In fact, the same is true for Haibara Ai, but Aniya doesn't dare to have any feelings for Haibara Ai for the time being.

Because in Bond's prophecy, as long as she has any bad thoughts about Haibara Ai, she will be the one who suffers in the end and has to work overtime to do homework.

"Behave yourself!" Natsukawa turned and looked at Haibara Ai.

Huiyuan Ai immediately understood and shrugged, saying, "Don't worry, I will take good care of her. If Aniya doesn't want to increase her homework, she should be very obedient. Don't you think so, Aniya?"

Anya didn't want to talk and pushed Bond out of the room.

Because of Tian Yan Shengnan's little episode, the few people were unable to enter the secret passage.

Conan led the Young Detective Team to wander around the castle and discovered several places that looked like secret passages. He planned to learn about these secret passages and secret doors in advance, and then go check them alone after dark when everyone went to bed.

The entire castle is full of secret passages. The distances between many rooms are problematic, and there are large gaps in the middle of the walls. These are definitely secret passages.

"Who was the master who died fifteen years ago? Why did he set up so many secret passages in his home?"

Walking around the castle, Conan found no less than ten places that might be the entrances to the secret passage, but he did not try to open them easily.

The enemy is in the dark while he is in the light, and there are a bunch of kids around him. If they rashly open the secret passage and Xia Chuan is not around, it would be easy to cause the whole team to be wiped out if the person blocking the door is waiting for them inside.

As for Xiachuan.

While these people were not paying attention, Xia Chuan opened the oil painting in the living room and came to where the treasure was hidden.

Chapter 252: Self-Righteous Intellectuals

Turn the old-fashioned F-type key to open the hidden window in front, and what comes into view is the beautiful scenery of the forest under the afterglow of the sunset.

The forest is lush green and full of vitality, and the green forest is set off by the orange sunset, forming a very special contrasting beauty.

A flock of birds was roaming over the lake. Occasionally a fish jumped out of the lake and was caught by the birds that had been waiting for the opportunity.

This beautiful scenery is the gift that the old man left to his descendants.

But human hearts are unpredictable, and behind a beautiful scenery there are more than a dozen lives hidden.

The master never imagined that his last words would cause fifteen years of tragedy for the Mamiya family.

His wife and daughter were brutally murdered, and his daughter's stone tower was labeled a forbidden place. The entire Mamiya family was basically in name only.

"So, when you leave a will in the future, it's best to make your words clear. Sometimes making things too complicated may not be a good thing."

Xiachuan shook his head and admired the entire sunset before going down to reunite with Conan and the others.

It’s time for dinner. After dinner, I still have to deal with the matter of the secret passage.

Ever since the incident with the Wind Goblin Bandit Group, he no longer fully believed in the plot, so he did not immediately expose the fact that Mamiya Shiro was someone else in disguise, in order not to alert the enemy.

Maybe she has accomplices, which is not impossible.

In the fire incident four years ago, a total of fifteen people died, including Mamiya Takato's mother. Natsukawa felt that Mamiya Dai might not be able to do all these things alone.

In short, be skeptical.

There are six children around me, and I am not afraid but I cannot put them in danger.

At the dinner table, the three generations of the Mamiya family lived together, and there were only three people left. One was the son-in-law and adopted son Mamiya Mitsuru, and the old lady Mamiya Dai was even a fake. Only Mamiya Nobuhito had the blood of the Mamiya family flowing in his veins. It was a bit sad...

At the dinner table, Nobuhiro Mamiya frequently looked at her stepfather, and the hostility in her eyes was very obvious.

"Dr. Agasa, after wandering around the castle for an entire afternoon, have you found anything?"

Mamiya Mitsuru didn't care about his stepson's attitude at all. He focused his attention on the treasure and looked at Dr. Agasa with burning eyes.

Can this extremely smart scientist give him the answer to the mystery that has kept him tossing and turning for four years?

Mamiya Takato and Mamiya Dai looked at each other sideways. They also wanted to know the answer, especially Mamiya Dai. Her gaze was even hotter than Mamiya Mitsuru's.

Fortunately, the reflection from her glasses helped her hide her gaffe.

Moreover, she was a little confused.

why?

