After talking off topic.

Meguru Thirteen began to reexamine the case in front of him:

"That is to say, the first person to find the body was Mr. Xinghe, Xiaolan and Heye, right?"

"Yes."

Starkawa Togo nodded:

"When we first arrived, there was nothing in the corridor. Because it was too dark, I pressed the switch of the light. As a result, even the light on the other side of the stairs was gone. After a while, when the call came, we saw Miss Zhanzi lying motionlessly in that place."

"The reason for the power outage has been confirmed just now."

Hattori Heiji walked to the wall and removed the false switch panel again. "Police Department, please find the forensic personnel to collect evidence directly. Someone tampered with it in this. As long as the power is closed, it will cause a short circuit."

"Ah,     Oh..."

Meguru Shisan leaned over to confirm the situation, turned around and was about to call Takagi Suk to go downstairs to call someone, but he was lost.

Where is the person?

"Mu Police Department, if you are looking for Officer Takagi, I just saw him being called away by Brother Gengyi." Conan said.

He actually considered whether to eavesdrop with him.

But then I thought about it and the crime scene was on the second floor. At most, they went to the first floor, which was to go to the yard and check the traces that the murderer might have left.

This kind of thing will be done easily after Officer Takagi comes back later.

Since the case cannot be solved so quickly, the most important thing is to listen to the confessions of several people first and supervise whether Xinghe Tong will have any evil actions towards Xiaolan.

...

The corridor in front of the bathroom on the first floor.

After Ye Gengyi called a gray suit police officer here, he directly told the conclusion of the murder.

"What?! The murderer is Hikka Tomogo?"

Takagi Shiro showed a surprised expression.

"Don't make a statement for now, now, this is what I just brought from the second floor room."

Ye Gengyi handed over Mrs. Zhengying's photo, "You arranged for the police to go to the convenience store nearby, which is about 10 to 20 minutes away, to ask, this woman has ever bought seasonings at around 7:30."

"oh."

Takagi took it honestly, ran to a policeman and muttered for a while, watching him go out with the photo, then ran back, scratched his head and guessed:

"Mr. Ye, do you suspect that Mrs. Zhengying is also a co-conspirator of Mr. Xinghe's killing Miss Zhanzi?"

"Well, she must know the loopholes in the proof of the absence of the Hsinkawa Tomogo. Since she has not been told, she is either accomplice or shelter. She will know after the investigation."

Ye Geng paused, signaled Takagisu to take out the account and ballpoint pen, and said step by step: "You have been to the second floor, so you should have noticed that the corridor there is very narrow, right?"

"Well, yes," Takagi agreed, "I feel that as soon as the door is opened, people will not be able to pass."

"The owner designed it on purpose," Ye Gengyi drew an angle in the air with his finger. "The door opens at about 60°, and the border of the door will reach the wall of the corridor, and it will also block the windows and cabinets at the end of the corridor."

"Cover?" Takagi Shiro captured the keyword.

"This is a photo I took with my mobile phone..." Ye Gengyi asked: "How is your spatial thinking ability?"

"Right, it's okay."

Takagi Shi was not sure what the criteria for this answer was, but he was an ordinary criminal policeman, so it would be better to be humble in front of Professor Ye Gengyi.

"Practice more when you're fine," Ye Gengyi said calmly: "After knowing your step length, you can go to a familiar place to observe the surrounding scenery first, then close your eyes and try to go to a designated place, and finally see how much deviation is."

“Uh…um…”

Shiro Takagi didn't know why, but suddenly felt like he was dreaming of going back to school, and was called to answer questions by the teacher in class, and then assigned homework after class.

...I've already started to be scared.

"How are the photos?" Ye Geng asked.

"Ah? I, I haven't seen it yet..." Takagi scratched his head.

Didn’t the two of them chat just now?

“…”

Ye Gengyi was silent for a moment, "Look at it slowly..."

For your own problems, you should not be anxious to chat with such people who cannot be distracted and used too much.

A few minutes passed in a flash.

Although Ye Gengyi still maintained that calm look without urging him, Takagi Shiro still felt great pressure.

There are only six photos on your phone in total.

One of them is the narrow corridor on the second floor, and the remaining five corresponding to the room on the left side of the corridor.

But...What did Mr. Ye ask me to see?

Except for the vases in the room that are similar to the cabinets and the group at the end of the corridor, the others are like the curtains and light troughs on the ceiling, the wardrobe on the left side of the room, the lattice floor tiles, and the somewhat thick door panel, which are completely incredible...

Takagi Shiro was very worried that he would be wrong because of his insufficient level. After hesitating for a moment, he shook his head, "That... Mr. Ye, is there any problem with these things?"

"You didn't see anything?" Ye Gengyi rubbed his eyebrows, "You always recognize the things on it?"

"Acknowledge, recognize."

Takagi sweated... Is it an illusion? Why did the difficulty coefficient suddenly drop from the exploration of space to the level of kindergarten reading pictures and identifying objects???

"That's good, I'll continue..."

Ye Gengyi said: "The less light reflected on the surface of an object, the worse the ability to distinguish colors with the naked eye. For example, in this room in a photo, you first add it to black and white color, and then perform spatial associations at an angle of 60°."

He paused and asked, "How is it?"

"Uh, that, I..." Takagi Shibu's face was full of entanglement.

Brain supplement? What should I do if I can’t make up for it…

"Forget it, I said, remember."

Ye Gengyi said:

"The thick-looking door has a mezzanine inside, and there is a mirror that is almost the same size as the door. Due to the angle problem, you only need to put down the curtain to visually divide the room into an area of ​​the same size as the corridor...

In a dimly lit environment, through the reflection principle of the mirror, the curtain will be seen as a wall, and the wardrobe on the left of the room will be seen as a database on the right side of the corridor. Of course, the most important point is that this must be placed in front of the floor-to-ceiling window..."

Ye Gengyi pointed to the cabinet and vase in the photo, "This will explain why the three of them did not see the body before the power outage."

"Oh! I understand!"

Takagi Suk suddenly realized, "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!"
Chapter completed!
