Daily life of a spy in the world of Conan

(Seeking follow-up reading and monthly tickets~)

Chapter 255 Why don’t you try this key?

The second floor of the castle.

Because Natsukawa and Conan left, Professor Agasa gathered the other children in a room.

"By the way, Uncle Natsukawa and Conan have been gone for almost an hour, and there's still no news? Should we go look for them? If anything happens, we can help."

Ayumi was a little worried about the two of them, mainly Conan.

"Are you sure you're here to help and not to cause trouble?" Huiyuan Ai threw the big and small ghosts on the bed and crossed her arms, "You lose again."

"I don't want to play anymore!" Aniya's head was covered with white tissue paper. They started playing poker after Natsukawa and Conan left. Now an hour has passed and she has lost all the money!

There was now so much tissue on her face that it almost blocked her entire vision.

Why?

Anya couldn't understand why she could lose even though she had the ability to read minds.

Haibara Ai is obviously an ordinary person, so how could she guess so accurately what cards she has in her hand?

"Then let's do our homework?" Huihara Ai silently picked up the schoolbag on the ground and pulled out a few small exercise books from it. "One for each of you to improve your grades, especially Ayumi. Your grades seem to have declined in the test on Friday.

Didn't you say that your mother almost dragged you to make up lessons today? Do some extracurricular exercises now while you have nothing to do, so that you can explain to your mother when you go back.

And Yuantai and Mitsuhiko, I don't need to say more about you, right?"

In fact, Haibara Ai didn't want them to do their homework, but these children would not be at peace if they didn't find something to do.

Didn’t you see that Yuantai and Mitsuhiko had already run to the door quietly?

The purpose of his action is too obvious.

"Where are you going?"

"Well, let's go to the bathroom and be back soon."

After saying that, Yuantai and Mitsuhiko ran away, their steps were so fast that it seemed as if there were monsters chasing them.

But it's almost the same. Behind it is a devil called the small study question set. If you are a step late, you may be stuck for several hours.

"I'll go as well."

Aniya glanced at Haibara Ai and found that she had no expression on her face. She pulled Ayumi and ran away, fearing that they would be caught and forced to do their homework if they were late.

"Dr. Agasa, don't you care?"

Haibara sighed and turned around, only to find that Professor Agasa had fallen into a deep sleep without her knowing.

“There is not a single reliable one.”

Haibara Ai walked out of the room helplessly. It seemed that these children would not be at peace unless they went out to explore.

A few minutes later.

The members of the Junior Detective League stood at the window of the room where the chess pieces could be seen.

They had no plans to go down to the basement to look for Natsukawa and Conan, but they wanted to help, to help solve the mystery of the chess pieces.

"We can't stay outside for too long, and we have to keep our voices down so as not to be discovered by the people or servants of the Mamiya family." Haibara Ai reminded in a low voice.

"I know" ×4

The four children were obviously very interested in solving puzzles. Even though it was already past midnight, they didn't seem sleepy at all.

"How annoying! I've only played shogi and don't know anything about chess." Mitsuhiko propped up his chin and spread his hands helplessly┓(??`)┏

It would be a bit troublesome without Conan.

All the previous cases were solved under Conan's leadership. Now that Mitsuhiko was thinking alone, he realized that he seemed to have not used his brain for a long time.

"Does Conan know the answer? Damn it, I should have asked him to tell us." Yuantai was eating a bag of potato chips in his hand. He came out mainly for adventure, and he said that he would leave the brainpower to solve the case to the others.

"Ania didn't notice it, but did Ayumi notice it?" Aniya asked, turning around.

Ayumi shook her head to indicate that the chess piece hit her blind spot.

"Actually, this is not difficult. I already know the answer. Do you want to know?" Huibara Ai asked.

Haibara Ai always felt that it was a bit dangerous for several people to lie on the window like this. Instead of wasting time here, it would be better to tell them the answer directly.

Before Conan went down, he had actually told Haibara Ai the answer, so she was an insider.

