After the crowds near the possible routes of bombs and explosion-proof canisters had been evacuated, the people in the explosive ordnance disposal squad began to deal with this genuine B52.

"Now I'm worried about another problem." Qianyu leaned on the guardrail on the roof of the building, watching the explosive ordnance disposal team quickly pull the B52 copper ball containing the bomb out of the hospital, and put it into the big copper ball in the car.

, said.

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

"So, how will he tell us the clues?" Qianyu nodded slightly distressed.

"1o." Conan looked at his watch and said.

"?" Qianyu was confused.

"9,8,7,6..." Conan continued to count down.

"Bomb..." Qianyu glanced at the approximate time on his watch and understood what Conan was counting down. He turned his attention to the car with the bomb and started counting down with Conan "5, 4, 3, 2, 1.

"

"Bang!" A muffled sound came from the car, but the car was obviously intact.

"It seems like this big explosion-proof copper ball is quite effective!" Qianyu looked at the riot-proof vehicle with a smile.

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

"What's wrong?" Qianyu asked as he followed Conan downstairs.

"You still remember when the bomb was dropped, the prisoner used a toy helicopter to deliver the small bag to us, right?"

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

"There was that kind of airplane in the room just now!" Conan went down to the third floor and rushed towards 31o. "There is also a small plastic bucket hanging below!"

"Huh?" Qianyu was surprised and rushed into Ward 31o with Conan.

Sure enough, far away from the pile of airplanes directly above the hospital bed, a helicopter with a small plastic bucket was suspended in the center of the ceiling. The rope was very short, and the airplane was almost touching the ceiling, so I was focused on

Qianyu, who was on the B52, naturally didn't notice the helicopter.

"Sure enough, there is something." Conan found a chair and pulled the helicopter down from the ceiling. There was indeed a note in the plastic bucket under the helicopter. "It is also an explosion warning..."

"There are actually..." Qianyu gritted his teeth. "How many octagonal explosives did this guy steal?!"

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

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

"My surname is Shiratori, Shiratori Rensaburo." The man introduced himself. "I am a police officer from the First Investigation Division. Did you find anything?"

"Police officer ID card?" Qianyu asked.

"You little brat," Shiratiao smiled and showed him his police officer ID. "Can you tell me now?"

"I placed five bombs on the Shinkansen. These bombs will count down for five minutes after you see this note. After the countdown reaches zero, the bombs will be activated. As long as the train's speed is lower than 60 kilometers per hour,

The bombs will be triggered at any time. Of course, if the sun sets, these bombs will also be triggered. Whether you can save the Shinkansen trains depends on your ability."

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

After saying that, Officer Shiratori ran out the door, obviously preparing to make a phone call.

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

"Five minutes," Conan looked at the remains of the rope hanging from the helicopter. "How did he do it?"

"Same question," Qianyu tried to check the part of the thin wire stump that the helicopter was originally connected to the ceiling and the connection between the thin wire stump and the helicopter, and then checked the part of the helicopter where the bucket was hung, and confirmed

There is no mechanism that can sense weight. "I can't imagine how he did it? Wait... If there is no such mechanism, then..."

Qianyu looked around at the walls, looking for any pinhole cameras, because if there were no pinhole cameras, it would be impossible for the murderer to accurately calculate the time and start the five-minute countdown.

"They should be able to do it in time," Officer Shiratori came back. "If they are really qualified."

"Qualified?" Qianyu raised his eyebrows.

"The time I just reported to the Metropolitan Police Department was less than 6o seconds." Shiratori replied. "According to regulations, the Metropolitan Police Department needs to notify the relevant departments within 6o seconds after receiving the report. And the regulations of the railway department clearly show that

, after receiving the warning from the Metropolitan Police Department, it needs to respond within 6o seconds, and the train needs to make effective adjustments to the command within 6o seconds."

"..." Conan pondered slightly. "Excuse me, do the police have to start reporting to the Metropolitan Police 60 seconds after discovering an unexpected situation?"

"Yes," Officer Shiratori nodded. "How do you know?"

"That's what five minutes is all about," Conan shrugged. "Prisoners know these regulations very well."

"Ugh?" Qianyu's nose twitched, and then he suddenly looked at the note attentively. "The note smells so good..."

"Smells good?" Conan frowned. "Let me see?"

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

"Ah?" Shiratiao was stunned. "Oh, okay."

"This should be invisible ink," Conan held a lighter and burned the note. "We should be able to see..."

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

"As a reward for your wit and acumen, let me give you a hint: the bomb is placed on x of xx. Each x represents a Chinese character, so come and challenge me!"

"Back to the previous topic..." Conan immediately realized that xx of

Where did you find out?"

"Hmm -" Shiratori thought for a while. "The Metropolitan Police Department's series of reports are clearly stipulated in the Police Regulations of the Metropolitan Police Department; in the case of the railway department and trains, it is the railway center and the train driver, and the train conductor needs to know."

"What if the total time is five minutes?" Qianyu frowned and asked again. "Those who need to respond to the five minutes."

"Mayor?" Shiratori thought for a while and said hesitantly. "Generally speaking, the mayor will also serve as the director-general of the emergency command department, but higher-level officials may also hold this position."

"Wait a minute, I remember that the last mayor of Nishitama City seemed to be-" Conan fell into deep thought.

"Anyway, let the police defuse the bomb first. It's better to defuse it sooner rather than later." Qianyu shrugged.

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

"Didn't he mention the Shinkansen?" Qianyu was confused. "Let them search along the railway!"

"It should be a train on the Shinkansen line -" Conan said mid-sentence, and suddenly realized. "Wait a minute...it seems that he didn't specifically say that the bomb was on the train..."
