Detective Conan: Twelve Death Warlocks

Except for the windows and the wall near the corridor, there are no bookshelves at the scene. The desk is inside. In other words, whether the victim goes out or comes in, he will pass through the transom. There is no doubt about this. And near the corridor

The place is a fish tank, in

There is a small coffee table in the middle of the floor, with a model of a cradle on it, but Conan knows this model because there is a plastic trapeze figure hanging on it, which can swing like a swing. Back in the department store,

The three children also bought this toy.

But he didn't dismantle it, because he didn't know the specific structure. Maybe it was because Mr. Natsume's granddaughter liked this toy, so she left it here accidentally and didn't take it away!

Conan drank Coke and glanced sideways at Mr. Natsume's house where two policemen were guarding the door, his expression gradually becoming serious.

After he finished a can of drink and found the trash can and was about to throw it away, he suddenly saw a young middle school student in the park doing various difficult moves with a yo-yo in his hand. Conan was stunned for a moment, but

Soon, a faint smile appeared on the corner of his mouth.

Conan called Mitsuhiko and asked about toy design: "Excuse me, does the top design of your trapeze have a design similar to a bearing?"

"Bearings? Are you talking about the kind of bearings in bicycles?"

"right."

"It doesn't seem to exist, but why do you ask this question?"

Conan lied and said to Mitsuhiko: "Actually, I'm more curious. After all, no one of you has opened it before, so I just asked."

Mitsuhiko seemed to think that Conan would like the trapeze model to be more fun, so he joked: "Who told you not to buy it with us at the time? Are you envious now?"

Conan sneered, with a slightly embarrassed expression. Who wants to play with that kind of thing? If it wasn't to solve a case, why would he call you, a brat who knows a little bit? When he entered Natsume's house again, he heard

Megure Thirteen sighed, and Mouri Kogoro was also a little irritable. Seeing this, Conan was helpless, so he hid in the corner and shot Moori Kogoro with his tranquilizer gun.

Seeing Mouri Kogoro doing "Drunken Boxing", Megure Thirteen quickly helped him up, let him sit on the sofa, and said with some annoyance: "Oh, Brother Mouri, you are such a reasoning person.

, it catches me off guard every time, and I have always been worried about it, for fear that you might not step firmly and hit a sharp corner."

"Officer Megure, I'm fine. Regarding the case in front of me, I already know the methods used by the murderer and who the murderer is."

Mu Mu Shisan's eyes lit up, but then he became a little unhappy: "It turns out that your serious face before was just an act!"

"Hahaha, no. Actually, it was because I just suddenly thought of the All-Japan Yo-Yo Competition that will be held by Nippon TV Station recently, so I was inspired to think about the entire contents of the case. And the reason why the police did not think of this key point

, because it is easy for us to ignore the inspiration from toy design.”

"Toy design?" Megure Thirteen was a little surprised, not knowing what Mouri Kogoro wanted to say.

Sakuramiya Miwako was obviously a little surprised. She seemed to know something, so she said to them: "In fact, from the production structure, yo-yos are divided into three types: integral type, bearing type and clutch type. The integrity is throwing the yo-yo

When the ball reaches the lowest part, it will bounce back immediately; the bearing-type yo-yo can be detached as a whole.

When the rope is put on the bearing, it can idle for a long time; it can realize the automatic return of the Yoyo. This is a clutch that uses the centrifugal force of the Yoyo. When rotating at high speed, the metal ball is acted upon by the centrifugal force, causing the clutch to open and become an idling state, slowing down.

When the spring force is greater than the centrifugal force, the clutch is closed and the bearing is fixed."

"Yes, what this police lady said is absolutely correct, and the core of this case is actually the bearing."

"Bearing?" Megure Thirteen was very surprised by this and looked at Mouri Kogoro, "Moori brother, what method did the murderer use to make everything disappear without a trace?"

"Hey, Officer Megure, I just asked Conan to investigate this. Police lady, how is your shooting skill? I know the shooting of Officer Takagi and Megure, maybe a large area could be accidentally injured.

"

Miwako Sakuramiya understood somewhat: "I have no problem, but Mr. Mori, what should I do?"

"Conan, then take Miss Sakuramiya to Mr. Matsushita's room across the street, use the toy crossbow you just bought, and be ready to try to complete the technique."

"Yes, Uncle Maori." Conan suddenly appeared next to everyone, startling everyone.

When passing by Kogoro Moori, Conan put the loudspeaker in his jacket pocket. Then he took out a piece of equipment with a small plastic ball tied to the front end and handed it to Miwako Sakuramiya. This is an automatic

Shooting the crossbow, Conan looked at Sakuramiya Miwako and said to her: "You can see in front of you, there is a device with a trapeze toy tied to it! Just shoot it and shoot it.

Maybe don’t miss it.”

"good."

When I heard the loudspeaker sound, the string tied with the ball flew out. Because it was a toy crossbow, the ball didn't fly out very fast. You can clearly see the ball flying in, but...

Not long after the ball flew over the toy, I saw that the ball seemed to be hooked by something, and it stopped suddenly. Then the ball fell with the rope, and because of the power, it circled around it several times.

.

They were very surprised by this. At this time, Sakuramiya Miwako picked up the walkie-talkie and reported: "Because Conan tied a knot on the nail set here on the window before, so it was completely pulled."

Conan immediately ordered her to cut the rope with scissors, then put the thing on and lift it up.

"Because this is the second floor, and with the lift, the dynamic potential energy will be greatly increased. In other words, as long as he can wait for the victim to arrive there at the right time, he can slide the hook down."

Everyone gasped as they watched the heavy object slide down.

"Then tie the opening from that side, tie a knot, pull hard, and then relax the hanging thread in your hand, and the thread will be completely retracted due to natural rotation. And the thread that was previously entangled by the weight will also

It falls due to the release of direction, creating the illusion of a hanging part."
