Conan started from the chat group

"I don't know, I just follow the instructions of the previous master, Master Zhenzhao, and organize it like this every day."

Tian Yansheng Nan paused, and then said: "I heard that Master Zhenzhao also obeyed the last words of the Grand Master who passed away 15 years ago."

"Predecessor? The one just now?" Dr. Ali asked in confusion.

"That's Master Man, Madam's second husband. As for Master Zhenzhao, he died of illness six years ago. Later"

Tian Yan Katsuo hesitated for a moment, and then slowly said: "Later, my wife also died in the fire four years ago."

"Fire?" Dr. Ali was taken aback.

"Don't you see a charred tower over there? Madam's bedroom is there." Tian Yanshengnan raised his finger and pointed to a tower in the distance.

When everyone looked over, they saw a dilapidated tower, with scorched marks on the surface, and only old stone bricks left to support the tower.

"It was not long after Madam came back to Japan to celebrate the old lady's birthday after many years. She arrived at the castle in the middle of the night, but before dawn, the tower caught fire," Tian Yan Katsuo said again.

"Is she alone?" Dr. Ali asked.

"It's not just Madam, even the friends who accompanied Madam and more than a dozen maids who served Madam Tai for a long time also died in the fire pit."

Tian Yansheng Nan sighed, and then said: "The only ones who survived the disaster are us servants who have been employed for a short period of time, Mrs. Tai who lived in Biejia because of the cold, and Mrs. Man who arrived earlier than Mrs. , and the one over there"

"Young Master Gui, the only son born to Madam and Master Zhenzhao".

Situ Xiu and the others looked in Tian Yansheng's direction, and saw a young man squatting beside a chess set, looking at something.

"Master Gui came back two or three days before the fire broke out. He has been studying abroad since he was a child. It was the first time I saw him back to the castle, and it was also the first time Master Man even saw him," Tian Yan Shengnan said.

"No way!" Situ Xiu was taken aback for a moment, his mother had a new love, and the son had never even met his stepfather.

"Since that incident, Master Man and Young Master Gui have stayed in the castle, as if possessed by a demon," Tian Yan Shengnan said again.

After hearing what Tian Yan Katsuo said, Conan squeezed his chin, and the detective's intuition told him that there must be some reasons for this.

Perhaps this castle holds treasure?

"I guess it has something to do with you," Situ Xiu whispered in Conan's ear.

"It's none of my business, you don't want to say you have a hunch again?" Conan pouted.

"Could it be that someone set fire to kill that lady and others, so that Master Man and Young Master Gui felt something was wrong, so they stayed and investigated secretly?" Situ Xiu asked.

"How many years did that happen, it's impossible"

Conan shook his head, and then said: "There should be some secrets in this castle, so these two people stayed."

"Treasure?" came a voice.

Situ Xiu looked over, not knowing when Hui Yuanai walked over.

"Maybe"

Conan nodded slightly, looked at the young man next to the chess in the distance, and then said: "The master of this ancient castle ordered future generations to take good care of the chess, so these chess should be clues."

Chapter 374 I Like to Chat with Xiao Ai

The young man who was watching by the chessboard was named Mamiya Takato, the son of the Mamiya family's daughter.

From Tian Yansheng Nan's mouth, I learned that there is a secret hidden in this ancient castle. As for what the secret is, no one knows so far.

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

However, from the master's last words, the secret may be related to chess.

In other words, in order to unlock this secret, one must first understand what codes are hidden in chess.

After watching chess, Tian Yansheng took Situ Xiu and others into the castle, and saw several portraits in the hall of the castle. One of the portraits was the Tailord, and on the left and right were his wife and Master Zhenzhao.

"Master Zhenzhao, who is married, respects Mr. Tai who is a historian very much. Our wife is often jealous of this, and said to Mr. Zhenzhao"

Tian Yansheng Nan was telling Situ Xiu and others about the relationship between several people in the portrait, but was interrupted before he finished speaking.

"She often said that Dad is just a reasonable intellectual." A voice came from behind everyone.

"Right?"

Tian Yansheng Nan looked back, and quickly called out: "Old lady".

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

This should be the dead Tailord's wife.

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

Hearing this, Situ Xiu thought to himself: "Of course, it's my own child after all, so I won't blame him no matter what I say."

Seeing what the old lady said, Tian Yan Katsunan scratched his head nervously, and said, "Sorry, I reminded 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's not around."

"It's like the size of the banknotes 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, all emotions will disappear with time"

Everyone was slightly taken aback, Situ Xiu pinched his chin and thought deeply, these words came from a mouth with dementia, no matter how you look at it, it feels a bit wrong.

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

"They are my master's scientist friends," Tian Yansheng Nan explained.

"the scientist?"

The old lady looked at Dr. Ali, and said, "It's really exciting. Be sure to ask them to unlock the code left by the old man."

"Code?" Everyone's expressions changed.

Seeing this, Tian Yansheng Nan explained: "It is the last words left by the Tailord before his death, saying that he will give his treasure to the person who unlocks the secret code of the castle."

"Oh." Dr. Ali nodded, it should be related to the chess game just now.

"By the way, my daughter hasn't arrived yet?" The old lady looked around and asked.

"Ah" Tian Yansheng was stunned for a moment.

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