"Did you discover anything?" Not far away, Conan's voice came from behind Qian Yu.

"Some things were discovered," Qianyu spread his hands. "For example, a suspect or something, but I still don't know the specific methods of the murderer. After all, imagination is not what I am good at."

"I have some clues here," Conan nodded and said. "Tell me what you found?"

Therefore, Qianyu told Conan the conclusion he had previously deduced.

"Observation window?" Conan glanced at the location of the observation window. "It's probably the optical instrument that refracts light... Let's go take a look."

There are actually two doors in the screening room. One of them is the door through which Qianyu enters the screening room from the screening room. The other is on the other side of the screening room, leading directly to the employee lounge. There is also a door in the staff lounge that leads to the visitor passage.

door from which employees can access the restroom.

"Here..." Qianyu looked at the employee lounge with some surprise. "I haven't noticed this side yet..."

"When you are very focused on something," Conan squinted. "It's easy to overlook things that don't seem to be very important. This is normal."

"..." Qianyu curled his lips.

At this time, Conan's eyes were fixed on the wall of the employee lounge.

"This..." Conan made a questioning voice as he walked to the wall and carefully took down a small dressing mirror hanging on the wall. "Mirror?"

"What's wrong?" Qianyu asked confused.

"There is a mirror here..." Conan showed the dressing mirror in his hand to Qianyu.

"Then what?" Qianyu asked, not knowing why.

"Then it will be easily solved." Conan shrugged. "At least in terms of technique, there is no longer a puzzle."

"Huh?" Qianyu was confused.

"Do me a favor," Conan put his hand on Qianyu's shoulder and instructed. "Go to the power supply room. When I call you, turn on the air conditioner and adjust the wind power to the maximum."

"Where is the power supply room? What is going on with this case?" Qianyu asked.

"The power supply room is next to the front desk. You can see it when you go to the front desk. I will tell you the details of the case when I get back. Let's solve this case first." After Conan left these words, he took the mirror and left.

Qian Yu was left alone and confused.

...

Qianyu walked into the power supply room, turned on the light, and quickly found the power supply for the air conditioner.

Before Conan's call came, he didn't have any tasks. He could completely think about what was going on - after all, Conan had already revealed some information in the exchange just now.

1. The murderer (basically the muscular projectionist) projects the image projected by the projector onto the observation window through an optical refraction device.

2. This refraction device is probably the mirror that Conan was holding just now.

3. The setting of the entire case is probably related to the air conditioner.

Combining 1 and 2, the reason why the murderer did this was probably to do something in front of the projection port - such as hanging the body of Masaji Harita.

However, when the body was discovered, Harita Masaji was indeed shaking slightly. If that muscular man was really the murderer, how could it be possible that Harita Masaji was still shaking at that time - air conditioner???

Qianyu reacted immediately. Before Masaji Harada's body was discovered, he could indeed feel that the air-conditioning had been adjusted to a very strong level. If the air outlet of the central air conditioner was facing the body of Masaji Harada, perhaps the air conditioner with the highest wind power would be really powerful.

Can it blow Haruda Masaji to the point where he is slightly fluttering?

At this moment, the phone rang - it was Conan. Qianyu immediately turned on the air conditioner, adjusted it to maximum, and then left the power supply room.

He also wants to hear what Conan's reasoning is!

...

When Qianyu rushed to the screening room, Conan's reasoning had already ended and he failed to catch up.

When he arrived, the burly projectionist had already lowered his head and allowed the police officer in front of him to handcuff his hands.

"Why?" The director of the cinema seemed ten years older than an hour ago. "I thought you had a deep love for the cinema here... I didn't expect that you actually used this place as your murder place."

"Of course I love this place very much..." the projectionist smiled bitterly. "That's why I do this because I love this place so much."

"..." Everyone fell silent, listening quietly to the projectionist's continued words.

"I was personally recruited by Mr. Dean," the projectionist continued. "I am 33 years old and have worked here for 15 years. This is like my home."

"At that time, the sound of the cinema was very prosperous!" When he said this, the projectionist's mouth showed a smile. It seemed that he really missed that golden period. "Every day after work, office workers can see the cinema.

All the seats were full, and there was laughter and laughter every day in the cinema. Although my salary at that time was not as high as it is now, I was still happy!"

Qianyu pursed his lips and closed his eyes. Although he usually watched movies by asking his master to borrow the video tape and then show it at home. He rarely went to the cinema to watch it, but he could still remember the grand scene of the cinema ten years ago.

new.

Come to think of it, the director of the cinema who experienced that era, even the police officer Megure and the young front desk clerk who did not work in the cinema would have the same feeling...

"But now, everything has changed." The projectionist's happy tone suddenly stopped and turned into a sad tone. "Last weekend, there was only that little brother all day long (when he said this, he watched

I asked the young man with glasses) to watch a movie. The movie theater that was once very prosperous has been depleted... This is all because of that bastard Haruda Masaji! He is a gangster who destroys our movie theater every day, making it impossible for us to operate.

Threatening us, 'Unless you sell the cinema to me, no one will be able to clean up the bad security environment here'! They are a bunch of scum!"

"My favorite thing in the past was to be at the observation window, watching the whole screening room full of people. But now, all this is gone." The projectionist sighed... "I'll hang him here.

It’s just to put him in this perspective and let him see clearly what he did.”

...

Even long after the projectionist was escorted away, the atmosphere of silence did not change.

"But actually, this is not entirely Masaji Harita's fault." The director of the cinema suddenly sighed.

"?" Everyone looked at him.

"Urbanization has brought convenience, but it has also brought hustle and bustle and more entertainment. Cinemas, especially small cinemas like ours, are neither in prime locations nor have enough financial resources to grab the right to screen popular movies.

So it gradually declined..." The director of the cinema came to the observation window and looked at the empty screening hall. "Actually, before Harita Masaji started causing trouble, our business had been slowly declining without knowing it.
