What's wrong with me who owns the system in Conan?

"I remember that it should have happened five or six years ago. In the past ten years, a strange letter with no sender has been sent every year. Auntie Dingzi felt something was wrong and asked me to discuss it." Dr. A Li caressed He rubbed his chin in thought.

"The content inside is all in hiragana, and it's all about hello teacher or please take care of yourself."

Yuan Tai thought for a while and asked, "Could it be a letter sent to her by a student?"

"But the letter has been using hiragana for ten years!" The doctor also said puzzled.

"It's really strange to say that!" Xiao Ai was also thinking about the key point.

"Then what is the relationship between the code and those letters?" Conan looked at the doctor with some confusion and asked.

"Oh~ Those letters are surrounded by pictures, just like lace."

"And then? What happened to those letters?" Conan asked.

Dr. A Li thought for a while, "Then I showed it to your father... No, I showed it to a mystery novelist next door."

"Ah! Show it to my dad!" Conan thought in his heart.

"The novelist was not very interested in this at the beginning because of his work, but after he read the letter, he became more and more excited!"

"Then he asked me for the letter and closed the door immediately. After a while, he came to my house again and told me so!"

"I would like you to hand this envelope to your aunt. To be honest, I am so happy. Doctor, you are like the sun. Thanks to you, my depression has been swept away!"

"Is there any mystery in that envelope?"

"I do not know!"

"The envelope must contain a code interpretation table. That's right, because the novelist must also know that these codes represent all hiragana characters!"

"Hiragana?"

"Is it true? Conan!" Yuan Tai asked.

"Yes!" Conan nodded, "The reason why those letters are all written in hiragana is because the patterns painted around must also use hiragana to read the key."

"Oh, that's it!" Dr. A Li seemed to have understood something.

"Then the person who sent the letter should be the one who drew the code?" Feng Yuan asked with a smile.

"Well, that's right. From these signs, they should be the same person." Conan said solemnly.

"Then why did this person send a letter to my aunt?" asked the doctor.

"Because he doesn't want anyone other than your aunt to understand, and maybe someone is trying to harm her." Conan looked up at the doctor and said.

"Yes, I remembered." The doctor smacked his forehead, "My aunt did say that there are always people hovering in front of her mailbox to peek."

"Maybe this person is the gangster wandering nearby." Feng Yuan said with a smile.

"However, even if we know that these codes are hiragana, it's useless?" Mitsuhiko said in frustration.

"It's okay, I think it's okay as long as there is a beginning, for example, the black moon, stars, and the white sun, moon, and stars have a few slightly different shapes!" Feng Yuan smiled and took Take a vase and turn it to the bottom, and show it to everyone.

"Only the black sun does not change, and in hiragana, it does not belong to any paragraph or line, and I think the only word that does not have the same attribute is ん!"

"The black sun represents ん, right?" Mitsuhiko understood.

"That's right." Feng Yuan looked at everyone and nodded, "And the last three symbols on the right side of all items are the same, so they can be interpreted separately from the previous ones."

"Oh, so that's the case!" Dr. A Li exclaimed, "I didn't expect that Fengyuan's reasoning is so good!"

"After all, I am also a detective!" Feng Yuan said with a smile, "Besides, there will be a black or white dot in the upper right corner next to some graphics, I think that should represent voiced and semi-voiced sounds."

"Yes, brother Fengyuan." Conan nodded in agreement, and then looked at the crowd and said, "Let's look at this first-quarter moon with an upward angle, there are three types with black dots, white dots and nothing added. That is to say, this kind of first-quarter moon with an upward angle represents a certain letter in the ha row!"

"That's right, because only the letter ha can be added with voiced and semi-voiced sounds!" Mitsuhiko said in surprise.

"Yes, according to this rule, the easiest part to decipher is the code drawn on the glass." Conan picked up a glass and said.

"Remove the other four words from the three on the right, the third black sun is en, the fourth is a word in the line of pa, which is composed of four letters, and there are consonants in the line of en and pa in it? said Conan.

"Pants, barrettes..."

"Cantaloupe Bread, Curry Bun!"

"Personal computer, playing cards..." Mitsuhiko said with his eyes brightened suddenly, "It's playing cards!"

"That's right, then this must be about a desk lamp." Ayumi said happily while holding a wine glass.

"Wait a minute!" Conan's head cleared for a while, and then he turned over the candlestick beside him, "Then this is the propeller?"

"And if this black first quarter moon is ro, pay attention to the propeller! It's not wrong, that's it!"

Yuan Tai picked up the plane and turned it over to have a look, "The code on the plane is really written on the back of the propeller!"

"Really!" Mitsuhiko also leaned over to look, "If the black dots in the upper right corner are cloudy dots, then the second word is bu, and the third word is ra... Then the combination is, pay attention to the oil painting!"

"By the way, I understand that this code is placed on some things in the villa, and a word of attention is added, so just read it slowly in order!" Conan looked at everyone and said with a smile .

"At that time, I will know what the thing that was not hidden by the code is!"

"Really!"

"Let's work together to solve all these codes and see what the treasure is!" Yuan Tai cheered.

"it is good!"

"Hmm~ The third character of the sign drawn on the plate is en, and the second character is a letter with cloudy dots, vase, it's a vase!" Ayumi said happily while holding the plate.

"The code in the dictionary is a stove!" Yuan Tai shouted.

Mitsuhiko took the puppet doll and tried hard to crack it, "Then this is a wine glass!"

"Hey? Conan, what are you doing?" The little ones shouted in confusion when they saw Conan running aside.

"I'm writing this, look!" Conan put down his pen, and then handed the written paper to everyone, "This is the code interpretation form."

"Wow, it's amazing!" Ayumi said in admiration.

"In this way, we can know the different changes caused by the rotation angle of the sun, moon, and stars. As for the black dots in the lower right corner, they were added because of insufficient changes." Conan explained for everyone.

Feng Yuan watched from the sidelines and was very convinced. Now in terms of reasoning, it seems that he will not be able to catch up in a short time. He can only reach his level when he strengthens more in the future.

"Pay attention to vase→candlestick→propeller→oil painting→record→puppet doll→glass wine glass→playing cards→dictionary→stove"

"Stove, it's a stove!"

The children cheered, and even Conan ran to the stove in excitement.

"What? Pay attention to the plate again!" Everyone was a little disappointed.

"What, now we have to do it all over again." Yuan Tai got up dissatisfied and said.

Mitsuhiko was also a little disappointed, "We are simply being played around by secret signs!"

"No way?"

"This prank is too much!" The doctor was also dissatisfied.

"It's not a prank, is it?" Feng Yuan said, "Have you considered connecting through the original location of these items to see?"

"Ok?"

Hearing this, Conan was startled, he quickly reset all the items in his mind, and then connected them one by one with lines.

"It's here!" Conan stood in the center of the living room and stomped his feet, "No, there's nothing underground here!"

"Could it be..." Conan looked up, only to see a golden chandelier above his head.

"Dr. Ali, let me lift it!" Conan said eagerly, then climbed onto his shoulders and turned the chandelier!

"boom!"

As the chandelier turned, a loud sound came from the room on the top floor!

Everyone went up to the second floor, only to see that a chained staircase had been lowered.

"A new space has opened!"