These people clearly discovered and even opened the secret passage, but not only did they not go down to check the situation, they didn't even tell them.

Are these outsiders really here for the treasure?

She was also thinking about waiting for the other party to enter, and then taking advantage of their familiarity with the terrain, she would launch a sneak attack one by one and kill them all.

But these people don’t fall into the trap at all, which is a bit troublesome.

"Uh... well..."

Dr. Agasa looked around. He had followed Conan and the others for the whole afternoon. Although he found several places that might be secret passages, he could not imagine the so-called puzzle at all!

So, what is the connection between secret passages and chess?

Conan seemed to have guessed the secret of the chess set, but he didn't tell him, otherwise he could have used his extremely smart intelligence at this time.

"Didn't you solve this mystery either?" Mamiya Mitsuru was extremely disappointed. It seemed that he would have to go to Tokyo to ask Kogoro Mori to come and take a look at it as soon as the sun rose tomorrow. Only such a famous detective could solve the mystery left by his father-in-law.

"No, Dr. Agasa just thinks this puzzle is a little difficult. After all, you haven't solved it for more than ten years. It's obviously unrealistic for Dr. Agasa to solve it in one afternoon, right? Relax your mind, there will be an answer, and the treasure will definitely be found, but it will take some time."

Xia Chuan came to help out.

The others nodded when they heard this.

Indeed, even scientists cannot solve the mystery in an afternoon, and if they do, they will look stupid.

"In that case, let's have a good rest tonight. I hope Dr. Agasa can solve this mystery tomorrow."

Mamiya Mitsuru had no interest in the feast on the table. He only wanted to get the answer. After hearing Xiachuan's explanation, he could only nod and said, "If you have any questions, you can always come and ask me."

After saying that, Mamiya Mitsuru wiped his mouth gracefully, stood up and left.

"By the way, has Mr. Mamiya Mitsuru always been like this?" Conan asked curiously. This guy was a bit suspicious, but he shouldn't be the one blocking the door.

Not to mention whether the other party had enough time to run to the secret passage to block the door, just looking at the surprise and joy on his face when he heard about the secret passage, it was definitely not fake.

Mamiya Takato didn't answer. Instead, Mamiya Dai sneered and said, "Humph, this guy became our son-in-law just because he was attracted by our castle and the treasures left by the old man. He didn't admit it before, but now he finally reveals his true colors."

"Okay, grandma, let's not mention this anymore." Mamiya Nobuhito rubbed his eyes, believing that family disgrace should not be made public.

"I know. I'm full. My daughter should be back soon. When she comes back, ask her to come to my room to find me."

"Okay, okay grandma."

"I'm sorry, grandma became like this after mom's accident. Her memory is a little confused and she's not quite conscious. I'm sorry to have embarrassed you." Mamiya Takato sighed. This grandma is sometimes quite worrying.

Natsukawa quietly watched Representative Mamiya's performance.

In fact, Mamiya's acting is very poor. Although her expressions and movements are very similar, they do not fit the feeling of an old woman in her eighties.

However, I heard that Mamiya Mitsuru and Mamiya Takato only returned during the fire four years ago, and they may not know Mamiya Dai very well, so the other party was able to keep it a secret for so long.

But......

Xia Chuan suddenly discovered a bright spot.

I didn’t find any explanation for these two people, but what about the others?

Some of those servants might have been working here before the fire. It's impossible that they didn't notice anything at all, right?

Things are getting interesting. There is definitely her accomplice among the servants of the Mamiya family!

"It's okay. Every family has its own problems." Xia Chuan waved his hand to show his understanding.

The guests were still eating when two of them ran away from the host's house. The host had no hospitality at all. Mamiya Takatoshi seemed to have realized that his hospitality was not good enough and said with a smile, "Everyone, please eat quickly. Our chef is an expert at cooking and will definitely satisfy you."

"By the way, Mr. Guiren, I have a question for you." Conan interrupted, "Who is the most knowledgeable person in the Mamiya family?"

"Knowledgeable? If we talk about knowledgeable, I am the only one left in the family now." This is not just self-praise from Takato Mamiya.

He is a student who studied abroad and attended the top university in the United States. Although his major was fine arts, it is not an exaggeration to say that he had the highest cultural level.

