"From 4 p.m. today, bombs will explode when the speed of the train on it is less than 60 km/h. In addition, bombs can explode if they are not defused before sunset. I'll just give you one hint: I put those five bombs in the 'X of XX' of the Eastern Capital Loop, where each X represents a word. Then come on, Maori Detective! The voice said sarcastically.

He ...... He's joking, right? Maori Kogoro said secretly wiping his sweat.

"No, he's serious!" Officer Twilight said solemnly, "Anyway, I'm going to have to get in touch with the headquarters right away." ”

XX of X? Asa Yu thought silently, what is that? Can blow up trains...... Under the seat? No, in this case, the bomb is relatively stationary with the train, and you can't feel it no matter how fast you drive. Where you can test the speed of a train......

"What's your opinion?" Conan asked Asa Yu quietly.

"I'm thinking about that 'X of XX'." Asa Yu was silent for a moment and replied softly. "Since the speed of the train can be tested, it shows that the bomb has something to do with the speed of the train itself, and this design is indeed possible. But if you just put it somewhere......" he thought silently again.

"I'm more concerned about the purpose of the prisoner's doing." Conan pondered for a moment and spoke, "Is it really the case of Mayor Okamoto of Seitama City?" ”

"How do I know?" Asa Yu rolled her eyes, "I wasn't there then, I went...... Hokkaido. With that, Asa Yu fell silent.

"yes!" Conan was also silent, "That was shortly after the start of his sophomore year of high school...... That thing. ”

"Oops!" Asa Yu suddenly sat up and shouted.

"What's wrong?" Everyone was taken aback and collectively looked at Asakura.

"They...... The three of them went home, and the train they took should be the Dongdu Ring Line! Asa Yu looked at Conan and anxiously pointed to the detective team badge on Conan's chest.

Conan's heartbeat seemed to miss a beat in an instant.

Dongdu Railway Comprehensive Headquarters

"What? A bomb was loaded on the ring line? The director of the Ministry of Railways was shocked, "The train must not be stopped!" Let all trains on the loop line move at 60 km/h, no, 70 km/h at once!! In short, there must not be a stop until they find the bomb!! ”

With the emergency order given, all the trains on the loop began to go crazy at life-and-death speeds.

On the loop.

"Hey, don't you think this car is weird?" Yuantai, who was looking out the window, said in wonder.

"What's weird?" Ayumi asked.

"It's almost at the rice flower station," Yuan Taiyi pointed out of the car, "but this car is driving faster and faster." ”

"Hey, hey! Motota, Ayumi, Mitsuhiko, can you hear me? At this moment, the detective armbands of the three suddenly rang.

"Is it Conan?" Hearing Conan's voice, Ayumi said happily,

"You guys, are you on the loop now?" Conan's voice was full of urgency.

"yes," Ayumi looked out the window, "what's the matter?" ”

"Hurry up..... Woo! ”

"Hey? Conan, what's wrong? Ayumi said strangely.

“...... It's nothing. A cold voice appeared, "I'll get out of the car later, let's go home quickly!" Then there was no sound.

“...... Oh. Ayumi said with a little disappointment.

The other side.

"What are you doing?" Conan glared at the shallow feather covering his mouth.

"They're already on the loop, and they're not going to do anything." Asa Yu looked at Officer Twilight, "Telling the three children about this will not only not help, but will further spread the fear." Right, Officer Twilight? He said in a sweet voice. Officer Twilight nodded approvingly.

"Anyway, what must be done now is to find the location of the bomb." In the last sentence, Asaba looked at Conan and said.

"I see!" Mori Kogoro suddenly exclaimed, "The 'X of XX' that the prisoner said meant 'under the seat' or 'above the shelf.'" ”

Wrong. Asaka frowned, how could it be possible to measure the speed of the car if it was placed in that kind of place?

"So, it's possible to be 'under the body'?" Officer Twilight said, looking at Kogoro.

"Uh......" Kogoro was momentarily speechless.

Officer Twilight's phone rang, and he hurriedly took Mori Kogoro away, leaving only Conan and Dr. Asaba.

The Doctor entered the room with a television in his arms, Asa Ha unconsciously stroking Watson's fur while Conan watched the loop-shaped train that sped by from time to time.

"With the ability of the police, half an hour of blockade is already the limit, right?" Conan looked at the hustle and bustle on the TV and spoke silently.

"Sunset ......"

"What?"

"Sunset." Asa Yu repeated. "The bomb would have exploded if it hadn't been defused before sunset."

"Why does sunset have anything to do with explosions?" Conan muttered to himself, "Does it have something to do with the lights?" ”

"By the way, I think I broke your skateboard." After being silent for a long time, Asa Yu spoke.

"If it's broken, it's broken." Conan said nonchalantly, "Just let the Doctor make another one....... Wait! ”

"The Sun!" Asa slapped his thigh, but slapped Watson's tail right in the face, causing him to let out a cry of dissatisfaction.

Asa Yu didn't care about this, "Doctor, is Conan's skateboard solar-powered?" ”

"Ah, that's right." The doctor nodded, looking at the excited two suspiciously, "What's wrong!" ”

"Huh!" Conan's glasses flashed a bright light, "It's the opposite of the working conditions of a solar skateboard!" It seems ......"

"It can be related to the train, and it can also be a place to avoid the sun......" Asaba also smiled.

"That's it!"

"Please take your time." The waitress elegantly placed the drink in her hand on the table, where two young girls were sitting. One is wearing a blue-green suit with tea hair, and the other is wearing a red jacket with a pale pink skirt, which looks beautiful and lovely.

"Xiaolan, red is really suitable for you!" The tea-haired girl teases her female companion.

"The garden is really ......," Xiaolan's face was slightly red, "because I and Shinichi are both lucky colors red this month!" ”

The girl is none other than Sonoko Suzuki and Moriran.

"Hey, anyway, I haven't seen Shinichi in a long time!" Yuanzi deliberately teased Xiaolan and said, "Shall I go with you?" ”

"Uh...... No need! Xiaolan's face suddenly turned red, waved her hand and said, "The movie is very boring!" He's the same ......"

"Just kidding! Who wants to be your light bulb! The garden squeezed his eyes strangely, "You are really naïve, it's so fun to play tricks on you!" But then again, your dad actually agreed to let you go to the midnight show? ”

"I don't care about him!" Xiaolan smiled and said, "He should be discussing with Conan what to eat at night right now, right?" ”

Railway Command.

"So, no suspicious items found?" Mori Kogoro asked.

"No, we've already looked for them all." The director shook his head and said solemnly, "And, please hurry up and find the bomb, the passengers in the car are about to riot!" ”

"Still can't find the bomb? Maori dude! Officer Twilight yelled anxiously.

"......" Kogoro Mori had a constipated expression on his face.

"Bell bell bell bell ring!!"

Officer Twilight's cell phone rang suddenly, and he didn't care about looking at the caller ID, so he hurriedly turned on the phone, and a young and magnetic voice came out of the earpiece.

"Officer Twilight, I'm Shinichi Kudo......"