Moreover, this answer was something she had just thought of, a different answer from what Conan had previously speculated.

Before, she thought there was nothing wrong with Conan's reasoning and it should be correct, but just now when she passed by the hall, she accidentally discovered that "self-righteous intellectuals" might not necessarily refer to some relic of old man Mamiya in the basement.

Why can’t the answer to this riddle be the oil painting in the living room?

As a scientist, Haibara Ai also has a very high IQ. After thinking about the oil painting, she immediately remembered the meaning of the letter G in Kuroko.

"You know?" Anya's voice suddenly rose, a little surprised and doubtful, and then she began to use her skills, wanting to eavesdrop on the thoughts and say them out in advance, so that the other three little ones would admire her.

However, she tried for a long time but couldn't hear anything.

Haibara Ai's thoughts were too steady, and most of the time she couldn't hear them. This was one of the reasons why she had always been afraid of Haibara Ai. Of course, the main reason was that she always gave her endless homework.

"Of course we want to know!" the three little ones said in unison.

Just at this moment, they suddenly felt a slight vibration coming from under their feet, followed by a muffled sound and the sound of iron chains colliding.

Although the sound was very small, the castle was very quiet at night, so the sound was particularly obvious.

"It seems we have to hurry up. Uncle Natsukawa and Conan should have discovered something down there. This noise is likely to attract other people's attention. We need to make a quick decision! The people in the Mamiya family are a little strange, so be careful."

"Yeah!"×4

Haibara Ai:......

I feel like I'm talking to a cow.

The suicidal quartet, led by Haibara Ai, came to the hall.

The hall is a building within a building, with photos of the wife and her first husband hanging on the left and right. The staircase extends to the wall in front, then splits to the left and right, and an oil painting of the old man of the Mamiya family hangs in front of the staircase.

"Is this the place? Even if there is a secret behind such a large painting, we can't open it, right?"

Yuantai stepped forward and grabbed a corner of the old man's oil painting of the Mamiya family and pulled it out, but he could not move the painting at all.

"Lower left corner, hold the lower left corner of the painting and turn the knob to the right." Huibara Ai prompted.

In the chessboard arrangement, the angle of the letter G is -90°, so the way to open the channel should be to rotate it to the right to return the angle to zero.

Yuantai nodded in confusion, and Mitsuhiko grabbed the knob on the lower left corner and turned it to the right.

Sure enough, the oil painting was easily twisted to a certain angle.

Behind the oil painting is a rectangular depression with a steel ladder inside. The ladder extends upwards to an unknown length and is dark like a bottomless pit.

"There really is a passage!" Ayumi opened her mouth wide, her eyes full of stars. It turned out that Haibara was so smart.

Anya was a little unhappy because she heard the shock in the hearts of the three little ones.

My goodness, now that Conan is gone, it’s Haibara Ai who steals the limelight from her. It’s not fun at all!

Looking at the ladder in the wall, several people looked at each other with excitement. Even if Anya was unhappy, she wanted to know what this so-called treasure was.

Several children entered one after another, climbed the ladder, and soon reached the top.

Under the watch-shaped searchlight, the top space is clearly visible.

"We should be inside the conical roof of the castle." Huihara Ai looked around and instantly confirmed her position. This was the highest point of the blue castle.

"Where is the treasure?" Yuantai found that the entire space was empty. Not to mention treasure, there was not even a cockroach. It was too clean.

"What treasure? Could it be a scam?" Mitsuhiko was also confused. After a careful inspection, he found nothing.

"Is it here?" Aniya rubbed her chin. There was a square gap right in front of her. Light shone in from the gap and formed a rectangular projection on the ground.

She ran over quickly, wanting to be the first to try it.

"Hey, why can't it be opened?" Anya fumbled at the gap but couldn't find a way to open it.

"There seems to be a keyhole here." Huihara Ai fixed her eyes on the left edge of the square, where there was a long keyhole.

"strangeness......"

Haibara Ai shone a flashlight on the window, only to find that it was too clean. There was a fine layer of dust on the walls, but there was less dust on this window, and there was even a mark that looked like a handprint.

