Dr. A Li, who just went to the police, frowned and opened the door and walked in. Before Conan could ask, Dr. A Li said, "They said it might be a prank by a thief. They said that the day after tomorrow, they sent people to investigate here. ."

The three of them rummaged there and found the code. Just as Conan wanted to stop, Bu Mei took a playing card and said, "There is also a code on the back of this playing card!"

Conan, who was thinking about not disrupting the scene just now, changed his face instantly when he heard this, "Okay! Ayumi and I are in charge of the first floor, and Genta and Mitsuhiko will go to the second floor! Let's spread out!"

The three of them responded excitedly.

Dr. A Li looked at all this and squinted, "It's so fragrant!"

After a period of searching, a total of ten secret signs were found: playing cards, French dictionaries, records, toy airplanes, glass wine glasses, portraits and a puppet doll, as well as the plates, candlesticks, and vases found before.

"It would be great if there was a longer one that resembled an article." Conan squeezed his chin, "such as a diary or a letter."

Dr. A Li seemed to think of something, and said: "I remember, there is indeed such a letter!"

"For the past ten years, every year, a strange letter without the sender was sent to my aunt. My aunt felt something was wrong and asked me to discuss it. The content was written in hiragana instead of'Hello, teacher'. It's like'please take care of your body'."

"There are patterns around those hiragana greetings, which are painted like lace."

"What happened to those letters later?"

"If I don't understand it, give it to your dad..." Dr. A Li reacted as soon as he spoke, and said quickly, "I showed it to a mystery novelist who lives nearby. At first, this novelist has been prevarication because of work. I look uninterested."

"But after seeing the letter, he became more and more excited."

"He closed the door immediately after receiving the letter, and after a few minutes, he ran to me with the letter. He told me to give me a letter he wrote to my aunt, and then he described me as being like the sun. , Saying that his frustration was wiped out because of my blessing."

Yuan Tai hurriedly asked, "Is there anything special about that letter?"

Dr. A Li stroked his beard: "I'm not a person who likes to read other people's letters, so I didn't read it either. I don't know what's inside."

"It should be the interpretation table of the code." According to Conan's understanding of his father, Conan determined that the content of the letter was the interpretation table of the code. "The novelist must know that these codes represent all hiragana."

Conan nodded in the puzzled eyes of everyone: "The reason why all the new ones are written in hiragana is because the surrounding patterns must be interpreted in hiragana."

"The codes in the letter and the codes found here should be made by the same person. As for why the codes were used, it should be because no one wants to know the content of the letter. Maybe someone is persecuting him."

Dr. A Li seemed to think of something again: "I remember, my aunt did say that there is a strange guy who often peeks at her mailbox."

Conan also had speculation in his heart, and Conan became more and more interested in this villa with a mysterious secret.

After thinking about it carefully, Conan also had a clue, and quickly solved the pseudonym represented by the black sun. Following Conan's reasoning, Conan also made a solution table by guessing the word very smoothly.

According to the answer sheet, the codes on those items were quickly solved.

Following the prompts above, everyone found that there were still codes in the heater, and Conan followed the answer sheet to unlock the codes in the heater.

He didn't show any happy expressions when he unlocked the code. Instead, he was a little heavy. The code in the heater brought him back to the starting point.

Except for Conan, everyone thought that these codes were fake, just a prank by that person, but Conan didn't think so. He believed that there was no such boring person, except Guangyou.

Conan sat cross-legged on the ground thinking about the code.

Dr. Aka and the three of the detective team are putting all the items they found back to their original positions.

Naturally, Conan sitting on the ground blocking the way was rejected by everyone.

Suddenly, Conan's inspiration flashed. He found that all the things were found in this room. He connected all the things into a line according to the hint of the code. All the lines have an intersection at the center point, because there is such a The intersection point, so Ayumi will always pass by Conan.

It's a coincidence that Conan's location is the center point. Since there is no floor, then...

"It's on the ceiling!" Conan looked up at the ceiling, and he was pleasantly surprised to find a groove at the root of the chandelier on the ceiling.

Now that he has discovered something, he has to try it. Conan hurriedly greeted Dr. Ari: "Doctor, hurry up and put me on your shoulder!"

Although Dr. Aka was dumbfounded, he put Conan on his shoulder and saw Conan turn the chandelier. With a "click", there was a loud noise on the top of everyone's heads and the second floor of the villa, and there seemed to be heavy objects falling. On the floor of the room on the second floor.

When I went to the room on the second floor, I found that there was a ladder in the room. As a nephew, Dr. A Li didn't know that there was such a hidden mechanism in this villa.

