The glass is the best artifact with ears on the partition wall, and it often appears in speculative dramas.

As long as you use a glass, buckle it upside down on the wall, and put your ear on the base of the glass to listen, you can use the resonance of the air to gather the sound at the bottom of the cup through the bucket-shaped glass, and reduce the spread of sound, so you can hear the sound next door.

Of course, if the walls are soundproofed or too thick, sorry.

However, in the world of science here, as long as the principle is enough to learn it, everything is possible.

For example, now, Rabbit Chuan and Mao Lilan are holding two glasses, and the sound in the door is clearly heard, and the effect is no worse than Conan's bug.

Unlike Mao Lilan's imagination, a man and a woman in the door are not ambiguous, but a bit tense.

Because they heard Maori Kogoro say, "Ah, yes, I'm trying to persuade people to turn themselves in." "

Conan is anxious, bad, uncle really got it wrong!

But I didn't expect Maori Kogoro to actually say next: "However, I am not trying to persuade you to turn yourself in, but Mr. Nagumo Xiao, who is protected by you." "

Huh?" Conan couldn't believe his ears, his uncle was actually right this time!

"What are you doing?" Rabbit Chuan knocked on Conan's brain, but fortunately Mao Lilan's attention was focused on the door.

Conan shrunk his neck, shut up and continued to eavesdrop.

Inside the door, Yucheng Liuli strongly retorted: "What are you talking about?" Why should I protect Mr. Nagumo? Maori

Kogoro asked rhetorically, "Did you see that?" Before you noticed the snow, when we were in the hallway, didn't we happen to meet the staff coming out the door?

"You were surprised because you saw the glass of that door reflect the way Mr. Nagumo came out of Kazami-san's room and almost bumped into the staff and panicked and hid back in the room."

"You guessed that he might have done something bad to get him out of the room smoothly, so you asked everyone to go out to enjoy the snow."

"Then, while everyone was outside enjoying the snow, you secretly returned to Kazami Yoshiki's room, found Kazami's body, and screamed loudly."

Maori Kogoro suddenly discovered this when he saw Conan's figure on the door glass.

"Dad is so good!" Maori Lan outside the door was excited.

Rabbit Chuan also heard the reasoning of the living Maori Kogoro for the first time, and it felt that it was indeed different from the old brother, and there was a very stable feeling.

"It's worthy of being a detective..." Yucheng Liuli smiled slightly, "However, before you fabricate that I am a witness out of thin air, let's explain how the blade that cut Kazami's neck by about 10 centimeters disappeared, right?"

Conan pinched his uncle at the door.

Maori Kogoro let out a long sigh: "Ah... Everyone was deceived by the 10-centimeter wound, so they couldn't imagine that the murder weapon was just a 2-centimeter piece of iron. "

Huh?" Yucheng Liuli was stunned for a moment.

Maori Kogoro said: "The murder weapon was a utility knife, and after the murderer, he broke the blades piece by piece and folded them, and then hid them ... In Kazami-san's lighter. "

Conan was pleasantly surprised, uncle is so powerful today, everything is right.

Rabbit Chuan was also surprised, could it be that Uncle Maori knew that Conan had used up the anesthesia needle, so he worked so hard?

However, the clues are all dancing in front of Uncle Maori and the kind of face, even if you don't know the truth, it's difficult!

However, Yucheng Liuli did not stop there, and said unhurriedly: "Even if there is a blood-stained blade hidden in the lighter, is it really a murder weapon?"

"The deceased's wound was 10 centimeters, which means that the knife was deeply stabbed and could not have been done without the hilt, but the police did not detect the luminol reaction on the handle of the utility knife."

The Rabbit River outside the door was waiting for Maori Kogoro to refute her fiercely, but I didn't expect that Maori Kogoro didn't expect that he was suddenly taken away by Yucheng Ruri.

Conan was in a hurry and shouted outside the door: "Brother Rabbitchuan, did you bring chewing gum?"

"Yes, yes, yes." Because Rabbit River sometimes gets motion sickness, he often picks up some mint-flavored chewing gum when riding in the car.

Sure enough, Maori Kogoro in the door received a prompt from Conan: "By the way, it's duct tape!" Just wrap tape around the handle of the utility knife so that the handle does not get bloody.

"Then, he wiped off the blood on the tape and stuck it to the floor on the shooting site, because the shooting scene was full of tape, and no one would care if there were a few more."

Yucheng Liuli seemed to be flustered: "But, but why must Mr. Nagumo do it?" I can do this kind of thing!

Maori Kogoro said in a very sincere tone: "What are you talking about, how can you kill people?" "

How can a beautiful woman kill?

Rabbit Chuan's teeth are sour, this reason... Worthy of being a Maori uncle!