"It seems like someone came up here earlier!"

Haibara Ai suddenly felt a chill rising from the soles of her feet and pondered for a long time.

who is it?

Who came to this treasure trove in advance.

Conan? But Conan was with them all day.

Xia Chuan went fishing, so it shouldn’t be them.

As for now, it is even more impossible. There is only one passage in this space. Conan and Natsukawa should have gone to the basement and it is impossible for them to have been here.

The noise just now also proves that the two are still down there, so this definitely has nothing to do with them.

Therefore, this can only be someone from the Mamiya family!

"Oh no, it looks like this place has been discovered in advance. We should leave as soon as possible and wait for Xia..."

"Leave? Where?"

"Of course I will..." Huihara Ai's voice paused, her expression changed drastically. The person who spoke just now was... Mamiya Mitsuru! ?

She felt there was something fishy about that guy from the beginning, but didn't expect him to appear here?

Oh no, it must be the noise from Natsukawa and Conan that woke up Mamiya Man.

Haibara Ai turned around and saw that under the spotlight, Mamiya Mitsuru's smile seemed a little wanton and a little hideous.

"Thank you so much for helping me find my father-in-law's treasure. How do you think I should thank you?"

Mamiya Mitsuru's eyes narrowed with laughter, as if he had obtained a treasure.

He walked leisurely, seeming to enjoy the pleasure of getting the treasure. However, this pleasure was only for him personally, and every time he took a step closer, Huiyuan Ai and the others would take a step back.

"What's wrong with you? Don't you want to thank me?" asked Mitsuru Mamiya.

"Can you provide me with eel rice for a month?" Yuantai swallowed his saliva. The thought of the endless eel rice made his mouth water. Even though the other party didn't look like a good person, he still expressed his expectations.

"Hey! What are you still thinking about at this hour?"

Haibara Ai understood Conan's helplessness at times. These little brats, are they still naive enough to think that the man in front of them is a good person?

Why would a good person follow a bunch of little kids like that in the middle of the night?

"Eel rice? Sure!" Mamiya Mitsuru replied with a smile.

"Ah, what?" Huibara's eyes narrowed, and for a moment she didn't know whether she should step back or not. This... was a little different from what she thought.

Moreover, how did Mamiya Mitsuru's expression... gradually change from ferocious to kind? ! ?

"As for the other kids, feel free to tell us what you want. Once we sell the treasure, you can ask for whatever you want."

Mamiya Mitsuru had no ill will towards the children in front of him and was truly prepared to thank them.

He woke up when he heard the chains and the ground shaking. As soon as he noticed the noise, he went to the room where the secret passage was suspected to be in the afternoon, and then he happened to see several children walking out of the room.

Although he was curious why the adults didn't follow, he was more curious about what the children were doing.

Then, he saw Mitsuhiko and Genta working together to open his father-in-law's oil painting and discovered the passage behind the painting.

Wow, Mitsuru Mamiya exclaimed, his father-in-law is really a talent, he actually put the treasure behind his own oil painting. Just as his wife had said before, he is a self-righteous intellectual.

Then, he thought of what Xia Chuan asked him in front of the oil painting in the afternoon. Perhaps by then, the other party had already solved the puzzle?

No wonder Xia Chuan's expression seemed strange at the time, so this is what he meant.

As for why he didn't tell him, Mamiya Mitsuru felt that the other party probably wanted to let the children he brought experience the fun of treasure hunting.

The treasure was left by his father-in-law. Even if it was found by these children, it belonged to their Mamiya family. Why would he poison a few children just to hide the news?

As for Mamiya Shiro, Natsukawa had said before that the other party was the first-line heir to the inheritance. If he wanted to kill him, he would definitely kill him.

He had originally planned to take action against Mamiya Shiro in the near future to avoid getting nothing in the end, but he couldn't be too hasty and had to plan it carefully.

There is also Nobuhiro Mamiya, who is also his target, but not the first target, so she can be put aside for the time being.
