Finished talking off topic.

Mu Mu Shisan began to re-examine the case in front of him:

"In other words, the first person to discover the body was Mr. Xinghe, Xiaolan and He Ye, right?"

"Yes."

Xinghe Tongwu nodded:

"When we first came, there was nothing in the corridor, because it was too dark, so I turned on the light switch, and as a result, even the lights on the stairs went out. After a while, when the call came, we I saw Miss Zhanzi lying there motionless."

"As for the cause of the power outage, Brother Geng has just confirmed it."

Hattori Heiji walked to the wall and removed the cover switch panel again, "Police, please ask forensics personnel to come and collect evidence directly. Someone has moved in here, and as long as the power is turned on, it will cause a short circuit."

"Ah, oh..."

Mu Mu Shisan leaned over to confirm the situation, turned his head and was about to greet Takagi Shibu to go downstairs to call someone, but he was in vain.

What about people?

"Muki Police Department, if you are looking for Officer Takagi, I just saw him being called away by brother Genichi." Conan said.

In fact, he also considered whether to eavesdrop on the past.

But on second thought, the scene of the crime was on the second floor, and when they went to the first floor, they would go to the yard and the surroundings to check the possible traces left by the murderer.

After the police officer Takagi comes back later, he can do this kind of thing at will.

Since the case cannot be solved so quickly, comparing the two, listening to the confessions of a few people first, and monitoring whether Xinghe Tongwu will do anything wrong with Xiaolan is the most important thing at the moment.

...

Corridor 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?"

Shibu Takagi showed a surprised expression.

"Don't make a statement, now, I just took it from the room on the second floor."

Ye Gengyi handed over the photo of Mrs. Zhengying, "You arrange for the police officer to go to a nearby convenience store with a round-trip journey of about 10 to 20 minutes and ask if this woman has gone to buy condiments around 7:30. "

"Oh."

Takagi Shibu honestly took it, ran to a police officer and muttered for a while, and after watching the other party go out with the photo, he ran back again, scratching his head and guessing:

"Mr. Ye, do you suspect that Mrs. Zhengying is also an accomplice of Mr. Xinghe in killing Miss Zhanzi?"

"Well, she must know the loophole in Xinghe Tongwu's alibi. Since she didn't say it, it was either an accomplice or a cover-up. After the investigation, she will know."

Ye Geng paused, motioned Takagi Shibu to take out his wallet and ballpoint pen, and said step by step, "You have been to the second floor too, you should have noticed that the corridor over there is very narrow, right?"

"Well, yes," Takagi Shibu agreed, "it feels like as soon as the door is opened, people can't get through."

"The owner deliberately designed it this way," Ye Genyi drew an angle in the air with his fingers, "The door is about 60° when the door is opened, and the frame of the door will touch the wall of the corridor, and it will also block the corridor. Windows and cabinets at the end."

"Block it?" Takagi Shibu caught the key word.

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

"Alright, it's okay."

Takagi Shibuya didn't know what the standard for this answer was, but he was an ordinary criminal policeman, so it would be better to be humble in front of Professor Ye Genyi.

"Practice more when you have nothing to do," Ye Geng said calmly: "After knowing your stride length, you can go to a familiar place to observe the surrounding scenery, then close your eyes and try to go to a designated place, and finally see to the end. How much deviation."

"Uh... um..."

Takagi Shibu didn't know why, but suddenly he had a dream of going back to school, being called up by the teacher to answer questions in class, and then being assigned homework.

...is already starting to get scared.

"How does the photo look?" Ye Geng asked.

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

Didn't the two of them chat just now?

"..."

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

As for your own problems, you really shouldn't be in a hurry to chat with someone who can't be distracted and multitask.

A few minutes passed by.

Although Ye Genichi still maintained his calm appearance and did not urge, Takagi Shibu still felt a lot of 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 did Mr. Ye want me to see?

Except the vase in the room is similar to the cabinet and the group at the end of the corridor, other such as the curtain and light trough on the ceiling, the wardrobe on the left side of the room, the lattice-like floor tiles, and the somewhat thick door panel, Can't see the hall of fame at all...

Takagi Shibu was very worried that he would be wrong because of his lack of skill, he hesitated for a moment and then shook his head, "That... Mr. Ye, is there anything wrong with these things?"

"You didn't see anything?" Ye Geng rubbed his eyebrows, "You know what's on it, right?"

"Recognize, recognize."

Shibu Takagi sweated...is that an illusion? Why does it feel that the difficulty factor has suddenly dropped from the exploration of space to the level of reading pictures and objects in kindergartens? ? ?

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

Ye Gengdao: "The less light reflected on the surface of the object, the worse the ability of the naked eye to distinguish colors. For example, in this room in the photo, you first fill it with black and white colors, and then use an included angle of 60°. Spatial associations."

He paused and asked, "How is it?"

"Uh~lightnovelpub.net~ That, I..." Takagi Shibu was tangled.

Brain supplement? Can't figure out what to do...

"Forget it, I said, you remember."

Ye Geng said:

"The thick-looking door has a mezzanine in it, and in the middle is a mirror that is almost the same size as the door. Because of the angle, just put the curtain down to visually divide the room into a piece the size of the corridor. Area……

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

Ye Geng pointed to the cabinets and vases in the photo, "This can explain why the three of them didn't see the body before the power outage."

"Oh, I get it!"

Takagi Shibu 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!"
