"Since I invited you to find the treasure, you have already heard about the treasure-related things from the owner of the castle, so I will not repeat it."

Gray Plains has a very good memory, the complicated road in the castle, she has only been here for an afternoon, and she is already familiar with it as if she is visiting her own home.

"If you come when it's darker, you should be able to see that there's a charred tower on the left-hand side of the door," she whispered in a controlled voice. ”

"Uh-oh." It's okay, I can see it when it's dark.

"It was the bedroom of the deceased Mamiya Lady, and according to the gardener here, she usually lived abroad. But four years ago, to celebrate the old woman's birthday, she returned home and temporarily stayed in the tower – arriving in the middle of the night and catching fire at dawn. ”

Speaking of this, Gray Yuan sighed softly

"Not only her, but also her friends and servants who accompanied her were buried in the fire cave, and the death toll was as high as fifteen, and all of them were burned to the point of not being human."

"It's miserable." , Anyway, why wasn't the gardener of this house fired, and it really didn't matter if he publicized the owner's negative news so much.

And that was just the beginning – two years after the tragedy, a new servant disappeared without warning.

"During the police investigation, a maid who had been close to him revealed that the missing person had said the night before he disappeared, 'There's something good in that tower.'"

"So they sent people to search the tower, but they didn't find anything. It wasn't until four days later that a skinny, bone-covered corpse with an empty stomach was found in the nearby forest—it was the missing servant. ”

"Alas......", I almost forgot, there is another one in the woods, I really don't want to go out in the rain, this errand is better left to the door panel.

Just as he was thinking about it, Gray Yuan Wai in front of him suddenly stopped. Bai Shu was stunned and stopped.

Looking up, there was the room he had just come to in front of him—the same place where Mamiya wanted to take him to a failed chess piece.

Shiraki walked into the house and knocked on the wall twice, "Is it missing in this room?" ”

"Yes. Originally, I, Yoshida, and Edogawa were in the next room, and here we were Kojima and Tsuburaya. When they were fighting, they almost fell out of the window, so Conan hurried over and said a few words to them. ”

Gray Yuan said as she walked over to the wall, her hands behind her back, and her toes tapped somewhere on the ground

"Not long afterward, Yoshida and I came over, and when we arrived, Conan was gone. The two boys were too busy playing to notice where he went, and by the wall—right here, there was a chair upside down, and a few thick books scattered around. ”

After speaking, she looked up at Bai Shu, "How is it, do you have any ideas?" ”

Shiraki walked over to where she stood, took two steps back, and pretended to think against the wall for two seconds.

The wall is covered with dark checkered wallpaper, the left and right sides are decorated with mosaic bookshelves and other objects, and in the middle hangs an old-fashioned clock with the time pointing to 3:20, which is very inconsistent with the actual time.

After walking through the process of thinking, Shiraki stepped forward under the gaze of Gray Yuan, opened the glass case of the clock's cover, and turned the hour and hand hands.

The two spun in circles, and when they finally coincided towards 12 o'clock, a series of small clicks were heard.

The hidden mechanism was touched, and a revolving door suddenly appeared on the originally flat wall.

Gray Yuan Wai stood close, almost swept by it, she was not too surprised, and stepped back a little, and the white tree raised his hand to stop the door halfway through.

Seeing this, Gray Yuan Wai walked back and looked at the thick darkness behind the door

"It's pretty much what I thought...... When I came in the afternoon, I always felt that the thickness of the walls between the two rooms was not quite right. ”

"Conan must have noticed the problem when he ran over, turned his watch casually, and was slapped in by the door without paying attention."

Shiraki knocked on the door, which seemed to be made of solid wood, making a slightly crisper sound unlike the wall

"The sound insulation effect is not very good, if he shouted and banged on the door at that time, it would completely attract the attention of outsiders.

"yes." , Gray Yuan Wai rolled his eyes that were not very obvious, "The reason why I didn't do that...... Maybe I was attracted by something in the door, and I probed deeply, but I found it difficult to get out of it. ”

Shiraki completely agrees with this point of view, as the protagonist of the detective world, Conan not only has a first-class mind, but also has the ability to die.

Unlike the old but well-maintained outside world, as soon as the door was opened, the smell of dirt and dust greeted you.

The secret passage was obviously not cleaned, and the white tree glanced around, and saw patches of moss and mold in the corner, and the road here was not wide, it was a step more than a meter wide and extending downward.

He withdrew his gaze and looked at his companions, "How about it, can you go in and have a look?" ”

"Hmm." At the same time, she also picked up the book and put it by the door, ready to jam the door, leaving a way for the two to leave.

"No, you don't." , Bai Shu put the book back again.

He walked into the secret passage and pointed to the top of the revolving door, "There is a handle here, just open it from here when you come back, the book is outside, but it is easy to be exposed." ”

Hearing this, Gray Yuan walked up to him, tiptoed to look up, and by the light coming in from outside, he could indeed see a small bulge.

She nodded in agreement, then flicked her wrist twice, and soon, a beam of light illuminated a small area around her watch.

- This multi-functional watch is of course also the creation of the doctor, and after the white tree closed the door, Gray Yuan Wai adjusted the watch to illuminate the feet of the two people, and they followed the steps one after the other, down to the bottom.

Below was a relatively open space, and Gray Plains raised his hand and took a cursory look around.

The light of the flashlight is not too strong, and you can only vaguely see the forks and steps in all directions, and the complex underground lair here looks like some kind of creature, and there is no Conan or the doctor in the field of vision.

She withdrew her gaze and light, trying to find a clue from the beginning.

However, as soon as he turned around, he saw Bai Shu standing a few meters away, looking down at the floor under his feet, as if he had noticed something.

"What's wrong?" , Gray Yuan shook the flashlight, and also shone on the soles of his feet.

It was supposed to be something that would be very conspicuous and enough to attract attention in the dark. But contrary to what she had imagined, the beam of light only illuminated the empty corner of the wall.

There is nothing there.

In her questioning gaze, Bai Shu squatted down and pointed to the ground, "Get closer, what can you see from so far away." ”

"Do detectives love to sell off so much? It would be nice to just tell me no. ”

He said this, but Gray Yuan Wai still approached and squatted next to him. l0ns3v3
