"There is one thing that needs to be verified."

Uenkawa suddenly walked to the next room C, and Conan and Sera Makuru followed behind.

The owner of room c is a person with a large picture frame.

He had been asked and returned to his room.

Shangchuan Shun didn't look at the door lock first, and his eyes fell on the large picture frame that was packed. The width of the bag was as wide as a door, and it was placed separately on the sofa on the other side.

Conan had already touched the bag as a child.

He wanted to lift this up and weigh it, but the consequences were too heavy and he couldn't lift it at all.

"Uncle, what is this?"

"Don't move around, this one is very heavy."

Seeing that Conan was about to knock the painting down, he hurriedly held it, and said nervously:

"This is a painting entrusted by the client, but it is actually a fake."

"Why is it so heavy?"

Conan thought the heavy painting was a bit abnormal.

Just a painting, no matter how heavy it is, it is impossible to be so heavy that it can't be picked up, right?

"The frame is pure gold, so it will be very heavy." The man explained.

"Is that true..." Conan looked like he was ignorant, but in fact he was already suspicious.

...

The train slowly entered the tunnel.

There was no one walking around the carriage, and the aisle was in the darkness.

A footstep sounded in the quiet aisle. Although the aisle was covered with carpets, it still could not stop the trampling sound that was like stepping on people's hearts.

Hideichi Akai leaned against the corner wall and walked over step by step as he listened to the sound of footsteps.

He could not be sure if this person was gin or not, the only thing he knew was that this person was not Belmode.

But it's enough to know that this person is not Belmode.

He wore a knitted hat on his head, leaned against the wall, kicked his hands in his pocket, waiting for the man to recover.

Through the dim lights in the aisle, you can see the hideous scar on his face.

When we reached the corner, the person who came stopped.

The dim light shone down from the top, and the long silver hair was particularly conspicuous under the light.

Hideichi Akai looked up and asked naturally: "Have you found Shirley?"

"I don't know where that little mouse is hiding." He looked up slightly and showed a loud smile.

"She must be very scared now. After all, she has nowhere to escape on this train with a speed of 80 kilometers per hour."

Hideichi Akai observed his expression without any trace, trying to find out what was different, but this person's temperament, expression and expression were highly similar to Gin.

His understanding of gin is also stuck with some specific tags that the public knows, and there is nothing deeper and more private.

Therefore, there is really no way to distinguish it.

Thanks to Belmode's disguise as he was, otherwise he wouldn't have used such a dangerous method.

Hideichi Akai chuckled, "Then I hope you will find her as soon as possible."

The visitor glanced at him, said nothing more, and continued to walk towards the carriage ahead.

After Gin left, Hideichi Akai looked at the car window.

It was dim outside the car window, and he saw his face through the glass-shaped mirror.

He reached out to stroke the scar on his face, which was so hideous and uneven.

It is showing what happened.

...

In the No. 8 carriage, Shangchuan Shun, who had investigated the circle, had roughly determined who the prisoner was.

With some clues from Conan, the entire method of committing the crime was connected together.

He walked out of the No. B carriage at the crime scene and said to everyone in the corridor: "I already know how this secret room murder was completed."

"Ah? You already know?" Kogoro Mouri was a little surprised. He had no clues here, and he had just argued with these suspects.

Pingshika next to him also turned her gaze to Sumikawa, showing a surprised expression.

He knew this young man and had a good relationship with Bourbon, and Bourbon was a little unusual to him.

She investigated the other party's identity slightly. She was a high school student who had transferred from China for a short time. Bourbon used to be a chef at his house for a while before Poirot.

Sure enough, the one who can be favored by Bourbon will definitely not be an ordinary person.

She was a little looking forward to the teenager's reasoning.

Guaikawa Shun smiled, "Yes, the so-called secret room is just a man-made one."

The people in the No. 8 carriage had never heard of Kazukawa Shun's name, but since the other party said that the case was solved, it would be okay to listen to the other party's reasoning.

They are all reasoning enthusiasts. If the other party reasoned wrongly, they would not not mock him just because he was young.

Shangchuan walked to the door and showed everyone the security chain of the door of the No. B private room.

"I just checked it. There are five security chains in all the private rooms, and only six chains in Room B."

"The murderer should have secretly tampered with the door when the conductor was not paying attention." Shiliang Zhenchun, who had also sorted out the case, looked at the conductor.

All kinds of facilities on the train are equipped with supporting facilities, and it is impossible to set up a long one on purpose.

"Does this have anything to do with the length of the chain?" a person next to him asked.

"Of course it's relevant. When the chain is long, you can directly reach into the handle and buckle the safety button from the outside. In this way, the first person to find the body found that the private room was locked, and the so-called secret room was completed."

When someone heard what Kazukawa Shun said, someone immediately tried the door next to him, but the chain of the door was very short and his hands couldn't reach in at all.

"So, how did the murderer enter Room B? The conductor is in the aisle. He will definitely find someone entering Room B, right?"

"No, he can't find it." Uekawa Shin looked at Conan, and Conan released the sound he had just recorded.

Everyone heard a doorbell and subconsciously looked at the lights on the roof of the room, but none of them were on.

"At that time, the conductor heard the doorbell ring, but did not notice the lights, so he went to Room A because the lights in Room A were broken."

"Just when the conductor was having an argument with the guest in room A, the murderer asked the deceased to open the door of the box by phone. The aisle on the train was very narrow and the door was opened, so the conductor naturally couldn't see anyone entering Room B."

"Yes, I saw Mr. Murohashi open the door and talking on the phone." The conductor nodded, feeling that Ukawa Shun was right.

Huokawa continued: "After the murderer killed Mr. Murohashi, he used the remote control to make the watch put into the E-carriage in advance and led the conductor over, and then left and returned to his private room."

Ping Shijia interrupted at this time, "I remember the conductor said that when he was called to room e, he seemed to see a weird person. Is it the murderer who came out?"

"No, the train conductor saw me." Shiliang Masumu took out the picture frame from Room C.
