"Did you find anything?" Not far away, Conan's voice came from behind Chiba.

"Found something," Chiba said. "For example, the suspect or something, but I still don't know the specific methods of the murderer, after all, wild imagination is not what I am good at."

"I've got a clue on my side," Conan said, nodding. "Tell me what you found?"

So, Chiba told Conan what he had deduced before.

"Observation window?" Conan glanced at the location of the observation window. "Probably the optical instrument refracts the light... Let's take a look. ”

There are actually two doors in the screening room, one of which is the door through which Chiba enters the screening room from the screening room, and the other is on the other side of the screening room, leading directly to the staff lounge. The staff lounge also has a door that leads to a visitor passage from where employees can access the restrooms.

"Here..." Qian Yu looked at the staff lounge with some astonishment. "I haven't paid attention to this side yet...

"You're very focused on something," Conan squinted. "It's easy to overlook things that don't seem very important, and that's normal."

“。。。” Thousand Feathers pouted.

Conan's gaze was fixed on the wall of the staff break room.

"This..." Conan made a questioning voice as he walked over to the wall and carefully removed a small vanity mirror from the wall. "Mirrors?"

"What's wrong?" Qian Yu wondered.

"There's a mirror here... Conan showed the vanity mirror in his hand to Chiba.

"And then?" Qian Yu didn't know why.

"Then it's easy to solve." Conan shrugged. "At least in terms of technique, there are no more puzzles."

"Huh?" Thousand Feathers was stunned.

"Do me a favor," Conan commanded as he put his hand on Chiha's shoulder. "Go to the power room. When I called you, you turned on the air conditioner and adjusted the wind to the maximum. ”

"Where is the power room? What the hell is going on in this case? Qian Yu asked.

"The power room is next to the front desk, and you can see it when you go to the front desk. I'll tell you the details of the case when we go back, and we'll solve this case first. After Conan dropped this sentence, he took the mirror and left, leaving a confused thousand feathers.

。。。

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

He didn't have any assignments until Conan's phone call, and he could have thought about what was going on - after all, Conan had already revealed some information in that exchange.

1. The murderer (who is basically the sturdy projectionist) projects the projector projection into the viewing window through an optical refracting device.

2. This refractor device is likely to be the mirror that Conan was holding just now.

3. The setting of the whole case is likely to be related to the air conditioner.

Combining 1 and 2, it is likely that the reason why the murderer did this was to do something in front of the screening port - such as hanging the body of Masaji Zhangda.

However, when the body was found, Zhang Tian Zhengci was indeed shaking gently, if the sturdy man was really the murderer, how could it be that Zhang Tian Zhengci was still shaking ———— air conditioner at that time???

Qian Yu reacted immediately, and before Zhang Tian Masaji's body was discovered, he could indeed feel that the cold air had been adjusted to a very strong level. If the air outlet of the central air conditioner is facing Zhang Tian Zhengji's body, maybe the air conditioner with the most wind power can really blow Zhang Tian Zhengji to the point of slightly fluttering?

Just then, the phone rang—it was Conan. Qian Yu immediately turned on the power of the air conditioner, turned it to the maximum, and then left the power supply room.

He also wanted to hear what Conan's reasoning was!

。。。

When Chiba arrived at the screening room, Conan's reasoning was over, and he couldn't catch up.

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

"Why?" The director of the cinema seemed to be ten years older than he had been an hour earlier. "I thought you had a deep love for the cinema here... I didn't expect you to use this place as your killing place. ”

"Of course I love it here..." The projectionist smiled wryly. "That's why I do it because I love it so much."

“。。。” Everyone was silent, silently listening to the projectionist continue.

"I was recruited by Mr. Dean himself," the projectionist continued. "I'm 33 years old, I've been working here for 15 years, and it's like my home."

"At that time, the sound of the movie theater was very hot!" Speaking of this, a smile appeared on the corner of the projectionist's mouth, and it seemed that he really missed that golden period. "Every day after work, office workers can see that all the seats in the cinema are full, and there is laughter and laughter in the cinema every day. At that time, although my salary was not as high as it is now, I was still happy! ”

Chiba pursed her lips and closed her eyes. Although he usually watched movies by asking Master to borrow a videotape and show it at home, and rarely went to the cinema, he could still remember the grand occasion of the cinema ten years ago.

I think that the movie theater directors who lived through that era, and even the twilight police officers who didn't work in movie theaters, would have felt the same way as the young front desk attendants...

"But now, everything has changed." The projectionist's happy tone abruptly stopped, and it turned into a mournful tone. "Last weekend, it was even the whole day that only the little guy (who looked at the young man in glasses) to watch the movie. Cinemas, which used to be very prosperous, are already open... It's all because of that bastard Masaji Zhangtian! He was a ruffian every day, sabotaging our cinema so that we couldn't do it at all, and threatening us 'Unless you sell me the cinema, I'm afraid no one will be able to clean up the bad law and order here'!" They're just a bunch of scum! ”

"My favorite thing I used to do was to look at the whole theater full of people in the observation window. But now, that's all gone. The projectionist sighed. I hanged him here just to put him in this angle and let him see clearly what he had done. ”

。。。

Even long after the projectionists were taken away, the atmosphere of silence did not change.

"But actually, it's not entirely Zhang Tian Zhengji's fault." The cinema director suddenly sighed.

“？” Everyone looked at him.

"Urbanization brings convenience, but it also brings hustle and bustle and more entertainment. Cinemas, especially small cinemas like ours, are not in prime locations, and they don't have the financial resources to grab the right to screen popular movies, so they gradually decline... "The director of the cinema came to the observation window and looked at the empty screening room." In fact, before Zhang Tian Zhengji started to make trouble, our business had been slowly declining unconsciously, which is all a natural law... ”
