The young man who was observing next to the chess was named Takato Mamiya, the son of the daughter of the Mamiya family.

I learned from Tian Yanshengnan's mouth that there is a secret hidden in this ancient castle, and no one knows what the secret is.

Because the old lady has Alzheimer's disease, and the old man has also died, no one knows this secret.

However, from the last words of the old man, the secret may be related to chess.

In other words, in order to solve this secret, you must first understand what code is hidden in chess.

After watching the chess, Tian Yanshengnan took Situ Xiu and others into the castle, and saw several portraits in the hall of the castle, one of which was the old man, and the left and right sides were Mrs. and Master Zhenzhao.

"Master Zhenzhao respects the old man as a historian very much, and our wife is often jealous of this, and says to Master Zhenzhao....."

Tian Yan Shengnan was telling Situ Xiu and others about the relationship between the people in the portrait, and was interrupted before he could finish speaking.

"She used to say that Dad was just a reasonable intellectual," a voice came from behind the crowd.

"Right?"

Tian Yanshengnan looked back and hurriedly shouted, "Old lady..."

Situ Xiu and the others turned around and looked back, and saw an old woman in a wheelchair, with gray hair, a wrinkled face, and an old face.

This should be the wife of the dead old man.

"The child's father also knows about this, but he is not angry at all when he hears this, but is very happy!" The old lady said.

Hearing this, Situ Xiu secretly said in his heart: "Of course, after all, it is his own child, and he will not blame him no matter what he says."

Seeing the old lady say this, Tian Yanshengnan scratched his head nervously and said, "I'm sorry for reminding you of something unpleasant."

"No need to apologize"

The old lady looked at the portrait in the middle of the hall, and said, "I'm used to the days when he wasn't around."

"Just like the round case of the banknote and the size of the passport have changed, you will not get used to it at first, but you will get used to it after a long time."

"Time is terrible, and all joys, sorrows, and sorrows will fade with time"

Everyone was slightly stunned, Situ Xiu pinched his chin and thought deeply, these words came out of the mouth of a person with Alzheimer's disease, no matter how you look at it, it feels a little wrong.

"By the way, who are they?" The old lady turned her head to look at Situ Xiu and the others.

"They're my master's scientist friends," Tian Yan explained.

"Scientists?"

The old lady looked at Dr. Asasa and said, "It's really exciting, I must ask them to unravel the code left by the old man."

"Cipher?" Everyone's expressions moved.

Seeing this, Tian Yan Shengnan explained: "It is the last words left by the old man before his death, saying that he will give his treasure to the person who unlocked the secret code of the ancient castle."

"Oh...."Dr. Asasa nodded, it must have something to do with the chess game just now.

"By the way, my daughter hasn't arrived yet, has she?" The old lady glanced around.

"Ah...."Tian Yanshengnan was stunned for a moment.

"Isn't she coming back today to celebrate my birthday?" The old lady continued to ask.

"......" the crowd.

Is this Alzheimer's onset?

"When I came back, I told her to come to my room immediately, I'm waiting for her!" The old lady said, turned the wheelchair with both hands, and slowly left.

"Ever since the tower caught fire, the old lady has been ..... like this," Tian Yansheng said.

"Probably quite irritated!" Dr. Asasa said.

Looking at the departing old lady, Situ Xiu frowned slightly and said, "It's so strange."

"What's weird?" Gray Yuan on the side asked.

"Isn't she a little senile? But just now, it seems that the memory is so good, but he forgot about the death of his daughter," Situ Xiudao.

"Haven't you ever met someone with Alzheimer's," Gray Yuan lamented.

"Does it count if you've seen it on TV?" Situ Xiu looked at Gray Yuan and mourned.

"....." Gray Plains mourns.

Situ Xiu pursed his lips, he has never been in contact with people with Alzheimer's disease so far, he has only seen written introductions, and people with Alzheimer's disease are staged on TV, anyway, people with this disease don't remember anything.

"If she had Alzheimer's because she had been stimulated by that fire, she might have stuck in her memory and didn't want to remember the person who died, or she didn't want to believe that the person was dead," Ashbara lamented.

"Forget it, don't dwell on this, it has nothing to do with us anyway" Situ Xiu said with a faint smile.

"You brought it up, okay!" Gray Yuan glanced at Situ Xiu sadly, and said what Alzheimer's disease was, when he was old, all kinds of diseases came.

"emmm....." Situ Xiu's face was speechless, the teacher had taught him, if he didn't understand, he was still a child.

Conan was very interested in the code that the old lady said, and guessed that it might be related to chess, so he asked Tian Yan Katsuo where he could see the chess in the courtyard from the room in the castle.

The group was taken by Tian Yan Shengnan to a certain room in the ancient castle, and from the window of the room, they saw the chess in the courtyard below.

"Wow, that's great! From here, you can see that the chess pieces are arranged so neatly! ”。

"Where? I can't see! ”。

"Yuantai, don't squeeze!".

The three bear children shouted, all huddled in a window.

"Why squeeze into a window, isn't there a window in the next room?" Situ Monastery.

"That's right!" Yuantai's eyes lit up, and he immediately ran to the window of the next room.

"Wow, you can see it from this room."

Mitsuhiko heard Motota's voice and ran over as well.

In this room, only Ayumi remained at the window, and Conan sat on the floor and took out a pen and paper and drew something, his face deep in thought.

"Don't you want to unlock the code?" Gray Yuan looked at Situ Xiudao on the side.

"Isn't there a guy who is solving it?"

Situ Xiu stretched out his finger and pointed at Conan, then looked at Gray Yuan and said, "Besides, I'm not interested in detectives, I like to chat with Xiao Ai."

Gray Yuan mourned for a moment, looked at Situ Xiu for a few seconds, a trace of color flashed in his eyes, and slowly said, "What are you thinking about just a child."

If it was the gray plain mourning in the past, he would say cold words directly, I don't like to chat with you, and I don't like little children.

"Uh..... I didn't think about anything, I just wanted to talk to you, can't I? Situ Xiu pretended not to understand.

"That's all?" Gray Yuan's eyes widened, is her thinking not pure?

"What else?" Situ Xiu's big eyes looked at Gray Yuan's mourning, pretending to be at a loss.

"Uh....." Gray Yuan Wai was speechless, chatting with Situ Xiu, always feeling that he was not chatting with a child, so he unconsciously entered another state, and did not treat him as a child.

"Hey, what are you two doing, it's going to fall like this"

Ayumi, who was lying by the window, suddenly shouted.

When Conan heard this, he quickly got up from the ground, leaned on the window and looked outside, his face changed, and said, "This stupid."

I saw that outside the window of the next room, Yuantai didn't know when he turned out of the window and went outside, and Mitsuhiko pulled Yuantai tightly with both hands.

"Mitsuhiko, don't let go!" Yuantai's face changed in fright, and there was a courtyard below, and if it fell, it would become a meatloaf.
