"I wonder if Kameyama, who died two years ago, counts?" Matsuda said interestingly.

"The deceased should have been killed a few minutes before the body was found," said Dr. Sung Shi.

"It's true, there is a blank space in front of this tape for five minutes and thirty seconds." Megu said, pulling out the recording and bringing it.

Hum? Matsuda looked at Cheng Shi in confusion, frowned and didn't know what he was thinking. When the person in the forensic class found something strange on the ground, Matsuda walked over and glanced at the music score, and stopped paying attention. He walked to the door and asked the police officer accompanying him: "Has no one found in the citizen hall?"

The policeman nodded: "We searched carefully. Except for them who are still being questioned, there are no other people."

It was true. Matsuda's eyes swept across Shimizu, Hirata, Murazawa, and immediately moved away when he arrived at Nishimoto's body. This kind of man didn't seem to have killed someone.

The most benefited among the three people was Shimizu, who was also a candidate for village chief, but what were the dark stories about the dead Kuroiyan and Kawashima? Then the secretary Hirata should be the one who knew the most. Matsuda scratched his head, oh, he still had too little information.

The preliminary investigation of the scene where Black Rock was killed was completed. Megu concentrated all the people present in the hall, trying to find something from them.

However, ordinary people who have a murder case suddenly have less stable emotions, and they gradually turn from ruling to quarrel.

"Do you understand? The next one is you." Conan suddenly said while people were arguing.

"Conan!?" Xiaolan said in surprise.

"A code, as long as you knock on the door, it's very simple." Conan said: "Please follow the pinyin of the piano keys, and then the music left by Mr. Kawashima when he was killed will become 'Do you understand? Next is you'. And the music score at the scene where Mr. Kuroshima was killed means 'The resentment of this sin is eliminated here'."

"Does resentment mean the pianist who was burned twelve years ago?" said the people present in disbelief.

"Keji Aso, Keiji Aso is still alive!" Nishimoto screamed in horror.

"He is indeed dead." The old patrolman walked in from outside the door: "Comparing the bones at the fire scene confirmed that it was indeed Kei and his family. Moreover, their things were basically burned down, leaving only the music score in the safe."

"Score!?" Meguro shouted together with Kogoro: "Where?"

"It's in the warehouse of the citizen hall." said the old patrolman: "But the key to the warehouse is in the police station."

"Then you go and get it!" Megu said angrily.

"Yes, yes." The old patrolman hurriedly ran out.

"Wait, I'm going too." When Conan chased him out, he glanced at Matsuda outside leaning against the wall, staring at his police manual with the faint light.

"Hey, grandpa." Conan asked the old patrolman on the way: "What did Officer Matsuda say to you just now?"

"Ah~~" said the old patrolman: "I have asked some questions about Mr. Aso."

"Can you tell me?" Conan said crisply.

"Actually, Mr. Aso and Mr. Kuroiwa, Mr. Kawashima, Mr. Nishimoto, and Mr. Kameyama are good friends who grew up together. On the day Mr. Aso had an accident, they were witnesses at the scene." said the old patrolman.

"Is this the only one?" Conan asked.

"There are some things about Mr. Murazawa." The old patrolman did not wait for Conan to ask him this time, and he finished speaking: "Mr. Murazawa came to the island three years ago. He finally got engaged to the village chief's daughter a few days ago, but Mr. Kurooshi objected very much."

"Where is Mr. Hirata?" Conan asked.

"Mr. Hirata is actually very timid and should not do those terrible things." said the old patrolman. "And Mr. Kiyomizu has a strong sense of justice and is loved by fishermen. Do you want to ask anything else? Little detective."

"Ah? Well~~" Conan turned his head to one side.

After an hour, the old patrolman finally found the key. Xiaolan ran over and urged them in a panting manner, and said that everyone in the citizen hall had already returned.

When Conan knew about this, he hurried to the citizen hall. After hearing some strange sound, Conan ran to the room where the cursed piano was stored, and saw a figure running away, while Murasawa was lying on the ground in a coma.

Then he heard Xiaolan screaming, ran back, and saw Nishimoto hanging in the warehouse. There was a suicide note made of music under Nishimoto's foot.

When he was about to be considered suicide, Conan revealed several of the doubts, confirming that this was another murder.

When Memu gathered all the relevant personnel, he suddenly found that the village chief secretary Hirata and Matsuda were missing.

"Really, Matsuda's bastard ran to somewhere at this time!" Megu was so angry that he yelled.

Could Hirata be the murderer? Conan, who has a certain understanding of Matsuda's abilities, was puzzled. But it was not right, and it couldn't be explained in many places.

