On vacation, on the sea of the Izu Islands, a ship sails in a white mist.

Gao Cheng silently walked to the bow of the boat and looked at the small island that gradually showed its outline in the mist.

A few days after he became a child, he received a letter of entrustment from Keiji Aso, and a commission fee of 300,000 yen was remitted to the account, and just before he took the boat here, the system also released the case this time, which happened to be the incident of Moonshadow Island.

The only impression he had of this incident was that there was a pseudo-girl named Narumi Asai, and the others were completely blurry, and it felt like the system had done something wrong.

Gao Cheng also didn't understand why he remembered a pseudo-mother, his sexual orientation was very normal, and remembering Asai Chengshi should be just a coincidence, maybe he would be a key person.

But......

Gao Cheng looked at Kogoro Maori, who was chattering and complaining on the other side, with his eyes half-open.

"Really, you can go to enjoy the flowers," Maori Kogoro muttered as he took a cigarette and glanced at Gao Cheng, "Why do I, the famous detective Maori Kogoro, have to go to that hellish deserted island with this kind of guy?" ”

"I still want to ask," Gao Cheng said dissatisfied, "Why are they also detectives, some people have a commission fee of 500,000, but as a detective, I only have 300,000?" ”

Maori Kogoro said indignantly: "Stinky boy, what kind of detective are you?" If it weren't for you, maybe I would have 800,000? ”

"Alright, alright." Mao Lilan looked at the two people who didn't deal with each other, and was caught in the middle and persuaded with a wry smile, "Just think it's a trip, there's nothing to be noisy about." ”

"Humph!"

Gao Cheng and the two of them didn't look over their heads at the same time.

I also opened a detective agency in Rice Flower Town, which is not far away, and there is already business competition, and the conflict has become more obvious recently.

A few days before coming to Izu, Maori Kogoro relied on Conan to solve a case in Saitama Prefecture, and the name of the "sleeping detective" became bigger and bigger.

In recent days, two voices, "Sleeping Detective" and "Modern Left Text", have been at loggerheads in the newspapers.

"Modern Zuo Wen" is a name that the media put on him without authorization, because he has carried a wooden knife to investigate several times, which happens to be very similar to the protagonist Zuo Wen in a detective novel many years ago.

Although Gao Fei didn't like this title, he didn't want to be compared to Maori Kogoro, and in the end it was very stiff to meet.

Kogoro Mori has Conan, and he also has a system......

Gao Cheng glanced at Conan who was pretending to be a child on the side, as long as he worked hard, he might not have the possibility of solving the case before Conan.

……

At the office in the village of Moon Shadow Island, after Gao Cheng got off the ship, the first thing he did was to go here with Conan and his party to find the information of the client, Keiji Aso.

The letters of entrustment sent to him and Mori Kogoro are all pasted in cut-out letters, which read: The next full moon night, on the island of Moonshadow, the shadows will begin to fade, please come and investigate......

It's just that there is no extra information on it, except for the postmark of Moon Shadow Island.

"Hemp, Keiji Aso?!"

The director of the office looked at Gao Cheng and the others in horror: "No, this is impossible!" Because he died more than ten years ago! ”

"What?!"

"He was born on the island, and he used to be a very famous pianist," the director said with a shocked face, "but twelve years ago, on a full moon night, he returned to his hometown after many years to hold a piano recital in the village public hall, and after the recital, I don't know why he suddenly closed himself to his family and set a big fire......

The director narrated in a deep voice under Mao Lilan's shivering gaze: "It is said that he killed his wife and daughter with a knife, and he seemed to be entangled in something in the raging flames, and he continued to play the piano, which is Beethoven's piano sonata, "Moonlight"! ”

"But what's the deal with this letter of entrustment?" Gao Cheng frowned and took out the entrustment letter, "It is indeed stamped with the postmark of Moon Shadow Island, and the commission fee has been paid off, it shouldn't be someone pranking, right?" ”

"I guess someone in your village is impersonating, right?" Not to be outdone, Kogoro Mori grabbed the director and said, "Who would do that?" ”

"This," the director subconsciously took a step back, "you can go and ask the village chief, he is on the side of the public hall now." ”

"Okay, we'll go over now!" Mori Kogoro glanced at Gao Cheng, and left after asking the location of the public hall with great energy.

Gao Cheng didn't follow immediately, but asked the staff, "Is there a one on the island called Asai Narumi?" ”

"Oh, you mean Dr. Chengshi, she should be in the clinic over there right now."

"Thank you."

Moon Shadow Island Clinic, when Gao Cheng came to find it, Conan and his party also followed, as if it was just the way to the public hall.

At this time, Asai Narumi happened to send a child away at the door of the clinic, and it was only Takasei who was looking for her (him), but Mori Kogoro suddenly couldn't move his feet when he saw Asai Narumi.

"Is it Dr. Chengsil?" Gao Cheng looked at the doctor who looked like a beautiful girl and asked hesitantly.

"Ah, it's me," Asai Narumi wore a slender white coat with long hair, "is there anything wrong with you?" ”

Before Gao Cheng could reply, Maori Kogoro had already squeezed to the front and said, "That's the case, we actually received a letter of entrustment from Keiji Aso......"

"Keiji Aso?" Asai Narumi had a look of surprise on his face.

"Yes," Takatari didn't mean to argue with Mori Kogoro, but explained anyway, "but the office said that Kei Aso had died more than twenty years ago, so I thought someone would pretend to be him and come to us." ”

"I don't know too much, because I only came to this island a few years ago," Asai Narumi shook his head and looked at Gao Cheng curiously, "Are you from out of town?" ”

Mao Lilan nodded and said, "Well, we're from Tokyo......"

