When the crowd had been evacuated from the route where the bombs and blast canisters might have passed, the explosives disposal team began to dispose of the real B52.

"Now I'm worried about another issue." Qian Yu leaned against the guardrail on the roof of the building, and said after watching the explosives disposal team quickly pull the copper ball of the B52 loaded with the bomb out of the hospital and load it into the car.

"This is not the end," Conan guessed Chiha's thoughts. "Isn't it?"

"So, how will he tell us the clues?" Qian Yu nodded slightly in annoyance.

“10。” Conan looked at his watch and said.

“？” Thousand Feathers was stunned.

“9，8，7，6。。。” Conan continued to count down.

"Bombs... Qian Yu glanced at the approximate time on his watch, understood what Conan was counting down, set his eyes on the car with the bomb, and began to count down with Conan "5,4,3,2,1." ”

"Bang!" There was a muffled noise in the car, but the car was clearly intact.

"It looks like this explosion-proof copper ball is quite effective!" Qian Yu looked at the riot car with a smile.

"Wait a minute," Conan suddenly remembered something. "Follow me!"

"What's wrong?" Following Conan downstairs, Chiba asked.

"Do you remember the bomb when the prisoner brought us that little bag in a toy helicopter?"

"What's wrong?" Chiba nodded, but still didn't understand what Conan meant.

"That kind of plane in that room just now, too!" Conan descended to the third floor and headed for 310. "There's a small plastic bucket hanging underneath!"

"Huh?" Surprised, Chiba rushed into Ward 310 with Conan.

Sure enough, a long way away from the pile of planes directly above the hospital bed, a helicopter with a small plastic bucket was suspended in the middle of the ceiling. The rope was very short, and the plane was almost attached to the ceiling, so Qianyu, who was focused on the B52, naturally did not notice the helicopter.

"Sure enough, there's something," Conan found a chair and dragged the helicopter off the ceiling, only to see a note in the plastic bucket beneath the helicopter. "It's also an explosion prompt...

"There's still ... Qianyu gritted his teeth. "How many octagonal explosives did this guy steal?!"

"Thirty-two kilograms and five hundred and eighty grams." The man's voice came from behind the two of them. "What are you two guys doing here?"

When the two of them followed the sound to the door behind them, they saw a tall and thin man looking at them.

"The surname is Shiratori, and Shiratori Ren Saburo." The man introduced himself. "I'm a police officer from the Search Section, did you find anything?"

"Police ID?" Qian Yu asked.

"You little ghost," Shiratori smiled, showing him his police ID card. "Can you tell me now?"

"I've put five bombs on the loop of the Eastern Capital, and these bombs will start counting down for five minutes after you see this note, and the bombs will activate after the countdown reaches zero. As long as the train is traveling at a speed of less than 60 kilometers per hour, the bomb can be set off at any time. Of course, if the sun sets, these bombs will also be triggered. Whether or not you can save the Shinkansen trains depends on whether you are able to do so. ”

“！！！” Officer Shiratori glanced at his watch and was shocked. "Damn it!"

With that, Officer Shiratori ran out of the door, apparently preparing to make a phone call.

"It doesn't look good... Qian Yu smacked his lips. "Is it still too late?"

"Five minutes," Conan said, looking at the remnants of the rope from which the helicopter was suspended. "How did he do it?"

"Same question," Qian Yu tried to check the part of the helicopter that was originally attached to the ceiling and the connection between the thin wire stump and the helicopter, and then checked the part of the helicopter where the barrel was hung, and confirmed that there was no mechanism that could sense the weight. "I can't imagine how the hell he did it? Wait a minute... If there is no such mechanism, then ... ”

Qian Yu looked around the walls, looking for any pinhole cameras, because without pinhole cameras, it would be impossible for the killer to calculate the time point and perform a five-minute countdown.

"It should be in time," Officer Shiratori walked back. "If they're really qualified."

"Qualified?" Thousand Feathers raised an eyebrow.

"I just reported to the Metropolitan Police Department for less than 60 seconds." Shiratori replied. "According to the regulations, the Metropolitan Police Department needs to notify the relevant departments within 60 seconds after receiving the report. However, the regulations of the railway department clearly state that after receiving a warning from the Metropolitan Police Department, it needs to respond within 60 seconds, and trains need to make effective adjustments to the order within 60 seconds. ”

“。。。” Conan pondered slightly. "Excuse me, do the police have to start reporting to the Metropolitan Police Department 60 seconds after they notice the accident?"

"That's right," Officer Shiratori nodded. "How do you know?"

"That's where five minutes came from," Conan shrugged. "The prisoners are well aware of these regulations."

"Huh?" Chiba's nose moved, and then suddenly looked intently at the note. "What a fragrant note..."

"How fragrant?" Conan frowned. "Shall I see?"

Conan sniffed the note, and then an interesting expression appeared on his face. "Officer Shiratori, lend me a lighter."

"Huh?" Shiratori was stunned. "Oh, okay."

"This is supposed to be invisible ink," Conan said, holding a lighter, scorching the note. "We should be able to see it...

A line of words appeared in front of the eyes of the three people.

"As a reward for your resourcefulness and acuity, here's a hint: the bomb was planted on XX X. Each X represents a kanji, so challenge me! ”

"Back to the previous topic... Conan immediately realized that XX X was almost a one-size-fits-all word, and immediately gave up judging by structure, instead returning to the previous result. "The prisoner knows these rules very well, Officer Shiratori, where did you know all this knowledge?"

"Hmm-" Shiratori thought for a moment. "The Metropolitan Police Department's series of reports are clearly stipulated in the Metropolitan Police Department's police regulations; The railway department and the train are what the railway center, the train driver, and the conductor need to know. ”

"What if it's five minutes?" Qian Yu frowned and asked again. "Those who need to react to a 5-minute duration."

"Mayor?" Shiratori thought for a moment and hesitated. "Normally, the mayor will also be the head of the Emergency Command, but higher-level officials can also be in this position."

"Wait a minute, I remember being mayor of Seishtama City like-" Conan was lost in thought.

"Anyway, let the police remove the bomb first, it's better to dismantle it early than late." Qianyu shrugged.

"Do you know where the bomb is?" Conan was surprised.

"Didn't he say everything about the Shinkansen?" Thousand Feathers was stunned. "Let them look for it along the railroad!"

"It should be a train on the Loop—" Conan reacted halfway through. "Wait... It seems that there really wasn't any special mention that the bomb was on the train... ”

"Let's look for it first," Qianyu said. "If you don't look for white, you don't look for it, do you?"
