Just thinking about it, Haibara Ai felt the person next to her move.

She turned her head and saw Shiraishi sitting up and looking out the window, as if she was a little confused about where she was.

"We are on the Eastern Metropolis Ring Line." Haibara Ai briefly explained what happened before.

Shiraishi nodded, surveying the surrounding scenery as she spoke.

He quickly found an iconic building.

According to the information I just found at the police station, the Sumida Canal Bridge with many holes is probably nearby.

After the train went on for a while, Shiraishi finally saw a wide canal diagonally ahead.

I'm not entirely sure that the bomb is here, but let's try it first...

So, before Haibara Ai could finish talking about the situation, she saw Shiraishi fall back on the back of the chair.

She stopped, sighed, and put the pillow she was holding behind Shiraishi again. After sleeping for so long a day, do you really need to go to the hospital again...

Shiraishi turned on the mask, and after the 5-second blurring state ended, there was a black cat next to the rails.

It ran along the rails to the bridge and called the fox out.

After searching for seven or eight minutes together, a train galloped past.

Shiraishi ran to the railroad track and waited for it to pass, when it was suddenly patted on the side.

Shiraishi turned his head and looked at the fox who had slipped beside it at some point, wagging his tail proudly on his face, then looked at a gray dust paw print on his body, and raised his paw silently.

…

A minute later, the fox, who was pressed to the ground and rubbed twice, showed the cat the way to the bomb.

The noise of the train passing by was very loud. It actually blew twice just now, but Shiraishi didn't hear it, so it walked over and patted it friendly. I didn't expect...

huh.

Shiraishi looked around the bomb. This time the bomb was much more complicated than the one in the previous cat bag, but it still conformed to the basic principles of Kexue World Bomb.

Shiraishi originally wanted to demolish it, but after thinking about it, he stopped.

It pokes a private message to Hongye, then goes around the bridge and confirms the name of the bridge again. After that, Shiraishi lifted the call to the fox and returned to his main body.

A few minutes later, an anonymous call came from Shiraishi's mobile phone, which of course was from Hongye on demand.

The signal on the train is not good, but the train is just close to the city now, and it can barely be received.

Shiraishi picked up the phone, got up and walked to a place where there were few people, and kept the call records on his mobile phone, so that in case someone was curious about the source of his intelligence in the future, it would be easier to deal with it.

Shiraishi hung up the phone a minute later.

He was about to call the Mumu police department, but another call came in first, it was Conan's number.

Shiraishi pressed the answer, put the receiver close to his ear, and heard Conan lowered his voice and told him mysteriously that there was a bomb on the Dongdu ring line.

Then Conan added: "If the black cat is in a train with you and has a fox, you can try to find a bomb, although it is unlikely to be installed inside the train, but..."

"No. I heard about it just now, and I was just about to tell you this."

Shiraishi couldn't figure out where the vest gave the impression of "carrying a fox with you every day".

However, now that the location and type of the bombs have been determined, the task can be completed as soon as possible. After all, there are still a quarter of the tasks left behind.

"The bomb wasn't on the car, it was in the middle of the tracks on the Circle Line."

Shiraishi reviewed the plots he had seen before, plus the field research just now, and reminded:

"It might have a light sensor on it that casts a shadow as the train goes over the track, and if the train goes too slow and the shadow stays on for too long, the bomb will explode. There's no sunlight after the sun goes down, so it's also triggered."

"...So that's how it is!" Conan already felt that this speculation was very reliable.

After careful scrutiny, I feel that this is completely the truth.

The Dongdu circulation line is very long and has a wide span. If the prisoner uses a wireless remote control to detonate, it will be difficult for the signal to cover the entire route. Although other methods can be linked to the speed of the train, the condition of "the sun goes down" is not easy to achieve.

And if it's using light... it really makes sense.

Conan turned around quickly and was about to tell the police the news, but he suddenly found a circle of people around him who were eavesdropping on his phone calls.

Conan was startled and laughed dryly as he watched several police officers.

The act of answering the phone secretly doesn't seem to be as secretive as he thought...

In fact, there is no way to do this. After all, the bomber is obsessed with a pair with Kudo Shinichi, and Conan is the person who has the most frequent contact with Kudo Shinichi in the eyes of the police.

At this time, seeing Conan answering the phone, he suddenly showed a look of sudden realization, and the Mumu police department suddenly felt saved: "Is it from Brother Kudo? Does he know where the bomb is?"

"No, it's Brother Shiraishi... I'll turn on the speakerphone." Conan pressed the speakerphone button as he spoke, time was tight, so he didn't need to repeat it.

Shiraishi heard Conan's reminder to turn on the hands-free~lightnovelpub.net~ He paused slightly and continued:

"Also, I just received a call from Shinichi Kudo, who said that one of the bombs was on the Sumida Canal Bridge.

"You can confirm the situation first. If other bombs are of the same type, even if it is too late to find other bombs to prevent the explosion, the vehicle and passengers can be evacuated to a safe place in time."

Conan heard the pause in Shiraishi's words, and then heard him suddenly mention Kudo Shinichi, and immediately understood - the person who told Shiraishi the location of the bomb was definitely the black cat.

Shiraishi probably wanted to take the black cat out of the police's sight, but he himself was always sitting in the car, and his whereabouts were very easy to track. If he himself was the one who found the bomb, it would become suspicious, so he had to pull out a Kudo Shinichi who no one knew where he was.

Conan has no opinion on this. Before, he also pulled Shiraishi out to pretend to be a life mentor.

He just suddenly felt that Shiraishi's face was not thick enough, and he had to stop talking nonsense. His character was too good, and sometimes it would become a burden...

Fortunately, the Mumu police department didn't have too much contact with Shiraishi, so they didn't hear anything unnatural in that sentence.

The Megumi Police Department actually noticed Shiraishi's pause.

But he simply thought that Shiraishi drank too little water today and had a bad throat.

Moreover, compared to the amount of information in Shiraishi's words, all other factors immediately became unimportant.

The Mumu police department was overjoyed when such important news fell from the sky. He contacted the mobile team and asked them to confirm the situation of the bomb on the bridge as soon as possible.

If the situation is really as Shiraishi said, they can rest assured that the trains on the Circle Line will stop at the stations of other lines and put down the passengers first.
