Conan: Another Famous Detective

Conan took out his mobile phone with a solemn expression.

"Is it a call from a prisoner?" Officer Memu's voice deepened.

"Yes, what awaits us next is probably one or even more bombs that are urgently needed to be found!" Conan's voice was solemn, and he consciously handed the phone to Hanomiya Akira.

Yu Gongming took the phone and pressed answer and speakerphone.

"Hey! Detective, are you ready to accept the challenge of the next round?" It was still the same voice disguised by a voice changer, with a hint of expectation in his mocking tone.

"Tell me, where did you install the bomb?" Yu Gongming didn't want to talk nonsense with him and went straight to the point.

"Haha, it seems that Detective Hanomiya is also eager to try..." The other party sneered:

"Then listen carefully, I will only say this once. I have installed a total of five time bombs on the Dongdu Circular Line..."

When Officer Memu heard this, his expression suddenly changed!

"The bomb will be officially activated after four o'clock in the afternoon. If the train travels at a speed lower than 60 kilometers, the bomb will explode. If you cannot find the bomb before the sun sets, the bomb will also explode..."

"How about it, detective, do you feel the pressure? After all, the lives of hundreds of people are involved, hahahaha!"

Officer Memu's face became increasingly ugly. Hearing the wild laughter coming from the other end of the phone, he couldn't help but clenched his fists.

There was no change in Yu Gongming's expression, and he said calmly: "I do feel a lot of pressure. Why don't you give me some hints about the location of the bomb?"

"Haha, the reminder was given just now. With Detective Hanomiya's ability, I think this is enough. So, I'm looking forward to your performance, hahahaha!"

After another burst of laughter, the other party hung up the phone.

"You're crazy! You're laughing at your sister's smile. Why are you so good at your age?" Yu Gongming cursed in his heart.

After glancing at the time on his phone, he said to everyone:

"Unfortunately, there's less than five minutes left until 4 p.m."

Officer Megure took a deep breath and said seriously: "I will immediately notify the circular line to keep all trains at a speed of more than 60 kilometers per hour!"

With that said, Officer Megure immediately picked up the landline phone at work and started speed dialing.

…………

Dongdu Railway Command Room.

"What? A bomb was installed on the Dongdu Ring Line!?" the commander said in shock.

"Yes, the Metropolitan Police Department has already called. It's absolutely correct!" Railway Communications Minister Sakaguchi said solemnly.

"Understood, we will stop all trains immediately for inspection!" the commander said.

"No, the bomb will be activated at four o'clock. Once the speed of a train is less than 60 kilometers per hour, the bomb will explode!" Minister Sakaguchi shook his head.

Perhaps Minister Sakaguchi was too excited and failed to control the volume, causing the entire command room to hear this sentence.

"What? Bomb!?"

"On the ring line!?"

"Start after four o'clock... Wow! It's less than three minutes until four o'clock!"

Minister Sakaguchi looked at the somewhat chaotic command room in front of him, frowned, and shouted:

"Quiet, everyone!"

After everyone heard this loud shout, their habitual obedience to their superiors made them immediately quiet down.

"Notice further, all trains running on the circular line must maintain a speed of 60... No, all trains must maintain a speed of 70 kilometers per hour!"

"Those trains that are about to arrive at the station..."

"Just pass the station!"

"Those trains still in the station..."

"Depart immediately and maintain a speed of 70 kilometers per hour! In short, all trains must maintain this speed until the bomb is found. Please notify us quickly!" Minister Sakaguchi shouted anxiously.

"Yes!" The commander hurriedly rolled to the command platform and issued the order!

"Attention all trains, according to reliable information..."

…………

Officer Memu frowned and walked back and forth in the office.

"Damn it, why is there no news over there yet!"

Ring ring ring!

The landline phone on the desk rang!

Officer Megure immediately rushed to the phone and answered the call.

"Hey! I'm Megure...how's the situation? Oh, okay, we will find the bomb as soon as possible!"

Officer Memu hung up the phone and looked a little more relaxed:

"Fortunately, no bomb has detonated so far."

"That's good." Yu Gongming nodded lightly, and Conan and Meng Yu also breathed a sigh of relief.

"Now, according to the instructions of Manager Matsumoto, a large number of police officers from the First Search Section have rushed to the ring line. Brother Hanomiya, do you have any clues about the location of the bomb?"

After Yu Gongming and the three of them looked at each other, Yu Gongming still spoke:

"We just discussed it and already have some ideas."

"Oh? Really? Tell me!" Officer Megure heard this and looked at Hanemiya Akira with hope.

"First of all, the prisoner said before that [the hint was given just now], that is to say, the hint was hidden in what the prisoner said before."

"According to our analysis, the so-called prompt is likely to be the conditions for the bomb to detonate!"

"Oh? Detonation conditions?" Officer Megure was confused.

"Yes, based on this idea, I analyzed these two conditions again and felt something was wrong."

"If the bomb cannot be found before the sun sets, the bomb will detonate. This condition does not provide many clues. After all, the bomb is most likely to be detonated on time, or it may be detonated manually by the prisoner."

"But if the train's speed is less than 60 kilometers per hour, the bomb will detonate, which is very intriguing."

"If the bomb is installed on the train, how can the prisoner determine the specific speed of the train? Is the bomb connected to the dashboard of the cab?"

"However, as far as I know, when the circular line starts running every day, for the sake of driving safety, all carriages, especially the cabs, will undergo comprehensive inspections."

"If the bomb had been installed at that time, it would have been discovered."

"However, if the bomb had not been planted in the early morning when the train was out of service, the cab would have been occupied after the train was running, and the prisoner would have had no chance to connect the bomb to the dashboard."

"So, the prisoner must have some way to correlate the speed of the train with the detonation of the bomb."

"So, what is this connection point?" Officer Megure asked.

"It's light!" Conan shouted.

"Light?"

"That's right!" Conan laughed:

"Officer Megure, think about it, doesn't it get dark after the sun sets? Moreover, when the train is moving, there is a place that will be temporarily blocked, thus losing most of the light source!"

"Wait...Conan, you mean..." Officer Megure's eyes widened.

"That's right, that place is the area in the middle of the railway tracks!" Conan said with a confident smile:

"I think the prisoner installed a light-sensing device on the bomb and connected it to the timer. Once the train passes over the bomb, the light-sensing device will trigger the timer because the bomb is not exposed to sunlight. Once the train passes over the bomb, the light-sensing device will trigger the timer. If the train is too slow and the bomb is out of the sun for a certain period of time, the bomb will explode!"

"Once the train reaches a speed of sixty kilometers per hour, the bomb will be able to illuminate the sun again within the specified time, and the light-sensing device will reset the timer!"

"That's why bombs still go off after the sun goes down!"

When Conan said this, he suddenly turned to look at Yu Gongming, and said with a smile: "Brother Ha Gong, how are you? I understand your reasoning very well, right?" He also made a look like asking for praise. expression.

"This kid is getting more and more skilled..." Yu Gongming smiled secretly in his heart and nodded seriously:

"As Conan said, according to the prisoner's tip, the bomb should have been installed between the railroad tracks!"