When Conan saw the music score left by Aso, he flashed his inspiration and understood what happened. Then he anesthetized Kogoro and told the truth about the incident.

"I've probably understood what happened." When Conan adjusted the bow voice changer and was about to announce the truth, Matsuda's voice came from the hall.

What? It's impossible. Conan looked down at the music score in his hand. Could it be that the man really saw through the truth hidden in the fog?

"Is that true?" Meguchi was surprised at first, and then his expression turned into suspicion: "Is it true? Brother Matsuda."

"Hey, sir, do you just don't believe me?" Matsuda leaned against the door and said depressedly: "From these three cases, whether it is to fight Kawashima back to the room from the beach or hanging Nishimoto, it takes a certain amount of effort. The murderer should be a man." Speaking of this, Matsuda stretched out three fingers: "Mr. Kiyomizu, Mr. Hirata, and Mr. Murazawa."

"The most suspicious one should be Mr. Shimizu. However, Mr. Nishimoto should have no interest in him, and..." Matsuda changed his subject: "Later, I discovered another thing, which ruled out Mr. Shimizu's suspicion."

"What's the matter?" Megura asked on behalf of the people present.

"Hai*in." Matsuda said: "Kuriyan and Kawashima used the piano of the Citizen Pavilion to hide Hai*in for transactions. As the village chief secretary, Mr. Hirata, it is impossible for him to be unaware of it."

"Hai*in?" Hearing this kind of thing, Meguchi certainly couldn't keep calm: "Is it true?"

"Well, Mr. Hirata has already told me the inside story." Matsuda said: "When I learned that the police officer brought them back, I was guarding the Citizens' House and thought something might have happened there. Later, I caught Hirata who ran out."

"Ah? Then why don't you come back?" Megu said angrily: "Do you know how important clues you have."

"He kept running, and I kept chasing him. After finally catching up, I had many doubts, so I asked him a few questions on the spot." Matsuda explained.

"But, I really didn't kill anyone!" Hirata, who was handcuffed, suddenly appeared and walked in and said in fear: "I really didn't kill anyone."

"The murderer is indeed not Mr. Hirata." Matsuda interrupted at this time: "If it was because of Hae-Yin's problem, then he would not have put Mr. Kawashima's body on the piano, which would increase the chance of this matter being exposed. If the motive is not Hae-Yin, then there is only the Keiji Aso incident twelve years ago."

"The dead Kameyama, Kawashima, Kuroiwa, Nishimoto and Aso are good friends who grew up together." Matsuda lit a cigarette and continued: "I'm afraid Mr. Aso is also involved in selling Hachiha, because only Mr. Aso was able to go abroad frequently twelve years ago."

"So what's the relationship between Murazawa and Aso?" Meguri did not pick out the fault from Matsuda's reasoning.

"Mr. Aso had a son at that time and was receiving medical treatment in Tokyo." Matsuda said: "I guess he might be confused about the incident at that time, so he came to this island to investigate the matter three years ago with a pseudonym."

"What? Murazawa is Aso's son?" Meguchi was shocked: "Really? Brother Matsuda!"

"This is just a guess. The person I was listening to forensic class just now talked about Mr. Nishimoto's situation. I'm afraid that after Murazawa heard someone coming, he left his suicide note in a hurry, and left without a tiptoe. When he wanted to escape from the piano room, he was attacked by Mr. Hirata who was recovering Haiyin." Matsuda spitted out smoke and continued to say: "If my guess is correct, then in the warehouse of the citizen hall, the murderer would definitely leave some decisive evidence when he left in a panic."

"But..." Xiaolan suddenly said at this time: "But Mr. Murazawa was waiting outside the door when Miss Reiko was inquired. Then he should not have time to kill Mr. Kuroshima."

"Oh?" Matsuda looked at Xiaolan unexpectedly: "You actually remember this kind of thing."

Xiaolan blushed and whispered: "Because Miss Lingzi was very special at that time..."

"Ah, indeed, the woman who has been yelling for more than ten minutes will have some special impressions." Matsuda recalled for a moment, said with a smile, and then put away his smile: "If he had no accomplices, he would really not have the chance to kill Mr. Kuroshio."

A complicity? Megu couldn't believe it: "Brother Matsuda, would you make a mistake? I didn't find any outsiders at that time."

"No need for others, just adjust the death time of Mr. Kuroyan." Matsuda said: "Right? The village chief of Kameyama died of heart failure two years ago. Not long ago, Dr. Nakashi from Yueying Island came to Dr. Nakashi, who was not long ago. You deliberately pushed the death time of Mr. Kuroyan for half an hour, right?"

