"Shinichi?!" Officer Twilight was ecstatic, "Great, I've been waiting for you for a long time!" ”

"I'm sorry, Officer Twilight." Shinichi's voice was slightly apologetic, "Charlotte hasn't been in Tokyo lately, so there's no way to rush back." I'm only coming back here temporarily. However," Shinichi's confident voice reappeared, "I've heard everything from Dr. Asasa!" ”

"The real location of the bomb is not under the seat, nor above the shelf, nor under the body. The right place should be—"

"Between the railroad tracks!"

"Between the rails and the rails?" Officer Twilight was taken aback.

"Those bombs explode as long as they don't shine in the sun for a while." On the other end of the phone, Conan said calmly, "If the train on the ring line passes above the bomb, the light will be blocked for a few seconds. If one car is calculated at 20 meters, ten cars 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. And the buffer time of the bomb should be the incident of the train passing 200 meters. Because of this, it is now possible to immediately turn the train to a different track, and as long as the train is off the loop, there is no danger of stopping. ”

"I see!" Officer Twilight said solemnly, "Change the track immediately!" ”

This end of the phone.

Conan put down his bow tie and wiped his sweat, "This is the solution to the train crisis." ”

Qian Yu raised his head and pushed his pair of gold-rimmed glasses: "However, the murderer is still not found." ”

"yes!" Conan sighed, leaned down, and lay down on the side of Asa Feather's bed, "By the way, what are you doing in a hurry?" ”

"That's right!" Asa Yu reacted suddenly, "I found something! He looked at Conan solemnly.

"What's the matter?" Conan looked at Asa Feather strangely.

"In the morning, I left the doctor's house and went to the villa of Teiji Moriya last time." Asa raised his head, "As a result, I found ......"

"The houses that have been set on fire in the past few days are all built by Emperor Moriya!"

"What!" Conan sat up sharply.

—————————————————————————————————————————————————————

"All five bombs have been recovered!" Officer Twilight said to the crowd, "Thanks to Kudo! But," he put away his smile, "these bombs only have a quarter of the charge stolen from the Toyo powder magazine!" ”

"So three-quarters of the gunpowder is still in the hands of the prisoners!" Kogoro Mori touched his chin.

"The investigation is complete." At this time, Officer Shiratori pushed the door and entered.

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

"In that case, he must not be a suspect." Officer Twilight said musefully.

Conan and Asa glanced at each other.

"That's right, Mr. Officer." Conan looked at Shiratori, "Where are the bombs on the ringline?" ”

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

"On the bridge?" Asa Yu turned around and saw a news report about the incident, and the bridge was in the background.

"Huh?" Asa Yu pretended to be innocent, "I've seen this bridge in the exhibition room of Emperor Moritani!" ”

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

Conan smiled, slyly, "Uncle, who designed the houses that were burned down in the series of arsons?" If you look into it, you might find something interesting! ”

......

Moriya House.

The doorbell rings, and Teiji Moriya opens the door, only to find two boys standing at the door. One was wearing a blue suit, a red bow tie hanging from the collar of his shirt, and large black-rimmed glasses hanging on that delicate face, with a confident smile. Another boy was dressed in a black suit, with a bandage on his head and a large tennis bag. However, it did not affect his cold temperament at all. There was no fluctuation on the delicate face, only the amber pupils shimmered with golden light.

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

Conan smiled shyly and walked in, Asa Yu still had a blank face.

"Then may I ask the two children, what are you here for this time?" Teiji Moriya asked with a smile on his face.

"It's Uncle Maori, please ask him something!" Conan said with a grin.

......

"So, it's a bit of an incredible coincidence." Teiji Moriya struck a match and lit his pipe. Slowly exhaled a smoke ring and spoke.

"Well, for the ...... who might do this," Conan asked, holding a small notebook with a serious face.

Asaka stood up and walked to the cupboard, staring at the pictures that were placed there.

"It was a picture I took when I was 10 years old." Mr. Moriya saw Asaba looking at the photo, "Next to that are my parents." ”

Asa Yu didn't speak, just quietly looked at the boy in the photo and smiled brightly.

"Professor Moritani, can we take another look at your exhibition room?" Conan looked at Teiji Moriya with an innocent smile. "Officer Twilight wants us to take some pictures!"

"This ...... All right! Teiji Moriya hesitated for a moment, but finally agreed.

Exhibition room.

"These are my works before I was thirty years old, which were burned." Teiji Moriya said, "If you want to take pictures, please hurry up!" ”

"......" Asa Yu didn't speak, just quietly looked at the display case covered by a black cloth.

"Professor Moriya, what is this? I didn't think I'd seen this thing last time I visited! Asa Yu pointed to the covered thing and said lightly.

"......" Teiji Moriya 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 the small back of Asa Yu, and said with a smile, "Ah, this, it's just a small model I made out of idle and boring, nothing to look at." Teiji Moriya, who was just staring at Asa Yu, didn't know that behind what he couldn't see, another small figure had disappeared without knowing when.

"Oh? Small models? Asa Yu didn't turn around, still with his back to Teiji Moritani, making him feel a hint of foreboding.

"If I'm not mistaken, this should be your lifelong dream," Asaba pulled the black cloth and threw it aside, "It's also the root of your old building that you didn't hesitate to steal from the Oriental powder magazine, trying to destroy your old building with explosives and flames, Seitama City, right?" ”

The boy turned around and quietly looked at Teiji Moriya, whose face had changed abruptly, his golden pupils as if reflecting a burning flame.
