“Did you see the bathroom?”

“Opening the door.”

"...It's better when the phone can turn on videos. Just listening to you, I feel very anxious."

Chen Xing chuckled and shook his head, the sound on his phone was a little chattering.

Of course, the other end of the phone is Amuro.

When the case became confused and Chen Xing found that he could not see the most critical link because of his neglect. When everyone in the study seemed to have eliminated his suspicion, he called Anmu.

So everyone's explanations, including the investigation clues of Officer Meguri and others, were roughly heard.

Therefore, he proposed to go to the bathroom to have a happy look. Judging from his personality of Karuizawa's love of carpentry, he personally customizes and pastes it himself, maybe in addition to Karuizawa's villa and Osaka home, even the home in Tokyo is using the same tiles.

Toru Amuro doesn't believe in any ghosts. If the death message really exists, its strange disappearance must be caused by humans.

Therefore, the tiles that leave messages are the key to solving the case.

The commander of the Anshifu is in a distance, and I sincerely follow the instructions.

When I pushed open the bathroom door, I saw that I was covered with blue diamond tiles. The color seemed to change from top to bottom, and it was particularly dazzling after turning on the lights.

"How is it?" asked Tomoto Amuro.

Chen Xing was a little exhausted and didn't know how to describe it. He just roughly described the shape and color of the tiles, and then said: "The color has indeed gradually become lighter from top to bottom, but..."

"but?"

"Well, I always feel a little weird."

Chen Xing narrowed his eyes and looked at the tiles laid on the walls and floors, with blurred colors.

"So, take a photo for me." Toru Amuro said, and reported his email address.

Chen Xing hesitated for a moment, and sent him a photo with his email.

"So that's it." Soon, Tori Amuro chuckled.

"What did you see?" Chen Xing asked.

"You first find a way to pry a piece of ceramic tiles and compare them with other ceramic tiles on the wall. I'll explain it to you." Toru Amuro said.

Chen Xing raised his finger, and the sharp sword energy passed along the edge of the diamond, lifting the next page of the tiles. And the Amuro on the other side of the phone could only hear a subtle sound, not harsh, just like a thin wind blowing through the window frame.

He pinched a corner of the tiles and compared them with the tiles on the wall, slightly concentrating his eyes.

Tomoto Amuro asked: "Did you see it?"

"The overall color of the tiles is the same?" Chen Xing said unsure.

"It's the same." Toru Amuro said: "What you saw before was that the color of the tiles gradually became lighter from top to bottom, which was actually just an illusion of the eyes."

"Illusion?" The tiles were fiddled between Chen Xing's fingers. Even if they were just a small tiles, they could confuse people's eyes.

"This is called Shadow Diamond Trouble," Amuro Toro explained: "It means that the angles of each diamond are between 30 degrees and 40 degrees. Although only a little layer is used on the tiles, when people observe the color depth at the junction of this diamond, their eyes will naturally capture each point separately.

Because only looking at part of it, the overall visual effect of things is reflected visually, and the diamond on the top and the diamond on the bottom seem to have become other colors.

In other words, this is a phenomenon that the brain subconsciously produces calculation errors. The evidence is that the tiles in your hand are of the same color as the tiles on it."

Chen Xing listened silently and didn't say anything.

"Are you listening?" Amuro Tomo said in confusion.

"Listen."

"Then what?"

"What then?"

"Do you understand?" Amuroto couldn't help but say.

"..." Chen Xing questioned me?

"Since that's the case, the same design should be found in the bathroom of Karuizawa." He said: "The death message left by President Wakamatsu there is probably the murderer who used this method and replaced it with other ceramic tiles."

Therefore, this time, the blood reaction detection cannot be limited to the few tiles that President Ruomatsu wrote the blood words with his finger, but the entire bathroom.

Toru Amuro said in surprise: "I didn't expect you to think of this."

Chen Xing frowned, saying that I shouldn't have thought of it?

"Sure enough, as you talk more, you will be smarter than usual." Amuro said with a smile.

"I'll go and tell them to contact the police in Karuizawa." Chen Xing said, "I'm dead."

"Hey, wait." Amuro said subconsciously.

At this moment, Chen Xing's eyes moved and he looked at the bathroom door.

As the footsteps approached, there was still the sound of people talking.

"Strange, I remember that the lights were mentioned here before." It was the female butler, Shiko Yorihara.

"Maybe someone came here to go to the bathroom just now." Hattori Heiji said.

"Is it possible that guy?" Conan said suspiciously.

As he was talking, Chen Xing took the initiative to open the door and walked out.

"Chen Xing? Why are you here?" Iron Triangle met and was a little surprised.

"Find a bathroom." Chen Xing smiled.

Conan tilted his head, thinking of his actions just now, although he just casually put his hand behind him, if he read it correctly, the phone screen seemed to be in a call state?

"Who are you calling just now?" Conan said curiously.

"Yes, the staff in the store reported to me about tomorrow's dessert list." Chen Xing said as if nothing had happened: "Are you looking for a bathroom?"

"No, no." Yorihara Saki hurriedly said, "It's them who want to take a look at the bathroom."

"The bathrooms in Karuizawa Villa are all made of the same ceramic tiles." Conan said: "We just asked the Yamato Police Officer who was investigating Karuizawa. If there is any clue, we will notify us."

"Go in and have a look first." Hattori Heiji said casually, walking into the bathroom, "Tiyao, did you see anything just now?"

"I saw the tiles." Chen Xing said.

"What?" Hattori Heiji said, turning his head to see the tiles all over the place, and his face suddenly changed.

"Oh, I'll say." He frowned.

"Well, that's right, crazy   diamond." Conan whispered.

Next to him, Chen Xing looked expressionless and suddenly spoke English or something, which was indeed a bit difficult.

Fortunately, Mihara Saki didn't understand either, so he asked immediately.

Hattori Heiji's explanation is roughly the same as Tomori Amuro said, and finally said: "That is, this is an illusion of the eyes."

Mihara Shizuko understood it, but she didn't quite understand it.

Chen Xing could vaguely hear the laughter on the phone.

"The phone with Sister Ye is ringing." Conan pointed to Hattori Heiji's pocket.

"Is it a detective boy from Osaka?" After the call was connected, a rough and bold voice came faintly.

"This voice, are you Yamato Police Officer?" Hattori Heiji asked.

"Just just now, we found the pre-death message of the murdered President Wakamatsu." Yamato Kensuke said: "The text is three English letters, son."

"son?" Hattori Heiji and Conan looked at each other.

‘Son’?

"Yes, if this case is done the same as your case, you should arrest the president's son soon, and he might be the murderer!" Yamato Kansuke said.

"This is difficult." Hattori Heiji whispered.

"What's wrong?"

"Because the person who was killed here tonight is the son of the president."