"Really? I'm also from Tokyo! Narumi Asai said happily, "This island is different from Tokyo, it's great, right?" Not only is the air fresh but also very quiet......"

"Doodoo——!" As soon as he spoke, a propaganda car passed by, and the noisy horn kept echoing: Qing Shui, Qing Mizu, Qing Mizu...... Please vote for Masato Shimizu!

Asai Narumi was embarrassed for a moment, and smiled embarrassedly, "But this is an exception, because the village election is about to be held......"

"Village chief election?"

Maori Kogoro remembered the matter at this time, and hurriedly said, "We just want to ask the village chief too." ”

"Are you going to the public hall?" Narumi Asai reminded, "Tonight there is going to be a ceremony to mark the second anniversary of the death of the former village head, Mr. Kameyama, and you may be rewarded if you go there and ask." ”

Gao Cheng was a little disappointed, he had thought that he could get some useful information by looking for this only person he remembered.

Following Mori Kogoro to the public hall, there were still many villagers protesting against the current village chief at the door, and Mori Kogoro waited outside the conference room after explaining his intention to the village secretary.

However, Gao Cheng didn't stay with this guy, but took advantage of this gap to look around.

Conan hadn't realized the meaning of the letter of commission, but he was different.

Whether it was the murder incident on Moonshadow Island released by the system, or a little vague memory of his own, he knew very well that this island would not be calm in the future, and the person who sent the letter of entrustment had obviously noticed it......

But why hide your head and tail? Is there any reason why you can't reveal your identity?

Gao Cheng no longer had any expectations for finding out the true identity of the client, and the most important thing now was to investigate the events that might happen on the island.

The cause of the incident seems likely to be related to the death of Keiji Aso more than a decade ago......

Gao Cheng gently pushed open a door at the end of the aisle, and found that there was only a black piano in a large room.

Speaking of piano, he has recently gotten two piano knowledge cards, both of which he hasn't had time to try.

Gao Cheng lifted the key cover with itchy hands, and with the experience in his mind, as if instinctively, he put his fingers on the keys, which should have never been learned, but it would be like God helping him to play smoothly.

"Huh?" Conan followed behind, looking at Gao Cheng in surprise, "I didn't expect you to be able to play the piano." ”

Gao Cheng came back to his senses and snorted: "You didn't expect it too much, but I will become the world's number one detective." ”

Conan was speechless: It's too early to say such a thing, right?

"You guys!" When the village chief's secretary heard the sound of the piano, he hurriedly rushed into the room and shouted anxiously, "Don't touch that piano!" ”

"Huh?" Gao Cheng was taken aback, "What's wrong?" ”

"That's the cursed piano that Mr. Aso used in the concert on the night of his suicide!!" Hirata looked scared.

"Curse, curse?" Mao Lilan happened to follow him into the piano room, and he shuddered when he heard the words.

"Yes," Hirata fearfully pushed Takari and Conan out of the room, "it's not just Mr. Aso...... Even the former village chief ......"

"Former village chief?" Gao Cheng looked at Hirata who was in a cold sweat and asked curiously, "Is it the former village chief Kameyama Isamu who did the Dharma today?" ”

Hirata closed the door, breathed a sigh of relief, and explained in a deep voice: "It happened two years ago, also on the night of the full moon, when I happened to pass by the public hall, but there was a sound of someone playing the piano in the public hall where no one should have been around, and when I opened my mouth to ask who was inside, the sound immediately stopped......

"When I get inside," Hirata said with a horrified expression, "Mr. Kameyama collapsed on the piano, and the cause of death was a heart attack, and the music he played until he died was the same moonlight sonata that Mr. Aso kept playing in the flames!" ”

Maolilan's teeth chattered, and he was completely immersed in the atmosphere of terror: "W-It can't be Mr. Aso's ghost, right?" ”

Gao Cheng pouted.

In a detective world like Conan, nothing is more reliable than a ghost......

"Anyway," Hirata regained his composure, warned, "you better go out and wait before the ritual is over, and don't touch this cursed piano again!" ”

Outside the public hall, the full moon has appeared in the night sky, and it looks calm, but I don't know why there is a strange atmosphere.

"Really," Mori Kogoro angrily snuffed out his cigarette butt and complained to Gao Cheng, "It's all because you guy touched other people's things, and even I was kicked out!" ”

"Who knew that guy would react so much?"

Gao Cheng leaned against the door, and suddenly saw Asai Narumi wearing a black dress and walking towards the public hall with a middle-aged man.

"Huh?"

"You're still there?" Asai Narumi said unexpectedly, "Have you seen the village chief?" ”

"Not yet," Kogoro Mori was also very concerned about the village that left him aside, "It seems that I don't know how long it will be......"

"Miss Narumi," Moriran asked, ignoring Kogoro's complaints, "You're here to participate in the ceremony too?" ”

"Yes," Snarimi said with a smile, "because when I came to this island, the first person to perform the autopsy was Mr. Kameyama, so I wanted to burn incense and worship." ”

Saying that, Cheng Shi introduced the middle-aged man beside him: "By the way, this is Mr. Qing Shui." ”

"Hello, I'm Qingshui Zhengren, give me a lot of advice." The middle-aged man greeted him kindly, his face was quite upright, and his smile was also very cordial and friendly.

Gao Cheng took a look: It's the village chief candidate that the propaganda car has been shouting before, it looks good on the surface, but this kind of person shouldn't be a murderer, right?

The battle for the village chief on Moon Shadow Island seems to be fierce, and now that it's time for the village chief to be elected, someone will kill if it doesn't happen well, and coincidentally, it was the village chief who died two years ago.

"I'll see you later."

Asai Narumi and Shimizu Masato entered the ceremony hall together, and Gao Cheng and his party had to sit down at the door and wait for the ceremony to end.
