Soon, it was detected that the bottom of the secret room was empty, with two pressing machines inside, and the others were unknown.

One is that if the person entering the secret room weighs more than a certain level, the floor will sink.

The other is the bottle in the center of the floor. As long as there is a change in pressure, the floor will sink.

"Let Conan go." Yamazaki suggested, "with his weight, you can easily pull him with a rope."

Lan asked, "Is that OK? Conan?"

Conan replied: "No problem, Sister Lan."

Haibara curled her lips, isn’t this quite capable of pretending to be young...

Use iron rods to form a bracket, and one end of the rope is wrapped around your waist and the other end is grabbed. In this way, if Conan triggers the mechanism, Conan can temporarily hang in the air and not fall down, and then pull him back.

Conan boldly walked to the glass bottle, facing the exit, and tried to pick it up, but it didn't hold it, and it didn't turn.

Conan said: "I can't pick up the bottle, I'll open the lid."

"Wait," said Nobuke Oda, "we don't know how sensitive this device is, so it's going to be fast."

"Yes." Conan responded.

Ran, Yuan, Ayumi, and Mitsuhiko all asked Conan to be careful and cheer for Conan.

"Don't talk, let Conan concentrate."

Maori spoke, calming Lan and others down, looking at Conan with a worried breath.

Conan took a breath, pulled out the bottle plug, and took out the black object inside. The floor at the foot of the floor immediately flipped, and a large area of ​​dust rose, blocking his sight for a while.

"ah!"

"Conan!"

Conan was pulled up amid Conan's surprise and the exclamations of Lan and others.

The dust fell to the ground, and everyone laughed when they saw Conan holding the black object hanging on the bracket with a little dirt-faced look.

Putting down Conan, Conan handed over the black object to Oda Nobue.

Unlocking the rope, Lan wiped Conan with a handkerchief.

Seeing Conan's face as if he was enjoying himself, Yamazaki and Haibara were speechless.

The black object was quickly confirmed, a piece of black crystal.
