Days mixed in the world of Conan

“Then again, at such a critical moment, where did this Kudo Shinichi run?” Officer Twilight complained as he looked at Conan on the hospital bed.

“It is likely that I ran away because I was afraid of the challenge of the prisoner.” Yeyi analyzed seriously, “Otherwise, if he would have appeared long ago, this shows that Uncle Maori is better than him.” ”

“That’s right, ahahahah,” Maori Kogoro laughed happily.

“You fellow,” Conan looked at the night resentfully.

At this time, the phone that Conan had placed on the table suddenly rang.

Conan was about to pick up Maori Kogoro stopped and said, “Wait Conan, pay attention, if it is a prisoner, give me the phone immediately.” ”

Conan nodded and picked up.

“I didn’t think you would find that bomb, and it deserves a reward.” The voice that came from the earpiece after the voice change was indeed from the prisoner, “But the child’s playtime is over, call Kudo Shinichi out for me.” ”

Conan looked at Maori Kogoro and nodded again, Maori Kogoro took the phone, pressed the hands-free button and said: “That’s right, it’s adult time now.” ”

“Who are you? What about Shinichi Kudo? A voice that was not Conan on the phone asked strangely.

“Kudo Shinichi is not here, it is enough for me to deal with you. Listen, I’m Detective Maori Kogoro. Maori Kogoro straightened his collar and said.

“Hmph, that’s fine.” The prisoner on the phone sneered a few times, “But I only said once, I heard clearly, I installed five bombs on the Dongdu Ring Line.” ”

Everyone was shocked to hear this, and Maori Kogoro’s fully tied hand almost strangled himself.

“The bomb started after 4 p.m. today, and if the train traveling above was traveling at less than 60 kilometers per hour, the bomb would have exploded. In addition, the bomb can explode without defusing before the sun goes down. This time I’ll just give you a hint, I put those five bombs in the ‘XXX of the Dongdu Roundabout, where each X represents a word. So come on, Maori Detective. The bomber finished speaking and hung up.

“I guess he’s joking, right?” Maori Kogoro secretly wiped his sweat and said, “How can there be a bomb on the ring line?” ”

“No, he’s serious. I’m afraid he has already set up the bomb and will explode as soon as 4 p.m. arrives. Officer Twilight said solemnly, “Anyway, I have to contact the headquarters immediately.” ”

……

After giving the order, Officer Twilight received a reply and said with relief: “Don’t worry, so far there is no detonated train. ”

“I see, Officer Twilight.” Maori Kogoro said suddenly, “When the prisoner says ‘XXX’, it means ‘under the seat’ or ‘above the shelf.'” ”

“So, ‘underbody’?” Officer Twilight looked at Kogoro and said.

“Uh…” said Maori Kogoro for a moment.

“No way, you forgot that the prisoner gave a detonation condition, the speed of the car.” If this thing is detonated manually, the prisoner must have a speed measurement and then let him receive the measured speed and detonate. If it is automatically detonated, how can the speed of the car be measured above the rack or under the seat or under the body? Yoruya retorted. This is not the era of GPS positioning popularization later, and even mobile phones are where to get high-tech. ”

“Makes sense, where would that be?” The crowd couldn’t help but fall into deep thought.

“By the way, Ayumi and the three of them went home, and the train they took should be the Dongdu Ring Line.” Dr. Agasa said suddenly.

Conan heard this, and just wanted to take out the detective armband to ask where they were, but was stopped by Night.

“It’s useless, if they hadn’t got on the bus, they wouldn’t have been able to get on it later, and now all the loops don’t stop.” What do you say if they go up? Tell them there is a bomb? And then they launched the style of the juvenile detective corps to find it themselves? ”

“Well, okay.”

Officer Megumi then takes Mori Kogoro to the command room of the Toto Railway, leaving Conan and Yoru and Dr. Agasa.

“Again, the location of the bomb must be a place where the speed of the train can be measured, and where on the train can the speed be measured?” Night followed Conan and analyzed.

“It seems that there is only a speedometer, but even if you put a bomb on it in that place, it will not affect the bomb.” Conan said suspiciously.

“You forgot a way, what does the speed measurement rely on, what is the speed of the car, it is the distance traveled by the train per second, time can be measured, so what about the distance.” Night said.

“Measuring distance?”

“Shadow, the shadow of the train, use the shadow of the train to cover the time that the bomb has passed, and measure the speed of the car.” Night spoke the answer. “It’s no wonder you can’t remember it at the first time, you haven’t experienced the problems of the Bob series, and you definitely can’t associate it at the first time.” I think of the fear of being dominated by Xiaoming in the first place. ”

“So it is, it’s solar energy, and the bomb is between the rails.” Conan finally figured it out, and then quickly took out his mobile phone and called Officer Twilight in Kudo’s voice.

“Police Department, I’m Shinichi Kudo, and I’ve listened to Dr. Agasa about everything. The real location of the bomb is not under the seat, nor above the shelf, nor under the body. The correct location should be between the rails. Conan said.

“Between the tracks?”

“Yes, the five bombs had been designed by the criminals, and those bombs would explode if they didn’t get sunlight for a while, and if the train on the ring line passed above the bomb, the light would be blocked for a few seconds. If a carriage is calculated at 20 meters, ten carriages are 200 meters. At a speed of 60 kilometers per hour, the second speed is equivalent to 16.7 meters, which means that it takes about 12 seconds for the train to travel 200 meters. And the buffer time of the bomb should be the event of the train passing two hundred meters. Because of this, the train is now immediately transferred to other tracks, and as long as the train is out of the loop, there is no danger of stopping. Conan explained.

“I see.” Officer Twilight said solemnly, then hung up the phone and said to the train chief; “Director Sakaguchi, I think you should have heard it all.”

Director Sakaguchi nodded, and then immediately arranged it.

……

“All five bombs have been recovered.” Officer Twilight said to the crowd, “This time thanks to Kudo Shinichi’s reasoning.” However, the charge of these bombs is only a quarter of what was stolen from the Toyo powder magazine. ”

“So, three-quarters of the gunpowder is still in the hands of the prisoners.” Maori Kogoro touched his chin.

“Sorry, I’m late,” Officer Shiratori trotted in.

“Tell me quickly, how is the investigation?”

“Yes, I have investigated Kohei Okamoto, the son of Chief Okamoto, and I have determined that he left Tokyo for Izu this morning.” Officer Shiratori said, holding his notebook.

“So, it has nothing to do with him,” Officer Twilight mused.

Then Maori Kogoro began his wonderful method of elimination reasoning, saying: “It is very likely that he lived in the apartment where the bomb in the pet pen stopped, and he stopped the timer for fear that the bomb would explode and hurt him.” ”

Officer Twilight felt that it made sense and immediately set out to investigate. _
