The next day, when the kidnappers told Ayumi's parents, who had calmed down, about the ransom of 12.1 million yen, Chiba had already asked the school authorities for three days off and was stepping on the spot - finding a suitable ambush spot for the police snipers.

The note that Chiba handed to the Administrator contained all of Chiha's inferences and suggestions, including a presumption of where the hostages would be saved. These judgments and recommendations were approved by the Twilight Police Department, and after considering how much of the risk of exposure would be caused by the police investigating on their own (in case the kidnappers also came to step on the spot, how to break it), Twilight chose to send Chiba to find a suitable attack point in the area.

The Twilight Police Department gave Chiba a simple request to find an attack point, as long as any of the following conditions were met.

1. You can see the crosswalk on the side of the road where the corpse is thrown at the theoretical point.

2. Be able to see the crosswalk on either side of the two roads connected by the entire road at the theoretical point of throwing the body.

But Qianyu knows very well that there are many places where it can't be a good sniper point.

First of all, it is definitely not possible to go too high, sniping in this kind of place is fired from above, and the slightest mistake will hurt Ayumi who is likely to be carried by the kidnappers on his shoulder.

Secondly, it is best to have a small store with fewer people, otherwise it is easy to have an accident if there are too many people.

In addition, there are some taboos for sniper selection that cannot be counted one by one, so there are not many ideal points that Qian Yu can choose.

After four hours of surveying, Chiba returned to the Metropolitan Police Department with 4 excellent points and 13 working sniper points.

"Conan?" Chiba actually took a picture with Conan at the desk of the Twilight Police Department. "Why are you here?"

"You've been meticulous in your excavation of the dossier," Conan said, waving the notebook in his hand. "But it's not detailed enough."

"Oh?" Chiba handed the notebook to the Twilight Police Department and asked Conan curiously. "Tell me."

"You deduced that the kidnappers carried the girl to the dumping site on foot, right?"

"That's right, because it's hard to carry a 20-kilogram unconscious girl on a bicycle or something."

"It's more than that," Conan added. "There's a photo taken by the first discoverer (a journalist) that you may not have noticed, but not far from the dumping site there is a muddy puddle where faint wet footprints appear. The direction of this footprint is the opposite direction of the reporter's house, so it is not the footprint of the journalist himself. The footprints would have dried out completely in more than 10 minutes under the current weather, so they should have appeared around the time of the killing of the girl. If it was someone else's footprints, surely the kidnapper could have been seen and noticed his abnormality, how could it not have appeared when the police were openly looking for witnesses? So this can only be the footprints of the kidnappers themselves. ”

"Okay... But I think it's a 90% chance of being correct. Qian Yu shrugged his shoulders and said.

"90% is enough," Conan said. "We're not arresting criminals looking for evidence now, our purpose is to save people, and if we can find the answer within two days, it doesn't matter how many times we make mistakes."

"That's right, go ahead."

"In the morning, I performed an autopsy on the third body found yesterday, examining the part that the forensic doctor had neglected," Chiba opened his notebook and showed the conclusion directly to Chiba. "Although the first two bodies have been retrieved and cannot be examined, this one has already provided a lot of information."

"Silica fume?" After reading it, Qian Yu said in surprise. "In the hair of the third corpse?"

"Yes," Conan said, closing his notebook. "The kidnappers' kidnapping site isn't too far from a few dumping sites, right? The area near the dumping site is a residential area, and there are not many places with silica powder, right? ”

"The semiconductor industry or the alloy industry and related warehouses," Chiha's tone was clear. "There's only one rice flower!"

"Yes, just southwest of the place where Ayumi was kidnapped, there is a semiconductor warehouse, and Ayumi is likely to be there." After Conan finished speaking, he curled the corners of his mouth and looked at Qianyu. "What do you think?"

"So what's next? Let's get to the bottom of it first? ”

"Why not?" The corners of Conan's mouth drew an arc.

。。。

"Still, your reasoning is really good," Chiba said as she walked along the road. "It's also very observant."

"Huh? Oh, in fact, these are all taught to me by my brother Shinichi~" Conan was taken aback, then scratched his head and said tenderly.

“。。。” Qianyu's brow jumped. "This guy ... Why did the painting style suddenly become this ghost virtue? ”

Intuition tells Chiba that Conan's explanation is greasy, and as for what catty is, Chiba doesn't know.

"It's here," Conan's words pulled Chiba out of his thoughts, only to see an old warehouse appear in front of the two of them.

"The door is closed, let's see if there are any windows." Qian Yu took the Traceless Umbrella in his hand and said.

"Hmm." Conan turned on the transmitter of the anesthetic watch and responded. "Follow me."

"I'll take the lead," Qianyu shook the Traceless umbrella. "I'm melee."

Chiba and Conan walked around to the back of the warehouse, and sure enough, they found a small open window that could accommodate children like Chiba and Conan. However, the small window is a little more than two meters above the ground, making it difficult to climb up.

"Conan," Chiba crouched under the window. "Stand up, go in and have a look."

"Huh? Oh, okay. Conan paused for a moment, then reacted and ran over, putting his feet on Chiba's shoulders.

"Hold it up." After Qian Yu finished speaking, he slowly got up. When Chiba stood up, Conan reached for the lower edge of the window, and Conan climbed onto the window with both hands.

"It's a toilet, there's no one in it." Conan glanced at it and said.

"Don't go in, you can't get out." Qian Yu frowned and suggested.

"I can come out," Conan said, leaning on the window, reaching out to Chiba. "You hand me the tip of the umbrella."

"Huh?" Qian Yu was slightly stunned, and then did so.

"Jump up!" Conan snorted. Hearing this, Qian Yu immediately jumped up, and Conan took advantage of the situation to pull the umbrella, which was already the height of a window, into the window and made it a lever. At one end is Conan who jumped from the window, and at the other end is Chiba outside the window.

"It's also up to you... Qian Yu grabbed the handle of the umbrella with one hand, and the corners of his mouth twitched. "It's up to you to come up with this method."

"Hold on to your hands!" Conan said, holding the umbrella closer to the tip. The lever that was originally balanced tilted towards Conan's side, and Qian Yu also took advantage of the situation to pick up the window and rolled in.

Qian Yu was about to say something, but saw Conan looking intently listening to something. And when Qian Yu listened to himself, he smiled slightly and looked at Conan, who was also smiling.

In this closed warehouse, there is actually the sound of a TV!

"Got you!" Conan and Chiba said in their hearts at the same time. "Mr. Kidnapper!"