In everyone's surprised eyes, Dr. Cheng Shi showed a strange smile: "Mr. Police Officer, when did you know?"

"I doubted the first time you said the inferred death." Matsuda said confidently: "The blood coagulation process is not completed in just a few minutes, so I knew you were lying. I carefully checked the tape and found that the reverse side of the tape was completely blank for thirty minutes. So I guess that Mr. Kuroshi's real death time is not the first five minutes and thirty seconds when we heard the moonlight, but thirty-five minutes and thirty seconds. Moreover, even if the prisoner left any clues, Miss Nakami, who was closest to the scene, would have the chance to erase it easily. Moving Kawashima's body to the piano room should also be to transfer the coroner away, thereby providing convenience for the killing of Kuroshima. After all, judicial dissection cannot be conducted on the island to truly determine the cause of Kawashima's death."

"But, I can't think of how a weak girl like you drowned Kawashima on the beach. So you are just a cover-up for the real murderer. Murazawa should be your lover in Tokyo." Matsuda said mercifully: "Is it worth it to help the murderer for love?"

"No, it's not like this." Kogoro's voice came at this time.

"Ahh? You idiot actually doubted my reasoning?" Matsuda didn't realize at this time that the real Kogoro had been sleeping.

"The real murderer should be Dr. Nakashi, and his identity is Keiji Aso's son, Akashi! The surname Asai should be the surname of his adoptive parents." Conan, who had been marginalized for a long time, finally told the truth about the matter.

"That's right, Mr. Aso's son is indeed called Chengshi." The old patrolman interrupted at this time.

"What!?" Matsuda could no longer maintain that handsome posture, rushed straight from the door, grabbed the old patrolman's collar and shook it: "Why didn't you tell me such an important thing just now!"

"Huhuhuhuhu." The old patrolman gasped for a long time before he could restore his ability to speak: "It happened a long time ago, and I only remembered it later."

"Male...man!?" Matsuda's hands were stiff on his chest, his fingers were still twitching from time to time, and he couldn't believe the truth: "So, so cute... hissing, so cold! I'll have nightmares tonight... Woo woo!"

"You idiot!" Memu knocked Matsuda's head hard: "Now isn't the time to think about this!"

"Police Department! The murderer is gone!" At this time, a police officer discovered that Cheng Shi was missing.

"Ah? You are so stupid, you can't even see someone? When did he disappear?" Matsuda rubbed his head and immediately changed the subject.

"Hehe, it's time for us to turn our attention to a fool." Megu sneered.

Could it be? It was the citizen hall? Conan had to start a long-distance running again.

Dad, it's over. In the burning civic hall, the moonlight was played in the live music, and she lay on the keys and shed tears.

"Hey! Stop joking." At this time, he remembered Matsuda's voice: "Are you going to die like this? As the murderer?"

Cheng Shi looked up and saw that the burning door of the piano room was pushed open, while Matsuda stood at the door, gasping for breath.

"Aren't me?" Cheng Shi wiped off his tears and sat down.

"There are very few death penalty in Japan now." Matsuda walked in and said seriously: "But even if it is a death penalty, I think it is better to welcome death as a good person who wants to make up for his fault than to be a murderer who leaves regrets."

"What are my regrets?" Cheng Shi said coldly: "You just want me to accept the so-called fair law judgment."

"What a joke!" Matsuda shouted angrily by Nakami's attitude: "The only thing that can judge ourselves is the morality deep in our hearts!"

"Did you live a good life with Natsumi Asai's identity? Even in prison, you should enjoy your life with the name Natsumi Asai!"

After Matsuda's tough resistance rushed out of the raging flames on his shoulder, he looked down at Matsuda who was lying on the ground and fell into a coma. The last sentence he heard echoed in his ears, and his eyes shone brightly.

When Conan arrived at the citizen hall, he saw Seki holding Matsuda in a coma in ash. He walked over silently and handed over the music score.

Chengshi, you have to survive alone.

When Cheng Shi saw the last sentence of the music score, the corner of his mouth raised and showed a smile...a real smile.

ps: By the way, due to work, you need to have three months of pre-job training and report the day after tomorrow. Although you can go home every half month, it is a technical school after all, and the management should not be strict. However, the updates in the next three months may not be so frequent. If there is a Sunday, it will be updated at least every week. Of course, if the management is lax, it will not be a problem. After all, something like Conan with high IQ, it is difficult to code without looking at the animation. Then try to write another chapter, and try to code three chapters tomorrow. Apologize... It should be normal to reply in three months.
Chapter completed!
