I am in Mihua, and the ladies all like me

On the other side, Serabelle and others began to tour the castle under the guidance of Natsumi Kosaka.

From the hall to the armory, to the dining room, kitchen and bathhouse, then to the study and bedroom.

The castle covers a large area and has a very spacious interior.

In particular, the layout and decoration inside perfectly restored the original German castle of the last century. Even people like Suzuki Tomoko, who are used to living in luxurious mansions, couldn't help but marvel at it.

But even so, after Serabelle and the others had been wandering around the castle for nearly half an hour, they still didn't see any trace of the Egg of Memory.

Just like this, another half hour passed.

When they came out of the last room on the second floor called "The Emperor's Room", everyone's face had a more or less dejected look.

They have been here for more than an hour and still found nothing.

Maori Kogoro muttered quietly: "I haven't found it after searching for so long. Could it be that the other egg of memory is also lost..."

As soon as these words came out, Gan Jiangyi and Secretary Mao Xiong couldn't help but look at him.

To be honest, although it sounds a bit discouraging and annoying, one has to admit that they have indeed spent quite a bit of time here, searching almost every corner of every room, and they were just short of digging deep into the ground.

Under normal circumstances, it can be concluded that the other egg of memory is not in the castle.

But if we give up like this, everyone would feel unwilling.

Just when everyone was hesitating and deadlocked, Serabelle applied to leave the team.

"If you guys still want to continue searching, I'm going to wander around the castle alone. Don't worry, I won't touch anything I shouldn't touch."

"Ok, no problem."

Kasaka Natsumi was very trusting and agreed immediately.

After obtaining permission to act alone, Serabelle reached the easternmost room on the second floor of the castle.

Looking down through the window, there were lush forests all over the mountains under the sky with a hint of dusk. Occasionally, the sound of birds singing could be heard, and the next second, a few birds were seen flying quickly over the top of the castle, like a few feather arrows that quickly disappeared into the distant mountains and forests.

Not seeing Pu Siqinglan, Serabell withdrew her gaze.

After spending ten minutes touring the rooms on the south and north sides in the same way, he finally came to the room on the westernmost side of the castle.

Through the window of the west room, you can clearly see a specially built staircase path leading down to an independent high tower on the right side of the castle's main entrance.

Serabelle didn't know much about architecture, so he didn't know why such a tall tower was built next to the castle, but he just built it that way.

However, what attracted his attention was not the tall tower, but a familiar figure below the tower.

That's Dr. Agasa. I didn't expect they haven't left yet.

From his perspective, Dr. Agasa was constantly looking into the tower door, not knowing what he was looking for. Then he suddenly turned around and ran up the stairs in a panic, looking quite anxious.

Serabelle narrowed her eyes slightly.

Is...something happened?

After a little thought, Serabelle turned and left the room.

When he reunited with Conan and the others, they were already on the first floor. Somehow they wandered back to the study of Kiichi Kosaka, the builder of this castle.

In fact, I have been to this room once before, and as expected, I found nothing, not even a clue about the Egg of Memory. Logically speaking, there is no value in searching it again.

But the facts prove that not only does it exist, but it is very abundant.

After all, they did find something.

When Serabelle walked into the room, the atmosphere in the study was a little weird.

Gan Jiangyi was sitting alone on the side. The backpack he was carrying when he came in was lost somewhere, and he only had a flashlight in his hand. "Inspector Shiratori" was watching over him on the side.

It feels like... watching a prisoner?

As for Conan and the others, they were lying on the ground next to the desk, surrounding a piece of floor that was lifted up like a cover.

There is a button board under the floor, and each button is engraved with a Russian word, which feels like a dial used to enter a password.

"What do you mean, have you found the entrance?" Serabell walked over and asked.

"Well, I guess so..." Conan said without looking back, "But it's just that I found it. The entrance should be right below, but no one knows the password. I tried several times but failed."

"I've tried both 'Memories' and 'Kisaka Kiichi', but neither of them worked." Kogoro Mori groaned, crossing his arms.

"Ah~ This is easy, let me do it."

Serabelle picked up a utility knife from the desk, pushed aside the people surrounding the button panel, and squatted down.

Just when Kogoro Mori and others thought that this guy had some clever tricks, he decisively did something that almost made everyone's eyes pop out.

Serabelle used her backhand to shave the tip of the utility knife into the gap of the button panel, and pried the entire button panel out with a light pry. She accurately found the two wires used to start the mechanism from the not-so-complicated small bundle of wires underneath, removed them from the button panel, and then put them together.

Boom——

It was like an ancient mechanism that was started again after being covered in dust for many years. There was a dull sound coming from below, and the floor in the study slowly opened to both sides automatically like magic, revealing a staircase leading downwards.

The mission was accomplished, Serabel stood up and clapped his hands, then looked back at the stunned people in the room and shrugged.

“See, it’s very simple.”

Chapter 144: The Youth Suicide Group

Time goes back to a moment ago, to the open space outside the castle.

After watching Serabelle and the others enter the castle and the gate close, Haibara Ai turned to the three little ones who were still looking at each other and breathed a sigh of relief.

