"Brother Zhenyu, the code of music score is to put the English letters in order from the left of the piano keyboard, and then translate the meaning you want to convey into music score in pinyin."

"According to this method, to read the music score at the scene of Mr. Kawashima's murder is this sentence [understand? The next is you!], and the music score information in the radio room is [the resentment of sin is eliminated here, and the last sin is myself!]."

After Conan told Bai Yan Zhenyu the interpretation method and content of the score code, his face changed and he said eagerly, "no, the prisoner wants to commit suicide. We should stop him quickly."

"I see, Conan, leave it to me."

Seeing that Conan had indeed interpreted the code, Baiyan Zhenyu flashed a slight but undetectable smile around his mouth, and then told these clues to police officers and others at dusk.

After hearing these two words, many people's faces changed. Secretary Hirata said in horror, "the resentment of sin... Doesn't mean Mr. ASO who committed suicide 12 years ago."

Xibenjian, who killed the ASO Keiji family, was a little collapsed and shouted, "ha ha ha, it's that guy. ASO Keiji is still alive. He's coming for revenge."

"How can it be? Guiji Aso is indeed dead."

The old policeman, who had been making soy sauce, said: "the skull and teeth were found at the scene of the fire. They have been compared by professionals. It is absolutely right for their family. At that time, all things were burned, and only the music scores put in the fire safe are still preserved."

"What? And the music score?" the police officer looked happy at dusk and hurriedly asked, "where is the music score?"

"Ah ha ha, that..." the old policeman smiled awkwardly, touched his head and said, "I remember it seems to be in the warehouse of the citizen's Museum, but the key of the warehouse was put in the police station."

At dusk, the officer waved his big hand and urged, "don't take it quickly."

"Yes, I see." the policeman gave a flustered salute, and then ran to the police station on Yueying island.

"Wait a minute, police Grandpa, I'll go with you." Conan wanted to find more clues and left with the police man.

"Conan, wait, really, Dad, I'll go and have a look too." Xiaolan was worried. Conan said to Maoli xiaowulang and chased them in the direction they left.

At this time, it was more than 7 p.m. and everyone felt a little hungry. At dusk, the police officer had to allow them to leave and return here after dinner to continue the investigation.

After dinner, they went back to the citizen's hall one after another. Only Xiben Jian and Conan, who went to find the key, had not returned.

When the police officer saw this at dusk, he had to send his men out. Some people went to the hotels on Yueying island to find xibenjian, while others went to the police station to see Conan and their situation.

However, before the people sent out came back, the last movement of moonlight sounded again in the citizens' Pavilion.

"No, go and have a look."

At dusk, the police officer and Maori Kogoro changed their faces and ran in the direction of the music. They found that the music came from the warehouse of the citizen's Museum.

In the face of such a situation, the dusk police officer made a quick decision and said, "I can't manage so much. Just knock the door open!"

"Bang!"

The wooden warehouse gate was easily knocked open by police officers and Maori Kogoro at dusk. The scene inside suddenly fell into the eyes of everyone.

"Ah!!!"

Seeing xibenjian commit suicide by hanging a beam in the room, Heiyan chenci's daughter screamed, fainted in an instant, and then was hurriedly helped aside by his fiance to rest.

At dusk, the police officer and Maori Kogoro entered the room, checked the radio that stopped playing music, and judged: "as before, it is also a single-sided thirty minute tape. It seems that Mr. Xiben died half an hour ago."

Baiyan Zhenyu, who followed behind them, pointed to the ground below Mr. Xiben and said, "at dusk, the police department, uncle, a pile of music scores appeared at Mr. Xiben's feet."

"What, let me see."

Maori Kogoro picked up the music score, interpreted the above information according to the method Bai yanzhenyu told them before, and found that it was a suicide note left by xibenjian.

In his suicide note, xibenjian explained that the five of them sold "washing powder" together and set fire to his family after Aso guier chose to quit.

After making this crime, xibenjian's heart was tortured and tortured for many years. Unable to bear it, xibenjian decided to make atonement with his own life. After killing his accomplices who committed the crime together, he finally chose to hang himself.

Finally, xibenjian also explained that Secretary Hirata and Hideo Kawashima continued to trade in "washing powder" and hoped that the police would bring him to justice.

After reading the contents of the suicide note, Mao xiaowulang sighed: "at dusk, the police department, it seems that the case has been clarified. The murderer is xibenjian."

"Yes, I didn't expect that Mr. Aso's family was killed by their companions." the police department also sighed at dusk. I didn't expect that there was such a secret in the case 12 years ago.

At this time, Conan returned to the scene with the key. He was surprised to learn that xibenjian admitted that he was the real murderer behind the scenes and hanged himself.

Conan also deduced from the clues what had happened that year. He doubted xibenjian's "confession" and decided to go to the scene.

"Well, there's no problem with the code on the tape and music score. Moreover, the second music score information mentioned suicide. There's no sign of struggle on his body. There's a tilted chair under his feet. It seems that he did hang himself."

Different from the original work, Conan did not find the slightest flaw. Combined with the clues collected before, he did not suspect that xibenjian was killed by others.

However, when people were ready to look for the music score left by Keiji ASO mentioned by the police, they found that there was no music score in the warehouse.

"Old man, do you really have the music score you said?"

Facing the questioning eyes of the police officer at dusk, the police man explained awkwardly: "ah... That... Maybe I remember wrong. After all, I'm old."

"Forget it. Anyway, the murderer has been found. The score is not important."

At dusk, the police officer waved his hand and no longer cared about the score. Then he ordered someone to collect xibenjian's body and arrested Secretary Hirata, who sold "washing powder".

Next, after a routine procedure, the police announced that the continuous homicide case in Yueying island was closed.

Although the police announced the end of the case and there was no other evidence to prove that the murderer was someone else, Conan still noticed something wrong.

For example, who is the person who entrusted Maori Kogoro to come here? Why did the timid xibenjian have the courage to kill? And Xiben Jian, who is not proficient in music, will really use notes as a secret sign to record information because of his guilt for Guiji ASO? Is the lost score really something that doesn't exist?

On the way back to the rice flower market by boat, Conan was still thinking about these things, while Bai yanzhenyu took out his mobile phone and read the newly received email.
