Conan: Another Famous Detective

The speaker was the old woman whom several people had met on the first floor of the castle.

When Mamiya Mitsuru heard what the old woman said, his expression stiffened, and then he laughed and said, "That's true. If you really don't care about your father-in-law's last words, it's impossible."

The old woman opened her eyes slightly, glanced at Mamiya Mitsuru with her cloudy eyes, and snorted coldly: "I knew that my daughter was deceived by a greedy man like you!"

The old woman turned the wheelchair in the direction and said calmly: "I'm going back to the room to have dinner. When my daughter arrives, I will bring her here. I must talk to her well!"

After saying this, the old woman also left the restaurant in her wheelchair.

"Grandma is still like this...she always thinks that my mother is still alive." Takato Mamiya said with a complicated expression.

"Yeah, her memory is getting worse and worse. After all, she hasn't left the castle for ten years..." Mamiya Mitsuru said this and looked at Dr. Agasa:

"By the way, is the mystery solved?"

"Ah? A puzzle?" Dr. Ari was stunned, and then glanced at Akira Hanomiya, who was sitting on the left, and Conan, who was sitting on the right.

"Yes, I think you should have listened to Tabata, right?" Mamiya Mitsuru continued to ask.

"Uh... well..." The doctor didn't know how to answer for a while. He was not the one who really knew how to solve puzzles!

"Chess." Yu Gongming's calm voice helped the doctor.

"Oh? Mr. Kazama, what does this mean?" Mamiya Mitsuru asked.

"The chess pieces in the front yard of the castle were something that the great master liked very much. And when you look down from the third floor of the castle, you can see that the chess pieces on the chess board are arranged in many meaningful patterns."

"I think this should be the only thing in this castle that can be called a mystery, right?"

"So, has Mr. Kazama solved the mystery of chess?" Mamiya looked at Hanomiya Akira expectantly.

"Unfortunately, I am not good at such puzzles, but I think the pattern of these chess pieces seems to be some kind of matrix. This doctor has more say in this aspect."

Akira Yumiya threw the question back to the doctor.

This time, the doctor was smarter and said immediately: "Matrix analysis like this requires a lot of time to calculate. I have only been here for an afternoon and I have to take care of these children. I have no time to solve puzzles!"

A look of disappointment flashed across Mamiya's face, but the next moment his expression returned to normal, and he chuckled:

"I see, can you please ask the doctor to stay here for a few more days and help us solve the mystery left by my father-in-law? After we find the treasure, we will naturally not treat you badly."

"Uh, but these kids..." Upon hearing this request, the doctor immediately began to find reasons to refuse.

"It's okay, I'll have someone send them home, or I can notify their parents and let them play here for a few more days."

"This castle is quite big. Children can play around as they like. When they are tired, they can go to bed directly. No problem!"

"Ah, but..." Dr. Ali wanted to say something more, but Yu Gongming's voice suddenly sounded:

"Doctor, with your knowledge, there will be no problem. I can also help with some calculations when the time comes."

Dr. Agasa glanced at Akira Hanomiya hesitantly, and after seeing him nod slightly, the doctor looked at Mitsuru Mamiya:

"Okay, I can stay here for a few days, but I need to call the parents of these children tomorrow to find out whether to send them back or keep them here."

"That's great, then it's been hard work these days, Doctor!" Mamiya Mitsuru said with a face full of joy.

"Where there..." The doctor showed an awkward but polite smile, but in his heart he was silently praying that Yu Gongming would never cheat him!

Conan glanced at Hanomiya Akira: "This guy is obviously talking nonsense, right? Judging from Tabata's description, this old man should be an old scholar with some research on literature and history. It really doesn't seem like he can use numbers. The Matrix is ​​the one who set up the secret code, right?”

"Forget it, we should be able to find a lot of clues tonight. We don't really need to stay here for a few days. It doesn't matter if we agree."

Conan put these messy thoughts aside for the time being and continued to enjoy the delicious dinner.

"By the way, everyone's rooms have been tidied up. I will take you there later." Mamiya Takato said with a smile.

"Ah! That's troublesome." Dr. Ali thanked him.

Not long after, the group finished their dinner, and under the guidance of Lord Mamiya, they came to their rooms.

There are many empty rooms in the castle, and the rooms for the group are all next to each other, either adjacent to each other or facing each other.

"This castle is really big, and it's connected in all directions, like a maze!" Mitsuhiko sighed.

"Yes, this castle was designed by my grandfather in the style of a traditional European castle, and there are many mechanisms in the castle. You must be careful, some of the mechanisms are very dangerous!" Takato Mamiya reminded seriously. road.

"Yes! We know!" The three little ones responded loudly, but from their twinkling eyes, Yu Gongming was sure that they must be thinking about going to a castle to adventure or something.

Lord Mamiya turned to look at Akira Hanomiya: "Kazema, you don't mind catching up on old times, right?"

Yu Gongming smiled slightly: "Of course, why not come to my room, and Xiaofeng can come too."

"Okay! I also want to meet Senior Mamiya!" Meng Yu said with a smile.

"Then let's go!"

The three of them entered the room assigned to Yu Gongming together.

However, when Yu Gongming was about to enter the room, his calf seemed to be itchy, so he bent down and scratched it twice.

Then, he stood up again, put the button-type bug in his hand into his pocket, and then closed the door.

Conan pushed up his glasses slightly, smiled slightly, and entered his room with the others.

In Yu Gongming's room.

"Detective Hanomiya, have you gained anything so far?" Takato Mamiya asked.

"I did find some doubts, but many things are still unclear." Yu Gongming said calmly.

"Oh? What's the suspicion?" Mamiya Takato's eyes lit up!

"That's your grandmother." Yu Gongming replied:

"According to Tabata, she hasn't left the castle in ten years, but when she was reflecting on life, she mentioned the change in the size of her passport."

"Changes in passport size? What does that mean?" Mamiya Takato was confused.

"The change in passport size happened six years ago. If she really hadn't left the castle for ten years, how would she know that the passport size had changed?"

"People like you and Mr. Aman who have been living abroad before should still use the old passport, and it has the same validity as the new passport."

"So, you may not notice the change in your passport, as you can tell from your reaction just now."

"So, how did your grandmother know about the passport change?"

"With news like this, if she hadn't applied to leave the country after changing her passport, it's unlikely that the eldest lady, who hasn't left the castle in ten years, would have known about it."

Mamiya Takato said with surprise on his face: "But...grandma's feet are injured like that. How could she go abroad without us knowing about it?"

Yu Gongming's expression condensed slightly, and he said quietly: "Then what if...this person is not your grandmother at all?"