"Okay, they've already gone in, so it's about time for us to go back~"

Hearing this, Dr. Agasa also got into the car.

But before she turned around, the girl's hesitant voice came over.

"Haihara-san..."

"Ok?"

Haibara Ai stopped and looked over, and saw the only girl among the three little ones, Ayumi Yoshida, standing there with her feet rooted to the spot, her watery eyes staring into the distance, and her little fists clenched tightly.

The fat boy Kojima Genta and the freckled boy Tsuburaya Mitsuhiko behind him also looked indignant.

Oh no, that's not quite right.

Because rather than being indignant, it would be more accurate to say that he exudes an aura of wanting to make big news from the inside out.

Haibara Ai blinked and immediately understood their intention.

"Wait, you three..."

Before she could finish her words, Mitsuhiko interrupted her.

"Don't you feel unwilling, Haibara-san?"

Huh?

Haibara Ai was stunned by this question, and thought to herself, why should she be unwilling?

Then Yuantai continued: "We can't keep dawdling here. Conan has left us to go treasure hunting. We must act immediately and find the treasure before him. Let Conan understand how powerful our Junior Detective Team is!"

"That's right!"

"That's it!"

Mitsuhiko and Ayumi also joined in.

Huiyuan Ai's expression changed slightly: "You three listen to me, this time it absolutely won't work..."

However, not a single word of her words reached them. The three little ones, who had already made up their minds, seemed to have agreed on something among themselves. After a cheer, they ran straight towards the direction of the tall tower they had noticed earlier.

"Wait a moment..."

Realizing that shouting was useless, Haibara Ai turned her head and looked at Professor Agasa who was looking out of the car with the window rolled down.

"I'll go call them back!"

After saying that, she trotted after him, leaving Dr. Agasa sitting alone in the car, holding out his hand through the window.

"Hey, Ai, slow down a bit and watch your step..."

"understood."

By the time Haibara Ai hurried down the stairs, the three little ones had already reached the entrance of the tower and put their hands on the door.

The seemingly heavy wooden door was actually not difficult to open at all. It opened with just a light push and moved inward with the sound of the door hinges squeaking.

When I walked in, I found it was surprisingly clean inside. There was nothing on the stone floor except a few bundles of hay.

Looking upward, there are several vertical ladders connected to several circles of platforms leading directly to the top floor of the tower. Since the platforms are circular, the entire interior of the tower can be basically seen at a glance as long as you look up from the bottom.

"What? It turns out there's nothing."

Yuantai complained with a pout when he didn't see the treasure chest he expected.

"No one said there must be something in here."

As soon as he finished speaking, Huibara Ai walked in from the back door, looked around and said.

Mitsuhiko and Ayumi were also a little discouraged: "What a shame, we were hoping to find a secret passage to the castle..."

"You...you guys...it's about time to go back..."

Intermittent voices came from outside the tower door. The children turned their heads and looked back. It turned out to be Professor Agasa.

The distance from the top to the bottom of the tower was actually not long, but maybe it was because he ran too fast, or because he was poisoned by years of fried chicken and cola, coupled with a severe lack of exercise, which weighed down his obese body, but just this short distance almost broke Dr. Agasa's old waist.

By the time I finally reached the door at the bottom of the tower, I could only lean against the wall and gasp for breath.

click -

It was like the sound of a mechanism loosening. The next moment when Dr. Agasa pressed his palm against the stone wall beside the door, the stone where his hand was pressed was suddenly pushed inward, swallowing half of his arm.

“Ugh!”

Dr. Agasa was startled and screamed subconsciously.

At the same time, the mechanism was activated, and a huge dark and bottomless hole suddenly opened on the ground at the bottom of the tower. Haibara Ai and the others were completely unprepared and felt nothing under their feet, and then fell into it.

"Something bad has happened!!!"

……

The time has come to the present, in Kiichi Kosaka's study on the first floor.

"The passage downwards...is open!"

Seeing the mechanism door slowly open, Gan Jiang's voice trembled with excitement, and his old eyes stared at the dark stairs going down, as if he had already seen the treasure right in front of him.

Serabelle casually threw the utility knife back onto the desk and smoothed down her clothes.

"Okay, you guys just go down from here."

Eh?

Conan was stunned for a moment when he heard this.

"Brother Sera, aren't you going down with us?"

"Well, I won't go with him. It seems that although Mr. Kiichi Kasaka likes to do tricks, he is basically puzzle-solving and has no lethality, so I won't accompany him."

Serabelle turned towards the door of the room and was about to leave when she stopped and spoke to the old butler.

"But just in case, Mr. Butler, please lock the door of this study after I leave."

"I understand." The old butler followed suit.

"Okay, see you all then."

Serabelle said and left the study.

After leaving the room, she heard the cumbersome sound of the door closing behind her. Serabell took out her cell phone, looked up the phone book and dialed Dr. Agasa's number.

The call was connected quickly, and the sound of Dr. Agasa driving came from the other end.

"Hello, this is Dr. Agasa..."

"it's me."
