Finished chatting off topic.
Memu Shisan began to re-examine the case in front of him:
"That means the first people to discover the body were Mr. Xinghe, Xiaolan and Kazuye, right?"
"Yes."
Xinghe Tongwu nodded:
"When we first arrived, there was nothing in the corridor. It was too dark, so I pressed the light switch. As a result, even the light on the stairs went out. After a while, when the call came, we I saw Miss Zhanzi lying motionless in that place."
"Brother Gengyi has just confirmed the cause of the power outage."
Hattori Heiji walked to the wall and removed the switch panel that was hidden, "Police Department, please ask forensic personnel to collect evidence directly. Someone has tampered with this. As long as the power is turned off, it will cause a short circuit."
"Ah, oh..."
Megure Thirteen went over to confirm the situation, turned around and was about to call Takagi Wataru to go downstairs to call someone, but in the end he was in vain.
Where are people?
"Megure Police Department, if you are looking for Officer Takagi, I just saw him being called away by Brother Sarai." Conan said.
He actually considered whether to follow and eavesdrop.
But then they thought about it. The crime scene was on the second floor. The most they could do if they went to the first floor was to go to the yard and the surrounding area to check for possible traces left by the murderer.
After Officer Takagi comes back later, he can figure it out casually.
Since the case cannot be solved so quickly, the most important thing at the moment is to listen to the confessions of a few people and monitor whether Xinghe Tongwu will do anything untoward towards Xiaolan.
…
Hallway in front of the bathroom on the first floor.
After Ye Gengyi called a police officer in a gray suit here, he directly stated the conclusion of the murder case.
"What?! The murderer is Xinghe Tongwu?"
Takagi Wataru showed a surprised expression.
"Don't make any noise yet. I just brought this from the room on the second floor."
Ye Gengyi handed over the photo of Mrs. Zhengying and said, "Ask the police to go to a nearby convenience store that is about 10 to 20 minutes away and ask if this woman bought any condiments around 7:30." "
"oh."
Takagi Sheba took it honestly, ran to a police officer and muttered for a while. After watching the other person go out with the photo, he ran back again, scratched his head and guessed:
"Mr. Ye, do you suspect that Mrs. Zhengying is also an accomplice of Mr. Xinghe in killing Miss Zhanzi?"
"Well, she must know the loopholes in Xinghe Tongwu's alibi. Since she didn't say it out, she was either an accomplice or a cover-up. We will know after the investigation."
Ye Geng paused, then signaled Gao Mushe to take out his notebook and ballpoint pen, and said step by step: "You have also been to the second floor. You should have noticed that the corridor over there is very narrow, right?"
"Well, that's right," Takagi Wataru agreed. "It feels like once the door is opened, no one can get through."
"The owner of the house deliberately designed it this way," Ye Gengyi drew an angle in the air with his finger. "The door opens to the outside at about 60 degrees. The frame of the door will touch the wall of the corridor and block the corridor at the same time. Window and cabinet at the end.”
"Covered?" Takagi Wataru caught the key word.
"This is a photo I took with my mobile phone..." Ye Gengyi asked: "How is your spatial thinking ability?"
"Alright, it's okay."
Takagi Wataru didn't know what the criteria for this answer were, but he was just an ordinary detective, so it was better to be humble in front of Professor Ye Gengyi.
"Practice more when you have nothing to do," Ye Gengyi said calmly: "After you know your step length, you can go to a familiar place and observe the surrounding scenery, then close your eyes and try to go to a designated place, and finally see what's going on. How much is the deviation?”
"Uh...well..."
Takagi Wataru didn't know why, but he suddenly felt like he was dreaming about going back to school, when he was called by the teacher to answer questions in class, and then was given homework after class.
…I’m already starting to get scared.
"How do you like the photo?" Ye Gengyi asked.
"Ah? I, I haven't read it yet..." Takagi Wataru scratched his head.
Weren't the two of them chatting just now?
"..."
Ye Gengyi was silent for a moment, "Look slowly..."
My own problem is that I really shouldn’t be in a hurry when chatting with someone who can’t be distracted.
Minutes flew by.
Although Ye Gengyi still maintained his calm appearance and did not speak to urge him, Gao Mushe still felt great pressure.
There are only six photos in total on the phone.
One of them is the narrow corridor on the second floor, and the remaining five correspond to the room on the left side of the corridor.
But...what exactly did Mr. Ye want me to see?
Except for the vases in the room that are similar to the cabinet and the group at the end of the corridor, others such as the curtain and light trough on the ceiling, the wardrobe on the left side of the room, the grid-like floor tiles, and the somewhat thick door panel, I can’t see the fame at all…
Takagi She was very worried that he might get the wrong meaning because of his insufficient skills. After hesitating for a moment, he still shook his head, "Um...Mr. Ye, is there anything wrong with these things?"
"You didn't see anything?" Ye Gengyi rubbed his eyebrows, "You can recognize the things on it, right?"
"Recognize, recognize."
Takagi Wataru sweated...Is it an illusion? Why does it seem that the difficulty level suddenly dropped from exploring space to the level of kindergarteners looking at pictures and recognizing objects? ? ?
"That's good, I'll continue..."
Ye Gengdao: "The less light reflected from the surface of an object, the worse the ability of the naked eye to distinguish colors. For example, in the room in the photo, you first make it black and white, and then use it at an angle of 60°. Spatial association.”
He paused and asked, "How is it?"
"Uh, um, I..." Takagi Wataru's face was full of confusion.
Brainstorm? What should I do if I can't figure it out...
"Forget it, I said, you remember."
Ye Geng said:
"There is a mezzanine inside that seemingly thick door, and in the middle is a mirror that is almost the same size as the door. Because of the angle, you only need to lower the curtain to visually divide the room into a piece that is the same size as the corridor. Area……
In a dimly lit environment, through the reflection principle of mirrors, the curtain will be seen as a wall, and the wardrobe on the left side of the room will be seen as a database on the right side of the corridor. Of course, the most critical point is that this must be placed in advance. In front of the floor-to-ceiling windows…”
Ye Gengyi pointed to the cabinet and vase in the photo, "This can explain why the three of them did not see the body before the power outage."
"Oh, I get it!"
Takagi Wataru suddenly said, "In other words, the person who can use this technique is Mr. Xinghe who was in the corridor on the second floor at that time!"
