"Huh?"

Mitsuhiko searched for clues on the other side of the room with a watch-type flashlight, but when the door opened here, it was an ordinary hallway, and there didn't seem to be anything suspicious.

It wasn't until he heard the sound of a small object falling to the ground that he turned his head to look into the middle of the hallway.

Something reflective seemed to fall there.

He cautiously walked in to take a look...... A pair of glasses...... It's Conan's glasses!

But...... Conan must have disappeared, why is he here......

Outside the window in front of him, facing the gate of the tower, he could faintly see that the tower door was slowly opened......

“………”

Mitsuhiko swallowed a mouthful of saliva and walked out as if he had made up his mind.........

…………

"Little Mourning...... Mitsuhiko seems to be gone......"

In the dark studio, Ayumi looked around uneasily, and Mitsuhiko seemed to have not moved for a long time, and she never saw Mitsuhiko again.........

"Could it be...... Something happened to him too? ”

Gray Yuan pulled Ayumi out of the studio quickly, and it happened to be the charred tower outside...... However, the gate of the tower was open at this time......

"The Gate...... Opened? ”

Ayumi said suspiciously, when they came over during the day, it was definitely locked, but now it is opened.........

"Not a squirrel bite ......"

Gray Yuan carefully checked the lock, she originally thought that the squirrel was too anxious to bite off the lock, but she didn't expect it to be not......

"It seems that Mitsuhiko has probably already gone in......"

Gray Yuan turned to look at Ayumi.

"I'll go in and find them now, if...... If you count to three hundred seconds and I don't come out, you can get out of this castle quickly, and maybe you can be saved if you get to the main road. ”

"Wait, I'm ...... too"

Ayumi also wanted to go, but was stopped by Ashbara.

"It's just the two of us now, what if we go in together and we both get caught."

"This ......"

"We have to make sure that someone can go out and call the police, so you wait here for three hundred seconds, understand?"

Ayumi was finally persuaded by Ashbara, so she nodded in agreement, and then watched Ashbara walk into the charred tower......

………

“………”

Gray Plains lowered his pace as much as he could, so that he could not make a sound, and quietly walked into the tower......

She clings to the wall and walks up the stairs...... A small room, what seemed to be a toilet, came into view, and with a wary glance, there seemed to be nothing, but she walked in anyway.

It looked like an ordinary toilet, but after seeing the castle's secret doors, she was reluctant to let go of any possibility.

Maybe there's some secret door in there, too.

"Is it here?"

Ash Yuan closed the toilet lid, then stood on it, tiptoeing the light on it...... There are only so many things that can be touched here, and the only thing that can be the secret door switch is this light.

The lamp was turned and a secret door behind the door was opened...... Sure enough, there is a secret door!

She quickly got in, and she didn't care if there was any danger, maybe Katayama Conan and they were inside.

It's pitch black inside, too...... Luckily, she still had a flashlight from the doctor, so she could see the way inside.

"Gray Plains!"

“！”

Gray Yuan looked up suddenly, and Ayumi's voice actually came from above.........

…………

"295,296,297,298,299,300, Gray Plains, count to three hundred seconds!"

Ayumi shouted inside, but there was no response, she looked around again, and there was no one around, a little scared.

She still didn't want to leave on her own...... Finally, he opened the door tremblingly and walked inside.

However, she didn't have the consciousness of Ashbara, and the ground creaked and rattled, which alarmed the people in the tower.........

Ayumi walked up the stairs slowly, not noticing that a secret door was opened at the bottom of the stairs, and a pair of eyes were staring at her in the dark.........

"Here... Is it a toilet? ”

Ayumi walked inside and subconsciously locked the door from the inside, because she was afraid, so that she would have some sense of security.

But unexpectedly, before she could react, there was a knock on the door.

"Gray Plains!"

Ayumi thought of Ashbara for the first time, after all, she saw Ashbara come in with her own eyes, and at this time, it was easier for someone to think that it was Ashbara.

But the next second she was stunned...... Definitely not the Gray Plains......

The door was slammed and the lock was almost deformed, was that criminal?!

Ayumi froze in place, almost about to cry, a little girl would inevitably be scared silly when she encountered this situation......

The moment the door was knocked open, Gray Hara burst out of the secret door, pulled Ayumi in, and closed the secret door again.

"Little ......"

Ayumi was pleasantly surprised, and was covered by Gray Plains.

The door was slammed open in an instant, and a man rushed in in a hurry, looking around......

As if noticing something, he walked to the front of the toilet and saw the light reversed......

He was already familiar with the structure of the tower, and immediately realized that the secret door had been opened......

Through the crack in the secret door, he could clearly see that someone was coming towards the secret door...... What to do...... Are you about to get caught?

"Squeak!"

The squirrel's cry was heard, followed by a loud commotion......... It seemed to bite off the handrail of the staircase and push it down.........

The footsteps faded away, and it seemed that the squirrel had led the man out.

"It's a squirrel...... I don't know how it knew we were here, but I'm glad to have it......"

Ash Yuan breathed a sigh of relief, at least they were safe for now.

As for the squirrel, she knew that even if it was a criminal, it would be impossible to catch the squirrel.

"Xiao Ai, it's really good that you're okay."

Ayumi said happily, at least there was nothing wrong with Gray Hara.........

"Shhhh

Gray Yuan's heart warmed...... The feeling of being cared for by someone, no one should hate it, but I still have to say it, after all, this thing is still too dangerous.

"Alright, let's move on!"

Ayumi also happily pulled Gray Yuan to continue walking, and Gray Yuan had planned to explore in this secret door, so he followed.

“…… This, this is ......"

Walked into the dark passage...... A dried corpse lay on the ground, already a skeleton, and it was impossible to see who it was.

"It's been a long time since I've been dead...... I'm afraid that this corpse is the person who carved the words in the secret passages of the castle. ”

"It should be that Mr. Katayama and Conan found the body, so they were knocked unconscious and taken away, and the body was transferred here........."

As he spoke, a bright light inserted between the two of them......

The old lady's face emerged from the darkness and looked kindly at Ayumi and Ashbara.

"You two little girls, why didn't you go to sleep?"

Her voice was gentle, but it sounded more like a demon's whisper to Ashbara......
