out I didn't think of splitting the film into two parts just because I'm not a kid
Police Officer Megumi: Mentality +1
Yup!

How can I be as good as a child in a police department?
Police Officer Megumi: Mentality +1
Before Qin Zhibo could wait for others to say the sentence pattern of "Mr. Guqiao, so he cannot be the murderer", he began to reason.

"Mr. Guqiao went outside this surveillance window to observe before making the move. After confirming that the deceased is still sitting in the previous position today, he began to execute the murder plan."

"The first thing is to go to the air-conditioned room and turn the knob of the air conditioner to the maximum, then come to the projection hall, approach quietly from behind, strangle the deceased, and hang him in front of the projection window."

As Qin Zhibo said, he pointed out to everyone the windows used by the murderer to commit crimes.

"At this time, there is a book behind the projection window where the deceased hanged himself, so no one can see the projection of the dead body on the big screen."

With that said, Qin Zhibo went to a side cabinet and took out a large blue book from inside.

"It was this book that was used at the time."

Seeing this, the staff of the cinema, especially the projectionist Gu Qiao, were stunned.

How did he know that I checked Zhang Tian's seat in the surveillance window before I attacked?

How did he know I was using the book to block the light?

Such a precise reasoning.
It's like seeing me commit a crime with your own eyes!
Although he was extremely surprised, Gu Qiao still forcibly calmed down, and asked in a slightly trembling voice: "If Zhang Tian was hanging there from the beginning, according to what you said, I would use that book to cover the projection window, and the movie There is no way to show it, right?"

Entering the link of seeking hammer and winning hammer, Qin Zhibo directly pointed to the staff rest room outside.

"Actually, you can do it with the mirror in the rest room"

"As long as the broken mirror is placed in front of the two projectors before the projection, and the angle is fixed, the film in the No. 1 projector can be played out from the No. 2 projection window next to it through light refraction."

"After you finish the murder, you just need to take away the book covering the No. 1 projection window, and then remove the mirror, and the normal projection of No. 1 projector will reflect the corpse of the deceased hanging in front of No. 1 projection window on the screen. "

"You turned on the air conditioner before killing someone, because you wanted the wind from the air conditioner to blow the corpse, creating the illusion that the corpse had just been hanged."

"By the way, when you were too anxious to put the mirror back in the rest room, the broken mirror accidentally cut the tip of the index finger of your left hand."

"And then you wrapped your mouth around the wound on your finger."

Hearing Qin Zhibo's last words, Guqiao trembled, and subconsciously clenched his left hand.

Police officer Mumu noticed something, stepped forward and grabbed Guqiao's left hand, and saw a small wound on the tip of the left index finger.

This wound is so small that it doesn't even need a bandage.

"How do you explain this?"

Police officer Mumu questioned him sternly, while Guqiao, who had already lost his spirit, slowly lowered his head.

At this time, the ticket sales lady at the side justified her exit and said: "I remembered, he just cut Guqiao this morning!"

Qin Zhibo smiled slightly, "This method of using light refraction for projection still has a drawback."

"The clarity of the film projected by mirror refraction is absolutely not as strong as that of normal projection."

"Didn't that college student happen to take photos during the film screening? Just show it again normally and take pictures under the same conditions, and you will find the difference in clarity."

"Other than that, as long as you look carefully."

Before Qin Zhibo could finish his sentence, Gu Qiao, who had already bowed his head, said, "You will find that the size of the projected picture after using the mirror will be narrower than the normal projected picture, and the picture will also be narrower due to the change of focal length when the mirror is switched. Faint"

"I have quietly tried this technique more than a dozen times when there is no one in the theater, so I am still clear about the difference."

"So you're admitting your crime?"

Facing the serious police officer Mu Mu, Gu Qiao nodded heavily.

"Everyone, I'm sorry for causing such a big incident"

Afterwards is the usual motivational moment, but Qin Zhibo is completely in the mood to listen to these things right now.

Because the more important thing now is the task reminder.