Everyone walked up the stairs, and the group observed the entire secret room. They did not know what they saw. The three of the detective team had their pupils shrunk slightly, and they were sweating all over. The eye sockets of Step Mei were a little moist. Step Mei pointed to the next table and cried: "Here, there are dead human bones!"

Conan and Dr. Ari hurriedly ran to the table to observe. Conan, who had been at the crime scene for so many years, was not afraid at all. They were just moved to the table to observe.

According to his suspicion, it is estimated that the dead man was an old man who engraved coins. When he died, he died while writing a letter to Dr. A Li's aunt.

Dr. A Li was a little confused: "How did this person know about this secret room?"

"He should be the painter of that oil painting. As for why he hides here, it is probably because of this."

Conan took out something from behind and threw it to Dr. Ari.

When Dr. A Li took a closer look, he was a little surprised: "The lead sheet of 20 dollar bills? This is used to make counterfeit bills!"

Conan nodded: "Someone asked this painter to do it, but then I don’t know why the painter changed his mind. It should be hiding here to escape the chase of that person. It should be sent to your aunt for thanks. The code is Because I don’t want that person to know that he lives in this place."

"The one who often looks at her mailbox should be the one who asked him to make counterfeit money, and he should be the one who broke the toy."

"Boy, your reasoning is very beautiful!" A man's voice reached everyone's ears, "I came here and finally found the box. I thought it was a lead plate, but all I saw were toys, so I I poke them all in a fit of anger."

"When I knew that he had a good relationship with the owner of this villa, I kept looking for it here, but I didn't expect that there would be a secret room here."

"Thank you, kid!"

The man walked up the stairs, pointed a gun at Conan and his group and threatened: "Hurry up and give me the lead plate. Although I have a gun, I don’t want to kill. If you don’t listen to me, you might wipe the gun. Go away!"

Suddenly, the man's pupils shrank slightly, his throat fumbled and he fell to the ground.

Only a familiar voice came from behind him: "I am so cute to let you go!"

Everyone was very surprised when they heard the voice: "Guangyou!"

Behind him was Guangyou, who had been missing for a long time. Guangyou's face was a little impatient: "I am playing hide-and-seek with you? You give me a blind hammer to run around? Is it fun?"

The man lying on the ground widened his eyes and wanted to raise his gun to shoot. Guangyou naturally did not give him this opportunity: "Want to resist? Look at my messy cloak legs! Courgettes and eggs!"

Guangyou raised his leg and kicked between the man's legs, one foot was harder than the other, and all the boys present felt painful.

Everyone felt distressed for the man.

Seeing the man on the ground staring, spitting white foam, and convulsing his whole body, Guangyou "cut" disdainfully: "I'm pooh."

After solving the man, Guangyou raised his head and asked everyone, "Are you okay?"

"Where have you been before?" Conan asked, looking at the sudden emergence of Guangyou.

Guangyou explained: "At that time, I noticed that there were other people nearby, and I went out to check, but the rammer kept going around me and playing hide and seek with me."

"Why don't you tell me?"

"Is it useful to tell you? It's not against whom I am targeting, none of you can fight!"

Although Guangyou's words sound very arrogant, but they have to admit it, indeed.

An old man, four young children, the fighting power is infinitely close to zero.

Conan pointed to the man still twitching on the ground: "You are too cruel!"

Seeing the man on the ground, Conan's crotch felt cold.

Guangyou said solemnly and solemnly: "If you hesitate, you will lose! What's more, I have no weapons. Can I jump up and hit him in the head?"

Conan could not refute: "enmnm."

This time the BOSS was already lying on the ground. Conan looked at the entire secret room with confidence. In the secret room, there was a covered painting. After seeing it, Conan asked: "Doctor, what happened to your aunt?"

"Already passed away last year, at the age of 76, she has never been married in her life."

Hearing Dr. A Li's answer, Guangyou hummed casually: "Whose lover is again~"

On the way home, Dr. Ari frowned: "After that happened, your father has been calling me Dr. Sun for a while. I don't know why, Conan, do you know?"

Conan laughed when he heard it: "Of course, doctor, you look at the answer sheet, your name is all the pattern of the sun."

"Hahaha!" The mystery in my heart was solved, and it was so interesting, Dr. A Li burst out laughing: "You can also call me Dr. Sun in the future!"

Guangyou sat in the back seat and said quietly, "Okay, Dr. Ri."

Dr. A Li corrected, "It's Dr. Sun!"

"Okay, no problem! Dr. Sun!"