My grandmother was just an ordinary college student when she was young. My stepfather has some money, but he is a nouveau riche and he never went to college. Now the entire Mamiya family lives on some business shares left by my grandfather.

"what?"

Conan's big eyes.

He believed that Mamiya Takato was knowledgeable, but when the other party's grandfather died, he was probably only a few years old. How could he be called an intellectual at that time?

wrong!

Conan suddenly remembered and realized that Takato Mamiya was talking about the present, and that it should not include those members of the Mamiya family who had died in recent years.

"Mr. Guiren, the people of the Mamiya family I'm talking about include your biological father, mother, and grandfather."

"Hmm?" Takato Mamiya narrowed his eyes slightly and paused in cutting the meat with his knife and fork, feeling that this question seemed not simple.

He looked at Dr. Agasa, then at Natsukawa.

Could it be that these two people have solved the puzzle and the answer to the puzzle is related to knowledgeable people?

If we have to say who is knowledgeable, my father, mother and grandfather all seem to be knowledgeable people. I heard that my father is my grandfather's disciple.

In this case, the person with the most knowledge should be my grandfather, right?

“In that case, my grandfather should be the one with the most profound knowledge in our family. This castle and family business were all built by my grandfather from scratch.

Dr. Agasa, is this question related to the chess puzzle?

Have you solved it yet? "

He suddenly slammed the table and asked excitedly.

"..."

Dr. Agasa blinked and made a few noises for a long time without saying a word.

“I see, it seems that you haven’t completely solved the mystery yet, but it doesn’t matter, I believe you can solve the answer.

I am the only bloodline of the Mamiya family. If Dr. Agasa solves the mystery, please tell me as soon as possible!"

Nobuhito Mamiya bent down and bowed 90 degrees, doing it in one go with a serious look on her face.

Obviously Mamiya Takato misunderstood, thinking that Dr. Agasa was pretending to be profound, or that the puzzle had not been fully solved yet, or that his extensive knowledge was related to the way of solving chess problems, but had not been fully solved yet.

"I understand. I will tell you as soon as possible!"

Dr. Agasa didn't understand, but it was no difficult to nod, and with Shinichi's intelligence, this case would definitely be solved easily.

They chatted for a few more minutes, and the dinner ended perfectly when the children were full.

"Have you guessed it?" On the way back to the room, Haibara Ai asked Conan in a low voice.

"almost."

Conan turned around and asked, "Uncle Xiachuan, have you solved the puzzle of this chess game?"

"what?"

"Hasn't it? You were away for so long this afternoon, wasn't it to solve the puzzle?"

Conan felt that Natsukawa might have found another way of thinking. Since he separated from them in the afternoon, he must have discovered something from other angles, which might be related to the secret passage.

If Xia Chuan could exchange some information with him, perhaps he could solve the secret of the treasure more quickly.

"No, I heard from Tian Yanshengnan that there is a lake behind the castle. I have been fishing by the lake this afternoon."

Although fishing was a lie, he did look at the lake for a long time, so it wasn't entirely a lie.

"Are you serious...?"

"Yeah, let's leave this mystery to your Junior Detective Team. I'm here on vacation." Xia Chuan muttered softly.

Okay, just pretend I didn't ask.

Conan rolled his eyes and asked, "When are we going to go into the secret passage to find out what's going on?"

Now Conan has learned his lesson and knows to take Natsukawa with him on adventures.

As I said, the enemy is in the dark and I am in the light. Conan is anxious to solve the case but does not want to die. It is safer to wait for Natsukawa to come together.

He lowered his head and took out a piece of paper from his pocket. It seemed to be a hand-drawn floor plan of the castle, with several places marked with different colors.

"These colored dots are possible entrances to secret passages. There are secret passages in some of the walls of this castle. Some of the secret passages are located on the second floor, and some are on the third floor. However, I suspect that they all connect to the underground in the end."

Conan stepped hard on the ground. Although it was solid, Conan firmly believed that there must be an unknown mysterious space under his feet.

"So, there should be a large basement underground. The so-called treasure is probably in the basement. I think the answer to the chess puzzle should be related to something in the basement."

Conan thought that the so-called something was probably an old man's relic or something like that.
