Railway Headquarters.

"So, no suspicious items were found?" Mouri Kogoro asked.

"No, we have searched them all." The director shook his head and said solemnly, "And please find the bomb quickly, the passengers in the car are about to riot!"

"Still can't find the bomb? Brother Maori!" Officer Megure yelled anxiously.

"..." Mouri Kogoro looked constipated.

"Ring ring ring ring ring!!"

Officer Megu's cell phone suddenly rang. He ignored the caller ID and hurriedly opened the phone, and a young and magnetic voice came from the receiver.

"Officer Megure, I am Kudo Shinichi..." "Shinichi?!" Officer Megure was ecstatic, "Great, I have been waiting for you for a long time!"

"I'm sorry, Officer Megure." Shinichi's voice was full of apology, "I haven't been in Tokyo to handle cases recently, so I can't come back. I'm just coming back here temporarily. However," Shinichi's confident voice appeared again, "

I listened to everything Dr. Ali said!"

"The real location of the bomb is not under the seat, nor on the shelf, nor under the car body. The correct location should be-"

"Between the tracks!"

"Rail, between the rails?" Officer Megure was shocked.

"Those bombs will explode as long as they are not exposed to sunlight for a period of time." Conan said calmly on the other end of the phone. "If a train on the circular line passes over the bomb, the light will be blocked for a few seconds. Section 1

If the carriage is calculated as 20 meters, ten carriages are 200 meters. At a speed of 60 kilometers per hour, the speed per second is equivalent to 16.7 meters, which means that it takes about 12 seconds for the train to travel 200 meters. The buffer time of the bomb should be the time when the train passes the second

100-meter incident. Because of this, let the train switch to other tracks immediately. As long as the train breaks away from the circular line, there will be no danger of stopping."

"I understand!" Officer Megure said seriously, "Change the track immediately!"

This is the phone.

Conan put down his tie and wiped his sweat, "This finally solves the train crisis."

Qianyu raised his head: "But the murderer is still not found."

"That's right!" Conan sighed and leaned down.

"Speaking of which, Conan." Qian Yu suddenly spoke.

"Huh?"

"Have you noticed that the houses that have been serially set on fire in the past few days were all built by Moritani Teiji!"

"What!" Conan sat up suddenly.

Soon after, Officer Mumu and others returned to the ward.

"All five bombs have been recovered!" Officer Megure said to everyone, "Thanks to Kudo! However," he put away his smile, "the charge of these bombs is only a quarter of what was stolen from the Toyo powder depot.

Ah!"

"So, three-quarters of the gunpowder is still in the hands of the prisoner!" Mouri Kogoro touched his chin.

"The investigation is over." At this time, Officer Baitiao opened the door and came in.

"After investigation, Mayor Okamoto's son Kohei went to Izu early this morning." Officer Shiratori reported seriously.

"So, he must not be a suspect." Officer Megure said thoughtfully.

Conan and Qianyu looked at each other.

"By the way, Mr. Police Officer." Conan looked at Shiratori, "Where are the bombs on the ring line installed?"

"Four were installed near residential areas and one was installed on a bridge."

"On the bridge?" Qian Yu turned around and happened to see the news reporting this incident, with the bridge in the background.

"Huh?" Asaba pretended to be innocent and pointed, "I saw this bridge in Moritani Teiji's exhibition room!"

"Really!" Officer Megure looked at the bridge and said in surprise.

Conan smiled, very slyly, "Uncle, who designed those houses that were burned down in the serial arson incidents? If you investigate, you might find something interesting!"

......

Moritani House.

The doorbell rang, and Moritani Teiji opened the door, only to find two boys standing at the door. One was wearing a blue suit, with a red bow tie hanging on the collar of his shirt, and large black-framed glasses hanging on his handsome face, with confidence.

smile.

The other boy was wearing a black suit with a bandage on his head, but it did not affect his slightly cold temperament at all, and there was no fluctuation on his delicate face.

"Oh, it's you!" Teiji Moritani was stunned for a moment, then said with a smile. "Kids Conan and Asaba, please come in."

Conan smiled shyly and walked in. Qian Yu still looked expressionless.

"So, I would like to ask you two children, why are you here this time?" Moritani Teiji asked with a smile on his face.

"Uncle Maori asked us to ask him something!" Conan said with a smile.

......

"To put it this way, the coincidence is indeed a bit incredible." Moritani Teiji struck a match, lit the pipe, slowly blew out a smoke ring, and said.

"Then, for those who might have done this..." Conan asked seriously while holding a small notebook.

Qianyu stood up, walked to the cupboard, and stared at the photos placed there.

"That photo was taken when I was ten years old." Mr. Moritani saw Asaba looking at the photo, "Next to that are my parents."

Qianyu didn't say anything, just quietly looked at the boy in the photo smiling brightly.

"Professor Moritani, can we take a look at your exhibition room again?" Conan looked at Teiji Moritani with an innocent smile. "Officer Megure wants us to take some photos!"

"This...okay!" Moritani Teiji hesitated for a moment, but finally agreed.

Exhibition room.

"These are the works that were burned before I was 30 years old." Moritani Teiji said, "If you want to take pictures, please hurry up!"

"..." Qianyu didn't speak, just looked at the exhibition cabinet covered with black cloth quietly.

"Professor Moritani, what is this? I didn't seem to have seen this thing last time I came here!" Asaba pointed to the covered object and said lightly.

"..." Moritani Teiji frowned, instinctively feeling that something was wrong, but he couldn't say anything, so he had to suppress his doubts in his heart. He looked at Asa Yu's little back and said with a smile,

"Ah, this is just a small model I made when I was bored. It's nothing interesting."

Moritani Teiji, who was only staring at Asaha, didn't know that behind him, another small figure that he couldn't see had disappeared at some point.

"Oh? Small model?" Asaba did not turn around, still facing Teiji Moritani, which made him feel a hint of ominous premonition.

"If I'm not wrong, this should be your lifelong dream." Qian Yu suddenly pulled the black cloth and threw it aside. "It was also you who did not hesitate to steal the Japanese gunpowder warehouse and tried to use explosives and flames to destroy your old days.
