"Will we be killed? I don't want to die yet."

"Maybe it's the monster that is boarding in this forest, I don't want to be eaten."

"I also want to eat a lot of eel rice." Azumi and the other two were about to cry.

Some people have said that death is not terrible, and waiting for death is the most terrifying thing. Now this is what Emperor Wu and others are like.

Even though they knew the prisoners were hiding around, they didn't know when they would appear and whether they would attack them, but they couldn't do anything and could only hide in the villa and shivered.

Emperor Wu saw the atmosphere in the room becoming more and more depressing, and the children's emotions became very unstable, and he felt that this could not continue.

"Didn't you say you were looking for a treasure before? We can't leave anyway, so we can find a way to untie the secret code and see if it is a treasure." Emperor Wu said.

"Yeah?" Emperor Wu's words successfully attracted everyone's attention.

"However, everyone cannot separate, they must act together." Emperor Wu continued.

After all, Azumi and others are children, and their attention is easily diverted, especially treasure hunting. As they search for clues everywhere, they quickly forget about the prisoner's affairs and are no longer afraid.

After some search, I finally found several items with the patterns of sun, moon and stars, including playing cards, French dictionaries, records, airplane models, wine glasses, oil paintings, machine dolls, plates, candlesticks and vases, a total of ten things.

"Although I have found so many things, I still don't know what these codes mean." Azumi squatted down and said.

"Well, these codes are too short. If they are longer, such as articles, diaries or letters written with codes," Conan strodes.

"Speaking of this, I feel that these patterns look so familiar, and I seem to have seen them somewhere," Dr. Agasa thought.

"Ah! I remember, my aunt showed me before, and that happened several years ago, just the girl in the oil painting. She said that ten years ago, there would be a seal every year without the sender or address. The letter with the name was sent to her, and the contents in the letter were written in Hiragana."

"Around the letter, it was like the lace of the picture frame, and many patterns were drawn, using similar patterns," recalled Dr. Agasa.

"I understand!" Conan looked at the code written in the notebook, and listened to the doctor's words, and a flash of inspiration flashed in his mind.

"These secret codes are all Hiragana. The letters to the doctor's aunt are not Hiragana. They are intended to use Hiragana to interpret the secret codes around them. It seems that those letters and those who leave these secret codes should be the same person." Conan said.

"However, why did that person write to my aunt?" Dr. Agasa was puzzled.

"This is a question. It must be something that people other than your aunt don't want to know about." Wu Di said while playing with the record with a code engraved.

"By the way, I remember my aunt once said that someone often steals her letters," said Dr. Agasa.

"However, even if you know that these codes are Hiragana, you don't know what these codes mean." Ayumi and others said depressedly.

"It's very simple, just find out the rules," Conan said, and took out a pattern as an example.

Dr. Agasa and others seemed to understand some rules when they listened to Conan's words, but only Emperor Wu didn't understand a single word.

When Emperor Wu learned Japanese, he was deeply distressed by Hiragana. He still half-understands such as voiced and semi-voiced things. He often made mistakes and was ridiculed by a certain vicious pseudo-loli.

With the joint efforts of Conan and the Youth Detective Group, the secret code cracking work began. Emperor Wu watched the whole process and could not help at all.

After cracking the meaning of the code, the code on the item is quickly interpreted, which is a hint to find the next item. The code on the plate means looking at the vase, the code on the vase means looking at the candlestick and so on.

Everyone has found all the items that record the code. The last item to find the prompt is playing cards, and the code on the poker finally points to the stove.

"The treasure is in the fireplace? But we have looked for it before, there is nothing in the fireplace, it is empty inside." Yuan Tai said in confusion.

"There's something here!" Conan crawled into the fireplace, looked carefully with the flashlight, and found a secret code on the floor.

"!!" After interpreting the code in the fireplace, Conan was silent.

The code in the fireplace points to the first dish, and returns to the original starting point, which becomes a vicious cycle.

"Oh, is this code just a prank?" Everyone was very unwilling to accept it when they heard Conan's words.

"No, something must have been missed, and something else I didn't notice."

"Is it the first letter of all words connected? Roman characters? French? English? Or German?" Conan looked at the code written on the paper and fell into deep thought. Once he entered this state, he would not be affected by the outside world unless he specifically called him.

"Don't worry about him, put all the things back and restore the scene to the original state so that the police can find the prisoner when they arrive." Wu Di ignored him and said to everyone.

"Doctor, where should this aircraft model and playing cards be? "Asumi asked.

"Oh, the plane turned out to be next to the vase. I took it to the bedroom. The playing cards were also from the pile of playing cards on the table." Conan said.

"Wait, these items with codes are all things in this room?" Conan's ears moved and suddenly looked up and asked.

Conan immediately took a pen and drew on the notebook, drew the layout of the entire room, and then drew various pictures with codes. He used lines to link them in order and found that the intersection of the lines happened to be the center of the room.

"Have you unlocked the dead cycle of the secret code?" Emperor Wu came over and said as he looked at the picture drawn by Conan.

"Is there any secret in the middle of this room?" Conan lay on the ground and searched carefully.

"I think I might find what the code refers to." Wu Di said.

"What!?" Conan immediately looked at Emperor Wu.

Emperor Wu reached out and pointed to the top of his head. He saw the chandelier on the ceiling above their heads. Looking carefully at the base of the chandelier, there was a slender mark on it.

"Ka" fiddled with the chandelier and found that the chandelier could move. When he turned the chandelier, he heard a strange sound.

‘Bang!’ The sound of heavy objects hitting the ground suddenly sounded, which scared everyone.

"It's the second floor!" After breaking the secret code, everyone ran to the second floor excitedly.

When I arrived at the room opposite the second floor, I saw an extra staircase leading to the attic.

The code points to a chandelier, which is the mechanism for turning on this hidden staircase.
